  • Your comment was controversial with the pentax K-7 released, but is definitely flat out wrong now that Pentax has the k-5 which should run circles around any equivalent aps-c Canon on the market right now. Of course ruining the lens probably made this point moot anyways for using a Pentax body...

  • @gtownb The lens is by no means ruined, putting it back into original state is a matter of 10 minutes.

  • @bildensiemal

    Sorry, I must have misunderstood. Did you not cut off the aperture lever? What can a layperson do in 10 minutes to remedy that?

  • @gtownb

    part 1:

    On most Pentax lenses I know, the aperture lever cannot be easily removed, because the aperture ring also acts on it. Removing it not only takes away the automatic aperture function but also means the aperture can no longer be set manually. I initially assumed this was also the case with the 1,8/31, so I cut the lever off (it is an inexpensive small piece of metal, no big deal anyway).

  • @gtownb

    part 2:

    I now know this was an error. The lever can be easily removed (without impairing the manual aperture function) and can be put back into place.

  • Is the aperture lever removal a permanent modification?

  • @SelrahCharleS

    No - the aperture lever can be removed as a whole. Should Pentax ever market a full frame camera to match this lens, I will happily put it back in.

  • Great video, I have the lens on a K5 but I'm thinking of getting the 5D instead. Do you have any photos taken with the combo?

  • What about the IQ of that gorgeous Pentax lim?

  • @baov

    No - it does not vignette. It looks as if it would - but it doesn't.

  • The mount is crooked, that hood is gonna be vignetting, especially if this lens is wide angle.
