The Minolta 100-200 F4.5 is a cheap alternative for a zoom lens if you have the LA-EA2 off course. I was about 10 ft from the stage. The AF of the LA-EA2 (what's it call..aaa..ya..Phase Detection) is fast and accurate. Took the opportunity to used it at these young talented kids concert here in Kuching recently. Well its not a really comprehensive review, but my mark on the Minolta is 3/5 and the flash also 3/5, mind you that the max sync speed of the flash is 1/160s ( professional wise - not good, but who am I to say, I am no pro).
