Image/Working Distance vs. Magnification - CoinImaging.com
All high-magnification work (above 1:1) will have working distances from 1-2 focal lengths from the center of the lens while typical macro lenses that work up to 1:1 magnification will have image distances from 1-2 focal lengths of the lens.
1. With the camera mounted on the camera stand, carefully thread the 12mm CFF lens onto the camera and adjust the height so that the star target takes up the entire vertical FOV of the image. Measure the working distance (WD). 2. Set the iris of the lens to f/2.8 and adjust the focus until the target is sharp. Snap an image. 3.
Optics basics: Field of View, Working distance, Resolution | Opto ...
Field of View (FoV): total area that can be viewed by the lens and imaged onto the camera sensor. Working distance (WD): object to lens distance where the image is at its sharpest focus. Depth of Field (DoF): maximum range where the object appears to be in acceptable focus. Sensor size: size of the camera sensor’s active area. This can be ...
How to Calculate Lens Working Distance - The-Digital-Picture.com
How to Calculate Lens Working Distance. Minimum focus distance is an important lens specification, but this number does not indicate the working distance, the distance from the end of the lens (or the end of the lens hood if in place) to the subject. This is …
Working Distance - Michigan Technological University
Virtually all consumer digital cameras use minimum focusing distance as the criterion for measuring macro capability. The following table shows some data. These cameras use different focal lengthes for macro shooting. Some of them use the wide angle end, while some use the middle focal range.
Long Distance Working Objectives (LDW) are specially designed lenses intended to provide high resolution imaging and a greater working distance when compared to conventional lenses. The benefit to using these in a macro or micro range is that the configuration provides more room to

How do fixed lenses "focus" on things at different distances?
2019年8月20日 · Lens magnification (focal length) determines how large a point will be when it reaches the sensor. Subject distance determines how large that point is initially (i.e. larger if closer), and therefore affects the magnified result. It is not focus distance per-se, but if the subject is in-focus they are effectively the same thing.
Understanding Focal Length and Focal Distance Difference - Camera …
2024年3月6日 · Focal distance, also known as the focusing distance, refers to the physical distance between the subject you’re photographing and the camera’s image sensor. Unlike focal length, which is a fixed property of the lens, focal distance changes dynamically as you adjust the lens to focus on subjects at different distances.
