Sigma 20 200mm f 3 5 6 3 dg contemporary vs tamron 28 200mm f 2 8 5 6?

I don't have a page on the Tamron 28-200mm f/2.8-5.6 on this site, so I can't compare its specs fairly. I'd rather not guess at them.

Here's what I can tell you about the Sigma 20-200mm f/3.5-6.3 DG Contemporary. It's a full-frame 10x travel zoom that starts at 20mm, made for Sony E and L-Mount, with autofocus but no stabilisation. It gets darker as you zoom in, which matters in dim light. Its full page lists every body it fits.

If you're weighing the Tamron, check that it fits your mount and supports your camera's autofocus. The lenses guide explains why the wider aperture at the long end matters.
