Question 1

How do you inspect used cameras?

Accepted Answer

Every used camera goes through a 20-point check by our camera specialists. We check things like the operation of autofocus, image stabilisation and shutter; the shutter count; the condition of the sensor; the LCD screen for function and dead pixels; the viewfinder (optical or electronic); all buttons, dials and connections; the lens mount and contact points; and the cosmetic condition. Based on the inspection, every camera gets a transparent condition grade and at least 12 months warranty as standard.

Question 2

Which brands sell medium format cameras?

Accepted Answer

The main brands in medium format are Phase One, Hasselblad and Mamiya. On this platform, you'll mainly find used Phase One and Hasselblad systems — including matching digital backs — as well as Mamiya 645-compatible backs.

Question 3

What's the difference between a medium format camera and a full-frame camera?

Accepted Answer

A medium format sensor is physically larger than a full-frame (36×24 mm) sensor. This means more light capture per pixel, greater dynamic range and higher resolutions. Typical medium format sensors range from 44×33 mm up to 53.7×40.4 mm on the larger Phase One and Hasselblad backs.

Question 4

What's a digital back, and do I need one?

Accepted Answer

A digital back is the interchangeable sensor unit of a modular medium format system. You combine a back with a compatible body — for example, an IQ back on a Phase One XF, or a Phase One Credo 80 on a Mamiya 645. If you buy an integrated camera, you won't need a separate back.

Question 5

Are Phase One backs compatible with Hasselblad bodies?

Accepted Answer

That depends on the mount. Phase One backs come in various mount options: Phase One XF, Mamiya 645, Hasselblad H and V Mount. A back with 'Hasselblad H' in the name fits Hasselblad H-series bodies; a back with 'V Mount' fits Hasselblad V-system cameras. Always check the exact mount specification in the product description.

Question 6

What are the differences between the Phase One IQ1, IQ2 and IQ3 backs?

Accepted Answer

The IQ generations build on one another in terms of functionality and sensor performance. IQ1 backs are the first generation of the IQ line; most IQ1 variants use CCD sensors, but the IQ1 100MP uses a CMOS sensor instead. IQ2 backs add improvements to the screen and connectivity; the IQ2 100MP variant also uses a CMOS sensor, while lower-resolution IQ2 backs are CCD-based. IQ3 backs introduce a full CMOS sensor across the entire line, offering better high-ISO performance and live view. For studio work under controlled lighting conditions, CCD backs are still excellent; for location work, an IQ3 is more pleasant to use thanks to CMOS's improved ISO performance.

Question 7

Which medium format system is the best starting point for someone switching from full-frame?

Accepted Answer

A Phase One 645DF+ or Phase One XF body combined with a used digital back from the Credo or IQ series offers a professional foundation with maximum flexibility. The modular setup means you can later upgrade just the back if you want to improve resolution or sensor performance.
