About Quantum QF63B

The Tele Reflector QF63 can be used with Qflash models T, X, T2, and X2. It provides a narrow, powerful light pattern and is ideal for use with telephoto lenses.

The QF63 will illuminate about an 18 degree area. The equivalent lens focal lengths are approximately a 135mm lens for 35mm format, and a 250mm lens for 6x6 format. Higher focal lengths can also be used.

The QF63 comes with a flashtube spacer which must be installed to achieve the tele light pattern. The light intensity will increase approximately 2 stops over the standard Qflash reflectors.

In manual mode, close the f/stop on the camera lens by approximately 2 f-numbers higher than shown on the Qflash display for normal (N) reflector position. (Flash meter readings are always recommended for critical exposures).

For automatic operation you must use either a TTL adapter or else the Remote Sensor QF21. This is because the QF63 reflector blocks the sensor on the Qflash.

The QF63 consists of a large parabolic reflector and a flashtube "spacer" QF63S. The spacer properly positions the flashtube to provide the 18 degree telephoto light pattern. If the spacer is not used then the flashtube is in the normal recessed position and the light pattern is similar to a wide angle 70 degree portrait reflector.

If the QF63 is used with the Qflash in the Automatic mode you must also use the remote Sensor QF21 because the Telephoto Reflector will block the Qflash sensor. The QF63 is compatible with all Qflash TTL adapters and does not require the QF21 when in the TTL mode.

Sandy B  Will this QF63 Reflector fit and work on a Quantum Qflash TRIO (QF8)?
ASHER K  I have only used this refector with Lumedyne heads and can assure anyone that these fit perfectly. This obviously doesnt answer the question but should help others who use the Lumedyne system. the reflectors really icrease the throw of the heads and helped illuminate an entire concert hall stage from some 80-100 ft away in the balcony.

A bare-tube flash is just like any other flash--except that it has no reflector behind the flash tube. It sends light relatively evenly in all directions (except directly down). Read More
