I was initially torn between the Batis 18 and the Loxia 21. I had a lot of trepidation contemplating the purchase of a manual focus lens, especially to pair with such an advanced camera system such as the Sony A7Rii.

Fantastic performance in a small package. My only complaint is the tactile issue of focus and aperture. It's hard to go from one to the other with the camera at eye level, as both the control rings are relatively smooth and the same diameter. I also use manual focus Zeiss Contax lenses.

I got this for the Sony FS7. I was looking for a lightweight lens with a wide angle of view that had a lot of resolving power. This lens on the FS7 sensor translates to a field of view of almost 70 degrees, which is equivalent to what a 32 mm lens would get.

Optically amazing but the focus ring locked at infinity in freezing cold temperatures and then it kept locking on me. The lens is also painted black with a thin layer of paint and I got scuffs on it from regular use in a couple of weeks. I was expecting a lot more from this.

Great product, works perfect with A7R2. Love how it renders lights, very good built. Easy to focus. Aperture can be changed accidentally when unmounting the lens from camera. Images are great from it

I use this lens primarily for traveling. I can tell you the lens is incredibly sharp on the A7rii brings out more detail than i could've imagine. The lens also has very accurate and contrast colors, slightly on the cooler side, but can also be tweaked in Lightroom/photoshop later if you don't like...

After researching lenses for over a month. I finally settled on the Loxia line by Zeiss. These lenses are made to last a lifetime. When you hold one in your hand you can feel the build quality. The fit and finish is really nice.

I've heard so many good things about the Loxia 21 compared to the DSLR version, the Distagon 21/2.8, that I've been using on my A7RII. I expected the Loxia to be better, but...what a difference. Center sharpness is similar, although I'd say with a slight edge to the Loxia.
