Pros & Cons
👍 Pros
- Full E-TTL II passthrough means your camera's metering controls flash output automatically — a genuine time-saver in fast-paced event or wedding work.
- High Speed Sync up to 1/8000s opens up wide-aperture shooting in direct sunlight, giving you shallow depth of field without ND filters.
- Four independent channels and four groups let you separate multiple lights into distinct zones, useful for multi-light portrait or product setups.
- EV adjustment of ±3 stops in 1/3-stop steps from the LCD gives fine-tuned control without walking to each flash.
- 150-meter-plus wireless range means you can push lights into the background of a large venue or outdoor location without losing signal.
👎 Cons
- Designed specifically for the Phottix Strato II system — it won't function as a standalone receiver with other brands' transmitters or mix-and-match with Pocket Wizard or Godox triggers.
- No built-in transmitter function, so it only receives; you must own a Strato II transmitter separately to use this unit at all.
- HSS range is reduced compared to standard sync mode, which can matter on large location shoots where you've pushed the light far from the subject.
- The LCD backlight, while helpful for low-light event work, draws battery power — long shooting days may require carrying spare batteries.
Frequently Asked Questions
Is this receiver compatible with all Canon speedlites, or only specific models?
It works with Canon TTL speedlites that support E-TTL II — so flashes like the 600EX-RT, 580EX II, and 430EX III-RT are all covered. The Strato system passes full TTL communication, so your camera's metering drives the flash output just as if it were on-camera.
Can I adjust flash exposure compensation directly from this receiver, or do I have to walk to each flash?
The receiver itself carries the EV adjustment from the transmitter side — you push +/- 3 stops in 1/3-stop increments via the backlit LCD without touching the speedlite. That's the real workflow win for run-and-gun event shooting.
Does this receiver support High Speed Sync, and what does that mean for shooting outdoors in bright light?
Yes — HSS fires up to 1/8000s, which lets you shoot wide open in full sun without a neutral density filter. For a Canon 85mm f/1.2 at midday, that means you can still separate your subject from a blown-out background without stopping down.
Do I need to buy this separately if I already own the Phottix Strato II Multi 5-in-1 kit?
The kit ships with a transmitter and one receiver. This PH89016 is an additional receiver — useful when you're running two or three off-camera lights and need each one on its own Strato channel independently.
What is Second Curtain Sync used for in practice?
Second Curtain Sync fires the flash at the end of a long exposure, freezing your subject's final position while motion blur trails behind it — a technique commonly used for moving subjects at concerts or street scenes. This receiver supports it natively via the Strato II transmitter.
