I have been in to photography for many years. Over those years I have acquired many cameras of many shapes, sizes, formats and age, though most are 35mm SLRs. I bought almost all to take pictures with, not to collect. Though there are a few I just had to have, working or not. Recently I found a site where a guy had taken pictures with 52 cameras in 52 weeks and posted the results. https://www.soperfectimages.co.uk/52-cameras-52-weeks/about-the-project/
It gave me the idea to take pictures each week with one of my cameras, post them and say a few things about the camera and see just how many weeks this could go. My plan is to go from oldest to newest. What with the time to get film processed these days, post may be clumped as prints come in.
