Canon EF-S 18-55mm f/3.5-5.6 IS

I just received this lens yesterday and put it through a couple quick tests. I was shocked, when considering the price, that the sharpness was consistent throughout, no vignetting and I had to enlarge twice the size of my PC screen to be able to pixel peep a couple teeny spots of chromatic aberration.

IQ and lightweight.

I wouldn't want to drop it on a concrete floor.

Not similar, but still a Canon zoom - the 100-400L.

Hopefully, won't need it.

Just bought it 2 days ago. This lense is a winner, excellent performance and personally I like it very much compares to my other lenses. After testing it and comparing the image with my old Canon 100mm f2.8 macro, the result shows a similar degree of sharpness, more or less bokeh and importantly, very little drop off around the edge. This surprise me a lot, if compared to the old 18-55 non IS. Some people have posted similar result in Dpreview. Even though some reviews are not recommending this lense, But for intermideate users I m recommending it. Go and enjoy the shoot.

Sharp edge to egde and across the focal length.
Fast USM
Quiet.
Fit for purpose- ie travelling etc

Plastic - But who cares if it can deliver excellent result.
