next PZ Lens Test Report - Sony 28-75mm f/2.8 SAM - Klaus - 07-16-2011
Weak at f/2.8, very decent at medium apertures. Prone to centering issues it seems.

Thanks. But you already tested the Tamron, did you think the Sony version had improvements?

Well, no, I didn't expect any improvement but it was still necessary to test it. Many users just do not know that it is basically a Tamron lens,

BTW, for Sony FF, some resolution charts go up to 3600, some other to 3500. It's slightly misleading. And none has the Poor/Fair etc scale like Nikon.

That's a caching issue in your browser. They are all at 3600 now.

After refresh, they all show 3600 now, except the 28-75.
