I was messing around with stacked TCs yesterday. I put together the Nikon 1.7x and a Tamron 1.4x on my D800 using an AFS Nikkor 300mm f4.0. This made a minimum aperture (according to the camera) of f6.7 - However, I think it is actually f7.1 - regardless, the D800 focused accurately, and relatively quickly in flat light. I didn't expect that! A 700mm lens that I could hand hold.... Here is the full frame.

Cool trick! How is the focusing speed?

Not bad...maybe not up to BIF, but for perched birds, and other long reach situations I think it would work. I really thought the AF would just refuse to work - it was a pleasant surprise.

Hey Jim,

What a cool looking shot. The AF on the D800 is nothing short of amazing. I have had it at over f8 and it will still autofocus. Stacking the converters is fun, the best part here for you is the sharpness of the image as often that's where stacking lenses like that can go bad. But your shot looks sweet!

Here is a Blue Jay...same combo, but a bit of a crop. I think this is softer due to camera shake, but still...pretty good.
