I have a new camera Casio ZR700 which output DNG RAW. Casio have now more models, that output DNG RAW).Good, it use no properiety RAW Format and use the standard DNG. But bad, I can not choose a general profil and can not adjust lens distortion, or CA in C1 pro or express. all settings that available are the same as it is a jpg.

But i need correct lens distortion and CA.
I understand that Capture one is a Software for professional camera. Because small Sensor camera output worse image quality with lots of denoise, RAW i think is here more important, to get a acceptable good enough quality. I test the Demo, and i am surprised of the results from capture one, even with no setting change. the default sharpen is also good. lightroom(support ZR700 and have so build in lens distortion) but can not sharpen enough.

I have ask in a german forum before, maybe its possible but i find not out how it work. Here i have post a image create from C1and the RAW DNG for download

Ok, i understand that capture one Team do only support Professional Cameras, many users that have capture one buy. but maybe please add some sliders to capture one express so let correct the lens distortion, and settings to remove the CA.

Then i like to buy. In RAW therapie there is automatik lens distortion add and this does not know the ZR700, it work good. Here it is written how it work. it work with the embedded image.

but with RAW therapie i get not such a good image quality as in C1 from my image.

  I have more to add to this comment on Capture One 7 DNG handling.
  My observation is that if I convert my Nikon D700 NEF into DNG format Adobe products still recognise the camera type and apply camera specific profiles, they also recognise lens data and apply lens correction automatically.
  In contrast opening the same DNG files in Capture One 7 results in the application of a generic DNG profile which does not always produce optimum results. Further no automatic lens distortion correction is applied and it is not even possible to select the appropriate lens manually.
  Are there any plans to improve the DNG handling capability of Capture One in the future?

  David,
  
  As this is a user to user forum there is no certainty that you will get an official response of any sort. In my presonal opinion that is not a problem especially where the question could be categorized as being slightly peripheral to C1's objectives at the moment.
  
  However I think, were I in the positioning of developing some software for use with DNG specificiations, I would be less that forthcoming anyway.
  
  DNG is a standard - of sorts. The is a common problem in software terms.There are many standards, everybody has one.
  
  If, as a developer, you are big enough and have a broad enough market place, you might feel a need to cover every variation of a standard that someone throws at you. Or you might not.
  
  You might have a desire to cover everything and do it well but the there will be practical realities and commercial realities that bring that into question.
  
  If the standard was indeed a standard one might assume that, logically, everyone would be forced to do something to fit in with it. Or perhaps everyone within a common marketplace would be forced to fit in with it. But it it is one of those standards that isn't completely "standardised" then you might think twice or even be prevented, commercially, from doing anything to align with the "standard" on the basis that you simply cannot justify it in a cost and revenue basis.
  
  Lack of Standard standards is why people developing web sites really need to check their work on multiple browsers of multiple ages. The are "standards" for how html (or whatever) pages should be created and how a browser should interpret them. It's just that the standards are not always followed well (or at all) even by the people who set the standards.
  
  If you have a need to deal with "legacy" products the situation gets even more challenging in most cases.
  
  Then add in lens corrections. (No standards for this as far as I am aware. Each camera/lens/FL may need to be considered individually if standout results are to be the objective.
  
  It's not a simple project and neither is it a simple commercial decision.
  
  My understanding, for what it is worth.
