Fun with the Ricoh GR III

A few test shots with the wide angle adapter GA-1 on the GRIII. It gives an angle of view of 21mm in full frame equivalent. In general it is nice and sharp in the centre with only a small drop off in sharpness in the corners. It does introduce some colour fringing of objects against bright backgrounds and a small amount of barrel distortion - neither of which are that noticeable.

This first one specifically had the fringing on the overhead rail cross members against the sky and also some barrel distortion on the window frame close to the right edge. I am currently trialling DxO PureRAW2 and it removed both problems.

Conversely, this frame did not seem to exhibit either problem but it could be in the vertical barrel distortion is less noticeable. Or I was just lucky. I converted it to monochrome in DxO Silver Efex.

Finally, this is a common test shot for me, the horse bridge over Hampstead Lock in Camden, London, England. Again, I did not feel it needed any corrections, only processing.

One question in between pictures: Does anyone use the Nisi filter kit for the GRD and is it worth it? Thank you!
