​The Zeiss Batis 18mm F2.8 is a native full frame lens for Sony E mount cameras. The lens is surprisingly lightweight for its low distortion, wide angle, moderately large aperture for a lens at this focal length, and the inclusion of auto focus. The Batis 18 is physically larger than the Batis 25, but the size is not indicative of the weight. The lens weighs 330 grams, which is 5 grams lighter than the Batis 25.

I purchased the lens and traveled to the Columbia River Gorge in Oregon to capture photographs of some of the best waterfalls in America. Spending nearly 100% of the time mounted on my Sony a7Rii, this lens did not disappoint. The lens is sharp and weather sealed which is important when most of your time will be spent in and/or around water. Zeiss has been on point with the Batis line and the Batis 18 may be the standout lens of the available current trio when talking performance. The Baits 18 accepts the standard Lee Filters 77mm adapter ring without issue. There is NO need to get the Lee Filters 77mm wide angle adapter ring to use with this lens.

We hiked forty miles in four days and I would consider the Baits 18 a top option for a low weight, high quality hiking kit. If you are trying to cut further down on weight this lens performs great on the Sony a7. Despite getting a fair amount of water spray and splash on the lens body and front element, I had no issues with the performance of the lens itself. The LED display is nice but the distance scale is close and nothing that you should use for critical focusing.

All of the before mentioned qualities of the Batis 18 make it a wonderful lens to hike with and photograph waterfalls when needing an 18mm focal length. The contrast and sharpness of this lens are very good. 

With autofocus, ability to use standard ND filters, lightweight, and stellar performance across the frame, the Batis 18 is going to be a hit with wide angle enthusiasts and the hiking crowd.
