"That makes it a 600mm f/16 maximum aperture" I should have said that makes it a 2400mm f/16 max aperture. Sorry.

Bill: One must do what one must do. Probably the best deal is either the 100-400 or the 400 f/5.6. Only problem is that the autofocus goes away on the 10D when you add a TC. Next step up is into the megabucks range. I worked and saved for two years to get the 500 so I know how you feel. The 2x TC seems to work nicely with the 70-200 but then you are at 400mm f/5.6. Extension tubes do not degrade the image. Art Morris has a 600mm shot on his newest newsletter using TWO 2X TCs stacked on a 1Ds MKII. It doesn't look too bad on the web. I would like to see the original though. He was manually focusing with that combination. That makes it a 600mm f/16 maximum aperture. Keep shooting.

Excellent shot, Fred! Very nicely composed as well as having very good details and colour!

Well, this is a good example of learning new things on Usefilm. It did not click with me that you would be using extension tubes to allow for shorter focal distance. Makes sense to me now. Thanks for taking the time to explain this... I would also assume that extension tubes would not degrade the quality as your not really stacking glass? I would really like to get a longer lens then my 70-200 2.8L, but good, fast glass + $$$.

Bill: Even in full sunlight at ISO 400-800, the background starts to look unnaturally dark when I get up in shutter speed. I may play with it a bit more if the sun is out tomorrow afternoon.
The minimum focus distance for the 500mm lens is listed as 4.5 meters which is just under 15-feet. My trusty posing branch is around 9-feet from where I shoot and the birds still don't fill the frame anyway so I stacked on three extension tubes of 12, 20, and 36mm in order to get the birds in focus. I would use the 1.4x TC II as well except that it doesn't work. No autofocus with that setup. Extension tubes work well unless you try to complicate things. I can also mount the 1.4x or 2x TC and back up but the physical layout is more complicated that way in this particular case. My 100-400 with the TC focuses down to 6-feet but I want to learn this lens before we leave for Texas next month. I'm actually giving up about 20mm true focal length using the 500 vs. the 100-400 (105-380 actual) with the TC.

Chelsea: Unfortunately, I was trying to keep the shutter speed up and, as the focusing distance was about 9 feet max, the depth of field is probably less than 2". These birds are about 4-5" long including the tail. They move so fast that I take what I can get. I would love for the entire bird to be in focus but those are rare. My earlier shot of the Black-Capped Chickadee is closer to that ideal.

Another great chickadee Fred, a bit of loss in the tail, not sure how much slower you can go with the shutter? Question, "w/68mm of extension".
Are you using an extension tube setup between the body and lens? I have heard of this for macro lens, never thought much about it for using on a long lens (other then a 1.4x or 2x converter).
Thanks!

I'm wishing it had just a tad more depth of field, the out of focus peanut butter is a bit distracting, but otherwise a nice shot, good pose caught with the beak holding a chunk of food.
