FactoryResolution r.jpg

Compilation of minimum service resolving power from service manuals published by Minolta and Sony.
Note the inclusion of standards out to the horizontal edge of full frame on many lenses.
All readings use the same projected target with identical equipment used since 1985 or before.
Readings less than these standards require further adjustment, replacement of parts or rejection of the lens.

All readings are taken with the center reaching maximum resolution without refocusing the edge and with the lens wide open.




other sizes: small medium large original auto

Hello Pete,
thank you for this excellent summary. Do you have any new lenses to add to this list?
For me it is very interesting to see, that the Sony versions of some Minolta lenses have a much better min. resolving power than their Minolta pedants.

Thank you!
Regards, Wolfram
