Rangefinder viewfinders for dslr and mirrorless users

[@calinguga]

bought mine for my rangefinder, but i use it the same way, carrying it around looking for shots, or ballpark framing before swapping the fixed lenses on my slr.

Will both external viewfinder fit Leica iiig?

[@pendzelnawungiel]

Yes they will. They're standard. I used helios one and now only KMZ 35mm on my iiic

[@solb101]

How easy or difficult is it to frame with the hellos finder without adjustment for parallax error and magnification?

[@thearchitecturalphotograph2973]

I use it more like a director’s viewfinder. Or rather, I did. I now have a Linhof.
