user603: I'm looking for an external DSLR monitor that is not bigger than around 3 inches. For example, 4 or 5 inches is too big. I need something small and not bulky, for skateboarding videography.

user2994: Zacuto makes an EVF monitor that is 3.2 inches, and I can say from experience this is the real deal...Has built in sharpening monitoring to help with focus support, and has a detachable eyepiece...also look into their camera rigs fro your skateboarding videos, they could be really helpful for you.
