Canon rf 24 50mm f 4 5 6 3 is stm vs canon 28 70mm f 2 8?

The 24-50mm f/4.5-6.3 is the small, light kit zoom. It's a good everyday lens, but its aperture gets darker as you zoom in. The Canon RF 28-70mm f/2.8 IS STM holds f/2.8 across its range, which helps in dim rooms and gives more background blur. It also reaches further, to 70mm on full frame against the 24-50's 50mm, so it's the better pick if you shoot people or want more reach.

On full frame, the 24-50 goes wider at 24mm. The aperture guide explains why a constant f/2.8 matters.

If you want the lightest kit and you mostly shoot in good light, get the 24-50. If you shoot indoors or want the brighter lens, the 28-70 is the one I'd save for. I haven't covered the 28-70's full camera list or stabilisation here, so check its page before you buy.
