Abstract
The invention discloses a multiple focal length variation range modularization combined telephoto lens system, which comprises a photographic lens, a first focal length transfer environment module, a second focal length transfer environment module and a third focal length transfer environment module, wherein the first focal length transfer environment module, the second focal length transfer environment module and the third focal length transfer environment module are in bayonet connection with the photographic lens respectively to form changeable telephoto lenses. The system has the following advantages: through the telephoto lenses formed by matching the different focal length transfer environment modules and the photographic lens and differing little in the entrance pupil diameters, the one photographic lens can be used in common; through the connection of the photographic lens and the transfer environment modules of different focal lengths and the coordination with a single-lens reflex camera, the long focal length photography system with the different focal lengths can be formed; through the combination of the different modules, a long focal length photography system with one photographic lens and three focal lengths can be realized, thereby conveniently satisfying the requirement of the amateur photographer on achieving the satisfactory lens focal length without the need of costing much.
Description
[technical field]
The present invention relates to a kind of telephoto lens; Be specially a kind of telephoto lens system of how burnt root module combination; Be adapted to pass through the telephoto lens of the different long-focus sections of constituting of module, and can connecting the long burnt camera chain of formation slr camera on these focal length adapter ring module basis.
[background technology]
Numerous phtographic lens manufacturers has released the telephoto lens that focuses of different focal section now; Such as focal distance f 300 aperture F4, focal distance f 400 aperture F5.6 and the isoparametric camera lens of focal distance f 800 aperture F6 are arranged respectively; The optical texture of this type camera lens mainly carries out complicated extending out in various degree to positive light coke group and negative power group on original telephoto objective architecture basics, the focusing mode all is that a certain set of contact lenses of taking to move in the light path system is carried out the constant interior focusing mode of tube length.Yet the flange of each producer's slr camera is apart from being different, therefore still will be according to flange apart from deciding adaptive slr camera with the camera lens of focal length and aperture, perhaps could match other camera through the bayonet socket adapter ring, and using is inconvenience extremely.
Telescope on the market can easily provide the visual observation of looking in the distance for people, but wants can only pull down eyepiece taking through slr camera fine a moment, connects photography switching optical system then, after alleviating the serious curvature of field and distorting, just is fit to photography.Perhaps, adopt the card camera to take, but annulus can occur in the visual field, and the signal noise of ordinary digital camera can't let the user obtain satisfied image effect directly through connecting support.
[summary of the invention]
The objective of the invention is to deficiency to the above prior art existence; A kind of telephoto lens system of how burnt root module combination is provided; The telephoto lens that a photographic lens is realized multiple focal length that constitutes through different focal adapter ring module; And connecting the long burnt camera chain of cooperation slr camera formation on these focal length adapter ring module basis, when satisfying, alleviated buyer's body burden and financial burden again to the different focal needs.
For achieving the above object; Technical scheme of the present invention is: a kind of telephoto lens system of how burnt root module combination; Comprise a photographic lens and a minimum focal length adapter ring module; Said focal length adapter ring module and photographic lens connect to form telephoto lens with the bayonet socket mode, and said focal length adapter ring module connects to form camera chain with bayonet socket mode and slr camera again.
Said focal length adapter ring module comprises the first focal length adapter ring module, the second focal length adapter ring module and the 3rd focal length adapter ring module, and the said first focal length adapter ring module, the second focal length adapter ring module and the 3rd focal length adapter ring module connect to form switchable telephoto lens with photographic lens with the bayonet socket mode respectively.
The said first focal length adapter ring module, the second focal length adapter ring module or the 3rd focal length adapter ring module comprise minimum one group of lens and adapter ring module base, and said lens are arranged in the said adapter ring module base.
Rear and front end in the said adapter ring module base is respectively arranged with and is used for the bayonet socket ring that is connected with said photographic lens and slr camera.
The said first focal length adapter ring module, the second focal length adapter ring module and the 3rd focal length adapter ring mould are respectively f300 focal length adapter ring module, f400 focal length adapter ring module and f600 focal length adapter ring module.
Said photographic lens is combined with the 77mm filter glass.
The present invention can be provided with the burnt phtographic lens of length of different focal adapter ring module and photographic lens formation, is connected with different focal adapter ring module through photographic lens, and then is connected with slr camera, just can be combined into the burnt camera chain of the length with different focal.Just can realize the telephoto lens of three kinds of focal lengths through the combination of different focal adapter ring module, solve when not needing expensive cost, the got back problem of telephoto lens of three kinds of focal lengths of a photographic lens of shutterbugs greatly.
Compared with prior art; The present invention has following advantage: the telephoto lens that matches with photographic lens and constitute through different focal adapter ring module; The shared photographic lens of ability under the situation that the entrance pupil diameter is more or less the same; Be connected with the adapter ring module of different focal through photographic lens, and then cooperate slr camera, just can be combined into the burnt camera chain of length of different focal.Just can realize the burnt camera chain of length of three kinds of focal lengths of a photographic lens through the combination of disparate modules, satisfy shutterbugs easily and do not satisfied demand again in the expensive cost of needs lens focus.

[embodiment]
Below in conjunction with accompanying drawing and specific embodiment the present invention is carried out detailed explanation.
A kind of telephoto lens system of how burnt root module combination; As shown in Figure 1; Comprise photographic lens 1, the first focal length adapter ring module 2, the second focal length adapter ring module 3 and the 3rd focal length adapter ring module 4, the said first focal length adapter ring module 2, the second focal length adapter ring module 3 and the 3rd focal length adapter ring module 4 connect to form switchable telephoto lens with photographic lens 1 with the bayonet socket mode respectively.The said first focal length adapter ring module 2, the second focal length adapter ring module 3 and the 3rd focal length adapter ring module 4 connect to form camera chain with bayonet socket mode and slr camera 5 again.
Said first focal length adapter ring module 2 and the 3rd focal length adapter ring module 4 comprise minimum one group of lens and adapter ring module base, and said lens are arranged in the said adapter ring module base.As shown in Figure 5, the rear and front end in the said adapter ring module base is respectively arranged with and is used for the bayonet socket ring 7 that is connected with said photographic lens 1 and slr camera 5.
