Re: Vivitar Series 1 70-210mm f/3.5 is actually fine on NEX-7

Yes, my firmware is up-to-date. I am using peaking as a base before using the Focus Assist enlarging functions in almost all cases.

Just to illustrate focusing difficulties in macro :

I hear you. There is a very subtle transition from focus to out-of-focus on the Vivitar, not unlike my Spiratone 135mm f/1.8, and that makes it hard to nail focus exactly. I suspect this has to do with different colors having slightly different focus planes. Film is thick enough to hide this, but sensors aren't. Oddly, it is easier to focus this on my NEX-7 than on my NEX-5.

BTW, you do have the peaking firmware update in your NEX-3, right? It helps even during magnified live view. I also like a $20 magnifying pseudo-viewfinder attachment on the rear panel for my 5.
