glokenpop: This looks like a great camera I'll probably go this way once my 5DIV is getting long in the tooth. I still look at Sony, Fuji, Olympus, Panasonic and Nikons with envy. I'd love to have setup from each camp if it wasn't for monies the extravagance of it. Phone cameras a great too. Well done Canon.

I am proud to keep my 5DIII at hand with all my gears not sold...I believe this should be my 5D upgrade, ever since 5D1..I keep my fingers crossed wishing a comparable sensor found in A7RIII, with high dynamic range and low high iso noise

Cheapskate: So three years on, where are they? What happened?

Cant find any device using it though we can buy the cards everywhere

Honestly, despite my subscription, I have doubted the real use of my Flickr after all these years. I have to started to think of quit.

I thought D7500 and bunch of other DX cameras are good enough including my D500. Z50 offers everything except something new...like a higher pixel count sensor, IBIS etc etc. This is actually very good because I know Z50 sells very well and I am waiting for an upcoming better one

I will definitely vote 5D (which I have two) as the most influential camera of last decade and A7/A7r as the one in this decade.
RX100 scores well..and I can't agree Nikon 1/Samsung Nx Mini as a failure..from my point of view. Too bad Nikon used an inferior sensor to start with and Samsung, the most potential manufacturer, gave up too quickly. 1 inch sensor has every image quality an M43 has...and housed in a much smaller body chassis.

I do have a housing for SE but have never used it.
However, the idea of measuring diving bio stat should be an extra function to the camera housing, rather than complete replacement for dive computer which IMHO every scuba diver should have at least one on their wrists.

Is this one made for taking the crown of DxOMark scoring list? Look at the specs
108 MP (8P lens), f/1.7, 25mm (wide), 1/1.33", 0.8µm, PDAF, Laser AF, OIS
12 MP, f/2.0, 50mm (telephoto), 1/2.55", 1.4µm, Dual Pixel PDAF, Laser AF, 2x optical zoom
5 MP (upscaled to 8MP), f/2.0, (telephoto), 1.0µm, PDAF, Laser AF, OIS, 5x optical zoom
20 MP, f/2.2, 13mm (ultrawide), 1/2.8", 1.0µm, Laser AF
2 MP, f/2.4, 1/5", 1.75µm (dedicated macro camera)
I have been wondering how good their software is and how does it possible to make money for selling it at this low price?

stateit: '1/1.33" sensor'.

Isn't '3/4" sensor' easier to write and understand? Or have I got this wrong?

Easier for comparing to other sizes

milkod2001: Sony must have picked up some Canon camera engineers when working on R4. Very mediocre upgrades with half baked sensor. Would much prefer 50MP sensor with improved ISO performance ( better low/high ISO ), slightly better DR and camera to be capable of 4k60p in Super 35 mode. Everything on R3 was already great and on the end of day when you check on images you just can't see improvements in IQ in fact it you just get more mushy MP to work with.

I see 0 reasons to upgrade from my R3 and the worst part is that R5 will very likely have the very same sensor so i'll be getting the very same in 3 years time.

I finally found a hope to extend my EF lenses...though I can use them very smoothly on A7 series bodies

I think all these camera engineers have been working together for some time. BTW is there any rumour about 5D V?

Mark K: Having gone thru A7 A7r, A7rII...this version is a great for myself offering many of the expected features and improvement...and my even spare me from having A6600...a cropped size of 26MP is a very respectful size for bird shooters.

I kinda agree the 61MP sensor is a scaled up one used in XT30 and have been wondering why Sony didn't release a D500 killer and instead we were given a trio of a6100, a6400 and a6600 using a age old sensor. The release of Z50 proved my conspiracy theory that all camera manufacturers have agreed on the newer camera's spec so this explains why we still have inhibited touch screen, slower buffer clearance, lossy compressed raw file. Nevertheless this gives much room for an A7r V to improve..or otherwise, we will be more disappointed as what we see here an A9II is capable of.

RvEL: Seems like a solid screen. Their previous 4k was a bit too much in my opinion. 1440p would have been the sweet spot for this screen size (6.1 inch). Only real worries are the cameras on the back, in my opinion. For many, including my wife, the cameras are even more important than the screen. Lately, brands seem to strive for 1/1.7 or even 1/1.33. This will let in more light, thus result into better photos in general. No clue why Sony is still staying with 1/2.6 and 1/3.4 inch. :(

Maybe Sony is doing this for environment. However given the ever declining market share and relative less impressive camera performance, it takes risks to do so.

Mark K: 1/3.4 inch sensors used in this flagship compact camera? Sony, are you joking?

Sony makes the best sensors for smartphones and these sensors are far larger.

marc petzold: The new Z-Mount 24-120/F4 Lens seems to be quite interesting as "shoot-it-all" Lens, same as the Nikon F 24-120/F4 Zoom before, but i'd guess the IQ from this new Zoom next year would be a notch better. ;-)

Good Light.

With all systems I have Nikon is the only one which offers 24-120/4 with reasonably good quality.

While many successful smartphones are using much bigger sensors, which, until now, are produced by Sony, in their main front cameras. Sensor size and pixel size play a key role in the ultimate image quality.

I have this wonderful Sigma 120-300. It is sharp and its it's inexpensive, but it is also heavy and focal breathing heavily. At closer distance, its 300mm becomes 1xxmm, even shorter than 200mm. I hope this brand new Nikon will not give us the same problem.
