Extracto: I wasn't sure about this lens at first since it seems more plastic than the other L-series lenses I have purchased from Canon. But the images are sharp and despite the noise of the auto-focus, it appears to be good quality glass. Makes nice portraits and I am enjoying the sharp macro feature.
Resumen: I agonised between this and the 100mm f2, was it really worth so much more for IS? In the end IS, better bokeh, weather sealing and yes, the 'L' won through. The lens is good for portraits as well as macro and has delivered so far, and since the image stabilisation is so effective, I find I get away without a tripod more often than I expected.I don't necessarily think it's £300 better than the non-L lens but I didn't want to buy the cheaper lens only to feel the...
A favor: Consistent Output, Great bokeh, Quick Focus
Resumen: Fantastic lens. Excellent when used with my 550D. This lens was bought as an upgrade from my kit lens as I enjoy macro photography. Have not regretted the decision. Picture quality is so much better than the kit lens I use.
Extracto: This has turned out to be a great prime lens for portrait photography (on my full-frame camera) as well as macro photography of bugs and jewelry. I also want to give it a try with the moon rise when the weather gets better. I'm glad I got the 50mm f/1.2 and the 100mm macro rather than the 85mm or another zoom lens. The only catch with the macro lens has been getting used to the extra switch that speeds up the focus by limiting its range.
A favor: Consistent Output, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Nice Bokeh, Variety Of Uses
Extracto: I bought this lens for product and apparel work. It hasn't disappointed. The macro functionality works great and I love the ability to shorten the focal distance to speed up the autofocus. <br /><br />It feels very solidly built while still being lightweight.
A favor: Consistent Output, Durable, Easily Interchangeable, Lightweight
