二手 Datacolor SpyderLensCal 最佳化您的 DSLR 自動對焦

My camera's autofocus had been slightly off for months, and this tool made the correction process incredibly straightforward. It's amazing how much sharper my portraits are now after a simple calibration with the included target chart.

The target chart made it painfully obvious one of my lenses was front-focusing by a solid quarter-inch, and the software-driven correction process was straightforward enough that I didn't need to pull out a manual. Now my 50mm is razor sharp at f/1.8, which is exactly what I was hoping for.

I was skeptical about software fixing a hardware issue, but the SpyderLensCal’s guided process made it really simple. My 50mm lens now nails focus every time, even wide open.
