Mantice Posted February 9, 2009 Share #1 Posted February 9, 2009 Advertisement (gone after registration) Hello: I search the forum and found many pieces of information regarding R6.2 TTL flash. I found what I need and what flash to get (SCA 351 + extension + Metz 36...) However I do have several newbie questions... (1) I'm trying to do handhold macro on 100/2.8. Will 1/125 sync speed be too slow? (2) What does TTL do? I never do flash in my life and I only read articles about auto flash (which I don't understand most of them). Does it means that when I enable TTL on Metz flash, set X sync speed, any aperture I want and just fire away? (assume the combination does not excess maximum output from flash) Any help?

Michiel Fokkema Posted February 10, 2009 Share #2 Posted February 10, 2009 Hi, I think sync flash on the R6.2 is 1/100th. Just put it on X. Yes, if you set your flash on TTL, the camera will determine the flash output during the flash itself. Just fire away. No need to set aperture or iso on the flash. The camera takes care of it. BTW: you can use Nikon extension cords. Nikon has the flash contacts in the same place as Leica. Cheers, Michiel Fokkema Link to post Share on other sites More sharing options...
Mantice Posted February 10, 2009 Author Share #3 Posted February 10, 2009 Thanks Michiel: Will the TTL be accurate even in macro distance? Also do you think 1/100 is enough to freeze the motion in macro handhold? Link to post Share on other sites More sharing options...
masjah Posted February 10, 2009 Share #4 Posted February 10, 2009 Mantice With really close-up work using the flashgun on the camera hot-shoe is not entirely satisfactory, as the beam will not be aimed directly at the subject. You could try using an extension cable, which would permit remote mounting. As michael says, Nikon cords have the same pin-outs (though that does NOT mean that the pins on Nikon guns play the same role as the Metz with SCA 351!!!). I would counsel against hand-holding if at all possible. It's not just a question of avoiding camera shake, but also the fact that the focus is so critical and the depth of field so small at these distances. Hope this helps.

Mantice Posted February 10, 2009 Author Share #5 Posted February 10, 2009 Hello John: You're right, I actually feel the same way~! But when shooting insects in the woods there's really not much I can do with tripod - set it up, its gone - or in impossible place to set-up tripod. I tried Wimberley M-4 brackets already; its still the best flash bracket I ever use but at 14.7 oz its going to kill my neck sooner or later~ But I'll look into the nikon cord - thanks for the recommandation!

Michiel Fokkema Posted February 10, 2009 Share #6 Posted February 10, 2009 Thanks Michiel: Will the TTL be accurate even in macro distance? Also do you think 1/100 is enough to freeze the motion in macro handhold? Not sure. I've never done it but in principle I don't see why not. If you close down the aperture enough to underexpose regarding to the ambient light the flash will freeze any motion. I bought a cheap extension cord on Ebay. Works fine.

graeme_clarke Posted February 10, 2009 Share #7 Posted February 10, 2009 Advertisement (gone after registration) For subjects such as insects a beanbag is a good alternative to a tripod. I made mine with 500g of small plastic beads. Dried rice or lentils will do the same job - its really a small cushion that the camera sits in. See if you can acquire a 90 degree viewfinder (but they fit into the hot shoe). Flash at such short distances is best done with either a ring flash or the gun off camera held to one side with a long cord. But depth of field is measured in mm or less - so hand holding is not easy as you should use a small aperture - typically f16 or f22 - hence shutter speeds are very slow if you don't use flash.

rick_dykstra Posted February 17, 2009 Share #8 Posted February 17, 2009 Mantice, the Nikon cord you can use is an SC-17. It sells on ebay for around $30-40 USD. TTL control with the R6.2 is rather agricultural compared to the R8 or R9. You might find you get over exposed shots with macro work. Throttle the flash back as necessary and let the TTL do the final adjustment and it could work well enough for your purposes. Another idea would be to use an expired film to do some flash power tests. The reflection surface off the film will enable the TTL meter to work properly as you do the tests. - find a subject that is composed of mid tone colours, similar to the shots you will take in the field. - dial the flash right down and gradually bring it up with each test shot until you have sufficient flash light for the TTL meter to register correct exposure. This should put you in the ball park for a particular combination of aperture, distance and subject. Note these settings and then shoot some real film. Learn and adjust. :-) Enjoy using the R6.2.

Mantice Posted February 22, 2009 Author Share #9 Posted February 22, 2009 graeme_clarke: Indeed, off-shore cord is the answer (ring-light is abit flat), I got lucky to find 14$ Metz offshore cord of KEH! Beanbag sound like a great idea too but not sure about 90 degree right angle - because I don't mind getting dirty and lay on the ground so maybe not justify the cost (cheap these day though). Rick: I got some test shoot today and it all looks good, but contract was alittle low in some picture (slight over-expose), I'll do more testing as you suggest. Big Quesetion: How does TTL on R6.2 work? I read alot of literature saying TTL flash uses internal light sensor to adjust the flash, but what information got transferred and what not? How does it control the time and output? Link to post Share on other sites More sharing options...
