    Great price, great optics on an ultra-wide zoom from Canon

    Love it. Was reviewing ultra-wide-angle zoom lenses for my T3i. Have always wanted something wider for landscapes and interior shots. By accident I came across a new press release on this lens from Canon. Saw the low list price on genuine OEM Canon optics and took a quick trip over to my local camera store for some hands-on impressions. A few minutes later I left with one. Have been very happy with its optical performance so far. I am not a pro shooter so the fact that is has "kit build" ...

    Good bargain

    I bought this lens for a vacation trip to New York City, using it on a 650D to complement an 18-135 STM for wide cityscapes. Subjectively the IQ feels about the same as the 18-135 STM, which should be taken to mean "not L level, but good for the price." Corner resolution is surprisingly good, although vignetting is pretty obvious. IQ appears to be better at the wide end than the tele end. IS works, AF is silent and fast. Plastic build, but no wobbles in the lens cylinder or the zoom/focus ...

Questions & Answers


Which Ultra Wide Angle?

I would like a lense with a zoom range wider than my old (and faulty) kit lense, but do not know which one to get. Do I buy a Sigma 10-20, a Tamron 10-24, or save up for something more expensive? Just looking for some advice Thanks!

No. Get something less expensive! Go for the Canon EF-S 10-18mm f4.5-5.6 IS STM. Great little lens, better than the ones you mentioned, very light and very affordable. Continue Reading

Like I said, the 10-18mm is better in IQ than the two or so (3, there are two different Sigma 10-20mm versions) lenses you mentioned. So, that is my (good) advice, just go for a new Canon EF-S 10-18mm f4.5-5.6 IS STM. Better and faster AF, better sharpness, lighter, cheaper, IS. Continue Reading

Well, very strong CA, very bad trying to focus with live view contrast detect AF. That is two faults ;) Continue Reading

Canon EF-S 10-18mm f/4.5-5.6 IS or Sigma 8-16mm f/4.5-5.6 DC?

If you have used both the Canon EF-S 10-18mm f/4.5-5.6 and the Sigma 8-16mm f/4.5-5.6 DC, which one would you recommend buying if price was not a consideration? In particular, I'm trying to understand the practical impact of the trade-off between the 10-18mm's IS functionality and lower barrel distortion vs. the 8-16mm's wider angle

ANSWERS Detailed review of both. and the class-leader the last decade Would get the Sigma or Tokina if money and weight were not an issue. But the Canon is a absolute bargain. lightweight as well. IS functionality gains little to nothing in stills images. The rule of thumb says you can already choose pretty long shutterspeeds handheld without IS. And the Tokina is 1-2 stops faster. But it can be nice when recording video. Continue Reading

Mt 2 cents. The 10-18 STM is the first UWA I feel its worth it for me to buy. The resolution, lack of distortion, price, size, and the fact you can attach a filter to it. I also think that having IS useful in some limited situations......for example I was shooting some shots of a waterfall yesterday and if I had IS I probably could have left my tripod at home and still get the effect I wanted.

Help choosing an UWA for my 7D please.

I need help choosing an UWA for my 7D. I am off to the USA at the end of July (Grand Canyon, etc. etc.) and I thought it might be nice to go with something wider than my EF-S 17-85. The choices seem to be: Canon EF-S 10-22 F3.5-4.5 Canon EF-S 10-18 (due out soon) Sigma 10-20 F3.5 (I would pay the extra for this over the 4-5.6) Tokina 11-16 F2.8 Tamron 10-24 F3.5-4.5 I think I should exclude the Tokina. It's the most expensive because it goes up to f2.8 but I don't think I need that. A few reviews of the Tamron suggest it is a bit softer than the other option so maybe I can discount that one as well. So that leaves Sigma and Canon. I suppose my initial preference would be the Canon 10-22. It already available so I would get more change to try it before going that if I waited for the new 10-18 and it has a marginally larger range than the Sigma. Does anyone have any thoughts that might help. Thanks

I'd suggest the 10-18mm.  It's already out, and many forum members here have one already.  In fact, I got mine yesterday (a day early; was supposed to be delivered today).  I've not taken any shots with it yet, but I played with it for a few minutes and was quite surprised with how fast and SILENTLY it focused. If the image quality is as good as everyone says, then it's a steal at $300. Continue Reading

Your first choice is the best one > Canon EF-S 10-22 F3.5-4.5 next lens. Hoping to get one for under $500, used / refurbed, of course. Fish Here's a couple taken with my buddies 10-22 > Continue Reading

I've loved the 10-22 for years, and made many times the cost of this lens with photos Ive taken with it. If I were buying now, I might get the 10-18, but it is  a stop slower. Don't think IS will make much difference shooting WA, but not bad to have. Continue Reading
