Tamron 150-600 Tests

After reviewing yesterday's photos I wanted to play with various focal lengths & apertures.

So back to Camp Cronin at Point Judith for some tests :)





1)
So I think I need another set of tests at closer distance -- I suspect the 600mm length will exceed at stuff like close-ups of wildlife more than pulling in distant shots.

2)
I also need a heavier tripod to handle this lens. I left the "VC" image stabilization on because the camera was shaking quite a bit and I had to stabilize with my hand. A more secure tripod and remote trigger may have let me turn off the stabilization (since the camera *shouldn't* be shaking on a tripod at all) and gotten a bit sharper.

Checking the math: Camera 1.8#, Lens 4.65# = 6.45#

Label on my tripod: "3.3#" ...yep I'm a bit over specs :D,BR/>
Here are three shots at 600, 400, and 300 -- initially I was thinking the 300mm or 400mm shot cropped would be clearer than the 600mm shot, now I'm not sure. I almost want to kidnap Becky + Whats His Name to have them be models to work on this shot again :D

The end of the breakwater is about 650 meters from where I had the camera setup.
