Bought this a year ago when I went to get the Sigma 50-500, which was out of stock for Sony mount, so I bought this as it also got good comments in dpreview.com.
Using both Sony A100 and SLT A55V with this lens, brings great shots hand-held for medium range. Continuous focus of the A55 tracks an quickly maintains focus on flying birds.
I have also used the 2x teleconverter with tripod for some quite good results (especially one of the moon iso100/f11/ S1/100). Manual only focusing, but the smooth focus ring action when using the Alpha55 x7 and x14 focus zoom feature, means a crisp focus is achievable.
Medium distance telemacro effect using extension tubes with this lens in good light has also delivered good shots of Butterflies, wasps etc..
