mosc: Why 1" instead of 1/1.7" or APS-C? Because it's the right balance. You can deliver reasonable aperture for 1" (FF f8 equivlanet is f2.8 on 1") that gives reasonable depth of field and you can make a smaller lens sharper, cheaper.

The physical size of the lens and the aperture you want (say f8 equivalent) is going to determine the optimal image sensor size. If you want f8 at 200mm like the RX10 offers, you know your aperture is going to be a known size. If I did my math right that's a 22.2 mm wide aperture. This is the physical constraint on the lens you must hit. If you have a larger sensor behind that or a smaller sensor behind that, the physical lens you come out with will be different. APS-C superzoom lenses will be physically wider and could be stubbier where the smaller ones can be closer to the theoretical aperture width in diameter and longer.

In other words, if you want a self-contracting lens the smaller sensor is a benefit but there's a limit (22mm here) hence 1" RX10.

You got it backwards. No matter what the sensor size is a full FF equivalent lens with EQFL=200mm and EQF-stop=8 will have the same pupil size of 25mm. The lens for the larger sensor will be longer, but not wider. And since the lens is collapsible, the size of the camera won't change.

jaykumarr: My observations in this pic:
1) Sony is a bit sharper at center & top left. Everywhere else Panasonic is sharper.
2) There is chromatic aberration in panasonic's output.
3) The panasonic has better lens, while sony has better sensor.
4) Sony applies a little more denoising in default mode than panasonic.

I wish dpreview do comparison in long end too.

regards,
jay

Yes, the left and right sides seriously differ. Looks like either there is a misalignment in the test bench, or the lenses are decentered.

Biological_Viewfinder: Because of this website, I have purchased several Panasonic cameras over the years. But I've come to the conclusion that there has never been a top-notch Panasonic anything, ever.

The Sony isn't perfect, but I'd rather pay $1300 for the Sony Rx10 and have a camera that produces output that I can enjoy, than pay $800 for a Panasonic that I won't even use because the output is lacking.
-
Once again, let me remind you that I've purchased several cameras from Panasonic over the years. *NONE OF THEM* produced images that were useful to me. I've owned the Nikon D800e and others. I was *NEVER* happy with any Panasonic product. My biggest complaint is the ugly, chunky noise and horrible low-light capabilities.

My experience with Panasonic was similar, more noise than competitors and hard to get good colors.

forpetessake: The only amazing thing about Lytro is that after all these years the investors haven't thrown the towel yet.

If somebody wants to buy the Lytro assets they would just wait until the company goes kaput and liquidate what's left for next to nothing.

I guess hype works! Otherwise how can you explain all this ballyhoo going on? The camera's only achievement is that it fits in a pocket, the lens is pretty unremarkable, and so are the images.

The noise depends on the exposure, not the ISO per se, though the read noise contribution increases the lower the ISO.

mauijohn: The japanese plan after they occupied the Philippines is to mine all the natural resources of the entire island of the Philipines such as copper, gold, timber, iron etc. They will use the people of the Philippines to work manually young and old and they just killed those too weak to work. Japan has a very low on those natural resources on their land. I will called this big time terrorism that will look Boko Haram and alquida combined like a chiken.

jaykumarr, calling you a moron was an understatement, you are clearly an imbecile. And, yes I have a PhD from a prestigious American university.

plasnu: Does anyone still choose DSLR over this at this price point?

Many ordinary (i.e. ignorant) people buy DSLRs mostly because it's a Canon or Nikon. Those brand names mean a lot.

larrytusaz: Having shot with the NEX-6 before I would miss the level gauge. I can't shoot a level landscape without one if my life depended on it. There's always a Joby aftermarket spirit level, but then you can't see it if you're using the EVF. Why in the WORLD was this left off from the NEX-6?

However, I love what they'e done with having so many AF points covering so much of the frame. This is something that DSLR makers still don't seem to get--we don't want to have to "focus center and recompose," we want to compose as-is and then be able to place an AF point pretty much wherever on the screen with our current composition already accounted for. Even models like the D7100 don't provide enough coverage, to say nothing of the D3000 and D5000 series. Whenever you say "I want about 150 AF points covering the WHOLE screen" they look at you like you're asking for the moon or something. Sony proves that in fact you're not asking that at all.

What can be easier than correcting the image in PP? Moreover, I would have the 3x3 grid lines and not the level turned on, it's simpler to align the horizon with the grid than trying to catch the level.

FiveForm: I'd love to see Sony make a G series, 16-85mm f2.8 walkaround lens for the a6000. Not sure if they can manage the top end being that long, but one of my favorites for my Nikon D series cameras was their 16-85. I'm currently shooting the Sony original 18-200mm and while nice, it's just too heavy and bulky and makes a small, light ILC a bit too cumbersome. Zeiss glass is great, but they know it and charge through the nose. I can buy two decent Nikon prime or zoom lenses for the cost of one Zeiss prime.

Sony should copy the lens roadmap from Fuji, they did all the right choices. If only Sony also could approach Fuji in optical quality ...

Herschel: I'm debating the RX100 M3 over updating my NEX-5N body to an a6000.

The f3.5 kit lens vs the f1.8 lens in the M3 means you can shoot at roughly 1/4th the ISO on the M3 to get equivalent IQ on the a6000. The studio shots bear this out - ISO 1600 on the M3 looks indistinguishable from ISO6400 on the a6000.

Sony has done a great job on their cameras - I just feel like they need to spend more R&D on their lens lineup like Fuji has to make their mirrorless portfolio compelling.

The RX-100iii lens is equivalent to 16-46mm f/3.3-5.0 lens in A6000. So you get very close performance to the kit lens. But that's not the end of the story. With interchangeable lens design you have a choice of many lenses, from small pocketable ones to large telephotos. For most people who are the target market of the NEX/A6000 cameras, the RX is simply not an acceptable trade-off. Though it's a reasonable solution to get RX in addition to A6000 and get rid of the kit lens.

G1Houston: Is the lack of an external charger really a negative?

I have come to appreciate the fact that when I carry these cameras on a trip, I do not have to pack all the bulky chargers with them. I just have to bring a single USB cable that I already use to charge my phone and tablet. Is that really so difficult to charge a separate battery at night time in the camera? It is also possible to use those external batteries we have for the smartphone to quick charge the "camera" in the filed. I thus suggest Dpreview to reconsider calling the lack of external charger a "pro," to encourage companies to simply the accessary. It drives me mad that each one of my camera has a different battery with a different charger.

External charger should have been included, it's pretty much a necessity with those small batteries. One or more batteries (depending on use) should always be charging while camera is in use, so you can swap them. Sony simply decided to hide the charger cost from the price of the camera.
And it's correct that the USB charging is very slow. USB port is rated just 0.5 amp.

This is typical of Fuji cameras. Red shows wrong color shift and void of any details.

When will DPR show us masterpieces of somebody taking pictures with camera obscura? It also offers distinctly 'old fashioned' look.

The lens is rather soft, especially wide open. But for most people who buy this camera the resolution will be sufficient because they are likely to view their pictures on tablets and phones.

You can avoid paying US sales tax by ordering out of state(except if you live in People's Republic of New York). I usually buy from B&H tax free, plus perks. I'd like to see how people can avoid confiscatory taxation in EU/UK.

Only those who pay little or no taxes love high tax rate paying by all who work hard to achieve their prosperity. Another word for socialism is parasitism.
