The 70-200f4VR is a really great lens that I had given a test drive when it first came out. I didn’t acquire it then, had the 70-200f2.8 in my bag and its two unique features weren’t what I needed at the time. Current projects brought it back and this time, into the bag. What are the two special attributes why I wanted this version of 70-200? The real biggie is its closes down to f/32, the f/2.8 version only goes to f/22. Why is that important? In my air to air work and shooting in Shutter Priority, that f/32 really makes a difference. You might be wondering about the other end, wide open? If I need 70f/2.8, I’ll use the 24-70VR otherwise the f/4 is shallow enough DoF for me for this lens. The other biggie for me is it weighs just about nothing. It shares the same tripod collar as the 300PF which is nice but it’s filter size required the purchase of a new polarizer. Its optical performance, ease of handling and light weight, responsiveness make it a favorite of mine.
