If this is going to be your first 4x5, congrats! We're honored you're making the move with one of our cameras. Each camera comes with a Pinhole Lensboard so you can start shooting quicker. But if you want another lens, you will need to purchase one and a lensboard to mount it. We recommend you (carefully) search for something on Ebay or another resale source. The lensboard needs to be a linhof style board. You will also need filmholders, a light meter, and a tripod. There are quite a few options for light meters including apps for your phone, simply carrying a DSLR for metering, or a dedicated meter - Sekonic is a pretty common brand. Optionally, a dark cloth is helpful when shooting, but there are plenty of things that you can use in place of one. Us and our friends have used everything from a black t-shirt to a rain coat in a pinch. Feel free to message us if you need some help!
