I mostly take nature shots (flower macros, and the relatively unspoiled lush, riverine world of flora surrounding a favorite local creek). I sometimes take wide-field landscapes (but only around dusk/dawn when direct or first reflected sunlight does not tend to "blow the shot" somewhere critical within all that subject-coverage). The
horizontal width of the "perspective" of my mostly closer-range shots seemed not (in many cases) to be a large problem. If anything, it was more often a larger vertical height "perspective" that I desired.
Having (only) 4:3 aspect ratio display devices, I have shot (only) in 4:3 aspect ratio throughout. I often like to consider rotating the camera by 90 degrees, as a fair number of my shots end up "framing" better as a "portrait" orientation. A similarly rotated 16:9 frame (just about always) does not seem to appeal to my eyes (in a compositional sense). Thus, I remain a "4:3 aspect-ratio type" as it stands.
My first DMC-LZ5 was 38mm, so when I took on a DMC-FZ30, then a DMC-FZ50 (which are both 35mm), I did not notice the difference very much. Around 28,000 shots taken with those three camera models got me pretty used to an (approximately) 35mm perspective.
My DMC-TZ4 was 28mm which (at first) struck my senses as "more wide than necessary". It wasn't until I picked-up my (38mm) DMC-LZ5 again for a while that I noticed (and missed) the significant additional perspective of 28mm ...
Trading in my (28mm) DMC-TZ4 for the (24mm) DMC-LX3 in Dec 2009, I had a similar initial perception of "more wide than necessary". Now, 24mm seems "normal".
I am not saying that (full wide-angle) perspective is arbitrary - I am saying that (in my case) it is one of those things that is
most fully appreciated when it becomes more limited by some means (such as by using another camera with less perspective).
While the axis that people tend to concentrate upon and write specifications for is the
horizontal-axis , the "vertical height perspective" on the
vertical-axis can (in certain cases) be every bit as (or perhaps more) useful and valuable. It all depends on what you like to photograph.
That 24mm perspective may well have a hand in the DMC-LX3 lens-system having something on the order of 10% barrel-distortion. Panasonic in-camera JPG-engine and Silkypix (SE and Pro) seem to do only a half-ass job of correcting for this distortion over the range of focal length and aperture
Solution : Record RW2 image-files and process with DxO Optics Pro 6.x. It's fully automatic and comprehensive DMC-LX3 RAW Optical Corrections Module (based on over 1000 test-shots taken over a wide range of focal length and aperture settings) with "Lens Softness" (lens-blur) corrections (including "deconvolution-deblurring" performed prior to any de-mosaicing of the "raw" photo-sensor data) will likely "blow your mind". Your DMC-LX3 will never seem the same (in a very pleasing way), and future DxO support (who knows?) of the DMC-LX5 will likely play a very large part in how you view the potential of purchasing a DMC-LX5 ...
BTW - DxO Supports the Canon G10, G11, and S90 CR2 image-files as well. You just might well find yourself with similar (DxO-dependent) sentiments about whether to purchase a S95, as well.
Note : DxO might well choose to ignore the possibility of supporting the LX5 as well as the S95 (in that they are both so essentially similar to their predecessors).
Opinion : I would take the LX3 over a S90 any day. The Canon G11 image-sensor performs as well as the LX3's image-sensor at around +2/3 "stop" higher ISO Sensitivities - but the LX3's minimum F-Number of 2.0 gathers a "full-stop" more light than does the G11's minimum F=2.8. Optical "gain" beats "electronic gain" any day. And the G11 is one hulking, heavier, butt-ugly tank that is very hard to describe as "readily-pocket-able". Keep your DMC-LX3. You may (in retrospect) be glad that you did. Or, (alternatively), perhaps you could just send your DMC-LX3 along to me ...
