If you need the small size keep the 40.

The conventional wisdom back in the days of film was that if the FL difference was not by a factor of at least 20%, it was not worth owning a lens on the basis of FL alone. So other factors, like relative size/weight might make two similar FL lenses worth owning, as you might prefer size over other advantages at different times. Some of the other criteria worth pondering

  • f/2 vs. f/2.8
  • how much you prefer to use moderate wide 35mm FL over a more 'normal' FL (if FF)
  • how much you prefer to use 'normal' 35mm FL over a short tele FL (if used on APS-C)
  • if shooting video, STM better due to lower noise while focusing
  • IS capable lens vs. not

  • This is only true for some STM lenses. Frankly the 40 STM & 50 STM are noisy. No quieter than the sound of USM. You can plainly hear them. The 18-55 STM however is dead silent and you cannot hear it.

    Not all STM are the same for silence with respect to audio recording during video.

    Very best,

    I would even say that my 50mm STM, at least, is actually noisier than the USM motor on my 35mm f/2 IS.. It's a surprisingly noisy and annoying whining kind of sound. And it's definitely not as usable for video as other STM lenses. The quietest lens I own is the Sigma 18-35mm f/1.8. It's almost as silent as the most quiet STM lenses.

    Agree, the 40 STM & 50 STM so far have been the noisiest of the STM's I've used. Even the 24 F2.8 STM is noisy. Those pancake versions are just not the same as the ones in the zooms.

    Very best,

    My 35 f/2 IS produces higher contrast and better colors than my 40 stm. I sold the 40.

    TWO THINGS:

    1. The 35mm f/2 IS is a great video lens on my 6D Mark ii. I don't record with the in camera mike so focusing sound is no problem. The IS of the lens combined with the in camera IS (for video) is really nice.

    2. On a 1.6x crop camera, the 35mm, at 56mm equivalent is (IMO) a better and more natural focal length than the 64mm equivalent of the 40mm. I think that a 35mm f/2.8 STM lens might have sold better:rolleyes:.

    3. (I lied when I said two things:-() the extra stop of the f/2 lens can often save the day in shooting under low light conditions. The 6D Mark ii with 35mm f/2.0 IS lens is my favorite low light combination...

    BTW: I own both lenses and seldom use the 40mm for either video or stills since I got the 35mm f/2.0 IS.
