I have a question which many of you may think is mad but I need to know. Also my Thom Hogan D70 disc won't uncrypt? so I'm well and truly stuck! I have a D70 with the kit lens (18-70mm) which is fabulous so far but I'm not sure how to use it all yet. How do I set the shutter and aperture, (when I move the lens the f numbers jump about)? What do the distances on my lens mean?(infinity and then feet and metres). I am a recent convert to SLR so its all still sinking in. I have just ordered 123 of Digital Imaging so I'm sure I'll be an expert soon but a quick tutorial in the meantime would be great!
Thanks a million,

I know nothing of Thom Hogans disc but do like his site.
You set the shutter and aperture on the camera body as described in the D70 manual. You don't need to set anything on the lens itself.
When you move the lens the f number jumps about because it does not have a constant aperture. A 70-200 F2.8 has the same max (F2.8 here) aperture at 70 mm and at 200mm. The 18-70DX ranges from F3.5 to F4.5 or something like that. It means that at 18mm the max aperture is F3.5 and at 70 the max is F4.5. So when your camera shows F3.5 at 18mm and you zoom in to 70 the aperture on the lens chanes to F4.5 and the lens tells that to the camera. The camera adjusts the f number in the LCD. Once you use higher F numbers it won't happen.
The distances on your lens tell to what distance the lens is focussed. Can be useful sometimes. Turn the manual focus ring to see what happens.

on the d70 m= manual - use both dials on the grip of the camera to set
a=aperture priority - use one dial to set aperture-best shutter speed is selected for ya
s=shutter priority - use dial to select shutter speed- best aperture is chose for ya
hi=pic will be overexposed, lo=underexposed

its all dependent on the situation/effect you want. i'm no pro but i prefer, and i know alot of pros do, the aperture priority- for most occasions. It lets you control DOF. most pros, ive read, use either manual, aperture, or shutter priority, shying away from the pre-programmed scene modes. those are only a part of all the settings that can go into your photograph though
