I tried adding some sharpening. The software I use evaluates the current sharpness of an image and privides a recomendation for the level of sharening required, the software, focus magic, recommended a setting of 1, the ,owers setting.

Dont confuse low contrast with lack of sharpness. The original image is low contrast

The sharpned sample (with some slight contrast boost) is here

Just a small part of the original.

Hi Quentin,

I'm not an expert, but wow. Sure looks good to me. I'm sure your going to enjoy it. I hope you post many more images taken with it. Thanks for posting.

It's great! A very difficult scene for any digital camera... lots of detail... minimal aliasing & moire...(no.. it's not perfect) gobs of detail... no color shifts that I can detect.

Blows the Kodak away in my opinion... Thank you VERY MUCH for sharing this info & image!

I want one!!

Hi Quentin,

Looks very promising to me, has incredible details. But dust starts to deposit on the sensor already.....:-(

Thanks for taking all the trouble to entertain us as the free-riders.

Best,

Choi

Hi Choi, all

Yes dust is going to be more of an issue I fear. that big sensor seems prone to attract it, and with prime lenses there is more opportunity for dust to enter.

Hardly any CA visible and fewer artifacts than the Kodak. In fact pixel level quality is very good, significantly better than the Kodak, but nothing is perfect. I am inclined to think Silkypix would have done a better job at decoding. I might try that for any future samples.

So far so happy with the major bank balance reduction :-)

Hi Albert,

the Dalsa sensor seems free of colour shifts. In fact at low ISO its free of any obvious nasties that I can detect, pretty much as you said - lower moire, alsiasing etc. U also rate Mamiya lenses highly from when I owned 7II. The 35mm is better built and has more pleasant manual focusing than the 80mm I used for this sample shot.

Q.
 
hi quentin,

looks great. allows the mamiya to make black reference shots? if so you should do before every exposure longer than 1 second with the dalsa sensor. try out how long you can go with base iso. is it iso50?

i think the camera is a great tool as long you dont depend on shift lenses.... and the difference to the slr is just the difference between the higher pixel count and the simple fact thats a dalsa sensor, if you will se a p25 it will look more than the known kodak look ( which has other advantages.... and the p25 can make longer exposures ). what a pity that mamiya wasnt faster with this camera. mamiya workers in munich told me that this was a management decision cause their jpeg in camera proceesing was not working llong time well enough and - although all other wanted to come to the market - the management decided to wait till the jpeg function is better. what a nonsense in my eyes..... who is using jpegs with mf cameras?
 
Hi Rainer,

Yep, base ISO is 50. Not sure about black ref shots, I'll look in to it.

I agree, ridiculous decision by Mamiya to delay. They could have disabled jpegs altogether if it was a concern and added it back in with a firmware upgrade when they were happy. If it had launched on time, it would have been a sensation. Its still a very nice tool with excelent image quality. Somewhat overlooked.

Don't Zork make shift lenses that work on the mamiya mount?

The camera's output looks great. I'm wondering what wide angles are available for this body? If I get one, it would be mostly for architectural photography. Also, why have we seen no reviews for the production model camera on this site?

Hi Q,

Very nice detail! The shadows looks happily noise free.

The orange crane hooks against the black building and the blue bins on the ship look a little lively compared to the rest of the scene. A little velvia like!

Also the prominent crane and some surrounding buildings seems to be leaning.

Sorry if this has already been asked, as I haven't read the other threads, but why the sky NR???

All in all, I'm green with envy!

Kind Regards

Paul

Hi Paul,

I always run NR on the sky, as its the one place you will see any noise showing up, and there was a hint (no more, less that the 14nx at base ISO).

Personally I think I have slightly over-sharpened an image for screen viewing.
