yeah, I realized that after I posted. I'm surprised that the large B300 for
the IS 3000 would vignette, since it is a 55mm thread, and using it on a 49mm
thread lens would seem to leave plenty of radial space for full aperture.
Dang. I was really hoping for a neat-o 85mm/f1.4! (50mm+B300)
Is the vignetting at all apertures or just wide open??
Oh well, the A200 is smaller. I'll just use it on my 100/2.8 for a nice 150/
2.8.
