Canon EF-S 10-22mm f/3.5-4.5 USM

EF10-22
Review Date: Nov 5, 2007 Recommend? yes | Price paid: $700.00 | Rating: 10 

 
Pros: Range, sharpness, low distortion, quality, focus, range.
Cons:
I can't think of any.

I really like this lens.
I first purchased the Sigma 10-20mm, it was less expensive, and though it was sharp, the distortion at the wide end was so bad it wasn't that fun to use the lens. Following a trip to Thailand and trying to correct distortion on shots of the numerous temples and beautiful buildings, I deterermined to sell it. But shortly after selling it I missed the ultra-wide angle aspect, so I ponied up the money and bought the Canon. I am very, very happy with this lens, it's sharp, and though there is some distortion at the wide end (mostly gone by 14mm), it's easily corrected.
My wife and I travel some, so for shooting landscapes and buildings it's perfect. The bonus is its ability to shoot indoors under low-light.
I really like this lens.


 
Canon EF 24-105mm f/4L IS USM

Review Date: Nov 5, 2007 Recommend? yes | Price paid: $1,050.00 | Rating: 10 

 
Pros: Sharpness, color, contrast, range, better IS, and fast, accurate focusing.
Cons:
Initially soft, I sent it to Canon who indicated there was a lens element out of alignment.

I bought this to replace my very good copy of the 28-135mm IS, and was initially unhappy the 24-105mm wasn't as sharp. After the fix all was right. I'm happy with the range at the wide end (my complaint with the 24-135) and it's sufficient at the long end for my needs. This coupled with my 10-22mm covers nearly all my normal shooting needs--and I have a 100-300mm for additional, and rarely used, reach.
I also like the heft and build quality, and am very happy with resulting images from this lens, I have less PS work to do. Other than landscape shooting, this lens is on my camera 90% of the time and overall I am very happy with this lens.


 
Sigma 10-20mm F4-5.6 EX DC HSM

Pros: Solid build, quick & quiet focus, DOF, good sharpness, Sigma service
Cons:
Distortion at wide end, soft and de-centered at first, Sigma QC.

I would rate this 9 overall, except my copy at first produced soft images and had the infamous de-centered issue, I had to send it twice to Sigma for correction; once the softness issue was resolved, the de-centering became evident To Sigma's credit, the turn around time was about two weeks both times and they fixed the problems.
That said I think this is a very good WA lens, though I rarely use this lens, I just returned from a Thailand/Hong Kong trip and took numerous pictures with it. It performed very well, the group I was with was jealous of my ability to get such wide shots in a frame. Sharpness is good, wide open, but better stopped down, then made better yet with a little USM in Photoshop.
The DOF is really the strong point of this lens, most of my pictures were taken at f8 with manual focus set at 3', the images are in focus from front to back.
It's versatile and easy to use, my only complaint is the (expected) distortion at 10mm, I guess there are shooting perspectives that can diminish that, I just don't know how to do it.
Great lens, highly recommended.

Review Date: Mar 27, 2006 Recommend? yes | Price paid: Not Indicated | Rating: 9 

 
Pros: Sharp, nice colors, fast & quiet USM, good range, IS.
Cons:
Zoom is not that smooth, IS is just okay.

I sold the Sigma 18-125mm that I purchase originally with my XT and bought this used here.
Compared to the Sigma it focuses more quickly and much quieter, it is sharper and has better colors. I'm quite happy with the sharpness and colors and very happy with focusing speed and accuracy. The IS is just okay, I've not yet seen a significant advantage to it.
At a family gathering over the weekend a son and daughter took a bunch of indoor shots of family and friends. Most were keepers, some needed little, if any, post processing, the rest didn't need much, and in the mix they got some beautiful portraits of family (especially children). Also this past weekend, used it on a ski day with my 3 1/2 year old grandaughter, her mom got some great outdoors shots with it. It is shaping up to be a very versatile lens.
Great walk around lens, however, I've missed the extra 10mm on the wide end a few times so far.
Recommended.


 
Sigma 100-300mm f4 EX IF HSM APO

Review Date: Feb 6, 2006 Recommend? yes | Price paid: $760.00 | Rating: 10 

 
Pros: Great build quality, fast, quiet autofocus, sharp, sharp, sharp!
Cons:
Heavy-ish.

My first "pro" lens and I am extremely happy with it. I've not shot a lot of pictures, but a fairly good variety of them and this lens is very sharp. I was looking at the Canon 20-200mm f4/L and I'm satisfied I made the correct decision, same money with an additional 100mm of reach.
Terrific lens, very high quality in look and feel.
Did I mention it is sharp?
