Is there any software for focus tuning for Pentax K1?

Note that Nikon DSLR's (or Sony, and also Canon I think) don't even include the option to do pixel mapping in-camera to clean up dead pixels, something even entry-level Pentaxes have had on the menu for ages.
With some Nikon if you clean the sensor twice in succession they will map out dead pixels

You can fine tune for individual lenses. The camera can store the settings for 20 different lenses of the user.
What happens when lens 21 is calibrated?
By user do you mean user setting U1-U5 or an individual camera?

No idea on the first question, i don't own 21 AF lenses ! Perhaps it overwrites one of the previous settings.

The 20 A/F Fine adjustment settings are per camera , not specifically associated with the USER modes. There is in addition a global A/F Fine Adjustment setting that you can use which will be applied if you attach a lens that has not been calibrated individually.

Hello

I read about an Issue with this lens in the "Lens Database"; Sigma 35mm F1.4 DG HSM (Art) Lens Reviews - Sigma Lenses - Pentax Lens Review Database

Nothing is wrote about what the exactly problem was?


Has someone more details?

The mount slightly scratches the body of the K1. The deeper bezel fixes the problem.

Guess I have been super lucky with this lens then, I love it and not had an issue with the focus. This photo was taken this weekend and heavily cropped so focus must be ok if I can have a selection of flowers and still get the bee pretty sharp.
