Hi Eric,Hi OlyFlyer,
So with the FL-50, during poor/zero lighting focusing... there isn't that burst of flash akin to the built-in flash?
Cos that "burst" irritates the hell out of my subjects... ;p
Will we see a so-called red light/pattern???
Thanks,
Eric
Oly..I added 2 AA of 2000mha in parallel to get the 4000mha. Me poor man cannot afford anything higher than 2000mha yet. So Do you think the FL36 would charge faster with that setup? It sure beat paying double the $$$ for a FL50.
Yes, I think if you have four batteries, two pairs connected in series connected in parallell than you should get a faster charge. That way you have 2.4 V and 4000mAh with your batteries.Oly..I added 2 AA of 2000mha in parallel to get the 4000mha. Me poor man cannot afford anything higher than 2000mha yet.

That is only partially true. If the FL-36 has current limiting circuit and not takes all the juice it can when charging. In my experience same voltage but higher capacity ALWAYS with every flash I ever owned gave faster recharge because my flashes took all the energy they could. A higher capacity battery can deliver more power during the same time period without demage. If that would not be true you would get faster recharge with non-rechargable alkaline batteries giving 1.5V / battery than rechargable giving 1.2V. The recharge order is even stated in the manual. Of course, best combination is higher voltage and high capacity.I don't think it works that way. If you 'tap out' the power terminals from the battery bay to use a DIY battery pack, adding an extra pair of AAs doubling the battery capacity would make the flash last longer (possibly 2x) on that set of 2x2 AAs (= 4000mAh 2.4V) but refresh time will still be the same.
Yes, be warned! Pushing the envelope is risky. But there is another risk involved here. You must be aware of only using EQUALLY charged batteries all the time. If not than there is a risk for current flowing in the wrong direction that can, at best, result in demaging your batteries but at worst it can explode in your face. So, never mix batteries.**THEORY ALERT** **CAVEAT EMPTOR** Adding another pair (3x2 AAs = 4000mAh 3.6V) to raise the voltage to 3.6V (based on 1.2V NiMH cells) should charge the flash's capacitor quicker leading to a shorter refresh time. It may also very likely send your FL-36 to an early grave if the voltage is too high for the circuits or even if it does survive the boosted voltage, prolonged use will probably kill it sooner.

Yes, if you already use high capacity batteries there is a limit. But why not try 4 alkaline 800-1000mAh batteries giving 6V and compare with 4 NiMH 2500mAh giving 4.8V? You'll notice the difference. It is also stated in the FL-50's manual. Slowest recharge is with alkaline batteries. Actually what we say is the same, higher voltage makes bigger difference. Only I add that you still need current too, which I am sure you are aware of too. If that would not be the case two CR2032 batteries would be the best, giving 6V in series, very low weight. OK, they are not very cheap but that's another question. Unfortunately with their 220mAh they would not be able to charge the flash at all.I have tried connecting a set of high current drain Sanyo sub-C "SCR" cells to my FL-50 and it doesn't speed up recycling time. Boosting the voltage to 6.0V (from 4.8V) by using 5 cells did speed up recycling noticeably but the FL-50 got really warm after 40-50 bursts.
...
Alkaline dry cell: 6sec 150 flashes (note: this is 4x1.5V = 6V)
CRV3: 5sec 220 flashes (note: this is 2x3V = 6V)
NiMh (1900mAh): 4sec 170 flashes (Note: this is 4x1.2V = 4.8V)
This is also my experience. BUT, by adding a fifth 1.2V NiMh would make it even faster.
Again, I have no idea about the FL-36 and its limits and electronic circuitry. The above is valid for FL-50 only, discussions about the FL-36 are just guessings from my side.
I don't think so. When the FL-50 was originally made the highest capacity was about 2000mAh, so they only specified with that one. I know for sure my FL-50 charges in less than 4 seconds from a fully discharged state to a fully charged. Anyway, I am on my way to get a set of 2700mAh batteries and it will be interesting to see if that will improve even more. Otherwise I agree with Oly, equipment must be protected from persons like you and me and other DIY people. I don't know where the limit is but there is definitely a limit. I will definitely survey the four contacts for external power on FL-50. So far I only know that there is 5V on the longer ones and one of the terminals are directly connected to the built in battery - (minus) terminal. The question is, would it be a good idea to connect external batteries to this terminal? Would it improve anything or would the FL-50 start to give smoke signals????????? :dunno:I believe the voltage and current from the AA source is being intentionally limited to prevent effective use of DIY booster packs and to protect the flash unit from the user :bsmilie: Also serves to sell more $$$ SHV packs and cover Olympus from the black suits should we get ultra high current dynamite cells in the near future (1.2V 10Ah AAs anyone? :sweat: )
Reading the Metz brochure which says that
Metz 54 doesn't support Olympus; only 44 with SCA3202 adapter does.
Was it really 54 that was tried?
How is the performance and how much for that metz?
