Panasonic is working on developing a very fast wide-angle LEICA zoom-lens. The Leica DG Vario-Summilux 10-25mm F/1.7 is being touted as the world’s first full-range f1.7 wide angle zoom for the Micro Four Thirds (MFT) system.
The lens is aimed as a perfect compliment for photo/video shooters. Much like Sigma’s 24-35mm F/2, the Leica DG Vario-Summilux 10-25mm F/1.7 is more like a variable prime than a zoom lens. With a 10-25mm ((35mm camera equivalent: 20-50mm) focal range and constant f1.7 aperture, it is sure to find its way onto a lot of M4/3 cameras once it becomes available. While Panasonic has probably made it with the GH5 and GHs in mind, it will be right at home on the BMPCC 4K, although the lens doesn’t feature IS.
The lens will feature an integrated click-less aperture ring for smooth iris adjustments. The lens features a 77mm front filter diameter so you will have no problem using a variable ND on the front. There is little more known about this lens and the date of release and price are still unknown.
The Leica DG Vario-Summilux 10-25mm F/1.7 looks to be a better option if you are looking for a fast wide angle zoom for your M4/3 camera than say the Olympus M. Zuiko Digital 7-14mm f/2.8 PRO, or Panasonic Lumix G X VARIO 12-35mm f/2.8.
