I'm trying to decide between the
Sony RX 100 mark 3
Canon G1x mark 2
Panasonic Lx100
Which one is the best at producing images with the lowest noise while capturing the most detail (not washed out)? And I tend to prefer a deep DOF.
All of these are going to produce good images.
You don't add "smallest" as a requirement.
- The LX100 *should* produce "lowest noise" due to largest sensor.
- The RX100 *might* produce "most detail" due to more megapixels.
- To be clear, deep DOF means you care about everything in focus... you don't care about a shallow DOF. If you want the deepest DOF possible, the smaller sensored Canon and Sony should provide that. However, if you use the LX100 to good effect, you should be able to recreate a deep DOF. Personally, I'd take the LX100 because it can create a deep DOF, but also a much shallower DOF than the other two can provide (when you want it.)
When you listed the three cameras, I immediately chose the LX100 -- but that's for me.
The LX100 will have the "best" overall photo quality with most flexibility. But... it loses out on resolution to the Sony and overall focal length to the Canon.
For your criteria, I'd be looking at the LX100 or the Sony.
Honestly, you're not going to go wrong with any of them.
