- My sincerest apologies. I recall reading this in one of the British
- photo magazines. I have now picked up an F-90 brochure and will study

- Though my original assumption about lens-integral motors was incorrect,
- the local dealer does say that the AF-D lenses are more expensive than
- the original AF. So it's still true that N8008s owners pay for a
- feature they cannot use, whereas EF lens integral motors are usable by
- all EOS bodies.

- There was a thread not too long ago about how one Nikon shooter found
- that matrix metering didn't give exposures significantly different from
- centre-weighted. I don't have a body that has both metering systems
- for comparison purposes, but it would seem to make sense. Most multi-
- segment metering systems *must* emphasize the centre segments because
- the AF sensor is there. This is probably true for OTF metering too.
- When cameras can determine where the subject of interest actually is,
- they will all be limited in this way. (The A2E certainly is a step
- towards this.)

- Some of the other SB-25 features are very nice. I'll pick up on that
- in the next message.
