Panasonic Lumix DMC-GX1

Especially if you've invested in extra lenses, even with these mirrorless cameras the lenses can quickly become more expensive and longer lived than the cameras themselves.

Even with this issue, I absolutely love this camera for the quality of the still pictures... especially with the 20 mmf/1.7 lens, which costs almost as much as the camera, but is worth every penny.

The versatility of the system just seems stronger here, you can use almost any lens you want, while with Panasonic, it feels you need to use their lenses.

the Built In flash(Flexible bounce ), LVF2, Focus speed,Touch Focus and touch shutter were really a trend setting features which I was looking for...The rock solid lowlight performance is a eye catcher, the retero style and black -silver body is a Hot Rod design for a Mirror less camera with Inetrchangable lens.

As with its sibling cameras, the GX1 has a great hybrid interface, which can operate either via the extremely customizable touch screen or completely via the hard controls; for instance, you can select which options appear on the Quick Menu, place the histogram anywhere on the screen, and perform almost any operation with either the buttons or touch.

Touch Tab is a brand new feature that provides an onscreen dock for up to five control and display functions that can be expanded or hidden with a single touch.

The 16MP panasonic sensor has great resolution, but the high-ISO performance is not quite up to par with the best 1.5x format sensors, even when considering the smaller crop factor.

The Olympus has a 10 megapixels sensor that is about 1/4 of the size of the GX1 sensor (16 megapixels).

The maximum ISO I reach in most situations is ISO1600 and this camera is perfectly capable of handling that, so it's a big plus for me.

We have always been impressed with the AF performance of the G-series cameras compared with competitive systems that also use contrast-detection AF and even some entry-level DSLRs.

We'd expect a better hit-rate from true phase-detection AF systems, but from a camera of this type, we're impressed.

One stays put where you focus it, one is an active focus, and one apparently continuosly adjusts focus- I have not figured out yet the difference between the last two.

The combination of size, good looks, image quality and overall convenience is hard to beat at the moment.

The additional pixels are useful, but not as relevant as the overall improvement in image quality.

IQ (image quality) is outstanding, I'd say 90% of the Nikon D700.
