Mamiya ZD sample

Go to last post
Mamiya USA will be introducing the 22MP DSLR at Photokina. Keep in mind that Mamiya USA is not related to Mamiya Japan. They are just a sales company that has the rights to import and sell Mamiya equipment in the USA. Once it is 'officially' imported in the US by Mamiya USA I think you will probably see some reviews in US magazines.

I've been sitting in front of this computer all day and now I'm noticing this thread!?!

I've just downloaded the image and have uttered the 'f' word quite a few times. That's very impressive. I now need to put the kettle on on contemplate my strategy for the bank raid (you can represent me if I get caught).
Thank you very much Quentin. I look forward to more samples :-)

Cheers

Greetings,

Congrats on your new camera I hope you'll have many prosperous and rewarding returns from your new camera. But I do have a question I notice an offensive black blotches and noise in shadow areas like under the bridge and lower right corner of the post and railing and also lack of detail on the buildings (bricks or marble can't tell) and roofs. it could be my monitor, raw conversion software, lense or my unresonable expectation of MF cameras. Please let us know after taking few hundred pictures how well it is doing?

Best regards,
Garen

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 Quentin,
Thanks for showing us a bit of your new toy!

I may be barking here, but isn't there some strange artifacting similar to moiree going on in the windows of this building which I have cropped from the original?

The ZD supposedly has available an AA filter that one can install... perhaps the OP does not have it? Overall the image looks like it would have benefited from a really good low pass filter.

Nevertheless, neat to see someone posting images from the ZD... didn't know anyone on dpreview was posting images made by one.

I was hoping to have seen the original image without any PP, but he had already replaced it by the time I read this thread.

To my eyes, and with the proviso of not having seen the original unprocessed image, it has the same feel about it as do the Kodak images, except LARGER! lol There's something about the clouds and skies that always gets my attention with the Kodaks and this was the same for me. Quite subjective, I know. But there it is. :-)

Its a bit like the Kodak, but larger, but I'd say thr pixel level quality is superior. Similarity in looks is probably just my processing being Kodak-biased :-)

There is some low level moire. An AA filter is an (expensive) option, but I'd never use one. I prefer the sharpness without one, and deal wioth the consequences. Afer all the ZD is just a camera, albeit a very good one, I think

Thanks Quentin. Did you use Silkypix or another RAW converter on this, btw? It would be interesting to see if there is any difference between them in respect of the moiree.

Hi All,

Looking at pics of the Mamiya, I'm curious as to how much surface area of glass you have on the lenses compared to a comparable one your SLRs. They don't look that much bigger. Hmmm.... what happened in Optics 101 ..... I don't think I missed it .... must have been reading a mag at the time ....

I ask, because while technology is bound to march on and in the future sensors will get more densely populated so resolutions will go up, but there is always the ceiling governed by the imperfections in the lens manufacture. The bigger the sensor and bigger the glass area, I'd have thought the more scope you have.

I've heard figures bandied about for 35mm cameras as around 20MP being a typical upper limit for quality lenses.
Anybody got any comments or figures for these larger formats?

Or do you think more R&D is going to be pumped into lens manufacture? Maybe they've started to do this anyway. Again I've read that the Olympus lenses apparently have nearly twice the resolving power in line pairs per mm of 'other' lenses - but of course they need it because the fourthirds sensor is smaller to begin with. (Bring on the Canik fanboys ;-)

Something for me to think more about as I mount my trusty lawnmower and tackle the grass before those clouds I see in the distance descend!

My unscientific observation would be that with the 14n SLR/n type imager @13.9 MPyou're already seeing flaws in lesser lenses, and taxing the best ones. I think that lens resolving power begins to curve off as you increase imager size, so if you doubled the pixel count to 26.8 MP you would not see a doubling of image resolution. Maybe only a 20 percent increase. It sounds like a great answer, doesn't it? So I agree that around 18-20 MP on a 35mm lens would be the practical limit.

Hi Quentin

That looks great - good colour, no funny cloud edges (nice blob on sensor to keep reality in mind), great detail.

and all handheld!

looks like a winner to me.

kind regards

Hi Flick,

Terrible confession to make. I was in Oxford on Tuesday on a case at the county court. Afterwards I pottered about a bit with the ZD, but I did not have a lot of time otherwise I'd have dropped by (if you were there).

The ZD already has a nuce scratch on the toplate and I have cleaned the sensor once already. Its a big Kodak really :-)

That is awesome. I'm very impressed with the quality.

Spectacular splodge on your sensor already, top left BTW...
