ENGLEWOOD, Colorado (February 18, 2003)…PENTAX USA introduces the *ist 35mm Auto Focus camera, one of the world’s smallest in the Auto Focus SLR category.  The PENTAX *ist SLR incorporates a host of advanced, user-friendly features for easy operation and more creative results.  Feature highlights include a multi-mode exposure system with an innovative Auto Picture mode and an accessible illumination mode dial, a 16-segment multi-pattern metering system, an 11-point Auto Focus system, a 1/4000-second high-speed shutter, 17 custom functions, a large LCD panel, a multi-data LCD viewfinder indicator, and a retractable auto pop-up flash.  The *ist 35mm also accepts a full range of legendary, high-quality smc PENTAX interchangeable lenses and accessories — including two newly-introduced zoom lenses.  All these features complemented by a BG-20 battery grip maximize the fun and excitement of advanced SLR photography. 

PENTAX will debut the small, full-featured *ist at the Photo Marketing Association’s (PMA) Show* from March 2-5 in Las Vegas.  PMA hosts the annual trade show where manufacturers in the photography industry showcase their newest products.  

*PMA Booth C140

The new PENTAX *ist offers superior 35mm SLR performance with compact dimensions and easy operation and display systems to satisfy a wide range of photographers from demanding professionals and advanced amateurs to SLR novices.


Major Features of the PENTAX *ist:

Ultra-compact dimensions and functional design
Measuring  just 4.8 x 3.3 x 2.5 inches (122mm wide, 84mm high and 63.5mm deep) and weighing 11.8 oz. (335 grams),  all PENTAX *ist  controls are positioned on the top and back panels for easy operation and accessibility.

High-precision 16-segment multi-pattern metering system with user-selectable spot and center-weighted modes.  A new 16-segment multi-pattern metering system helps solve the most complicated lighting conditions to produce beautifully exposed photographs. In addition to an all-purpose multi-pattern mode, the *ist offers spot and center-weighted modes for specialized applications.

Sophisticated 11-point Auto Focus system with cross-shaped AF point selector and LED viewfinder indicator.  An advanced SAFOX VIII phase-matching Auto Focus system assures that *ist delivers crisp focus on subjects even under poor lighting conditions.  A new11-point AF sensor constantly monitors 11 different points in the image field and covers a wide area — both vertically and horizontally — to ensure optimum focus. In addition to the “AUTO” mode — where the camera automatically selects the optimum focusing point — and “SPOT” mode — where the focus area is narrowed down to a small area at the center of the image field — the *ist offers an innovative “SELECT” mode, where the user can select one of 11 AF sensor points using the cross-shaped AF point selector on the back panel. This select AF sensor point is confirmed by an LED pointer in the viewfinder.  The sophisticated AF system also features the predictive Auto Focus function, which automatically activates when the system detects subject motion and predicts the subject position at the moment of shutter release.  This function even allows the photographer to shoot a few frames after the subject has moved out of the AF sensor field.

Auto Picture mode and illumination mode dial.  When the Auto Picture Mode is selected, the *ist automatically selects the most appropriate auto-exposure mode from five different programs, based on the subject’s distance, lens focal length, lighting conditions and subject motion.  This ensures better results for every subject in every situation and allows the photographer to concentrate fully on shutter opportunity and picture-framing.  The large illumination mode dial clearly indicates the selected exposure program, even in the dark.  The selected program also is indicated in the viewfinder indicator.

Multi-mode exposure system.  In addition to the Auto Picture Mode, the *ist offers six user-selectable Picture Modes, two conventional auto-exposure modes (Aperture-Priority AE and Shutter-Priority AE), Metered Manual mode and bulb mode.

Multi-function retractable auto flash with auto pop-up feature.  Covering an angle of view as wide as 28mm, the auto flash automatically pops up and discharges when the camera detects low-light and/or backlight situations.  It also retracts to the storage position automatically when the power is off.  The red-eye reduction function effectively reduces the annoying red-eye effect in subjects’ eyes.*  Advanced TTL flash control system simplifies complicated flash techniques (such as daylight sync, slow-shutter sync and bulb sync) even when used in combination with accessory flash units.  Especially when combined with the AF360FGZ, *ist offers a variety of advanced wireless remote functions.  In addition, it briefly discharges in the dark to assist the camera’s AF system.
* This mode does not eliminate “red eyes” in all instances.

1/4000-second high-speed shutter with 1/125-second flash synchronization.  The compact, reliable shutter unit offers a top shutter speed of 1/4000 second to freeze the decisive moment of fast-action scenes and features a high flash synchronization speed of 1/125 second, so photographers may open up the aperture to capture dramatic flash images.

