Lens

Since neither the focal length nor the effective aperture has changed, the F-number remains the same,

F1.8. Thus, there is no optical sensitivity “loss” involved when using a 2/3” native lens with the LO-32BMT

on a 1/2” camera. As a comparison, if instead of using the 2/3”KJ20x8.5B lens and LO-32BMT adapter,

you were to substitute a 1/2” KH20x6.4 HDTV lens, the adapter would no long be necessary. By applying

the same formula, F-Number = f/D, to the 1/2” KH20x6.4 lens, the lens will have a faster F-Number, F1.4,

compared to the 2/3” lens and LO-32BMT combination.

Focal Length

When using a 2/3” lens with a LO-32BMT adapter mounted to a 1/2” camera, the actual focal length

of the lens does not change. However, the angle of view associated with that focal length changes.

In this case, the lens will visually be more telephoto, by a factor of 1.38x. As an example, the 2/3”

KJ20x8.5B HDTV lens (58.90angle of view at 8.5mm when mounted on a 2/3” camera) will visually

appear to have a 44.60angle of view, that equates to an equivalent focal length of 11.7mm

(8.5mm x 1.38 = 11.7mm)

The actual F-Number of a lens does not change when mounted on a different format size camera.

Using the 2/3” KJ20x8.5B HDTV lens as an example, its maximum aperture is F1.8. When that lens is

mounted on the 1/2” camera with the LO-32BMT adapter, the focal length and effective aperture of

the lens do not change.

The Canon LO-32BMT adapter allows you to mount a 2/3” B4bayonet lens onto

any Sony 1/2” proprietary mount camera such as the new XDCAM HD series,

PDW-F330/F350 while not affecting the optical quality of the lens. It is important to consider

the following information when using a 2/3” lens with a LO-32BMT adapter mounted to a 1/2” camera.

The formula for deriving the F-Number of any lens is as follows:

F-Number = f / D f = Focal Length D = Effective Aperture

1. The images produced will appear visually more telephoto by a factor of 1.38x.

2. The actual F-Number of a lens does not change when mounted on a different format size camera.

If the lens is F1.9 in the 2/3” format, the lens is also F1.9 in the 1/2” format.

3. The Focal Length and F-Stop markings on the 2/3” lens are correct in either format.

4. It is highly recommended that HDTV lenses always be employed on HDTV cameras.

Whether you own or plan to buy the Sony PDW-F350 or the PDW-F330

XDCAM HD Camcorder, you’ll want to make sure there’s a new Canon

HDgc lens out in front. HDgc lenses combine the best features of Canon’s

remarkable lens technologies to deliver HD optical quality and other

higher-end advancements. The HDgc line’s lenses for 1/2-inch CCD

cameras include: the KH21ex5.7 IRSE (telephoto lens), the

KH10ex3.6 IRSE (wide-angle lens), and the KH16ex5.7 IRSE

(standard lens). Canon’s exclusive Digital “eDrive” is

included in all three of these lenses, and is

a principal difference (along with zoom

speed range and a built-in 2X extender)

between these models and the more

economical 1/2-inch KH20x6.4 KRS

and KH19x6.7 KAS lenses.

Canon’s exclusive Shuttle Shot function (available on the

KH20x6.4 KRS), an advanced servo system that facilitates zooming

back and forth between any two focal length positions

and brings an entirely new range of value-

added creativity to hand-held acquisition

systems. The KH19x6.7 KAS lens

is compatible with Sony’s

Auto-Focus system.

A new ergonomic drive unit

a new, smaller drive unit that not only

comfortably fits into the palm of the

user’s hand, but also improves the

feeling of unity between the drive unit

and your hand. These drive units,

featuring a grip

support and

ribbed surface,

are tilted at an

ideal angle in

order to

achieve a

better balance

and to provide

more comfort

and reduce

operator fatigue.

Canon’s innovative technology

user benefits.

Well-Controlled MTF

plus excellent contrast performance

Compact design lightweight in direct response to the equally

compact new tapeless HD camcorders.

Minimizing environmental impact Canon is manufacturing all of its

lenses, including the new HDgc models, without lead, cadmium, mercury,

and other toxins as part of the company's policy to minimize the impact

on the environment.

Canon’s New HDgc Lenses Let You Maximize The Potential Of Your Sony XDCAM HD

Canon’s exclusive eDrive provides nine user-definable function

profiles; a choice of manual, digitally assisted, or fully programmed

control; and instant “Shuttle Shot” to zoom to the longest focal length

for quick check of focus and back focus. Digitally assisted shooting

techniques offered by Canon’s eDrive include graceful “padded” zoom

start/stops so that zooms begin and end softly and without jerkiness.

Canon’s eDrive provides for memorized focus and zoom positions,

repeatable focus with no mechanical play or gear backlash, steady and

slow zoom creeps, and one-button on/off.
