When you're shopping for camera accessory adapters, the decision usually comes down to two things: which mount pairs you need to connect and how much electronic communication you expect. Old lenses and new camera bodies don't always share a mount, so the right adapter can turn a shelf full of glass into a usable kit again. Here are four adapters that tackle different lens-and-camera combinations. The key is to match the physical mount, then weigh the listed features and price spread.
Quick take
If you have old lenses sitting around, a lens mount adapter can put them back to work on a newer body. The four adapters here cover Minolta MD/MC to Nikon F, Nikon F to Nikon Z, Minolta/Sony A to Sony E, and M42 to Canon EOS. The Viltrox NF-Z is the adapter with the most electronic features, while the other three are simpler mechanical adapters. The best pick depends on the lens mount you already own and the camera body you want to use. Once you know your mount pair, the price spread and feature list will guide you.

| M42 to Canon EOS | Canon EOS users with M42 mount lenses | AF-confirm chip |
Product notes
#### Minolta MD/MC to Nikon F AI Adapter
At USD 11.09, this aluminium adapter is built for Minolta MD/MC mount lenses to Nikon F AI mount cameras. The screw-in fastening makes it a simple mechanical connection, and the listed portable feature means it won't weigh you down. It is designed specifically for the Minolta MD/MC-to-Nikon F AI pairing. The limitation is that this adapter only covers that one mount combination, so photographers with other lens mounts should look elsewhere.
#### Viltrox NF-Z Auto Focus Lens Adapter
At USD 88.00, the Viltrox NF-Z is the highest-priced adapter in this comparison, and it lists auto focus, EXIF transmission, electronic aperture control, and built-in image stabilization. It is designed for Nikon F-mount lenses on Nikon Z-mount cameras, including the Z5, Z7, Z9, Zfc, and Z50. The twist-on fastening and the included caps make it a complete adapter for that specific pairing. The trade-off is the price and the compatibility: this adapter is only for Nikon F to Nikon Z, so it won't help with other lens-mount combinations. If you're staying within the Nikon F-to-Z world, it preserves the electronic connection between lens and body.
#### K&F Concept Sony/Minolta A to NEX E Adapter
At USD 24.49, this K&F Concept adapter is a middle-priced option for Sony Alpha Minolta AF A-type lenses on Sony NEX E-mount cameras. It is made with brass and aluminum construction, is manually operated, and supports infinity focus. It is compatible with a wide list of Sony E-mount bodies, from NEX-3 to a7, a7R, a6000, and a6500. Because it is manually operated, you have to focus by hand and set the camera to function without an E-mount lens attached. The trade-off is that this adapter is manual-only, so it won't provide the electronic features found on the Viltrox NF-Z in this lineup.
#### M42-EOS Lens Adapter Ring
At USD 6.67, this is the lowest-priced adapter in the lineup. It connects M42 mount lenses to Canon EOS cameras and includes a third-generation AF-confirm chip and infinity focus capability. EXIF is fixed at 50mm f/1.4, so the metadata won't reflect your actual lens. Because the lens aperture isn't controlled by the camera body, you'll need to manage exposure yourself. It's a straightforward adapter for M42-to-Canon EOS shooters.
Final recommendation by use case
If you're pairing Minolta MD/MC lenses with a Nikon F AI body, the aluminium adapter is the one built for that exact job. For Nikon Z shooters who want to keep using F-mount lenses with the electronic functions that matter to them, the Viltrox NF-Z is the adapter that maintains that link. If your lens collection is Sony Alpha Minolta AF and your camera is Sony E, the K&F Concept adapter gives you a dedicated bridge for that mount pairing. And for M42 lenses on Canon EOS, the lowest-priced adapter in this group is also built for that pairing. Each adapter solves a different mount puzzle, so your choice comes down to the lenses and camera body you already own.
