Based on my zoom lens, the Yashica Tele-Wide finder matches 18mm and 35mm on a 4/3 camera in 3:2 mode. So, the Sigma 19mm is a great fit for it. All I have left is a vented lens hood for better peripheral visibility. Shooting even with a basic optical viewfinder is so much better than using the LCD, and sometimes better than a good EVF.
