An important fact also is where you anticipate using it. Shooting from a
parked car/nearby or in a sports arena is where the bulk/weight isn't as
much an issue as using it in the bush where you might be hauling it around
to follow the wildlife - like I did on numerous occasions with my 600mm kit
in Denali.

Thats good news but you should be prepared for the extra bulk and weight
of it over say a 300 f4.5FA. I haven't shot with the Tamron but it is
defimitely not as hand-holdable as the 4.5.
I have the Tamron 300 ƒ2.8 in AF form, and it is needing a tripod with a
sandbag hanging, and a 5 x 7 bag full of lead shot draped over the top of
the camera to guarantee sharpness, especially if you've got a 1.4x or 2.0 x
tele-converter hung.
Nonetheless, I have shot with it handheld on many occasions with from very
fine to lousy imaging. Wide open is gives you a lot of CA. ƒ4.5 ~ 8.0 it is
at it's best. If you are young and strong and steady, you'll get many more
keepers than I can come up with. If you could look through my finder when
I'm trying to shoot a static object handheld. Even the anti-shake can't
overcome the movements that happen no matter how hard I relax and breath out
half way before tripping the shutter.
My 2 cents.

There is no off position to the genius switch.
Genius can, however, be observed as insanity.
