16-50mm has 72mm filter size (and an explanation why sometimes rumored specs do change).

We just got a confirmation that the 16-50mm f/2.8 SSM lens has 72mm filter size. But this post is more about an explanation I have to give you. Some of my trusted sources gave me slightly different specs (for example different filer size or SAM /SSM characteristics of the lens). The thing I may had to tell you more clearly is that usually Sony (like other companies) does develop a couple of slightly different prototypes. I know for example for SURE that there wee A77 camera with CF slot, A77 cameras with fixed LCD, and so on, but as you know the final A77 will have a tilting LCD and most likely no CF slot. What matters is that most of the core features are correct. I knew since almost nine months the A77 would have a 24 Megapixel sensor (and I have been the first to tell you that), since months I knew there is a 16-50mm kit lens, and so on. What changed in the meanwhile are the “minor” features (which are of course also very important).

I ask you to keep in mind that we are dealing with rumors here and not with official news. It’s not an easy job believe me, and I am learning more every day!
