@Boris,

Did a famous wall shot for checking centre/edge/corner sharpness.

I did 4 series, two manual focus, 2 auto focus. Two focus in centre, two focus at halfway towards corner.
One in upper right corner, one in lower left corner.

Distance around 2 meter.

Result: f/5.6 is sharpest and most contrasty in centre, edge and corners here.
So the end result might change a little with the distance. The result is very even across the frame. At f/11 clear softening starts due to diffraction.
Saw also a bit light falloff that has disappeared at f/5.6. There is also a slight barrel distortion that can be corrected
...Show more

In my opinion the difference in sharpness between f/4, f/5.6 and f/8 is neglectable, so you can choose between these apertures based on prefered DOF. But I will try to avoid f/2.8, f/11 and f/16, if possible.

Thank you Millsart and Herb for your replies regarding NEX / Sigma comparisons. I think I will continue to sit on the sidelines for now and enjoy the thoughtful discussions and amazing photos on this thread.

I'd suggest ordering one from Sigma USA, give it a try, and see how it works both as a camera for your needs, in addition to what type of IQ you can get out of it, and then decide if its a good fit for you, or if the results of your NEX7, and its better usability suit you better, if so, return the DP2M to Sigma for a full refund within 15 days.

Its such a unique camera you really have to try it hands on IMHO

Really nothing to lose except $7 for shipping, and the piece of mind of actually knowing if it would or wouldn't make a real difference in YOUR own photography is pretty priceless.

I, like you, was seeing some pretty impressive photos from them, but its always hard to judge just from the results other people are getting, as their ascetic taste, workflows etc are naturally different than mine.

I've seen amazing results from various brands of camera's I could never match in my own usage, and I've seen poor results that I felt I personally bettered in my given time with a respective type of camera.

I've also simply hated the handling of some cameras that other people though worked fine, and had no issues with camera's others just cant deal with. DP2M perfect case is point, the design and speed of the camera is totally fine and doesn't get in my way in the slightest, no doubt because of the way I work with it. Others could want to smash in after 5 minutes.

I usually shoot in Av or M mode, and the big chunky dial around the shutter controls aperture, the big 4 way controller left/right buttons control EC, up is AF/MF toggle ad down is drive mode. There is then a QS button for ISO, WB etc

In the field this is all the control I need. Quick and easy to dial in some EC etc, even with gloves on. Your not going to hit the wrong button.

Your not going to wade through a bunch of menus to find a feature

Your not going to have to try to figure out how the camera got put into face detection pet birthday HDR minature mode and why that is limiting you to auto AF point selection of auto ISO

Its just really simple and basic

If you want AEB its an assignable button push away, and can do +/-3 EC steps

If your doing a pano and want to turn off AF, its as simple as locking focus, then hitting the af/mf button and then shoot each from in your pano.

Stupid simple if you will


IQ too, is something you've really got to play around with, shoot it side by side and pixel peep a little, see how corner sharpness, color, fine detail etc renders

One thing I notice with the files is more depth and clarity, in addition to just resolution.

I can have an image side by side on my 27" monitor and the DP2M files just seem more three dimensional usually.

Got to see if that IQ difference equates to $1000 to you though, its a fair bit of money after all. We all want great IQ, as I don't know anyone who sets out to get a soft lens etc right ? But, there is only so far I think we want to go.

There is a reason we all don't drop $4.5K on a 50 Lux ASPH no matter how good it is. There just is a point where the bang for the buck falls a bit short, even if we can afford the bucks. Diminishing returns.

DP2M though is pretty unique in that it can take you, in some cases, far, far up that slope of diminishing returns, and yet do so at a fairly reasonable cost.

I wouldn't buy a 50 Lux any more than I would pay $5k for a DP2M, but at $999, pretty tempting, just as if someone would sell you a 50 Lux ASPH for $999, might have to reconsider the whole bang for the buck then. Suddenly the bang per buck ratio just went through the roof!


