Thank you to those who were able to respond. After a lot of deliberation, I have decided to go with a Sony A7R III and adapt my lenses using the Sigma MC-11, as I have some sigma art lenses and Tamron lenses. Depending on how well they work will determine on what, if any, Sony lenses I buy. My low light urban is long exposure using a tripod at iso 100.

I currently have an 80D and an RP, both of which have and continue to serve me well. I am now considering whether to upgrade to the R8 or get a second hand 5DS R. I am aware that the R8 has plenty of bells and whistles, but, I am more interested in image quality,. I have heard good things about the 5DS R and can obtain one with less than 10000 actuations. I mainly do landscape and low light urban photography.. The camera would be on a tripod shooting at iso 100. Can anyone who owns the 5DS R advise re noise and detail in low light images taken under the conditions outlined?

It seems that people are referring to filters that screw in /on to the lens. I see no mention of the likes of Lee or Cokin (European) square/rectangular filters with separate filter holder with adapters for the various lens sizes. Filters can be both resin or glass, with the glass usually being the better quality. I picked up a Cokin Nuances 10 stop ND filter for £50 or about $65. Haven't tried it out yet, but will do when I am on holiday in a few days. These systems can prove cheaper in the long run if you are going to be using more than one lens. The Cokin filter system comes in 'P', 'Z-pro' and 'X-pro' sizes depending on the size of the lens.
