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.
