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

Review Date: May 13, 2011 Recommend? yes | Price paid: Not Indicated | Rating: 10 

Pros: image quality, great colour, contrast and sharpness, small, lightweight, great 16-35mm equvalent range, clese focussing
chromatic abberation, slow, distortion in corners at wide end

This is a great lens. Colour, sharpness and contrast are excellent. 16mm wide equivalent is essential for landscape photography and for tight spaces indoors. 35mm equivalent is excellent for enviromental portraits, a classic focal length. I quite often have this on my camera and a 50 or 85mm prime for tight stuff, my favourite walk around combination at the moment.

The bad stuff.
In high contrast areas there is quite often noticeable purple fringing. With some small adjustments to the CA sliders in bibble it goes away (about .14 R/C and .4 B/Y).
Variable and slow aperture is not great but I can absolutely live with it to get this image quality in a lens this size and weight.
Don't put people in the corners at 10mm, they look very strange, otherwise the distortion is not too bad.

If you like wide and have a crop canon, get this lens. If you don't like wide then get this lens and you will learn to love it Smile.

Canon EF-S 15-85mm f/3.5-5.6 IS USM

Review Date: Nov 20, 2010 Recommend? no | Price paid: Not Indicated | Rating: 8 

Pros: range: 15-85, IS, image quality
slow speed, zoom creep

My experience of lenses before I bought this was of the kit lenses: 18-55 IS and 55-250 IS. Compared to the 18-55 IS the 15-85 is a huge improvement in image quality and the extra range at both ends is fantastic. A 24-136 mm 35mm equivalent pretty much satisfies my general purpose needs.

Unfortunately after I had this lens for two weeks it began to suffer seriously from zoom creep between 24 and 50 mm where the lens pointed down at 24 mm falls out to 50 and then opposite at 50 mm. I decided that I wanted my new and expensive lens to be perfect within the parameters I was aware of (slow and variable aperture) and sent it back and got a replacement. Unfortunately the replacement became loose and zoom crept after a few days of usage.
Also it seemed that the replacement had worse sharpness and combined with the slowness of the lens I returned this one too and exchanged it for the safe option a 17-55 IS. I haven't looked back since. The 17-55 is fantastic, IQ is better: exactly what I wanted, no zoom creep, and fast (enough) for all the indoor shots in cold Denmark during the long winter months.

I miss the wide and the tele ends of the 15-85 but I don't miss the slowness and zoom creep. For me the 15-85 was the wrong compromise,
I love my 17-55.
