I was expecting a lot from the Jupiter 21M because I was fully satisfied with the little brother Jupiter 37A (135mm M42 prime).
What a great lens : the Jupiter 21M is the sharper at all aperture. It correspond to what I observed in real life shooting. I think it would be interesting to compare it with a fast 70-200 f/2.8 (expensive!) zoom @200 @f/4.0
The beercan is 4X more expensive than the M42 prime Jupiter 21M. Both are as fast with a f/4.0 maximum aperture. I was also expecting a lot from the beercan. I have 2 copies of the beercan an compared the best one. The result does not correspond to the hype on this zoom. The beercan is the worst lens of this match@200mm! It partially correspond to what I observed in real life shooting because I have been disapointed by the beercan many times.
An other surprise is the comparison between the Minolta 75-300 big beercan and with the D kit telezoom. They offer roundly the same results which are better than with the beercan. So at 200mm, tke kit tele-zoom is not a bad lens at all and is sharper than my 2 beercans. The Big beercan is also sharper than the beercan but I am not surprised with this point because in reel live shooting I enjoy the big beercan. I will have difficulties do decide wich 75-300 to keep!
Keep in mind for zoom lenses compared in this match is at@200mm. Do not forget to look to my other comparisons.
Keep also in mind that the purpose of this match is just to compare the sharpness, and looking a 100% crop make only sense for huge (e.g. 75cm * 50cm) prints.
