Tamron 28-200mm f/3.8-5.6 XR Di Aspherical IF Macro AF User Reviews
10 out of 10 points and recommended by joe88 (37 reviews)big zoom range and extremely sharp betwee 50 and 135mmsome CA's, sometimes visible
it is comprehensible that it is very difficult for a manufacturer of lenses to correct image mistakes of such a big zoom range.reviewed January 3rd, 2015 (purchased for $80)
Nevertheless the middle range is phantastic; the extremes of tele and wide angle are still very good, with some CA's. ok. But everybody has a good photo program, nowadays.
With Phsh 4 or 8 I can eliminate the CA's quickly by a hidden switch. And if I sharpem the extremes additionally, this lens allows me big posters up to 15x20" with a good cam.
very highly recommended by me.
5 out of 10 points and not recommended by cjbowlsby (17 reviews)size, range, weight, pricewide open performance is soft, 28mm on the wide end is restricting on a 1.6x crop
It's not bad for a 7x zoom that's REALLY cheap. But then... it's REALLY cheap. It's soft especially at the long end while wide open. If you stop it down to f8 to f11, it's acceptable.reviewed December 14th, 2006 (purchased for $180)
If you really need the telephoto capability, the either of the most recent 70-300 tamrons are significantly better performers for a similar price. If you NEED the zoom range, I'd strongly suggest shelling out for the more expensive 18-200 or 28-300, both of which are far better performers, although they are nearly twice as expensive.
