given these explanations,then an image taken with a 4/3rds 50/f2 and a FF 100/f4 should use the same shutter speed? After all, they are equivalents , aren't they?
Yes they will indeed use the same shutter speed if you have set both cams up for EQUIVALENT exposure thus:
mFT = ISO 100 and 1/100 sec @ 50mm and f2
35mm = ISO 200 and 1/100 sec @ 100mm and f4 ( if this cam also shoots at ISO 100 then it's shutter speed will be longer at 1/50 sec )
I hope that explains it?
