Sony RX1R II: Aperture Series from f/2 through f/8 (Creek Through Boulders, View From Above)

Get Sony RX1R II at B&H Photo. Strongly recommended: optional Sony LHP-1 lens hood to protect the front of the lens (and as a secondary consideration, stray light) as well as at least three Sony NP-BX1 batteries.

This aperture series studies the Sony RX1R II in detail, concentrating on sharpness

Sony RX1R II Aperture Series: Creek Through Boulders, View from Above

Includes images up to 24 megapixels as well as many large crops, all from f/2 through f/8.

I have some reservations about the Sony RX1R II: there is an instability in the RX1R II results which damaged several aperture series, with focus shifting to the background more and more at each aperture. At first I thought this was optical focus shift. But now it is seems that it is something with the camera—perhaps a mechanical issue, perhaps causes by a extremely stiff aperture ring which might somehow jiggle the focus of the lens? So the 2nd shoot is damaged too, the first one having suffered from autofocus error. I don’t understand the cause as yet, I just know that this camera is causing me a lot of frustration in delivering damaged sharpness.

RX1R II v1.0 firmware. Settings: Shading Comp = Off, Chro Aber Comp = Auto, Distortion Comp = Off, SteadyShot = off, LENR = Off, LPF Effect = Off. 2-second self timer, uncompressed raw format.
