martinj68: looking forwards to the RX10M2 review, any ideas when?
Do you get a production unit of a7r2?
Cheng Bao: It is suspicious that the RX100III/G7x/LX100 3-way real world shoot out not appears in any reviews of above cameras, but RX100IV.
I smell conspiracy theory.
You only have studio shoot out in LX100 reviewhttp://www.dpreview.com/reviews/panasonic-lumix-dmc-lx100/9
Not this real world shoot out.
Edit: oops, it is hidden under menu

many links are 404 error, I tried links under What's New -> Auto Focus, none of them are working right now
404 error when I try to click the link to read preview.
What's the last time that dpr reviewed a casio camera?
deep7: That chart (and comment) in picture 3 is a bit misleading. You have the focal length on a logarithmic scale which makes the differences between the chosen cameras look minor. In fact, the Canon offers THREE times the focal length of the Sony and 50% more than the Panasonic, which is why I would instantly dismiss the Sony, think about the Panasonic but seriously consider the Canon.
Likewise, the vertical scale starts at f4 and makes the one/two stop aperture differences look much worse than they are.
Finally, for a bush/travel/general purpose camera, being able to have more depth of field is an advantage. People on this site constantly forget that. Yes, I know it's not trendy...
Keep, in mind, F2.8 offers FOUR times more light than F5.6, and F4 offers TWO times more light than F5.6
Cheng Bao: It is a little redder than conventional camera, as http://www.dpreview.com/reviews/image-comparison?attr18=daylight&attr13_0=nikon_d810a&attr13_1=nikon_d810&attr13_2=canon_eos5dsr&attr13_3=nikon_d750&attr15_0=raw&attr15_1=raw&attr15_2=raw&attr15_3=raw&attr16_0=200&attr16_1=200&attr16_2=200&attr16_3=200&normalization=compare&widget=1&x=0.4110061397643234&y=0.35088612541026437
D810A has more red tint across the frame, the only exception is where dpr use as example to prove D810A has no tint-- the palette.
I guess the pigment of the standard palette is special that it reflects less infrared than normal particles.

Cheng Bao: I believe firmware of old O.I.S lense would be upgrade to make dual IS working.
ok, after reading hand-on perview, seems I was correct.Still a feast that IBIS and lens IS can work in same time.

FrankS009: The RX100 is not that light. It is heavier than a Panasonic GM1 with a 12-32mm lens (and a much bigger sensor) , and only 100g less than a GX7.
For that a few grams higher, RX100 3/4 offers:24-70/4.9-7.6 equiv lenswhile GM1 only have24-64/7-11 equiv lensThat's a full stop advantage.plus tilt LCD, EVF, and a much smaller form factor to fit shirt pocket.
*What finally enabled the use of on-sensor phase-detect information to drive adapted DSLR lenses? Our best guess is the increased speed of sensor readout. If you have any thoughts or guesses, please comment below.
Well, increasing read out speed would certainly help, however, consider a6000 vs a7R2, the former has high read out speed too, however, the AF speed on a7r2 is not much faster than a6000, but AF speed on DSLR lenses is much faster.
This indicates something else play here. My guess is all native lenses are capable of doing rapid small AF movement while DSLR lenses can't. Previous bodies still send out rapid AF steps commands, even with DSLR lenses, with exception of LA-EA4 adapter, now when A7R2 detected adapted lenses, it will change af pattern accordingly, I won't be surprised if Sony stored canon lense database inside.
Good to know that stellar is a profitable camera.
weixing: "And even if they don't show up, don't worry - you can just use Canon's. "Hmm... IMHO, that's a very risky business strategy... if Canon start to encrypt their lens control signal or slow down focusing speed when use with non-canon camera, then Sony user will have big problem.
The problem of canon is not whether they got the tech, the technology is not rocket science, even Panasonic, aptina, Toshiba, omnivision can do on sensor ADC, almost all sensor makers except canon have the technology.
The problem is when canon decide to ditch existing fab production lines? Either to embrace new technology, or just buy sensors from others.
watson076: Hey let's not forget about Canon as they really have done the impossible by managing to sell the same sensor for over a decade. Now if only someone would come up with a camera that only shoots black and white and sell it for several grand ;)
"Now if only someone would come up with a camera that only shoots black and white and sell it for several grand ;)"
I believe a company started with letter "L" already did it, twice.
Zero polycabonate: It's just too bad its out of the price range of the vast majority of consumers.
But the beside prisms, OVF do need have eyepiece lenses too, plus focus screen, mirror box, dedicated PDAF sensor, meter sensor and so on, all of them need to be calibrated thus increasing labor cost. The $270 price I remembered is prism alone.
@pkosewski I am sure sensors in A7r is much cheaper than D810, so does the price, $2300 vs $3300 release price.
But I am talking about sensors in a7r ii, which is much advanced, and not gain economies of scale yet.
sony parts website, while it was public accessible, listed A900 prism part price is around $270, and APS-C, none 100% coverage model is $100 cheaper.
This price is by no means production cost, but it indicates the prisms are not cheap. 100% coverage prism is very expensive esp. when you take account of the precise assembly cost.
A7r ii is actually priced same as 5D series and D800 series.the release price of 5Diii is $3500 body only, D810-$3300.
Of course the manufacturer cost would be considerably lower than 5D iii and D810, since lack of mirror and prism system. I would expect price is much lower then one year later, when initial R&D cost (which could be much higher than 5D iii and D810 consider the feast of the sensor) paid off.
