This is a great all round lens - the image quality is absolutely superb and the IS works extremely well - I have a lot of success getting good, stable pics of my kids, flowers & general day to day stuff handheld at 1/15.

Quality of construction is excellent throughout and everything feels beautifully solid - you can feel the quality!

Autofocus is very quick and usually pretty accurate but it does hunt occasionally if there isnt a great deal of contrast but then thats par for the course.

Sharpness is outstanding too throughout the range...but it isnt all a bed of roses.

I was totally underwhelmed when it first arrived - it was as soft as hell and the AF just wasnt accurate.

This was fixed by a drop into Lehmann's (Stoke on Trent if youre in the UK), who turned it round in 10 days and have completely transfomed it into what I paid £800 for.

If youre prepared to faff about like this youll get your rewards but as others have said about this lens it might take a couple of trips to the repair shop first!
