Remarkably High Contrast Corner to Corner
The very first 25mm lens Carl Zeiss has engineered in a Canon EF mount; even the 25/2.8 Distagon was never even available in a Canon mount, only for Nikon, however a Nikon 25/2.8 Zeiss Distagon can be mounted on Canon using a lens adapter.
With special glass types and a pair of aspheric elements, Carl Zeiss has obviously gone the extra yard by designing a superb 25mm lens.
The MTF chart indicates this newly released 25/2 can is expected to become a very big performing 25mm f/2.0 lens, and feature remarkably high contrast from corner to corner and it will be competing directly with rangefinder lenses, I'd say quite some feat, while it drops off just in the acute corners. From what I see, It should be one stunning performer.
This 25/2 Distagon lens is more compact than the Distagon 21/2.8 . Also, 67mm filters don't cost as much as 82mm filters, and pair up with the100/2 Makro-Planar than a 50/2 Makro-Planar. However 21mm provides quite a bit more wider viewing angle, so having both of these focal lengths isn't unpracticle. However, if it's used as an all-purpose lens, I’d think that 25mm is better suited for most users than an ultra-wide 21mm, while the f/2 aperture creates some additional flexibility as well.
