    This shot was taken with TC under bright lighting. Did some PP.

    Hi
    I prefer the shot without the TC. It seems there is some lost in contrast (which is expected as mag is higher) but if you tweak the levels and contrast, perhaps you can get the TC version to be somewhat closer to the non-TC version? Then you retain as close as the original performance while getting a x1.5 boost in zoom.
    Thanks for sharing, Ken.

    Thanks Richard for your comments, that's exactly my thoughts.

    nice shot with the bird..
    but the sharp portion of the tree branch appears to be too sharpened..
    or is it just the sharpness of the lens..?

    +1 on the oversharpening.
    Kengoh I fell your images tend to be oversharpened quite a lot.

    The shots taken with TC seems to drop a little in sharpness. so I usually will sharpen it.
    Guess I've overdone it.

    This model of Kenko TC is no more in production, as pointed out by oceanpriest, that Japanese guy left 4pcs at that time of posting, think by now left could have sold another 1-2pcs.

    instead of sharpening in PP, would it help to step down the lens by 1 or 2 stops?

    might affect DOF slightly, but for the kingfisher pix where the BG is far away, bokeh should still be ok right?

    For this shot with good lighting can try that
    But most of the time the lighting is not so good for other shots, even at F4 I already using iso 1600. If stop down will need to bump up the iso, with a TC will be worse...

    i see... plus the fact that you may lose AF when you step down also

    Yeah.
    Sometimes if I want to shoot bif (bird in flight) I may need faster shutter speed of up to 1/1000s

    i see... i have under-estimated the difficulties of birding

    have you tried panning for BIF shots?
