Rockwell reviews on adapting old lenses
Rockwell reviews on adapting old lenses
While Ken Rockwell is a fine writer and covers most techniques of using a 50 year old manual lens on a modern digital camera; I noticed glaring mistakes in biased data. Since old film stock was NOT high resolution, lens makers countered the weakness with some really high resolution lens in the center of the field. I do mean very high, add to that a awesome 12 blade aperture or more and use this old lens on a smaller than full frame chip and you are getting the ultra center specs, 2x, or 1.5x, depending; on m4/3 or aps-C. These old lenses, if there clean, are much better than modern lenses in the center resolution lines/mm. Rangefinder lenses with the short back focus being the ideal lens, or Cmt. lenses. Ken seems to ignore this optical specification entirely and remark about color shifting. Old german made Rangefinder lenses are generally blue shifted due to the Purplish coatings. Put a 85c filter on & my testing reveals photos that look like Kodachrome l slides, stunning sharpness, stunning Boken, beautiful colors, what the heck is Rockwell smoking? I see a conspiracy of reviewers favoring modern just out lenses and cameras for sales reasons, Not photo image making reasons. Regards, Don@Eastwestphoto
