That's great for longer lenses, but sucks for the wide angles ones. I'm looking to buy a lens in the 16mm range. But my digital camera its going to be increased.

I've heard there are some lenses now being built for digital slr's without the conversion ratio. Is there a 16mm'ish lens like that?

When I buy that lens I'd like to get the full 16mm not 24mm.

Thanks!

You can think of the digital camera as being a different format. An 80mm lens is considered a normal focal length on a medium format, as opposed to a 50mm on a 35mm camera. To get the same field of view for a digital SLR, you'll need something even shorter, like around 30mm, assuming around 1.6X factor.
