N80 - Focus Priority?
I recently bought a Nikon N80 and noticed a few times that it wouldn't shoot sometimes when I press the shutter release. Upon a little experimenting, it appears it won't shoot if it doesn't detect accurate focus. Is there anyway to change this in camera to a release priority rather than a focus priority? I can't seem to find anything listed about this in the custom settings.

To get shutter priority, you need to change to Continuous Servo AF (pg. 38 in the manual). This will allow you to shoot even if focus lock is not achieved.
If you subject is moving, then also select the dynamic area mode on the back of the body. CSM option 10 will also allow you to enable the closest-subject priority if this is desired.
Alternatively, if your shooting aperture permits sufficient DOF, and your subject distance does not change, you can simply change to MF mode since you do not need a focus lock in this mode either.

Caveat: enabling Dynamic AF and Closest-Subject Priority (CSP) can and usually *increases* AF calculation time and shutter release time. To get to a true release priority setting - Set AF to Single-Area, disable CSP and set Servo to C. Use the center sensor only since it's the most reliable. You've then removed a) any possible latency from Dynamic AF having to calculate which sensor is of interest and b) CSP from possibly locking on to a subject or foreground item that momentarily enters the frame between you and the main subject. The additional steps you need to follow are to practice locking on with the center sensor, half-pressing to enable AF and keeping it half-pressed with the sensor still tracking on top of the subject until you achieve preferred framing, then completing the press to fire the shutter. Takes a bit of practice, but it really is the least latency mode - I've worked this technique on N/F65, N/F80, D100 and D70 for years now.
