1. Re: Lens profile for the new Sigma 17-70 contemporary
ThierryT Nov 23, 2014 3:08 AM (in response to motomanDK)Dear all,
I have the same problem as Henrik. I have the latest mac os (10.10) and Lightroom (5.7) but Lightroom does not recognize the Sigma 17-70 C ("unknown lens" in metadata) and so all pictures taken with this lens are difficult to classify. Initially I thought the problem was from Sigma but when I open the image raw file (DNG) with Aperture or Preview, exif data contain the right lens name. Somebody knows how to fix this issue?
Thank you

ThierryT Nov 23, 2014 10:07 AM (in response to 99jon)Yes I guess it is. I bought it new last September and I have the Pentax mount. The strange point is that in the Lens corrections menu I can select the SIGMA 17-70mm F2.8-4 DC MACRO OS HSM C013 to optimize the image but in the metadata menu the lens is not recognized (even if the lens name is contained in exif data because Aperture reads it properly).
