Those blues are profound--I have never, in all my shooting, captured blues, with or without a polarizer, of that depth.

Keep in mind to, that I am strictly a jpeg shooter and so it is important for me to get good pictures out of the box..When shooting anything other than people I am in vibrant mode and make sure my exposer is spot on. Yes, those are straight jpegs.

So the f/3.5 HSM version has to my understanding been out for a while now. Does anyone here have it and are any good comparisons between the versions?

And please people, don't once again start talking about the old version in this thread. Thank you.

jgredline, what circular polarizer are you using. Good quality 82mm polarizers seems expensive. Should be be the thin one. Most of my polatrizers i have are b+w and i love the quality, but seems 82mm b+w polarizer runs for about $200 at amazon. Any suggestions.

I am using both the Hoya Pro1 and B+W as well. I really don't remember what I paid, but I am guessing they where in the 70 dollar range. Of course this was a few years ago and the way prices are out of control right now, who knows.

I have the 3.5 version (which is HSM on Pentax), thanks in no small part to jgredline and jewelltrail's images, and all the others in that Sigma 10-20 thread.

No direct comparison possible, but I've read and seen images showing that this new version is sharper in the corners than the old version at wider apertures, but a bit soft at 3.5 (and my experience concurs). The distortion is the same, but the new version has a lot of CA where the old one had almost none... but this CA is about the same as the Pentax 12-24.

One big difference (aside from HSM and 3.5) is that the new version has zero flare. Like, point it at the sun = none! Great job, Sigma... since we can't correct for flare in post!

The images below aren't great examples (unless you like "cold duck"), but you get the idea:

At 10mm (f8):



At 20mm (f8):

The new 3.5 Sigma has an 82mm filter thread, and they are pricey! I snagged a Marumi Super DHG polarizer (top one reviewed by lenstip here) for $86. Very low profile and thin, but obviously the polarization of skies varies a bit on a wideangle lens like this at 10mm.

Not like the OP even notices this thread, but in case anyone else is wondering, I finally got my Sigma 10-20mm f/3.5 to exhibit lens flare! Crappy shots, but it was specifically to test flare-resistance of this lens. (Oddly enough, the flare was worse in the viewfinder...)
PF isn't much, either...

@10mm, f/11




@20mm, f/11




@20mm, f/4.5

So, is there any consensus as to whether the 3.5 is "better" - except in low light, perhaps? I see that the 4 is still available...

I'm likely to get this 3.5 version. The larger aperture and quick-shift like feature in HSM makes it an easy choice for me.

I will go nuts before I decide which lens to buy. I almost wish I had a GF, who would surely say, "you want to get this lens", and "these aren't the droids we're looking for"...
