Hello Massao
Here, in Norway, I found these flashes for sale:
Sigma EF-610 DG Super
Sigma EF 530 DG Super
Metz 44 AF-1
I’ve been reading on internet about the issues with Sigma flashes. It seems I should avoid Sigma because they cannot be updated by users, so If I buy a better Pentax DSLR in future, it is possible that Sigma flash wouldn’t work.
On the other hand, Metz can be updated by users, so no matter how old the flash unit is (released with P-TTL for DSLRS), it can be updated for future Pentax cameras.
Please correct if I am wrong
I did never had a Sigma flash, but I know that you can send in your flash to Sigma and you get on this way your flash up to date, if possible.
With a Metz flash you can do that for yourself, when:
- the flash has a USB interface ( new Metz flash have it, but always check that)
- Metz do publish a software update for your (than) elder flash.
- Pentax do not change too much in the flash protocol, so that an elder flash can get via a software update up to date to this new generation cameras.
Some flash (also some Metz flashes) do not fully support all the flash functions, a Pentax camera can has.
The restrictions are often find in the wireless use of the flash:
- some flash do not have a wireless P-TTL HSS mode ( or even have no HSS mode in generally)
-some flash can only act as a slave in the wireless mode, but not as a master or controller (on the hot shoe)
BTW: I love to use a flash when I take pictures of my children at home .... and use a foil when needed :-D
When I bounce the flash, it can happens that under the eyes, you get some shadows, so maybe look at a flash, which has a built in bounce card. Via this little built in bounce card you send a little direct light to the face and that soften and illuminate a little the shadow lines, you get via the bounced main flash. My Metz 58 AF-1 has a second flash tube, so that I can do send this direct light via this second flash tube, meanwhile the main flash is bounced, but not straight...and maybe a little to the side, so that the use of a bounce card is not possible, because it looked not direct to the face than.
Ok, I did also played with a bleach bypass in PP here.
