Godox Wireless 433MHz GN33 Camera Flash Speedlite with Built-in Receiver
Quick take
The Godox TT520II is a manual, shoe-mount speedlite designed for photographers who want reliable 433MHz wireless triggering without paying for higher-end flashes. It includes a built-in receiver and RT transmitter, offers M/S1/S2 modes, and comes with a wide diffuser plus filter accessories for softer, more usable light. The main caveat is that it runs on AA batteries and it is not built for wet-weather use, so it is best viewed as a carry-anywhere studio or on-location budget flash.
Pros and cons
Pros
- Built-in 433MHz receiver for wireless triggering (with an RT transmitter included).
- Manual speedlite with 16 channels and multiple modes (M, S1, S2) for flexible setup.
- Guide number 33 at ISO 100, plus a built-in diffuser and included diffuser/filter accessories.
- Buyer-reported value and straightforward performance for the price.
Cons
- Uses 4xAA batteries (no Li-ion pack), so performance depends on your battery choice and swapping habits.
- Not weather resistant, so you will need extra protection outdoors in rain or heavy moisture.
- Not compatible with cameras that do not have the correct single-contact hot shoe.
What buyers think
Buyer-review evidence is consistently focused on value, usability, and day-to-day flash behavior. Reviews commonly describe the TT520II as producing strong light for its price, with wireless triggering and slave behavior working as intended. Multiple comments highlight that it is a good budget add-on for owners who already use Nikon-brand speedlights or who want a multi-camera option. At the same time, the review pattern does not suggest a highly feature-rich “prosumer” flash experience, so buyers who expect advanced TTL features, tight integration, or weather sealing should look elsewhere.
What this flash is for
This is a practical shoe-mount flash for photographers who want manual control and wireless triggering at a lower cost. The built-in 433MHz receiver makes it convenient to add off-camera lighting without needing to mount a separate receiver module. With 16 channels and modes like S1 and S2, it can also act in different triggering scenarios, such as optical or transmitter-based setups (depending on your specific arrangement).
Key features that matter in real use
Wireless triggering at 433MHz, with receiver built in
The TT520II operates on 433MHz wireless and uses 16 channels to help you separate setups. The included RT transmitter plus the built-in receiver is aimed at quick multi-light workflows, such as triggering one flash while staying off-camera.
Manual flash control, plus multiple modes
It is set up for manual exposure decisions, with shooting modes labeled M, S1, and S2. In practice, this suits portrait lighting, simple studio-style lighting, and experimentation where you want consistent control over output.
Output, recycle behavior, and battery reality
The flash is rated with a guide number of 33 (ISO 100). It runs on 4xAA batteries, which is convenient because AA cells are widely available, but it also means your recycle time and overall run time depend on the batteries you use. For longer sessions, having spare AAs or a reliable rechargeable AA setup is a smart part of owning this flash.
Light-shaping help: diffuser and reflection-focused accents
The TT520II includes a built-in wide panel diffuser, along with a diffuser and filter accessories. That matters if you want softer highlights or more flattering catchlights without building a larger modifier setup right away. It also includes a reflection board designed to create a highlighted point in the eyes.
Compatibility and setup notes
Hot shoe compatibility is required
This flash is intended for DSLR cameras with a standard hot shoe. It is compatible with many Canon, Nikon, Sony, Olympus, Pentax, and Fuji models, but it will not work correctly on cameras that lack the proper single-contact hot shoe type. If your camera model is outside that category, verify hot shoe compatibility before buying.
Getting it ready to shoot
When powered on, allow time for recycling to complete before firing. If the indicator does not return to the ready state, swapping batteries for fresh or fully charged cells is typically the next step.
Pros and cons versus what you might want instead
Who should buy the TT520II
- You want a budget shoe-mount flash with wireless triggering built in (433MHz receiver).
- You are comfortable shooting manual lighting and want modes like M, S1, and S2 for different trigger behaviors.
- You need AA-powered convenience for travel or field use, and you plan to carry spares or use rechargeable AAs.
- You want basic modifiers (diffuser and filter accessories) included to soften the light.
Who should skip it
- You require TTL automation or a more advanced, menu-driven flash feature set.
- You plan to shoot in rain or high moisture without extra protection (the flash is not water resistant).
- Your camera does not have the compatible hot shoe type.
Verdict
The Godox TT520II is a strong-value choice for photographers who need a manual, AA-powered shoe-mount speedlite with convenient 433MHz wireless triggering. If your priority is getting multiple flashes working off-camera without paying for high-end gear, this model’s included RT transmitter, built-in receiver, and light-shaping accessories make it a practical pick. Just be sure you are buying for the right camera hot shoe type, and plan around AA power if you will be shooting for long stretches.

Ricoh’s GF-2 is a pocketable, shoe-mounted flash designed to pair with the Ricoh GR III/GR IIIx and GR IV line.

It supports TTL and manual control, high-speed sync, and quick multi-light setups across the Godox 2.4GHz X ecosystem, with a rotating head, touchscreen control, and a magnetic connection for fast switching. The main tradeoff is that, as a small shoe-mount flash, output is best suited to close to mid-range and bounce style lighting rather than demanding long-distance work.
