.The Bronica ETR-Si is not what is usually considered a pretty or elegant camera. I suspect in designing the ETR-Si, Bronica chose to go with function over form for nearly every aspect of the camera. That doesn't mean it's not good looking, but it's not the kind of camera you'd regularly see on a list of most sought after film cameras. Those kinds of lists are usually filled with names like Rolleiflex, Hasselblad, Leica, Nikon, etc. Because of this, as well as the fact that of all medium format cameras the 6x4.5 format seems to be the least popular, the Bronica ETR system is currently (IMO) one of the best values in medium format photography.
Efke 100 was an old school single layer silver rich black and white film from the 1950s made in Croatia by Fotokemika. Production ended in 2012 when the factory closed after an old coating machinery broke down and couldn’t be repaired. Fast forward five years, I was hanging with fellow members of the Classic Camera Revival Podcast, and Peter Lee told me there was an Ebay seller with bricks of Efke 100 in 35mm expired in 2015 for sale for about $75 Cdn, shipping included. How can I say no to that? I bought two bricks a few weeks apart.
