Image Quality

All of the sample images in this Review were taken using the 10M Fine (3648x 2736) JPEG image size option, which gives an average image size of between 4-5Mb.

The Panasonic Lumix DMC-LX3 produced images of very good quality during the review period. The Panasonic Lumix DMC-LX3 dealt extremely well with chromatic aberrations, with limited purple fringing effects appearing only in high contrast situations. The pop-up flash worked well indoors, with no red-eye and adequate exposure. The night photograph was excellent, with the maximum shutter speed of 60 seconds allowing you to capture plenty of light. Anti-shake is a feature that sets this camera apart from its competitors and one that works very well when hand-holding the camera in low-light conditions or when using the telephoto end of the zoom range. Macro performance is amazing, allowing you to focus as close as 1 cm away from the subject (although it's difficult to get the lighting correct at such a close distance). The images were a little soft straight out of the camera at the default sharpening setting and ideally require further sharpening in an application like Adobe Photoshop, or you can change the in-camera setting if you don't like the default results. The 1/1.63 inch, 10.1 megapixel sensor used in the Panasonic Lumix DMC-LX3 produces noise-free images at ISO 80, 100 and 200, with limited noise starting to appear at ISO 400. ISO 800 exhibits quite visible noise and loss of fine detail, and ISO 16000 and 3200 are even noisier (the latter setting is almost unusable).

Noise

There are 7 ISO settings available on the Panasonic Lumix DMC-LX3 which you can select at any time if the camera is in one of the creative shooting modes. There is virtually no discernible noise at the slowest settings of ISO 80, 100 and 200, and ISO 400 also looks fine, with some noise creeping in. More obvious noise and slight loss of detail is apparent at ISO 800, particularly in the shadow areas, and at the fastest settings of ISO 1600 and particularly ISO 3200, image quality has deterioated a lot. There is a High Sensitivity mode that goes up to ISO 6400, but it should be avoided at all costs as the results are terrible. Here are some 100% crops which show the noise levels for each ISO setting:

ISO 80 (100% Crop)

ISO 100 (100% Crop)

   

ISO 200 (100% Crop)

ISO 400 (100% Crop)

   

ISO 800 (100% Crop)

ISO 1600 (100% Crop)

   

ISO 3200 (100% Crop)

 
 
   

File Quality

The Panasonic Lumix DMC-LX3 has 2 different JPEG image quality settings available, with Fine being the highest quality option. Here are some 100% crops which show the quality of the various options, with the file size shown in brackets.

10M Fine (4.14Mb) (100% Crop)
10M Normal (2.00Mb) (100% Crop)
   

Sharpening

Here are two 100% crops which have been Saved as Web - Quality 50 in Photoshop. The right-hand image has had some sharpening applied in Photoshop. The out-of-the camera images are a little soft at the default sharpening setting, and benefit from further sharpening in a program like Adobe Photoshop. You can also change the in-camera sharpening level by tweaking the Film Mode, with five different settings available.

Chromatic Aberrations

The Panasonic Lumix DMC-LX3 dealt extremely well with chromatic aberrations during the review, with very limited purple fringing present around the edges of objects in certain high-contrast situations, especially at the telephoto end of the 2.5x zoom.

Macro

The Panasonic Lumix DMC-LX3 offers a Macro setting that allows you to focus on a subject that is just 1cm away from the camera when the lens is set to wide-angle. The first image shows how close you can get to the subject (in this case a compact flash card). The second image is a 100% crop.

Flash

The flash settings on the Panasonic Lumix DMC-LX3 are Auto, Auto/Red-eye Reduction, Forced Flash On, Slow Sync./Red-eye Reduction and Forced Flash Off. These shots of a white coloured wall were taken at a distance of 1.5m.

And here are some portrait shots. As you can see, neither the Flash On setting or the Red-Eye Reduction option caused any red-eye.

Night Shot

The Panasonic Lumix DMC-LX3 maximum shutter speed is 60 seconds in the Starry Sky Mode scene mode (there are also 15 and 30 second options) and also in the Manual mode, which is excellent news if you're seriously interested in night photography. The shot below was taken using a shutter speed of 15 seconds at ISO 100. I've included a 100% crop of the image to show what the quality is like. The camera takes the same amount of time again to apply noise reduction, so for example at the 15 second setting the actual exposure takes 30 seconds.

Anti Shake

As with all Panasonic compacts, the DMC-LX3 has an anti-shake mechanism, which allows you to take sharp photos at slower shutter speeds than other digital cameras. To test this, I took 2 handheld shots of the same subject with the same settings. The first shot was taken with anti shake turned off, the second with it turned on. Here is a 100% crop of the image to show the results. As you can see, with anti shake turned on, the images are much sharper than with anti shake turned off. This feature really does seem to make a difference and could mean capturing a successful, sharp shot or missing the opportunity altogether.

Shutter Speed / Focal Length

Anti Shake Off (100% Crop)

Anti Shake On (100% Crop)
1/8th / 24mm
1/15th / 72mm
     

Aspect Ratios

The Panasonic Lumix DMC-LX3 offers 3 different aspect ratios; the following images give you an idea of exactly what is captured at each setting.
