This V4 version is way improved over the previous V2 and V2s versions in gadget infinity cactus review. One not needs an antenna modification for reliable triggering.
I love that the triggers have a trigger voltage vary of 0-300V. You so don't have to be compelled to listen to the trigger voltage of previous, low cost flashes, not like with another triggers which is able to solely operate within the ranges of either 0-12V or 12-300V. The triggers even work with positive and negative polarity voltages.
I additionally love that the receivers take standard AAA batteries or accumulators. Solely the transmitter needs a rather special battery (L1028 / 23A 12V) however this one is rated to last for a year.
One transmitter will hearth an arbitrary range of receivers and with sixteen channels to selected from you'll be able to simply avoid alternative shooters or interference from alternative radio sources.
Receivers will work as a flash stand during a pinch however even have a tripod screw mount. They'll hearth flashes via hot-shoe or with one among 3 cables (all equipped within the transmitter + receiver package): three.5mm plug, 6.35mm plug, or laptop sync cable.
I like the scale and appearance of the receivers, triggering works at 1/180 with none issues (they may additionally simply handle 1/250 if our Pentax cameras could) and could not be happier aside from the subsequent downsides:
My triggers are typically terribly reliable however with the batteries equipped the vary is 15m most, not the 30m specified. I've tried them outdoors and with freshly charged accumulators however may never reach something near 30m. Maybe i am going to get that vary with a distinct set of batteries however I doubt it as i attempted a replacement battery within the transmitter and freshly charged accumulators within the receivers. N.B., another reviewer got near 100m out of their Cactus V4. I attempted to avoid radio interference with alternative 433MHz devices however haven't any means of knowing how polluted my check areas are.
BTW, the review referenced on top of attests that the triggers deal with a 7FPS shooting frequency. I have not performed such check myself nevertheless.
A slight downside is that the transmitter should not be too near the receivers, otherwise you will get misfires. Normally, this is not a haul why use radio triggers if a cable would do? however once I used the triggers in a terribly macro state of affairs where I even have the camera in one hand and also the flash within the alternative during a very crammed area, I typically got misfires as a result of the transmitter and receiver find yourself being too shut along (they were practically touching every other). I feel constant can happen with alternative triggers furthermore. Radio managementled model cars have constant property; you have to own a minimum distance to them before they're going to react to the the remote control. For the Cactus V4 a few of inches can do.
I take into account it a style flaw that you simply cannot flip the receivers on/off if a flash is mounted on them. All my flashes block the switch after they are mounted. If you forgot to show the receiver on, you can not do it when having mounted the flash. Not an enormous downside however appears somewhat avoidable.
BTW, the service from Gadget Infinity is top-notch! They replied to all or any my queries in no time and were continuously terribly useful. My expertise with them was nothing in need of wonderful.
These are terribly cheap triggers and that i believe you get plenty over you get hold of. alternative systems can offer higher vary, support TTL, and will offer a lot of rock-solid reliability, however they're additionally (an) order(s) of magnitude costlier. For the budget-minded amateur these triggers are seemingly to be over adequate.
BTW, note that Pentax flashes have a really low trigger voltage and whereas they're compatible with the Cactus V4 triggers beneath traditional conditions, they'll begin taking part in up in terribly cold conditions. there's a tweak that solves this incompatibility between the Cactus V4 and Pentax flashes in terribly cold temperatures. EDIT: I perceive that the manufacturer has worked on this issue and current units might not have a haul with the Pentax flashes in terribly cold weather anymore.
Final tip: If you discover your flash fits within the receiver hot-shoe too tightly (I personally do not have that problem) you'll be able to simply take away an additional metal hot-shoe plate that acts sort of a spring within the receiver with a screwdriver.
Have a glance at how the Cactus V4 triggers seem like within the box and with flashes hooked up.
P.S.: The overwhelming majority of flashes is compatible with radio triggers just like the Cactus V4. There are a number of that can't be triggered off-camera with any similar radio trigger as a result of they need dedicated information communication with a the camera. One example for such an exotic flash is that the Pentax dedicated Centon FG105D, aka, Promaster 7000m and Quantaray PZ-1 DSZ (the Nikon dedicated version can work). If you have such a flash and it's an optical slave operate then here's the way to fix the matter with a trifle of DIY.
