What is the canon rf s 14 30mm f 4 6 3 is stm pz good for?
The Canon RF-S 14-30mm f/4-6.3 IS STM PZ is a power-zoom kit lens built for vlogging. It's made for APS-C cameras, where it frames roughly like 22-48mm on full frame, so it covers wide scenes through to a comfortable standard view. The power zoom and image stabilisation make it easy to reframe yourself or move through a scene without fiddling with a zoom ring.
The f/4-6.3 maximum aperture is modest, so it's best in daylight or well-lit spaces, and you won't get much background blur. If you're after that, look elsewhere.
For most people, the Canon EOS R50 V is the natural partner, since it's the body it's sold with. The Canon EOS R10 and Canon EOS R7 are more capable APS-C options if you want more control. You can also check the focal length converter to compare its framing with lenses you already own.
