    Note just how good the DP2 is at retaining detail in the windows. This is not an HDR shot.

    Quentin, Very nice interior pano shots. I agree on the DR capability of the DP2M and I also find that I can get by with much less PP fiddling. The images just look great right out of the raw converter.

    Hallo here to all, Allow me to just some modest sunday-remarks, not quit fresh (who knows when that will be...). Thats a fantastic picture Quentin(!), and for an architect, its funny to be able to look at all those different craftmantechniques you are using over there with lead, the way to keep it in place, your way to make sliding-windows in the past(the danish way are better here), etc.
    And the church-interior, wonderfull. But even thought "PTGui" and "Smartblend plug-in" tells me absolutely nothing(confession-time...and probably never will..), but allthough that fact, my eyes are allowed to be comforted and pleased when they look at quality and artistic expressions...and that's a nice thing

    Hi Thorkil

    Thanks, and the questions I think I have answered for myself are as follows (reinforeed by Carl's excellent shots I hasten to add)

    Q. Can the DP2M be used a a substitute for medium format by using stitching?

    A. Yes, it can. Possibly without stitching in some cases.

    Q. What are the issues?

    A. green cast in shadows / corners sometimes (correctable, but a nuisance); stitching needs some work to get right.

    Q. How about dynmaic range?

    A. Early days, but it might better the H4D-50, incredibly.

    Q. Overall, how close to medium format is a stitched image from the DPM?

    A. Check for yourself - here is a link to a shot taken with the Hasselblad H4D-50 and 50mm lens (I used the HC-50mm mark 1 - which I have since upgraded to the much better, sharper edge to edge, Mark II)

    Re: Sigma DP2 Merrill shots

    Hi Quentin
    Yes, its very, very good. Its not quite up in the level from my Hassy SWC, Velvia 50, scanned at a Imacon in the past, and enlarged by a Durst (I guess it was, digital to analogue) at glossy photopaper at 100cmx100cm (far better/sharper than if printed). But it is sufficient close. And for my purpose its what I only could dream of, I think. So decision to let the 800E go is made (at least at 99,99%) because realistic seen, a 800E is too bulky, any DSLR is too bulky for me to realistic being used more than 5-10% of the photo time. The other time might be a DP1M + some P&S cameras(and perhaps one of them should end up in a RX100 because of the resolution and IQ). And it sounds promising too with the high Dynamic range.
    Perhaps I should learn to stitch, but realistic seen I will have just to go with the 28mm.
    And it will be interesting to see if it can be used until a certain degree as a modest street camera too.

    Re: Sigma DP2 Merrill shots

    The perfect system for the minimalist photographer - Sigma DP2M + DP1M. I think that is where I am heading, if the DP1M can match the DP2M quality. The Fuji XP1 and NEX7 systems will be gone next week and I will keep the OMD for casual and telephoto needs for awhile. The serious landscape work will be done with the DPMs.

    David,

    I tried using a Hoya R72 and got nowhere. No IR response that I could see in a shot of some green foliage in bright sunlight - just very dull, underexposed grays. No Wood response at all. Suggests that IR is essentially completely blocked out with whatever cut filter they have on the sensor.

    Re: Sigma DP2 Merrill shots

    Thanks Carl. That's a pity as the resolution would have been nice to have at IR. Should be a lot better than a Bayer array sensor I imagine. I did find instructions on how to remove the IR filter glass from a DP1, so it could probably be done on the Merill too, but rather a drastic step. Very intrigued by the DP1M and am watching this thread with interest.

    Re: Sigma DP2 Merrill shots

    We walked this afternoon in the gorge just below our house. Very dark and muggy with occasional sprinkles. I used the DP2M on a small tripod with 2 sec timer for shutter release.

    The "Green Lagoon", a small pool in the creek at the point where the gorge trail begins. This shot was processed in SPP using "landscape" color mode which appears to emulate Velvia. I decreased saturation about -10, but still too much color. Most of my shots are processed in SPP using "neutral" which occasionally needs a bit of a saturation boost.


    FULL SIZE

    A two shot stitch in the gorge. Still extremely low water and near drought conditions.

    Great review - but what I can't understand is why he didn't use the Sigma 30mm on the NEX 7 - isn't it the same one in the Dp2m?

