ownership:I own this lens
compared to:Sony AF 70-300 F4.5-5.6 G
price paid:
Does not extend during zoom or focusing
Build quality
negative:Weight, but this is unavoidable given the all metal construction and constant F/4 aperture
comment:I bought this lens on Ebay just as it went out of production and it has become a favourite lens. it is a big and heavy lens, and it is not exactly unobtrusive, so I take it along when I know I am going use for a special purpose. It has not made me want to sell my 70-300mm G as this compact, light weight lens in comparison and ideal as a travel lens.
i have used it with the Sigma 1.4x tele extender with good results, but IQ is somewhat reduced at 420mm F/5.6.
