I rented the 100-400 over 4th of July weekend and used it for water skiing pictures from along the water. I really enjoyed the zoom capability and found the sharpness to be good, although I think the rental was below what a well maintained lens could deliver.
Here's the thing, the 100-400 is pretty pricey, so I was wondering if anyone could throw out some suggestions for substitute lens that have the same focal length and relatively close IQ. My budget isn't super low or anything but something around 800 would be nice.
So, should I just save up more for the 100-400 or are there other comparable options?
Thanks!
Mike
