Nikon sb800 + extra battery pack Vs, Nikon sb900 flash recycle times

[chai12834]

great videos dom...

wondering if you can make one solely about how to set up your sb 900 and use it wirelessly with my nikon d90. Thanks!

[eakiboz]

you forgot that the sb900 is stronger than the sb800, at full power the sb900 is producing alot more flash than the sb800 so it will take longer ...

[dombower]

@eakiboz a lot more? really, do you know how much more?

[lg123xyz]

@eakiboz would you happen to know the output for the SB-800 and SB-900 and difference in power?

[eakiboz]

@lg123xyz i`ll take that back, i think they r the same power, i got mixed up with the zoom. the sb900 goes to 200mm and the 800 to 105mm

[lg123xyz]

@eakiboz ok thanks a lot appreciate it!

@lg123xyz yep it is on the blog and the new channel

PART TWO-: mAh = capacity, thats how long it will last. Volts = power Thats its "grunt".

You need grunt for fast recycling and the batteries dont work as hard so they and the circuitry dont get hot.

[dombower]

@pedalman check my other videos and you see the rechargable ones recycling the flash a lot faster.

[pedalman]

PART ONE -: 1.2v rechargeable batteries do not have enough voltage in HEAVY shooting conditions to recycle quickly 1.5v are needed.

The batteries have to work harder and they get hot, the internal circuits also get hot and on flashguns with thermal cut outs the flash stops working until the temp drops (the temp is not down to the temp of the flash head, its mostly internal"wiring"temp)

Even large capacity rechargeables 2850mAh wont cut it, they just last longer at their low 1.2v.

Cont above

Using rechargeable batteries can probably affect the recycle time considering that they only produces 1.2 volts and Non-rechargeable batteries produce 1.5 volts.

I do not have the 900, but in my SB-400 User Manual, NIKON states the FASTEST recharge time with NiMh batteries. Hmmmmmm.........

[timmis1971]

Try swaping the position of the units etc, or try them on the same camera at a fixed position and time the recycling with a stop watch to get a more varied & acurate test result.

[PapaJoFilms]

Yes the SB800 seems to have a faster re-cycle time but the SB900 is a more powerful flashgun and is doing more work.

Try the same experiment but have both guns set to give the SAME amount of light and then see which one is faster.

[dombower]

only faster with the extra battery. check the other video. true it is a bit mroe powerful, again shown in an other video, trying to figure out the same amount of light is impossible. best just have them on full power.

[dtoosh]

OOOOOOOH! Best part of the whole video!

[Bader88]

LoL Very interesting

[priiti]

Please help.

Is this a problem when I user rechargeable batteries with my SB- 900? For example 2700 mAh batteries.

Problem is that I find i cheaper to use rechargeable batteries, but is it bad and is there a problem?

[dombower]

from my experience there is no problem.

[pedalman]

You have probably already seen it but take a look at Lilkiwiguy parts 1-4 "SB 900 overheating problems solved"

Seems its the 1.2v rechargables working to hard, they over heat the circuits in the flash overheat and thermal cut out kicks in. Its nothing to do with the flash head getting hot it the internal circuitry.

Solution, use 1.5v duracell or a quantum pack when heavy shooting ....200 shots hr . they dont have to work as hard so dont get as hot.

[dombower]

thats a good point but i watched that and i did a video showing that my rechargables recycled the flash much quicker than the single use ones like in his video. kind of disproving the idea that it is about voltage and not mAH performance

[shadowblack1987]

My SB-900 recharges a LOT quicker than my SB-800. I use eneloop bats.

[eatmypixels]

Just a small point Dom - The SB900 has a problem when using rechargeable batteries, causing it to become too hot and recycle a lot slower, possibly doing damage to it. I'm not sure if this SB800's too though.

I'm not moaning at you, just wouldn't want to see 2 very nice flashes (neither of which I can afford - student, woo) get damaged due to something small and mostly unknown about like that :)

[dombower]

I have heard this before but i have been using this flash a lot and had no problems at all. I think it may be some spin by canon to make this flash sound like it has a problem.....

the temprature gage on the sb900 has never gone up with all my flashing.

Please anyone out there actually have this problem please tell and explain why youthink it happened.

[solidliqs]

That lie was propagated by some blowhard who knows nothing about electronics and came up with the theory.  His theory is completely invalid. He didn't even know you could have more than 1000mAh in a rechargeable AA battery.

[turlesRfun]

lol nice thanks now I know which one to go w/ :P

[imarkphippen]

what was the music at the start?
