Sigma FF High Speed Primes.

The main lenses I used for my recent Sony Venice shoot in Arizona were the  Sigma Full Frame High Speed primes in PL mount.

These are really really nice lenses!

As they cover a full frame sensor such as the one in Sony’s Venice high end digital cinematography camera these are pretty future proof lenses. They are all fast lenses with most of them opening up to T1.5. At T1.5 you have a 20, 24, 35, 50 and 85mm lenses and at T2.0 you can go as wide as 14mm and as long as 135mm.

They are of all metal construction, the build quality is absolutely first class. As soon as you pick one up it just exudes quality. They are not light weight lenses, coming in at between 1kg and 1.3kg in PL mount form, but that weight gives you the confidence that these are lenses that will last. Lenses that will stand up to daily professional use on a film or documentary shoot.  They are dust and moisture sealed, which is probably just as well as on this shoot there was a lot of blowing sand and dust. Our on set photographer was having problems with sand and grit in his lenses by the end of the shoot, but the Sigmas just shrugged it off.

The focus and aperture markings are very clear and easy to read they even glow in the dark! The focus ring rotates through a full 180 degrees and both the focus and aperture rings have standard 0.8 pitch teeth for follow focus controls etc. The gear rings are all the same distance from the mount so there is no need to move the follow focus when changing lenses.

The lenses are available with PL, E mount or EF mounts. The set I had were fitted with PL. The mounts are not user interchangeable, but you can have the mount swapped by Sigma if you do find that you need to change it for some reason.

I shot several scenes with the 20mm lens using the Venice’s full frame 6K x 4K mode. Examining these images in post production reveals that the 20mm is really sharp right out into the corners. I also shot with the lenses wide open in some pretty dark places and even wide open they stay tack sharp. Take a look at the image below, it’s really sharp. If you click on the image you can enlarge it to view it at close to the original 6K resolution.

Shooting night scenes with the 135mm wide open also gave beautiful results. When shooting with a shallow DoF all the lenses have a very pleasing bokeh. This is perhaps in part thanks to the use in all of the lenses of a 9 blade, rounded diaphragm aperture system.

When changing focus mid shot breathing is minimal and the focus ring is silky smooth. A really nice touch is the use of a damper at the focus stops so there is no noise if you hit the end stops.

During the shoot I used the 20,24,35,50,85 and 135mm lenses and they all performed really well. Looking at the footage in the grading suite it looks sharp and there are no nasty distortions. I did notice a touch of barrel distortion with the 24mm but this is to be expected with a wide lens on a full frame sensor. All the lenses matched really well, the colour remaining constant throughout the whole range. The look from the lenses was very neutral. Lens flare was extremely well controlled and I didn’t notice my blacks becoming washed out in high contrast situations. When shooting into the sun or at a direct light source any flare that I did see was normally quite pleasing.

The shot below was obtained shooting towards the sun when it was very low in the sky, yet the lens behaved flawlessly retaining deep blacks and a very high contrast image.

These lenses helped me capture some truly beautiful images with the Venice camera. I’ve long been a fan of Sigmas more recent lens designs. I have several of the Sigma Art Lenses and these have always performed exceptionally well. These prime lenses take things one step further putting world class optics into housings designed for manual control and the rigours of professional film and video productions. They are very competitively priced, especially when you consider that these are full frame lenses. I really hope to be able to use them again on future shoots. They really are top notch lenses and the images I captured with them look gorgeous.

    1. The Sony primes are good lenses and good value, but I think the Sigma’s are better. There are certainly much more robust than the Sony PL’s that have the plastic housings. If I had to choose between the Sonys or the Sigmas I would definitely take the Sigmas.

  1. Thanks Alister, a trustful review I was waiting for.
    If you would have the possibility one day to try out the Schneider Xenons and compare them with the Sigmas, it would help me to make a final decision that already took me a year of headache. At the moment shooting with the FS7 and A7S, but will be future proof.

    1. I shot with the Xenons a couple of years ago. I would say the Sigmas are sharper and higher resolution, but that perhaps the Xenons have a bit more character. Right now I would probably go for the Sigmas.
