I had a second look, and I think I figured out why I prefer the 58/1.4G. It is they way the boys blend in with the background in a natural way. The 50/1.8S renders the boys in a way where they ...

Thanks Patrick for the side-by-side comparison. Like most people, including your wife, I prefer the 58/1.4G. I like the colors and the bokeh better. Are these JPGs out of camera or developed RAWs? ...

Wow, super informative post. I shall be honest, I didn’t really appreciate the grass-field test the first time I read about it, but this time it sank in. I’m now a fan of curved lenses and testing...

I haven't checked the numbers, but most likely, the largest effect is that a larger sensor requires a larger aperture (in millimeters) lens to give the same equivalent focal length. And it is the...

Hi Tom, I would attribute this to the computational photography in smart phones. It is amazing what it can accomplish with very little light. In weak light conditions, these cameras take multiple...

It is the amount if light that enters the lens (i.e. the aperture size) that determines the character of the image, e.g. the depth of field, the amount of noise due to the randomness of photons, so...

@paulsch The theory is right, but in the last paragraph you make the incorrect conclusion. It is the light projected from a given subject that matters, not the light per unit area of the detector....

The f/2 nomenclature referrers to the relative size of the aperture diameter relative to the focal length. It makes no sense to give one number i “equivalent”” units and not the other.

The f/2 is...

The aperture diameter of the Olympus is 25/1.2 = 20.8 mm and 50/1.2 = 41.7 mm for the Nikon. That gives an area of 340.9 vs 1363.5 mm2. So, the light gathering capability is 4 times more for the...

If this is the only reason (and not that they could not make it any smaller due to mechanical aperture control stuff), I’d almost prefered if they would release camera-specific adapterd of the ...
