This field-test is, as the others I have published here, absolutely subjective, empirical and lacking any scientific basis. Since I couldn’t find anything interesting to photograph I decided to take pictures more focused on showing the lens features rather than creative or interesting subjects.This is why each photo was taken wide open and at F8. Moreover, to make a comparison possible, I also shot some of the mannequins featured in the Zeiss Biogon and Minolta 35mm lenses posts. Finally, as far as post-production is concerned, I used the RGB curves to set the black and grey tones, and tweaked micro-contrast.
