It achieves an attractive and smooth out-of-focus effect when working with shallow depth of field due to the rounded seven-blade diaphragm.

Features like articulating screens, touch screen, touch AF, and 10fps common to even first gen OMD MFT cameras will likely be off the table when venturing into older digital full frame land. As far as same amount of light, the sensor sensitivity does not change the amount of light it's getting. Just like f/number iso cannot be compared across different sensor sizes because it's a per unit area quantity and has nothing to do with the signal of the image.Mu-43 is a fan site and not associated with Olympus, Panasonic, or other manufacturers mentioned on this site. Thanks for sharing - I would need the cat to compare now It's exactly these kind of photos in which I noticed it's really not sharp. Focus shift due to spherical aberration causes a shift away from the camera upon stopping down, and as a result would cause back focus, not front focus. The only external control is the broad ribbed focus ring that moves fairly smoothly and has a decent resistance but lacks the heavy feel of true damping. There's no optical stabilization, though this shouldn't matter for the vast majority of shooters, as almost all modern Micro Four Thirds bodies have internal IS.

So, for light gathering the advantage of the prime over the 14-42mm kit lens is minimal: the kit zoom has OiS while the 25mm prime is not stabilized. You do get a lens hood, but to fit it you first have to take off this ‘decoration’ ring, which seems a bit of unnecessary fuss. And even on the highest resolution 20MP Four Thirds sensors, its resolving power should leave most users satisfied. Add the M43 adapter to the cost and the Panasonic looks to be the bargain of 2019 if its shallow depth of field and out of focus bokeh you are looking for !I'd also recommend testing on a tripod, even use electronic shutter to remove as many possible other sources of problems as possible. Longitudinal CA (LoCA) – or purple and green fringing manifesting in front of and behind the plane of focus – can be fairly noticeable wide open and is hard to manually correct for.

Along the way, he's shot extensively with cameras and lenses of almost every imaginable type, brand and format. The company says the optical formula also includes one ultra-high refraction (UHR) element that helps produce even illumination and sharpness for consistent performance throughout the aperture range. Comprising eight elements in seven groups, the Panasonic 25mm has a more complex optical construction than most lenses with a similar angle of view.Simply put I get distracted by newer, fancier, shinier, and old-timey baubles with which to fritter my time away with. But this chunky yet competent backpack doesn't have a killer feature or look that makes it stand out from some pretty tough competition. Diffraction limiting starts in at ƒ/11, but you probably won't notice any practical impact on sharpness until ƒ/16; even at ƒ/22, images are still decently sharp.

Things may improve with in-camera processing or with software, but the lower sharpness is somewhat disappointing. For reference the lens is quite reasonably sharp in the center wide open (60 lp/mm) and only gets modestly sharper by F/5. It is given away in the title above but this is a lens that both makes no sense and is quite sensible.An inner focus drive system and stepping motor for smooth, silent operation to work with the camera’s high-speed, high-precision Contrast AF system for both photo and video recording.
