Sigma 10mm vs Samyang 10mm?

Other than auto-focus, does Sigma have any significant advantages over Samyang? Autofocus is not a big deal for me as I plan to use this mainly to shoot milky way photos.

Thanks.

Sigma 10mm is a fisheye lens, while Samyang 10mm is a rectilinear wide angle lens. A better comparision would be Sigma 10mm fisheye vs. Samyang 8mm fisheye.

Yeah, there is a big difference between rectilinear and fisheye. Very different rendering. I'd go for the Samyang 10mm, myself, but fisheyes have a very special look, and if you are after that, go for it. Samyang 8mm is a good fisheye, too.

anything wider than 12mm your not gonna use the auto focus much if at all (considering the scene would be more your subject than an object so you will be setting the focus for maximum hyperfocal distance), personally i would go the samyang 8mm fisheye for fun value, its build quality and its cost (also defished fisheye images hide aberrations better than rectilinear ones)

Are you talking about the sigma 10-20? The 10mm end of that is comparable to the samyang 10mm.

If you're looking for a fisheye, the Samyang 8mm rocks. It defishes *very* well, and you're not going to find anything wider than what it can offer. The Samyang 10mm gives you about 110 degrees of view. The 8mm fisheye gives you nearly 180. You have to be careful not to get your toes in the shot.

Thank you all. Did not know that Sigma 10mm was a fish eye lens. I was considering Samyang 8mm but its f3.5 compared to f2.8 for 10mm. Since my main reason for buying is shooting stars, I thought f2.8 will be much better than f3.5. Has anyone shot night skies using Samyang 8mm?

The link I posted is on a site dedicated to just that, and it's one of their favorite lenses.

There are many Astrophoto threads here, many of the photos were taken with Samyang glass. There is also a Samyang lens club thread, which has some astrophotos. Feel free to search the forums

The thing is, 8mm gives you longer exposure times before stars leave star trails. That means the difference between f3.5 and f2.8 might not be that big. But the frame will be very different! Because even though there is only 2mm difference, this is actually very noticeable, and with fisheye even more so. The stars will be smaller, the background will be smaller and look like it is more "far".
Butf or astrophotos, any of the Samyang wide angles will be good. 24mm f1.4 is good on full frame, but might be a little tight on APSC. 16mm f2, 14mm f2.8, 10mm f2.8, 8mm f3.5... all of these can be used for star photos quite well. Supporting gear will be very important, though! Stable tripod, triggers.. and of course technique. These are not always easy to focus, especially in the dark. Timer, MLU, dark frame NR, and so on.. and then post processing. I think any of the Samyang wide angle lenses is a good match and a good place to begin. You can invest in more gear once you figure out what you need - whether you need wider angle, faster aperture, fisheye or rectilinear, whatever.

Just noticed there is a Sigma 10mm fisheye for sale in the marketplace right now. Still not as affordable as the Samyang fisheye, but you might want to check it out

Thank you for all your responses. I think I will get the Samyang/Rokinon 10mm. Samyang 8mm sounds tempting with its 180 degree field of view but it also requires a me to buy plugins and involves lot of post processing.
