Here's an old trick to save money and get better results at the same time.

A collection of real-world Fujifilm GFX100RF sample images, shot with its fixed 28mm-equivalent f/4 lens and no in-body stabilization, each with the exact exposure settings used to keep them sharp.

I've been shooting with the Viltrox WCL-X100VI wide-angle conversion lens on my Fujifilm X100VI, and here's what I've found.

There's still no native Nikon Z-mount fisheye, but an old discontinued F-mount lens paired with the FTZ adapter turns out to be a genuinely strong option on the Z8. Here's what you gain, what you lose, and how it stacks up against the newer third-party Z-mount fisheyes.

I've written a full technical review of the TTArtisan Tilt 50mm f/1.4 separately, but I wanted to include here a larger collection of sample images.

Tilt lenses are definitely niche, but they allow you to aggressively manipulate the focus plane to create that fun "miniature" optical illusion. The TTArtisan Tilt 50mm f/1.4 is an affordable, all-metal manual lens designed exactly for this creative purpose. I took it for a spin handheld to see if this $229 lens could deliver that eye-catching diorama look without the high price tag of traditional architectural glass.

A collection of handheld sample images from the Laowa 8-15mm f/2.8 FF Zoom Fisheye on a Nikon Z8, shot in RAW at f/2.8 and f/4 with no distortion corrections applied, showing what this manual-focus zoom fisheye actually delivers.

The Laowa 8-15mm f2.8 is a full-frame zoom fisheye lens that comes with various common lens mounts. I've been shooting with it, and here's my take.

Here are some high-resolution sample images to go along with my review of the Meike 85mm f1.4 AF Z fast prime lens.

I've been shooting with the Meike 85mm f1.4 AF Z fast prime lens. The price is certainly attractive. It's optics are very good. My biggest quibble with it is the speed and reliability of the autofocus.

Want to turn your 200mm lens into a 280mm or 400mm monster without spending thousands on new glass? A teleconverter might be the answer. But before you buy, you need to understand the 'optical tax' involved — specifically regarding light loss and autofocus speed.

My experiences with teleconverters over the years haven't been great. But this new Nikon Z 1.4x teleconverter surprised me.

Using a manual-focus lens on a Nikon Z? Here's what a non-CPU lens actually is, and a step-by-step walkthrough of the Non-CPU Lens Data menu that sharpens IBIS, Auto ISO, and your image metadata.

I've been testing the TTArtisan 11mm f/2.8, a full-frame fisheye with manual focus and manual aperture. Here are some more sample images I've taken with it to go along with my detailed hands-on review.

Here's my hands-on review after shooting with the TTArtisan 11mm f/2.8 full-frame fisheye lens.

The AstrHori 12mm f/2.8 fisheye is a fast full-frame fisheye lens. It's an entirely analog lens with manual focus and manual aperture. I've been out shooting with it, and here's my take on it.

The Viltrox AF 28mm f/4.5 Z is a fixed-aperture full-frame lens that is absolutely tiny. It's an interesting option for street and travel photography.

The Viltrox AF 15mm f1.7 Air lens is small, light, pleasingly sharp, and certainly priced attractively. After shooting with it, here's my detailed take on it.

After years shooting the heavier AF-S 14-24mm f/2.8G, this Z-mount version became a lens I actually look forward to using. Here's a large set of real-world sample images shot on a Nikon Z8, with notes on how it compares to the AF-S original and the Z 14-30mm f/4 S.

Here's a collection of sample images I've taken with the Viltrox AF 24mm f1.8 Z to go along with my detailed hands-on review.

After weeks of real-world shooting on a Nikon Z8, this fast, sharp ultra-wide has become one of my favorite Viltrox lenses yet. Here's my hands-on take on the Viltrox 16mm f/1.8 AF Z, including sample images and how it stacks up against pricier alternatives.

