in spring I bought 60D with 15-85 and I was pretty happy about it. Based on reviews and shots it should have been very good lens and it really is. When my 100L was delivered this september I instantly realized I like images from my 100L much more.
Basically now the situation is, that my 15-85 is stuck in bag until I really want to take wide shots like landscapes or there is no working distance. Also there are much less keepers from 15-85 then from 100L.
Should I consider selling 15-85 and upgrading to 24-70mkII or 24-105? Is it worth for 60D? I like to shot wide open so f/2.8 would be advantage for me, but €2k+ pricetag is something what make you think. Standard zoom is very useful lens to have for general shooting. In the future I would like to move to FF so please consider this too. Somewhere back in my mind there is also idea of buying 50L (based on posts here) and maybe later add some wide and fast prime.
So guys, what are your thoughts?
