Get a flash diffuser. Will give better effect on your shots cos the light will be evenly distributed on the subject as well as the background. Lambency lightsphere is a good choice.
Other than that, get AA size rechargeables cos flash units are power hungry and using rechargeables are more cost effective over time.
I wouldn't say rechargable batteries are definitely the best source because I too tried using rechargables and they seem to be dying on me even on the very first time I used them. I somehow still trust my energizers. =D
hey guys, i got from a friend 4 pcs of 2000mAh Sony Ni-MH Batteries with the compact charger.
It's the CycleEngery type.
I've got hold of a 420EX, and will these batts be sufficient?
If i were to get those 2700mAH batteries in future, can i use the same charger to charge them, it says that it supports 2700mAH.
Hope i can save the $$ on the charger, if i have to replace the batt with 2700mAH ones.
