I've seen a thread about this flash on older Pentax DSLRs, but does anyone know it it's compatible with either the K20 or K200. I'm not sure what difference having P-TTL or TTL makes. A real novice with flash!!!

Cheap/plasticy feel. Doesn't seem to work on digital SLR cameras.

I think its fully manual on the K200D/K20D so you would fire on full power (unless the flash has power settings?). You would have to alter the brightness via aperture.

I may be wrong but thats how I use an small old normal TTL flash I carry.

I have one of these and it works just fine (although it is definitely cheap and plasticy).

Just goes to show you shouldn't believe everything you read on the Internet

It supports TTL & Manual (at full power flash), but not P-TTL.

So on my *ist D you get full automation.

On other Pentax DSLR's you have to use it in Manual (ie vary the aperture & ISO to get the right exposure).
Given this is used for Macro where you tend to be a consistent distance from the subject, I haven't found this much of a problem!

I've plumped for a Sunpak DX8R Ring Flash to get me started, as it was new from Devon Cameras, just waiting for the Pentax Shoe Module to arrive from the USA. Reading the Manual it has three modes Manual, Auto, and TTL. I understand TTL does not operate on K200 and K20, but what should I expect to happen if I set it to Auto.

Generally, a flash having one or more 'Auto' settings has a built-in light sensor to control the flash duration. This in turn controls the exposure.

Does that mean you can set any aperture and shutter speed and the flash unit compensates itself? That sounds too easy!!

I've just picked up a GX8R sunpak, though I have no manual for it, dont suppose yours covers that one too does it barrie? (probably not as the Gx8r is a bit long in the tooth now). Running mine from the pc port (as its voltage protected there) and seems to fire fine but i'm compensating manually in camera at the moment (or turning the flash output down.)


EDIT: forget the manual request Barrie, just looked up the Dx and its totally different from mine - very much more modern!

No, the flash will tell you to set an aperture relative to ISO so, for example, 5.6 @ 100ISO and 8 @ 200 ISO and so on. Having done that you just fire away.

The flash manual talks about setting the camera shutter to the flash sync. speed. In the K20 manual I can only find reference to the sync. speed for the built in flash, is this the same for external flash units?

Does that mean I can not use it on the K200 with no 'X' on the dial?

Sorry I misread your post, I thought you had a K20. Anyway just set it to Manual and use 1/180 and whatever aperture the flash suggests.
