Interesting Fujifilm View Finder Patent Found
A reader despatched me an attention-grabbing patent that I did my finest to translate. It seems to be like Fujifilm is engaged on making a extra compact larger magnification viewfinder that works with LCD’s.  It was filed final month so it’s going to most likely be some time till we see it in a manufacturing product, however you possibly can learn extra about it under if you happen to prefer to learn translated patents.

From Translated Patent:
The current invention pertains to a finder optical system and an imaging equipment.

An eyepiece optical system is mounted on a viewfinder of an optical machine resembling a digital digicam. Conventional
As an eyepiece optical system, for instance, an optical system described in Patent Doc 1 under is understood. Patent Literature
The eyepiece optical system in keeping with No. 1 can be utilized for telescopes and binoculars, and features a diffractive optical aspect.
It’s configured utilizing. As well as, an eyepiece optical system configured utilizing a diffractive optical aspect and
Subsequently, optical programs described in Patent Doc 2 and Patent Doc three under are recognized. Patent Doc 2
The eyepiece optical system described in (1) can be utilized for binoculars, telescopes, and microscopes.

Subsequently, optical programs described in Patent Doc 2 and Patent Doc three under are recognized. Patent Doc 2
The eyepiece optical system described in (1) can be utilized for binoculars, telescopes, and microscopes.

In recent times, digital viewfinders (Elect.
Rical view finder) is usually used. Digital viewfinder
Is a show aspect resembling a liquid crystal panel for displaying a picture of the topic, and a picture displayed on the show aspect.
An eyepiece optical system is offered.

Nevertheless, the diploma of freedom within the configuration of the show aspect and the eyepiece optical system within the digital viewfinder is extraordinarily excessive.
Very low. When attempting to enhance the viewfinder magnification, that’s, to widen the viewing angle,
The variety of lenses constituting the eyepiece optical system will increase, making it tough to cut back the dimensions of the viewfinder unit.
The In the event you attempt to enhance the specs with out rising the variety of lenses,
It turns into tough to appropriate varied aberrations of the optical system.

When it comes to correction of assorted aberrations, the eyepiece optical programs described in Patent Doc 1 and Patent Doc 2 are each
Correction of astigmatism and distortion has been achieved to the extent required lately
It’s laborious to say. The eyepiece optical system described in Patent Doc three additionally has spherical aberration, astigmatism, and distortion.
It’s tough to say that aberration correction has been sufficiently achieved to the extent required lately.

In view of the above circumstances, the current invention might be suitably used for an digital viewfinder and the like.
Varied aberrations are corrected satisfactorily whereas lowering the angle of view, and the viewfinder unit is downsized.
Finder optical system that can be utilized, and imaging machine outfitted with the finder optical system
The aim is to do.
