The most fundamental thing that sets Apple apart from Android. Apple’s seamless experience is because they do their own hardware and OS…plus they have their strict app devs guidelines. Android being open is sounds great but that Android as an OS has been fractured from the start because everyone and their moms wanted to put their own spin on the OS for THEIR hardware. I want tools and appliances to work efficiently and as intended.
I would shoot with your kit lens and keep the 35mm handy. First time shooting at a school to document events isn’t about how “artful” the photos look…nor “wow, the bokeh” You will want to have the flexibility even for the short reach of the 55mm. Ideally you’ll want something along the lines of 24-105 or 24-70 (I’m a Canon shooter)
