@Clayton1985 I do not see any evidence that Nikon's longer F-mount lenses are suffering due to using F-mount; Nikon has had considerable success with such lenses on its SLRs. Although the F mount...

jlabelle: Sony was only #1 in 36x24mm format for one half year period (and only in the USA); a half year when it had a new "entry-level" model (A7III) while the others did not and were instead...

I doubt that Olympus is going into 36x24mm format, either alone or with Panasonic; maybe it prefers to be strong in one format, where it is the market leader, and sees little potential from making...

The article notes that the Nikon Z lens road map has "nothing longer than 200mm, for now." And in fact it has only one lens longer than 85mm, the 70-200/2.8. My read is that Nikon expects...

Maybe not more than Panasonic, which has already announced an 8K global shutter sensor using a new approach that avoids the halving of full well capacity and one stop loss of DR that current ...

Agreed: f/16 is a fixed aperture ratio, not diameter (did anyone say otherwise?) All the scale is doing is indicating very roughly what aperture ratio one wold use in 35mm format with a lens of the...

@noisephotograper: good point: if so, then "f/16 blur simulation" is even more-so in the range of the "portrait" lens! Though I think it merges data from both cameras, so then the limits are less...

I buy my phones up-front (no contract) and keep them about four years—my iPhone 6S is not going away anytime soon. That way, even the most expensive phone would cost far less than what the mobile...

@ noisephotographer

1) Yes, the f/16 is the "zero" end of the scale for "how much added blur?"

2) I would guess that this feature is aimed at the "telephoto" or "portrait" lens, which is f/2.4,...

12MP is 4000x3000, and pixel pitch in the main "wide" camera is 1.4 microns, so the sensor is about 5.6x4.2mm, diagonal 7mm. I think that is what is called 1/2.55". It is about a 6x linear "format...

That f/1.4 to f/16 scale on the slider is explicitly about DOF ("bokeh") simulation.

That so-called aps-c sensor is 4:3 shaped (from pixel dimensions) so no use for any current still camera format. It is clearly for industrial video use,’and uses the older GS method that halves ...

Richard Butler: I’ve seen success in allowing an extensive lens system for a larger format to be used on a new smaller format, but I’ve not seen any evidence of a lot of people buying into—for...

EF-S lenses work on R mount because EF mount lenses do, and the only difference with EF-S lenses is that they might foul the mirror of an EF body — which is not an issue with an R body. So its a...

Richard Butler, your report of Canon thinking fits my guess, but which successful upgrade paths are you referring to?
I do not count the "downgrade path" of using lenses from a large existing 35mm...

That new EF-M lens suggests instead that Canon might plan on maintaining both systems, with the not-totally-crazy idea that different formats go with different lens systems and are best served by...

That 100mm is the effective aperture diameter; if the lens was a simple single lens element 200mm from the focal plane and the aperture diaphragm were right there, the aperture opening would be...

Not necessarily. A lens designed for R or Z mount could have rear elements at that 16-18mm distance from the sensor where the throat is and of diameter more than E mount's 46.1mm; anything up to ...

On the other hand, Canon’s detractors said that lack of full backward compatibility with all previous Canon lenses was a blunder, and Canon also did fine. In fact it overhauled Nikon to become the ...

EOS-M Mount is slightly wider than E mount (47 vs 46.1) and the same depth (18mm), so I can see no way that E mount serves 36x24mm format but EOS-M does not. That is, if EOS-M was a blunder for ...
