From mercury-cell SRTs to the AAA-powered Maxxum 7000, Minolta cameras take a surprising range of batteries. These charts, pulled from each model’s own manual, sort out exactly which one fits yours.
Which Battery Does Your Mamiya Camera Take?
Not all Mamiya medium-format and TLR cameras need batteries at all to shoot. Several models are mechanical-only, designed to be used with external light meters. Others require a battery for the built-in light meter. And in one case, the shutter won’t fire without a battery.
Sigma Camera Battery Compatibility Charts
Sigma’s camera lineup is small enough that one battery, the BP-51, covers most recent models — the fp, fp L, and all four dp Quattro compacts. This chart lays out exactly which pack each Sigma body takes, plus which models can charge over USB.

How I Used an AI Assistant Instead of Recovery Software to Recover Deleted Photos from a Memory Card
Instead of reaching for recovery software, I asked an AI coding assistant to recover a camera-formatted SD card — and it got back 52 of 53 photos, verified byte-for-byte and automatically renamed into dated folders. Here’s exactly how it worked, and when you’d still want the packaged tools instead.

Choosing an SD Card for the OM-1 and OM-1 Mark II
Faster isn’t always better: the OM-1 and OM-1 Mark II don’t need the priciest V90 cards to hit full burst performance. Here’s the UHS speed class, capacity, and card picks that actually match what these cameras demand.

Native vs Extended ISO Range Explained
Many digital cameras these days come with impressive ISO ranges. But if you look at the specs more closely, they’ll often break it down into native ISO and extended ISO. Here’s an explanation of what that means.
Pentax Lens Codes
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.

Series Filters: the Three-Piece System Behind Vintage Lenses
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.
Keeping the Wrong Kind of Light Out of the Camera
We expect light to come in the front of the camera. Shooting with the lens cap on doesn’t tend to work so well. But we don’t always expect it to come in the back. Here’s a real-world example of light leak through the viewfinder.
Hot Shoe, Cold Shoe, and Sync Cords Explained
That small rectangular mount on top of your camera does more than hold a flash in place — it sends an electrical signal between camera and accessory. Here’s how a hot shoe works, how it differs from a cold shoe, and whether you need a cover.

Extracting Embedded JPEGs from RAW Files: Three Tools That Work
Hidden inside every RAW file is a JPEG your camera generated at the moment of capture. Most photographers don’t know it’s there. Getting it out is fast and nondestructive, and there are good reasons to do it — from preserving in-camera film simulations to salvaging files that are too corrupted to open. Here are the tools that make it easy.

Using Lightroom’s Dehaze Slider to Hunt Down Sensor Dust Spots
The Dehaze slider is designed to cut through haze and mist, but it’s also one of the quickest ways I’ve found to track down sensor dust spots that are too subtle to see in the original file. Here’s how I use it, with a couple of real-world examples.
Batch Processing Photo Merge of Bracketed Images in Lightroom Classic
This is a really neat little workflow trick I came across recently that’s already built into Lightroom Classic. It helps speed up things when using the Photo Merge process when shooting exposure-bracketed images to merge into a single HDR image. So it’s especially useful for high-volume exposure bracketing shoots like real estate and architecture, but it works just as well for any other bracketed shoots.
DxO PureRAW 6 Review: What It Actually Does to Your RAW Files (Tested on Six Cameras)
DxO PureRAW offers a different way to handle RAW files. It doesn’t process them directly, but rather prepares them using special optical enhancements based on DxO’s camera and lens research. You can still use your preferred RAW processing app alongside it.
