Got it. I just don't understand how if it only how it only has 20% remaining light that it's not dark as anything. If you say it's normal I'm glad. Just not used to seeing those.nicopol said:brianleighty said:I never see vignetting charts but is it just me or does that look like really bad vignetting?
nope. quite normal for that aperture and angle.
20% remaining light at the outer corner means vignetting a little more than f2. thats the same as canons 35L and Nikons 35G.
Also...except for a few photogs with special demands vignetting is nothing to ever be concerned about.
I'm a bit of a noob...why would you want a focus limiter at all? What does that do for you?ddl said:On POTN there have been a few 120-300OS failures dealing with the OS and AF systems so that's likely where the upgrades are plus the focus limiter switch.

It is a cosmetic and software upgrade as all new sigma lenses will be able to be connected to a dock to "modify" their settings. One example he gives is that the AF can be modified to be faster or slower with compromises at each end.
