Ricoh GXR: Corner Softness Samples A16 24-85

Corners 24 mm | Corners 28 mm | Corners 70 mm | Corners 85 mm | Further Samples

Archive

On this page, I compare corner softness of the Ricoh GXR A16 24-85 camera unit for the focal lengths of 24 mm, 28 mm, 70 mm, and 85 mm. I also provide a number of further samples with nature and architectural scenes, however, without systematically varying focal length (no sections, only overviews and original files).

I do not know, whether my unit is really decentered. At least, most corners are too fuzzy to my taste, and the fuzziness is unevenly distributed (which would speak for a decentered lens). Corner fuzziness does not seem to improve much when stopping down.

Note: I strongly recommend to download the original photos for a correct evaluation.

See also my sample pages (page 1, page 2) after an adjustment at the CONVAIR repair center in Pirmasens, Germany (added on June 3, 2012) and my page with samples of the replacement camera unit (added on October 14, 2012).

Further Samples

Here, I provide some further sample photos that demonstrate corner fuzziness (or softness) with various nature and architectural scenes, however, without systematically varying focal length (no sections, only overviews and original files). Usually, f-stop is as open as possible.

Note: The photos were taken specifically to demonstrate corner performance, particularly at the upper corners.
