Here is my opinion of the sharpness of the lenses I use, in sequential order. All lenses are compared by using their best f-stop. Listing is from sharpest to least sharp. 1. 75mm 2. 45mm 3. 105mm 4. 600mm 5. 200mm 6. 300mm The 45, 105, 600 and 200 are very similar in sharpness while the 75 is noticably better and the 300 is noticably worse.

The majority opinion in the Med. Format Digest group is that the 55mm is the sharpest lens made for this system.

There have also been a number of posts on the internet about the extreem sharpness of the 135mm Macro lens. I have both the 55mm and 135mm and I beleive the 135mm is the sharper lens of the two.
