Will a YN-560 Flash Blow Up My K-x?

Looking for a Flash... Poor... Same old story... Will it kill my K-x if mounted to hotshoe?
If it will...
Would a wireless trigger kit make it not? (kill my K-x)

There appears to be only limited info on this flash and can't seem to find any reviews that link the unit specifically to pentax cameras or the K-x in particular...

I know I should probably wait and get a Metz-AF58(or 48) but at more than twice the price and (again) being poor...

But is anyone here using a YN-560 with a Pentax K-x?

What do you mean by kill the Kx?

I have an AF-360 FGZ with my Kx but after deciphering the flash user manual I don't think it's a compatible flash, unless you want to do it manually. Seems like it works only with 66/67 and 35mm film Pentax.

I'm not really sure, though. Consequently I've used the thing like twice but didn't know what I was doing so really I mounted it a few times and took some throwaway pics. I've got a lighting class next semester at school so hopefully I'll learn more then. But I have no idea what to do with this flash or other flashes with regard to the Kx. I'll be interested to hear what people say.

In the meantime what do you mean by kill/blow up your Kx?

Honestly... I'm not sure... I remember reading something (that I can't find!!) about a flash-gun 'frying' the circuits of a guys camera... It was a different model to the gun I just ordered but by same chinese company...

YN-560... (Cheap!)

Should arrive in the next week... from what I can tell it's a 'manual flash' although to be honest... I'm not altogether sure what thats going to mean for me... Guessing I'll just have fun trying to get it to work (in scary alleyways and dark city streets) is all :-p

You should be fine. Look in the field accessories forum for a recent thread about Youngnuo.

Someone posted a link to this site: YN-560 Specifications and Test Results | Speedlights.net

Trigger voltage is what you're worried about. 3.25 volts is safe

Older film flashes could, if used on a digital camera, cause the problems you're talking about. I have an old Vivitar Thyristor that puts out more than 8 volts (tested with multi-metre). I'd never use it with any digital camera or wireless trigger/receiver though. But it does work fine with my spottie and ME.

Are you aware that it is a fully manual flash?

No P-TTL, no auto-thyristor, no AF-assist, etc.

There is a good amount of information:
Flickr: Search Strobist.com
Yongnuo YN-560 - Canon Digital Photography Forums

If you want cheap P-TTL, there were some being mentioned on the forums, I think these are it:
https://www.pentaxforums.com/forums/pentax-camera-field-accessories/49880-dig...ed-tested.html
Sakar Models, Under Many Names - Pentax P-TTL Flash Comparison

You can get auto-thyristor flashes for even cheaper, like the AF280T.

That said, I will probably be ordering 2xYN-560's or one YN-560 and one YN-460II for off camera purposes.

Hi Dave,

I have the YN-560 and a Metz 58 AF-1. The Yongnuo works fine for on-camera flash on my K20D ("fine" as in, it fires) and I'm pretty sure I tried it out on the wife's Kx without any dramas as well. It is a fully manual flash, so be prepared to use your camera in M, adjusting the shutter, aperture and flash strength to suit (possibly changing) conditions.

Both flashes work great for off camera flash stuff (I'm using Cactus V4 triggers), where perhaps the YN-560 actually has a small advantage as it's quicker to adjust power settings (have to dig through menus with the Metz) and has a very functional slave mode in case of trigger trouble. The Metz is certainly more powerful, but I rarely if ever am firing them at full power anyway.

For on-camera stuff, it is nice to have the features of the Metz (high speed sync, P-TTL, etc) and I'm not sure of the prices for the gear over there (I got my YN560 for about US$65 here in HK), but I'd say overall (for me) the YN is the one to go for.

Good luck!

Cheers,
Joe

I have three YN-560 flash units, and their trigger voltages are 3.25V, 3.26V, and 3.29V, so as far as being safe to mount on the hotshoe of your K-x, then the answer is yes.

Hey all!

Cheers for all the replies! Muchos helpful!

@ Eruditas... Yeah... I realise that it's manual... Figure it'll just take me a while to get a system going for the right exposures in particular situations... All fun!! :-)

@ Lowspark86... Yeah trigger voltage was deffo what I was worried about... am I going to have a problem with "YN-04" flash triggers with the same regard?

@ JoeGray... Cheers man... The Metz is slightly out of my (student) price range. Got the YN-560 for 60(UK) and free postage... The YN-04 triggers were 13 free p&p...

I shall now be found with my face in the 'Strobist' website until new toys arrive!

:-)

Thanks again, you're a lovely bunch!!

Hi again...

One more question (OK two...)... Related... I think...

If I'm using wireless triggers do I still need to worry about the flash's output voltage?

If not... Does that essentially mean that... If using a wireless trigger/s I can use any flash, from any brand/company, and of any age without fear of blowing up my camera????

There's probably a better way for me to have phrased that... Hopefully you'll get the point...

Advance Thanks
Dave

You'd still have to be careful with trigger voltages depending on the triggers themselves, as some of them can't handle high trigger voltages. So a flash unit on a wireless receiver that can't handle the voltage would most likely lead to a dead wireless receiver.
E.g. the RF-602s are not able to handle the high voltages of some of the older flashes.

If the flash is not physically connected to the camera in any way, then you have no fear of blowing up the camera. However, like I mentioned above, the flash could potentially fry the wireless receiver it's connected to.

I use the AFG-360 with my K200 and I assure you it is not meant just for film. It is an EXCELLENT strobe and works in manual, TTL, and P-TTL both on and off camera. Pentax may not have the "system" that Nikon and Canon have but you can do off camera flash much easier and cheeper.

@Dave - I have 4 Promaster "film" flashes with Pentax modules. They work great both on and off camera. I got them all New In Box (New old stock - I think they were part of Ritz stock) for less than $80 (3 x 6500, 1 x 5500). Check around, you might be able to get a TTL for less than the YN-560.

Help please

Hi Dave and other bros,

I just got my YN560 and RF-04II for my K-x.

I was comfortable with the trigger voltage of 3.xx V of the YN560 and tried on my K-xit worked fine.

I am new to strobes, my next question might be silly.

I did see the RF-04 trigger's voltage mentioned as 12V on the package, would this hurt my K-x circuits if i mount the RF-o4 trigger on the hot shoe. not gonna try until i get some word from you guys....

Please share your experience and any known issues or tips with the RF-04 / YN560 combo.

thanks,
arun

I have zero experience with the RF-04 wireless triggers, but my educated guess is that 12V is the maximum trigger voltage that the RF-04 can handle. I.e. the 3.xx volts of the YN506 will be safe for the RF-04; but use an old school flash with a >12V trigger voltage, and you could possibly fry the RF-04. That's my take on it, though I'd get a 2nd, or 3rd opinion, just to be sure
