Also known as 'thank goodness you can send a used lens back'.
I have a love-hate affair with superzooms, generally loving the idea right up until I actually use one. my very first was a Vivitar 28-200 for a Pentax film camera, and even at 6X4 enprint size it was garbage. I've owned a few since, ranging in quality from 'OK at viewing distance' to 'piece of junk'. I'm not a lens snob (honest guv) have have posted images here for crit, plus printed some of the results to 30" X 20" using sigma 18-250 and 28-200 lenses. Now we're off to Israel in a couple of months, and it would be really useful to have something I can slap on the (FX) camera & just tote around for almost everything. I already have a Sigma that is usable, but with soft edges & soft all over at 200mm, and wanted something better - reading the odd review and looking at pictures on Flickr suggested the Nikon 28-200 was actually pretty decent for the type, so found a well priced used one and it arrived this morning.
Lunchtime test shots - a combination of painted fence panels from 10 feet and then walkabout shots suggest I have acquired something with an unusual distribution of flaws. The centre of the image is tolerably sharp between f8 and f16 at all focal lengths, but go more than halfway to the edge and we're into Holga territory at any aperture. While my other superzooms pretty much all flare terribly this one does not, yet it shows low contrast all over the image and the most impressive CA that I think I've ever seen. Distortion is also quite extreme and a very odd shape. I can see the softness and CA at normal screen size on a 20" monitor, so that doesn't bode well for more demanding use - it's sufficiently bad that if one stops down at 28mm looking for good depth of field, the edge performance makes it look like a larger aperture has been selected.
Sadly my quest for the holy grail of lens do-everything performance continues.
