So I wanted to get a general feel of what sort of batteries people use, What brand and whether they are rechargeable.
I was using Energiser because i got about 16 when i first brought my Speedlite, and now i just brought 40 Duracell because i got them at around the same price, about 30ยข a batterie. I was going to a 21st and only had my last 4 batteries so i popped into a Service station and brought a 4 pack, These were a brand i had never heard of before and 4 batteries were as light as 2 of the Duracells. these Batteries lasted 200 shots, while the energiser ones last about 300-400.
I am still waiting to see how well Duracell batteries perform and will keep you all posted, I'm a bit iffy about using rechargeable.
And yes the flash is on the same settings and same power for all the shots.
