Ok had this mood to test my flashes. so far did just 3 SB900 SB700 yn560III-will do the others as well.
I put the flash on a yn622n transceiver. put my sekonic l-718 flash meter on a light stand using a manfrotto clamp with stud. I measured 1m and placed the flash head exactly 1m from the light meters dome head.
SB900/ used it at the 35mm zoom head setting. manual power mode. aperture was the highest it could go which was f/64
Sb700 doesnt have the aperture setting selector. just power amount and zoom
560III is the same as SB700.
I used a 622n transceiver to fire the flash. waited 30 seconds in between each pop. energizer 2300mah NIMH batts were used. quite new. opened 3 new packs of them and they were recharged overnight. each flash got a new set. and were tested from the first pop. meaning, I didnt put the new batts in and fired off a shot. I put them in, made sure the channel on transceivers was good, set it up and shot as to give the batts as much power as possible.
light meter is a sekonic l-178 and was set at iso 100 1/125 shutter and only measured for flash and not flash and ambient mixed.
results. this test was just for pure max power at 1m at 35mm zoomed head
SB900
-1st pop--- f/16 + 7/10 stop (maybe I was off on distance and remeasured)
-2nd pop--- f/16 + 9/10 stop
-3rd pop--- f/16 + 9/10 stop
Sb700 and this kinda surprised me
-1st pop--- f/16 + 9/10 stop
-2nd pop--- f/16 + 9/10 stop
-3rd pop--- f/22
yongnuo 560III
-1st pop--- f/22 + 2/10 stop
-2nd pop--- f/22 + 3/10 stop
-3rd pop--- f/22 + 3/10 stop
I was surprised by the SB700 matching the SB900 and I want to recheck this. could it be because the SB900 is an old model. in terms of age and use compared to my more newer and less abused SB700?
the 560III also surprised me because although specs say its as strong as the SB900/910, I thought it was more hype than truth. but here it shines. its very strong and also VERY fast to recycle. the SB700 is 2 years old, the SB900 is 3 years old and the 560III is less than a year old.
any questions, feel free to ask. maybe im missing something
I will test the metz 58 AF2 the SB28 I have, the yongnuo 568 flagship when it comes back and the SB800 (two I have). I will also ask my best bud nicely to let me test his new SB910 and see how that is as well.
cheers guys
