Web Analytics RiceHigh's Pentax Blog: The P-TTL of the K-01 is even More Pathetic? (Or Is It the Silly Ambient Light Metering Instead?)

The P-TTL of the K-01 is even More Pathetic? (Or Is It the Silly Ambient Light Metering Instead?)

Read this latest K-01 user report (at the DPR) and it is soon learnt that the on-board P-TTL was doing a bad job for the daylight fill flash, everything is washed out seriously:-



The user then told that the camera was put in Full Auto. With an Auto ISO of 200 chosen (by the camera) together with an aperture of f/5.6, I don't think the result should turn out to be as poor as that, as for the flash settings. However, the 1/60s Tv seems to be rather low if the scene was actually brighter (if it was near the sunny-16 brightness, say). So, it might be the new super multi-segment "intelligent" ambient light meter (now under full Live View mode) has been fooled and went nuts and overexposed the scene so that almost the whole frame was burnt. Otherwise, once again the K-01 onboard P-TTL flash is really Pathetic, which could be even worse than the one found on our Pentax DSLRs! :-o

After all, the infamous Pathetic-TTL problem of Pentax will never end, as it seems to be! >:-[

metering from image sensor is always really slow, even my V1 which is doing 60 frames per second full resolution is sometimes slow to react to light changes. I really do not understand how they do it with flash, have not tried V1 add on flash yet.
I have had this happen on my K200D - images blown out as if the flash (AF-360) was on full power. In each case it turned out it was because the flash was not quite on correctly. Im talking a millimeter or two. Take it off, remount, good to go.
More samples now in this thread, + compared with m43. Seems to be PTTL problem.
Pentax will probably adress this issue, they aren't that bad.

I've had some pretty poor experiences with Pentax flash really it's probably the worst of all the makers out there so I'm not shocked at all by this.
Sure they might fix it, but it should not be broken anyway. You have to wonder what these dudes are doing the flash should be fairly consistent by now they've had years to sort this out
This looks great!
