"Mounting AIS lens on D5100"


US
          

I have a 50mm f/1.8 manual prime that i mount to my D5100. My question is, how far do I rotate the lens to get it to mount? The kit lens rotates until it clicks, but when i rotate the prime, it seems to stop before that. I don't want to force it any farther, for fear of breaking something! Please give me any help you can offer.

When you mount the AIS 50mm f1.8 to the D5100, the lens aperture dot should fall directly under the K in Nikon on the front of the viewfinder housing. It doesn't matter what the aperture is set to, the dot is under the K when it clicks in.

Just make sure the aperture lever on the back of the lens springs back nicely when the lens is set to f22 so while looking at the blades they open to wide open from the nearly closed position when you press it with your finger. Also look for any damage to the mount.

Thanks Leonard! Mount looks good, but it seems very tight when it gets to the "N". I afraid to rotate it that far. I'll take a closer look at the mount.

The dot should not rotate all the way to the "N", only to the "K".

Len

edit: It should look like this when the lens is locked in place and set to f1.8. The black dot is hard to see but it's directly in front of the 1.8

I was talking about the first N. Don't I line up the dot on the aperature ring with that of the camera and rotate counter clockwise? If so, I need to rotate past the first N to get to the K.

Yes that's correct. You actually go past the "n" small N. I don't know why it won't rotate further if everything looks good.

You may have this figured out by now, but...

I use the f/1.8D lens on a D3100. For mine to work, I must turn the aperture ring to F/22 and lock it in place. Otherwise it feels rough mounting it to the camera.

I'm not sure if the F/1.8 has an aperture ring lock on it or not. If not, just turn the ring to f/22 and leave it there. The camera will then set the aperture, same as a "G" lens.

Good luck,

Bob

Manual focus lenses don't have aperture ring locks like the AF-D lenses do. I have no trouble mounting my lenses where ever the aperture is set.
