Well, let me first repeat what I am trying to say since quite a long time on this forum. I will try to make it a bit clearer.
Try the eMotion at ISO 100 and try another back from another brand at ISO 100. Compare the images and the histogram. Most probably you will see that the eMotion is 1 stop brighter than the other back, or that you have to switch the other back to ISO 200 to get the same exposure/density. Or in other words, "our" ISO 100 is equivalent to ISO 200 from another back. This is my tests having shown this and this has been confirmed by Steve Hendrix from PPR Digital in his post yesterday. Thus, if you want to compare the noise level, then compare it at ISO100 vs ISO 200. I think I cannot make it clearer.
As for dealers claiming that "Sinar is good in studio, but over ISO 100 one should forget it": some of these dealers should be updated, I confess this. Or then at least tell people that ISO 100 with Sinarbacks is equivalent to ISO 200 with others. This puts things in another perspective, isn't it?
About noise in general: we have always had the same philosophy, which is to not twick or change the raw data too much, and provide the photographer with as much original captured information as possible. So it is with "noise": we do not filter it out by some internal filtering, but provide a very powerful noise reduction feature in Captureshop which can be switched on and off on request and which can be adjusted very precisely. I can only recommend to try it out: being able to adjust "chrominance" and "luminance" noise as well as doing other "fine tunings" with this filter, is a very good thing, IMO. Once you have found the "noise reduction" setting for your particular image(s), you can apply it to all selected images and in a batch process, without having to open each file.
One last remark: your note "I also hear for tethered studio shooting the Evolution 75H is quite amazing at 100". I hope you will translate it now with "at 200". I guess then you will understand that the eMotion is even better than what you might think. Or again, compare "our" ISO 100 with ISO 200 with others, then we can speak at the same level.
Thanks anyway for your remarks and information about our dealers: I guess there is some homework to do for us in this area and it will be done.
Not trying to bag on your product, as I just ordered $85k in gear from Jim in the US office and will give it a fair shot when available. I must also add that I have never even held a sinar digital product. But every dealer I have dealt with has told me that the Sinar is great for product or none moving settings, but after 100 ASA it is no good.
When upgrading from my P25 I looked at everythig and asked advice from everyone. I used the Aptus extensively and at the time of the upgrade V11 was not out yet and when I had been using V10 I left Leaf and decided I would not go back. I never used the H3d because I did not want to be locked into a system, although all I use is the H1/H2 set up for Phase. But I am hoping to get a useable solution for the H1 mount to RZ interface plate. I do miss the RZ, but think that the Hy6 may fix this for me.
My dealers were advising Hasselabld when going into my new back and the CF was quite attractive and the files I was sent at 400 looked pretty good. But then there was flexcolor with all its little mystery bugs and hiccups. I don't care what adobe is comig out with, I am not a fan of LR and love C1. Adobe is for PS. So I went to a P45 in the meantime.
But when your dealer network is telling you not to go with a product they carry and telling you to go XX route, it is quite interesting.
I will be tesitng out the Sinar system when it is readily available with the new emotion. I also hear for tethered studio shooting the Evolution 75H is quite amazing at 100. But as photographers that own our equipment we need a system that can go from tethered shooting to location shooting without a problem.
The only solution that I have found that steps up to the plate is the PhaseOne product. At the moment that is! I am not on a Phase band wagon. I just want something that works without a glitch. They have been the only product I have used that have not failed me.
I hope the Sinar product gets out into the market place, as I do for all the brands. It is just good for all of the shooters.
