Nikon lens/bodies

If i was to put a lens WITH motor on a body that had an internal motor what would happen?

double-speed AF?

Actually, Google is your friend...

From the Nikon US site

"Nikon makes two different types of D-SLR camera bodies—those that have a built-in focus motor, and those that don't. The cameras that don't have a focus motor built-in need to use a lens that has a focus motor built-in to it. The abbreviation for lenses that incorporate a built-in focus motor is AF-S. NIKKOR lenses that do not have a focus motor incorporated into it are simply called AF lenses.

The D-SLR camera bodies that do feature a focus motor built-in are: D70, D70s, D80, D90, D100, D200, D300, D300s, D600, D700, D800/D800E, D7000, D7100 D1-series, D2-series, D3-series and D4 models. These D-SLRs can utilize both AF and AF-S lenses. Or, in other words, because AF-S NIKKORs have the focus motor built into the lens, they can be used on any current Nikon camera body, whether the body has a focus motor or not, because the lens itself controls the focusing function."

AF-S will override screwdrive.

Af-s lenses are much quieter and faster in my experience but its nice to have the flexibility to use any auto focus lens you like if the body has screw drive.
Also, the D50 has a motor in the body. Cheap as chips and a good beginner body.

I have three AF-D primes (24, 35 and 85) and a single AF-S prime (50mm).

Whilst I like the fact that nothing external moves on the AF-S lens, and that it's quiet, I actually prefer to use the AF-D lenses. The main reason is there's a tiny bit of feedback which you can feel when they hit focus. Sounds silly, but it's something that works really well for me.

Ah yes, a 'thunk' instead of a 'beep'!

The AF-D primes also have the advantage that with the manual aperture ring you can use a cheap reverse adaptor to turn them into a sharp manual macro lens on a budget.

If you want to put it that way, but the point I'm making is that you can feel the lens hit focus rather than rely on an audible (and stupid) beep. For me, that's a huge plus.
