I am a beginner photographer, currently using a Cannon 200d with the kit lens (EF-S 18-55mm f/3.5-5.6 IS STM), after trying for a long time to get shots of my wife with a blurry background with no success I have recently found out by playing around I can achieve a blurry background by zooming the lens all the way to 55mm and of course putting the blur setting to the max (can remember what that is called).
The problem with this obviously is zooming right in means I have to stand quite far away from the target and I can not quite get what I am after, also more blur would be good. I understand I might need to upgrade the lens and after a bit of research the Cannon EF 50/1.8 STM look to be a great option and is also quite cheap.
I was assuming (but want to check) that this lens will provide more of a blur as it has a lower aperture, but will it be a set amount of blur for every shot with that lens as the aperture is fixed and not adjustable like the kit lens?
Also, being a 50mm lens, will it always be zoomed in like the kit lens when I change it to 55mm?
These are probably really silly questions to people more experienced but we all have to learn somehow right?
