The D-Lux 4 is as simple or complicated as you want to make it, and offers a wide pallet of responses to any situation.
It took a while to get used to no viewfinder, but now it is second nature.
I often use a tripod and I couldn't be happier with the results. I have had mine for a year and a half, and know the D-Lux 4 pretty well now, and to me it is technology at its best.
Macro-shots from unbelievably close (sub 1 cm), autofocus great, lots of manual settings, light, has RAW, sturdy body.
The lens cap needs getting used to, sometimes you may loose a great shot... Some manual features not so easy to understand/learn, lens with open cap gets easily greasy fingerprints...
Great camera after my stolen C-Lux2; love the additional (manual) functions and larger display. Completely worth its price.
