Thanks

Yeah that's what's holding be back. Love the optics but AF does seem to have bad reviews.
Lack of VR I could potentially live with if the optics are as good as it looks...

I think the sigma converters will be best as they are matched to give the best performance. Avoid cheap makes they will be a disappointment.
The AF on the Tamron is woefully slow, the OP thinks its fast because he hasn't used anything to compare it with, when he tries a Nikon or even a Sigma he will realise the Tamron is a dog as far as AF speed ans accuracy is concerned.
Tonto said:For those who think the Tamron is a lemon, check the Tube for " 70-200mm f2.8 shootout "
Ignoring the lack of VC ( big difference if VC / OS / VR is important ) and checking the IQ at various settings and distances, the Tamron scored really well, and although a hairs width away from the Nikon at twice the price, the result is amazing.
The vid on the Tube is in 4 parts, ( That Nikon Guy Matt Grainger ) and the shootout is the Tamron, Nikon and Sigma. Both the Nikon and Sigma are stabilised.
Tonto said:It aint that much slower though Phil... check the vids. The Tam is a pretty amazing lens if you can live without VC.

not only is the af woefully slow and noisy the dog engagement and disengagement from af to mf and vice versa is apparently noisier than changing gear without a clutch in your car
You Clearly Haven't used one....

Flash In The Pan said:Have you used any other similar lenses (the Nikons, for example) to draw a comparison?
Joeturner11 said:Nope it takes about half a Second to lock on!

Phil Young said:Well I wouldn't compare it to afs but that would be good enough for me. I can't (don't want to) afford the Nikon so that would be the compromise...doesn't seem like a huge one...

Gary Coyle said:Like ive said, the OP hasnt used a Sigma or Nikon, if he had he would also be rubbishing the Tamron because it is rubbish in comparisson AF wise.
