My Great-Grandpa was a professional photographer and we have two of his DSLRs. I was wondering if I could use the lenses on my camera. Is there an adapter that I could get to make them work on it and would they take quality pictures?
So here are all the numbers and letters.
both Minolta SR-7
Minolta auto Rokkor-PF 1:1.4 f=58mm 1248480
Minolta auto Rokkor-PF 1:1.8 f=55mm 2431642
That is everything that is on the front of the lenses.
Thank you for any advice!May 14, 2019 at 6:49 pm #39695Josiah WaldnerParticipant
I think this should work. I’m not positive the lenses you mentioned are MD mount, so you might want to double check that. As far as image quality goes, it has a corrective lens built-in that lets the lens still focus to infinity. This may or may not degrade the quality a bit, but I can’t really say for sure. You might not even notice.
You’ll have to use manual focus, and there is probably a manual aperture ring on the lens as well. Don’t worry about the focus too much- you’ll find that these old lenses that have real focus rings, rather than focus by wire, are extremely smooth and accurate. You will not be able record metadata from the lens, such as focal length and aperture settings because it has no contacts. It may take some getting used to, but I would try it. That 58mm f/1.4 is probably a very, very nice lens.May 16, 2019 at 12:19 pm #39732James StaddonKeymaster
Thank you @josiahw!
Is that what you need @blessingscaptured?
And a comment about your statement, “we have two of his [Great Grandpa’s] DSLRs”….the Minolta SR-7 would just be an SLR, a Single-Lens Reflex camera. That’s what SLR stands for. A DSLR is a Digital Single-Lens Reflex camera, which wouldn’t exist in your Great Grandpa’s day. 🙂May 16, 2019 at 1:00 pm #39734
Thanks @JosiahWaldner I think that it’s a SR-mount. but I don’t know if the MD is interchangeable.
That’s right @JamesStaddon it would be a SLR not a DSLR!
What things should I check on the lens to make sure that they’re still in good shape? Just make sure that everything moves freely? The 85mm DOF preview button sticks sometimes but that shouldn’t be a problem, should it?May 20, 2019 at 2:58 pm #39868James StaddonKeymaster
The main thing when it comes to checking out a lens is to see if there are any scratches on the glass (on both sides of the lens). If a lens has autofocus, then make sure that works and how fast it is. Look for signs of it being dropped, as that could cause misalignment on things internally. I’ve heard it said that if a lens hasn’t been taken care of, there could be mold inside due to condensation, but I’ve never found that before. Also check to see if it has “lens creep” or if there are any scratchy noises you zooming in and out. Those are the things I know to look for!May 21, 2019 at 3:26 pm #39922Josiah WaldnerParticipant
I did a little research, and I believe that a SR lens will fit a MD mount. Can’t say for sure, but I as near as I can tell, the MD mount is a universal mount for Minolta lenses. They had several different ones, just as Canon had EFS, EF, and EFL But they all fit one camera. @JamesStaddon has good advice on inspecting the lenses, but since you already have them, I wouldn’t worry about them. They are both primes, and about the only thing that can misfunction on a old manual lens is the aperture ring jamming. If it works, and you can see the blades close down as you turn it, it’s probably fine.June 5, 2019 at 8:57 am #40434
The lenses are for a 35mm camera if I put them on a crop sensor camera what, if any, will the crop factor be? Would it be the same as with a full-frame to a crop sensor?June 5, 2019 at 8:22 pm #40439Ezra MorleyModerator

It should be the same crop factor as if you were using an FX lens on your DX camera body. So the 58mm will be ~87mm, and the 55mm will be ~82.5mmJune 6, 2019 at 8:49 am #40450
Thank you. It will be what I’m used to on my 18-55mm. I use 55mm a lot.
