    I apolize for having misspoken. I am now not sure of what I was thinking when I posted that. The raw files are 22MB and the "best" jpeg is 5.6MB (frame size is 5184 x 3456 pixels). Native resolution in the camera is 240dpi for raw files and 72dpi for jpeg.

    A typical web representation of ANY photo shouldn't run much over 100-200 K. I run 1440x900 widescreen monitors here, and that's only about 1.3 megapixels if you bitmap every single pixel. 1080P Hi-Def video doesn't even hit 2 megapixels.

    What are you doing that generates a 16MB jpeg file? I can guarantee that your camera isn't generating this. The SX-30 and D7000 here don't generate jpegs anywhere near this size, and I have to reduce them by a LOT to make them usable for web stuff.

    Stats for the tripod (bolt and washer) shot I posted:

    Taken with the SX-30:

    Original was 4320x3240 (14 MP). Jpeg was 2.69 megabytes.

    Cropped it and reduced the crop to 600x384. Added a bit of sharpening. Result was 70.9 KB.

    Just wondering what you're doing to produce a 16MB jpeg...

    No Tokina lenses are listed among the bazillion lenses in the Adobe Camera Raw 6.3 lens distortion and chromatic aberration drop-down. Curious. Sigmas and Tamrons are represented extensively, along with all the camera mfrs' offerings, as one might expect. No mention of Tokina at all.

    I should be fair to the lens and state that its worst aspects are at the extremes of its exposure range. At about f5.6 things sharpen up and they are pretty good at f8 and f11, though no one is going to be fooled into thinking it is a Canon L series lens. ;)

    Ah, that makes perfect sense. Great shots, too!
