Micro Precision Products (MPP) MPP Monorail 4x5
The MPP Monorail 4x5 is a British-made large format camera taking 5x4 inch sheet film, produced by Micro Precision Products of Surrey. It uses a monorail design intended primarily for studio and technical work, with extended movements for perspective and focus control. MPP positioned its large format cameras as affordable domestic alternatives to imported Swiss and German equipment.
At recent UK auction, hammer prices for the MPP Monorail 4x5 have sat in a modest £65–£330 range, with a median around £88 — reflecting wholesale saleroom levels rather than dealer retail. In 2025 and early 2026 the camera typically sells for between £69 and £130 depending on completeness, so today the realistic value for a clean outfit with a working shutter and bellows is around £80–£130. Outliers at the top of the range tend to be lots bundled with lenses, film holders or a fitted case.

Frequently asked questions
What is an MPP Monorail 4x5 worth today?
Most examples sell for around £80–£130 at UK auction in 2026, with the median hammer price across recent sales sitting near £88.
How much does an MPP Monorail 4x5 sell for with a lens?
Outfits that include a working shutter-mounted lens and film holders have reached £170 and occasionally higher, while body-only or incomplete lots typically fetch £65–£90.
Why is the price range so wide?
The value is highly condition- and completeness-sensitive: bellows integrity, presence of a lens and lens board, and the number of double dark slides included each move the price materially.
Is the MPP Monorail a good buy for a first large format camera?
It is one of the cheaper routes into 5x4 shooting, but buyers should budget for potential bellows repair and for sourcing film holders, since these are often missing from auction lots.
