PANASONIC LUMIX G II Lens, 20MM, F1.7 ASPH., MIRRORLESS Micro Four Thirds, H-H020AK (USA Black)

Product Information

Panasonic’s 20mm f1.7 II is an autofocusing beast on the GH4 when using the fully automatic focusing modes and not choosing a point beforehand. In fact, we think that it is the fastest focusing lens that we’ve seen for street photography. But when you mount it on the OMD EM5, it starts to lag a bit behind. Once you start selecting specific focusing areas, the focusing speed goes from sloth-like to peregrine falcon. Image Quality

The original Panasonic Lumix G 20mm f1.7 ASPH was one of the most prized lenses for both Panasonic and Olympus users and the announcement of a revamped model with the same optical construction was a surprise. The Panasonic Lumix 20mm f/1.7 lens gives a 40mm equivalent, and makes it a pleasing lens to use for portraits. 1/4000s, f/1.7, ISO125, 20mm. As one should expect at the price point, this 25mm offers a bare-bones feature-set. 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. Nor is there an aperture ring or custom buttons. What the lens does offer is a sizable focus ring.Lens flare can cause some loss of contrast especially when shooting directly into bright light sources, while multiple ghosts of bright sources can manifest themselves as colored 'blobs' that get more defined the more you stop the lens down. No doubts it's good lesson for all competitors. "That's what I call the lens" =) Small, sharp and fast. Very good, contrast

For a 20mm lens, we found the distortion control to be pretty good overall. In fact, unless you’re going to sit there pixel peeping (and it’s really dumb to do so when your clients are doing so) then that’s the only way that you’ll have a problem with this lens. Beyond this, most street photographers don’t sit there speaking about megapixels all day–instead they focus on capturing moments. Even when shooting with the included lens hood attached, artifacts from lens flare can be pretty distracting with this lens. You may notice ghosting when shooting directly into the sun, usually manifesting as a multiple-color haze or purple blobs. If there's a weakness in the lens, it would be significant corner shading when used at larger apertures. This is especially noticeable when used wide open, where we note corners which are a full stop darker than the center of the image. This light falloff reduces as the lens is stopped down, becoming 3/4 of a stop at ƒ/2, and 1/2 a stop at ƒ/2.8. At ƒ/4 it remains more or less constant at a third-of-a-stop of light falloff.PAST BYLINES: Gear Patrol, PC Mag, Geek.com, Digital Photo Pro, Resource Magazine, Yahoo! News, Yahoo!

The closest focus on the 20 1.7 is a really nice 0.2 meters. Thanks

The Google Pixel 6 may not be the latest Google smartphone any more, but it might still be the best value The out-of-focus regions in this F1.7 shot show some purple fringing in front of the subject, aka longitudinal CA (LoCA) This close-up photo shows both how close you can get to an object, as well as bokeh. 1/1600s, f/1.7, ISO200, 20mm.

Wide open is just magic. The Xiaomi 12T Pro offers a whopping 200MP main camera, but how does this perform, and do the other cameras deliver? Joshua Waller puts it through its paces.
