Should my first camera be full frame or aps c?
Here is what the site says about that.
From Your first camera: Your first camera: A good phone is a very good camera in daylight. It does a lot of clever processing for you, and it's always in your pocket. So the honest first question is what a real camera would give you that your phone doesn't.
From Sony a6500: Sony a6500: A mirrorless camera by Sony with a 24.2-megapixel APS-C sensor, announced in 2016. The first Sony APS-C body with in-body stabilisation.
