DPMerrill real world comparison to A7r

[Addy101]

While most of your comments that I have read before are easily understandable and well-thought I out, I don't what you mean by depth.

If it refers to color, the Sony images look like a Velvia-simulation in some LR plugin. One of the things that is really cool about Foveon color on the Sigma is that it captures both dull and lively colors with equal 'presence' in the same frame.

On the other hand, if depth refers to resolution and microcontrast, it sounds like your comments about the city would suggest a marked advantage for the Sigma. I did pay attention to the city, and I thought how muddy it looks in the Sony image. Then my gaze travelled over to Mt. Fuji, and the difference was compelling. The Sony is hazy placeholder on the horizon, the Sigma is living breathing mountain that towers over and away from the city.

To tell the truth, when I first opened the website, I thought for sure that the Sigma image, which has higher resolution, finer detail, and to my eyes better color, was from the the Sony (such was the hype around that camera's 36mp sensor).

It might very well be the color or rendering of an program that I am looking at. I don't know. However, clicked the pictures and I know what you mean. Looking at these and thinking some more about it, it seems that the PP is very important. He says "The JPEGs with this post were rendered from RAW files with minimal post-processing" but doesn't mention what program he used. Might be very important to understand the difference.

If you take photos of still leaves and such in good light the Sigma is great, but it's not a camera that can be used for much ...

The Merrill-line is useful for anything that you can use its peers for - i.e. medium format cameras. Think back to the film days - you can use the Merrills for exactly the same as Rolleis and Hasselblads.

But unlike the previous generation DP-cameras it takes very sturdy hands and/or very good light to shoot this without inducing shake. This is not a Bronica RF645 or Fuji GA645zi you can use on the go unless the light is very bright (or in a studio).

I only own the DP2M but no digital camera I have ever possessed (quite a few) gives better IQ.

I have always been impressed by the image quality that comes out of Foveon sensors, but I also think very little of that unique quality comes through at most viewing sizes. They are marvelous technical accomplishments, but at this point, I just want a camera where my RF lenses work and have the same focal length as they do on film. Cell phones are easily 'good enough' for low iso static subjects at web sizes, splitting hairs over pixels is starting to seem really silly. All the pixels look amazing - there are no bad choices.

I cannot agree with this.

The physical size difference between 120 film vs APS sensor manifested itself in more than just resolutions and details.

For example, depth of field. Are you saying I can create images with the same look as a 6x4.5 with f/1.9 aperture with a DP Merrill camera?

If Sigma ever created a large version of their Foveon sensor, then we can compare apples to apples.

Like an 27" iMac and an iPad mini?

Yeah, I've never really agreed with this claim. Medium size is really so much more important than resolution when it comes to the medium-format "feel." Though, I do believe that the tonality I am able to get out of the Foveon sensor are a bit more impressive than what I have seen through Bayer chips.
