I finally understand why this lens sells like a fiend. I went to my daughter's choir concert tonight. The last one ever. Sniff! With both the 18-70 and the 70-300.....there WERE times when the 70-300mm wasn't wide enough, but the 18-70mm wouldn't get close enough....and I'm waaaay too much of a clutz to do a lot of lens changing in the dark. Not that I'm gonna go run and buy one, but it was always a mystery before.
