For the pro who is constantly changing ISO/Aperture/Shutter/ev/WB....the RX100 is worth the money.

That said, the RX100's sensor is twice the size of the LX7 with twice the resolution (20MP versus 10MP).

The RX100 has two ISO settings below its native 'base' ISO of 125 and, as you would expect, these both result in lower highlight dynamic range (since they are effectively the same as ISO 125 but with greater exposure).

the RX100 only has 1 lens, but WOW - It is an amazing lens, made by a well respected brand in lenses.

This camera is way better than buying any DSLR (around $700 range( and settling with cheap kit lens as RX100 has much faster and better lens than any kit lens that come with DSLRs)).

I especially recommend this cam for non-enthusiasts who just want P&S and not fiddle with the settings cause RX100 has such reliable full Auto mode coupled with large sensor and aperture virtually guaranteeing clean images in any light without adjusting setting or using flash all the time.

If you do not mind slightly impressionistic photos but great performance and excellent image stabilization in very low light, the HX30V is the best you can do with a small image sensor for even less than the LX7.

The Sony Cyber-shot DSC-RX100's maximum shutter speed is 30 seconds in the Manual mode, which is great news if you're seriously interested in night photography.

I found I could take pretty good low light shots with just these settings on aperture priority, getting depth of field and low light control within the understandable limitations of a camera having the RX100's focal length.

The dedicated Movie button on the rear of the DSC-RX100 allows you to start recording a movie with a single push of a button, and then stop recording by pressing the same button - a lot more intuitive than having to select the movie mode then press the shutter button, as on most compacts.

I like it that the NEX and RX100 can display MP4, AVCHD, or photos, but not everything in playback mode.

Present and correct is the increasingly ubiquitous ability to shoot High Definition video clips, but unlike its main competitors the RX100 does so at full 1080p HD rather than 1080i or 720p, and also with stereo sound rather than mono.

Other compact camera makers need to take a long, hard look in the mirror Here's the real reason why you'll want to pick up an RX100: the photos it takes are stunning to the point where all other compact camera makers will need to take a long, hard look in the mirror.

We think it makes much more sense in a small camera like the RX100, though, with the ability to achieve DSLR-like effects and image quality a real surprise given the camera's small size and light weight.
