ownership:	I own this lens
compared to:	Sony 24-240mm Sony 24-105mm f4
price paid:	£899 (new)
positive:	Sharp lens especially on a 24mp body. Fast aperture through a good range of the zoom focal lengths Good AF, with flare and distortion reasonably well controlled (in fact for this kind of a lens its very good!) Its compromise is very obvious, nothing hidden and horrendous like other superzooms (look in negatives below)
negative:	Only 28mm start but I suppose that keeps the lens compact and optical formula simpler to make this lens sharp at the range I does provide. Rendering especially sunstars and bokeh not the best. No OSS
comment:	This is a very viable alternative to the 24-105mm f4 G which is actually you a rather sharp lens through the zoom range. What you lose in reach on the wide end you make up for in reach at the long end and also a stop more light at 28mm. The results from this lens does give more resolution than just cropping results out of 24-105mm, so that is a pretty good result overall. Sony 24-105mm does render more nicely and sunstars are very nice in comparison. the Sony 24-240mm isn't really a serious contender when it comes to IQ.
