This is for Dan Fromm who said in another thread: "The ancient lenses that really aren't up to modern ones are wide angles and telephotos. There's been great progress in those types, much less in lenses of normal construction." Perhaps this is true in his experience - I know he has had a lot of it! But, I have one old wide angle that never ceases to amaze me. It is a tiny 75mm S-M Perigraphe with wheel stops, which I guess qualifies it for ancient. I use it on a 4x5 Speed Graphic. Here's a shot taken in the desert near Tucson. True, there is a little flare from the sun rising over the mountains in the background but, it is multiUNcoated and thus would not be expected to be totally free from this. What is amazing is that it covers 4x5 without a whimper. The corners are as solid as the center. Of course, this little scan isn't going to really show what it can do, but it will give you the idea.
