Well, I just picked up mine from the post office and love the solid feel of it. Drove all the way from my country house to come and get it
I went straight to the nature park near my place and started to put it thru it's paces, and this is a pleasant lens to use! It's got a good tight feel to it.
I snapped away for a little while, but was pretty wobbly without my tripod or monopod. Those are a few quick snapshots. Those are all wide open at 300mm. No PP except for cropping and resizing when needed.
As you can see in the last pic, at 300mm wide open, there is some PF in the high contrast areas. (I have to admit I am pushing it as it's a pic taken in a shaded area and the PF appears in the blown out areas where there is a sunray coming thru)
I like this lens... I really like it
Pat
