Light in LCD: Its the same on my K-7. I think it is synchronized with the light in the lcd on the camera. Try to turn of the light in the custom menu.
Exposure: Your *istDS have a base iso of 200 and your K-7 a base iso of 100. When testing, do you have both cameras on the same iso value? Diffusors and bouncing are stealing a lot of light. Are you sure your flash is powerful enough. Try increasing ISO. I am almost always using ISO 200 to ISO 400 when using a flash. My own impression is very good results with this flash on K-7.

I am still trying to figure out how AF 540 FGZ is supposed to work with K-7. I see several strange things: 1. When the flash is mounted on K-7, whenever the camera is in the metering state, the green back light on the flash stays on, and I cannot turn it off by pressing the "light" button. I just found that the only way to turn off that light on the flash while K-7 is in the metering state is to have K-7 in M,B, or X mode, switch the flash into A-mode, and push the button "light" to switch of the light. This is not how the flash behaves on *ist DS. Could somebody please confirm whether K-7 + AF540FGZ indeed behave this way? 2. AF540FGZ in P-TTL modem, when the flash is directed at the object, produces shots that are between -0.5 to -1 stop underexposed, if at a distance of more than 3m (10ft) Using a reflector (I've been using the Lightsphere Cloud ),- doesn't seem to provide adequate metering: all shots are 1-2 steps underexposed. Using the bounce card on the flash also leads to great underexposure, - even within a rather small room (I tested in the bedroom). Using the same flash with *istDS produces very consistent results with and without Lightsphere Cloud. Can anybody confirm that the combination of the AF540FGZ and some type of reflector on K-7 produces different metering? Thank you in advance! I suspect if something is wrong with the K-7 (or the flash?), and I need to exchange them for a proper unit, while I can. With all of that I seem to be able to confirm that there is preflash. My eye cannot notice it, but I confirmed that I can see a flash through the viewfinder, which, if I am correct, indicates the preflash happens (i.e. it happens before the mirror is down). When I am shooting in the A mode of the flash, I don't seem to see the flash through the viewfinder. Igor PS. On top of all that, the flash head has a problem that it does not go into the full straight position. Weird... I'll need to exchange it, - but I am still trying to figure out if I should do the same with the body. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
