i finally have enough money to buy the Canon 70-200 f/4L. now. do i go with a Sigma 70-200 f/2.8, for just 100 more?! or should i go ahead and get the Canon?:dunno read many reviews on the sigma and people say its sharp as a tack. is the 2.8 really that much better for what i'll be shooting?? (football games, portraits outside, some wildlife)
thanks guys:thumb

My thought is the difference between 2.8 and 4 is pretty large, that is an important stop. I would keep checking the reviews.

i know. what i'm asking is, is the 200 or so dollars really worth it? and should i go for the sigma. because as always i could just sell it and buy a Canon later.
any thoughts?:dunno

Daniel,
I have an older Sigma f2.8 that isn't very compatible with Canon digital SLRs, but when it's good, it's very good.
I suggest you get the Sigma if you plan to do any night shooting. The extra f stop helps with shutter speed and stop-action.
Good luck and let us know what you do.

Go for the sigma my friend. If you can go from f4.0 to f2.8 for $100 bucks I'd jump on that. I have a Sigma lens and a Sigma flash. Top notch! Love them both.

the newer Sigma's have none of the problems Ziggy was referring to. The Sigma 70-200 f/2.8 is an awesome lens. Not as good as the Canon 70-200 f/2.8, but at less than half the price, its a virtual bargain. I opted for the longer reach of the 100-300 f/4 Sigma, and its been one of my favorite lenses. I don't shoot much in low light with it, but I do know that faster aperture is always better.
:nod
Sigma's hold their value well enough that you can sell it when you're ready to upgrade to the fast Canon L w/IS.

Personally, I would go for the sigma 2.8 lens instead. Its a stop faster, uses good glass (obviously not quite as good as the fluorite in the L lens from canon) but none the less is a stellar performer. the color fringes between these two lenses is virtually indistinguishable unless you are using the 16 megapixel monster from canon. i've tried these lenses on my 20D and loved the results.
In favor of Sigma: Stop faster, faster shutter speeds possible
In favor of Canon: fluorite element eliminates all fringes and color abberations

I own the Canon 70-200L f/4 & 2.8L IS and my son has the Sigma 70-200 f/2.8 HSM. The Sigma 70-200 f/2.8 easily holds its own against the Canon lenses. This is one of Sigmas sleeper lenses.
I have had no problems with the lens on any of my Canon cameras be it film or digital.

Do you understand that "one stop" means "twice the light gathering ability"? When you are shooting sports that extra stop can indeed come in handy.
I have the Sigma -- love it!
BTW, in addition to "low light" -- you have the nice "narrow dof" of f2.8 which helps separate your subject from the background (blurs the background).
In favor of the Canon? Smaller size, $100 cheaper. Not better photos (not that lens anyway). The Sigma is one heavy piece of glass. Worth it, IMO.

I really would go with the sigma. but right now. i REALLY need extra reach right now... so i'm going with the Canon for now. and maybe when i work up 200 or so. i'll sell the Canon and buy up a Sigma. but ya never know:dunno

I had thought about going for the Sigma, but decided not to....didn't have the money.
I would say wait until you have enough money for either of the lenses and THEN decide. Otherwise you will be stressing about something that you don't have the money for.

I have the Canon and absolutely love it. Sharp even wide open at f/4. I've heard the Sigma is a little soft at f/2.8 (though at least it has it available). You can do a search on "canon sigma 70-200" and come up with a number of reviews including some sample images shot from both lenses.
The conclusion seems to be that image quality between the two is so close as to be negligible. The Canon is supposed to be a hair better on focus speed, accuracy and noise, though again the difference is pretty negligible. It comes down to whether you need the extra stop at the expense of having a large, heavy, and slightly more expensive lens. The Sigma is considerably heavier and larger than the Canon, which means it'll be less comfortable to carry for extended periods and more difficult to handhold. But if you're shooting lots of low light or high action shots, the extra stop may be the difference between getting the shot or not.
One other note, I know nothing of Sigma's customer service, but I had to send the Canon in to get recalibrated (it was backfocusing slightly). They were prompt, courteous, and repaired the lens quickly at no charge. Not solely a reason to buy Canon, but a consideration nonetheless.

graeme, I've had my eye on Sigma's 80-400 OS lens and have heard terrific things about it. As soon as I have an extra $1000 laying around (which means not in the near future), I'll pick one up as it seems like a no-brainer against the more expensive Canon 100-400 competitor. It's great to see Sigma integrating OS into it's lenses (and doing it well, from what I've heard) and it'll be nice to see them extending that feature to a broader selection.

