Everyone starts from an egg then becomes a chic then a chicken and so on .
So all have the same start.But the vision makes everyone different, it also defines your level of satisfation and even determines that you would stay where you reached or pursuit for a better.
Digital photography is a result of the universal science: Precise Mechanism, Optics, Digital Electronics, IT ...So if you want to make something your own , you must know them.Internet has all that for you and me, and that is always have someone did something like that before, waiting you do it your way and the tree is growing.
OK now return to reality : Sigma SD1 has many performance shortages, but not in PP processing, especially the sharpness.Foveon is the sole sensor provides you a pixel size colour sharpness, while other part of the world makes it in atleast 3 times larger ( I do not mention the absolute pixel size measurements, those are different from each manufacturers) .Most of my pics I don't do PP much, and SPP is more than enough for me.Sometime I tried LR or PS but nothing better, so I rerurned to SPP, maybe I need some special effect sofwares in near future but not right now.

Yesss, I am considering the mass, near 1kg with the mount and the Chinese helicoid seems weak in long term using, not shoot with it yet.Hope tomorrow, after some small fixings.

@Inglis: nice tulip, but as usual Mamiya 120 f/4 gives much contrasty look than this( you can find M120mm images some where on this thread ).I don't believe in SB optics much.

Imo ... you should remove the Speedbooster.
You've got great contrast being produced by the nice tight light rays coming through the the M645 120 ... then you're taking those rays and re-routing them for a contrast degrading result (imo). It looks like you got some soft light (read low contrast) to work with here. Further lowering contrast via the SB isn't doing you any favors when trying to pick up already delicate details (contrasty subject/light, the SB impact is likely not as much of an issue) to my way of thinking.
Played with it a bit and came up with this ... includes a curves adjustment LAB L channel, contrast and highlight, some desaturation and USM mostly. Let me know if you'd prefer I pull down the pic, but it is offered up for some perspective. Likely better results are attainable from working off the raw of course.

Rustybug, I have been reading your comments on the Mamiya lenses as well as Contas, together with the 49 page archived Mamiya(MF) on Digital Thread with Jim Schemel's contributions. Really thank you all for your discussions. I realize I have a learning curve here and thank you for your suggestions here and will follow up. The Rhinocam also interests me so there are many possibilities. So thanks all and I will read up on these things and move forward! The Mamiya lenses are so affordable and they provide such interesting visual perspectives. Now if I could only understand how Hugin deals with the Mamiya 645 image circles! When I enter 55mm for the lens, and 1.5 crop for the camera, the stitched images appear to fall outside the normal projection choices, but that is another matter . . .

@Inglis: nice church, very good M35mm.Nex somehow likes Foveon in low frequency noise, I always shoot RAW to eliminate the noise.
Here is Mamiya RZ67 50mm f/4.5ULD, while can't go far for landscapes , I took this at WO on Sigma SD1 Merrill:

Contas,
feeling pretty squeezed in here!
Nice capture of different worlds,
which is so much a part of many places,
except the dying places like where I live in the post industrial US midwest.
The clarity of the Mamiya 645 200mm 2.8 is quite amazing.
Stained glass is often difficult to shoot without horrible chromatic dissonance.
Here is a shot that preserves the colors on a Nex 5n
(this time without the speedbooster),

This image is a fraction of life - it's real - that is what I am trying for.
Brilliance of a picture is a moment of real life is reconstructed, not a freezed one, the first gives an emotion and inspiration while the 2nd just plain information.

Yes, the Mamiya A 200/2.8 APO is amazing, and so are many other M645 lenses. For example, I've used the 55/2.8N on Mirex to take excellent photos of church stained glass windows, without horrible chromatic dissonance.
