Been reading the lens posts that have been on these forums for some time and gleaning good insight. Ive now saved up almost $1500 towards my lens collection. (I will then start over for the next purchase or add to it for the first purchase) At this time I have a 18-135mm EF-S for my Rebel T2i. While it does the job for me, when I compared the pics from this lens to the pics I took with a 70-200mm L IS USM... doh, I like the sharpness and clarity the L lens gave.
In looking at my pictures, I tend to like landscapes (my favorite), travel and people/wildlife requiring longer zooms and have been checking the pics I like and Ive taken them in focal ranges from 18mm to 200+ (with the rented 70-200 & 2x TC in Alaska). Looking ahead, Im figuring in hopefully a year or two i'd upgrade the body to possibly a 7D, but if I get real good, I would consider a full frame for landscapes.
So... Ive kinda narrowed down my prospective lens collection (of course it can change later) to 24-105mm f/4 L IS USM, a 17-55mm f/2.8 IS USM (If I stay with a crop camera). Depending on what I end up with, Ill decide on a wide angle lens later if I want one. So, right now, Im kinda in a pickle determining which longer lens I should go for... the 70-200mm f/4 L IS USM and 1.4x extender or the 100-400 f/4.5-5.6 L IS USM.
Considering I currently have a 18-135 right now that I can live with... which would make the most sense for the next lens upgrade purchase, being done one at a time?
Thanks for your input and making ANOTHER lens recommendation!