when i was making my 70-200 purchase i had to go through a similar process. i knew i wouldn't be happy with the f4.0 and i just wasn't comfortable with going 3rd party at the time. i wanted to feel what every "L" lens owner feels, knowing that in your hand, you have the best lens you can get. i managed to get the cash for the canon 70-200 f2.8L and it was worth every little penny, it has such a great feel and the pictures are stunning. it's the second best equipment purchase i've made - the best is my tamron 28-75 f2.8, that thing is just incredible and a complete steal.
in my opinion, i haven't tried the sigma, you should keep saving up for the canon 70-200 2.8L, it really is that good. you're 14, you should take some time to learn how to use all of your equipment some more before you make that leap.
i hope that helps

I own the Sigma 70-200 and it is by far my favorite lens. Absolutely incredible. I do have to point out though that im a little sigma biased as I shoot with an SD9 and can only shoot sigma lenses, but I do have to say it has never ever let me down. I bought mine used off ebay a year and a half ago, there may be one on there you could get for a steal. Dont be afraid of going "third party" as someone earlier said. Sigma lenses and equipment are top notch. Im sure L would be the best overall for you if price was no issue, but for the price you cant beat sigma lenses.

My Sigma 70-200 f2.8 with 1.4 TC came in last Friday and I've been playing with it all weekend - great lens :thumb
It is heavy though. I look at it like this, as I was going through the same debate you are:
vs. the Canon 70-200mm f4L it gives you the extra low light and stopping ability and really isn't "that much more". The f4L is much lighter in weight, if that is a consideration to you.
vs. the Canon 70-200mm f2.8L it is a little bit less and not as "screaming" (my term for white lenses) when out in public. For the same price you can pick up a teleconverter for the Sigma.......and dinner.
vs. the Canon 70-200mm f2.8L IS is IS really worth almost $1000 more?
vs. the Canon non-L's 70-300mm don't even kid yourself.

Jan-09-2006, 07:19 PM
I have always stuck with the "L" series lenses. I know that sometimes money is the deciding point even at the sacrifice of quality. IF you are shooting sports, indoor, and/or at night, you will need the 2.8. A 2.8 lens will usually make the difference between a good picture and an awesome picture. Save and wait.

It's great to see Sigma integrating OS into it's lenses (and doing it well, from what I've heard) and it'll be nice to see them extending that feature to a broader selection.
I'm taking this thread off to a side road for a minute.
I have the Sigma 80-400os. I have read reviews that say it's the best thing
ever. Well, after owning it for a year, I'm not so sure. On still objects, it can
hold its own. On moving things, (BIF) it can be a challenge. The Canon L
has the USM, the Sigma does not. Yes, it makes a difference.
The other thing that I have read about this lens is that it is sharp wide open.
Mine isn't. I shoot at F8, period. I've tried wide open, it isn't good. Maybe
it just my lens, and not all of them.
My shots with this lens are here: http://www.pbase.com/davev/sigma
Now, back to Daniel.
The Canon L lens will hold it's value better than the Sigma.
The 70-200L F4 is a very good lens. I had one and sold it for $20 less
than what I bought it for. If I were to sell my $1000 Sigma lens, I'm sure that
I'm going to lose 150 to 200 dollars.
Get the Canon F4. You will be amazed at how good it is.
P.S. I have a Tokina 400 F5.6 prime. I don't know how this worked on a
film camera, but on my digitals, it is the worst lens ever. It focuses fast,
the pics are fairly sharp wide open, But the CA or Purple Fringe or whatever
you want to call it, is horrible. It dominates the photo.
Stay away from at least this Tokina.
marsmark
Jan-09-2006, 09:29 PM
I went through this decision about 6 months ago. Compared the Canon 70-200 f4L and f2.8L (tested IS too, but that was out immediately on cost), the Sigma 70-200 f2.8, and the Tokina ATX 828 80-200.
The Tokina came well recommended, but exhibited horrible purple fringing - even on areas with only average brightness and contrast.
The Sigma compared very favorably to the Canons. I couldn't tell the difference between the Canon f4L and the Sigma f2.8. The Canon 2.8L wasn't really any sharper, but I think there was a slight improvement in image brightness (barely).
In the end, I really wanted the extra stop of the 2.8, but couldn't justify the extra $$ for the Canon, so I went with the Sigma. I've been quite happy with it. Other than weight, which has already been mentioned, the only drawback I've experienced really has to do with the 2x teleconverter I bought with it (Sigma). Wide open, the shots come out somewhat soft. Still not bad, though.

I just got the Sigma 70-200mm, f2.8 yesterday and it looks like a keeper. I didn't have time to really run it through its paces, but my immediate perception is that with just the center focus dot, on a Canon XT, the focus is fast and accurate and the sharpness at f2.8 is what I would expect from a lens of this caliber, very very nice.
The lens also seems to work well with E-TTL flash, which is not the case with other of my lenses.

