Tons o Glass 0 Class: In terms of rolling shutter in 4K video, this R3 is the best performing MILC to date, correct? I'm excited to see what Sony will do with their answer to this R3.

canon refresh rate 1/120sec sony A1 1/240 sec so no the canon is behind the sony.

nice looking camera, it better auto focus good 5yo cameras have faultless auto focus systems, wont mention any names.

Toms cat: Someone tell me honestly what you think of the Sony Speedlight hotshoe fitting , I would like to think all of the Press shooters aren't going to say that it's OK in the long term and break the Speedlight shoe contacts and have nothing but kind words to say !
Or stop using fill in flash - maybe

they are not fine wires at all.

if you look very closely they are not flimsy at all the contacts are solid gold inserts by the look of things.

Photodog2: That Nikkor 50/1.8S is obviously sharper than the other lenses. The lenses on the Em5iii and the XT-30 were designed to be portrait lenses so can be forgiven for not being as sharp. The Sony 55/1.8 was start of the art in 2013 and the best non-Otus 50ish, while the Nikkor is today's state of the art in lens technology so you can see how far lenses have improved in the last 8 years.

The X-trans filter is again a culprit, acting as a noise reduction filter that you cannot turn off, even at base ISO. If you replace the XT-30 with the XT-100 or XA-5, Fuji's Bayer filter bodies, they look a lot better with a very good JPEG engine. Of course, all of this is pixel-peeping, and the X-trans looks good at normal viewing distance.

Comparing the 33mp Canon M6 ii to the 20mp Zfc, the Zfc shows more detail even at pixel-peeping level which may be due to its no AA filter design.

All in all, the Zfc studio test shows an excellent sensor and one of the best 50s in existence today.

makes dpr pixel size doent mater a bit of a joke doesnt it.

PhilippeC95: Interesting idea !
Another potential benefit should be an improved cooling of the sensor+CPU, due to the extra surfaces for heat exchange.

exactly my thoughts as well.

Donald B: Quote from a good article: Similarly, large pixels collect more electrons than small pixels, so the point when the pixel flips from a 0 to a 1 can be much more precise. That in turn means far less data processing. With small pixels, the camera’s firmware is forced to extrapolate data.

true, but i have also seen the exact opposite with 3 top photographers choosing between 12 meg and 61 meg image 36inch print.

Donald B: You did say you were going to keep the test simple( shooting a portrait). now go and shoot a tree with the sun behind it with a 1/4 ff sensor and full m43 sensor and then post the colour of the leaves, the m43 leaves will not be green but grey, and the 1/4 FF sensor are still green. no one is interested in noise but colour reproduction.

photoaddict: I am pretty sure the dynamic range is lower on higher resolution sensor at high ISO. I am noticing how 12MP looks more saturated but we can easily adjust colors in editors.

But really, the truth is no one can really tell unless you magnify their weaknesses such as making the print much bigger than it can support ending up more pixelated or taking a photo at a higher ISO and the weakness of high resolution sensor will show.

But for all practical applications at this point, 24MP is really a sweet spot.

Crop the sensor and it still will.

It’s impossible

Your are right the colours are more saturated and accurate.

so your saying that 100 small speakers will produce the same sound fidelity as 1 large speaker ? dont think so :-)
