- GH5
- Metabones 0.64XL Speedbooster
- 20mm extention tube
- Canon 200/f1.8 L - camera reports f1.2 ?
The resized version, and Firefox really hurts the image, it is crushing the contrast range of light, oh, and bee is not in focus, shrug...
Camera is probably displaying f1.2 because of how well the Speedbooster works. Here's my math.
1.8 * 0.64 = 1.152.
Since aperture is calculated by fractions of the lens opening over the sensor size, you're actually getting better light gathering than F/1.2 lenses!

Lens aperture has absolutely NOTHING to do with sensor size.

FWIW red pepper flakes are pretty much always made from red chili peppers.

Due to the 'Lock down' we can only access walks near home. This is a view back to near where we live in Durham City.

I agree with you. While light transmission or T stops don't change with sensor size. The aperture setting or f number is calculated by diving the focal length by diameter of the aperture. This explains how iPhone camera assemblies are still much smaller than my 1.8 lenses stopped down.

Social distancing is certainly not a problem in your neck of the woods! I love the UK countryside.
