Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of reflective ultrashort burnt zoom lens, including
Lens bodies 1, the outer right wall of the lens bodies 1 is provided with distance scale display screen 2, the distance scale display screen 2
Left side is provided with focusing ring 4, and the left side of the focusing ring 4 is provided with zoom ring 3, and the left side of the lens bodies 1 is provided with guarantor
Sheath mounting seat 5, the outer wall of the protective case mounting seat 5 is socketed with protective case 6, the inner chamber left side of the protective case mounting seat 5
