How about a gimbaled tripod mount, like a Wimberly or the Kirk King Cobra. Done right they basically make the camera/lens combo weightless.

It does, Tim. But thanks for the link - very interesting.
The lensmount does not really provide enough support - it's located too
close to the camera mount. At least it would take a huge tripod to keep the
lens steady.

Does your lens have a tripod mount? If so, have a look at this

Very good tips.

Thanks, Tim.
I take you are talking about the M* 4/300mm prime.
IMO is does outperform the Tamron zoom. Perhaps not by miles, but it is
noticeable - even on these small (33%) images, saved for web (from 4MB to
160 KB) images.

Yes, you are right keeping thsi long lens still at 500mm 1/40 sec. is
imposible using a tripod. I beanbag would haven been better. Don't look to much at the 500mm test. All it shows is that it's contrasty and reasonably
sharp - I believe the F.6.9 and F.8 shots show this.

I don't know this Tokina AT-X 100-300mm.
I had a FA 100-300mm (powerzoom)at work. Noting to write home about!

I have tested a MF Tokina AT-X 2.8/70-200mm sometime ago. Nothing to
wrtite
home about! It may have been a "monday version", though. But I have had
two
AT-X 2.6-2.8/28-70mm Pro II. I impact damaged one and got a replacement
(still got it). It's a brilliant lens.

It seems the price level of a Tokina 100-300mm MF F.4 is somehwere between
150 and 300 USD.

A problem (for me) with Tokina is that you're never really sure if we are
talkning about the same lens/model. They seem to do small changes (often
not
for the better) during production - without changing the model name?

I paid 138 Euro for the Tamron. I believe It may just be worth it, even
though it's only a "K-lens" (green button shooting).
I don't know if I'll ever get good results, since it's so HUGE. I don't
have
a tripod heavy enough - and I'll need aditional support at the front end.
Or
I will have to rest it on a bag or similar in order to keep it from moving
;-) But the opticall quality is surprisingly high, considered it's not
even
a SP (F.5.6), which is prised at twice of what I paid. (Perhaps the 5.6
version is a Adaptall 2)

Anybody knows this, please ???



As soon as we get better weather - I'l go shoot some birds at a near by
nature reserve :-):

That's improvement Jens!

Did you put grease on the lens elements on the prime, to make the test
unfair :-)
Seriously: The prime should outperform the zoom by miles. It simply
doesn't
IMHO. This is really surprising. If it was a modern state of the art zoom
like the Sigma 100-300/4, it wouldn't have surprised me that much, but
this
is an old, slow and cheap lens.

At first I was a bit puzzled by the 500mm test. The result is better at
6,9
and 8, than it is at 11, and it improves at 16 and 22. I guess it simply
is
camera shake. Hopefully the new D2 will minimize this.
Not that _I_ can afford one when it comes. I have to wait for the prize
drop.

BTW. I have been thinking on looking for a MF Tokina AT-X 100-300/4. I
have
no idea what price I can expect, but if you are lucky you might get one at
a
affordable prize. The very few reviews online indicates it is a very good
lens. This and the AF 1,7x might be a killer combo. In good light the AF
should work.
Any thoughts on this?
