Looking for opinions of those who have owned or used both lenses. What primary differences do you find? Would it be worth selling the Sigma to get the Canon? Any other comments?

I have the Sigma 18-200 and am considering moving to the Canon, simply because its a Canon. I picked one up in the store the other day, and it feel great, and very natural on my 40D. I know the Sigma has a better build, but there is something enticing about the Canon. I can get one for about $500 here in HK if I buy in a kit with the 50D.

Thanks,
Jesse
 
Suprised that you have not got lots of replies yet. The Canon fanboy wolfpack must be sleeping.LOL. Usually whenever anyone dares to compare the two brands it stirs up a hornets nest. Seriously though, I do not think that the new Canon lens is readily available worldwide and that not enough people have got the new lens yet to do a serious comparison. I am sitting on the fence on this one until a really reputable review from someone like Photozone.de comes out before I make up my mind on which one to get. From what I have seen so far of various test shots, if I already had the Sigma, I doubt whether I would fork out the extra money for the Canon.

Good luck. I believe the Canon 80-200 started selling last week or so and not too many have them. There are several threads here with some images, though. Try a search.

Some love the Sigma, it seems. I tried one and did not, and returned it. I will probably try the Canon. No idea what I'll think of it, though.

Don't know any with both, but I have the Canon and pretty impressed (for a super zoom)

Barrel distortion at wide end is about the same as the Sigma and Tamron (correction using either profile in PTLens seems to work) with noticable CA only when wide open at 18.

The mid-tele end looks really good.

I have had mixed luck with Sigma lenses with 'variability' in the quality, so would prefer not ...

Samples have already been posted, but it's fair to say neither lense is an L (and certainly lighter than an L)

I bought the Canon 18-200 in Calgary on Friday to replace my 17-85 that I broke on holiday :(

I did some comparisons in the shop between the Canon and the Sigma and it was a very difficult decision to choose between them.

I'm certainly no expert in testing lenses (so please bear that in mind with these comments) but from limited tests I did I got the impression that Sigma's IQ was probably slightly better than the Canon. The Sigma seemed to be slightly sharper, but it's very difficult to be sure when you're just messing around in a camera shop. There's a limit to how many focal length / focussing distance apeture variations you can test.

There were however a few things I didn't like about the Sigma:
  • The OS (IS equivalent) seemed a bit "jumpy" and I didn't like the way it worked compared to Canon lenses.
  • The focus ring on the front of the Sigma is much wider than the Canon, and I found myself trying to turn the focus ring instead of the Zoom ring. That didn't happen when using the Canon.
Those 2 factors (plus the fact that I'm not a price-sensitive buyer) steered me towards the Canon. I'm a big fan of IS and use it a lot.

So far I'm happy with my purchase, but I've only had the lens for 3 days and I haven't had chance to examine my photos closely on the computer.

My overall feeling was the Sigma was better value for money, but I went for the Canon because of superior IS.

These are just my opinions. I'd like to have read some in depth reviews before purchasing the new lens, but I needed to buy there & then.
 
I would guess that the Sigma is every bit as good as the Canon, optically.
The OS vs IS has been said to be about equal.

The Sigma is probably the best bang for the buck, but my experience with AF-issues with Sigma is bad so I went for the Canon, love it, and it´s probably better where the Sigma´s weak spots are, and vice versa.

I still have Sigma-lenses that I like, just not all Sigmas deliver. (17-70 50-150 etc.)
If you have a Sigma that focusses where you point it, keep it!

Kind regards
Mike

Very nice gallery, Larry. Two questions:
o Where did you buy the lens? If locally, I'd like to know where.
o What breed is the tiny puppy?

BTW -- I had the Sigma 18-200 OS for a while but some of the mid focal range shots just didn't look quite right. And on some the bokeh was not very pleasing. I definitely want to try the Canon version -- and I'll be in Joshua Tree this weekend.

I have the Sigma 18-200 OS and are very happy with it. Do not know the new Canon. The Sigma has its weaknesses, but I am sure the Canon has them, too.
I think this is what you have to ask yourself:

Does the Sigma do what you want it to do, are you happy with the performance of the lens and the handling? If the answer is no, you should have a look at the Canon and see if it works better for you.

If the answer is yes, you need to decide if it is worth the money to you to have the Canon brand product.

On another line, you said your are looking at buying this lens in a kit with a 50D. I am also thinking about getting a 50D, can you give me an idea of the price for the 50D body in HK?

I bought the lens at Samy's in Pasadena, Ca. as a kit with the 50D.

The pup is a Cairn Terrier (Toto from the Wizard of Oz) we bought about 2.5 weeks ago. We named her Tilly. Our older dog, Jack has no interest in playing with our 3 year old Scottish Terrier, Mitzi, so we bought Tilly as a companion and playmate for Mitzi. She is a marvelous dog, full of personality and very smart. My wife and I both prefer small terriers (no yorkies)

For a superzoom these look pretty good. Would have been nice to see some that had CA correction applied because now the corner sharpness is being affected by the mostly red/green CA.

Thanks, Larry. Not an option I want to take, since I have a 40D now.

My first dog, long ago as a lad, was a Scottie (Sir Heather McTavish); I was a year younger than he was. Second, many years later, was a Westie and third was a Cairn. Just now we're between dogs: They inhibit travel for us. Terriers can be terrors -- but they are great!

Well, sharpness seems comparable from the pics I've seen so far. There is certainly some CA on the 18-200 under certain circumstances, but then you also get that on the 17-85.

I'm quite impressed with the sharpness at 200mm. There is noticable corner darkness at f5.6 @ 200mm, but then the Sigma only does f6.3 @ 200mm.

One camera shop in Calgary advised me that the 18-200 is soft at 18mm, but my copy doesn't seem too bad.

Here are some samples shot at 18mm:









 
LOL Larry I noticed the photos from LA ZOO

everytime I get a new camera or a new lens (which seems to be too often for my wife's taste) I also take it to LA Zoo to try out. Shots look very good, but I am still holding on for Tamron 18-270 vs Canon 18-200 comparison. $100 difference makes a big difference to me these days
