Have had my 18-140 VR for a week now. Just wanted to share my thoughts on it, esp compared with my 18-200 vr.
Some user reviews on the net say its comparable to the 18-105 in terms of IQ .. That looks right to me, however I do not own a 18-105, though I have tested it in the shop a while back...
I got it as a possible replacement for my old 18-200.
My first impressions was .. not the best.. Its build quality seemed slightly lower than the 18-200. Weight wise it seems almost the same. Same with the size. So its not really a saving in size and weight.. just losing the 140-200 mm end of the zoom. Furthermore, there is no active VR mode just VR on and VR off. I am not sure what this means ie. is the VR on the 18-140 equivalent to both active and normal or is it just normal. It also didn't come with a lens hood which added to my bad mood .. :-)
Anyway after a few days my bad mood subsided and I took it for a walk around the streets. Usage performance wise it was similar to the 18-200 ie I didn't notice if it was faster to focus or not but I have not tested it on birds in flight. The zoom was much tighter and there is no zoom creep at all even with the lens pointed straight up or down.
Earlier today I did some IQ test shots side by side between the 2 lenses. The subject was a cheap plastic dusty chess board (about 5 feet away) back lit by the late afternoon sun. I also tested the new 18-140 with my Raynox DCR250 macro closeup adapter as it easily snaps on to the 67mm filter but not the 18-200's 72mm filter)
I have just looked at the images from my little street walk and the test shots, and I am pleasantly surprised! They are almost the same and if you don't look carefully you wont notice it. But, in almost every way the new 18-140 has an advantage. The biggest advantage would seem to me to be at the edges where the images seems nicer, probably due to the shape and rendering of the bokeh and the almost lack of CA. Overall its also a tiny bit sharper lens. It feels like its a very much sharper lens but I realized that its because at 200mm the 18-200 is really not sharp wide open and I tend to use it from 150-200 mm.
As I mentioned earlier the bokeh is really much better on the new 18-140. No where near the great cream lenses like the 85mm primes or F2.8 zooms but a lot better than the 18-200!
Will post some images and write more when I have a chance to evaluate it a bit more.. but it looks like the 18-140 is going to replace my 18-200.
