Canon 17-40 f4L vs. 17-55 is usm

Thank you for this eyeopener. It still makes my decision a lot harder again :P I hoped that the 17-40 wasn't that sharp so I could finally rest my mind ang go for the 17-55, but your comment makes me doubt again. Later this week I will try both lenses at my local store and I was nearly there to buy a 17-55. You got a 100mm macro that I have as well so you know what I mean when I say sharp. Thus if you think the 17-40 is sharp as well, I really don't doubt it. Also no I'm not planning to buy a FF camera, I like the 1.6 crop. Man this is a hard decision Still not convinced..

OK, maybe this will help: The 50D isn't fully weather sealed, so the sealing on the 17-40L isn't a decider. Unless you are pretty rough with your lenses, you won't need the rugged L build. With the 17-55 the extra 15mm reach at the long end and theextra stop(f2.8 v f4) will probably be very useful to you. If you're not planning a FF upgrade and you treat your lenses with care then its the 17-55.


Hmmmm.... the more I think about this, the more I'm considering trading in my 17-40L for a 17-55 []

I don't know what you mean by rough :P I treat my lenses with absolute care, but as I stated, I like to take pictures at different sport events. Inclusive motocross etc... Take a look at my picture what shows about the roughest my lens had to face.

This doesn't mean that it's always such a mess where I take pictures, but... it is possible :P


So far I'm really convinced by the 17-55's extra 15mm, 2.8 aperture and IS, for only a small amount more. I just want to see and test both lenses and I made an appointment at my local store for tomorrow so.... I'm going to see them both and hopefully I get the chance to test them both a little. I must say the 17-55 is still in favor, but I might change my mind tomorrow. I'll be back later


I will definitely tell you all which lens I buy at the end of all this and why I bought it. Might be a fun thing for you as well (I think)


Until that time don't hesitate to comment on anything. Every tiny detail and idea I can use to make my decision.
