Disclaimer: Before I start this CyberSync mini review, I would like to state that I am not in any way associated with Paul c Buff and his company. I gain no financial benefits from giving this honest review of CyberSync.
There are hundreds of CyberSync reviews on the net, so I will keep this review short and straight to the point. I received my set of trigger and 3 receivers a week after placing an order with the Australian Distributor and have been doing outdoor testing, and of course indoor as well.
What is CyberSync?
CyberSync is a remote control system that enables off-camera flash photography. A photographer can place “lights” away from the camera and remotely fire them, illuminating subjects.
The system consists of transmitter units (CyberSync CST/Commander), and receivers (CyberSync /CSR/CSR+/CSRB/CSRB+).
The test was conducted with 1 Canon 580EX speedlite, and 2 Canon 580EX speedlites. All flashes set to manual power at 1/8 and 105mm zoom setting. The camera used to capture below images was a Canon EOS 300D, in manual mode at 1/250 and f/8.0. Ambient light was deliberately under-exposed to verify that flash was triggered.
5 metre: 100% fire rate
10 metre: 100% fire rate
40 metre: 100% fire rate
110 metre: 100% fire rate
130 metre: 100% fire rate
Camera maximum speed sync test:
Canon EOS 300D at 1/250, f/4.5. No black banding on the bottom of the frame
Same test, 1/320, f/4.5. As you can notice, black band on bottom frame.
- Receiver unit uses standard AA battery. This type of battery is easy to find at local supermarkets/stores.
- Transmitter unit is extremely small and fit snuggly on camera hot shoe.
- 100% reliable up to 130 metres and a whole lot better than eBay triggers.
- Off-camera flash will sync at camera maximum sync speed. For the Canon EOS 5D Mark II, this was tested at 1/200.
- There is no lanyard loop for hanging the receivers. People suggest using Wii remote strap over the battery cover. Personally I am using mobile/cell phone bag, as pictured.
- No OFF button, receiver unit remains ON for 1 hour and will go into standby mode after 1 hour of idleness.
- PC Sync cable may become loose, but this is easily fixed by using rubber band.
- Trigger battery CR2450 can be difficult to track down.
In conclusion the CyberSync is a great upgrade over eBay triggers, for an affordable price.
[Update 21st Dec 2010] The battery (CR2450) on my CyberSync CST transmitter decided to kick the bucket after less than one year use. It was difficult to locate a local store that sells this type of battery. I event went to the city to find it, there was a watch store asking for a whooping $18 but I declined the offer. My search landed me on Dick Smith, thank god, $4.20 per battery!
