Replacement Omega B22, B66 / C700 Negative Carrier


SKU: N/A Category:


A negative carrier for Omega B22, B66 and C700 enlargers. Specify the size and border variant of the specific one you are looking for. If the size you want is not available or you would like something custom, just let me know!

This carrier functions in much the same way as the original carriers though it lacks the spring mechanism, meaning it is best to adjust the negative before placing in the enlarger.

Border / Frame-Size Options

Standard – the opening is the standard size, either from the OEM or based on the measurements of the exposed area, to fully mask the negative
Bordered – the opening is a little larger than standard to expose part of the rebate of the negative. This is mostly for printing a black border around your image. Note this can impact flaring.
Full-Frame/Full Rebate – the opening goes all the way to the film edge exposing the entire rebate (including frame numbers and, for 35mm, sprockets). Due to potential flatness and flaring issues, this is best used when you want to specifically print the entire rebate.

The bordered and full-frame option may exhibit some vignetting or diminished performance for the 120 sizes, particularly 6×7, given the maximum size originally supported was a standard 6×7 frame.

These were designed by me and are printed on demand using Atomic PLA on my modified Prusa MK3s 3D printer. They should bring you years of reliable use when using them for normal printing sessions as long as they are stored reasonably. Store them with your lenses (e.g. not in an attic on a hot summer South Texas day shoved in an unnamed box to be forgotten about for 20 years). Clean with a damp cloth optionally with alcohol (do not use acetone).
