I am a longtime user of Capture One, mainly with files from a Leaf digital back.
Now I used C1 7.1.6 for the first time with RAWs from my Olympus OM-D E-M5 with the M.Zuiko 2.0/12mm lens (I used ACR up to now with that camera).
After importing the files from the SD card I noticed something strange (which had never happened to me with the Leaf RAWs): all RAWs shot with this body/lens combination are pre-cropped, about 7% of the picture width and height. This is true with or without the "Hide Distorted Areas" feature checked in the "Lens Corretion" tool
Please also note that in the "Crop" tool below, the pre-cropped image show a resolution of 4608x3456px, which should be the "native" resolution of the E-M5 sensor. When I manually correct this automatic crop, the resolution goes up to 4918x3582px, which is kind of unlikely with a 16MP sensor ;-). I know, I know, the RAW image is upscaled anyway after de-bayering, but still this seems strange.
(see three screenshots below)
Correcting this is not trivial for the following reasons:
- clicking the "Reset Crop adjustments ..." icon in the "Crop" tool defaults to the "wrong" crop and not to a fully uncropped image, as it should be.
- un-cropping one image maually and then copy/pasting that to all the other images is hard, because I can not find a way to filter out and select only the images shot with that lens, PLUS with the same orientation (landscape or portrait).
RAWs shot with the E-M5 and the M.Zuiko 1.8/45mm (a lens without much native distortion) or with the Panasonic 1.4/25mm (which has lots of native distortion but alas no C! profile yet) do not show this auto-cropping behaviour.
I also dropboxed the RAW file as a .zip, if anybody wants to play around with that:https://dl.dropboxusercontent.com/u/3949609/_C143865.ORF.zip
Have any of you noticed this C1 behaviour with this specific lens/body combination, or with other lenses and bodies?
BTW, ACR also "auto-crops" a little bit, but only 1 or 2 %, which is negligible for me.
thanks for your input,
