Re: Tamron AF SP 300/2.8 LD (IF) + Tamron-F 2X TC.

I have been toying with the idea of getting a Tamron Adaptall 300mm F2.8 for use on days when the light is a bit lower.  They do appear from time to time on ebay at anything between £350 - £500 used. I even saw two unused / unsold new units from a seller in Taiwan for about £1400.. but wasn't looking to spend that much!

As I probably wouldn't be using in areas that would give very high contrast (sky background etc) then the PF / CA might not be such an issue.  I'd also be looking to use the Pentax 1.7x AFA with it quite a lot to give AF capability.

So, would be grateful for some opinions on this lens (the 60B model) and is it worth a punt?
