Similar to the K30 and off-camera flash overexposure, I have found the K50 does the same in TAv mode. I quite like the camera and have to agree with the PF in depth review in all other respects.
Has anyone run into the same issues with the K50? There are 2 main things I've run into.
1) Firstly, flash won't even work with the AF360FGZ. I have to use the AF540FGZ.
2a) Changing the flash mode out of P-TTL or dialing in lower flash comp (on the 540) still results in overexposure. This happens in indirect & direct flash uses.
2b) And here's another twist... at close and medium distances using flash causes massive overexposure. At telephoto distances there doesn't seem to be problem. As you can see from the test pic below, the ISO drops down nicely to 4500 when at short telephoto.
Can anyone explain?
2c) Switching to Av fixes the problem, but the shutter speed seems to default to the lowest ISO setting. It's a pain to dial the ISO from 100 where I usually have it to something higher as I find the shutter speed is still a bit low even with SR.
2d) Switching to Tv also fixes the problem. I have to keep it under 1/350 to prevent underexposure even with the flash set on HSS.
2e) Switching to M/M fixes the problem as can be seen in the pic below. The test subject is my oldest son.
