How the Hasselblad Extension Tube H26mm Works
Extension tubes work by physically moving the lens farther from the sensor, which shifts the focusing range and lets you get much closer to your subject. Because there are no glass elements inside, the Extension Tube H26mm adds zero optical distortion, chromatic aberration or any other lens artifact — the only thing changing is the minimum focus distance.
The H-series extension tubes retain full electronic communication between the lens and camera body. Autofocus keeps working, metering stays accurate, and EXIF data continues to be recorded. This is essential when shooting in a studio at medium format resolution and you need consistent, repeatable results.
The 26mm tube pairs effectively with the HC 2.8/80mm for portraiture and product macro work. You can also stack it with the H13mm extension tube to get 39mm of total extension for even higher magnification ratios. For dedicated close-up work, the HC 4/120 Macro is a natural lens companion, and adding the H26mm pushes it well into genuine macro territory.
Hasselblad has officially discontinued its H-system camera line, but the H-mount ecosystem — including HC lenses and accessories like this tube — continues to be widely used in professional studios. The Fujifilm GX645AF series is also fully compatible, which expands the pool of cameras you can use this tube with.
Use Cases for the Extension Tube H26mm
If you already shoot with an H-series Hasselblad body and want macro capability without spending on a dedicated macro lens, this extension tube is a cost-effective solution. Product photographers shooting jewellery, watches or textiles will find the extra magnification useful for detailed work at a fraction of the cost of a dedicated macro lens.
