So I have a Canon m200 (ef-m) and I bought an Ef-s / Ef-m mount adapter. Nothing special, just a piece of plastic and electronics from Meike. However, I recently came across a YT reels making a review of a extension tubes: a device that one could install between the lens and the body in order to get a smaller minimum focus distance. (The guy even stacked several of them, largely minimizing the focusing distance and increasing the focal length). That device look very similar to a mount converter -the only difference being that the input and output mount is the same-. So, I have the following questions:โ Do mount converters affect focal length? (I have a ef-s 55-250mm lens and even if it's just 10mm longer than my kit lens, I feel like it is much more. Maybe I just need to get use to it, but I could swear that it is too long.)
โ Do mount converters minimize focus distance? Since they enlarge the distance between the sensor and the lens, I thought it would maximize the focus distance.
Thanks a lot for your help :D
