>Using the 300 F4, TC 14B and an F70 my display blinks F - -. This is on A, >S, P, and M. >What is the reasoning for this ith the TC 14 B? Sorry to say that, but the TC14b is a MF TC. That is, you can't use it in S and P mode and you loose aperture display and matrix metering. Still, the optical quality is very good. Time to practise the A or M mode and your center-weighted metering skills ;-) Nicolas
