The LensAlign MkII has surpassed all of my expectations. I had hesitated to buy the previous model (LensAlign Pro) due to the cost. At less than half the price of the previous model this will do everything I need. Assembly was quick, simple and required no tools. The included instructions were easy to read and understand. After assembly the LensAlign tool seems robust and precise. The tool offers a unique sighting tool that allows the user to, simply, achieve a truly accurate parallel alignment between the camera lens and the LensAlign focusing target, guaranteeing the most accurate results possible. I would definitely recommend this product to anyone who wants to achieve and/or confirm the most accurate focus possible with all of their lens/camera combination.
