Well it was a small bird about 42 feet away. What the heck - I put a 2x converter on my 800mm lens and gave it a try. There is a practical limit to huge focal lengths - DOF. I think I had about 1/10 of an inch to play with - manual focus. Bird was also in shadows, so I didn't have a lot of shutter speed available. Not a very good picture, but thought I'd share because the setup was interesting.

D7000, ISO 1400, f13, 1/30, Sigma 800mm and 2X (1600mm), remote release, MUP, Wimberley II, Gitzo 5540

Pity there wasn't a bit of colour in the tree trunks Chris. Otherwise i'd say you did a pretty reasonable job with your 'Howitzer'....Scotty.

Chris,

If you were using a D700, Sigma 800mm and 2X converter it would be equivalent to a focal length of 1600mm. However, since you were using a D7000, which is a DX format, you have to consider the multiplier of an additional 1.5x which gives you an equivalent focal length of 2400mm. Now that is a Howitzer!! Considering the DOF you get with that focal length and the lack of control for lighting your subject, I think you did a good job of capturing this Junco. I know when I see them it tells me that snow could be close. Thanks for sharing.

Well, the bird is reasonably well focused, so I would say it worked within the limitations of such an interesting setup. You got it!

Nice shot Chris. It may not be tack sharp, but a good shot nonetheless. How do you like that 800mm lens? That's alot of power considering the teleconverter and the crop factor. The slightest movement can alter the clarity of the shot. I can see a difference when I have my set-up locked down as opposed to when I don't. With wildlife, of course, locking everything down is not always an option.

Thanks for sharing,

Chris:

The only thing wrong with this photo is that you need to do some additional post processing on it.

Here is a quickie using CNX.

The adjustments were:
Levels and Curves - Left slider to value of 5 and right slider to value of 170.
Unsharp Mask Sharpening only on the bird - Intensity 40, Radius 5, Threshold 4.
I then went back and added USM to the eye only - 20,5,4.
Added Noise Reduction to everything except the bird - Intensity 10, Sharpness 5.

Give it a try with whatever PP software you use. I'll bet you will be suprised at how good you can make it look.

Now that did some really good PP. We all learned or were reminded about those possibilities.

Thanks Vaughn,

I love the 800mm. I almost never use a converter with it and when I do, it is generally just playing around as I was with this shot. In the past when I've tried it, I've locked it down with a ballhead and a Bogen long lens support or a second tripod.

I always do just as well or better without a converter - especially with the D7000. The vast majority of the bird shots in my gallery were taken with the 800.
