From my siggy you can see I have pretty good selection of lenses for a crop sensor camera. Although I plan to sell lots of my crop lens inventory soon.
I plan to purchase a 5d Mark iii and start slowing building up my collection of lenses designed for full frame cameras. Not sure precisely where to start. Both my Canon 100-400L and Sigma 70-200 f/2.8 perform just fine on the 5D Mark III. Likely won't be starting there.
A few lenses I am considering are:
16-35MM ii f2.8L
24-70mm f/2.8 New Tamron lens
I plan to shooting a lot of indoor sports and cheerleading competitions in the fall. I think I will need something that pretty closely resembles on my 17-55mm f/2.8 lens but for full frame.
Any suggestion? I am dropping some serious coin on the camera body and lens purchase so I will have to live with my choice of lens for quite a while.
