Datacolor has announced the SpyderLensCal focus calibrator. The device allows photographers to measure the AF performance of their camera/lens combinations. On DSLRs with a micro-adjustment feature, this tool can be used to help determine the best values to set in the camera's custom settings menu to correct front or back focus. SpyderLensCal will be available from September 6, 2010 at a suggested retail price of $59.

Tamron has announced that it has cooperated with Adobe in the creation of profiles for the Photoshop CS5 and Lightroom 3's Lens Correction feature. The latest version of the image-editing software will automatically fix distortion, chromatic aberration and vignetting for all currently available Tamron lenses (no word yet on the latest 70-300mm F4-5.6 VC USD though).
