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 at relatively close range using close focus but a good depth of scene from f/2 through f22. It assesses color correction, as well as peak performance using the fine details (ice crystals) to determine the optimal aperture. Bokeh is laso interesting in this near to far scene.
Includes images up to 24 megapixels as well as many large crops, all from f/2 through f/22.
RX1R II v1.0 firmware. Settings: Shading Comp = Off, Chro Aber Comp = Auto, Distortion Comp = Off, SteadyShot = off, LENR = Off, LPF Effect = Off, Pre-AF = Off, manual focus. 2-second self timer, uncompressed raw format.
