Vintage Minolta MD/MC mount lenses on Canon EOS EF mount?

I made a huge discovery this Christmas! The video tripod post will have to wait a bit, as I just had to get this off my chest. When I was visiting my folks, I remembered that my dad used to be into SLR photography back in the film days. He had an old Minolta camera, probably an SRT101 or a similar model, I can’t remember. My granddad also had the same camera and when he passed away 15 years ago, dad inherited all his camera gear. All that gear has just been sitting in my parents’ attic, gathering dust and while the camera body was a goner, the lenses looked just fine! There was 10 manual focus Minolta MD

and MC mount lenses just waiting for me to play with them…woohoo!! There’s lots of talk over on cinema5D about how awesome vintage lenses are, because they are cheap and sharp and designed to be focussed manually, unlike modern AF lenses. There were a fast nifty fifty (the Minolta MC Rokkor-PF 55/1.7), a tele prime (The Tokina 200/3.5) two tele zooms (The Hanimex 55-220/3.5-4.5 and the Beroflex 80-210), a wide-angle prime (The Admiral G.M.C. 28/2.5), a wide-angle zoom (The Samyang 18-28/4-4.5) and a macro zoom (The Sigma 35-70/2.8-4). All I needed was a cheap adapter ring off eBay and I’d be ready to go! Or so I thought…

After my initial giddiness, I had a closer look and noticed that some of the lenses were beyond hope…they’d been completely scratched into oblivion. I still had 7 lenses left though, that appeared free of any major scratches or other blemishes, which, for the price of $0 was still an awesome find! Upon my arrival back in Melbourne, I started doing some research into MD mount lenses and how they work with Canon’s EF mount. The result was quite sobering, as the general consensus among vintage lens enthusiasts in this regard was ‘not very well’.

The lenses usually favoured by said enthusiasts come with M42 mount, which is easily adapted with a $10 adapter ring. It turns out, however, that the Minolta mount is a slightly different story. I still don’t understand why they don’t work as well, but it’s something to do with theĀ  distance between the lens elements and the focal plane. Essentially, MC/MD mount lenses are too far away from the focal plane and therefore won’t focus to infinity, even with an adapter ring. This means that unless all you shoot is macro, you’re in for a bit of trouble!

Luckily, there is an alternative in the form of an optical adapter. Optical because they contain an optical element (like a lens) to make up for the difference in length…I think. Feel free to correct me here, as I’m still new to this whole thing. The reason why this type of adapter is not ideal is because it (supposedly) deteriorates the image quality, since you are effectively adding more lens elements of inferior quality to the mix. Kind of like wearing glasses under your sunglasses?

I ordered both types of adapters from eBay and they’re in transit. As soon as I’ll get them, I’ll do some test shots and will post them here.
