What is a leaf shutter? How does it work?
The leaf shutter is built into the lens structure. Its most significant advantage is that it can achieve flash synchronisation at all speeds (e.g., if the max shutter speed is 1/2000s, the flash sync speed can also reach 1/2000s). This helps capture fast-moving subjects when a flash is used and is also helpful for portraits using maximum aperture in strong lighting conditions or outdoors. Due to the unique design of the leaf shutter, it generates significantly reduced vibration when triggered, efficiently producing quality shots.
For cameras with a focal-plane shutter, when using flash, the shutter speed is limited to 1/125s or 1/250s, which can limit creative possibilities.
Why does the shutter of the XCD 3,4/75P sound differently from that of the XCD 2,5/25V?
The XCD 3,4/75P uses a smaller shutter module, the same as those in the 55V and 38V lenses. This shutter module can achieve a shutter speed of 1/2000s, and its sound is very soft, making it suitable for shooting in quiet environments.
Does the XCD 3,4/75P lens support full MF?
Yes. Full-time manual focus is always available. Adjust the focus ring at any time, regardless of whether you use AF or MF mode.
How do I correct lens distortions?
Distortions can be corrected in Phocus or other image-processing software for more accurate optical effects. The camera itself does not support lens correction.
What is the equivalent focal length of the XCD 3,4/75P lens?
The equivalent focal length is approximately 59mm.
What is the optical structure of the XCD 3,4/75P lens?
Ten elements in ten groups, including one aspherical element and three ED elements.
What focus motor does the XCD 3,4/75P lens use?
A linear stepping motor.
What is the focus type of the XCD 3,4/75P lens?
Internal focusing.
What are the weight and size of the XCD 3,4/75P lens?
XCD 3,4/75P weighs 398g and measures 75 x 76mm. For more details, refer to the datasheet.
What is the filter diameter of the XCD 3,4/75P lens?
XCD 3,4/75P adopts a filter thread with a diameter of 72mm, which supports installing all types of 72mm-diameter filters.
What is the ingress protection rating of the XCD 3,4/75P lens?
XCD 3,4/75P includes some sealing at the seams, but it is not rated for dust or water resistance. It is recommended to avoid using this lens in dusty or wet conditions.
What is the close-up capability of the XCD 3,4/75P lens?
The minimum focusing distance of XCD 3,4/75P is 55cm (measured from the image plane), with a maximum image scale of 1:5.8.
