Constant f/4 aperture from 24 to 105mm. The EF 24-105mm f/4L IS USM offers the highest possible optical quality with no change in aperture over the full focal range of the lens. This allows photographers to set exposure at the widest aperture and zoom all the way through to 105mm without having to vary the shutter speed.
I need to buy a general purpose zoom lens and i need to decide between this two lenses, Canon 24-70mm f/2.8 L USM II or Canon EF 24–105mm f/4L IS II. Taking in consideration that i was planing to buy Canon 35mm 1.4 ii, and now i think i might replace it with the Canon 24-70mm f/2.8 L USM II.

The Canon 24-105mm f/3.5-5.6 IS STM is an optically superb lens in a lightweight, light-duty plastic barrel. So long as you don't plan on shooting in pouring rain for hours or otherwise physically abusing it, this 24-105mm is an extraordinarily good and handy lens for all Canon EOS cameras of every format, especially full-frame.
