Panasonic LUMIX G Lens, 25mm, F1.7 ASPH, Mirrorless Micro Four Thirds, H-H025K (USA Black)

Product Information

However, during the course of my testing I came across a slight catch; the lens’s plane of sharp focus shifts forwards fractionally on stopping down, which is a symptom of residual spherical aberration. You can purchase un-coated replacement optics for you lens, which will give your images a more vintage look.

The FF photo will look darker at default settings, but when you lift it two stops in post it will be identical to the m43 photo, including noise levels and DOF. Autofocus is, in the grand scheme of things, very accurate, regardless of whereabouts in the frame the focus area is positioned. Panasonic has adopted its usual approach of correcting distortion in software, and in practical use you’ll have to go out of your way to get anything other than perfectly square images.Although it does suffer from some chromatic aberration issues, the good news is that these are of the kind you can most-easily correct in the digital darkroom.

Panasonic takes pride in the smoothness/polishing of its aspherical surfaces/molds, and it shows here. At the 25mm end the story is similar at the center of the frame, with slightly sharper results wide open than stopped down to F6.

Trying to think back at this, it's easy I think to grip it too hard, so like a stuck filter if we deform the ring it won't turn. It's worth noting that in Capture One, LCA correction slightly softened the image (we shot on an OM-D E-M1 III), and since it was so subtle to begin with, we actually preferred to leave the correction off altogether. That's precisely the difference (or less) between the PL25 and the other lenses when stopped down to f2. The corner performance isn't great at wide open too, it is visibly soft and there is light fall-off, or vignetting. analytical cookies to measure visitors traffic to also help us understand which products and actions are more populat than others.
