Tamron 28 200mm f 2 8 5 6 di iii rxd vs tamron 25 200mm f 2 8 5 6?

The 25-200mm G2 is the second generation of the 28-200mm, and it starts at 25mm, a little wider at the short end. Our page for it is brief, so I can't give you its full specs or camera list yet. The Tamron 28-200mm f/2.8-5.6 Di III RXD page is the one I can fully stand behind. It's a full-frame travel zoom for Sony E, with autofocus, no stabilisation, and an aperture that narrows from f/2.8 to f/5.6 as you zoom. On APS-C it frames like 42-300mm.

If you shoot full frame and want a travel zoom with a complete spec sheet to check, start with the 28-200mm. If that extra 3mm at the wide end matters to you, look at the G2 page and compare it against the 28-200mm's details. For how the f-number affects light and blur, see the Lenses guide.
