Drop an X3F RAW file from your Sigma dp3 Merrill to check the shutter count — processed entirely in your browser, never uploaded anywhere. The dp3 Merrill is the telephoto-macro member of the Merrill trio, with a 50mm f/2.8 lens (75mm equivalent) and a 1:3 macro ratio, using the same symmetric Foveon X3 Merrill APS-C sensor (~46 MP effective) as the dp1 and dp2 Merrill.
Check Shutter Count →The Sigma dp3 Merrill (2013) is the third and final model in Sigma's dp Merrill compact series. Its fixed 50mm f/2.8 Macro lens delivers a 75mm equivalent perspective with a minimum focusing distance of 22.6 cm and 1:3 magnification — the only dedicated macro model among the three Merrill compacts. It shares the Foveon X3 Merrill APS-C sensor (approximately 46 MP effective) with the dp1 and dp2 Merrill, released one year earlier. Sigma does not publish an official shutter life rating.
| Model | Release | Lens | Sensor | Est. Shutter Life |
|---|---|---|---|---|
| Sigma dp3 Merrill | 2013 | 50mm f/2.8 Macro (75mm equiv.) | Foveon X3 Merrill (~46 MP) | ~100,000 (est.) |
| Sigma dp2 Merrill | 2012 | 30mm f/2.8 (45mm equiv.) | Foveon X3 Merrill (~46 MP) | ~100,000 (est.) |
| Sigma dp1 Merrill | 2012 | 19mm f/2.8 (28mm equiv.) | Foveon X3 Merrill (~46 MP) | ~100,000 (est.) |
| Actuation Count | % of Est. Life | Assessment |
|---|---|---|
| 0 – 3,000 | 0 – 3 % | Very low use — near new |
| 3,000 – 20,000 | 3 – 20 % | Low to moderate use |
| 20,000 – 55,000 | 20 – 55 % | Moderate use — normal for active shooting |
| 55,000 – 85,000 | 55 – 85 % | High use — negotiate price |
| 85,000 + | 85 %+ | Near or past estimated life |
The dp3 Merrill's macro capability encourages even more deliberate, low-volume shooting than the wider Merrill models. Most examples have under 5,000–8,000 actuations despite being over a decade old. When evaluating a used dp3 Merrill, also check lens clarity at close focus distances (any internal dust or mould is more visible at macro range) and autofocus hunting at minimum distance.
The 50mm f/2.8 lens on the dp3 Merrill achieves a 1:3 reproduction ratio at its minimum focusing distance of 22.6 cm. This is genuine macro capability, not a close-focus mode: at maximum magnification, the Foveon X3 Merrill sensor renders subject detail at approximately 46 MP effective resolution, which is exceptional for fine-textured close-up subjects.
At minimum focus distance and f/2.8, depth of field is extremely shallow. For close-up work at maximum magnification, stopping down to f/5.6–f/8 is typical to achieve workable depth of field while maintaining Foveon sharpness. Note that at close-focus distances, autofocus speed decreases noticeably — manual focus assistance via the magnified view is often more reliable.
Yes. Drop the X3F file from your dp3 Merrill into shuttercount.app and the actuation count is displayed immediately.
The dp3 Merrill achieves a 1:3 reproduction ratio at its minimum focus distance of 22.6 cm. This means an object 27 mm wide fills the full frame width. For 1:1 macro, an extension tube or close-up lens would be needed, though modifying the fixed-lens dp3 Merrill for this is not standard practice.
Both cameras cover the 75mm equivalent focal length with f/2.8, but the dp3 Quattro (2015) uses the asymmetric Foveon X3 Quattro sensor (~29 MP effective) and has a significantly faster write speed (~10 seconds vs ~15–20 seconds for the Merrill). The dp3 Merrill's symmetric three-layer sensor theoretically captures more colour information at base ISO. Both are excellent for portrait and close-up work in controlled lighting.
Yes. The dp3 Merrill uses a mechanical leaf shutter in the lens barrel. Every still photo increments the mechanical shutter counter. There is no electronic shutter mode.
