Upgraded to D-LUX 4 firmware Ver 2.1

Just upgraded the firmware of my Leica D-LUX 4 to the newly released version 2.1. According to the official release notes, "the exposure compensation and the auto bracket compensation can now be set up to ±3EV." This is a feature that I have been waiting for a long time.

Additionally, a standard "HIGH DYNAMIC" feature has been added to scene mode with this version.

Below are two HDR pictures testing the differences between ±1EV and ±3EV under the same low light condition and the same AWB setting, each directly generated from three auto-bracket shots by Photomatix Pro 3.2.6 using its default settings. No any other modifications.

Leica D-LUX 4 Digital Zoom Test

Digital Zoom (DZ) is a bonus feature available on most consumer digital cameras. Some low-end digital cameras "rely entirely on digital zoom, lacking a real zoom lens, as on most camera phones."

Personally, I never ever preferred using digital zoom because of poor zooming quality with additional noise. As a result, I always turned it off on my cameras if the functionality was enabled by default.

Leica D-LUX 4, as a top-end consumer level compact camera, also supports digital zoom up to 10x based on its 2.5x optical zoom. Probably because Leica defined D-LUX4 a semi-professional camera, as the Son of M8, digital zoom is disabled by default in this camera.

However, for having a better understanding on my Leica D-LUX 4, I was still curious about its ability of digital zoom. Therefore, several test shots was taken in different occasions, as shown below. Just click to download the original JPEG images with no any processing applied.

At first, three shots taken from the same standing place, and from the optical wide-angle end to the digital telephoto end.

Not bad? See below for the corresponding cropped images in 100% pixel with no processing applied. The two scenes in 300×450 pixels (at left) have been digitally zoomed into 2520×3776 pixels (at right) with more visible details.

Secondly, two test shots of the top of Sydney Tower taken from the same standing point in different zoom ratios.

All above shots were taken under bright daylight. How about indoor under varied lights? See the following test shots taken at a QVB cafe.

You can see the zooming quality and image noise goes bad, significantly, when the lighting condition becomes worse. Nevertheless, the camera's digital zoom works very well in certain lighting conditions, at least much more better than my expectation compared with other digital cameras I ever used.

As a result, for me, I have enabled Digital Zoom on my Leica D-LUX 4 in P/A/S/M modes. However, C1 and C2 modes still keep using optical zoom, ISO 80 and RAW as they are for serious photography.
