I personally use dye i3's with no problems.not Dye I3's in my opinion.. used them jus recently and cudnt see much of the viewfinder at all.. anythin with a flat front profile (like the profiler) would be good i imagine.. lets you get close to the viewfinder as you naturally would..
i found a lot of my shots werent composed as well as i thought they were
but i still got some crackin ones
