Lenses for HD ENG

Professional ENG requires interchangeable lenses

The SD 4:3 experience is that the average ENG shoot requires a mild wide angle
lens, however, distant action may require a relatively powerful telephoto lens. The
ProHD standard HD lens (Fujinon Th16x5.5BRM) offers a good compromise
between wide angle and telephoto, and is highly cost effective when packaged with
GY-HD250U camcorder at a US list of $10,995. One of four other optional lenses is
the Fujinon HTs18x4.2BRM fitted with Fujinon’s DigiPower servo system, offering
outstanding HD performance at a US list of $10,800 (lens only).

Fig. 21. This table shows the flexibility of the ProHD camcorder with
two standard Fujinon lenses, particularly Max Relative Aperture, Min
Aperture and the availability of both ½-inch and 2/3-inch lens adaptors.
The standard Fujinon Th16x5.5BRM offers mild wide angle performance
indicated by 5.5mm focal length and about 50 degrees horizontal
angular field of view. The optional HTs18x4.2BRM is 13 degrees wider
at 63 degrees with 18x zoom. JVC also offers a wide angle converter
(WCV82SC about $500) to fit the standard Fujinon lens, increasing
horizontal angular field of view to about 58 degrees.
Besides the two lenses listed in the above table, three additional 1/3-inch lenses are
available: Fujinon Th13x3.5BRM (very wide), Fujinon Th17x5BRM, and Canon
KT20x5BKRS.
