Nikon 50mm f\1.8D and Tamron 18-270mm on D800

HA! I found out for the Nikon lens:

Handy! Yes, my 50mm 1.8D is FX.
Not to figure out the Tamron!

The Tamron is definitely a DX-only lens. Whether Tamron's reverse-engineered in-lens chip/software will correctly tell the D800 to behave as a DX body is another matter. But you can always throw the camera into that mode on your own, regardless.

Found the info on the Tamron. :( It's going to force DX mode.

Thanks, Matt.
I'll probably keep my D7000 anyhow. So the Tamron would probably be permanently glued to that body.

On all Nikon FX bodies, the auto DX crop feature (when you mount a DX lens) is optional. You can always force the FX body to capture the entire frame or the DX crop frame, regardless of which lens you mount on it.

Thanks, Shun.
My real motivation to the question was whether or not I would be needing to buy lenses. Looks like the answer is yes. I'd have my D7000 with the 18-270 but for the D800 I'd probably want to get a lens or two.
105 macro would be nice.
And a more versatile zoom would be good as well.
Time to really assess the cost of upgrading. It would be splurging no matter how I look at it. Not getting paid for taking pictures (yet).

Regardless, Jared, that entry-level 18-270 zoom - even if it could cover the FX-format sensor, which it can't - simply doesn't have the optical recipe or quality to take advantage of the D800's super high resolution. It's truly not worth fussing about such a change unless you're ready to buy top-flight lenses.

Matt makes a good point. You have to consider not only the cost of the D800 but also the cost of new lenses. And to take advantage of the D800, you need top-flight lenses. Your D7000 is an excellent camera. Maybe you should consider building your system around it.

No reason you couldn’t put the Nikon 50mm f\1.8D on the D800.
