Hello all,

I'm a relatively inexperienced SLR-user, I have a D50 which I'm ashamed to say has been mostly used on autopilot over the years. I'm now trying to learn the intricacies of shutter, aperture etc, and I was hoping someone here could explain a couple of things that don't make sense to me.

First of all, what decides how big of an aperture you can get - the lens or the camera body or both? I have a Nikkor 18-55 AF lens and the numbers on it say 1:3.5 - 5.6G. This is aperture, right? (Shouldn't the letter at the end read F then??)

Anyway, I tried adjusting the aperture in Manual mode - but the biggest aperture it would give me was F 4.5 (down to 29). Why will it not go to 3.5 as it says on the lens?

Thanks in advance for any answers!
