I’ve used the pre-R Leicaflex and Leicaflex SL cameras pretty extensively and, apart from dud meters, found them to be exceptionally reliable. Of course, if the meters had worked, they’ll be inaccurate as the correct Mercury Oxide cell hasn’t been available for 30? Years. The later, Leica R8 and it’s updated R9 are Leica designed and built. I now use three of these bodies and find them a delight to use.
Now the Nikon D1X, I bought one a few years ago. A long way from Leica M3 and Leicaflex. A chap in a photographic shop in town where I went for a memory card, said he had used the D1X extensively in the past as a wedding photographer. He set up my camera to use as a point and shoot. Switch on and it’s set toMatrix metering and Program. Very easy. I can review and delete if necessary, I can find mono if I want. I’ve now got a lens with an aperture ring and can set this and change the camera to aperture priority. I have acquired a manual. Found flash a bit confusing but it seems dedicated units are required.
So, on the whole, I don’t find that the D1X is more complicated to use than the R8 as I use Program and Matrix metering for both.