If I'm not mistaken, Sigma released an HSM version of their f/2.8 lens. If that is the case, then go for the Sigma. One stop faster, maintains super fast focussing and like some people said, is less "noisy" because of its white exterior.

I repeated the test 4 times to make sure it wasn't camera shake or something. The problem is repeatable and seems related to the lens. I am so disappointed, because I had such high hopes. I'm afraid this second lens must go back, and I'm running out of time for a project.
I think I'm going to have to ask for my money back, and go with the Canon 70-200mm, F2.8L. It's quite a bit more money, but I'll bet quality is not as much a problem.

Looks like the new lens has motion blur to me. Were you using a tripod? Remote release? Hand held and if so what was the shutter speed?
I'd try again on a tripod and with a remote release to make sure you aren't causing this issue.

Feb-02-2006, 04:37 PM
Mike,
Thanks, but yes, I always use a tripod for tests and a fairly fast shutter speed. I used ISO 200 for these shots. It would appear that this is an example of mis-aligned internal elements and/or internal reflections. The full settings:

I spoke to Sigma4Less yesterday and today and they will allow me to upgrade to the Canon 70-200mm, f2.8L, for a very competitive price. I really like working with these folks.

Ziggy, how did your final exchange go? You put a little fear in me about my own Sigma 70-200/2.8 lens, so I went out and tested it. Tripod, remote release, 100% crop:
200mm

70mm

Photos are noisy as heck, that's the one detail I forgot, to actually expose correctly. Duh! But still, you can see the 200mm is pretty good, like your examples from your original lens. However, a bit soft at 70mm. I think I've read in other places that the short end isn't this lens' strong point, but was curious to hear if you had comments as well based on your old Sigma.

Erik,
Try a test atf2.8 (it looks like you used f16). The problem appears mostly when wide-open and is more pronounced off-axis.
I need a lens that works at f2.8 for night and indoor sports, and for events, where I need to work from a distance, with and without flash.
It may be just a bad "batch", because the old lens, from Sigma, works so well wide open, and other folks don't seem to experience the problem.
Just to explain about the old lens, it does have problems with the dRebel XT, namely:
It occasionally locks up the camera, but no error shows.
It has a problem with autofocus in near-to-far focussing situations.
It does not work at any other f-stop than f2.8, and locks the camera with an error when tried.
I did check with Sigma, and the lens is too old to re-chip. Oh well.
To be clear, this hasn't turned me off to Sigma lenses. My 18-50mm, f2.8 is a splendid lens and super value, and I don't intend to replace it, ever. (... Unless it fails, or starts calling me names, or something. :): )
Best,

man...all you guys did is confuse me more. I am in the same situation...I am really interested in that sigma lens vs the canon.

well.
Until they are able to afford the 70-200 f/2.8L IS :thumb
Honestly, I can't see *any* reason to buy the non-IS Canon, or the 70-200 f/4L Canon. Yes, the Sigma, in my opinion is that good. Of course, I base that on my own experience with an older Sigma that has the unmitigated audacity to trounce every other lens I own that isn't a prime at f/2.8!
So, if the Canon 70-200 f/2.8L IS is out of reach, have no fear, save some cash and pickup the Sigma.

I ended up going with the Canon 70-200 f/4L. From what i've seen it just delivers great out of the camera contrast and clearity to pictures...:thumb
also, it would seem i'm a bit of a Brand whore:rolleyes

Go for the sigma my friend. If you can go from f4.0 to f2.8 for $100 bucks I'd jump on that. I have a Sigma lens and a Sigma flash. Top notch! Love them both.

If you are talking about the difference in performance between these 3 lenses, it's pretty much splitting hairs. Despite the issues Ziggy is having with his Sigma, I've got nothing but great results from mine. Yeah, I'd like to have the ISL, if just for the sealing and the occassional benefit of IS. But, for a mid $700 lens, the Sigma really does ROCK :D

Steve,
Your images look great! You got a good copy of that lens.
FWIW, I do like the look of fleshtones better with the Sigma glass than the Canon "L", but the Canon I have, the non-IS version, is just awesome in terms of sharpness and acuity and focus speed.
It did hurt a lot to part with the extra money for the Canon. :cry
Best,

i finally have enough money to buy the Canon 70-200 f/4L. now. do i go with a Sigma 70-200 f/2.8, for just 100 more?! or should i go ahead and get the Canon?:dunno read many reviews on the sigma and people say its sharp as a tack. is the 2.8 really that much better for what i'll be shooting?? (football games, portraits outside, some wildlife)
Daniel
If you plan to shoot nighttime sports the F4 is useless. Get the Sigma.
