Dr. Ulrich Rohde: This is a nice well written story with excellent pictures, but the ending is open. I was/am quite familiar with the D 700, it produced reliably good results but this thought process leaves the reader hanging. I understand to stay with Nikon based on the lenses, but what will be the final decision from your viewpoint ?

I think your posted pictures are excellent if not breathtaking. My analysis shows that the Nikon lenses seem to be better then the Canon, and my tests show that the Sony sensors are better then their lenses. Difficult decisions. For non sport pictures where image simply counts I like the Leica S007, but not easy to handle and pricey. For the sailing adventures the D 5 has been a terrific workhorse , with the Nikkor lenses.

I am very curious what you will end with !

On article The Leica Summaron 28mm F5.6 is old-fashioned fun (190 comments in total)

Dr. Ulrich Rohde: Indeed, this lens is fun to use. I took the 28/2 Leica Summicron at 5.6 to compare both and found a color shift . When using both in the US with the camera setting "sunny", the 28/5.6 lens Summaron produces better color reproduction, the Summicron is more yellow. But using AWB corrects this somewhat .

Technically correct, and I was referring to an observation without prejudice

Sorry for the confusion, yes I set the M 10 first to sunny and then to AWB, und both files went trough Lightroom 6.8 and then I looked at the resulting JPG.

In the USA the light temperate is more like 6500 deg K, so sunny may mean something different. I am not an expert in JPG generation , but noticed the color difference.

For me most of the pictures seem underexposed. Is this possible ?
