I have never owned a Leica M or R camera, but I have been using the Leica Digilux 1 for 18 months, and apart from a few operating niggles (which I'll explain), it has been a superb camera. I can't understand the comments above about build quality: it is beautifully made, rugged, handsome, and fits the hand very well. Most important, it takes superb photos. The lens is excellent, as is the metering system: together with the 4Mp sensor they produce A4 size prints of stunning quality, and A3 size of very acceptable quality (provided, of course, one uses a decent printer ike an Epson 2100). Indeed, only last weekend a professional media friend was visiting, and I showed him some A4 enlargements: he said they were so good he could not believe they came from a digital camera, or any camera. I'm therefore looking forward to the Digilux 2, not because the Digilux 1 has any major failings but because the 2 seems to address some of the shortcomings of the Digilux 1 that have become apparent to me in use.
First, the minimum aperture of f/8, along with a minimum shutter speed of 1/1,000th sec. sometimes means there is too much light for the camera, and unless one puts on a polarising filter or ND filter, the image is over-exposed. Second, while the large LCD screen is wonderful for reviewing images, I don't like it for composing photographs (it's awkward to hold like that), and since the optical viewfinder displays ZERO information on aperture or shutter speed or anything else, I feel handicapped. Third, the autofocus suffers, like all autofocus systems, from hesitatiuon in low light/low contrast situations.
The Digilux 2 will address all of these. Better lens, faster shutter, manual focus, manual zoom, innovative electronic viewfinder (which actually makes it more like an SLR than an M6 or M7). Moreover, the new 5Mp sensor promises to be outstanding. Remember, it's not just how many pixels there are, but what size they are and how they arranged. If you cram 27 million pixels into an area the size of a pin-head, you're going to get crap photographs. Put 5 million pixels of optimum size into a larger-than usual area, and you will get higher quality images. This is where the Canon/Nikon/Kodak/Fuji/Minolta etc. advertising can get so misleading: punters just buy the largest number of pixels they can afford without any thought to other relevant criteria. Look also, for ex&le, at the Olympus E-1, which has a 5Mp sensor yet garnered rave reviews in the press here: a 94% rating in Amateur Photography last month.}}
I know I sound like a salesman for Leica. Believe me, before I bought the Digilux I was as sceptical of the Leica myth as an Olympus user, but the results speak for themselves.
