There's a trend amongst the photography community to start moving towards 40mm lenses. They're the perfect balance between 35mm and 50mm lenses. They're also close to being true normal for full-frame cameras.
The 40mm lens is seriously something that we're happy to see has made a comeback in the past few years. The folks over at Sony, Sigma, and other companies have made them. And honestly, the 40mm lens deserves to live right up there with the 35mm, 28mm, 50mm, and other lens offerings.
The 40mm focal length is one that photojournalists can truly benefit from; and in the case of the Zeiss 40mm f2 Batis for Sony FE cameras photographers will be quite pleased with the results if they're discerning about their look.
