Hi I'm new to this forum, I'm a self confessed Minolta nut my collection at present is as follows : 2 x SRT101, SRT303b, XE, XD, X500, AF5000, 2 x AF7000, AF9000 plus a couple of SONY DSLRs which use the Minolta AF lenses. I have a load of lenses but generally use my MD 35-70 f3.5 (the 'macro' version) and a Vivitar Series 1 70-210 f3.5 (Kiron). The AF lenses that are usually employed are my 35-40 f4 (macro) and my 70-210 'beercan'. I have several MC and MD primes which occasionally get an outing with one of the SRTs loaded with monochrome.

Minolta, a venerable name and much lauded for the colour rendition of their Rokkors. I am, however not entirely pleased with one of their products.
This morning I exercised some of my vintage glass. Rain yesterday, hence very clear air, so I went up on a hill with a good view.
My conclusion was that my Leitz (Minolta made) 500mm catadioptric should be retired. No opinion on Minoltaglass in general, but this one does not stand up to he competition.
Yes, I know that it is very difficult to find exact focus, so I took about 5 snaps , refocussing every time and compared them with the two other catadioptrics I have. Leitz-Minolta lost. I will do a retrial, weather permitting. very With long lenses, athmospheric distortion plays tricks, cold mornings are best, but with minutes separating exposures, conditions should be similar. Strong winds today, however, so the tripod might not have provided enough stabilizasion. On the other hand, that challenge would have been similar for Olympus and Nikon.
Cat lenses are little sods to get right I have a 500mm f8 cat which can give good results about 20% of the time even at quite long distances the depth of field is minimal and the "doughnuts" in the out of focus areas don't improve the results. I've resigned myself to the fact that apart from air shows it stays at home
