Daniel Leung Posted March 29, 2009 Share #1 Posted March 29, 2009 Advertisement (gone after registration) I just got the new flash SF58 yesterday and did like 20 test shots at home. I love it, it is a lot more powerful that the SF48 ( I traded it in ) will do more test shts today DL Link to post Share on other sites More sharing options...

marknorton Posted March 29, 2009 Share #3 Posted March 29, 2009 ... and did like 20 test shots at home. What did you like about the 20 test shots at home? Link to post Share on other sites More sharing options...
Daniel Leung Posted March 29, 2009 Author Share #4 Posted March 29, 2009 What did you like about the 20 test shots at home? I was shooting a complete dark room about 40' long with the 28mm @ f4. the result is excellent. I have to take my son for a soccer game soon so I will have to post pictures later. H/e, compare with the SF48 that I previousely own, I can never get the sme situation bright enough DL Link to post Share on other sites More sharing options...
wattsy Posted March 29, 2009 Share #5 Posted March 29, 2009 A fairly powerful flash is a fairly powerful flash - I can't imagine there is anything particularly remarkable about the light that the new flash puts out. What I'd be interested to know is how accurate and usable is the GNC mode when used with the M8 (I assume that there isn't anything resembling a proper TTL mode). Is there a pre-flash and subsequent delay in this mode as there is when using the SF-24D? I'm interested in the new flash but only if it offers something (e.g. camera controlled output that doesn't involve any kind of pre-flash) which I don't already have with my Metz 54 (which I use in manual or auto modes). Incidentally, do you know if the new flash will talk to other Metz flashes (such as the 54) in a master-slave relationship? Link to post Share on other sites More sharing options...
marknorton Posted March 29, 2009 Share #6 Posted March 29, 2009 Ian, I think GNC is how it will work for the SF-58 - there's no ability to measure light reflected back off the sensor so it has to be done by using a pre-flash reflected off the shutter white stripe. So, you either use auto-mode and preset the aperture to what the flash says or else set the aperture you want, let the camera and flash work it out together and tolerate the pre-flash. One reason for the sluggishness of the SF-24D might be that after the pre-flash has sapped its power, it's not immediately ready for the main event where the SF-58 has power in abundance - it's certainly a powerful flash, more so than even my SB-900 workhorse.

Incidentally, do you know if the new flash will talk to other Metz flashes (such as the 54) in a master-slave relationship? May be this quotation out of the manual is an answer to your question: "TTL flash mode with metering pre-flash The TTL flash mode with metering pre-flash with the digital Leica M- models is a further development of the standard TTL flash mode of analog cameras. Immediately after the shutter button is pressed, and before the actual exposure, one or more almost invisible metering pre-flashes are executed by the flash unit. The reflected light of the metering pre-flash/es is evaluated by the camera. According to the evaluation, the subsequent flash exposure is adapted to the photographic situation by the camera. Notes: • Depending on the camera model, the metering pre-flashes precede the main flash by such a short interval that they cannot be practically distinguished from the main flash! • The metering pre-flashes do not contribute to the exposure."
