I apologize if this has been answered somewhere before, but I searched the forum (and the web) and cannot seem to find my answer. I purchased a Leica SF24D about a year ago. On arrival, it worked flawlessly in TTL, A, M etc and overall I was pleased.
It has been a few months since I have used the flash and this past weekend when using the unit, it noticed that it exhibited some behavior that I do not recall existing before. When used in TTL (and with 6 bit coded Leica lenses ) I thought I remember that when changing the F-Stop on the lens, the flash would also show the corresponding f-stop with distance on the LCD display on the flash . When using the flash this past weekend, I noticed that when changing the F-Stop on my lens, the flash was fixed on an f-stop, say 2.4. When I changed my lens from 2.4 to 8, the flash remained on 2.4. Overall, the exposure actually looked correct so it appears that that the flash is working. As a test, I adjusted ISO on camera and the ISO did change on flash. I also changed sync speeds in camera, cleaned contacts on lens, replaced batteries in flash etc. I also manually adjusted flash f-stop when in TTL mode (set flash to F8, then lens to 2.4, 5.6, 8 etc) and the exposures continued to look accurate.
Am I just remembering the operation of this flash wrong? I thought the flash f-stop would show the corresponding f-stop on lens when in TTL?
As for A, that is working as expected, same as M.
Thanks for any insights.