Thats really what happens when your looking at DP2M files. They look so good, but the other part of your brain is saying " do I really need this, how much would I use it" etc

That "sensible" side of the brain though also then thinks, "well, $999 isn't that much, I've certainly spent far more on other gear, I could always sell it later if I get bored with it" etc

Sort of leaves you, as with most users, of the opinion, that the camera is pretty unique and brings a different kind of fun to shooting, a more craftsmanlike approach, and if you can live with the tradeoffs, the resulting IQ, while not priceless, seems worth $999.

Sandy Crane,

Michael Reichmann of Luminous Landscape fame wrote down the essence about these Merill's for me.

One just wants to continue shooting just for the fun of how anything will look on the photograph.
Everything will look new and fresh compared to all other camera's so far used.
Basically this is for me one of the core reasons I make pictures. So with the Merill I am getting back to the essentials.

Will you show the un-boxing after the delivery of yours?

Just kidding. We almost forgot the Nex 7 (with a Sigma lens) can also make really nice and sharp images.

Are those neon-yellow animals fatty cows?

Love the detail of the sheep shot posted above though. And the image as a whole, nice comp too.

Thanks again Millsart and Herb.

My nain problem is I never really liked the NEX-7 until I mounted the Sigma 30 and now I feel committed to wring it out before moving on.

I must say I am intrigued by a little box that takes astonishing photos. I am not overly impressed by face recognition or automtic HDR or much of the other bling that camera manufacturers have thrown our way. While I certainly appreciate the 400 photos I can get on a charge while traveling I somehow am attracted to the discipline that 40 shots demands.

So, I had the oppurtunity today to take the NEX to a nice setting. Tomorrow I'll review the photos and ask myself if they are "good enough to be better"? I am not so deluded as to think the main limitation in my photos is the ultimate quality of my equipment.

We'll see.

Here are a few photos from hiking with my DP2M today, taken under clouded-in lighting (B&W photos taken through 091 "dark red" filter). I got 88 shots from two batteries (and still showing "full" for the second battery on the camera).

Color balance in SPP was a struggle (for the non-B&W shots), since I didn't have a color calibration target or previous experience for adjusting "fogged-in" white balance; SPP's "Overcast" WB setting was definitely wrong for this situation (sickly yellow-green cast and oversaturation), so I was mostly working from manual adjustments from "Auto" WB.

I'm happy to find that the camera's auto-focus and exposure metering seem very reliable; in fact, for exposure, I've had several instances where I dialed in an exposure compensation (thinking I was smarter than the camera; based on habit from adjusting for scenes with my 5Dc), and had to cancel it out in SPP.

I'm really enjoying using this camera.

It's been fascinating to read the posts here about the new DP1/2Ms. Frustrating too because I have one but haven't been able to get out for the past weeks.

This problem came up and I wonder if anyone else has found this in the software-- heavy bands of green and pink. Can't make it go away--other images with the same setting are OK.

Nice shots, looks like you nailed the WB

I've not had such great luck with my red filter. Images come out a little soft with it for some reason, not sure what the problem is. Nice thing with the Foveon of course is that your getting 3 full rez layers of color info so its a fun camera to do some conversions with.

That's surprising to me; maybe you're more picky about sharpness than I am, but I haven't felt my red-filtered images are coming out soft at all. Can you post an example? What filter are you using (and does it have a big fingerprint in the middle )? Below is another image and 100% crop. My B&W processing procedure is:
- In camera: same settings as for color photos; camera seems to choose correct exposure through strong filtering.
- In SPP: "monochrome" white balance, sharpness -2, chroma NR -2 (haven't checked if this even makes a difference), luma NR -1 or -2 depending on how picky I feel about the slight banding that does appear; lower luma NR does improve fine detail sharpness (default 0 can nearly obliterate some fine textures). Pull down exposure to preserve full desired highlight range in exported TIFF-16.
- In Aperture: Sharpen 1.0/0.5; adjust exposure/curves to liking
