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.
