Back to E-M1 Mk.II Lens Fest, Part 1

F = 14 mm

Full frame, reduced, at F/8

F/3.5

F/4.0

F/5.6

F/8.0

F/11

Obviously, this is no match for any of the μFT premium zooms, and it especially shows at the wide end. The image is fuzzy, center and off; surprisingly, it looks best at F/4, almost wide open (or even F/3.5).

Light fall-off (or vignetting) is quite intrusive, but disappears at F/5.6. It can be easily fixed in-camera by activating the proper feature (which I had disabled for sample shooting).

F = 25 mm

Full frame, reduced, at F/8

F/4.7

F/5.6

F/8.0

F/11

Much better than at the wide end; I would say respectable, center and corners. Best at F/8, which is also the aperture at which vignetting goes away.

F = 42 mm

Full frame, reduced, at F/8

F/5.6

F/8.0

F/11

At the long end the lens is quite unsharp when wide open; stopping down to F/8 clearly helps and, unexpectedly, to F/11 — even more. Still fuzzy but less so.

This just means that we lose less resolution due to diffraction than we gain due to using just the central part of the lens.

Vignetting is not something expected at the long end of a zoom, but it is here, going away at F/8. Just turn on the Shading Compensation option and forget about it.
