Hello all

I was wondering if any of yuongnuo 560 users have tried trailing sync with a pentax K7? And if it works?

Thanks

I have an YN-560 II. If that model is of any interest to you I can try to test it out.

I was first going to answer with a "I don't see why not," so I tried it on my K200d - didn't work - the camera doesn't have it as an option, so the flash needs to have it (or TTL), and the YN560 doesn't. In my reading, however, it sounds like the k-7 can be set to trailing curtain via menu.

IN other words, it won't with the k200d, it might (I'm guessing probably) with the K-7. I think a quick forum search might reveal the answer "k-7 trailing curtain" or similar.

I believe trailing curtain sync is a dedicated feature so it won't be available on any non-pentax flash (unless the flash speaks pentax!).

My 460-II manual states that "Your camera must support the rear curtain synchronization function of non-TTL flash". I can't help further though, because I have a K-x and I have to consult my own manual too.

Manual YNs (560, 460) does not interact with Pentax cameras. Therefore, if they are mounted on the camera, 2nd curtain sync option would not be available.
But. YN-560 could be placed off-camera & be triggered with in-camera strobe. Thus, if your in-cam strobe could be trailing synced, it may successfully lite off-camera YN-560.
As I have only manual lens, my in-cam strobe cannot be set to the trailing sync mode, so I cannot test this assumption with K-7, sorry. Though, on my Oly E-510 it works with some limitations described below.

You have to keep in mind, that in-cam flash would fire TTL pre-flash with 1st curtain. Thus, YN-560 in S1 mode will fire twice. In S2 mode you'll find yourself restricted to ~ 1/13 sec. of exposure or less.

1/10 sec., YN-560 in S2 mode didn't fire: http://desu.org.ua/pf/2012/_6053431.JPG
1/13 sec., it fired: http://desu.org.ua/pf/2012/_6053432.JPG

Maybe external optical slave sensors could help a little more with long exposures.

Thanks all for the replies.

Tsukiouji yes I was interested in the YN-560II and thanks for the info.

Guess there are some things that you can't do with a cheaper flash... oh well

If you're looking for a cheapish flash that does work with trailing sync on the K-7, the Cactus AF-50 for Pentax works. I believe I paid under $150 for mine. I've been pretty happy with it so far.
