metering with Nikon G lens on SLR

[ongakublue]

hi folks

will a G lens meter on the F801s? I looked at Ken Rockwell's break down and it says aperture priority won't work cause of course you can't set the aperature on the lens nor will it read it from the lens. It seems manual doesn't work either which leads me to believe that the meter also won't read. i mean, the little scale that you need to centre.

second thing, the lens in question is a DX lens. If I put this on the F801s then there will be vignetting?

thanks for your help

How much vignetting will depend on the particular lens. My 18-70 vignettes at all focal lengths but my 17-55 can be used from about 28mm upwards.

The G lens will work in S or P modes only on the F801s.

Thanks. It's a 35mm 1.8 DX. You say S and P work and what about the light meter? does it read? I suppose it has to.

Just put the lens on and see what it looks like in the viewfinder. It's an SLR. If it's going to vignette I am sure you would see it. The camera has a finder w/ somewhere between 92% and 94% coverage.

Since you cannot change the aperture on the lens, if your camera can not change the aperture, you will only be able to shoot wide open.

I own a N8008, which is known as F801 outside of the USA. Lens compatibility is the same as N8008s/F801s.

I don't own the lens in question (AF-S 35mm f/1.8G DX), but I do own other AF-S G lenses.

AF-S G lenses will mount and meter on the F801s.

It will not auto focus, but you can focus manually.

It will work as expected in S and P modes, where the camera body selects the aperture.

In M and A modes, you cannot select the aperture. The lens will be fixed at the smallest aperture. The meter will work just fine, but you will always be at f/22. Perfectly usable in bright light, with a strong flash, or non moving subjects and a tripod.

With the 35mm DX lens, there will be some vignetting (slight darkening of the corners), but surprisingly this particular lens has almost full coverage of the 35mm frame. Some DX lenses are OK on 35mm, others are not.

Not quite correct - with a G lens, if the body cannot set aperture you can only shoot fully stopped down (highest F number). Metering will be wide open, but when you shoot (or press the DOF preview), the aperture will close to it's smallest diameter.

If the body supports S and/or P mode, it can automatically set the aperture as expected. M or A mode will be stuck at smallest aperture (highest F number).

EDIT: This applies to AF bodies. MF bodies and G lenses basically don't play well together.

OK thanks everyone. I am going to get a 50mm 1.8 AF D instead. I know it is a different focal length but I believe better for my needs.
