Why won't the len's work for my Nikon D70?

I have a Nikon D70 i inherited from my uncle. It came with its normal lens, but also a Tameron AF 28-200mm LD lens, a Phoenix 100-400mm AF zoom lens, along with a few others. But whenever I attach the lens to the camera to use, it refuses to shoot a photo. I can't figure out why. They mount just fine. But refuse to take a picture. I found the manuals for the camera and the Tameron lens but its not seeming to help.Am I missing a button or something I'm supposed to push? I have a canon that I use regularly but I wanted to start practicing with the Nikon. I'm majoring in photojournalism and hoping to do action photography.It'd be nice to use the lens, or practice with similar telephoto lens, but i can't make it work.

Turn your focus on the body to M and try again - these lenses may not have internal motors, so the camera won't shoot, because it can't focus.

Are the lenses manual or CPU (look at the end of the lens that goes into the camera and see if there are any contacts)? AF lenses should be CPU, but you never know with inexpensive 3rd party lenses.

If so, you must use manual exposure (although your camera should give you an error if you need to go into manual mode).

Also, see if they are focusing properly by looking at the green dot (item #4 on page 8 of your manual). When the lens is properly focused, the green dot will be solid. If it is flashing, the lens is not properly focused.

If you can't get the green dot to come on solid, then switch the lens and camera to manual focus. The lens should have a manual/auto focus switch, and the camera has a manual/autofocus lever near the lens mount.

Or look to make sure the manual/autofocus switch on the side of the camera is in the auto position (item #64 on page 4).

The D70 was an advanced camera and it does have an internal focusing motor, so it should autofocus AF lenses.

If they are autofocus lenses with aperture rings, then turn the aperture ring to the highest f number. That tells the camera and lens combo to work together with electronic control over the aperture setting. Adjustment of the aperture to the other settings with the aperture ring is for older film bodies that do not electronically communicate with AF lenses.

If you're getting an FEE error or F--, set lens aperture ring to highest number and leave it there.
