I continue to thoroughly enjoy shooting with the little Loxia 21. It is as close to a 'Leica' glass feel as I have experienced with the Sony A7rii. I have a running set of images on my stories site with sample images so please jump over there for more imagery from the A7rii/Loxia 21 combination.
In a few words or less, this is a simply stunning lens. The build quality is spectacular. The aperture ring and focus ring are buttery smooth, which makes manual operation a dream. Paired with the A7Rii peaking and zoom capability, focus is easy, quick and very precise.
If I had one nit about the lens, it would be what others have already stated. The mount is just a bit small for removing the lens. If it were a tad bigger, with more separation from the aperture ring, removal of the lens would be just like any other lens. However, due to its small size, removal is a tad difficult. All in all, I would say that is purely a minor complaint and one that is easily overcome with practice.
I will continue to update my story site over the next several days with images and then I move on to testing out the Zeiss 25 Batis; the Sony-Zeiss 35/1.4 and the Sony 35/2.8.
