PTTL Flash for Pentax K-x

I am sure you get this question multiple times. Unfortunately may adds are misleading. What third party flash units are true PTTL dedicated units for Pentax DSLRs ? What is the difference between TTL and PTTL dedicated units?

The only true after market flashes that will work 100% are the ones from Metz;

I have had good success with Sigma flashes on compatible DSLR's but I would not say they work as the manufacturers flashes.

Per Pentax:

PENTAX P-TTL units (AF540FGZ, AF360FGZ, AF200FG, AF160FC) use a pre-flash which bounces off the subject, passes through the lens (hence the “TTL”) is measured by the camera and used to control the output of the main flash pulse which follows.

PENTAX TTL units (i.e. AF500FTZ, AF400T) do not use a pre-flash. The main flash pulse bounces off the subject, passes through the lens (TTL) is measured by the camera, and when sufficient exposure is reached, the flash burst will be shut off.

All of our current and recent DSLRS are P-TTL or Manual flash exposure only. They do not support TTL flash. If a TTL flash is used on one of our DSLRS, it must be used in Manual flash mode or in the flash’s “AUTO” mode (if it has one).
