Shot RAW, processed equally in ACR 4.1 and PSE 5.0. VR, AF amd AE all active in both shots. 100% crops.

The first shot is very sharp, but the second is a bit soft and has an incredible amount of CA. Are these 100% crops?

Yes, they are 100% crops. I hadn't noticed the purple fringing until you pointed it out. At normal viewing magnifications the results aren't bad. I'm glad this isn't a $1200 lens!

Still a very sharp lens if you don't use the kenko, so a good buy!

Thats not too great with the Kenco on. somehow it convinced me not to get the teleconverters. Sorry to say it looks a bit disappointing. Was this handheld with VR or on a tripod? Maybe Tripod will look better? keep us updated. The lens by itself is sharp.

What would be interesting, Bob, is to crop the image without the converter to match the magnification of the image with the converter and compare those.

I've done this myself, with the same combination, and still am not really sure which is better.

To me the reason for the tc is to get closer than you could otherwise. With my D80, the ablity to crop and enlarge the image is maybe better than the quality achieved with the Kenko. (like I said, I'm still not sure which is the better image).

I think I've lost my test pics, so if you could post a comparable magnification image, it would be good to see those results.

Thanks, :-)

Both photos were hand held with the VR on.

The Kenko was a $350 solution to get a bit more telephoto action without getting into $1000-$1200 lenses so you get what you pay for! 100% crops were posted so it is pushing the envelope. At normal magnifications it doesn't look as bad.

I'll have to test on the tripod and see if it makes a difference.
