Perhaps not, its not a camera you'd really want to use the jpegs out of, and honestly I don't even like shooting it handheld, plus the speed of writes etc is bog slow so you'd be left standing there frustrated.

Its really a landscape camera or at least a camera for a landscape minded photographer IMHO.

If your used to working with a tripod, take a few carefully composed exposures, and then are used to spending a lot of time working on the image doing countless revisions, layer blends and color tweaks etc (regardless of what its shot with) then it should fit into the workflow nicely.

The results, when the subject matters suits it, are worth the effort, and at $800 new these days, the prices are to where I can personally justify keeping one around even though I admittedly don't use it all that often. For the cost of just 1 midgrade lens its just a special tool.

Lately I've been comparing it with my Fuji XE-1 (w/ 35mm).

Xtrans vs X3 for foliage detail....

Millsart have you seen this posting from Amin Sabet on fujixspot (with DP2M and Fuji XE-1 raws)

http://www.fujixspot.com/f24/full-res-zeiss-touit-32mm-f-1-8-sample-photos-1287/

These 25mb files do hold a lot of detail. They are not far behind the DP2M. I did run them through C1 and SPP. Amazing considering these samples. I do own a DP2m myself BTW.
I did read your remarks regarding the 100s. "What I don't find I'm getting from the Fuji's, regardless of lens choice, is that true pixel level clarity of the Leica's, or the Merril's (my "M" cameras of choice these days)."
The Zeisss Touit might contribute to the difference between the 100s and these files.
Just curious.

I did see those comparisons and they are pretty much in line with what I've been seeing between my 35mm 1.4 on the XE-1 and the DP2m, other than a little closer in focal length.

The 35mm, as is the Zeiss it appears, are both really good sharp lens, which is reasonable to expect at the price points and moderate focal lengths.

They render good sharp detail as well, but areas where I can see some differences are the edges of the frame, as the Merrill is as sharp in the center as it is the edge, and also for more distant details. I guess it maybe just comes down to the sensor and different wavelengths of light perhaps, but the Merrills can this ability of just making everything in the entire frame sharp, if you give them enough DoF that is.

In the samples, just look at some fine detail in the background such as tree limbs. Even with less focal length advantage, the Sigma files are finely detailed where the Fuji kind of get a bit mushy.

Its not even an XTrans thing though as I can see the same thing with my Sony RX1 which has a real resolution edge with 24meg and a great lens, plus normal bayer array. Every bit as sharp if not sharper for closer subjects, but not more distant ones.

I've done some testing shooting some things like houses across a field and the differences are always surprising to me how much better the Sigma does, which is really why I keep it.

Of course in most situations one probably just cares about the main subject, but for those special landscape applications where you might want, say a foreground river, and then mountain peak in the background both to be really detailed, the Merrill is a great tool.

I'm again not sure exactly what gives it this advantage, if its perhaps different wavelengths is a theory I have, as I do find the cameras can cut through haze pretty well, and you do have full resolution of each channel, but whatever they do, it works quite well.

Forgot to add that for what I use the Merrill for, stitching, the across the frame sharpness really comes in handy.

If you look at the samples of the wooden sign in front of the lake, while all three images have great detail of the sign itself, if you look across the frame along the area in focus, the Merrill shots weeds or grasses are as finely detailed at the far edge as they are in the middle. The Fuji shots get a good bit softer, and when stitching, having no distortion or softness to account for helps for a better overall end file.

Again though, realistically if the subject was the sign, then its a moot point and any camera/lens delivered a fine shot, but there are some differences you can find depending on what your end usage of the file is.

I dont understand this comment. The buffer on the DP2M is quite deep and allows you to keep shooting after each shot. I find the camera to be fast enough to shoot most situations, far beyond landscape. Rarely do I ever hit the buffer limit and that is only when shooting many shots for stitching later.

The buffer on mine is only 7 raw images, and it takes the camera about 2 minutes to clear the buffer after that, so in my book, that is bog slow, and also not remotely deep.

Are you just shooting JPEG ? That perhaps makes the buffer work better, but I find the jpegs to be pretty poor, or at least not remotely as good as the raw files can be. I use jpeg with my Fuji's and Sony's and they turn out pretty good, but the Merrill jpegs always have poor color, higher noise and aren't nearly as sharp.

