yeah bro the lizard was indeed very stressed by me stalking it. this was like 9/10feet away... I have some shots at ISO200 that the IBIS can no take it anymore as shutter speed was around 1/40-1/50 and doing MF was hard to keep still at 300MM.

these are the few shots I manage to capture with no shake as I bump up the ISO to help with the shutter speed.
This is one under rated lens I guess it was due to the 1st Tamron lens 70-300 1:2 Macro with is cheap and so-so, this was the newer and more refined version wuth Utra Sonic Drive (USD) The lens is pretty sharp bro specially when step down a bit i think the sweet spot is 7.1 or f8 I've a moon shot with this but can't post here coz used A77 to take the shot lolz.
I just realized using 4/3 sensor and using 300mm lens is not very easy must start to use monopod or tripod
