MaxTech Transceiver manual

NIf your c amera’s maxim um sync sp eed is s lower than the nu mb er listed th en you mu st u se the slower s ync s peed. C amera eq ualization does not give a cam era fas ter sync sp eeds than th e cam era is des igned to h andle.

For all shutters it can be assumed that a camera with faster external flash sync speeds (X s ync) will have faster sh utter travel than c ameras with s lower X s ync s peeds .

Fas ter sh utter travel times incr ease the allowab le variance. T he table above is b ased on the following shutter travel times:

•Focal Plane (35mm) – 1/1000 (0.0010) to open, 1/1000 to close

•Leaf shutter at f: 8.0 – 1/2000 (0.0005) to open, 1/2000 to close

If a f lash is g enerating light w hile the sh utter is m oving th en you will see the s hutter in the exposure for focal plane shutters. You will see a loss in F stop exposure using a leaf shutter if the flash is generating light as the shutter aperture opens or closes.

A variable flas h du ration will also aff ect thes e calc ulations. A slow f lash is visible for longer and more likely to affect exposure while the shutter is in motion. A short flash duration reduc es the likelihood of timin g varianc es affec ting the expos ure.

It is d ifficu lt to measu re a s hutter’s travel tim e or a flas h units duration an d it usu ally requires extremely expensive test equipment. Some electronic flash manufacturers print their flash durations in their manual. The best method for understanding your equipm ent’s eq ualization cap abilities is to s hoot m any test expos ures over a range of settings.
