compared to:Tamron 18-200 early model, such an improvement
Tamron 17-50
Sony 16-105
price paid:£180 new, a steal!
positive:Sharp, fast focus, light weight,
negative:Can`t think of any at the moment, oh hunts a bit in darker conditions - backs of rooms etc,
comment:Bought as a walkaround general purpose lens, (daughter nicked the Tamron) without too many expectations, but found it a lot more useful, and far better than expected especially at the price a good balanced fit on the A68, so much so that it spends more time on there than the Tam 17-50!

comment:Despite no reviews on dyxum I decided to buy this lens based on reviews for the other mount types and I can say I am happy with it.
I used to have the older (first) screw drive version of the lens which served me well for some time, but I wanted a video capable lens for outdoor events - and the screw drive was just too noisy.
The new version is better in:
1. Sharpness - it is actually pretty sharp wide open for a superzoom (as far as I can see from web images, it is sharper than the Tamron 16-300).
2. Close up capability - better magnification, better sharpness.
3. HSM quiet enough although clicks can be heard when changing direction.
4. AF seems to be more accurate than the old version.
It is worse than the original:
1. AF speed - I was surprised by this, but the screw drive on the old version was noticeable faster than the HSM in this new version. It's still usable, but especially at longer focal lengths it moves in steps around the final position which may result in missed shots. Having said that, it may be the price for better focus accuracy - it's spot on all the time, while I used to have quite a few misfocused outliers with the old version.
2. Vignetting at 200mm wide open. It's pretty strong but easily correctable in post.
Things that are about the same as the old version:
1. CA - it's there, but not very visible at normal sizes and easily correctable in post.
2. Distortion - yeah, it's a superzoom.
3. Build - plastic, but seems sturdy enough with no zoom creep so far. It's very compact - good for travel.

It should also be noted that it's a Global vision line lens, so the USB dock can be used to microalign AF back/frontfocus, although it was not needed for my copy. This can be useful as most Sony bodies don't have AF microadjust - in particular the entry level bodies, which this lens is primarily targeted for.

So I love this lens for what it is - a versatile compact travel lens with image quality that is above its current price level. Amazing value.
