Nikon N70 won't fire with a Nikon AI lenses in Manual mode.

So, I took my N70 out to shoot some pictures the other day and discovered that it refused to fire in Manual mode with my Nikkor AI 50mm lens. I've tried it with a Nikon AF D lens in both AF and M mode and it works perfectly. At this point my solution is to just use the AF lenses exclusively, but I really like the pictures I get from the old AI lenses and the N70. I've also tried the AI lenses on my N90s with absolutely no issues. Anyone got any ideas?

I can use just about any Nikkor on my N90S bodies. How do you normally set aperture on AF lenses with the N70, with the aperture ring or a command dial of some kind? If it is with a command dial then you probably won't get it to work with an AI lens.

I use the aperture ring to set it. And if I am remembering correctly, I used the AI lens to shoot with this camera before with no issues. The manual tells me that the AI is compatible with the N70, and that all I need to do is select manual and it work. Oh well.

I just pulled out an N70 and an AI lens. After I managed to get it set to M(no small task :) ) I had no trouble getting the meter to "center" and then get the shutter to fire.

 

That is with the caveat that there was no film loaded.

Is this one of the models that makes you close down the aperture on the lens all the way?

I don't think so. It has an AI tab, and also no provision for DOF preview. In fact, even with an AF lens, you have to use the aperture ring to set the aperture in A or M mode.

 

I was using mine earlier wide open since apparently the stop down lever is bent and wouldn't stay open.

Problem solved, I had to change the metering from matrix to either center weighted or spot metering in order to use the AI lens. Works perfectly now!
