TTL Flash for LX

LesDMess · 11-21-2011, 09:16 PM

I would like to get a TTL capable flash for my LX. I currently have the AF200T and will likely add the AF280T for added power and flexibility. I am really interested in the handle mount AF400T since I usually end up using a strobo anyway. If I want serious lights I do have some White Lightnings. Are there any others I should consider - more modern, off brand, others? TIA.

The 280T and 400T are great choices for the LX. The lack of P-TTL makes them less convenient for a DSLR. If you want to use the same flash for both types of cameras you could take a look at the AF540FGZ. On the used market you can find a bracket and flash grip so you can mount it on the LX like the AF400T.

If you want modern for P-TTL support the Metz 48 AF-1 (and probably all modern Metz flashes) also support both TTL and P-TTL. Of course, if you don't need P-TTL there are cheaper options.

AF500ftz should work great.

Can someone with an LX+AF200T/AF240T/AF400T and light meter please confirm their output?

I setup my LX at ISO100, 0 compensation, manual at X (1/75) and f5.6 with a 50mm lens. The AF200T/AF400T is setup at ISO100, TTL. When I fire this setup at a distance of about 5 feet from my Sekonic L358, the suggested f stop showing is f11 and of course I am expecting f5.6. I also fired the flash at various f stops and the output is correspondingly higher - at least to the max of the flash.

I suspect my LX flash TTL control is not working properly since I have two flashes giving the same output and I don't have another LX to try or another TTL capable Pentax body like the Super Program to verify intended functionality. I do have other manual focus flash TTL bodies/flash from the era that act as I expected. TIA.

Are you maybe trying this without film? If so, then it's expected behaviour, because the pressure plate is less reflective than film.

Thanks for reminding me as I always seem to forget that as the other two I tested are not OTF flash metering. I have used the combination with film and the results were overexposed but I will do the teest again with film.

Thanks to Drougge for reminding me of the LX's IDM (OTF) flash metering as I just got around to confirming that all is well. That is with film loaded, the output is what is expected.