User-adjustable custom functions.  The *ist offers 17 custom functions enabling the photographer to customize some basic camera functions to suit individual preferences.  These functions include the AF pointer display in the viewfinder, the LED illuminator operation mode in the LCD panel, the order of exposures in the auto bracketing mode, and the timing of remote shutter release.

Large, easy-to-read LCD data panel with automatic illuminator.  Located on the back panel, the multi-data LCD panel offers a full range of information with large icons and numbers to supplement the camera’s user-friendly operation system.  Users may  activate its orange LED illuminator by turning the main switch to the preview position.  With the custom functions, users may select automatic illumination under low-light conditions or deactivate the illuminator at all times.

Bright viewfinder with full-information LCD viewfinder indicator and AF pointer.  Thanks to the renowned Natural-Bright-Matte focusing screen, the *ist offers a sharp, clear viewfinder image even in unfavorable lighting conditions.  The LCD viewfinder indicator at the bottom provides a full range of information, including the selected Picture Mode and exposure compensation factors.  For easy data confirmation, *ist comes equipped with automatic brightness control to change the brightness level in proportion to the subject’s lighting condition.  Within its image field, the viewfinder features LED AF pointers, one of which lights up to indicate the user-selected AF sensor.  The diopter adjustment mechanism built into the viewfinder eyepiece allows the user to adjust the viewfinder image between –2.0m-1 and +1.0m- 1 to obtain the clearest view of the subject.

2.5-frame-per-second high-speed motor drive.  The high-speed motor drive winds the film at a speed of 2.5 frames per second. The user can select either single-frame advance or consecutive advance with simple pushbutton operation.  It also simplifies film loading and rewinding operations.

Effortless auto bracketing.  With a single shutter release, the photographer can capture three different exposures of the same subject (in order of proper exposure, underexposure and overexposure) in all exposure modes (except Bulb mode).  The desired compensation value (±0.3EV, ±0.5EV or ±1.0EV) can be selected using one of the custom functions.  The use of auto bracketing as well as the selected compensation value are indicated in both the LCD panel and the viewfinder display.

Easy-setting exposure compensation and AE lock.  Using the exposure compensation button and the select dial, the photographer can easily set the desired compensation value within a range of ±3EV in 1/2EV increments (except when the Metered Manual mode is selected).  Positioned at the upper right-hand corner of the back panel, the AE lock button makes the camera memorize the measured exposure value for approximately 20 seconds, during which period the photographer is free to re-compose the image.

Creative multi-exposure.  Photographers can make two exposures on a single frame with pushbutton ease to produce dramatic, eye-catching images.  To expose the same frame more than three times, the photographer simply needs to repeat this operation after each exposure.

Depth-of-field preview.  The depth-of-field preview function is electronically operated for easy confirmation of the in-focus area in the image field before the shot to help ensure photographers create their desired visual effect.

Handy wireless remote control.  In combination with the accompanying remote controller, the *ist offers the convenience of remote shutter release from a distance.  The user can select either an instant release or a three-second-delay release using one of the custom functions.  The operation is confirmed by the self-timer indicator on the camera’s front panel.

Durable metallic lens mount.  The *ist features a durable metallic lens mount to hold the lens firmly in place and minimize wear caused by countless lens changes. 

Data recording capability.  The *ist allows the user to automatically record the date, or day and time, of picture-taking on the photograph for quick, easy reference of captured images.

High-performance smc PENTAX 35mm lens system.  PENTAX offers a selection of PENTAX FA- and F-series Auto Focus lenses for use with the *ist to meet the diverse requirements of its users, from ultra-wide angle to super telephoto, and to special-effect lenses such as fish-eye, macro and soft-focus.  To minimize the overall size of the *ist with a lens attached, PENTAX developed two compact, high-performance zoom lenses as ideal partners for the *ist: the smc Pentax-FA J Zoom 28mm~80mm F3.5~F5.6 AL and the smc Pentax-FA J Zoom 75mm~300mm F4.5~F5.8 AL.  All smc PENTAX lenses are treated with the acclaimed Super-Multi-Coating to reproduce sharp, high-contrast images with minimal aberrations.

A wide range of optional accessories.  Most existing PENTAX 35mm-system accessories can be used with the *ist, including the AF360FGZ dedicated flash unit.  In addition, the new BG-20 battery grip, which is exclusively designed for use with the *ist, is powered by four AA-size batteries, and it features an enlarged grip and a vertical-position shutter release button.