The Viltrox 16mm f1.8 AF Z manages to be good, cost-effective, and fun to shoot with, which is a great combination. I've been out putting it to the test on my Nikon Z8, and here are some sample images to give a sense of how it performs in real-world shooting conditions.

There are Viltrox lenses that I like. And I especially like a fast 50mm prime. So why wouldn't I recommend this one?

The Laowa 10mm f2.8 is wide, relatively fast, and has autofocus. It's also full-frame and, importantly, has very effective aspherical elements to keep things straight. I've been shooting with it. Here's my take.

I've been out shooting with the ultra-wide Laowa 10mm f/2.8 autofocus lens (full-frame). Here's a selection of high-resolution sample files I've taken with it.

There's a surprisingly large range of options available if you're looking for Nikon Z DX mirrorless lenses. Here's my running list of the alternatives from Nikon and third-party manufacturers.

At $176, the Viltrox AF 25mm f/1.7 Z undercuts Nikon's own DX primes by hundreds of dollars — but is the autofocus and optical quality good enough to matter? Here's what real-world shooting with it on a Nikon Z8 revealed, from sharpness wide open to vignetting and AF speed.

A look at real photos taken with the Viltrox AF 25mm f1.7 Z, an inexpensive APS-C prime for Nikon's Z-mount, shot mostly wide open to see what this $176 lens can really do.

There's a surprisingly large range of options available if you're looking for Nikon Z full-frame lenses. Here's my running list of the alternatives from Nikon and third-party manufacturers.

180mm is already telephoto territory, but this lens reaches all the way to 600mm on full-frame. Here are uncropped, real-world Nikon Z8 examples across the zoom range so you can see what that reach actually looks like.

A year of real shooting with the Nikkor Z MC 105mm f/2.8 VR S on a Nikon Z8, from macro close-ups to cherry blossoms at the Tidal Basin. Here's a look at the sample images and why its flat-field macro design makes it an unusually capable everyday telephoto.

If you've ever shopped for a lens and seen the phrase "35mm equivalent," you know photography jargon can be confusing. This term is the key to understanding how different cameras see the world. Here is exactly what it means and how to use it to choose the right lens.

My aim in this post is to walk through how to adjust the control ring settings, explore the default settings, and dive into the various options available so you can set it up for your own style of shooting.

I shot the Nikon AF-S and Z 105mm f/2.8 macro lenses side-by-side on my Z8 to settle a practical question: is the Z version's price worth ditching a lens I already own and use constantly.

Every time I turned my Z8 on, my exposure was off by a stop. I thought I had "Auto Reset" enabled, but I missed one critical detail about how the lens control ring behaves. Here is the fix.

The Nikon Z 40mm f/2 is probably the closest thing to a nifty fifty in Nikon's current Z lens lineup. Here are some photos I've taken with it to go alongside my hands-on review.

I've been out shooting with the small, compact Nikon Z 26mm f/2.8 lens. Here are some photos I've taken with it.

The Nikon Z 28mm f/2.8 is small, light, and very reasonably priced. Here are some photos I've taken with it.

Here's my hands-on review of the Nikon Z 28mm f/2.8, a small, light, and cheap prime lens for Nikon Z-mount mirrorless cameras.

I've been out shooting with the Nikon Z 40mm f/2 prime lens. It's a small, light, and relatively fast prime that is a great option for candids, street, and travel photography. Here's my take on it.

This 26mm pancake lens is the smallest lens in Nikon's Z lineup. And yet I'm very impressed with its performance, both in handling and in image quality. It has quickly earned a regular place attached to my camera.

A running list of Nikon lens hood model numbers matched to specific NIKKOR lenses, covering F-mount FX and DX lenses, older manual-focus glass, and Z-mount mirrorless lenses, plus what the HB, HN, HR, and HK codes actually mean.

If you're after a replacement or spare lens hood for your Sony lens, here are the part numbers to look for. Updated with the latest Sony lenses.

Laowa lenss use various codes in their names to denote compatibility or particular features. Here's how to make sense of them.

