Not sure if this counts but my original Canon 5D is still my favorite camera. It came out in 2005 which is almost 20 years ago. I've tried many other cameras but always come back to my 5D. I don't think it's nostalgia though, it just works really well, I love using it and I love the results.
I still take photos on a 5D Mark II because I don’t see a big reason to upgrade. The photos look great and I’m familiar with the layout. I know there are plenty of improvements to be had in newer and better models, but I’ve managed to work around its flaws and still take good photos. It being old helps me feel comfortable taking riskier shots, too.
