My brand new TAMRON AF70-200mm F/2.8 Di LD (IF) Macro

The lens arrived 2 weeks ago but couldn't make much use of it for most of the time.
Preliminary findings:
Slight misfocusing tendency obvious at f2.8-4 when focusing to far away objects. I think that this is because of the very-very small step necessary to focus from 10m to infinity (the motor just "ticks" for that)
Very good macro
Excellent resolution and minimal CA.
I'll post photos as I take them.
For now there is a quick and dirty macro photograph with a 100% crop.
Hand held, f11, 1/125sec, ISO 400, K10
Taken in raw, no post processing, just export to jpeg with Lightroom 1.4

On the weekend I intend to confirm the misfocusing problem with controlled conditions and the camera on tripod.
Maybe I'll do some nature macro work also.

I'm also very happy with mine.

Very sharp.

Seems to work very well with tamron 1.4x teleconverter.
(If you don't mind I can later post 1 or 2 images here)

I'm thinking on getting a 2x converter to see how it will work and the effect on IQ.

Nice pic, post some more! Had mine for 3.5 weeks while visiting florida. I find it a bit quirky, but am undecided if its me or the lens. Heres a few:

Post a couple with the tc if you have them. I'm curious as to how well it works.
