Auto-zoom in problem. CAmera issue

Greetings. DEar developers, please, watch this video. On this video I push only 2 buttons- up and down. When I push DOWN, camera makes auto zoom in. When I push UP- zoom out. ANd now just imagine, that players in dungeon always move UP and DOWN and always have to use mouse's wheele to ZOOM OUT camera. It is very uncomfortable to do so. Please, dear developers, fix this auto zoom IN problem

I want to say, that Im using Legasy type movement setting, because Standart mode is very bad for me. So, I think, that this zoom in issue is only in Legasy mode. Please, fix this problem. Thank you
