In my post of about a week ago, I thanked Nikon for what I thought they did well on the Z-mount. Now I am going to describe what I would like to see next and why - ie. what are the benefits?
1: An image sensor that utilized more or all of the image circle. The current FX image sensor has an area of 864 square mm on a 36mm by 24mm sensor. The shortcomings are:
-If you want to shoot in portrait mode comfortably, you need to invest in an expensive battery grip with controls. For me, this is the main reason to buy a battery grip.
-If you want to shoot using a different aspect ratio, say 1:1, you can only use 576 square mm of the sensor (24mm by 24mm)
If you increase the size of the image sensor by 50% to 36mm by 36mm, the area would be 1,296 square mm. This would:
-Enable switching between portrait and landscape mode without physically rotating the camera 90 degrees.
-Use more area for different aspect ratios. For example, shooting 1:1 on the 46mp current sensor for the D850 will result in a 30.66mp image file. Shooting 1:1 on a 36mm by 36mm sensor (assume 30mm by 30mm as that is about as large as one can get in a 44mm diametre image circle without cutting off the corners) will yield a 47.9mp image file. This is equivalent to upgrading to medium format light.
Would a bigger sensor cost more? Sure. However, my battery grip for my D850 cost about $1,200 CAD after adding all of the doodads. So I would save the cost of the battery grip plus achieve the above benefits.
In a day or two I describe the next thing that I would like to see.
