Hello everyone,

About a year ago , I bought a DP2 X. I own several other digital cameras but as an avid street photographer , I was attracted by the unique ability of the Dp2x to function as a very discreet tool for street photography. First , the 40mm focal lens equivalent is the perfect walk around lens and my favorite focal lens for street photography. As Sean Reid wrote in his excellent reviews on the Dp2 and DP2s , the 40mm choice made the sigma DP2 the worthy digital successor of the Rollei 35 ( a film camera which despite its names got mostly produced with a 40mm lens).

the Sigma DP2X has a mediocre LCD , only offers 5MP files making large prints problematic but had the best design for street photographers who wanted to use an OVF and snap focus for discreet photography

and THEN NOW Sigma comes with a DP2 M which now features a very rich 15MP sensor , a current high def LCD and even the possibility to shoot RAW+JPEG ( allowing B&W photographers to review images in B&W while keeping the RAW files)
so all seems that we have only reasons to rejoice , yes ?

ALAS, Sigma in one of its surprising and ill-conceived moves has chosen to cripple its camera by removing its two most unique features for street photography. First , the new SIGMA DPM are doing away with the unique and outstanding wheel for snap and manual focus :(( . This could have been compensated by having distance markings on the lens barrell . But no such luck.

To make things worse, SIGMA decided to change the focal lens from 41mm to 45mm ( a poor decision IMO) making the current OVF obsolete . I am not aware of any 45mm external finder available today and SIGMA does not seem to make one available for the new DP2M.

As a result , the new DP2M would be restricted to LCD only for composing and manual focusing . a VERY, VERY bad choice which is going to alienate a part of the current DP users and make it very difficult to compose and or manual focus in bright sunlight

I have made some great images with my Dp2x which would have been almost impossible to make with another camera. if someone had told me a few months ago that Sigma DP2x successor would bring a sensor with 3 times as much resolution , with a better LCD and a RAW+JPEG option , and that I would have ZERO interest in getting one , I would have not believed it.

Sigma seems to have an uncanny ability to develop some products with unique features and yet preventing those products from being as popular as they could be by making some unreasonable decisions in terms of pricing , availabilty or design..

Feedback or comments welcome

I think the new sensor is slightly larger so the view angle should be about the same.

Since this cameras claim to fame is the resolution, getting the focus perfect makes sense. Maybe they didn't think anyone would be content with almost in focus using a manual guess.

If I had designed the camera I would have made a hand grip in the form of a bulge opposite the lens and used the space for a larger battery.
 
Note that the SD1 and DPMs have a 1.5x crop sensor versus the 1.7x one in the SD15s and DPs.

While this doesn't address all the things you're unhappy about, it makes the focal length change less of an issue. The FOV will be similar in the DP2M to the DP2.

Harold,

Comments? It's a little early to be whining about perceived issues with a camera that hasn't been released yet. But hey, it's the internet and everyone does it...

I don't think the difference in focal length will be much of an issue for framing with an OVF. In fact, I'd worry more about parallax issues (the lens isn't centered under the hotshoe anymore). Similarly, you may (not sure) need a plate for panos.

After seeing SD1 prints in person, this camera may just be incredible. What I really hope is that operating it is a joy and not a chore. That focus is actually fast and easy to use. That the buffering doesn't drive you crazy. That you can see the LCD in different conditions. If they execute well on these, Sigma may have a hit on their hands.

But I'm going to wait until the thing is actually out before praising or damning it. I will say that it's likely to create beautiful prints tho...

SIGMA DP2x Firmware Ver.1.01 download
2011.7.22

I guess we have to wait that the actual DP-M cameras com out to evaluate pros and cons vs DPx cameras.
At any rate RAw+jpg is available on dpx since last july.
Unfortunately it is not for my dp2s :(

From Sigma website:

Sigma Corporation is pleased to announce that firmware Ver.1.01 for the DP2x is now available for download.

SIGMA DP2x firmware [Ver.1.01]

Benefits of the firmware update

RAW+JPEG simultaneous recording is incorporated
Functions related to focus frame is enhanced
A phenomenon which produced noise under certain conditions is fixed

SIGMA DP2x firmware Ver.1.01 is available for download at the following site.

Hello Britton

I am aware of the larger sensor but if my info is correct all the info was given in 35mm equivalents so while the dp2s and X had a 41mm equivalent , the dp2m is 45mm which is different enough to make the OVF obsolete :((

Harold,

Hello Jim

I do not understand your comments . My comments are not about image IQ or things which are not known. They are about physical specs that were changed from the dp2s and dp2x

so I think it might be interesting to see that the dp2m seem to be aiming at very different users

How do you manual focus with an OVF? doesn't make sense to me at all. I never focus by the metering marks. Too unreliable.

Besides 41mm vs 45mm, I cannot really see the big problem. Your 41mm OVF will frame slightly bigger, but I have not seen an accurate OVF anyway, so I really don't see this "problem" either. Something to get used to.
 
If I had designed the camera I would have made a hand grip in the form of a bulge opposite the lens and used the space for a larger battery.
Why would you wish to make an ugly camera? What purpose would this grip serve?
 
Most SLR cameras have a bulge to grip with. I wouldn't call them ugly. It's a matter of taste for sure.

Longer battery life is something people will probably want with this camera. I am guessing of course. Two processors might just eat some power.

Adding a hand grip with a large battery would not increase the overall dimensions so it would still be a coat pocket camera.
 
I've discovered that accessory grips are unnecessary - what you need is a half case.

I have them for my G7, G3, 450D and had them for my e410 and GF1. They transform gripless cameras and cameras with built in grips alike because they make the grippable area fatter, are slightly squashable and have edges you can grip too.

Aren't most VF pretty approximate anyway? You are kind of guessing a bit with optical tunnel viewfinder (don't forget parallax). All you have to remember is that slight increase in focal length will very slightly crop your FOV within the framelines.

Irritating but relatively minor and I would imagine easy enough to get used to. Some viewfinders (G7 for example) only show about 75% of the FOV!).

I think you are missing the point . at short distances like 2 or 3 meters , it is one thing to see less than what is captured , it is quite ANOTHER thing to see more , meaning that you would think someone is being captured when it is not

I know of no one who is comfortable with this arrangement and it is frustrating since sigma got it right with the previous dp2s and dp2x

It wouldn't increase the maximum size but it sure does something to how easily it fits my jacket pockets. I had a Sony V3 and always wished they didn't change the design from V1 by adding that second bulge.

What are you talking about? The hotshoe is above the lens. No parallax issues there...

Not for a DSLR, but for a mirrorless they are. Like the Panasonics.
Longer battery life is something people will probably want with this camera. I am guessing of course. Two processors might just eat some power.
I'd rather bring 1-2 small batteries if needed. I notice a big difference between my DP2 and the DP1s in terms of battery usage. So I'm not too worried although the DPMs will need more process power, writing time and LCD will use more power.
Adding a hand grip with a large battery would not increase the overall dimensions so it would still be a coat pocket camera.
No it would increase the overall volume and that will be hard to put in a pocket. Easier to fit a triangle than a rectangle in a pocket.
 
Ahhh, that's what happens when you rely on a faulty memory. I thought the shoe was still centered! Thanks for pointing that out!! I wonder where the tripod thread is (hopefully underneath the lens...)
