Many photographers, myself included, often tout the ability of mirrorless cameras to utilize old film era lenses to save money and try new focal lengths without breaking the bank. But when does this make sense, and when does it start to be a bad decision?
Well, the whole benefit to it is utilizing lenses you may already own, thereby saving you money. Where some people go wrong is by going out and finding film era glass to buy specifically for their mirrorless camera. Ok, let me back up, because buying an old lens on its own isn’t a bad idea, but there is a point where the cost of that old manual glass starts to come really close to native glass you can get for your camera and at that point, it makes much more sense to just save a little longer and get the native glass for your camera.
