any use the adapter with real HD lenses?
I heard this multiplies the image...
any feedback would be great.
I'm a big fan of the hvx....but also curious about the HD100.
 
Is there a 2/3 adapter too? I've only heard of the 1/2".

Using such an adapter will result is a narrower field of view than if it was used on a native 2/3 or 1/2 camera.

I'd also be interested to hear anyone's findings.
 
so what...the thought of a nice 15,000.00 canon sitting in front with shallow DOF appeals to me. more than a G35 etc

I agree, it would be nice to hire a decent lens when needed, I just think it is a shame that the adapter is so overpriced. I can't see how the price could possibly be justified.

I feel ya baby!
Still, at least we have the option.
 
A multiplier is a device that, when installed between the lens and the camera, multiplies the focal length of a lens. Think Canon's multiplier for its 16X that made any image viewed thorough the lens 1.7X closer.

The lens is not going to give you a DOF change. It will have a different FOV because of the chip difference but it's the "capture plane" that effects the DOF. Thus why a full size 35mm digital sensor gives you the same exact DOF as a 35mm film plane.

Obviously if you put a Lens on with a larger zoom range you could increase a lack of DOF by using the long lens from further away. Sticking 1/2 or 2/3 lens on the HD100 will only change your Crop Factor (visible image).

Not necessarily. I have a fujinon (10-140mm f1.7) lens from an old sony 8mm camcorder that has awesome shallow DOF from 4 feet away.

That's true, but I think comet48 was referring to the multiplication factor (aka cropping factor) of the Field of View going from 2/3" to 1/3", which is around 1.82x

Therefore, let's say you were using a 10mm lens on a 2/3" camera and you wanted to achieve the same FOV on a 1/3" camera, you would need to use a focal length of 5.5mm. 5.5 x 1.82 = 10mm

The widest 2/3" HD lens I know of is the Fujinon 13x4.5, which rents for $250/day.

At this point, the widest option is still the 1/3" 13x3.5 made for the HD100.

Exactly. DOF characteristics will not change no matter what lens you put on the HD100. The only way to get the short DOF of 35mm is to use a mini35 style device in order to "re-photograph" a projected image on a larger ground glass.

Focal length is focal length.

Well unless you use a faster lens. Okay, I'm being a bit anal.:Drogar-BigGrin(DBG)
