We should start with my recent review of the Sigma DP2 Merrill (DP2M). If
you haven't already done so may I suggest that you read it it now before
proceeding on this page? You should know that if anything my praise for that
camera is actually understated. The DP2M may have the highest per-pixel
usable picture resolution of any camera I have ever used and tested. No,
this is not Michael being hyperbolic. In recent weeks I, along with a couple
of other well known photographers who also bought their own DP2M (or have
been borrowing mine) have been doing comparisons with other gear in their
arsenals. In every case they (we) come away shaking our heads and vowing not
to publish what we see, because all it will do is stir up the trolls, and
create undesirable online nonsense arguments. Who needs the grief?
So, as preface to this report on the brand new Sigma DP1 Merrill (DP1M), I'
ll simply make one summary statement. It is my opinion that the Sigma DP2M,
for its part, provides the highest image resolution of any camera / lens
combination than costs less than a $2,000 – $3,000 dollars, and it
seriously challenges the IQ of cameras like the Nikon D800e and even medium
format backs in prints up to about 20X30". Part of the reason for this is
that the 30mm f/2.8 lens on the DP2 is simply superb. Not only is it a
remarkably sharp and aberration free lens, but it appears to be married to
the DP2M's sensor in a manner that means that the two work as a synergistic
pair, producing frame after frame that please and amaze.
No, the DP2M is not perfect. It's deathly slow to write files to cards,
though pretty responsive otherwise. The rear LCD looks like it's doing a
hula dance when the camera is moved, but overall the shooting interface is
fine. But, and it's a big but, this is not a camera for dilettantes. This is
a camera for the photographer who is willing to work for the shot, use
proper technique, shoot raw, and suffer with having to use Sigma's oh-so sad
SPP software before moving on to proper image processing programs.

Sigma DP1M @ ISO 200
The DP1M is an identical camera to the DP2M, with the only significant
difference being its 19mm f/2.8 lens (28mm equivalent). What everyone wants
to know is, is the 19mm lens as astonishingly good as its sister 30mm on the
DP2M. If it isn't then back to the dealer it would go, because to my mind
it's the unique combination of the 30mm and Sigma's X3 sensor that gives the
DP2M its magic. Unless the 19mm delivers to a comparable level on the DP1M
it may not provide the two camera combination that I think could shake up a
lot of photographers attitudes on how to travel small and light and with
versatility, while not compromising image quality.
After a week or shooting with the DP1M here is what I see. Basically, the
lens is the only difference between the models 1 and 2. It's very sharp in
the center 2/3 rds of the frame, but less so at the wide edges, and somewhat
soft wide-open in the corners. The corners sharpen up nicely by f/8. There'
s some vignetting and some chromatic aberration in the extreme corners.
Nothing that can't be fixed in Lightroom though in about 10 seconds.
Remember, this is a 19mm lens (28mm eqiv). As such it is no different that
other high quality wide primes. I don't know any lens in this focal range
that is without these issues, including those from Leica and Zeiss. Top
quality wide angle primes are simply hard to design and make.
The problem though is that the sensor is of such high accutance that even a
really good lens is challenged. A lessor sensor would be less revealing.
The DP2M on the other hand is an exception. The lens is simply superb, and
beautifully matched to the sensor. That camera is going to be a classic, and
unless one is looking for what's likely unattainable WA lens excellence the
DP1M will join it as well. Together than are a killer combo.
Recovering from the Fiasco
One of the biggest problems that Sigma has with their cameras is
reestablishing credibility. The SD1 pricing fiasco last year left a very
bitter taste in many mouths.
I was reminded of this just the other day when I was chatting with a small
independent dealer who does good business selling Sigma lenses. He asked me
what I was testing and using these days, and I replied the Sigma DP2M and
DP1M, and I told him how impressed I was.
He just shook his head and said that he was so angry with Sigma that he
wouldn't consider carrying these cameras. Apparently when the SD1 was
introduced Sigma's reps put a full court press on dealers to get them to
carry the camera. This was back when it was to retail for some $8,000. The
dealer said that he very reluctantly agreed to stock one, not wanting to
piss off a major supplier. But, the camera sat on the shelf month after
month after month, and eventually was (in his words) "given away" for well
below cost, simply to clear it off the shelf and out of inventory. The idea
now of taking another Sigma camera didn't leave a very good taste in his
mouth, he said.

Who is It For?
Make no mistake. As I've written, like its sister the DP2M this is not a
camera for dilettantes. But, if you are willing to forgive (or at least
accept) its foibles (crap battery life, slow file writes, annoying raw
software) you will be rewarded with some of the most amazing image quality
short of medium format or sheet film.
This has been brought home to me as I've worked with both cameras for a
number of weeks. For the first time in a long time, I find myself shooting
subjects simply for the pleasure of seeing what they will look like in
prints. This is the type of photographic satisfaction one gets from 4X5"
film on large prints, or a medium format back with a high resolution sensor.
The only real difference is that in this case instead of requiring film,
darkroom time or lab costs, or the high entry cost of MF digital, a sub $1,
000 camera + lens combination can deliver a similar result in appropriate
circumstances. The only real technical limitation is that the DP1M and DP2M
are limited in print size to what one would get from a 24-28MP camera; let's
call it about an 20X30" print. At any print size smaller, assuming the use
of ISO 100 or 200 and high enough shutter speed or a tripod, I would
challenge a gallery print comparison with just about any other camera lens
combination, and yes, I'm including a Nikon D800e with top glass or a Leica
M9.

The Competition
As I see it there are two competitive cameras to the Sigma DP1M and DP2M.
These are the Leica X2 and the recently announced but not yet shipping Sony
RX1. The Leica has a 16MP APS-C sized sensor while the Sony has a 24
Megapixel full frame sensor. The Leica lens is an f/2.8 35mm focal length
equivalent while the Sony has an f/2 35mm lens. Both camera do have AA
filters.
I have used the leica X2, though not reviewed it here. Operationally it is a
much superior camera to the Sigmas, but not when it comes to resolution and
over-all image quality. Both Sigma's trump it in this regard, big-time.
Also, at USD $2,000 for the X2 one could buy both the DP1 and the DP2 for
the same amount of money and have greater lens diversity as well as a backup
camera.
The Sony RX1 is, of course, a complete unknown at this time, in terms of its
handling, operation and especially image quality. But at $2,800 it had
better be quite spectacular, because that's an awful lot of money for a
fixed lens camera, regardless of its capabilities.
Living with the DPM1 and DPM2
I can live with the poor battery life. I can live with the slow write times.
I can live with the wobbly image on the rear LCD. The image quality makes
those travails worth accepting. What I can't live with is the horrendously
annoying Sigma Photo Pro software. This is sub-par, under featured,
underpowered, slow and buggy. But at the moment, it's the only game in town,
because Sigma isn't working with third party raw software companies to make
support possible.
I have therefore written the following open letter to Sigma's CEO. I don't
know what effect it might have, but with 1.4 Million monthly readers on this
page, maybe, just maybe.....
