I still use a nearly 20 year old DSLR as my primary photography camera. It’s all personal stuff so the lower resolution and overall lower quality compared to modern cameras doesn’t bother me much. The battery isn’t doing so well after 20 years though, so I’m getting a couple new ones and a larger memory card for it. Hoping to buy a new camera soon and get at least 20 years out of that too, but I still plan to use my current one alongside any other camera as I really like the look of the images it produces.
It’s actually a 20D too! The new battery really brought it back to its prime, not having to constantly stress about it dying on me has been great
