Summary: I was a little skeptical when I ordered this; had a special project to film, a Baptist Heritage Seminar - 6 2 hour sessions. I had to be able to get the entire platform into view, singers on the left, speaker in the middle and powerpoint showing overhead. I was amazed how quality this lens was/is, I was able to double my field of view, then narrow it down to the exact dimensions I needed for perfect framing of the event. DVD's going out today and they look very good.
Excerpt: I bought this converter lens to get better indoor shots at family events with the Grandkids. I got my first chance to use it this weekend. The shots were very smooth and the lens worked just as I had expected. I got great performance throughout the entire zoom range and even in relatively low light the performance was very good. I would recommend this as a great add on.
Excerpt: Useful option to provide extra wide coverage. The only reason for 4 stars is that I would prefer an integrated lens cover and a way to attach Matt Box style filters (such as threads). Glass is nice and product is as described, functions well with the XF100. Cost is a bit high, but the quality of the glass is good.
Summary: I bought this conversion lens to go with a Vixia HF G20, which was an upgrade from an old HF10 and a .66x Raynox "HD" conversion lens. The Raynox was good if you stayed wide, but if you tried to zoom in while using it, the image quality degraded terribly. So I tended to only use it when I absolutely needed to, which unfortunately was a lot. The G20's lens is a bit wider than the HF10's, so I considered not buying a wide angle converter.
