So, the used Panasonic 70-200 f4 that I found at Fforbes in Scotland arrived today. And it's a keeper !!
I was beginning to think there was something wrong with my technique or my sanity that I couldn't find a tele that worked for me. But this 70-200 f4 just delivers very sharp images edge to edge right out of the box. It's even acceptable (just) for landscape shots wide open. At f8 it's really very crisp.
For those who don't know, here's the journey:
70-200 f4 copy 1: I bought this used from MPB but the front element had a scratch on it so it went back. I decided to go for the 70-300 on price grounds and after reading reviews.
70-300 copy 1: Decentred with a soft left edge. Returned.
70-300 copy 2: Very sharp and I kept it for a year, but I would sometimes get unusably-blurred landscape shots that I eventually diagnosed as hit-and-miss focus in some circumstances.
70-200 f4 copy 2: I got a copy from Panasonic on their loan programme, but it was badly decentred with a very soft right edge.
Sigma 100-400: I liked the IQ from this lens, but it was just a bit too big and heavy (although on reflection, it's actually not much bigger than the 70-200 f4).
28-200: I bought a used copy from MPB. At 200mm it was just plain awful until stopped down to f11. Probably a lemon.
70-200 f4 copy 3: It works! I'm happy!
I'll post some shots up in due course.
