It is my newest lens, since I took advantage of the recent refurb sale.I like that one as well, however there has never been a version 2. That has been the point of my post, originals use as opposed to followups.
I recently picked up the original 70-200 f/4L as well, and I'm very, very impressed. It's now my go-to lens for the beach. Takes great shots of my wife and daughter playing in the sand or in the water, and is surprisingly light.I've done a fair amount of selling to buy when it comes to glass over the past 19 years but the one lens that has stayed in my kit is my first 'L' lens, the 70-200 f/4L. There's nothing wrong with it, it is sharp, great contrast, light and dependable. In fact if I don't need too wide, that and the pancake are a great lightweight two lens combo.
How about anyone else? What oldies but goodies do you use?