Sharp, smooth, and reasonably priced, the Nikon NIKKOR Z 35mm f/1.8 S is a highly versatile and useful lens in Nikon's expanding lineup of Z-mount primes.

Sony uses a specific set of codes to distinguish its lenses, from the entry-level "E" series to the top-tier "G Master" glass. As a relative newcomer compared to Canon or Nikon, Sony's list is shorter, but the rapid evolution of their autofocus motors (from SSM to XD) can still be confusing. Here is the complete breakdown.

Pentax users pride themselves on backward compatibility — you can mount a 1975 lens on a 2024 camera. But the alphabet soup of lens codes (DA, FA, PLM, DC) tells a different story. Some new lenses won't work on old bodies, and some old lenses need special settings to work on new bodies. Here's a breakdown of the Pentax code language.

Rokinon lenses offer incredible bang-for-your-buck, but their naming convention is a confusing soup of "Cine DSX," "AS," and "UMC." Are Rokinon and Samyang really the same thing? Does the V-AF line actually have autofocus for video? We break down every cryptic code on the barrel to help you buy the right glass for your Sony, Canon, or Nikon camera — including the modular Remaster Slim system.

The Nikon Z 50mm f/1.2 S is fast, heavy, and pricey. But it's also optically excellent. Here are some photos I've taken with it.

A look at how the Fujifilm XF 8-16mm f/2.8 R LM WR performs in real shooting, with rectilinear optics that keep straight lines straight and no fisheye bulge at ultra-wide angles. These RAW, lightly processed shots from an X-T5 complement the full hands-on review of this lens.

A gallery of real-world sample images shot with the Nikon NIKKOR Z 14-30mm f/4 S on a Nikon Z8, meant as a companion to my full hands-on review of the lens.

I've been testing the OM System M.Zuiko Digital ED 12-45mm f/4 Pro zoom lens for OM System and Olympus Micro Four Thirds cameras. Here are some quick practical examples of its zoom range to provide a visual idea of its perspective.

Get to grips with fast lenses--what they are, how they work and why they're so popular among photographers. Learn what defines a fast lens, the benefits of shooting with one, and good lenses to start with. Plus, discover some lens gotchas to watch out for.

If you've ever looked at a lens barrel and wondered why it lists an aperture range instead of a single f-stop, you are looking at a variable aperture zoom. It is a deliberate engineering compromise to keep glass portable and affordable. Here is a breakdown of the optical math behind that sliding scale, plus a look at the hidden "effective aperture" quirk that happens when shooting 1:1 macro.

There is nothing more frustrating than shooting a beautiful multi-frame landscape, only to get home and find dark, blotchy bands ruining the sky when you try to stitch it together. If you shoot panoramas, you've likely run into this issue. Here is a practical look at exactly why circular polarizers and stitched panoramas don't mix well, along with a few examples from my archive and the workarounds I rely on instead.

The Sony FE 12-24mm F4 G zoom lens has an ultra-wide perspective that adds a lot of drama and packs a lot of scene into the frame, but it manages to do it without the distracting parts that you often get at such extreme focal lengths.

Before threaded screw-on filters, lenses used a three-piece slip-on system sized by "series" number. Here's how Series 7, 8 and 9 filters actually attach, and why you'll still meet the term on vintage manual-focus lenses.

Here are the part numbers for the lens hoods for common Fujifilm/Fujinon lenses, including X series and GFX series lenses. Updated with the latest Fujifilm lenses.

Many Canon lenses come with a dedicated lens hood that is optimized for that specific lens. If you need a replacement or spare lens hood, these are the compatibility charts with the lens hood model numbers. Updated to include the latest Canon lenses.

I've previously posted a detailed review of the Nikon AF-S 85mm f/1.4G. Here are some high-resolution sample images I've taken with it.

I've been out shooting with the Fujifilm XF 8-16mm f/2.8 R LM WR ultra wide-angle lens on the new Fujifilm X-T5. Here's my take on it.

