Sony RX1R II

Ergonomics: Aperture Ring

Only one test sample was available, so it’s not clear if this applies to all samples, or just that this particular sample has an unusually stiff aperture ring: on the test sample, the aperture ring is among the stiffest I have ever used over many years of testing cameras. Considerable torque is required to change aperture. It is not at all like Zeiss Loxia or Zeiss ZM crispness and ease of changing aperture.

The aperture ring has minimal spacing between it and the near/far focus control ring. Worse, my thumb is wide enough to completely cover both the aperture ring and the near/far focus ring. Because the aperture ring is so close the camera, only half of my thumb falls naturally on the aperture ring; the other half of my thumb starts to cover the near/far focus control ring (yes, the thumb can be forcefully jammed against the camera body, and that helps, but doing so requires attention; it does not fall into place that way). Worse, the opposing finger tends to fall right onto the near/far focusing ring.
