Mirrorlessons reviewed the new [shoplink 44222]Loxia 21mm f/2.8 lens[/shoplink] and writes:
The Loxia 2.8/21 delivers exactly what you’d expect from a Zeiss lens. It is sharp at the centre, sharp in the corners, handles flare like a pro, and doesn’t show any relevant traces of CA. There is some slight vignetting at f/2.8 but it can be easily corrected with any software. As such, it doesn’t really qualify as a negative point since it happens with almost every wide angle lens. The only thing I couldn’t test because of the bad weather was coma aberration for astro images.
Of course, we could also talk about the price. This lens is not cheap by any means but if you look at the entire Zeiss catalogue, you will find that it fits in the usual price range applied to this type of lens. The Milvus lenses or old classic ZF/ZE versions are actually more expensive. So yes, the price is high but the lens delivers exactly what it promises.
