Additional LENS PERFORMANCE TESTS now available : LUSENET : Konica 35mm SLRs : One Thread

being inspired by Mike's lens test data, and in an effort to help mike out, i have put up the lens performance tests for a number of hexanon lenses: 28/1.8, 35/2, 40/1.8, 85/1.8, and 100/1.8. If anyone has any additional performance tests, i'd be happy to do the same. these are from popular photography: 8/78 and 9/83.

Great work!!! Keep it up!

Hi Paul, Hey, nice tests! I was just looking at those old magazines and was going to put them up too! haha. You beat me to it. They look great though!

I saw the 35mm f2.0 test and went WOW, look at the contrast on that puppy in the center, then I saw the edge and said "ouch! That is horrible!" I was a little surprised about the 85mm f1.8 at f1.8, but at f5.6 - f8 it is reall nice.

Have to study the rest and look over them. Hey, thanks for the link (I'll put a link to your page up at the Blue Book) and for the inspiring comment too. :)

Great work!!! Keep it up!

Konica Hexanon 35mm f2.0 lens qustions...

At f2.0 this lens just barely makes 20% contrast, and even at f5.6, a lowly 40% contrast. So can one assume that this lens has a real hard time differenciating between shades of gray or other colours (eg, red spectrum of light)?

This lens really repersents an awesome and a dirt poor lens at the same time and just fustrates the heck outta me.. haha.

Paul.....Thanks for posting these tests, but I can't read 'em. What's the secret? I can see them but can't get any detail. Sort of like a bad lens, if you know what I mean. Maybe somebody can help me out? blurrily...jim