There is no name more distinguished in optics than Zeiss, but their naming convention is anything but intuitive. Unlike other brands that use tech-jargon, Zeiss names lenses after birds and century-old optical formulas. From the autofocus Batis to the manual-focus Milvus and the legendary T* coating, here is a plain-English guide to understanding exactly what you’re buying when you see that famous blue badge.

Tokina lenses are legendary for their "built-like-a-tank" construction, but their naming system has undergone a massive overhaul recently. If you’re confused by the jump from "AT-X" to "atx-i" or "opera," you aren’t alone. Here is the definitive guide to every code Tokina uses, including their unique Focus Clutch mechanism and their 2026 mirrorless lineup.

Tamron Di, Di II, Di III, VXD, SP — what do they actually mean on a lens barrel? This guide breaks down every current and legacy Tamron code, from sensor compatibility to autofocus motors and glass coatings.

Sigma lens names can be a mouthful of acronyms. Once you know how to read them, however, they are a powerful shorthand for identifying whether a lens is built for full-frame or crop sensors, DSLRs or mirrorless cameras. This guide demystifies the alphabet soup so you can quickly categorize any lens in their massive lineup.

As a relative newcomer to the modern mirrorless game, Fujifilm hasn’t accumulated the decades of confusing acronyms that Canon or Nikon have. But their naming convention is precise, and knowing how to read it will tell you exactly what you are buying — and whether it has that all-important aperture ring.

VR? ED? S-Line? Plena? Nikon lens names are a alphabet soup of confusing abbreviations. This guide decodes them all — from the latest Z-mount tech to vintage manual focus terms — so you know exactly what you're buying.

Like most lens manufacturers, Canon uses codes in their lens names to identify key features and technologies of the lens. They might look like a look like a random jumble of letters, but they are actually a precise formula. Once you know how to read them, you can instantly tell if a lens will fit your camera, how fast it will focus, and whether it is weather-sealed.

Here are some real-world examples of the zoom range of the Fujifilm XF 8-16mm f/2.8 R LM WR ultra-wide-angle zoom lens.

I've been out shooting to test out the OM System M.Zuiko Digital ED 12-45mm f/4 PRO zoom lens. Here's a selection of images I've taken with it.

Fisheye lenses pack a dramatic, distorted view into the frame — great for tight interiors and immersive action shots, terrible for portraits and architecture. Here's what to know before you shoot with one, including the two main types and what to avoid.

With a fast maximum aperture combined with a short telephoto, the Nikon AF-S 85mm f/1.4G offers wonderful opportunities for isolating a subject from its background and shooting in low light. Here's my take on it.

Here's a selection of sample images I've taken with the Olympus M.Zuiko Digital ED 12-100mm f/4 IS PRO zoom lens. I've included a range of settings and lighting conditions to give a sense of how it performs in real-world shooting conditions.

Fisheye lenses are powerful creative tools, but not all of them work the same way. Some create a floating circle, while others fill the frame with curved drama. Nikon currently offers three very different options — from the vintage 16mm prime to the modern 8-15mm zoom. Here is my breakdown of how they compare.

The Nikon AF-S 50mm f/1.4G lens comes with a perfectly good lens hood included. But there's another option I've found to work better for me.

I've been testing the Sony E 20mm f/2.8 wide-angle lens for Sony E-mount APS-C mirrorless cameras. Here are some high-resolution sample images I've shot with it.

Because Nikon's crop-sensor (DX) DSLRs share the exact same lens mount, finding the perfect wide-angle lens for sweeping landscapes or tight real estate photography is the same whether you shoot with an entry-level D3500 or a flagship D500. Here are my practical recommendations for the best wide-angle options for your Nikon DX camera.

Sigma has two zoom lenses at the 150-600mm focal lengths. Here are some sample images I've shot with the Sports version, which is bigger, heavier, and much more expensive than the Contemporary version, but also offers much improved optical performance.

