I am looking for a cheap optical viewfinder. No matter which brand, as long as it works with all kind of compact cameras (no electronics necessary).
I need the VFfor the FL of 28mm (DP1M/Ricoh GR) and more or less for 35-50mm (for Sigma DP2M with 45mm lens).
These could be Sigma viewfinders, Ricoh viewfinders, Voigtlaender viewfinders... you name it..
Shipping in US and Europe possible. I pay with PayPal.
