I set my M50 MK II to use aperture priority with auto ISO and it wants to give me the lowest ISO possible (great), but it's choosing shutter speeds of 1/60, 1/80... but even shutter speeds of 1/125 are giving me shaky photos.

Maybe I'm doing something wrong?

You might be. I have no problem getting sharp photos at 1/60 with the 22mm. Even 1/30 works most of the time for me.

Can you post a sample? It could be a defective lens, or some other issue. Shutter speeds of 1/125 should be more than fast enough.

EF-M 1/80 Shutter (focus was on rock under tree)

EF-M 1/125 Shutter (focus was on rock under tree)

Welcome to the forum and to the 'M' system!

+1 Welcome!  And thanks for posting the samples!

Something odd going on there.

+2

... the rock appears to be simply out of focus.

+3

Pixel peeping both frames, the sticks in the lower right corner and the leaves in the upper left corner are fairly sharp. This does not appear to be camera movement, it appears to be more of a focus issue.

+4

The M5ii and M6ii when in 'general' or zone focus mode will often focus on the closest thing in the focus zone.

+5

I've had situations where a few blades of grass or sticks or branches I didn't notice in the finder caused focus to be much closer than I thought.

+6

How was focus obtained? For something like this I would use spot or single point focus pointed at the rock

+7 Spot AF right on the rock.

perhaps or the tree slightly behind the rock to get some depth of field. Depth of field is going to be quite shallow at f2.5 anyway.

+8 Inadequate DOF is the other issue.

There's plenty of latitude there to stop down the aperture to say f/4 (or even further) without incurring a lot of noise.

Problem solved!
