I need to try the 400 5.6 with an extension tube. The default MFD on that is almost 12'. But how badly does the extension tube shorten your max range? Can you still focus out to 50 feet or so if need be?

It varies with the lens, but I'd guess 2 to 3-feet. 12' is actually a pretty long MFD for 400mm. What is MFD for the 100-400mm?

This nest pole was put there by PG&E (Pacific Gas & Electric) so the Osprey would stop nesting on top of the power pole, with potential both for fire, and great harm to the birds. They had to make sure it was higher, to coax the birds to the new location, overlooking the Russian River in Geyserville California

Nice shot, Kev. Beautiful cat. Sorry for the loss. Always hard.

She was the 4th one in about 18 months. That's hard.

Ed, fantastic Point Berry shot, with super light, colors and textures. That one will sell.

I didn't answer the second part of your question. With the longer lenses, like your 400mm and my 500mm, you can't focus out at fifty-feet with any useful aperture. If you're shooting a variety of subjects, you'll have to take the ET on and off.

Very nice.

Thanks, DC. Would have been better if I'd taken the time to free up my geared head and used a remote. But I just wanted to see how well the TC worked with the Siggy. Clouds moved in right after that shot, so I'd have missed it all anyway if I had goofed around with all the bells and whistles.

Happy 4th of July!!!

I actually took the teleconverter off after a while as they ended up being too close for 700mm on several shots. I never even had to get out of the car. It was a great afternoon of shooting after a dreadful morning at work!

Yeah, that's a wall hanger.

I'd consider keeping the original aspect ratio and cropping even more off the wings. You've got enough pixels to get a nice, large print.

People are amazed at what percentage of my shots are from the car, maybe 80% for birds. I call it my car-blind.
