Focal length equivalents & field of view#
Multiply any focal length by 3.93 to get the full-frame field of view. For fixed-lens cameras use the real focal length printed on the lens (e.g. “6.1–18.3 mm”), not the 35 mm equivalent.

Depth of field table#
Total depth of field at each subject distance, using a circle of confusion of 7.6 µm (the 0.030 mm full-frame standard scaled by the crop factor).

Equivalent aperture#
Exposure is identical at the same f-number on any format; equivalence only describes depth of field and total light.
Diffraction & pixel pitch#
With 2.70 µm pixels, diffraction starts to soften pixel-level detail around f/4.0. For maximum sharpness keep landscapes between f/2.8 and f/4; stopping down further trades detail for depth of field.
| Aperture | Airy disk diameter | Spread over | At 100% view |
|---|---|---|---|
| f/2.8 | 3.8 µm | 1.4 px | sharp |
| f/4 | 5.4 µm | 2.0 px | sharp |
| f/5.6 | 7.5 µm | 2.8 px | slight softening |
| f/8 | 10.7 µm | 4.0 px | visibly soft |
| f/11 | 14.8 µm | 5.5 px | visibly soft |
| f/16 | 21.5 µm | 8.0 px | visibly soft |
| f/22 | 29.5 µm | 11.0 px | visibly soft |
Maximum print sizes#
At 8 MP the Konica Minolta Dimage A2 produces 3,264 × 2,448 pixel images. See the 8 megapixel guide or the print size calculator.
| Resolution | Typical use | Inches | Centimetres |
|---|---|---|---|
| 300 DPI | Photo-lab quality | 10.9 × 8.2 in | 28 × 21 cm |
| 240 DPI | Fine-art inkjet | 13.6 × 10.2 in | 35 × 26 cm |
| 200 DPI | Wall print | 16.3 × 12.2 in | 41 × 31 cm |
| 150 DPI | Poster, viewed from 1 m+ | 21.8 × 16.3 in | 55 × 41 cm |
Night-sky exposure limits#
Longest exposure before stars trail. The NPF rule accounts for pixel pitch and is stricter than the classic 500 rule — use it for pin-sharp stars on high-resolution sensors.
| Focal length | 500 rule | NPF f/1.8 | NPF f/2.8 | NPF f/4 |
|---|---|---|---|---|
| 4 mm (16 mm eq.) | 31.8 s | 36.0 s | 44.7 s | 55.2 s |
| 5 mm (20 mm eq.) | 25.4 s | 28.8 s | 35.8 s | 44.2 s |
| 6 mm (24 mm eq.) | 21.2 s | 24.0 s | 29.8 s | 36.8 s |
| 9 mm (35 mm eq.) | 14.1 s | 16.0 s | 19.9 s | 24.5 s |
| 13 mm (51 mm eq.) | 9.8 s | 11.1 s | 13.8 s | 17.0 s |
Handheld shutter speed guide#
The reciprocal rule uses the equivalent focal length. High-resolution sensors may need one stop faster than this for pixel-sharp results.
| Focal length | No stabilisation (1/equiv. focal) | With 3-stop IS | With 5-stop IBIS |
|---|---|---|---|
| 6 mm | 1/25 s | 0.3 s | 1.3 s |
| 13 mm | 1/50 s | 1/6 s | 0.6 s |
| 25 mm | 1/100 s | 1/13 s | 0.3 s |
| 51 mm | 1/200 s | 1/25 s | 1/6 s |
Lens#
The Konica Minolta Dimage A2 has a built-in, non-interchangeable lens. Use the real focal length of that lens with the tables above; its full-frame equivalent is that number × 3.93.

Frequently asked questions#
What is the crop factor of the Konica Minolta Dimage A2?
The Konica Minolta Dimage A2 has a crop factor of 3.93× relative to 35 mm full frame (diagonal 11.0 mm vs 43.3 mm).
What size is the Konica Minolta Dimage A2 sensor?
8.8 × 6.6 mm (2/3"), an area of 58 mm² — 7% of full frame.
Is the Konica Minolta Dimage A2 full frame?
No — its sensor is 2/3", which is 14.9× smaller in area than full frame.
How many megapixels does the Konica Minolta Dimage A2 have?
