Metz announcement on 16 February: Users of Metz flash units with Pentax Kr and K-5 DSLRs can download a Metz firmware update
here for improved functionality, described on their English language site as:
1. Servo mode with preflash suppression possible.
2. EV correction remains after power off/on.
3. Rear function with Pentax K-r and K-5.[/I]
No 3 above is not very clear due to losing something in the translation of '2. Verschlussvorhang mit Pentax K-r und K-5' on the German site.
Verschlussvorhang is shutter-curtain so it is most likely rear(2nd)-curtain sync functionality for the Kr/K-5 that has been added. Does anyone disagree?
There have been a few posts on other forums to suggest problems of over-exposure with the Metz 58 AF-* when used with the K-5 for
bounce flash but it has also been reported that downloading the firmware update appears to have addressed that, although it is not specifically mentioned on the Metz download web page.
Bump
Edit: I just checked the German language section of my Mecablitz 50 AF-1 operating manual and found that '2. Verschlussvorhang' is indeed rear(2nd)-curtain sync.
