    Hello,

    I have been looking for a legacy lens between the focal lengths of 24mm and
    35mm. I have a vintage 50mm Minolta Rokkor that I really like, especially the build quality. So I entered into a few Ebay auctions for a 28mm Rokkor, and actually won two 28mm lenses by accident! I only meant to buy one. But the good thing is I actually get to test both lenses and keep the best! Does anyone know anything about these lenses? I appreciate the older Rokkor for it's build quality, but I know it's a stop slower. What do you think the outcome will be of my testing? Here is what I won...

    MINOLTA MC W. ROKKOR-SG 1:3.5 F=28mm LENS

    Minolta 28mm W. Rokkor f2.8 MD Mount

    Thanks!

    Nathan

    Generally most Minolta lenses are optically a bit better in the older MC generations. I haven't read or found a direct test comparing the two 28's. My experience with MC/MD lenses on our system is that you'll have to stop down a bit to get the contrast and sharpness up. The only ones I have to compare are within 50mm models (as far as both mounts are concerned). While I prefer the bit lighter MD mount version, I like the focus ring and IQ from the earlier MC Rokkor-X more.

    The MC mount you have looks to be a second generation with that knurled focus ring made probably towards the late end of 1966-1973.

    The MD mount model is a second generation MD model. Manufacturing started in 1977 for the first generation, so I would guess it's from the 80's.

    Everything you want to know about Minolta rokkors can be found at a site called the rokkor files.

    Thanks Danska! I've pretty much found that stopping down with my legacy glass was the only way to go as well. I have a Nikon 50mm 1.8 that was fine wide open on my old Nikon, but it's definitely best at 5.6 on the GX1. Also thanks to Grinch and Barefoot... I have visited that site. I just don't see any review for the older version of the 28mm. It's a great site though!

    It just so happens I collect Minolta 28mm lenses. Your MC 28/3.5 model was introduced in 1969 and superseded by a similar model with a rubber-clad focussing ring in 1973. The MD W.Rokkor 28/2.8 ø49mm was offered between 1978 and 1981. It's probably much better than your MC 28/3.5: more contrast, better corner sharpness. Both lenses perform best at f/5.6 to f/8; the best 28/2.8 samples are already quite good wide-open, but quality varies across all 28/2.8's I have and had. I've had more than 5 models of this MD W.Rokkor 28/2.8 with 49mm filter thread and they were all very much alike and quite good. I think this model is your best bet if you want to use a Minolta 28/2.8, it also handles nicely because it's small and fairly light.

    In bookmaker terms: MD 28/2.8 1.2:1, MC 28/3.5 8:1 :smile:.

    Why is that the case? I tried a Sony 35/1.8 on my EPL, it looked pretty sharp to me.
