Having a lens and camera recalibrated by its manufacturer for sharpness when autofocusing can be costly and time consuming—so before you ship your gear out, consider using Datacolors’s new SpyderLenCal to measure your lens/camera body’s accuracy and to recalibrate it yourself.
Often times, lenses and cameras need to be tweaked for perfect sharpness, especially when using a third-party or dated piece of glassware. Thankfully many new DSLR’s offer a focus micro-adjustment feature that allows one to correct the sharpness of focus. The SpyderLensCal acts as a reference when using this feature, giving you a reliable re-calibration.
Priced at $59.00, the SpyderLensCal hits stores in late September.
