jjZ2, I was commenting on the comparison to APS-C, not to other 36x24mm format bodies — there is no weight saving for the A7C in that comparison. (And I would say that as more lenses are added to...

There are APS-C models like the Sony A6100 and A6600 at a substantially lower price while offering a rough match on features other than sensor size; that is one place that the smaller formats are...

I am pleased for the option of a smaller body, but there is no great challenge making a smallish _body_ with 36x24mm sensor, since the rear screen is far larger (about 45x60mm) and it is the room...

I won’t join the SLR vs EVF debate; I’ll just say that I hope Pentax succeeds in serving this niche, particularly as Canon and Nikon are likely to phase our SLRs once the market sector gets too...

Good point, panther fan: the main virtue of these new faster cards is that several hours of video do not take another several hours to read out to the computer. Sustained read speed might be the...

On the Samsung 500MP (or even 600MP: https://petapixel.com/2020/04/21/samsung-aims-to-make-600mp-camera-sensor-that-beats-the-human-eye/), that sounds goofy, for a reason you know: making a sensor...

@ilza: I wouldn't say complely useless, but certainly not a precise "brick-wall cutoff" measure that some seem to think it is! The rough rule of thumb I see based on experiments is that aperture...

No, the actual aperture ratio is what matters for diffraction and Airy disk diameter formulas, not any “35mm equivalent” as sometimes used for DOF comparisons.

That depends of the aperture ratio of the lens doesn't it? And it is not an abrupt yes/no thing, partly because the Airy disk is not a hard cut-off: the great majority of light falls closer to the...

they call it APS-C but it’s 20x20mm square and low DR of 64dB , a bit under 11 bits/stops; the price of its global shutter. It is for machine vision and such, not “normal” photography -- Smaller ...

One more on the theme of listen to the doctors more than the possibly self-interested politicians or ratings-driven...

I think I see our misunderstanding: you are looking at the recommendations for individuals in the normal situation, and that is mostly normal preventative measures, since there is no vaccination....

Medical sources are recommending more than that. They are also recommending social distancing (avoiding big crowds, keeping at least two yards from other people, isolating yourself even if just...

@jkokich ImThis quarantine is for more than staying home when you feel sick: it is also about isolating yourself when you do not have symptoms but might be infected and contagious due to close...

@jkokich a RN recommending hand-washing does not render the rest hype; and that is certainly not the _only_ action that medical experts are recommending. Perhaps you should listen more to what...

If there were ever an organization that could hold a conference online, it could be the National Association of *Broadcasters*. (Meanwhile, much of my profession of higher education is moving...

@sirhawkeye, Agreed that the Fujifilm X system has lagged on video specs (and IBIS) till now, but the X4 changes that. So maybe they have not abandoned video entirely! Maybe they were late in...
