Introduction
Sony’s latest iteration of its RX100 advanced compact,
the RX100 VI, boasts a 24-200mm f/2.8-4.5 lens in a body shape that’s nearly identical to its Mark V predecessor (which had a 24-70mm f/2.8 lens).
The RX100 VI’s lens features optical image stabilization good for up to four stops of correction, per CIPA standards.
The RX100 VI boasts a 20-megapixel 1-inch stacked CMOS sensor and can deliver up to 24 fps continuous shooting with autofocusing engaged. The camera can acquire focus in .03 seconds, making it the world’s fastest in its class, according to Sony.
Beyond the longer zoom lens, the Mark VI features improved eye AF tracking (2x better than the Mark V) plus touch focusing and touch shutter on its 3-inch display. The display can be tilted up 180 degrees or down 90 degrees.
There’s still a pop-up electronic viewfinder, but now the viewfinder can be sprung with the touch of a button (vs. pulling it up manually on the Mark V).
The camera has 315 AF points, 4K video recording with S-Log3/S-Gamut3 and a 1000 fps slow motion mode.
The RX100 VI is available now for $1,200.
Resolution
* Reaches 94 percent of the theoretical maximum of its 20-megapixel sensor at ISO 125 (1708 line pairs per picture height (LP/PH)).
* Resolution remains good as ISO increases (e.g. 1634 LP/PH, 90 percent of theoretical maximum at ISO 800) up to ISO 1600 (1591 LP/PH; 87 percent of theoretical maximum).
* The highest ISO s showed poorer resolution (e.g. 1336 LP/PH, 73 percent, at ISO 12800).
* The predecessor Mark V, which had the same range of ISO , produced images with 1691 LP/PH (93 percent) at ISO 125, and 1611 LP/PH (88 percent) at ISO 1600, and 1360 LP/PH (75 percent at ISO 12800).
This graph shows the loss of contrast (y-axis) as a function of the spatial frequency in line pairs per picture height (x-axis) for different ISO-sensitivities (colored lines). The further to the right a curve stretches before descending, the better the resolution at that ISO. The limiting resolution for each ISO can be found by identifying to the highest spatial frequency which results in a contrast of 0.1, or where the ISO curve crosses the thicker horizontal thicker...
