    Re: 24-70 or new 24-105?

    Lensrentals agree...
    I like to start articles by stating my expectations, because, like everyone, my expectations going in color my opinion after seeing the results. Given Canon's recent series of home-run lens upgrades, I expected the Canon EF 24-105mm f/4 IS II would be a superb lens. I was particularly expecting improvement at 105mm, which was the [...]

    (Plus I can see nothing wrong with my mk 1, even on a 5Dsr, that a 4x zoom range wouldn't cause.)

      Yes, agree. I'll be keeping my Mk 1 version.

        I also still love my 24-105 mkI its still my go to lens for team and individual player portrait shots.
        Like tigger if i do change this lens I will probably go for the 24-70 f2.8 next.

        but its only one stop faster.
        Though you think you are only getting one extra stop of light you actually get more as the range goes from f2.8-f3.2-f3.5-f4.
        So if your shooting at f4 and shutter is 1000'second f3.5 becomes 1250'sec f3.2 becomes 1600'sec f2.8 becomes 2000'sec,so becoming x3 faster hope this makes sense!starting to confuse myself now lol.

          Paul...you are confusing me.....1/2000 is only twice the speed of 1/1000 not three times.
          i.e in terms of the time the shutter is open is half the time....500 micro seconds instead of 1000 micro seconds....I think!

            Apart from the extra stop and the possibility of having the BG OOF I seem to recall that (depending on body, camera that is) the centre AF spot offers higher degree of accuracy with f2.8 lens.

            Probably not a major consideration the short focal lengths.

              Your probably correct Brian

                It might depend on your camera, but on a 5Dsr...
                24-70 f2.8 II is a Group A lens (the lower the letter the better the AF options available)
                24-70 f4 is Group C
                24-105 f4 is Group C
                So basically the f2.8-ness of the f2.8 lens is what makes the difference (Canon having AF points that work better with f2.8 or faster lenses).
                Basically you don't get the dual-cross AF points with type C (needs B or above, A has more of them)
