    The older version (the size of the 40-150mm f2.8) with newer coatings, not the newer stabilized lens (the same size as Olympus 35-100mm f2.0). Cheap at twice the price :) 

    Wide open at 150mm.
    P1050961-1. Do people actually take pictures of birds wide open?

    Wide open at 80mmish.
    Just imagine that this is a person instead of a tree: one eye will be in focus, the other eye, both ears, and nose are going to be out of focus.

    Wide open at 50mm
    P1050892-1. Stick torture test, there's pretty heavy longitudinal CA seen as green fringing in the out of focus areas.

    90mm ish stopped down to f/5.6
    The limit to sharpness is going to be a combination of mirage due to it being a 40c day and me on my toes holding the camera up high in the air to get it above a tree (the key point to me was that I could actually do so, it's nice and small/light).

    I think I'll keep it, it's not perfect optically however it's a pretty reasonable compromise given the price paid (USD$230).

    Testing how slow I can go at 150mm resting it on a monopod without shake for web use (1/10th of a second, both had small amounts of blur but acceptable for web size). Anything slower wasn't viable, faster was almost universally boring due to lack of water movement.

    Doggy tax.

    F/2.8 @ 58mm, a drippy nosed dog is happy, two drips means heaven.

    F/2.0 @ 42mm, really needed to stop down a little but didn't... not being lazy and getting a larger reflector probably would have helped more (more reflected fill light would lower the contrast between shadow and direct sunlight...).
