comment How can I ensure proper color rendition with browsers on wide gamut displays?
While the default is to only color-managed tagged images, Firefox can be configured to use color management for all images.

comment How do you find out the “sweet spot” of a lens?
Karel those calculators only factor sensor resolution because they make the assumption that the lens out-resolves the sensor. If you want to argue that the diffraction limit is the same for the Zeiss 100mm f/2 as it would be for for one of those 28-300mm lenses @ 100mm, we'll just have to agree to disagree.

comment How do you find out the “sweet spot” of a lens?
Karel, the point at which a lens becomes diffraction limited is absolutely a property of the lens, it has to do the resolving power of the lens. For instance the Zeiss 100mm f/2 Makro-Planar is sharpest at f/4, and only goes downhill from there (admittedly very gradually, and even today's 24mp cameras won't show the falloff until you go past f/5.6) You may not be able to see the true diffraction limit if the lens out-resolves the camera/sensor you're using, but that doesn't mean the limit isn't there. There's a reason high-end lens testing is done with an optical bench rather than a camera.
