Hi

These downloads are good for 7 days. These are for evaluation only. I will try to do more.
I feel that at iso 50 the ZD has a slight edge. Since I own both cameras the Canon viewfinder smokes the ZD camera. But at the same time the bottom LCD screen on the ZD is larger & better than the Canon. Please note my ZD sensor is a little dirty at the moment. Please have fun on how you process these files. I feel Canon has done a great job. The ZD camera is from March 1996 with no firm ware
up grades. Canon file #13 ( iso 100 ) ZD files # 5891 ( iso 50 ) & #5892 ( 100 ). The Mamiya was shot at 1/250 120 macro ( 50 ) & the Canon at ( 100 ) with the 70-200 f4 IS @ 1/320 all hand held.
You may ask why but I shoot hand held almost all the time. The iso default for these cameras are 50 ZD & 100 Canon. The Canon was at neutral in Picture Style & the ZD has no sharpening in camera.

Thanks Denis

Thank you very much Dennis. As I am interested in both cameras, I have downloaded both, indeed I think the highlights are smoother in the ZD file, less burned out, DR a bit larger, and the shadows (tree silhouettes on the left) are mushier with the canon also. But detail is close enough to give up the ZD advantage for the much better convenience of the Canon (high ISO, speed, lens system etc.).

A used ZD SLR is now slightly below a new 1ds3 price, but with the ZD you are normally bound to ISO50-100 and mostly need a tripod.

BTW, you must have a *very* early ZD from March 1996 - Wow! :-)

Hi
You do not need a tripod with the ZD for most applications. The test with the ZD had a lower shutter speed than the Canon in this test. I think Canon has done a remarkable job with this camera.

Thanx for your effort!

After equalizing the crop in iso100 files, there is nothing blown in either file (I processed both in ACR). DR seems quite similar. Tough competition...

hi Rainer,

Prices of the Sinarback 54 M/MC (22 MPx single shot) have already been reduced by more than 40% and since August. The SB 54 H (multishot)price  has been reduced by 20% starting January '08.

best regards,
Thierry

I would say the Canon looks much better. Your Canon already has a lot of Dust Blobs everywhere. Did it arrive like that?

I have done a comparision today with the Leaf Aptus vs de 1DsIII.
Only one setup (had to rush it).
I hope to take some more time in the nearby future.

I will open a new topic tonight for that.

Hi Denis,
Somebody on this forum once said that they like to shoot clouds. Can you put up something other than clouds? Thanks!

Hi
Make sure you are looking at the right file & yes there is some dust on the Canon & it brand new with less than 20 shots.

Hi
I have been looking at both files ZD (50) & Canon (100) as these are the default for these cameras. I was looking where the crane is on the left hand corner @ 200% on a side by side comparison in LR. The ZD file is a little sharper & smoother. I feel the Canon is not as smooth in the sky area here. I will have to take more shots. But now I will be using both cameras at the same time now. If there is a ZDII in the future it will have to be with the 33 mp chip or the kodax 39 mp chip. The big difference when you pick up these two cameras is the view finder, the Canon 1Ds3 is incredible!!!!!
Thanks Denis

How deos the noise grain compare? not at high ISO 'obviously Canon wins'.

The most important difference to me is that in Canon's file sky is overblown in the location of the sun. ZD is capable to cover a much larger dynamic range. (I used latest SilkyPix to process the raw files)

The Canon shot is swivelled more into the sun and is therefore trying to accommodate a greater dynamic range. The field-of-view is matched horizontally, between the two cameras, except it's a slightly different field   .

Hi
You are correct the Canon is more to the sun.

You've also put the Canon at a slight disadvantage in respect of lens resolution by using f14. The 1Ds3 needs all the resolution it can get because of its great pixel density. It has the pixel density of a 20D or 30D. I think most people who use these cameras would agree that any lens at f14 will produce a slight softening. However, with the lower pixel density of my full frame 5D, I probably wouldn't notice it in a shot like this. The ZD has about the same pixel density as a 5D, slightly less maybe.

For this type of shooting the 1Ds2 always did well.  It has a bias towards the reds, so sunsets look punchy.  The 1Ds2 if exposed for highlights had a nice roll-off, and as for dark areas, who cares, they're just going to black anyway.  The 1Ds2 did well in this regard, and I expect no less from a 1Ds3.  These are the 1Ds2 -









For images such as those above, the 5D had problems because it would clip the sun in a very harsh way.  One of the channels would blow about 1/2 to 1 stop earlier than the others there would be greenish or some other colored halo around the sun.  The 1Ds2 does it too, but to a much, much lesser degree.  IMO scene like this will stress test the sensors much more so -





There are parts of the snow bank that are just blown.  In a small web size it's not a big deal, in print (24'x30") the loss of texture makes the image look a bit too polished (IMO).  It's just a mass of white.  Both pictures are the same scene; one @ ~24mm and the other @ 200mm.  Trying coax much more out of those image isn't possible; and I don't like the HDR comic book look.  Normally I'd shoot a scene like that with a graduated filter, but with 200/1.8 it wasn't possible.  I did used a CPL to hedge the exposure.

Whether the 1Ds3 can match the detail in a 22 MP back (or come close enough) doesn't matter to me.  It's about the dynamic range, how clean the ISO 50 and ISO 100 shadows are, and color fidelity (gradient quality & smoothness).

Enlightening comments John.

By the way, where was that shot of the lake framed by the mountains (with green trees) taken?

The sunset pix were in Hawaii this past September.  The mountain pix with in Banff, Lake Loraine I think.  If you like landscapes, GO TO BANFF!!!!  Awesome location to shoot because there are views everywhere and not much hiking needed.
