I never used the Sony came

I never used the Sony cameras for filming wedding videobut I’ve used the EX3 and EX1 for other events. Both cameraperformedreasonably well in low light. But they are both ouf your budget.

I have used the JVC GY series for weddings. These camera a great. The best part isprofessional Fujinonlens. It’s probably the best lens I’ve used.

I use DSLRs for weddings as they are cheaper and produce great image quality event in low light. Why don’t you want to use DSLR? Also for the money you could get two DSLRs. Two cameras is essential to film weddings.
