Are there any huge problems with this lens that would dissuade you from getting it? I want to replace my 28-105 3.5-4.5 II with a fixed aperture, fast zoom, and I browsed through the archive for the Sigma 24-70 2.8 and I must say, I LIKE what I see.

On top of that, it's SO CHEAP in Hong Kong, where I'll be this Christmas. It retails for like, $370 new. Way cheaper than the L equivalent, and even cheaper than the Tamron 28-75 2.8, which I don't want because I'd rather have the 4mm on the wide end, and I also love SIgma's build quality.

How bad are the flare issues etc...? Or should I go for it? I realise it's not USM but it just seems like such a great deal. This just looks like one hell of a lens for a hell of a price!

How fast and accurate is the AF?

I'm gonna get my hands on this lens this christmas, test it out, and if I like what I see and the price is really as cheap in HK as I'm told, I think the 28-105 is getting replaced!

Anybody got any alternatives to suggest? The only one I'm looking at is the Tamron 17-50, but I like a bit more reach in my walkaround lenses and want to upgrade to a 5D at some point. I'll also be picking up a 70-300 IS first this Christmas, so I'd like the 50-70mm gap filled.

in good light, the AF is real fast and accurate. in low light, it has some trouble. but i've tried two different L versions and i wouldn't say focusing is far apart. i think sigma can get annoying with misfocuses since it's motor is relatively noisy and it'll just keep buzzing while trying to focus. i've had mine a few months and i love it! sometimes though i wish it were wider but hey, that's another excuse to get a wider lens :) hehe :)

some people seem to really love the tamron version but i've never tried it so i cant comment on that. although you did say you want the extra 4mm reach. still, i think you should try it to see for yourself.

other alternatives? i think the tamron is pretty much it. or least that's the only one i considered when choosing.

with regard to the 24-70 vs 17-50. the wide side difference is HUGE.

in terms of flare, i only really get flare if i have the UV filter on. when i take it out, it goes away.

Good to hear that the AF is fast and accurate - is it really that noisy? Is it noisy enough to be a problem in certain situations (e.g. wedding, piano recital?).

I don't feel a need for the Tamron, as I have the Sigma 10-20, so I have the wide end covered. I found the focal length of the 18-55 kit lens (before I sold it) to not have enough reach for my style of shooting; that, and the desire to upgrade to full frame, dissuade me from the Tamron.

I got mine used for $300 here on potn. it's a great lens for the price. I use it for low lighting and some pj work that I do for my school paper. it is a bit noisy and I tend to just stick it on manual focus for those times when I shouldn't be noisy. so with a wedding and piano recital it might be a bit loud but if you can manual focus then go for it. I tend to stay away from that as much as possible cause I'm fairly blind :-P

I've loved mine on my 20D and my old 350D. Great lens for sure.

i actually dont think it's THAT noisy. it probably just seems noisy to the photographer since it's pretty much on your face. people around you might hear it but i've never been given nasty looks while using it even for candid stuff. although i've never shot a wedding in my entire life. hehe
but i've shot lots of candids with friends and they didnt seem to notice. i've also shot some semi quiet ceremonies like confirmations and never had problems with the noice.

Sweet. I like that it's lighter than the brick.

How does that AF/MF clutch work? There are two autofocus switches right? So is the idea to switch the clutch when you want to do the equivalent of FTM focusing? Is grabbing the focus ring a bad idea during autofocusing? I've heard mixed reports about that with this lens, some saying it doesn't rotate and so isn't affected by being grabbed, and others saying that grabbing it messes up the motors.

Also...is that a DOF scale I see on it?! :eek:

I would agree. It's noisier than the kit lens and certainly more noticable with the canon USM, but it doesn't really bother me. It's only by comparison that the term "noisy" comes into play. I've never had anyone comment on it or even give me a strange look, and I have shot a few pics during ceremony at weddings when it was pretty darn quiet. The only people that really comment on the noise factor are people in forums like these.

It's a great lens for the money. Plenty sharp. The only thing on the negative side I would mention is that the front element is so big that the filters (CP for example) are really expensive if you have that type of thing in mind to go along with it. And, if you try to use the pop up flash w/ this lens it will cast a shadow on the wide end. I typically try to go off camera w/ the flash anyway or stick a flash up top and it's not a big deal to me.. but might be for the pop-up flash user.

This is a very good lens at a very low price compared with the Canon version. The only thing is, on APS-C sensor, it is not very wide. This is probably not an issue for you since you already have an ultra-wide lens.

Please note that Sigma4less.com also sells this lens for $370, plus shipping. You may want to consider that option you will get the US warrantee this way (assuming you are in US).

The filter thing is annoying, but isn't a deal-breaker. I also like to take my lighting off-camera, I never use the pop-up flash, so that isn't a problem. The shadows from the pop-up flash with the Sigma 10-20 are hilarious!

Thanks for that info, but I'm in Canada and I live in Hong Kong, so I can live without a US warranty, hehe.

Great lens. Only thing is the lens has difficulty in focussing against strong back light, same with the sigma 17-70, where even the kit lens performs better.

oh yeah. that's a problems re: filters and pop up flash. but i wouldnt call it a deal breaker. with the pop up flash, you'd probably have to be around 30mm so that the lens wouldnt cast a shadow.

about the manual focusing. there's no FTM on this lens. there's the usual AF/MF switch. you do that first. then slide the focus ring down (toward you) then focus :) i think it sounds more complicated than it seems. i remember thinking that it sounded like a hassle before i got the lens. but really once you've used it, it's not a hassle. maybe if you're used to FTM it'll be awkward at first but it's really no biggie :)

and yes that's a DOF scale :)
