Parfocal Cinema Zoom lenses are expensive, and most rent them when needed for a project. DZOFILM is out to change this with its affordable cinema zoom lens offerings. The first set released was the Linglung Series 10-24mm & 20-70mm T2.9 parfocal lenses for Micro Four Thirds mount cameras. The set runs only $2,998.00. That’s not a typo—two parfocal cinema lenses for under $3K. I haven’t tried these yet, but the reviews have been positive, especially for the price.
Let’s dive into the S35 Pictor Zoom 20-55mm T2.8 & 50-125Mm T2.8 lenses.

When I first held one of the Pictor Zooms, I was surprised. It has a nice build with all-metal housing. The dampening is firm and not sloppy. Very nice mechanics all around. I did notice a little stickiness on the top beginning and end of the zoom. It didn’t affect the performance when using motors.

The two lenses match with focus, zoom, and iris rings all in the same position for easy lens swaps when using a follow focus of motors. The length of the 50-125 is a little longer, so a swing-away matte box will need adjustment.

What’s Included

2 lens Kit

The DZOFILM Pictor Zoom cinema lenses come in a kit with a nice case and all the accessories needed. They are available individually as well. The set retails for $4,499.00, or 20-55mm T2.8 retails for $2,289.00, and the 50-125mm T2.8 is $2,489.00

DZOFILMS Set
Available in white or black.

The hard case has firm laser cut foam to keep the lenses safe when transporting. Additional cutouts are for the included EF mounts, two screwdrivers, lens supports, and shim cases. The full kit is a thing of beauty.

PL and EF mounts

EF Mount
The 2 lens kit comes with EF Mounts as well as PL

The kit includes both PL and EF mounts. It shipped with the PL mounts, so I had to swap them out as I dont have a camera with the PL mount system. It’s great that DZOFLIM includes both mounts as rental houses will be swapping the mounts out frequently, as well as owner/operators who rent PL or EF mount cameras. It’s really a win, win.

The mounts do not have electronic contacts; therefore, they dont speak to the camera, so no iris and focal length data will appear in the camera monitor or EVF.

Parfocal Back Focus Adjustments

Shim the Pictor Zoom
Swapping out the PL for EF requires changing the shims

To get the Pictor Zoom to perform as a parfocal lens, the back focus must be adjusted using the supplied shims. It’s fairly tedious since you have to unscrew the eight T6 torque screws off the mount, add scrims, then put it back together and test.
Since I was swapping out the PL mount for the EF, I didn’t have a baseline to work with, so I started with the 0.30 shim and added more after determining the parfocal performance. You have to be careful when handling the shims as the thin ones are very fragile. You dont want to crease them accidentally.

Pictor Performance

I’m not a lens tech or pretend to be one. I did some simple tests with a chart to see how the lenses perform. My tests are not scientific. I feel they are still relevant as it helps me see the actual performance in a controlled and rather boring setting.

My favorite focal range is around 50mm to 200mm. I shoot people mostly, so wide angles don’t get much use in my world, but telephoto lenses do. Let’s start with the 50-125mm and then the 20-55mm and see how the lenses look shooting a chart. I know you can’t wait!

Distortion, Sharpness & Chromatic Aberration

One thing that does stand out to me is the Pictor Zooms are warm in color. I prefer warm over cooler as I shoot faces most of the time. The lenses are also somewhat soft, or not clinically sharp, so that is two features I like a lot.

Pictor 50-125

The 50-125mm has significant distortion at 50mm, and it decreases as you zoom in. At 125mm, it’s still present.

Below is the 50-125 at 125mm. You can see the distortion in the corners and some chromatic aberration as well in the center.

f2.8 at 125mm 300% crop shows some CA.

Once you stop down around T5.6, the corners get sharper but never match the image’s center sharpness. I would say the sweet spot for sharpness at 50mm is a little past T4 to f11.

Pictor 20-55mm

At 55mm, T2.8 distortion is reduced, and CA is also present in the center and corners.

The sweet spot for the 20-55mm is T8. The corners become sharper with less CA present. The lens also has distortion present at 20mm and performs better at 55mm.

Thoughts on Distortion & Sharpness

While you might think these results are not good, it’s a test using the most boring thing ever. A chart! If you are shooting all flat walls with no depth, then these are not the lenses for you, but this isn’t the case at all. In real-world shooting, the subject is the center of focus, and the scene will have depth and be out of focus, depending on how wide open your shooting and the length of the lens. Overall, both lenses are on the softer side and, at times can be harder to focus due to the character of the lenses. These are not clinical lenses. If you like vintage lenses, you will like the Pictor Zooms.

The Pictor 50-125mm sharpness falls off quickly to the corners when shooting wide open at T2.8. It gets better as you close the lens down, but it is still rather soft. I would say the center third portion of the lens holds well but quickly gets softer as you move to the frame’s left and right sides.

Chromatic Aberration is difficult to fix in post. I did see some in the detail areas of the corners throughout the zoom range. It decreases when stopping down.

Below are all the f-stops at the long and short zoom range for each lens.
