I have been testing a manual Tamron Adaptall 6.9 200-500mm (monster) lens - against a SMC FA 2.8/80-200m ED(IF) and a SMC M* 4/300mm.
The tests seem to indicate, that this is not a bad lens, that is if you can keep it still. It is rather slow. But the mechanics work very smoothly. It handles nicely - that is if you are used to "pumping iron", which I'm not :-) However, there are two major problems: It's huge and heavy as h....., I'll need a monster tripod as well ;-) It's not an Adpatall 2, so I must do manual metering, like a K- or M-lens on the *ist D. I will publish my results shorlty. Regards Jens Bladt http://www.jensbladt.dk -- No virus found in this outgoing message. Checked by AVG Free Edition.
