HARMAN technology TiTAN 4 x 5" Pinhole Camera

The HARMAN technology TiTAN 4 x 5" Pinhole Camera has a 72mm focal length with a 97° angle of view, which would be roughly equivalent to a 20mm lens used on a full-frame 35mm camera. This would be right near the beginning of the focal lengths considered as a super-wide angle lens.

Unfortunately, there is not a viewfinder specifically designed for use with this camera, or for cameras with a 5:4 film aspect ratio. Most of the optical viewfinders we carry are designed for use with the 35mm 3:2 aspect ratio. However, if you are looking for an optical option that may work for your needs, while it would not exactly cover the frame on the long ends due to the aspect ratio difference, the Ricoh GV-1 External Viewfinder B&H # RIGV1, the Sigma VF-31 External Optical Viewfinder, B&H # SIVF31, and the Zeiss ZI Viewfinder for Zeiss Ikon Camera When Used with 18mm ZM Lens, B&H # ZEVF18, would have the closest angle of view for use with the Ilford HARMAN TiTAN 4 x 5 Pinhole Camera.

We no longer sell the cones on their own.

i'm sure you could but I don't know that it would be all that helpful.

If by "medium format back" you mean a roll film back that uses 120 roll film on a 4x5 camera then yes. I've used the Horseman 6x9 and 6x12 backs on the Harman Titan without issues.

Unfortunately, the Lomograflok Back is not compatible with the TiTAN 4 x 5 Pinhole Camera.

I just had a thought....the 2 white screws that you are speaking of are probably the fastener to attach the paper calculator to. The white screws are not for the camera directly.

No it does not. I just bought this kit and it comes with the camera and the paper exposure calculator. You will need to buy a 4x5 film holder and 4x5 film (or 4x5 direct positive paper) to use this camera. (The older version of this kit did include film but that version is no longer available.)
