Impressive lense.

Glad your happy with it.  Excellent build.  Terrific wide angle zoom on full frame bodies.

But as "an every day walk about" it is suboptimal on 650D and other APS-C sized bodies.  For less money the EF-S 15-85 f/3.5-5.6 IS USM is much better in every respect other than ruggedness.

IMHO, YMMV

Thank you so much for the tips. The lense that you mentioned actually came with the 650D and took beautiful pictures, lite and complimented the camera perfectly. After about 2000 frames I decided to upgrade to an EF-S 18-200mm f/3.5-5.6 IS and had used it for another 2000 frames, but reallized that it was too slow at certain focal distance and not as good as the 15-85 lense, but loved the zoom though. So, I went for another upgrade and had my eye on the EF-S 17-55mm f/2.8 IS USM but it is on a pricey side for what it is comparing to the " L " lense that I ended up with. So, there is a method to my madness I must say, but eventually I will have to uprade my EOS to " optimize " the ' L' lense, any sugestion?

IMHO the only advantage EF 17-40mm f/4 L has over EF-S 17-55mm f/2.8 on an APS-C body is lower price and better weather sealing. On a FF it is a mediocre wide zoom that gives low IQ in the corners. Your 650D + EF 17-40mm f/4 L is a good combination but even EF-S 15-85 f/3.5-5.6 IS USM will definitely give you better IQ and flexibility. In this case 15mm is substantially 'wider' than 17mm. As for EF-S 17-55mm f/2.8 IQ... This lens is one of the reasons I still keep Canon APS-C bodies. 

If I were you I would try to test EF-S 17-55mm f/2.8 on your 650D body before upgrading this body 'to be good enough for EF 17-40mm f/4 L'. Don't be hypnotized by the beautiful red ring! Not all 'red ring lenses' are created equal!

My only suggestion would be to please spell 'lens' correctly.
