MEDALight Upgrade Aluminum F1s Mini Camera Flash for Ricoh GR3/GR3X/Fuji/Sony
Quick take
The MEDALight Upgrade Aluminum F1s is a lightweight hot-shoe mini flash built for compact cameras with a single-contact hot shoe, including Ricoh GR models and popular Fujifilm/Sony bodies (with exclusions). It uses a built-in rechargeable 128mAh lithium battery and is tuned for simple fill-light use, not big-distance lighting. If you need reach or you plan to pair it with larger lenses that can create shadowing, this may feel underpowered.
Pros and cons
Pros
- Very portable build (about 28g) in a compact aluminum body, designed for travel and everyday carry.
- Type-C charging with a built-in rechargeable 128mAh lithium battery, so you are not swapping batteries mid-shoot.
- Simple operation with a single gear setting, aimed at quick beginner-friendly use.
- High-speed sync rated up to 1/500s.
Cons
- Limited output, with a recommended working range up to about 4m, and guide number listed as GN5 (ISO 100).
- Only compatible with cameras that have a single-contact hot shoe, and it is not compatible with certain popular models (including Sony ZV-1F and some Canon Rebels).
- No water resistance rating, so it is better treated as indoor or dry-weather gear.
What buyers think
Buyer-review evidence is mixed but generally points to two themes: the flash is easy to set up and fits well for owners of compatible compact cameras, and the output is modest. Multiple reviews highlight the mini size, solid feel, and straightforward use (including charging via USB-C on compatible setups). At the same time, there is also review feedback indicating the flash can struggle for low-light situations at typical settings, so it can feel more like a fill-light tool than a powerful strobe replacement. Overall, buyer-review evidence is limited in volume, so patterns are suggestive rather than definitive.
Design and portability, built for compact cameras
This flash is designed to stay out of the way. With an aluminum construction and a small footprint, it is meant to complement compact bodies like the Ricoh GR3/GR3X and similarly sized systems. It is a hot-shoe mount unit, intended to sit securely on a single-contact hot shoe and remain stable during shooting.
Power and performance for real-world fill light
The unit uses a built-in xenon flash element and is specified with a color temperature around 6200K (plus or minus 400K). It also lists a guide number of GN5 at ISO 100, which helps set expectations for coverage. For many photographers, that makes the F1s best suited for subtle extra light, like filling shadows on street portraits, casual indoor scenes, or as an easy way to improve visibility when available light drops.
It is also rated for high-speed sync up to 1/500s, which can be useful when you want to keep shutter speeds high. The tradeoff is output limitations, so it is not the right choice if you expect it to light subjects from far away or bounce heavily off large surfaces.
Battery and charging
The flash includes a built-in 3.7V/128mAh lithium-ion battery. Charging uses a Type-C interface, which is convenient for travel since many photographers already carry USB-C cables. The flash’s recycling time is listed as approximately 6 seconds, and recharge time is listed around 1 to 1.5 hours (depending on your charger output).
Compatibility checklist (this is the make-or-break)
This is a single-contact hot-shoe flash. That matters more than brand names. It is marketed for several camera lines, including Ricoh GR3/GR3X, Sony ZV1 (and ZV-E10), Fujifilm, Olympus, Nikon, and Canon cameras, but there are important exclusions.
Look for a single-contact hot shoe
If your camera has a single-contact hot shoe, this flash is the type of device that is commonly used. If your camera uses a more complex multi-pin hot-shoe system, compatibility may not work the way you expect.
Known incompatibilities to avoid
It is specifically noted as not compatible with Sony ZV-1F, and certain Canon models such as EOS Rebel SL3/250D, Rebel T7/1500D, 2000D, and models in the Rebel T100/3000D/4000D/200DII line. Because hot-shoe standards vary, it is smart to confirm your exact camera model and hot-shoe type before purchasing.
Using it with lenses, including shadow caveats
The flash mounts in a fixed position relative to the camera, so larger lenses and lens hoods can sometimes intrude into the light path. This can create shadows on your subject, particularly at close distances. If you mostly shoot with compact, pancake-style lenses, you are more likely to get clean, consistent fill lighting.
Who should buy it
- You want a compact hot-shoe flash for Ricoh GR-style travel photography and casual fill lighting.
- You prefer simple controls (a single gear setting) and quick setup over menu-heavy systems.
- You value USB-C charging and the convenience of a built-in rechargeable battery.
- You want high-speed sync up to 1/500s for daytime shutter speed control, as long as you understand the power limitations.
Who should skip it
- You need stronger output for long distances or low-light work where the flash must do most of the lighting.
- Your camera is not single-contact hot-shoe compatible, or it is one of the specifically noted incompatible models.
- You plan to shoot mostly with larger lenses and hoods where shadowing is a concern, and you do not want to manage the placement tradeoffs.
Alternatives to consider
If your top priority is reach, consider shoe-mount flashes with higher guide numbers and more flexible power options (for longer working distances or bouncing). If your priority is ultra-simplified use for video or mixed shooting, another category option is an on-camera light designed primarily for continuous illumination, since they are not constrained by flash output the same way. If your priority is compatibility, your best “alternative” may be picking a flash explicitly matched to your camera’s hot-shoe standard, especially for models with known multi-pin requirements.

FAQ
Is the MEDALight F1s mini flash compatible with all hot-shoe cameras?
No. It is intended for cameras with a single-contact hot shoe. Some models are specifically noted as not compatible, including Sony ZV-1F and certain Canon Rebel lines.
How strong is the flash for low-light photography?
The flash is designed for compact fill-light use. It has a listed guide number of GN5 (ISO 100) and a recommended range up to about 4m, so it may feel underpowered for long-distance or very low-light situations.
Does it use replaceable batteries?
No, it has a built-in rechargeable 3.7V/128mAh lithium-ion battery. You recharge via the Type-C port.
What is the flash’s high-speed sync rating?
It is rated for high-speed sync up to 1/500s.
Can lens hoods block the light?
Yes. Because the flash sits in a fixed position on the hot shoe, larger lenses and lens hoods can cast shadows on the subject. Compact lenses tend to work better.

Nikon SB-700 AF Speedlight Flash for Nikon Digital SLR Cameras, Standard Packaging
The Nikon SB-700 is a compact, feature-rich shoe-mount flash built for Nikon Creative Lighting System (CLS) users who want more than a built-in flash, plus reliable wireless control. Expect fast recycle times, strong i-TTL performance on compatible Nikon DSLRs, and useful onboard diffusion and filters, with the main caveat being compatibility limits outside Nikon CLS ecosystems.
Godox IT32 TTL Camera Flash with X5L Flash Trigger for Leica Cameras
The Godox IT32 TTL mini flash with the X5L trigger is a compact 2-in-1 on-camera flash and off-camera wireless trigger system built for Leica M-series cameras. 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.

The Godox iM30 mini manual flash is a compact, hot-shoe flash with 7 manual power levels and a fixed, front-facing head. It is well suited to travel, fill light, and short lenses, but it does not support TTL and can cast shadows with larger lenses or hoods. It runs on two AAA batteries (not included), and compatibility depends on having a central-pin hot shoe.
