Introduction
Thank you for purchasing this product!
Pictor series is a set of high-performance S zoom lenses produced by
DZOFILM. Good representation of details, vivid colors and smooth transition of image
as well as can be characterized in this series of lenses. They are suitable for different
kinds of projects, documentary, MV, commercials, films, live broadcast etc, bringing
audience with pure and vivid image texture and natural transition of focus shiing.
Safety Notes
Please do not watch the sun or bright light source through the lens, otherwise
it will cause visually disabled.
Never use organic solvents such as paint thinner or benzene to clean the lens.
Attach the front and rear caps when the lens is not in use.
Store the lens and filter in cool, dry locations to prevent mold and rust. Do not
store in direct sunlight or with naphtha or camphor moth balls.
Please keep the lens dry and wipe the water droplets off if there are water
droplets on the glass surface.
Leaving the lens near heater or in other extremely hot locations could cause
damage or warping.
Use a blower to remove dust and lint from the glass surfaces of the lens or
filter. To remove smudges and fingerprints, apply a small amount of lens
cleaner to a soft, clean cotton cloth or lens-cleaning tissue and clean from the
center outwards using a circular motion. Do not leave smears or touch the glass
with your finger.

Focus Control
Rotate the focus ring to increase or decrease the focus distance.
Zoom Control
Rotate the zoom ring to zoom out, increasing the area visible in the frame or zoom in
on the subject so that it fills a larger area in the frame.
Aperture Control
Rotate the aperture ring to stop aperture down, raising theT-stop and narrowing the
aperture, or lower theT-stop to widen the aperture.

Flange Back Adjustment
Note : You can download and print the chart on DZOFILM website-Download-Star
Chart for Adjusting Back Flange（Click to jump to the website）
Step Two : Aach the lens to the camera;
Step Three : Select the maximum aperture (wide open);
Step Four : Set the object .maway from the camera sensor plane, and adjust it
to the center of the whole image.
.Preparation
.Flange Back Adjustment
Every Pictor lens will process flange back adjustment on standard. But to the
tolerance of different cameras, to achieve the best performance of this product and to
match the cameras, please adjust flange back of the product.
Step One : Rotate the zoom ring to the longest focal length, and rotate the focus
ring until the image to its clearest, mark down the focusing distance S;
Step Two : Rotate the zoom ring to the widest focal length and rotate the focus ring
until the image to its clearest, mark down the focusing distance S;
Step Three : Compare the difference between S and S. If S<S, then need to add
shims; otherwise decrease the shims,
Note : The shim adjustment is evaluated on the angle between S and S. If the
angle is bigger, then need to change more shims and vice versa.
Step Four : Repeat step until S=S.Then it means the lens in under parfocal.
Step One : Ready your subject. You can use a "Star Chart", or other high-resolution
black-and-white objects;

Rotate the focal length to mm, and focus till the image is at its sharpest, the
focusing distance mark is .m (S). And then rotate the zoom ring to mm, re-focus
to the image at its sharpest, current focusing distance mark is .m (S). S<S.
According to the sheet below, add .mm shims on the lens mount and double check.
At this time, both mm and mm focus at the closest under . focus mark. That
means this lens is under parfocal.

1.准备工作
2.调节后焦
重复 1-2 步骤，直到S2等于S1时，说明镜头已处于齐焦状态，完成后焦
调节。
准备好拍摄对象。可使用“星状测试图”，或使用其他黑白相间的、对比
度较高的拍摄对象；
步骤二 ： 镜头安装到相机或摄影机上；
镜头调整为最大光圈；
将拍摄对象放置在距离相机成像面约1.5米处，并调整其位置在画面
中心。
步骤三 ：
步骤四 ：
步骤一 ：
步骤一 旋转变焦环至最长焦端，然后旋转对焦环至画面最清晰状态，记下此时
的对焦刻度值S1；
：
步骤二 旋转变焦环至最广角端，然后旋转对焦环至画面最清晰状态，记下此
时的对焦刻度值S2；
：
步骤三 对比S2与S1的大小，若S2小于S1，则需要增加后焦垫片；若S2大于S1，
则需要减少后焦垫片;
：
步骤四 ：
提 示 垫片的调整量与S1，S2的差值对应的对焦环旋转角度有关，旋转角度
越大，需要调整的垫片越多，反之亦然；

绘梦师系列镜头在出厂前会按照标准调整后焦，但不同摄影机的法兰距在出
厂时可能会有一点不同，为了方便与不同的摄影机匹配，达到最佳成像效果，需要
进行后焦调节操作。

6
以Pictor Zoom 50-125mm为例，假设镜头变焦至125端，对焦至画面最清晰时，
对焦刻度值为1.5m，再将镜头变焦至50端，重新对焦至画面最清晰时，对焦刻度值
为1.4m，比1.5m小，参考下方“后焦垫片调整参考表”，将后焦垫片增加0.12mm后，
重新确认，125端和50端，画面最清晰时对焦刻度值都在1.5m，说明镜头已处于齐
焦状态，后焦调节完成。
例：
将拍摄对象在距离相机成像画面“Φ”标记处约1.5m放置，
将拍摄对象位于画面中心。
