There is a loss of light simply by virtue of the crop. You're using less of the sensor so you are capturing less light.All it does is crop from the full image, so there wouldn't be any loss of light. It's definitely a handy feature to have in camera (increased magnification etc.), but nothing you can't easily do in post with the same exact result.There is one feature that I think the 40mp allows that could be quite awesome. Per the review here- https://www.imaging-resource.com/PRODS/fuji-x-h2/fuji-x-h2A.HTM
"In addition to the standard 40MP still shooting mode, the X-H2 has a handy built-in "digital teleconverter" option thanks to its higher-resolution sensor. Users can enable a "1.4x" or "2.0x" teleconverter mode, which crops in on the sensor, but allows for some easy additional telephoto reach on your image without adding physical teleconverters to the end of your lens."
If there is no loss of light on the digital converter, does that mean you still get a 28mp image (40mp/1.4 converter = 28mp?) without a loss of light gathering since it's in camera? That makes every prime lens a dual threat and still with a resolution bump over the 26mp generation. I think I'm doing my math right? Haven't seen anything about losing light gathering ability with it. Does that make something like the 16-55 a 34-115mm lens? (1.5 crop of aps-c plus 1.4 digital teleconverter)?
Maybe I'm not interpreting that right- but a very intriguing feature.
At 1.4x crop you lose half the light, or one stop. At 2x crop you lose half again, or a total of 75% of the original, or two stops.
The net result is exactly the same as using a smaller sensor, and all that implies.
