Catus Wireless Flash Trigger

A Demo of my catus wireless flash trigger on K100D.

Sometime it missfire -- but for 30-40 bucks, it's the cheapest solution to wireless flash :-) and you can also do multiple flashes setup

Don'T Waste money, CACTUS Wireless Flash Trigger V2s u cant get the SYNC speed needed to do anything creative. Box says 1000/ but canon only 200 fail!

wtf

Ts = shutter speed

Tf = flash speed

Tr = transmission time from V2 transmitter to receiver

Tfv2 = responding time of the flash after V2 is in use

Tfv2 = Tf - Tr, Therefore, Tr = 1/500s Tfv2 = Tf - Tr = 1/500s Therefore Ts = 2 x Tfv2 = 1/125s only.

So don't waste your money, buy the pocket wizard

it's cheap and if u dont need the speed it's fine. spending 150 buck on a a pocket wizard is not practical when u doing cheap photography.

[johnyeros]

I have the k100d also.... how many flashes can you trigger with this and where can I get one?

The battery terminal on the transmitter can make intermittent contact. They have a metal terminal with a small depression that forms a socket which holds the tip of the battery terminal. This socket was formed too deep and the battery terminal could not reach to the bottom of the socket and make contact. It was perhaps a thousandth of an inch gap and the unit misfired most of the time. I decided to take it apart and reshaped the terminal slightly and it worked fine thereafter.

They ship anywhere if you buy that type (PT-01, PT-04, PT-04 Cactus). It ships from Hong Kong.
