But it won't drain the battery from 100% to 0 in a day.
I must admit: not from 100% to 0% in one night. I had taken about 15 photos and during the following day the battery was suddenly empty. Fact remains that IMHO the adapter drains the battery much quicker than with FE lenses. But it also turned out that "Remote Ctrl" was turned on, active apps are also known to drain the battery.
Originally posted by KoenR Not even unmount. Unlock the mount, turn the adapter 30° to the left (facing the camera), wait a few seconds, turn back until the adapter is locked again. That is enough.
Meanwhile, I did some testing with the Monster adapter: I left the camera with a fresh battery (100%) after I applied the workaround. Turning the camera on again after 5 days: still 100%.
Until now I have tested the following:
- SMC Pentax-FA* 24mm F2 AL [IF]: AF OK (wow!)
- smc PENTAX-F 28mm F2.8: AF OK
- SMC Pentax-DA 35mm F2.4 AL: AF OK
- smc PENTAX-DA 40mm F2.8 XS: AF OK
- smc PENTAX-D FA Macro 50mm F2.8: AF OK
- SMC Pentax-FA 50mm F1.4: AF OK (!)
All of the above EXIF including chosen aperture (set with camera) and focal length
- SMC Pentax-FA 24-90mm F3.5-4.5 AL [IF]: NO AF but MF (focus peaking); EXIF including chosen aperture (set with camera) and focal length
- SMC Pentax-F 1.7x AF Adapter + SMC Pentax-A 50mm F2: NO AF but MF (focus peaking); EXIF including chosen aperture (set with camera) ; but focal length NOT transmitted.
- SMC Pentax-F 1.7x AF Adapter + SMC Pentax-M 150mm F3.5: does not work !
