What is the canon rf 35mm f 1 8 macro is stm good for?
The Canon RF 35mm f/1.8 Macro IS STM is a full-frame lens with image stabilisation and autofocus. On full frame it gives you a plain 35mm view, and its macro ability lets you get close to small subjects like flowers, insects and food details.
It also works well for environmental portraits that show where someone is, which is why I suggest a 35mm for that kind of work on my portraits page. On an APS-C body it frames like roughly 56mm, a more portrait-friendly view. If you're unsure which sensor size you have, the sensor sizes guide explains the difference.
It fits a long list of Canon RF bodies. For full frame, try the Canon EOS R6 Mark II or the Canon EOS R8. For APS-C, the Canon EOS R50 is a simple, affordable pairing.
