Hello all,

I was out with my grandson a week ago for T-ball practice.
I thought, what a fine time to finish a roll of film I'd started in my old 'F' and a fine time to take out the old 50-300 f4.5 AI zoom, all 20 pounds of it, or so it seems.

When the negatives and CD came back I was a bit surprised to see this shadow on all the images.

At first I thought the old 'F' was screwing up, until I got to the first shots, with a 20mm prime, and the shadow was not there. So, I concluded, it must be the 50-300 zoom.
I'll refer to it as a lazy aperture, someone may have a better term, if so is there a simple remedy?
A CLA on a lens? Who and is it worth it?
Or is this something else?

Thanks all

Joe
