It would kind of overlap with my 24-85mm...

My next lens will probably be the 20mm and then probably the 75-300mm IS (assuming it doesn't feel as cheap as some of the "L" addicts say when I try it).

Then my lens acquiscions will wait until I'm good enough to justify the expense an "L" or two. Need to build up the muscles in my arms as well !

All the lenses will have to wait until I get some work though. Thanks for the advice on the 24-85 Mark, I am very happy with it and suspect I would have missed the wide end on the 28-135.
