We proudly present a new member of the SPECSGROUP: FOCUS. As a long established manufacturer of e-beam evaporators, momentum microscopes, e-beam welding machines and many more, FOCUS is now a strong brand of the SPECSGROUP as of July 2024. Their products and expertise is a welcome addition to our existing portfolio with their team in our new subsidary in Hünstetten.

A lens suited to most subjects, from portrait to landscape. There is minimal distortion and can use large apertures down to f/1.8, etc. Good for portrait, nature, low light, and general use.

Technically, focal length is the distance between the point of convergence and the camera sensor, but that’s not a particularly easy way to understand it. Instead, imagine a simple lens with one piece of glass focusing the light onto the sensor. The distance between the lens and the sensor is the focal distance. So, in a 100mm lens the distance between the glass and the sensor is 100mm. It’s as simple as that.

Depth of field, how much of the shot is in acceptable focus, changes with focal length. Shorter focal lengths not only capture a wider view, but they also have a deeper depth of field. They can capture almost everything from right in front of the camera to infinity in acceptable focus. As focal length increases the depth of field decreases, so a longer lens captures a narrower band in acceptable focus.

focallength中文

Short focal length lenses have a wide angle of view, hence the name “wide angle”. Longer focal lengths have a narrower angle of view, covering a smaller area of the scene. That’s why long focal length lenses seem to magnify the image - they capture a small part of the scene but still fill the sensor with it. A focal length of round 50mm is generally accepted as being about what our eyes see, which is why a 50mm lens is so often the standard lens that comes with the camera.

Distortion is small – vertical lines may curve but can be corrected later. It’s good for journalistic and real estate work because the angle of view is huge and so much is in focus.

CameraSize comparison with lens

A compositional feature of focal length is the way it alters perception of depth. Short focal lengths make objects look farther apart whilst longer lengths compress distances and make objects seem much closer together. Therefore, a wide-angle lens makes backgrounds seem far away whilst a telephoto lens brings them much closer.

Focal length

Focal length influences how your camera records a scene. It determines the angle of view, or how much of the scene ends up projected on the camera sensor. It controls how magnified an image looks, it influences the depth of field and can alter perspective, making objects look closer together or farther apart.

Focal length is a technical characteristic of a lens, related to the way it works, rather than its actual size. You can experiment with focal length in your photography to change perspective, play with depth of field and zoom in / out on your subject.
