RE: Question: P-TTL and Digital SLR
The reflectance of the imaging device (CCD) is much different than film. This is the reason that Nikon had to revise the SB-28 flash for use with DSLRs. I believe that the final flash meter reading is taken from the front of the shutter curtain. From: Patrick White Um.. did I miss something? Why is this a requirement for flash on a digital camera? Can't they use the equivalent to OTF sensing too? - This message is from the Pentax-Discuss Mail List. To unsubscribe, go to http://www.pdml.net and follow the directions.

Re: Question: P-TTL and Digital SLR
Speaking of which, it seems that P-TTL is a requirement for decent flash metering on digi-SLRs. I imagine the MZ-D (rip) is the reason we have this. On another topic: 31mm x 1.6 = 50mm Food for thought.
