I have read a dozen reviews about the Tamron 150-600. Most of them are made with Nikon and Canon camera's. Some of them say
that it has slower focus depending on which camera you use. How does it compare to Sony. I have the A700, A900 and A580.
I won't be slower than the screw focus I hope, and maybe faster than the SSM on my 70-300G. So if that is the case, than for me
it's all ok.
Some say, it's not quite sharp at 600, but al lot sharper than what Sigma had with their * - 500 lenses. So for me that's a possitive point.
Offcourse, you can't start looking at lenses that cost 10 times that much to say that sharpness and contrast are worse.
If you have a VW Golf, it won't be the same quality as a BMW 645 for example, and that doesn't even cost's 10 times that much.
I don't have the privelige of buying lenses of 2000 euro or more. And in my opinion, the Tamron is the only choice available if
I would like to take descent pictures at 600mm.
What do you think?
ps, I will propably buy one this week
ps sorry if the english isn't completely correct, it's early morning
