I have an 80-200 2.8... Its big and its heavy... It has one use only. I use when covering the horsracing.
For all other work I use one of my fave zoom.... The 70-210 4 - 5.6 D.
Its an old, but like new lens. Fast focus, good optical quality and amazing build quality etc.
I didnt buy it for any of those things though. Although it helped lol.
I bought more for its fantastic buttery smooth Bokeh ! I love it. It might not produce the most detailed prints
as a few of these new lenses, but I would not swap it for any of them.
it just produces beautiful pics time after time. Best of all, you can pic them up for around £130.
