Specifically, is the lens they are showing the 16x 7.3-117mm or the 13x 3.5-45mm? The pictures show a 7.3-117, however some of the posts mention a 5.5-88mm.

Is the standard lens really too long and not wide enough?

What is the power of the wide angle adapter for the 16x lens?

And last but not least, and important to me because of my mattebox, what is the OD of the len 16x, 13x, and wa adapter? My mattebox is 85mm with reducers to 82mm and 72mm.

Thanks,

David

The 16x: 16x5.5. The 13x: 13x3.5. The standard lens is plenty wide (5.5). The zoom-through wide converter (not adaptor) is .8x. I6x lens is 82mm.

The 16x has basically an identical focal length to the original Canon XL1 16x lens, or the Canon 16x manual lens. If you've got a DVX, the wide end would be about equivalent to a DVX zoomed in to about Z13. The long end of the lens would be way more telephoto than the DVX.

A 13x3.5 would be an incredibly wide stock lens, about equivalent to a DVX with a .8 wide-angle adapter on it. The maximum telephoto on that lens would be about the same as the DVX at Z99.

I guess, in terms of lenses, the HD100 is way ahead of the bunch. Both lenses a very felxible lenses.

Interchangeable lenses does give you a ton of options. There are also a surprising array of options for fixed lens cameras if you shop at Century Optics. In considering the HVX200, I'm glad Panasonic made the lens a 13x, instead of the 10x on the DVX100a. A .7 wide converter and a 1.6x extender will be a must for me on the HVX200. Back to the HD100 though, there is nothing like interchangeable lenses to achieve certain production values from footage. I'll buy both cameras and use them in different ways - just like I've been doing for years with full-sized cameras (HD, Beta, DVCPro) and mid-sized ones (PD170, DVX100).
