Hi all,
I've been really frustrated with the PTTL performance lately. Trying to shoot a party in a night-club. Faces get randomly overexposed! A HUUGE dissapointment! When testing at home, I also get different results, depending on bounce/nobounce and amout of white color in the frame. One thing is for sure: when bouncing, exposure goes up at least 1EV. When there's a lot of white (walls and ceilling), then I get always about 2EV overexposed shots with bounced flash. When not bouncing, then getting even slightly underexposed when no white and normal when with white. This is a bloody riddle, I cannot solve... To me it just seems like PTTL is a bad piece of.... software
I'm praying PENTAX to solve this and save me the money of switching to canon!!
ps. firware is 1.11, flash is both: 540 and metz58 af-2, lens is DA16-50 2.8, I use Manual mode on camera (ISO 200, F2.8, 1/100), i tried other modes, don't see much difference
pps. at least metz works more or less fine in A mode. But 540..... it's amazing... in A (a-u-t-o-m-a-t-i-c) you need to set ISO and aperture MANUALLY! Also AF assist doesn't work!! Outrageous.
