Sony RX1R Review - The Sony RX1R loses an optical low-pass filter, but what does this mean for serious photographers?
Sony RX1R Review
The new Sony RX1R is essentially exactly the same camera as the RX1, with just one key change – it has no anti-aliasing filter over its sensor. These filters are designed to slightly blur the image reaching the sensor. With no anti-aliasing filter on the RX1R images should be sharper and more detailed than those from the standard RX1. However, with no anti-aliasing filter the risk of moiré patterning being introduced is a possibility.
Moiré patterning occurs when two linear grids are overlapped out of alignment with each other. It can be commonly seen when grid mesh of net curtains overlaps, creating a new concentric pattern to appear. The same thing occurs when the grid array of a digital camera sensor photographs a similar linear pattern, such as a tightly woven fabric, or intricate brickwork on a building, but we’ll cover more on this later.
Interestingly, the Sony RX1R will cost exactly the same as the standard RX1. This is significant as we’ve seen other manufacturers charge a slight premium for versions of their cameras without an anti-aliasing filter. Given that the RX1 costs £2,600, the fact that there will be no premium to be paid for the new model is a blessing, the RX1 costs enough already.
