QTTL Adapters

Quantum’s QTTL system is fully dedicated to popular camera systems, such as Nikon*,

Canon*, Hasselblad*, Mamiya*, Olympus*, Contax*, and more. See the chart

“Dw series Adapter Features” for the features supported for each camera system.

QTTL adapters can offset Qflash output between -3 to +2 stops (in 1/3 steps)

in relation to the f/number setting on the camera. Even if your camera doesn’t

support fill/flash ratio, the QTTL ratio setting tracks the camera aperture as it

changes, providing automatic fill/flash ratio!

Please refer to the Price List or www

.qtm.com for the latest camera compatibility

with “D” series and “QF” Series TTL adapters.

Sensor Limit – Prevents Subject Blowout

We’ve all experienced those ghostly, over-exposed figures in the foreground appearing out of a dark or

distant background. Subject “blow out” is a shortcoming of flash auto exposure when the background is

far away and the subject is close. Auto exposure tries to fill the background and winds up blowing out the

foreground subject.

Qflash T5d and X5d have the solution, called “Sensor Limit.” Setting the Sensor Limit distance to the

approximate subject distance forces Qflash to ignore the distant background, giving accurate subject exposures.

The Sensor Limit feature is not available on any other camera or flash system. A Qflash 5d with QTTL

adapters lets you use Sensor Limit in Program, Auto and Auto-fill modes, while the flash exposure tracks

the camera f/number settings.

Accessories

Convenience Features: The new back slanted design properly balances Qflash

for bracket mounting and it keeps the reflectors back for wide angle lenses.
