Anything that is not a lens or a camera or an emulsion.
It is always so fun to bring to life a camera that you thought was dead junk. This Voigtländer Brillant from 1933 is probably the oldest camera I have. It is mainly a simple light-tight box with a lens. But it is still capable of taking some very nice photos in 6x6 format on 120 film.
My search for a 645 medium format camera ended with the Bronica ETRSi, mainly because of all the lovely photos taken with Zenzanon lenses that I saw on Instagram, but also because of its price. Now I am the happy owner of this camera and have already used it a lot. Time to start a field report!
Do you like the idea of a large-format view camera but don't want to jump into developing and handling large-format negatives? This was my idea when I bought a Horseman VH a year ago. This is a medium-format technical or view camera that has a good range of movements and allows you to get very close to large-format experience but stay within your 120 workflow.
One of the first film cameras I bought after starting again with film photography, and one of the few I have kept. This is an ongoing review and is updated as I use the camera.
