The original post seemed to imply that the camera was an F3 which uses a TTL flash system different from every other camera (Nikon et al). I never used TTL flash with my F3 so I cannot comment on the what nor wherefore. As far as my extremely limited knowledge goes. The SB28 cannot be used as a TTL flash with the F3. This may well explain why it is not working nor recycling properly." Excuse me for this OT mail but it seems that someone is interested in SB 24, 25 ... flashes in Nikon F3. They can actually be used TTL with accesory AS17 which merely drives signal from the camera to the flash. F3 uses same general metering cell for mastering the flash and general metering so you cannot have sametime metering from flash and from ambient light as more modern SLR flash management which take account of ambient light for dosing flash light. Recycling time depends only of batteries charge not of flash mode. Anyway TTL consumes less energy that automatic so perhaps condenser is not fully discharged. But this is in opposite senseso that TTL had to have shorter recycling times. I hope this help Reamining on topic I've ordered two months ago a Summicron 28 f:2 asph. You know if delays are really longs? Kind regards Félix