The Nikon AF-S 8-15mm fisheye zoom lens is optically excellent and opens up some fun creative opportunities. There are also some quirks when shooting with it.

That narrow ring near the camera body isn't just for manual focus — Nikon calls it the Control Ring, and it can be reassigned to aperture, ISO, or exposure compensation. Here's exactly where to find that setting in the Z6/Z7 menus, for both photo and video modes.

Here's a collection of photos I've taken recently with the Nikon NIKKOR Z 24-70mm f/4 S zoom lens. All of these were shot on a Nikon Z7 body.

Here are some practical examples of the zoom range of the Nikon NIKKOR Z 24-70mm f/4 S, with side-by-side examples shot at 24mm and 70mm.

Why buy three expensive polarizers when you only need one? Step-up rings are the secret weapon of pro photographers, allowing you to adapt a single high-quality filter to fit almost every lens in your bag. Here is how they work.

There is nothing more frustrating than a filter that refuses to unscrew, especially when the light is fading. But before you reach for the pliers (don't!), you need to understand the physics of why it's stuck. Here are the safest ways to remove a seized filter without damaging your lens — starting with a very old trick that works like magic.

Here's a quick rundown on using some of the most common types of screw-in filters and considerations when using them.

Looking for the right filter size? You don't need to guess. I've compiled a master list of lens diameters for the entire Nikon lineup — from the latest Z-mount releases (like the Plena) to vintage manual focus glass — so you can buy the right screw-in filter every time.

Look up the filter thread size for your Canon lens by mount, whether RF, EF, EF-S, or EF-M, across current zoom and prime models. Updated regularly as new Canon lenses are released, plus tips on step-up rings and polarizing filters.

Why is the jump from f/5.6 to f/8 a full stop, but f/1.4 to f/1.8 is only two-thirds? The math behind lens apertures is famously counterintuitive, but mastering it is the key to perfect exposure. We’ve built a custom, mobile-friendly F-Stop Calculator to help you instantly solve for ND filter offsets (including Big and Super Stoppers) and compare increments across the entire range — from f/0.95 "Noct" glass to f/32. Use this interactive tool and charts to take the guesswork out of your next shoot.

In the age of AI editing, many physical filters have become obsolete. But there is one that remains essential: the Circular Polarizer. Why? Because it manipulates light physics before it hits your sensor, removing glare that software simply cannot 'see.' Here is how to use the '90-Degree Rule' to capture shots that are impossible to fake.

If you're finding that the autofocus isn't focusing exactly where you want it, some cameras offer calibration tools. Here's how they work.

For years, if you wanted the best 35mm f/1.4, you bought Nikon or Canon. Then Sigma released the "Art" series and shook tings up. At nearly half the price of the Nikon equivalent, the Sigma 35mm f/1.4 DG HSM isn't just a budget alternative — it's optically excellent and a very attractive alternative. Here is my field test.

The 35mm focal length is the storyteller's lens — wide enough for context, tight enough for portraits. Nikon’s f/1.4G version promises optical perfection with Nano Crystal coatings and a 9-blade diaphragm. But shooting wide open at f/1.4 reveals some quirks that require careful calibration. Here is my hands-on review.

A hands-on look at Nikon's tiny, discontinued AF Fisheye-Nikkor 16mm f/2.8D — how it handles sharpness, low light, filters, and spherical panoramas, plus how it compares to the 10.5mm and 14-24mm.

Confused by the numbers on your lens? You aren't alone. The most common mistake beginners make is trying to find a filter that matches their focal length (e.g., 50mm) instead of their lens diameter. Here is how to decode the 'ø' hieroglyphics on your lens barrel and why you should never buy a separate filter for every lens you own. And once you know what to look for, it's easy.

An ND filter blocks light, meaning you can use a slower shutter speed or larger aperture. The Tiffen Variable ND Filter sounds great on paper, offering flexibility and convenience. Here's how it performs in practice.
