| p.1 #1 · Dark circle on viewfinder EF 24mm f/2.8 + 5DII |
I'm new here
Have been searching for this topic on the forum, but couldn't find any.
Is there anyone here using EF 24mm f/2.8 on a 5D Mark II?
I recently purchased a second hand copy of this lens (just barely one month old). The guy who sold it said he found it rather not so useful on his cropper body. And i got it approximately $50 less from the new one.
Anyway, the lens is great, decent focusing speed, and very sharp wide open. Didn't find any flaw on it's performance and shot result despite a bit noisy AF (which is normal for non USM lens).
Until i noticed that on my 5D mk II's viewfinder, the lens showing me this, how do i describe this.. a very thin circle border on the center. Almost 40% of the viewfinder. And the area outside of the circle is a bit dark compared with the center. Almost like a vignetting but clearly making a perfect thin circle border. Boy, i wish i could show you what i mean.
This remind me of my 58mm Helios lens on my old Zenith SLR camera. It also has the same thin circle on the center of the viewfinder. But i think it's obvious to have it there for manual split focusing.
I hope this is normal on Canon EF old design lenses like this one. FYI it was announced by canon on 1988. Among the first EF lenses introduced during early Canon's EF mount era.
Would appreciate any info about this, sorry for the long writing
