Sigma 10-20mm f/3.5 EX DC HSM Lens (Nikon F) $299 + free s/h

I'm wondering if I should get this or the Tokina 11-20mm lens F/2.8 (probably not the latest generation but last gen would be fine)

Want to do astrophotography and landscape photography. Thanks.

Would this fit a Panasonic gh4?

I have a tokina 11-16 DX. It worked fine and I liked it. I would recommend it and the the tokina brand.

I had an older full frame tokina 28-80 2.8, loved it. would not hesitate to buy another piece of tokina glass.

Not directly. I'm sure there's an adapter available

Both are fantastic; after years and years of these two being compared, I've surmised that the Tokina is the better buy.

That said, I had the Sigma way back on a D80 and the edge distortion was noticeable. Never bothered me but if you're huge on that, it's worth noting (but of course any UWA will have this) and can be worked out post-process. I did like my sigma a lot, so would not hesitate to recommend.

The other advantage of the Tok is of course the f2.8, but not important if you're shooting astro/landscape stuff since you'll likely always have your tripod.
