Start with the required magnification, then choose a macro lens that gives you consistent centre-to-corner detail and enough working room for your setup.

Choose by capture size, not focal length alone

A 1:1 macro lens is a practical starting point for most 35mm and 120 workflows on full-frame, APS-C and M43 cameras. It is not a universal requirement: a lower-magnification lens can still capture the entire film, with less sensor coverage. Small subjects such as a single half-frame image, or a larger medium-format sensor, may require more than 1x to make full use of the sensor.

Use the magnification calculator for your actual sensor and capture area before choosing a lens.

Practical lens starting points

These are starting points drawn from SuperStable's manual, not a ranking of every current lens. Manufacturer links verify mount and magnification specifications; performance should be checked at your actual reproduction ratio.

4433 and 5440 medium format

The Fujifilm GF120mmF4 Macro and Hasselblad XCD 3,5/120 Macro reach 0.5x without additional accessories. They can capture larger film, but 0.5x may not fill the sensor as efficiently as your calculated target, especially for 35mm.

For greater sensor coverage, consider a suitable adapted macro or reproduction lens. Verify the image circle at the intended magnification, not just the lens's nominal format. A full-frame lens adapted to GFX may vignette and require cropping; an adapter does not automatically increase coverage. Use the active cropped sensor dimensions in the calculator when crop mode is enabled.

Industrial reproduction lenses are an advanced option. Check the intended magnification range, sensor coverage, focusing hardware, aperture control and stray-light shielding before buying. A line-scan specification alone does not guarantee coverage or sharp corners on an area sensor.

Working distance and stand height

Shorter focal lengths generally need less camera-to-film distance at a given ratio. A 50-70mm macro can be useful when stand height is limited; a 90-105mm macro provides a different clearance and handling balance. Internal focusing means actual distances vary by lens.

For 8 x 10 film on a 78cm stand, consider a 50-60mm macro for single-shot framing, or a roughly 100mm macro with stitching. Check the actual lens and holder combination against the height guide; do not assume focal length alone guarantees clearance.

Before you commit

• Calculate the capture ratio, including any sprockets or edge markings you want to keep.
• Check the mount, adapter, active sensor coverage and physical clearance.
• Test centre and all four corners with flat film and careful alignment.
• For conventional macro lenses, compare f/4, f/5.6 and f/8 at the working ratio. Treat these as test points, not a universal optimum.
