Abstract
The invention discloses a lens. The lens comprises a lens body (1) and an armor (2), and is characterized in that the armor (2) is arranged on the lens body (1), and the lens body (1) is composed of a lens hood (3), a focusing gear ring (4), a middle section protection ring (5) and an aperture gear ring (6). Due to the fact that the armor is arranged on the lens body, the lens has the advantages that the size is uniform, shooting efficiency is improved, faults are reduced, and shooting cost is reduced.
Description
Technical field
The present invention relates to a kind of for the camera lens on photographing.
Background technology
Existing photography camera lens is because of focal length difference, and apparent size all differs, also different to the length of defocused extension, needs to readjust, cause inconvenience for shooting after upper spider.
Originally often change a camera lens when taking and just need spend the position and fuselage positions that within 20 to 30 minutes, adjust shading bucket, because the size of each camera lens is different, also need the center of gravity readjusting video camera, careless slightlyly just have light leak, during focusing, camera lens bumps against shading bucket, or occur with the phenomenon of burnt device slippage or shock, cause inconvenience during operation.And the preservation after using is also because size difference needs the anti-collision box using sizes, causes the inconvenience of carrying with depositing.
Summary of the invention
Technical matters to be solved by this invention is to provide one and has uniform sizes, improves shooting efficiency, avoids error, reduces the camera lens of the advantages such as shooting cost.
For solving the problems of the technologies described above, the invention provides a kind of camera lens, comprising camera lens, plate armour, it is characterized in that: described camera lens is provided with plate armour, described camera lens is made up of light shield, focusing ring gear, stage casing protection ring, aperture ring gear.
Further, described plate armour can according to the camera lens respective production of different size.
Further, described plate armour is made of plastics.
Further, described plate armour carries driving cog.
Compared with prior art, beneficial effect of the present invention is:
1: the uniform specification after plate armour loaded onto by camera lens.
2: do not have the phenomenon extended or shorten during focusing and occur.
3: loading onto the camera lens after plate armour can have better linking with shading bucket with burnt device.
4: plate armour carries driving cog, need at use extraneous gears.
5: the center of gravity must not readjusting video camera when changing camera lens again.
6: uniform sizes, improve efficiency during shooting, avoid error, reduce shooting cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of camera lens of the present invention.
Fig. 2 is that the present invention loads onto armoring rear overall structural representation.
Fig. 3 is the structural representation of plate armour of the present invention.
Number in the figure:
1-camera lens, 2-armoring 3-light shield
4-focusing ring gear 5-stage casing protection ring 6-aperture ring gear.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
Shown in Figure 1; a kind of camera lens; comprise camera lens 1, armoring 2; described camera lens 1 is provided with armoring 2; described camera lens 1 is made up of light shield 3, focusing ring gear 4, stage casing protection ring 5, aperture ring gear 6; described armoring 2 can according to the camera lens respective production of different size, and described armoring 2 are made of plastics, and carry driving cog on described armoring 2.
During fabrication and installation: measuring first by all precision size after the apparent size of camera lens and zoom, the diameter of camera lens is redefined in the aperture according to shading bucket, get maximin according to existing camera lens and calculate the compatible size of energy, develop apparent size unified, the plate armour that during focusing, overall length can not extend or shorten, is fixed on plate armour on existing camera lens in the mode of non-demolition formula afterwards.
In sum, the present invention is owing to changing camera lens because not needing to readjust shading bucket and fuselage distance when armoring shooting is housed on camera lens, operation only needs 3-5 minute, do not need because single Lens is different and do multinomial test, the phenomenon worrying burnt device slippage or shock is not needed to occur during zoom yet, focusing stroke is longer because external diameter increases stroke, focus more accurate, improve efficiency during operation, also reduce service time and the cost in film studio, use rear because of uniform specification, deposit and also become easy, the Portable box of standard only need be used when carrying, protection is provided to original camera lens, also reduce time and the cost of maintenance.
The foregoing is only better embodiment of the present invention; protection scope of the present invention is not limited with above-mentioned embodiment; in every case those of ordinary skill in the art modify or change according to the equivalence that disclosed content is done, and all should include in the protection domain recorded in claims.
Claims (4)
