But there's no doubt the OM is nice on the A7R -- small, light, well balanced, smooth to operate, nice built in hood etc.
Have to try that one as well. Seems I don't yet have OM -> E-mount adapter, need to order few. EDIT: Checked mine and it's actually not the same but f/3.5 version. I almost didn't find it since I was looking something Contax 135mm f/2.8 size lens, but this one is half the size...
Today I was again enjoying short flange distance benefits, this time with Minolta MC Rokkor-PG 1:1.2 f=58mm. I have wanted this lens ~5 years, but never bothered to convert one to EF-mount. Light was really crappy, most of the time about f/1.2, 1/100s, ISO 250 - few times clouds let little more light past them and was able to shoot few frames with ISO 100. Luckily A7 seems to produce usable results even at ISO 400. For web even ISO 6400 does very well, but for normal print size & screen evaluation ISO 800 starts to be too noise for my taste.
BTW. Is it normal for Rokkor 58/1.2 to show slight glow when shoot wide open? It can be seen at least on #01 and #03. And on #04 the part of image, which is between focus point and camera is lighter/brighter than it would be if it would be in focus.
Notice: Vignetting has been decreased by settings in Iridient Developer (otherwise default slide positions on vignetting correction but moved first slider from 0 to 25)..
#01. Rokkor 58/1.2@f/1.2, 1/100s, ISO 100

#02. Rokkor 58/1.2@f/1.2, 1/320s, ISO 200

#03. Rokkor 58/1.2@f/1.2, 1/320s, ISO 200

#04. Rokkor 58/1.2@f/1.2, 1/100s, ISO 200 - foreground bokeh rendering is quite nice, somehow the parts in front of focus plane ger lighter/brighter than they would be in focus

#05. Rokkor 58/1.2@f/1.2, 1/80s, ISO 200

#06. Rokkor 58/1.2@f/1.2, 1/100s, ISO 250

#07. Rokkor 58/1.2@f/1.2, 1/100s, ISO 250 - have to be careful, bokeh can get really ugly as well, example:

#08. Rokkor 58/1.2@f/1.2, 1/100s, ISO 400

#09. Rokkor 58/1.2@f/1.2, 1/80s, ISO 400

#10. Rokkor 58/1.2@f/1.2, 1/60s, ISO 500

#11. Rokkor 58/1.2@f/1.2, 1/60s, ISO 640

Most testphotos were same locations as Canon FD 85mm f/1.2 L test photos exactly week ago, they can be found from here.
