falconeyes: Still largely useless tool. Ok for noise and corner performance. Nothing else.
E.g., uses F5.6 70mm eq. for RX100m3 and F4 50mm eq. fir LX100. Can't be compared. E.g., F5.6 is F15.4 eq. and deep into softness by diffraction territory.

Rishi, how did you convert LX100's files? Is ACR updated for it? I thought not.

LX100 looks like a winner. Some have complained about lens wide open, in the longer review, please check that, since one of its most interesting features is the fast zoom.

Eric Calabros: Forget these compacts, look at that almighty D750
downscaled to print size, competes with A7S!

I'm getting both, the D750 and the Leica D-Lux 109 (=LX100)

:-)

intruder61: Too many guys believe the BS hype the manufacturers are throwing at you about how good these compacts are, then when they don't perform to what you want it to, out come the guns....compacts are compacts are compacts, small sensors, nothing special, it is what it is....and here is the special, you get shafted by paying premium price....entry level DSLRs with APSC sensors for less $$ are a whole lot better value...oh yeah i forgot, the DSLRs dont fit in your back pocket while you're having coffee down at the cafe.

I am getting the V-Lux (same as LX100), to go along with the dlsr system, which I can keep at a higher level (FF, for example), for more difficult or more requiring shooting situations. A compact this size is very handy, when you don't need all the capability of a dslr. Compare the LX100 size and bulk to even a small dslr or ml, when lenses are included (and kit zooms tend to be very slow, if you want a faster zoom, size, weight and price climb very fast).

Artpt: @Rishi Sanyal:

Way to respond... to a lot 'passionate' questions (I am thinking of Rodney Dangerfield in Back To School..."He really seems to care. About what, I have no idea")

Anyway, does noise relate to color channel...or are they all independent and more a characteristic of each sensor?

As always, thank you!

Color channel noise depends heavily on light source. Incandescent lighting, for example, has very weak B channel, which will cause WB correction to bring up a lot of noise in that channel. That's why we see two cameras having pretty similar noise when the light source has balanced colors, but one of them suffering of much more noise when channels are unbalanced, in low light situations.

Very nice performance from LX100, I'll be getting the Leica version, likely same. How did you convert its RAW files? I have checked the latest ACR update and the LX100 is not included. Am I missing something?

km25: The basic images look fine to me, in some I can see that depth you can get from high MP cameras. The thing I do not see sharpness of lens, like an hard detail of a old face with the unshaven look, you see very line. These image just to soft to me.

Good job Rishi!

Hugo808: It's got to the point where I can't tell the difference between cameras at all. If you told me these were taken with a 1" compact I would just nod and turn the page.

That they are full frame shots makes me impressed that the field has been levelled so much. But not that I'd be better off spending a lot on a new camera, not for reasons of IQ anyway....

You need to try them side-by-side, there is a difference. But a D90 is a nice camera, I got many very good images from a D80 ...

Indeed, finally some decent samples ;-)

The camera looks pretty good at this point, and seems to be a huge success among DPR users that have adopted it.

Realll: I would ask you WHY to buy camera with limited zoom and so small image size (only 12 mp)? The size of the camera is almost same as my Sony a5000 with 16-50, but Sony has big APS-C sensor and 20 mp images... Yes, I know- the glass is important. But amouont of light is approximately equal. So with Sony and 16-50I have same size, same zoom, almost twice bigger images for beautiful crops and I have it on half-price of the LX100... So again WHY ?

Which size do you print? Is APS-C really that big? How fast is the 16-50mm? How large?

majicmoments: I have handled the Lx100 and the 24mm end @1.7 is sublime.. with a dreamy shallow DOF.. it is such a quality camera that covers my most used focal lengths.. but like Damien, i am astonished that Panny have left out their tried & tested beautifull touchscreens.. and in this day'n age no tiltscreen.. which is a godsend for street/landscape & family photography.. Thank you Damien for such an interesting article.. more of the same please!

Except for AF, the touch screen is really not needed, with all these dials and buttons to work with.

Tilting LCD is a distraction, I prefer my camera smaller and w/o weak points (mechanically).

Lens, pure and simple, there's no m43 lens at size and price that competes with it. For those like me that already have an IL sistem, and are not interested in developing yet another one, the Panny/Leica compact is the best option.

Did you hear that, Nikon? They asked 7D users what they wanted and delivered. Nikon have been sleeping in their past glory in pro APS-C and now that market is gone for Nikon, simple as that. Mirrorless: again, when will Nikon give up on the N1 system, introduce a good 1" compact with fast zoom and launch APS-C ML and FF ML systems (should be new mount to reduce flange distance)?

Wake up Nikon!!! It's not only the cheap P&S market that is going down.

C'mon Nikon: D400 and a larger sensored ML system. I'm dropping the Nikon 1 system, Nikon never really cared much for it, never released a true enthusiast's body like a GX7 or the new compact LX 100, with decent controls and good VF. Nor a fast zoom. Also, they haven't released a single HQ zoom for DX in what? 10 years?

FF is ok, D750 is a true winner, but Nikon have been too conservative, they have wasted the great AF in the Nikon 1 on mediocre bodies with a small sensor.

This is looking like my next camera, it or its Leica sister.

In reply to:

Cal22: The LX100 aims at people who want an all-in-one solution. And the camera has a lot to like. I like especially the full manual control with control dials on the top plate for your right hand and a ring at the lens' mount for your left. And the camera body is big enough to making it not fiddly.

What I don't like: The camera has no tilting rear screen and no tilting EVF either. How to shoot from ground level? And a bundled flash should come up with more options than a built-in flash can provide; whether Panasonic will deliver in this respect, we may doubt until now.

The lens' zoom range is a little limited. Let's hope the image quality lives up to the name Leica!

How many times have you really used your cameras at ground level? Even if you do a lot, tilting VF/screen are not actually needed. I find the tilting screen useful for video, since you can hold it in a more comfortable position for a long time. That is relevant, shooting at ground level, not really.