    Also, I think to those who are waiting for ACR support - if there's any lesson to be learned from the X Pro-1 experience - when it comes to "unconventional" sensors, I will stick to the method that yields the best results, even if it's a pain!

    Re: Sigma DP2 Merrill shots

    There does seem to be a consensus emerging among those who have used the DP2 that this camera is the metaphorical game changer.

    Perhaps the more interesting question now is where do Sigma go from here? Can they produce a 30mp x 3 Foveon sensor in a new high end product and do they want to do so?

    What I hope they will do first is to make a 50 or 60mm DP3. Carrying 3 small bodies when I travel is easier than 1 larger body and 3 lenses, but I do need a longer lens for portraits etc.
    I don't care what gear I have.

    Re: Sigma DP2 Merrill shots

    I hope Sigma make their SD1M SLR more attractive and useable. In his review of the DP2M Michael said they had improved the sensor over the SD1 that he tested.
    Sean Reid actually was actually quite upbeat about the useability of the SD1. It is now down at the $2k level.
    I'm going through a phase of enjoying more bulk in my life, with my K5 and K-01. It's good to get away from those tiny cameras, with tiny buttons - invariably you still have to carry a bag for them.

    Wow. I just browsed very quickly at the LL review of the DP2 Merrill shots here:
    Sigma DP2M Review

    Scroll 3/4 down the page to the comparison against the Fuji X100, a camera I always thought had good balance, however, compare middle right of the photo of leaves in the shadow region.
    I see so more micro-contrast and dynamic range. The details are just fantastic, really blown away by the DP2! Anyways just saying

    The Sigma E lenses are quite different from the new lenses in the DP Merrill cameras. Links below have lens descriptions and MTF charts for each.

    Thanks for this - I was under the impression they were the same, which would explain their low cost for the E lenses.

    Arca plate for DP2M??

    For those that are using tripods has anyone found an Arca plate to fit the DP2M yet? Thanks!

    I don't know of any Arca plates but there are a few from RRS that work. I'm currenty using a RRS B-6 plate that I bought a few years ago for my Panasonic G1. Not a perfect fit, but works just fine on the DP2M. They also have small, generic adjustable plates that were intended for P&S cameras.

    I am very optimistic. I actually did studio tests with Dick Merrill at Foveon with 1Ds vs. SD10.

    Food photography, using the DP2M plus dedicated close-up lens AML-2 (which has just arrived)



    Not the ideal choice, but it works.

    WOW, and Yum!

    I would love to see what a focus stack do from this camera!

    Re: Sigma DP2 Merrill shots

    DP2M is looking great although mostly as an outdoor camera and only upto ISO 400 (after which color and banding creeps in very quickly). Although I know very little about the foveon X3 sensor, it seems extremely well suited to high MP camera with great detail, good DR and with the good lens to pick up micro contrast detail. I'm excited about the future once there is more versatility in the range, perhaps a high quality zoom lens, but I already like 45mm effective crop. Once they are more in line with today's ISO, say good upto ISO 6400, I would be game. The daytime photos are simply beautiful.

    Shows a lot of detail and images are very sharp (-0.5 sharpening in SPP and 0.0 in LR):




    >I see so more micro-contrast and dynamic range.

    Lots of micro-contrast is there. Not sure there is a very high dynamic range. In high contrast scenes the shadows get noisy at ISO 200.

    Question: Does Auto ISO really start at ISO 200?

    Uwe

    Try exposing for the shadows. this helps with shadow noise and there is good headroom to recover highlights

    Re: Sigma DP2 Merrill shots

    How much overexposure do you think it can handle. Don't forget we have stronger sun here than in the UK and that very often :-)

    Question fro Quentin: Does Auto ISO really start at ISO 200?

    Re: Sigma DP2 Merrill shots

    What is the optimal smallest/lightest tripod possible for the DP2M? Any suggestions?

    I'm using a Gitzo 1027 MK2 carbon fiber tripod, 1.7 lbs, 48 inch max height, 16.5 inch min height. This has been my travel and hiking tripod for the past few years and is great for small cameras. I don't know if it is still available, but there is probably an equivalent newer model. I have the Gitzo 1176M ball head with RRS B2 LR clamp and small RRS QR plate on the DP2M.
