7Artisans goes wide on the RF mount

7Artisans is one of those Chinese lens manufacturers that have popped up in the last 10 or so years. I played around with 7Artisans on the EOS-M mount, and they were pretty fun bang-for-the-buck lenses, but quirky ergonomics.

7Artisans is known for its manual focus, and manual aperture lenses, and this 9mm F5.6 full-frame lens is no different. However, with 16 elements and 11 groups, it’s not exactly a simple lens either.

The craziest thing about this lens? It should cost somewhere around $375 if this specification sheet is correct. What grabbed my attention was the MTF data. If this is actually what this lens can do, it’s a pretty good lens. Yes, it’s all manual but who needs AF at 9mm anyways? As an example, the widest Canon-made RF lens (Canon RF 14-35mm F4L) falls off more to the corners and has greater astigmatism according to the MTFs – and it’s 14mm versus 9mm.

Craig actually has the lens, so hopefully, we’ll be updating this post with some real-life examples.

This has the makings of a very interesting lens for the RF Mount.
