Yeah many Thanks to both Grotty and Darran. It's a great lens and I was sad to see it go, but I am going the prime route. This was my family walk-about lens. EXIF data shows I used it at 200mm about 85-90% of the time, and at 70 for most of the rest. Through the winter I found I wanted faster stopping action for the kids running about. Have replaced it with a very cheap but totally awesome 200mm f2.8 - can't believe it's 18 years old. Funnily enough I find myself using it at 200mm 100% of the time. I find myself moving to get in position, something I rarely bothered with when I had the zoom, and my hope is that this will make me better. I have 70 covered already with another lens, and as a treat I'm (hopefully) getting a 135mm f2, which will fill the gap. And once again Grotty has performed his matchless service of "buyer-seller alert" and I have (probably) latched onto a decent deal on one on here. I like the fact the primes are black rather than white as well. They will set me back more than I sold the 70-200 for, but those extra stops are worth it as I don't like cranking up the ISO.
Thanks again
Jonathan
