The long-awaited 6x wide-angle high-def lens arrived for my XL-H1. The new Canon HD Video Lens 6x XL 3.4-20.4mm L has a 35mm equivalent perspective of 24.5 to 147mm, making it ideal for indoor videography, especially in cramped Japanese houses! There's a manual iris control ring, although the focus and zoom are still servo controlled.
First impressions: HOLY SMOKE THIS IS A BIG SUCKER. It's considerably larger and heavier than the standard 20x lens. The lens hood itself is humongous, almost a matte box in itself. It also makes the XL-H1 even more front-heavy than it currently is, so you'll need some sort of brace unless you have forearms of steel. Also, I didn't notice until it arrived but the 6x zoom does not have Image Stabilization in it. You don't really need it for wide angle work, but it would've been nice on the longer end.
The XL-H1 needs to be flashed up to version 188.8.131.52 in order to support the new iris ring (I was very confused at first since I ignored the enclosed SD card in my haste to play with the lens). The flash card is provided and after you've flashed it, you have a nice 16mb card to store your presets. I haven't learned if there are any other new features in the 184.108.40.206 software except the iris support.
The price for the 6x wide is set at MSRP $3000 and most retailers have it at $2700, but I bought it through the Canon educational program at about $2300.
Once I have some test footage shot, I'll post them.
