I know it depends on what kind of photography I do... but I am open to and like to explore new areas. I just sold my 100-400L since it did not give me a whole lot more reach/ sharp images as can my 70-200mk.ii with a 2x mk.iii, I would like some reach but the good lenses are very pricey. I like Macro/General people pics/citi scapes/landscapes etc.
I already have the 17-40, 70-200, 50 1.8 mk.ii, 180L. I got the 17-40 after selling a good copy 24-105L, while I like the extra width, I feel the corners are so mushy and distortion very noticable at the corners that I do not use that extra width... should I wait for the 24-70mk.ii or get the 16-35mk.ii ? I love the 70-200. I use it the most.
My budget is about $3500. I am a hobbyist, and would probably re-sell the lenses after I get bored with them since I do not make money off the hobby...
Are there new avenues / lenses I should explore? What would you guys do?
