Review on Tiffen 77mm Neutral Density 0.9 Filter: Enhance Photography with Superior Light Control by Bam Reeder

For those who, after hours of searching, are wondering if a 0.9 ND filter will fit a 1.2 lens, the answer is yes. 3 f-stops is enough (so from f-1.2 to 2.8, the point where 1.2 is really useful in broad daylight). Happy 1.2 just can't be used for its intended purpose, frankly what his purpose in life is and why people buy such things. I found out about this when my new 1.2 arrived and I was excited to go outside to check it out. I had to order and wait a few days. It's just great and opens up some new image possibilities for me. It arrived clean and appeared to be well made. The hood is screwed directly into it. By the way, the Voightlander 40mm 1.2 uses a 58mm filter.
