Can anybody explain me what is this feature = how is the camera behaving when using it ?

Thanks in advance,
Ruben

PS: I warn you I have quite a flat head for these sort of things.

It sounds like an auto mode for a daylight fill-flash. There is one fly in the soup, though. Yashica may have had a particular proprietary flash unit in mind to use with this feature.
 
Yes it has, like with a Canonet QL.
If tell me about slr TTL fill in flash at daylight, I understand what is it. But with Yashica GX - what the hell they are talking about ?
 
It is after reading the manual that I posted the question. At the manual they tell you do this and that, but no explanation whatsoever about what the camera is doing at "daylight synchro" flash.

Since the flash has a single power output the inference is that the f/stops will vary according to distance. Fine, but what is hapenning with the speeds ? Are they too varying accordingly and all these taking into account both flash power and ambient light ?

:bang:

I see your problem now. :)

The GX is a lens shutter camera, so shutter speed should not make any difference to exposure (someone correct me if I'm wrong please). I assume the manual is only a rough guide anyway.

DAYLIGHT synch :bang:
 
Upon reading about the Hexar AF at Cameraquest, I propose the following speculation about the "daylight synchro" of the Yashica GX:

a) When you set the f stop ring at the "ray" mark, the camera behaves as a normal Guide Number featured camera. This means the aperture will change according to distance.

b) When using the dedicated flash for the GX (which one ?) the extra pin at the hot shoe will tell the camera what GN is to be used.

c) The light meter sensor of the camera will meter the daylight situation, and according to the f/stop selected by the distance (based on the GN), the camera will select for you the according shutter speed, thus producing a perfect "daylight synchro" flash compensated exposure.

What do you think ?
