Any time anybody comes out with anything new, I get excited. Whether it’s something I’m expressly interested in or not, I get excited. So when Sigma announced that they were coming out with a Sigma 30mm 1.4 for the smaller DX style image circle but it was for Micro 4/3 and Sony E-mount. I was happy that the systems were getting some attention, even if I had never intended to go look at this lens in a store. And then, Sigma contacted me and asked if I wanted to try it out. Of course I said yes, and I was ready to head into the unknown world of a Sony body with a Sigma lens. What was I thinking!

To be honest I really didn’t know anything about the Sony A7s, nor would I ever have looked it up before being handed one in Roberts’ downtown location. I was surprised as to how compact the A7s was, and the Sigma 30mm 1.4 lens was what I would consider to be a standard sized lens for the package. First of all, the A7s was a great camera for this test. It’s 12 megapixels and full frame. This is a lens designed for crop sensor cameras, (Sigma calls it DC), so if you were to shoot full frame with it, you get this nasty vignette as shown below.

The A7s IS capable of being put into DX/DC mode, but the shots are only 5.1 megapixels like that. This is good and bad. It’s good because now I can see how the new Sigma performed, but my files are incredibly small.
That said, the Sigma killed it. I wish all my F1.4 glass focused this fast and this well on my Nikon bodies.

The Sigma had zero trouble keeping up with moving targets even on AF-S(ingle). The continuous autofocus on the Sony seemed a bit ‘off’ to me, so I decided to just use the single focus and never looked back. The camera was surprisingly hard to trick, even at F1.4. All the shots I wanted were nailed and even the shots I decided I did NOT want were nailed. Very few were out of focus for reasons other than my own stupidity and this shocks me because if you put my Nikon 24 F1.4 or my Sigma 35 1.4 Art on my one of my Nikon bodies, there is always a way to trick them into being out of focus.

As it comes to sharpness, current technology has made it so that any lens needs to be sharp in order to make it. The New Sigma 30mm 1.4 DC DN C does not disappoint, and mounted to the Sony A7s it’s practically a dream combo since the A7s can practically see in any light. Having never used the Sony camera before this test I can tell you that I was quite impressed with how it handled the Sigma 30mm 1.4 DC lens, and in any light I could see this being a killer combo.

Here is the rub. I don’t shoot Sony. I very rarely come into contact with a Sony camera. I can tell you for 100% certain though that if I owned a Sony SLR, I would own the NEW Sigma 30mm 1.4 DC DN C. It’s a dream combo. Walking around snapping away in any light with almost guaranteed accuracy of the AF was incredible. I’m not sure how much can be attributed to either the camera or the lens, but 100% sure these should go together. Maybe Sony needs to work with Sigma on selling these 30mm lenses with bodies as a package deal because I can’t imagine using anything else being this good. We will get to see if I’m wrong though, I’ve got something on the way that will put a Sony in my hands for a few more weeks once again. Until then though, I dream of a lens like this 30mm 1.4 DC DN C that works as well on my Nikon bodies.
Consider the bar raised with this one.
