        Not too wide to be f/2! You can get very shallow with up-close objects. This removes the need for faster prime wides.

        You can stop down to 2.8 and likely ensure optical beauty, even if wide-open is slightly unsharp (as wide-open often is).

        In many cases any bit of light helps.

    2-2.8 looks delicious!
    By the way, this lens seems to be internal focusing :D

      And also that the high disperson lens in this patent corrects for chromatic aberrations present in the old lens.

      What else would it be?!
      You have to hold an additional element by hand in front of the lens!?

      j/k! :-)

    I agree I’d prefer to see a f2-2.8 in the 24-70 range. But this would make for a great low light focusing journalist lens.
