Guest mc_k Posted November 27, 2009 Share #2 Posted November 27, 2009 SF24 I'm pretty sure Link to post Share on other sites More sharing options...
Guest mc_k Posted November 27, 2009 Share #3 Posted November 27, 2009 I think your choices are SF24 and SF58. And four Metz flashes with the appropriate module, at least on the M8, and I assume on the M9. But the Metz flashes are all bigger than the 24. I don't think TTL/GNC on the M8 has won many people over. Link to post Share on other sites More sharing options...
eritho Posted November 27, 2009 Share #4 Posted November 27, 2009 What about the SF20 and M9? Link to post Share on other sites More sharing options...
AlanJW Posted November 27, 2009 Share #5 Posted November 27, 2009 The sf20 works but no ttl. Works fine on "A" setting. Quite limited. Ok for very occasional use. Link to post Share on other sites More sharing options...

Why not on M9? I dont have my M9 yet so I cant try? Link to post Share on other sites More sharing options...
Guest mc_k Posted November 27, 2009 Share #7 Posted November 27, 2009 Advertisement (gone after registration) SF20 predates the M8. I think TTL for M8,M9 means a measurement from a preflash--quite different than your film cameras... Link to post Share on other sites More sharing options...
AlanJW Posted November 27, 2009 Share #8 Posted November 27, 2009 But SF20 worked by TTL on M6 and M7.Why not on M9? I dont have my M9 yet so I cant try? SF20 ttl technology is for film. Need somedifferent for a digital. But it will work just fine in A mode. Link to post Share on other sites More sharing options...

Could you please explain. I have the M6, M7 and is waiting for the M9. Do I need to buy a new flash? I dont like using flash and therefore use it very little and I'm not happy to have to spend a lot of money on another flash. I thaught TTL was TTL but apparently not Link to post Share on other sites More sharing options...
Jager Posted November 27, 2009 Share #10 Posted November 27, 2009 Thanks.Could you please explain. I have the M6, M7 and is waiting for the M9. Do I need to buy a new flash? I dont like using flash and therefore use it very little and I'm not happy to have to spend a lot of money on another flash. I thaught TTL was TTL but apparently not In TTL on a film camera, the camera reads the light off the film, using that information to know when to extinguish the flash. That won't work on a digital sensor. So digital cameras must resort to a "pre-flash" - a short pop of light which the camera reads to determine flash exposure - just ahead of the "real" flash. If done well, the pre-flash merges with the real flash and appears as a single flash event. The SF20 was designed for film, hence it has no pre-flash capability.

ho_co Posted November 28, 2009 Share #11 Posted November 28, 2009 eri-- No, you don't have to buy a new flash. The SF20 will work in Auto mode on the M9. Auto worked fine for a couple decades before TTL showed up. If you don't do much flash, I wouldn't dash out to get an SF24. SF20 and SF24 have identical power, but the SF24 has more aperture options and will work with GN/TTL or whatever they call the pre-flash mode of the M8 and M9. IOW, SF24 does more things and can do everything the M9 wants it to. But it's probably not worth switching if you don't do much flash. When the M8 came out, the pre-flash mode of the SF24 was woeful. That was greatly helped with a firmware update, but many SF24+M8 users still weren't happy, so they switched the flash to Auto. And that's exactly the same mode you'd need to use with the SF20. Only one thing: I don't think I've seen reports from M9 users with the SF24 to see whether it's better on the M9 than on the M8. Since the M9 has more processing power than the M8, it's possible that the flash setup is better. I doubt it, since Leica would likely have told us if they had improved the camera's flash circuitry. So keep your eye out for an SF24 at a good price, but in all likelihood, the SF20 will work just as well for you. Link to post Share on other sites More sharing options...

I do still not understand, sorry but that might be just me. Normally the light is measured through the lens also by M8 and M9, I presume. Normal light woundt do a pre-flash og pre-light, but it works? What is it I dont understand? Link to post Share on other sites More sharing options...
Nicoleica Posted November 28, 2009 Share #13 Posted November 28, 2009 Thank you.I do still not understand, sorry but that might be just me. Normally the light is measured through the lens also by M8 and M9, I presume. Normal light woundt do a pre-flash og pre-light, but it works? What is it I dont understand? Don't worry, this can be confusing. For non-flash exposures, the light is measured after being reflected off of the strip on the shutter blades onto the sensor in the camera body. This measurement is performed before the shutter is released on 'M' cameras. (There are some film cameras that continue to measure this reflected light off of the film during exposure, but that's another subject.) But for flash, TTL is a different animal. Most TTL-flash film cameras measure the flash reflected onto the sensor from the film during exposure. But this doesn't work with current digital sensors, and so they employ a pre-flash which is measured before the shutter is released in the same way as for non-flash exposures. The main flash is then determined and is fired once the shutter is open. Flashes that are not designed for digital use don't have the pre-flash capability, and so cannot be used for TTL flash with a digital camera. The 'Auto' mode on most flashes uses an external sensor to measure the flash, and so will work with film or digital. I hope this helps. Link to post Share on other sites More sharing options...
eritho Posted November 28, 2009 Share #14 Posted November 28, 2009 Thank you Nicole and all other. Now this is pretty clear. When/if the M9 ever arives I shall try out the auto way. I remember this to be pretty good from days long gone. Thanks again Erik Link to post Share on other sites More sharing options...
Guest mc_k Posted November 28, 2009 Share #15 Posted November 28, 2009 if you read all the threads here on the SF24, most people end up using it in Auto or Manual, so you may not be missing anything. Link to post Share on other sites More sharing options...
