I changed from 2 inon s2000 to 2 retro pro 2 years ago...
Euhhhh it's change more or less all
The pictures quality make a jump.
I'm really happy with my retra... but today the price is much more higher as to years ago. For sure If one break I probably don't buy retra again... but buy something btter/stronger as the s2000.
or not sure.... I've now snoot for retra protection for retra etc etc..... but for the moment my 2 retra are working well and I hope it will be the case for the next years ( 2 , 3 4 or more ??? )
Next trip end of the week, 3 weeks Philippines with a lot of pictures... The flash will probably shoot 4k or more times
