Hi all,

i want only inform on next issue. I find some strange in higher shutter. When i have set higher shutter like 1/125 and more. I see this lines only in indoor lighting. Outoor i dont see this lines. This lines going slowly from up to down.

I try 3 another EX1s all have this issue. If is this issue. FW is 1.03 .


For me isnt this big issue i dont use higher shutter indoor but for someone maybe is.

This is due to your lighting source.

Yes, you are see the CMOS rolling shutter.

What kind of lighting fixtures were these?

Zenes, try a tungsten light, the lines should dissapear.

Fluro or HMI lights with electronic (aka HF) ballasts will eliminate the problem.
Low wattage incandescents might still give you problems.
