Rise Up -- NEX-5N & Minolta MD 85mm f2
Got this Minolta MD 85mm f2 along with the RF Rokkor 250mm f5.6 mirror lens. Compared to the MC-Rokkor 85mm f1.7, this lens is much smaller and half as heavy. Very compact with a 49mm filter size but of course is a 1/3 stop slower than the f1.7 sibling. Unfortunately, the focusing ring is a tad too tight, making it hard to adjust fine focus. It's usable but annoying. It needs to be adjusted.
As with most Minolta manual focus lenses, the image quality does not disappoint. I haven't really gotten any really bad MD/MC primes yet. Practically all of the old Minolta lenses (no zoom) I have tried are excellent. Many people like this better than the MC-Rokkor 85mm f1.7 due to its smaller size/lighter weight. To me, I still prefer the all metal f1.7 version, not to mention the 1/3 stop of extra light coming into the sensor. Perhaps, one day, I will find some time to do a comparison of these two very desirable lenses.
