On which body?

Great shots, both Issac and Todders. I am particularly impressed with the depth of field you are getting at F8, it's showing good detail all over the birds plumage.
Les It does look like F8 is its sweet spot.
Great picture!
Was this taken at 600mm ? Thanks
Thanks for the reply Nick Leech. New tamron lenses means, is there any date range?
I mean should I look for a specific manufacturing date to avoid the older ones.
Just spotted this on DPReview for those interested. Tamron have updated firmware for the VC so that it detects panning motion. Of course you would have to send the lens in for the update and haven't a clue when it would be available in the UK

Birding_buddy - I have had a Tammy for a year and, although I like it, I felt compelled to try both the Sigma lenses - hoping to find they would be sharper at 600mm than the Tammy.
First I bought a Sigma Contemporary - I tried it extensively alongside my Tammy on the same camera body with the same subjects and settings. I found the Sigma was marginally less sharp than the Tammy at 600mm. So I sent the Sigma Contemporary back to the shop for a refund.
A few weeks later, I bought a Sigma Sports - encouraged by online reports suggesting it is sharper at 600mm than the Tammy (albeit at greater cost and weight!). Again tested it side-by-side against my Tammy. The Sports may have been very slightly sharper than the Contemporary, but was definitely not sharper than the Tamron. I sent the Sports back for a refund.
Then more recently, I bought a second copy of the Sigma Sports (from a different shop). I thought this was worth trying as there are reports of copy-to-copy variations with these third party lenses. Again, I tested side-by-side against my Tammy. Same result - Tammy is marginally sharper at 600mm! So I again returned the Sigma Sports for a refund.
So I am going to stick with my Tammy!
I think it is interesting that most of the people stating the Sigmas are sharper than the Tammy at 600mm have not owned them at the same time and tried them side-by-side on the same body/subject/lighting/settings. But I know of at least two websites that have performed the necessary side-by-side tests and state the Tamron is sharper at 600mm (at least in the frame centre).
That said, there are other factors to consider besides sharpness - eg AF speed, IS/OS efficiency, colour/contrast, customisability (Sigma dock), etc.
As has been said - each person must weight up the factors of importance to them and - above all, actually try the lenses out on their own camera body.
But all three lenses are superb value for money for us mere mortals who cannot afford or justify a Canon 600mm f4 MkII.
