Fujitsu Operation Timer Economy Light Flashing

but it is unsettling to have the upstream light flashing

It looks exactly the same as the one in my Fujitsu Quaderno.

I use this with my 50D for astrophotography. The interval and timer functions allow for hands free operation of the camera for multiple long exposure shots of star fields using my motorized equatorial mount. It reduced the likelihood of introduced vibration and means I can keep my hands in my pockets while standing on top of a very cold mountain. That standard remote function is also incredibly useful for taking macro shots and limiting camera vibrations on a tripod.

Good to have an economy pack of the most used inks.

Great economy storage

Super light weight and easy operation.

Works well smooth operation and light weight.

This is a very nice headlamp, without two levels of white light, a red light and a flashing red light.  Having the battery pack on the back makes it much easier to balance and the straps are adjustable over a wide range.

Great size, love the built in light (it has flashing mode for some reason, just if you need to give someone a seizure on a film set?) I have always wanted this Porta Brace bag but kept talking myself out of it. I finally pulled the trigger on buying one and I'm glad I did. Sometimes I have a small lens in it if i am shooting an event with a smaller camera, but on a full set I kit it out with all the tools I'll need. for camera department. If you are on the fence about it, do it.

This flashing is amazing. The variable light settings to the strobe. No concerns on purchasing the light at all. I would love to give one to every person in my family. BUY IT YOU'LL LOVE IT!!!!
