A small experiment, inspired by "Chrismuc" on the MF thread.
I recently compared three lenses:
A brand new Sony Alpha 70-400/4-5.6 zoom
A 25 year old Minolta 80-200/2.8 APO
A Sonnar 150/4 for Hasselblad from the 70-ies? It's a black T* coated lens
Test was done on APS-C camera with 24 MPixels, (pitch 3.9 micron), corresponds to 54MP on full frame DSLR, so it is pretty demanding. Landscape sharpening on all.
I could make the test with a full frame camera but any difference would be less visible as there is no 54MP full frame camera.
Would you be interested, the article describing the test is here: http://echophoto.dnsalias.net/ekr/index.php/photoarticles/73-sonnar-150-cb-on-dslr-using-arax-tilt-adapter
I would be interested if anyone sees any differences?
