Greetings from a GR IIIx Urban Edition user

[Rollo]

Hello, I bought a GR IIIx to augment professional work with Nikon and Fuji systems. I wanted something for long walks that I could fit in my pocket and had a great lens. I am amazed at the quality of the images this little camera makes. Better, IMO than the Fujifilm XV100 that I ended up selling.

I do have a problem though. Ricoh was of no help in investigating this. I find that there is a pink/red tonal shift at the outer edges of images taken in landscape format. I am attaching an image of the snow taken in daylight conditions and even lighting. Its a bit like vignetting, except it involves color and does not have the characteristic concave/barrel shape of exposure-related vignetting. Please look carefully because the effect is fairly subtle.

Note: the image has not been altered except for Lightroom's built in profile correction.

Anyone else see an effect like this?

Another example of red shift at the edges - particularly the left edge...

Follow up. I sent my GR IIIx to Precision Repair. They compared shots that I sent demonstrating the red shift at the extreme edges, with shots take with their "Master Camera". Both showed an equal amount of red shift. Conclusion: the red shift is intrinsic to the camera design. One site said that it was due to the angle of light at the edge of the lens hitting a sensor that is extremely close to the lens. Therefore there is nothing to be done. I would argue that Ricoh should have recognized the issue and created a correction and/or mask that would compensate for the color distortion.

Hi Rollo,
I don‘t want to say, that the tonal shift is not existing and I take your problem absolutely serious. Only I am surprised how different people see pictures, because when I look at your examples, I can not see it. I have a GRIIIx as well and never recognized this effect. I hope you enjoy your GR despite it.

Its probably because I do a lot of color correction for professional work. If you don't see it, you are lucky. And I definitely still like the camera - nothing else is pocketable yet still makes really high quality images.
