....I look at this and begin smiling as I think the bird might be thinking (birds do think don't they), "gosh I hope that one on the other side stays there, really don't need that kind poking around over here."

It's fun, I need a smile about now.

The cleaned up image certainly looks better. From Zig's comments perhaps the problem is with the 135mm f2.8 lenses. I noticed that my 135mm lenses produce real bad CA/PF at wider apertures. But, what's the purpose of buying a faster lens if in the end it needs to be stopped down?

That seems to be a common problem with old glass.

Well, some. I have a Chinon 50mm f1.7 and a Canon FD 50mm f1.4 and neither produces any PF/CA at the widest aperture.

That was a good one Bob, I had to go back and look at the picture, and then I got it. Very clever!

Nicely done John, thanks for taking the time.
In your honour I'll hang it entitled:
"Woodpecker Contemplates Screwpoint"
Not Woody hides from his sister, Bob.. They are funny critters, they have to make motions as if they're looking for insects, before diving into the suet.

I wasn't being fair to the lens, or to you guys, the other night when I shot and published those 3 pics. I think any lens on the E500 in low light shot at 400 ISO (almost typed 'ASA' there) would have exhibited 'noise". Nice to know it can be cleaned up that well.

I didn't have time to play in daylight today but I've just shot another of the guitar that showed the lens in a better light, so to speak. I used.... the flash.....wonders...

The original guitar shot was shot at 1/13 @ f1.4 and 400 ISO
This was shot with flash at 160 @ f1.28 and 100 ISO. Full frame no PP
Then a 100% crop. Focussed on the strings you can see the DOF ( Or lack thereof)
They look respectably sharp and relatively noise free.
If I get time tomorrow I'll try the lens in daylight.

Yeah, I should have qualified it by saying old telephoto glass seems to have that problem.
