    I take 3 mile health walk most days when I am home and noticed lots of fledged Ospreys, some of them down low so I decided to head down to the lake with my gear. This young bird was sitting atop a telephone pole--bad, but he allowed me to get out of my dar and work off the tripod--good.

    I created this image with the Canon 800mm f/5.6 L IS lens, the 2X II TC, and the EOS-1D MIII. ISO 500. Evaluative metering +1 2/3 stops set manually.

    With the bird constantly moving its head, focusing manually and creating consistetly sharp images was pretty much impossible.

    I did some extensive bill clean-up using a series of QMs. I love the raised crest. Only one thing bugs me about this image; can you come up with it?

    I like the wind-blown plumage, exposure control and the details are great considering that you used a 2x TC. Did you take the crop factor into consideration?

    There are a few dark spots in the BG and on the left side is some clone leftover. As for being 'bugged', the head angle?

    Wow, that is some sharpness at all that lens mm.
    Very pleasing image...

    About the thing that bothers you about it,
    I will take a risk and say: eye contact with the camera?

    Cheers, Ilija

    Hey Axel-eyes,

    re:

    Thanks and yikes, I screwed up the math. Correct should be 800 X 2 X1.3 = 2080 (not 800 X 200 X 1.4). Sorry for the brain typo.

    There are a few dark spots in the BG

    Yikes! There were about 12 fairly large dust spots partly a result of the small aperture and pertyl a result of neglecting to clean the sensor, relying too, too much on the Integrated Cleaning system. Thanks. I re-did the master file.

    and on the left side is some clone leftover.

    I do not see that at alll there was no cloning on the left. There was a bit long o-o-f dust spot or something that I removed. That might have been it. Let me know if you see it in the repost.

    As for being 'bugged', the head angle?

    You are too smart. I wish only that the bird had turned its head one degree more towards me.

    I'm always glad to help. The one larger spot is gone, I guess that is the one you mentioned. There still are two more spots, one above the head, the other one in the upper left.

    Great image, Arthur. Having owned the 800mm f/5.6 IS lens and 1D mk3 body, I know how difficult it is to focus manually with a 2x TC since the viewfinder is pretty dark (wide open at f/11), especially when the bird is constantly moving its head. I find that it's easier to focus manually using Live View zoomed in 5x. The in-camera IS helps facilitate focusing by stabilizing the image in the viewfinder or LCD display.

    I give up. I went through the TIFF slowly at 100%. You spot them from an 800wide JPEG. Yikes!

    Hey Ed, That sounds like an intriguing idea, but how do you stablize the lens when using live view? I like to keep my forehead/face pressed against the camera back as part of my sharpness technique....

    Handsome bird perfectly composed and great job with the 2x!

    What was your SS and aperture?
    Wondering why you stuck with ISO 500 when I'm assuming you could use all
    the SS you could get with that focal length?

    I use a remote cable release and half press the shutter release button to activate the Image Stabilizer. Unfortunately, you cannot keep your forehead pressed against the camera using Live View. But it sure is easier to focus because the LCD display is brighter than the viewfinder at f/11

    Oops, I am losing it: 1/200 sec. at f/14 set manually. The problem as I saw it Mike was one of accurate focus, not one of shutter speed. I think that I could get them sharp with that set-up at 1/60 in part because of good technique but more importantly because of the amazing IS system in the 800....

    I have never been able to make as sharp images with a cable release as when I have my head against the camera back. And again, it was not so much focusing accurately--the viewfinder was bright enough--the big problem was that the bird was moving its head.... With a still bird the Live View might work well for me.

    I would have thought a good image before this site but yes the head angle isn't ideal. I think you run an action for web posting but there seems to be a halo around the bird. I'm impressed with the sharpness though.

    That's more magnification that I could deal with!

    The four stops of IS help but is not all I am sure. Very powerful portrait, I don't care too much about the HA as I do with the neck that looks a bit dirty or something like that.

    Yeah, those dirty looking yellow feathers but me too. Probably got some fish guts on them.
