LensAlign Pro Plus Focus Calibration System with Long Ruler Kit

The LensAlign Pro Plus Focus Calibration System with Long Ruler Kit is a unique and accurate way to check the focusing performance of your camera and lens combinations. This system provides you with a reliable and easy way to make sure your expensive photographic equipment performs at optimum level. After all, you want your images spot-on sharp since anyone in the business knows that clients don't like excuses - and when you only get one chance to get that money shot, your gear must be in peak condition.

However, no matter what camera/lens you buy, it's probably been mass produced. Even though manufacturers allow for production tolerances, mistakes happen and it is rare that perfection is achieved. If, by chance, your camera is "off" by a fraction and you couple that with a lens that is also off just "so-much", the combination produces an image that will be soft.
