What a great lens. I still haven't been able to convert the mount, and may never, but at least now I'm getting to use the lens. I had one of the optical adapters that I really don't like using. It's not bad, but it definitely degrades the lens, so I've concluded that it doesn't make sense for me. I removed the glass from the adapter and it now serves as an extension tube of sorts. The working distance is now quite short with the focus range being approximately seven to nine inches from the front of the lens - and that's only an estimate.
I've had this Rokkor for 36 years (jeesh, that makes me sound old) and always liked the results, but in the film days it was hard to fully evaluate a lens. Now using this Rokkor in near macro mode it has surprised me with not only its sharpness, but colors and "dynamic range". I don't think a lens is really capable of giving dynamic range, but for whatever reason, I have found that this lens isn't washing out the highs like in my other close focus attempts and I'm getting more detail in dark areas as well.
Here's a 33% crop picture of an orchard spider that I've been photographing all summer:
The same spider at f/2.8:
Dragonfly mild crop:
Whatever they are at f/1.4:
Another bad boy (sorry, I had underexposed):
And a small flower followed by a 100% crop:

I use a SONY A200. I would need to trim 1mm from the registration. If using an M42 adapter, I need to trim nearly 2mm to compensate for the <1mm adapter.

Yep, that's the MC (pre MD) still a great lens, but it's possible there were some improvements to coatings in the MD (last manual focus series) plus the aperture was engineered better in the MD...I like the second gen. MD lenses myself.
Yep, I've got two of these MC 50/1.4's and I'll be using an M39-EOS adapter and doing this: http://www.flickr.com/photos/andddre/sets/72157623018600542/with/4113551278/

If they were, I'd have done it already. Motleypixel provided a link to an excellent tutorial on how to convert to Canon. I suppose the same approach can be taken to convert to A-mount, but it looks scary to me as someone that does not have metal working equipment, not to mention all those tiny and hard to see parts.

I've got the MD version, I've tried it on the XD7's and like it a lot, I'm just waiting for a MD adapter to arrive any day now so I can try it on my NEX.
It's the lens I'm looking forward to trying the most, and your pictures just reinforce that.

True, but this one is not just not bad: actually it's my favorite 50 in my collection.
The only problem is that I can't mount it properly on my Sony dslr: I have to choose between losing infinity or keeping glass in the adapter, that makes the lens unusable wide open.
Really nice shots, btw.

I see the challenge of adaptors.
Cases of wide open at infinity shot are rare then.
Personally, I rather lose infinity than use a glass adapter.
I recall that 58/1.4 had less good review/opinion and turn out to be good after my tastes.
Except for older lenses, some with swirly and/or harsh bokeh in certain distances, all 50-58 i tested are good. |

Thanks for comments. I will be using this lens more now that I can use it in normal ways. The earlier pictures were the close-ups when I was limited by adapter on Sony A200 DSLR. I originally tried the adapter with corrective glass and didn't like the results, so I removed the glass and used it as a straight adapter for close-ups. I've just gone back and edited my earlier pictures to defeat hosting compression and provide a better image.
I also have the MC Rokkor-X PF 50/1.7 and several others at the focal length. I'm curious myself in making some comparisons. Possible candidates include:
58/1.8 Topcor
58/2 Helios
55/1.4 Mamiya Sekor
50/1.4 Hexanon

Challenges need to be solved 
Cause I got some Minolta lenses I want to use on EOS I thought an experimented regarding adapting Minolta lenses to Canon
, and made an adapter. The lens need to be infinity adjusted, and the iris lever must be removed (this could be reversible or with force). But it can still be used on the Minolta cameras - only without all the iris automation.

I was shooting in the f/6.3 to f/8 range with the last one at maybe f/2.8-ish. In this environment it is sometimes difficult to shoot for shallow depth of field as the sun is very bright and my camera is limited by ISO100 and 1/4000. Sometimes I have to stop down until I get to below 1/4000.

Have you tried using an nd filter or polarizer (poor man's nd - gives 2-3 stops less light!)?
You can maintain shallow depth of field even in bright sunshine. polarizer can work nicely on dreamy waterfalls too.
You might get slight loss of iq - really subjective I think.
regarding alpha mods - Jim Buchanan specializes in Minolta lens conversions - maybe worth a shout for info even tho he mainly deals with leica/eos www.jimbuchananspace.com/Camera_Services.html .
