The Need is presented in an advertisement by Eikōdō, published at an unknown date. The camera is described as all-metal. The daimeishi model is listed in five versions, supplied with three plate holders and one film pack holder:
- double extension bellows, Vario shutter, Meyer f/4.5 lens, ¥35;
- double extension bellows, Vario shutter, Meyer f/6.3 lens, ¥30;
- single extension bellows, Vario shutter, Meyer f/4.5 lens, ¥30;
- single extension bellows, Vario shutter, Meyer f/6.3 lens, ¥23;
- simple Bulb and Instant shutter, simple lens, ¥15.
The pictured camera has a dial-set Vario and probably an f/4.5 lens. The body has simple incurved struts, a brilliant finder offset to the left and a wireframe finder with a rectangular eyepiece. It seems that there is a focusing worm-screw on the photographer's right and a distance scale on the left, and the front standard perhaps allows vertical movements.
In the same advertisement, the atom model is called Model A (A號), and is offered with a simple Bulb and Instant shutter and a simple lens only, at ¥8.50, including six plate holders. In the picture, the camera body looks like a down-sized version of the daimeishi model. No focusing control is visible, and the camera is perhaps focused by moving the lens standard back and forth by hand. There is a brilliant finder but no wireframe finder, and it seems that no movement is available. The shutter plate has the name NEED inscribed at the top.
The only known surviving example is pictured in Sugiyama. It is in daimeishi format, has a small focusing wheel on the photographer's right, a brilliant finder and a wireframe finder (whose front frame is missing), and no movement ability. The shutter is a dial-set Elka, giving 25, 50, 100, B, T speeds, and the lens is reported as a Steinheil Anastigmat Trionar 105mm f/6.3.
Yazawa shows a Fuji Optische Werk Anastigmat Trionar 105mm f/6.3 and Elka-C shutter (10–150, B, T), reportedly coming from a Need. The shutter plate has ELKA–C at the bottom, Patent–Pending at the top and a TB logo on the right. The name "Fuji Optische Werk" certainly corresponds to Fuji Kōgaku, which maybe acquired the license of the Trionar lens to Steinheil, and maybe assembled the lenses from elements coming from Germany.
