Ah sorry, I was in a hurry when I read your last post and didn't catch that "as well" part. Thought it was the the combination of manual lenses and those modes.
Originally posted by enoeske without the electrical contacts in the lens to tell the camera about the aperture and focal length, the flash cannot use ttl data to automatically adjust the power. Therefore, with K or M lenses, the pop up flash just blasts at full power at front curtain. Not sure what you were expecting with respect to wireless if you are only using the pop up...
But adjusting the power of the flash automatically is in my opinion irrelevant to it firing at the rear curtain. The power can be set manually right? Or is the +/- just some adjustment of an automatic value? Anyway, if it cannot use ttl and thus fires at full power, why should it not be possible to fire at full power at the rear curtain? If it is only the lack of electrical connections then this is a firmware problem that can, but probably won't, be fixed in future firmware updates. It's just a matter of when the flash should fire, not if it fires at the right level.
Regarding the wireless mode, I am very aware that the pop-up flash is situated on top of the camera and that the two are actually physically connected. But I ask because I cannot select wireless mode, regardless of the flash I would be using.
