Ricoh GXR: Corner Softness Samples A16 24-85 (after Repair - Part 2)

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

Archive

On this page, I compare corner softness of the A16 24-85 camera unit for the focal lengths of 24 mm, 28 mm, 70 mm, and 85 mm after an adjustment of the camera unit at the CONVAIR repair center in Pirmasens, Germany. On this page, there are also further samples with landscape and architectural scenes, however, without systematically varying focal length (no sections, only overviews and original files).

See also a second set of similar test shots without sun (and more focal lengths) and my page with samples taken with the replacement camera unit (added on October 14, 2012).

After the adjustment, things have somewhat improved. However, I still find some of the corners at 24mm and 28mm too fuzzy - but this is only my personal opinion...

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

Further Samples

Here, I provide some further sample photos that demonstrate corner fuzziness (or softness) with some landscape 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.
