Re: Ricoh GXR + A12 50mm
Guillermo,
I was looking at the specifications of the Panasonic DMC-GF1, and realized an error exists in my post relating reviews/test/opinions of the Leica X1. So I corrected and updated that post. For your convenience, that update (from my updated post) appears directly below:
(2) It has a large image sensor (23.6 x 15.8 mm) that is only about 22% larger (in pixel-size) than the DMC-LX3 - yet, for all that extra active sensor size, appears to have virtually the same "chroma-noise" as the Panasonic GF1 (with a smaller 17.3 x 13.0 mm image-sensor size, about 52% higher pixel-density, and a measured 20% higher actual measured ISO sensitivity in-camera):

Correction (May, 15, 2010):
Actually, from the following images within DP Review web-page linked below, the Leica X1 (compared to the Panasonic DMC-GF1) is:
> Better where it comes to "chroma" noise test results:

> Better where it comes to "grey" noise test results:

> Worse (below around ISO =1100) where it comes to "black" noise test results:

Well, DM, I did my homework. Let me explain what I need for my photo project... (and I will be pleased to have your detailed analysis you always do).
Well, all of my cameras have been humble "point and shoots" (DMC-LZ5, DMC-TZ4) and (sometimes called) "pro-sumer"/"bridge" cameras (DMC-FZ30, DMC-FZ50, and DMC-LX3). I've been taking and post-processing pictures (entirely on a non-professional basis) for a mere four years time. The results I get are more the result of patience, tenacity and dedication than due to expensive hardware/software. I have not done more than read about Micro 4:3, dSLRs, etc. So, I don't feel at all qualified to comment as a "serious 'real' photographer" ... But I would say that the various information that I collected and quoted and linked-to in my Leica X1 related post certainly appear to (in total) characterize it as a low-noise, but very limited and problematic camera to actually use in practice. From what I have read about it's overall functionality (or lack thereof), I don't think that I (personally) would purchase a Leica LX1 at any price ...
... I need a medium pocket-size camera with a "real" IQ quality to make fine art prints with little work in NR.
... Will the Leica X1 be that camera? Check this thread about "real" X1 users (
http://www.l-camera-forum.com/leica-for ... ca-x1.html)
I read most of the pages of the thread. The thread looks like an unmitigated "fan-boy" festival, full of short emotive snorts. I looked at the linked "actual LX1" photos (that did not require registering as a member of the Leica Forum in order to view them), and while it does appear that the Sony image-sensor does have a very good dynamic-range, only a few of the images that I viewed looked interesting, many appeared mediocre and limited (perhaps as much by the camera-persons as the camera itself). Anybody can join the Leica Forum and say positive things - but I find myself not putting a lot weight in the words of folks who do not produce "real" images that truly impress me personally. (For me) such "home-team" forums are the least reliable sources of all.
... I don´t rely in dpreview threads or reviews. They are industry oriented, not user oriented. I don´t care about comparisons and so on. I just want a serious "real" photographer opinion.
Soon I´m getting a very important grant in my country to execute my own personal project, and the right Digi-camera it´s the key in this project, no matter if it cost 500 or 2,000 US dollars.
Sounds like the best serious "real photographer" for you to rely upon is
you!
Perhaps borrowing/renting a Leica X1 and seeing what you really get from it is the only way to know for yourself!
There are 15 Leica X1 "raw" image-files at this Photography Blog web-page that you could download:
http://www.photographyblog.com/previews ... x1_photos/
Some of them look like they might help to give you a good idea of what you can expect from the Leica X1.
There are 9 Panasonic DMC-GF1 "raw" images-files at this Photography Blog web-page that you could download:
http://www.photographyblog.com/reviews/ ... le_images/
The DMC-GF1 features user-implementable "pixel-mapping". It is likely (but not certain from my research) that
the results of the pixel-mapping are used to (also) correct
the "raw" image-files (similar to certain Pentax
camera models, as well as the Adobe 2008 DNG file-format standards for DNG-recording camera nodels).
The Panasonic Lumix DMC-GF1 12.1MP Micro Four-Thirds Interchangeable Lens Digital Camera is $749 USD at:
http://www.bhphotovideo.com/c/product/6 ... html#48342
but this is with the 14-45mm f/3.5-5.6 Lens (which has lens-based optical image stabilization, but is fairly large and bit heavy).
Adorama (through Amazon.com) has the DMC-GF1 NEW with the 20mm "pancake" lens for $865 USD at:
http://www.amazon.com/gp/product/B002MU ... C6HOH9AVE6
The LUMIX G 20mm f/1.7 Aspherical Lens is $399 USD at:
http://www.bhphotovideo.com/c/search?Nt ... Search=yes
and may well fill your expressed desire for a small, light, pocket-able item.
However the 20mm "pancake" lens does not have any optical image stabilization
(on the other hand either does the Leica X1, according to):
http://www.luminous-landscape.com/revie ... ield.shtml
From the looks of the side-by-side JPG comparisons at the Luminous Landscape link (above), it looks like the Leica X1 and DMC-GF1 both look pretty good up to ISO=800, whereas the Leica X1 is clearly better than the DMC-GF1 at ISO=1600 and above.
For photographing artwork, ISO=800, the maximum aperture of F=1.7 of the Panasonic "G-series" 20mm "pancake lens", and a Shutter-Time of 1/100 Second take you down to an Exposure Value (ref. ISO 100) of 5.18. That's a rather low level of (even indoor) lighting (which is good). Without image stabilization you might (unfortunately) want a Shutter Speed of => 100 for
hand-held.
If the "artwork" that you refer to is not (just) 2-dimensional, bear in mind that Depth of Field is
significantly lower with these larger image-sensors.
Setting the F-Number at 2.8 (X1) or 1.7 (GF1 with pancake lens) and shooting at close ranges is certainly is not going to help the Depth of Field situation ...
The little that I have read about the Olympus E-PL1 looks (to me) to be somewhat troubling:
viewtopic.php?f=36&t=4267&p=18979&hilit=+Olympus+PEN#p18973
Marana had a "hands-on" look at one, her impressions are at:
viewtopic.php?f=36&t=4267&p=18979&hilit=+Olympus+PEN#p18976
(For close-range work, and where more than 1.5x Zoom is not necessary) the Panasonic DMC-LX3 ($399 USD)
combined with DxO Optics Pro 6.2 Standard Edition (offered at a mere $99 until June 15, 2010) is small, light,
pocket-able, has a F=2.0 lens-system, and has highly effective Optical Image Stabilization on-board. It can do
a good job shooting up to and including ISO=400, requiring only
very small amounts of DxO Noise Reduction.
The Depth of Field with the 1/1.63 Inch image sensor is excellent (about the same as the Ricoh GRD II and GRD III).
DxO's unique "Lens Softness" corrections with their "raw"-mode Optical Correction Module are outstanding! ...
(Though a larger, heavier, and more expensive camera option), DxO OP 6.2 Standard Edition also supports the
DMC-GH1.
As I indicated, I have just read things here and there about all of these cameras (other than the DMC-LX3) - and I do not have an "objective" overview about all of the possible options that you might find available in your search for this particular type of camera model. But perhaps some of this information may be helpful to you, nevertheless ...
Your reported favorite "raw" processor (Silkypix Pro) appears to support the Leica X1 as well as the DMC-GF1. See:
http://silkypix.shortcutinc.com/silkypixpro/cameras.php
So, do let us know what you think after you have taken your hand to some investigatory "raw" processing and development! ...
