I found a nice 135mm lens for my camera for only $55! Well, I found that lens for my old Minolta film camera (both purchased on eBay), but it works perfectly with my Sony A7III mirrorless, too. And we’re talking about a legitimate lens; this isn’t some weird cheap plastic knock-off. The lens is a Minolta MC 135mm f2.8 Tele Rokkor-PF and all I needed to get it to work with my Sony was a simple $16-$20 lens mount adapter.
I purchased the Fotodiox Lens Mount Adapter (MD – NEX) from Amazon. There are, of course, adapters for different lens-to-camera combinations, too. The “MD” and “NEX” pretty much mean Minolta-to-Sony in this case. This adapter will work with Minolta MC or MD type lenses or any lens, I suppose, with the Minolta SR mount. The camera end of the adapter attaches to Sony cameras with the NEX, E-Mount, ILCE type designations.
Using a lens mount adapter will allow you to take advantage of the lens arsenal you’ve built up over the years, and apply it to the purchase of a new camera. Or, as in my case, you can save money on additional lenses originally made for film cameras. You’ll probably lose some of the features you’d get with more compatible gear; there’s no autofocus on my old Minolta lenses, and I have to adjust f-stop via the aperture ring. And, as I point out in the video, you’ll probably want to use focus peaking on your camera to nail that focus.
Here are some demo shots I did with this lens/camera combo at the park the other day:
Note that the background areas are pretty far away, but you can see the difference between the two apertures I shot with (f/2.8 & f/11).
You can see more results using the Minolta with the 135mm as well as the kit 50mm in this post.
