  <title>Sigma 17-70 Lens Profile for Lightroom 3</title>
  <link rel="self" href="http://blog.erichmusick.com/article/718.html#comment40" />
  <content type="html">&lt;p&gt;I went out shooting this afternoon with my Sigma 17-70 f/2.8-4 OS to test it out after getting the AF adjusted to correct a severe rear focus issue I was encountering. It turned out I'd accidentally reset my D90 from RAW to JPEG and when I went to edit the images in Lightroom 3, I discovered that it couldn't find a matching lens profile. A quick Google search led me to learn that the list of available lens profiles differs when editing a JPEG vs one of the RAW formats. I went back and checked some images I'd taken earlier and sure enough, the profile appeared.&lt;/p&gt;
&lt;p&gt;So, for anyone else who is wondering ... &lt;strong&gt;Several of Sigma's lenses can be corrected in Lightroom only when you shoot in RAW.&lt;/strong&gt; Apparently on a Windows 7 PC you can find the list of lenses supported in RAW at the following location:&lt;/p&gt;

&lt;p&gt;C:\ProgramData\Adobe\CameraRaw\LensProfiles\1.0\Sigma\Nikon&lt;br /&gt;

&lt;small&gt;&lt;em&gt;(replace &lt;strong&gt;Nikon&lt;/strong&gt; with your camera body manufacturer)&lt;/em&gt;&lt;/small&gt;&lt;/p&gt;
