I was today in one of the camera stores of "big camera" in Tokyo close to Ginza station. They have a huge choice of all brands there. You can grab and test every model.
Olympus, Panasonic, Nikon, Canon, Sony and even Pentax etc.
So, I took all the different models in my hand to see which one feels good in my hands. It turned out that the Lumix S5ii and the old Olympus EM1 Mkiii are the most comfortable bodies in my hand. The new Nikon Z6iii and all others were very uncomfortable for my hands.
I think this is an often overseen buying decision factor. Most users look on the technical data on the spec sheets and in youtube reviews, buy a camera and sell it 6 months later, because it is a nightmare to carry it around.
I had the original Nikon Z6 (mki) and liked the body. But what Nikon made now with the Nikon Z6 mkiii, the Z8 and Z9 is ridicilous. Bigger is not better. Similar with other brands. Unfortunately the Lumix G9 mkii disappointed me too.
Fuji X system was the only one, which offered bodies in the right sizes. No wonder that they increased their market share so strongly over the last couple of years.
I hope that Panasonic made the right decision for the not yet known L-Mount and MFT bodies.
It seems that the whole industry (incl. OM System with its OM1) is making each body only bigger, thicker and less comfortable to hold in the hand for more than 10 minutes.
I would rather buy then a second hand model with inferior AF or image quality as long as it is smaller, lighter and better to hold for a few hours thanks to better shaped grips and bodies.
With these new "bricks", you will never attract a smartphone user for an MFT or full frame system. Fullframe which feels like Medium Format and MFT which feels like fullframe. What are they thinking?
