What should you prioritise?
The three camera-and-lens routes below address different priorities for photographing stationary mineral specimens; none removes the need to check framing and keep a multi-frame setup stable.
Canon EOS R7 with RF 100mm F2.8L Macro IS USM
Consider it when: Raised specimens make in-camera focus bracketing and stacking useful, and you need the lens's stated 1.4x magnification. Canon UK specifies both features for these exact models.
Check before choosing: Confirm that a 100mm macro lens gives you workable framing and camera-to-specimen positioning on your table.
Nikon Z8 with NIKKOR Z MC 105mm f/2.8 VR S
Consider it when: Close inspection or substantial cropping makes the Z8's Nikon-stated 45.7MP native resolution useful alongside a 1:1 macro lens.
Allow for: Pixel Shift is a separate multi-frame workflow, not a substitute for focus stacking. Nikon Support lists subject movement, camera movement and changing brightness as unsuitable conditions for Pixel Shift.
Panasonic LUMIX G9II with LEICA DG MACRO-ELMARIT 45mm F2.8
Consider it when: You want to assess a smaller Micro Four Thirds setup and the lens's Panasonic-stated 1:1 magnification meets your close-up needs.
Check before choosing: Panasonic specifies 25.2MP for the G9II; decide whether that native resolution, the lens's framing and its working position suit your intended output.

What to check |
Who this matters to |
| Small-detail reproduction |
Check the exact lens's maximum magnification, mount and minimum focusing distance; relate its framing to your smallest specimen detail. |
If I need to inspect tiny inclusions or crop closely, the detail must occupy enough of the frame to be useful. Roughly 46% of consumers would put small-detail reproduction first. |
| Depth across a specimen |
Check whether the exact body offers focus bracketing, in-camera stacking or both, and plan for rigid support and consistent lighting. |
When a cluster has near and far faces, I do not want the important surfaces to fall outside one sharp plane; around 36% of consumers would prioritise depth across the specimen. |
| Tabletop practicality |
Compare the complete body-and-lens setup, including its focusing position and space needed for support and lighting. |
With little room to position equipment, I need a setup I can place and steady without crowding the specimen. Approximately 18% of consumers would make tabletop practicality their primary concern. |

Common questions
Is a mirrorless camera body alone enough for detailed mineral photographs?
Not when the detail you want requires greater close-up magnification than your chosen lens provides. Check a compatible macro lens's stated magnification and focusing distance: Canon UK specifies 1.4x for its RF 100mm macro, while Nikon UK and Panasonic specify 1:1 for the 105mm and 45mm lenses discussed here.
Does every mineral specimen need focus stacking?
No. Stacking is useful when one close-up frame cannot keep the important near and far surfaces sharp. Canon UK describes combining frames focused at different distances; test your intended camera's workflow with a stationary specimen and sturdy support.
Can image stabilisation replace a tripod for tabletop stacking?
Do not rely on it to keep a multi-frame setup aligned. Hold the camera and specimen steady and maintain consistent lighting; Nikon Support identifies camera movement, subject movement and brightness changes as unsuitable for Pixel Shift, which is distinct from focus stacking.
What should I check before choosing a camera for in-camera stacking?
Confirm what the exact model does: focus bracketing, combining the frames in-camera, or both. Check its firmware notes and lens compatibility rather than assuming that a similarly named camera offers the same workflow; Canon UK specifically documents in-built bracketing and stacking for the EOS R7.
What should I keep on record when buying camera equipment?
Keep the seller and purchase records, and check the seller's terms for change-of-mind returns and support. Those terms are separate from remedies for faulty, damaged or misdescribed goods; GOV.UK explains that consumer rights apply to goods bought remotely or in person.
