8-16mm:

Pros:
8mm
Good Quality

Cons:
No "gold ring" (EX)
1000$
Can't put a filter on it


10-20mm

Pros:
750$
Can have a polarizing filter
Good Quality
"Gold Ring" EX

Cons:
Not 8mm


of course the 10-20 is cheaper, SHould I be again of a not so good copy ? I dont want to return it and wait again.

Another thing is that I don't use my XTi that often.. 750$ for using it SOME times..... I don't know if its worth it, however I know that the 18-55 is poor.

The 8mm is really cool but I could only afford the 10-20. Should I wait...

Do you *really* need a filter on an ultra-wide angle like this? The EX designation doesn't seem to be worth much as there are good and bad lenses with and without it. The only difference locally is they put a longer warranty on EX ones.

If you just want to go seriously wide angle at low cost, how about the Samyang 8mm fisheye? Seems to ebay just over $300 (US or Canada). Ok, it's quite different from the Sigmas due to distortion, but still may be one to consider.

A polarizer filter is somewhat useless in most of the times & there's no comparisson to the sharpness of the 8-16mm. the tokina 11-16mm F/2.8 is sharper than the 10-20mm,has constant F/2.8 & can use filters. So it's the only alternative in terms of optics

I'm keeping a keen eye on the 8-16mm as I'm planning on buying it at some point. The 10-20mm is a great lens too and so is the Tokina 11-16mm.

However, they're rather expensive lenses and if as you say you rarely use your camera then you might find the expense hard to justify.

I really dig a polarizer on my 10-20, even though uneven polarization can occur. It doesn't bother me.

Hi,

I've looked at the Sigma 8-16mm too as it is an interesting offer. It's almost like getting a fish-eye without having to straighten out the lines and without having to keep the horizon in the middle and the verticals of the sides.

having looked through a few hundred sample shots so far - is it me or does this lens seem a little "woolly" when it comes to sharpness? A lot of the details seem fuzzy to me somehow...?

Either way a very interesting offer and if I didn't have the Tokina 11-16 already...

Cheers

The polarizing filter would be useful for car photography : it removes reflections

but 8mm is wider...

For cars photography:

10-20 + Polarizing filter

or

8-16 ?

I think the polarizing would help against reflection but then again 8mm is so cool ! However i cant put anything in the corner without major distorsion so i guess its more or a pro tool.

I think ill get the 17-85 IS after that one, but for now... ! Which ones !

You can get pretty artistic shots with the Sigma 10-20…

Id get the 8-16mm simply because its wider. Afterall, thats what you're getting an ultrawide angle for right?

Why not go all out and get the 3.5mm Sigma fisheye then?

Because that would be silly

Nice one mate, thanks for sharing!

Honestly,I for one would preffer wider range than filter usage. There were so "many" times I needed a polarizer,that I decided to sold mine.
