Before I went to Arizona to shoot the monsoon thunderstorms and Grand Canyon I felt that I would need a nice fast wide angle lens to help capture some of the panoramas and vistas that I would see. A little while ago my friends at Alphatron told me about an E-Mount wide angle lens that was soon to be launched. So after a couple of phone calls I managed to secure the loan of one of the SWV-E11-16 cine style E-Mount lenses. Even before opening the box I knew this was something a bit special as the box was pretty heavy, no lightweight plastic lens in this box. On opening the box I was not disappointed. Inside was a very solid looking cine style lens with substantial gears on the focus, zoom and iris rings. This isn’t really a zoom lens, more of a variable focal length lens. The difference between the field of view at 11mm and 16mm isn’t all that great, but it does allow you to vary the framing.

As this is an E-Mount lens, not only does it work on the FS100 and FS700 but it also fits on any other E-mount camera such as my NEX5N.

This isn’t a lightweight lens, it is a substantial, beautifully constructed lens that is a real pleasure to use. Compared to a typical DSLR lens the focus ring has a much greater travel which makes accurate focus much easier to achieve. The 0.8 mod gear rings allow the use of standard follow focus systems so no need to use add-on adapters. I can’t stress enough how nice this lens feels to use. But the feel of a lens is only a small part of the story, of course it’s the image performance that is what’s really important and again the Zunow does not disappoint.

I used it in various light conditions from bright desert sun to after dark. The wide f2.8 aperture makes this quite a fast lens considering it’s wide field of view. Most ultra wide lenses tend not to be as fast as this. When set to 11mm there is some noticeable barrel distortion which is really surprising and it’s not particularly objectionable as you zoom in to 16mm this distortion decreases to very low levels. This is one sharp lens. The images from this lens, both stills and HD video show huge amounts of crisp clear details.

The best performance was from f4, but even fully open a f2.8 the centre of the image remains sharp and with good contrast. There is some slight softening in the corners at very wide apertures but this is not severe and I felt that the lens was perfectly useable even at f2.8 unlike some other wide angle lenses I have used. Colour fringing and chromatic aberrations are well controlled and I didn’t observe anything objectionable.

I really liked using this lens. It has the feel of a high end PL mount lens and performance to match. It looks the part and looks like it will last a very long time. I was very sad to have to hand it back after the shoot. The European distributor, Alphatron, tell me that as well as this E-Mount lens, Zunow are planning on producing PL mount versions as well as  additional similar lenses of different focal lengths.
