Testing The Sigma 50mm f1.4 DG HSM ART Wide Open With The C100

Sigma 50mm and C100 Duzi

This article isnt a full review but more of an experiment /test and my impressions of the Sigma 50mm F1.4 ART.

After having a pre order in since the first day the 50mm was announced I received it a day after a big commercial shoot. I was so bummed! It would’ve been a perfect shoot to use this beauty. I’m still healing from shoulder surgery I had four months ago, so I can’t shoot solo yet. No AC hanging around to take with me, but I really wanted to see how this lens performs with my C100.

Since roaming San Diego with a C100 wasn’t an option I decided to stay home. Now I don’t have cats so the next best thing is flowers and a fountain. I set up a few shots and even pulled out my Cinevate Duzi slider. I’ve been wanting to try shooting 60i for slow motion so I did just that. I was surprised the C100 did not require a new card like the C300 does when you change framerates. It’s the last shot in the video. Not bad right? and super easy. Just drop the clip on a 24p timeline and slow it down by 50%

I’m kind of blown away by how nice this Sigma 50mm ART lens is. It’s a beast of lens but I’m fine with it since it is so nice and FAST! Since I don’t have the Dual Pixel AF on my C100 I wasn’t able to test it, but it does perform as it should on the 70D except it clicks like crazy in continuous AF mode in video.

The next thing I noticed is the focus ring. Buttery smooth and very easy to focus manually. Full range is about a 1/4 turn. I didn’t use a follow focus on this shot just peaking on the C100 and the Atomos Ninja Blade for a monitor. I setup my C100 magnification to blue peaking in black and white. Makes nailing focus fast and easy. The Atomos Ninja Blade is a great monitor too.

I set the C100 profile to Wide DR and did a manual white balance. I graded the image to give it some pop but no sharpening was done only levels was adjusted to tune the image with Colorista II in Premiere Pro CC.

This entire video was shot at F1.4. Why? Because I wanted to! Ha! Very impressed with this lens. It’ seems like very little vignetting is present. In fact I can’t see any. I know it has to have some but dang it looks good. The focus distance is around a foot making these tight shots easy and the backgrounds nice and milky soft. I like the soft silky out of focus areas that the Sigma renders.

This is the benefit of using full frame glass on a S35 sensor. We get the sweet spot of the lens. I cant wait to get this lens out on a production shoot. It’s the fast 50 I’ve been waiting for.

Bokeh? The 9 blade iris creates beautiful bokeh. The picture below was captured at F2.5.

Doesn’t it look like a nice fit for the C100? Thats a plus if you like to use a matte box or follow focus. Plenty of room to get the bits on.

Now I have two Sigma ART lenses. The APS-C 18-35 is another winner. I get a lot of use from just that one lens. Sigma is really making great optics at a very competitive price. I’m thinking about picking up the 35mm ART too! The 50mm ART is being compared to the Zeiss OTUS and that lens cost $4K. I’m looking forward to the next ART lenses Sigma has in the works. Maybe a 85MM? or a 100mm macro? I’m in!

    A question… being relatively new to My C100 and Large Sensor shooting, could you talk a little bit about the “sweet spot” that you mention in this post? Thanks Erik

    • Erik Naso says:

      The “sweet spot” is the center of the lens where it’s image is best. As you go out and to the corners you will see distortion and sharpness decrease. Since the C100 is S35 it never sees the corners of full frame lenses.

  2. Thanks for the great review. Would love to see how this compares against the Zeiss 50mm Planar 1.4.
    BTW – Who makes the eye cup that you’re using not your C100? Have seen a few options out there, but hard to know if they’re useable or not.

    Keep up the great work!

  3. I love the look of these lenses; the 35 f1.4, 50 f1.4 and 18-35 f1.8 are all on my wish list.

    I’ve waited patiently for the Sony alpha mount version of the 18-35 because I have Sony cameras (FS700 and A6000) and with the Sony LA-EA4 adaptor this should give me solid phase detect autofocus on the FS700, which I’m hoping will make solo Steadicam work a lot easier (assuming it locks onto a face properly like it’s supposed to do).

    You mentioned crazy clicking with continuous AF on your 70D, does your 18-35 do this too? I’m just wondering given my potential use case for the 18-35 (Steadicam), because unless radio mics are employed, then the on camera mic will be pretty close by.

    I really hope you get back to full health soon. Be well!

    All the best, Jamie.

    Thanks for the grat review. Now i have one. I’m soooo happy. I beats anyone. By the way, it works smooth an quiet with the Dual pixel AF.

    Thanks for this review but one side question: looking at the pics of your gear, you seem to have added an extra base plate under the top handle of the C100. I guess it’s a way to grab the arm of your Ninja. Could you tell me where does this extra base plate come from?
    As a owner of the C100, I’m pretty interested to know, to find a discreet way to put also an Atomos (but rather a Ninja Star than a Ninja 2).
