SpyderLensCal

The US/Swiss colour management giant, Datacolor have just started shipping their latest product, the SpyderLensCal. It's an interesting product, not just for what it does, but it shows that Datacolor are looking beyond colour management into other useful goodies for the photographer.

The SpyderLensCal is essentially a precision plastic target and graduated scale that measures the focus performance of your camera/lens combination. If your autofocus is slightly wrong, you can then make adjustments using the autofocus correction facility found on some modern DSLR cameras.
