Leica D-Lux 4 - Test Shots - ISO Performance

Leica D-Lux 4


Our Score:


Over the next few pages we show a range of test shots. On this page the full size image at the minimum and maximum ISO settings have been reduced to let you see the full image, and a series of full resolution crops have taken from original images at a range of ISO settings to show the overall image quality. These pictures were taken indoors using shaded natural light.


This is the full frame at 80 ISO.


At the minimum ISO setting the image quality is every bit as good as the LX3.


Almost no difference at 100 ISO.


Still no problems at 200 ISO.


There is a little noise visible at 400 ISO.


More noise is visible at 800 ISO, but it is well handled.


At 1600 ISO there is quite a bit of noise and some colour distortion.


3200 ISO is looking pretty shabby.


This is the full frame at 3200 ISO.

I bought the LX3 Dec' 08 and it has been fantastic. It was a toss up between the LX3 and the Canon G10, but thanks to the reviews on TR, I picked the better camera. I didn't realise Panasonic had stopped making the LX3, can you still buy lenses/barrels/filters etc?

loving the spot the difference competition on the last page ;D

the colour seem a little icy on the lx3, when compared to the dx 4 (i refuse to say "deluxe") - is that normal, or just the settings where the lx3 has been used and calibrated a little more?

I looked at the two photos from the LX3 and the DX 4. IMHO the pic from the Panasonic looked sharper. Colors etc. looked the same.

ilovethemonkeyhead - Both cameras are virtually new, having each taken only a few hundred shots. For the test shots both were set on aperture priority at f/5.6 and 100 ISO. The Leica's meter set a shutter speed of 1/125th, while the LX3 set 1/100th.

If you open both images in a photo editor and flick between them, the Leica does seem to have a slightly warmer tone, although that could just be down to variations in auto white balance. The file sizes are slightly different too, with the LX3 producing a slightly larger file.

There are at least four reasons to explain the premium price compared to the LX3. One: you'll get more for a Leica when you decide to re-sell your D-Lux4. Two: Leica has a reputation of offering much better (and longer) technical support compared to Panasonic. Three: the software that comes with the camera is better/more expensive. Four: You get 2 years of warranty (compared to 1 for the LX3).

FWIW, I 'm a very happy LX3 owner.

The software that comes with the camera - Capture One 4 - is very good but Leica have just e-mailed me to say it is not compatible with Windows 7.

As I bought the camera last week and run Windows 7 I am less than happy.

Apparently Capture One 5 is compatible with Windows 7 and can be had for 299 euro or $399.

You pay a lot for the little red leica badge.
