These all hand held?
Yes. Like I say, I was blessed by the light and those images are way up on what I normally experience in shutter speed as the bird was in a clearing and I am currently focusing on rainforest. TBH I currently have my tripods for sale on ebay. I have found that this lens can give me sharp images at full stretch (560mm) with as low as 1/30sec...............although I wouldn't expect a very high success rate but as an example of this lens's IS ability, the following: I am not a lover of high ISO and limit myself to 3200 in extreme circumstance in order to get the shot. This shot was at iso 3200 220mm at 1/20sec............not perfect but it recorded a first for me and yes, I know that I was lucky that the bird didn't move
And again...............a very rare bird with only 13000 known to be in existence. I exceeded my normal limits and went to 5000iso because I knew the bird's call, was following that call, and knew it would be in a dark place. As a pretty savvy member once told me when I first came to the forum me never having shot wildlife before, (I think it was Jeff/pondrader) "any shot is better than no shot" so I upped the iso beyond that which I am normally comfortable with and luckily, this lens came to my rescue...............again, not a brilliant shot but at 400mm and that iso with a shutter speed of only 1/40 sec, what other lens could produce the goods?!!!! I just love this lens!!!!!!!!
