Description

LEICA DG VARIO-SUMMILUX 20-50mm / F1.7 ASPH. H-X2550 lens is built for mirrorless Micro Four Thirds (MFT) mount cameras, enabling F1.7 aperture brightness throughout the entire 50-100mm (35mm camera equivalent) zoom range. Its exceptionally high optical performance is suitable for both professional photographers and videographers. Comprising 17 elements in 12 groups, the lens system features three aspherical lenses and four ED (Extra-low Dispersion) lenses that effectively suppress the axial chromatic aberration and chromatic aberration of magnification. Spherical aberration and distortion are also corrected by the aspherical lenses for stunningly high resolution. The use of aspherical lenses and the optimum design of the lens system results in a compact size and light weight. Compatibility with a maximum 240-fps high-speed sensor drive realizes high-speed, high-precision auto focusing. In addition to the silent operation achieved by the inner focus drive system, the stepless aperture ring and micro-step drive system in the aperture control section help the camera to smoothly catch up to brightness changes when zooming or panning. The optical design achieves exceptional barycentric stability to minimize image shifts during zooming. A focus ring is equipped for intuitive, precise focusing and linear/ non-linear setting can also be switched with this ring.

  • Incredible…
Incredible. Needs a ND to shoot 1.7 in broad daylight. Replaces a bag full of primes.

  • Versatile and perfect!
I have not removed this lense from my GH7! I love it's versatile nature, clarity, and that bokeh!

  • Good but heavy lens
An amazing lens that can do everything and its super clear. The only thing is that its a pretty heavy lens but its got to be I guess when it can do so much with high quality pictures. Used it with my Panasonic Lumix DMC-G7.

  • 1.7 Butter!
If you want a lens for the micro 4/3 system...YOU HAVE FOUND IT!. Buttery wide open! Love it and next is the 10-25.

  • Truly an Amazing Lens
This lens, like its 10-25mm sibling is truly outstanding. This lens is reason alone to invest in the micro four thirds system. Nothing like it exists for any other sensor size. Between the two of these lenses, almost all of my needs are covered. Image quality and rendering is on another level. Focus falls off in a beautiful way. The lens is outstanding for both still and video. The smooth, click less, aperture ring is a joy to use. The only downside is, it is on the larger size for a micro four thirds camera. It does feel well balances on a GH6 or G9. If you need something smaller, consider another lens like the Leica 12-35mm f2.8 and 35-100mm f2.8 pairing. This zoom lens truly replaces a bag full of primes. A must have. ... show more

  • It's superb
This isn't a "review" - there are plenty of those on the web. The lens is what I expected it to be, based on reviews I've seen. That is to say that it's excellent. The $300 off offer :-) made it an acceptable price.
