might there be anyone in nyc willing to teach me how to operate my newly-acquired F4s?
Intitially, please answer these queries:
1. why would i set focus mode to 'manual' if i am using an autofocus lens?
2. what is meant by "maximum aperture slower than f/5.6"?
3. "aperture" versus "effective aperture" == ?
4. how to use diopter.
5. autofocus modes: when to use "single servo" and "continuous servo"?
... and many, many more!