Unless of course there just is something wrong with my DP2m because as I said, I don't for the life of me understand how you can say its got a deep buffer when it comes to shooting RAW

Nope, I never shoot JPEG. I agree with you, this is a RAW only camera.

7 shots is a very deep buffer for me as I virtually never, ever hit the maximum.

7 shots would be fine if it could clear the buffer at the rate of most any other camera, but each file takes 20-30 seconds of the activity light, so it can be writing (and unable to do anything) for 2 minutes or so when the buffer is filled.

I find this somewhat problematic as I often will do an exposure bracketed stitch, so basically after shooting 2 just positions, I've already got the buffer full, and then have to wait to shot the remainder on even a simple 3 frame pano.

Granted the latitude and DR is pretty good so its not as if every image needs bracketing, but when you use it, your stuck with a slow camera.

Also each RAW file is huge, 40-50meg so the camera is moving a lot of data, so I guess its not "slow" per say in the pipeline, but the net result is long write times due to file size

Yes, I agree, the DP2M isnt really slow, it's just moving massive amounts of data. Any other camera moving that much data would be just as slow.

I have never done a bracketed stitch so your situation is unfamiliar to me. I can see how you hit the buffer really fast then.

Still, I find the stitched images that I can make with the DP2M so impressive, that if i had to wait 2 mins to get the shot, that would not be a problem with me and not even something I would think about. It would just be the "cost of doing business" to get such an impressive shot.

It does stitch better than any camera I've owned, on account of the nearly flawless less, but, with some scenes, such as when the light is changing quickly, either due to a setting sun, or clouds about to obscure the sun etc, that delay in waiting for the camera can prove costly.

There are things that you just can't do with a pano, such as breaking ocean waves, just isn't possible to blend (unless you do a super long exposure at least) no matter how fast you go, but usually if your pretty quick shot to shot, even scenes with people in them etc will stitch together without much ghosting.

Its when you've got that 2 minute wait that a lot can change from the last frame you took, such as the overall light level.

One solution if your using a head with indexing rotor is to just do one full pano at one exposure, and then change exposure to account for a darker foreground or what have you, and then shot that as its own pano, then blend the two pano's together.

This works as the indexing rotor lets you go to the same positions each time, but with shooting using just a ballhead, your going to have alignment issues.

I"ve never done any of this! Care to post some of your work that illustrates such? Sounds very interesting.

Nice capture sculptormic.....I really need to try stitching. I would imagine you have a pretty wicked file when you're done, something that could be printed LARGE.

So I've just got my DP2m last week, at last...

I got the impression flash compatibility was going to be an issue, but all my Nikon strobes work perfectly, be it in M mode, and with SU4 mode engaged, I can shoot a 3 strobe setup without a problem.

On a more technical note, is the cyan/magenta lens shading cast influenced by UV and/or IR light?
Seems like my outdoor shots are more prone to colour shift. I'm not entirely sure how the colour cast should behave with this camera/lens set up. I shot the blue sky, neutralised the blue colour at the centre, and observed what seemed like a unsymmetrical colour shift.

[EDIT]

Who prefers the Monochrome mode in SPP over the B&W tool in LR?
I find I get smoother images in LR4 converting a colour image than from the Monochrome mode in SPP. Well, anything but a neutral or a blue filtered image in SPP is noisier than the LR conversion.

BTW, I shot a scene with a red filter, and converted it to B&W in SPP, and I must admit it works very very well.
I'm still waiting for my step up ring to use 52mm filters.

Also, I was under impression that it takes forever to write images to the card.
A 7 image burst (RAW at full res), from the moment of pushing the release to when the red light goes off for the final image, takes 41 seconds. I've read others are experiencing this to take up to 1:30min or longer. I'm using a 16GB Sandisk Extreme 45MB/s card.


Anyways. Some pics...

I posted this full rez TIFF on Flickr because I think it shows the breathtaking resolution and '3D' capabilities of this amazing camera. I think it's about 56 MB. From Karnala forest reserve nr Mumbai, this morning. Unfortunately, you need to see the full res image to get the effect.....
