LS55 Page Banner


Coming for 2017!

We are working on a "4x5 - 5x4 inch digital back". But it will actually be a 5x5 inch square format.

It is hip to be square

Having a square back will be nice as you don't need to rotate it, and quite a few people like the square format. A cropping option will allow you to crop to 4x5 or 5x4.

Use it like a film camera

All lenses with an image circle for 5x5 inches should work fine, even with lots of movements. Treat it like a monochrome film camera, with nearly unlimited film, and with the possibility to change the film type after shooting.

Being fat is lovely

People like to reminisce about medium format fat pixel digital backs. Fat pixels are sharp, have great tones and range. The LS55 pixels are beyond fat, they are humongous. Diffraction is not much of a worry with big pixels.

LS55: Expected USA price US$48,500

Infrared (IR) Support

Excellent support for IR and UV, since there is no blocking filter in the camera. 


  • 5x5 inch high sensitivity, large pixel digital sensor
  • 6.7 Mega Pixels - 6,760,000 pixels with high FWC
  • 50 micron pixel size (these are very large)
  • Live view for easy focusing
  • WiFi for remote viewing and control
  • 1300 × 1300 movie mode with an optional 1280 x 720 crop. Up to 26 fps. Video output options TIFFs, DNGs, CinemaDNG, JPEGs, h.264
  • 14 bit AD; 16 bit files
  • No CFA, no AA and no micro lenses. This allows large movements without affecting edge image quality.
  • Output to DNG, TIFF and JPEG.
  • Media: CF and SD card slots.
  • Tethered operation, by CAT5 cable or WiFi.
  • Dust - The sensor is large and can pick up dust. It is easy to remove the bellows and clean the sensor. Also a white frame can be taken before a photo session which works very well in removing most dust. The white frame is incorporated into the camera software.
  • All specifications subject to change

Suggested accessories:

  • Tablet or notebook for camera control and FFC
  • IR & UV blocking filters for your lenses for outside photography and for hot lights. Flash photography does not typically need the filters. 
  • ND filters for shooting wide open since the digital sensor is much more senestive than film
  • A sturdy tripod. 
  • Sensor cleaning tools. We recommend Eclipse fluid, PEC pads and a Giottos Rocket Blaster Dust-Removal blower. There is an external glass in front of the sensor glass so that if you damage the glass it can be replaced.

Mounting the LS55

8x10 cameras are the best option for the 5x5 inch LS55 digital back to allow full coverage.

Planned Compatibility at Launch

FIELD CAMERAS Svedovsky 8×10D will be fully compatible with a custom mounting plate. It should be ready by the camera launch. The cameras are affordable, solid and good looking. The camera will have a custom modification by Svedovsky to handle the additional weight of the digital sensor compared to film.

Colors available: natural wood, red mahogany and black

Sinar P1, P2 and Sinar Norma: If parts are available the 8x10 Sinar system should allow mounting of the LS55 digital back.

Extra Mounting Options

Many people have expressed strong interest in mounting the LS55 on their own 4x5 camera. There are issues with it, such as possible cropping of the sensor, weight and infinity focusing. Though, we'll give it a try. Most likely a back for the camera, such as a film back, would be needed to construct a mount from.

How to buy the LS55

You may join our LS55 Interest List and our mailing list and we will update you when we're ready for taking orders. It expected that the camera should be ready for sale in the middle of 2017. For those who wish to demo the camera we will offer those by appointment in Santa Clara, CA, USA.



LS55-M Monochrome 5x5 inch digital camera

LS55-C Color 5x5 inch digital camera - Available after the monochrome version if there is enough demand.

C - color
M - monochrome

Front Sensor Glass

The sensor has glass bonded to it. In front of that glass is another plate of glass which protects the sensor glass, called the Front Sensor Glass. The front sensor glass can be configured for visible light only, or to allow all light.

During ordering the type of glass can be picked. Afterwards the glass can be changed but requires disassembly of the camera.

LS55-Glass-FB  Full band. Allows taking NIR or UV images. Requires filters.

LS55-Glass-VB  Visible band pass. Blocks NIR and UV, allowing only visible light. The advantage is that every lens is ready without needing a filter.


A Portable Solution

The LS55 and Svedovsk 8x10D camera, along with accessories will fit into a large backpack, making it a portable large format digital solution.

STATUS: June 2017

A prototype 5x5 sensor should be with us by Sept. or Oct. 2017 and a digital back prototype will quickly follow. Then production units.
