A Good Wide Angle Lens

3 July 2005

This lens seems to perform well and I have attached it to a Rebel 350 XT. Pictures so far look great. Really wide angle, possibly more than I really need, but it's fun to have. I am sure that a Canon lens is better, but would cost 2 to 3 times as much. The only problem I have had so far is at the widest angle indoors, the lens will cause a shadow when you use the flash on the camera.

Tamron 11-18

10 November 2006

I did a lot of research prior to buying this lens....comparing it to other wide angles etc. It got good ratings and I agree. I use it with my Canon 20D and it performs well. Pics are clean with no major noticable abberations. You can get a somewhat cool "fisheye" effect at the low end without having to buy an expensive fisheye lens. Use a lens hood because there is the potential for a lot of flare typical for this lens class. For the pro-sumer like me....it does the job at a lower price than it's competitors. Amazon was fine.....best price with no problems with shipping etc/.

So-so performance from an (relatively) expensive lens

12 October 2006

I've been playing with this lens attached to my EOS 400D for couple of weeks now and I'm affraid it's not living up to my expectations, or it's relatively high price. Out of all the third party contenders (Tamron, Sigma & Tokina), this one is the most expensive, about $100 more than Tokina, yet it has the most limited zoom range, but most importantly, it's way too soft. Maybe I just have a bad copy, but in that case, for the price the QC should be better. At 18mm, it's marginally better than the 18-55 Canon kit lens, but then again, I don't need it for 18mm. Color rendition is OK and with some post-processing it makes acceptable 8x10 prints, but I just can't get over the price difference, so I'm returning it and trying my luck with Tokina 12-24...

I like it

2 February 2008

I'm not sure how I would rate the value if I had to pay the normal retail price for this lens, but I got a used one for $350 and I consider it a terrific value. Get consistently good shots with it, even at 11mm using a polarizer -- much less vignetting than I expected. The lens is really small and light for something of this sort.

Not bad, could be better

26 August 2008

Pros: It's really cool what you can do with this lens. The special effects at close range are very intriguing, and for capturing landscapes, home interiors, etc. it really does the job well. For that reason, it's very handy to have.
Cons: On my Canon 30D, the lens is not quite as sharp as my kit lens (28-135mm). It's not bad, especially on a tripod, but it could be better. I also get some purple fringes on back-lit edges. There seems to be a lot of contrast, making it hard to get the right exposure - pictures tend to be very overexposed and underexposed in a single shot. These problems can be remedied with software, and the ability to do what it does makes up for the disadvantages somewhat, but you do notice the quality difference.

All in all, I like using the lens. I'm glad I have it because of what I can do with it. Make no mistake, the quality isn't as good as my Canon lens, and if I had a higher budget, I might try something else.

Pretty Nice Lens

26 August 2007

I do real estate photography and the 11 - 18 is essential for interior work. I've been using the lens for about 2 years now and like it pretty well. The major problem I have with it is color fringing along lines of high contrast. The lens also suffers from some minor fisheye distortion in the 11 - 13 range, but it is easily remedied in the digital darkroom. It has less distortion in the 14 - 18 range than my Nikkor 18 - 70 does at 18. It is not a good choice for people photography. I consider it a good value for the money.

Wonderful but for Special Occasions

26 June 2007

This is not a lens you will use often but when the situation demands it, you can get great photos in a narrow space. I can't imagine a Nikon lens would do any better. My pictures have been sharp with no distortion.

Wide Angle Lens
