Quite true, you will be enjoying it for quite a while already since, and Canon prices does hold on pretty well, esp Ls... and the 10-22 is a good lens too, so should be easy to sell!
I did consider a 17-40mm meanwhile..... as that will be the work horse lens for 1.6fov cam..... :think: Just that I hope they release 17-40mm MKII.....
But I think the kit will fit that space will till then, as I am considering a faster telephoto lens with USM.... 70-200mm F4L or 70-300mm USM IS..... need that faster focusing for sports (outdoor).... etc..... When shooting NDP, realised that Sigma focusing is rather slow when I was shooting apache........ lots of poor shot and OOF.....
