Review NEEWER Ttl Flash Speedlite Hss Optical Slave Rear Curtain Sync

The Neewer NW-645II-N TTL Flash Speedlite, model number 10102194, is a versatile and powerful accessory for photographers looking to enhance their lighting setup. This flash boasts a Guide Number (GN) of 58 at ISO 100 and 200mm, making it suitable for a wide range of photography scenarios, from portraits to landscapes.

This flash is a TTL (Through-The-Lens) type, which means it communicates with your camera to automatically adjust the flash output based on the camera settings and lighting conditions. This results in more accurate and consistent exposures, saving you time and effort in post-production.

The Neewer NW-645II-N also features high-speed sync (HSS) capabilities, allowing you to shoot at shutter speeds faster than the flash's recycle time. This is particularly useful when photographing moving subjects or when you want to use a wide aperture to create a shallow depth of field.

This flash also comes with an optical slave mode and a rear curtain sync function. The optical slave mode allows the flash to be triggered wirelessly by other flashes or studio strobes. The rear curtain sync function, also known as second curtain sync, produces a trailing light effect by firing the flash at the end of the exposure, rather than at the beginning.

The Neewer NW-645II-N has a robust build, with a sturdy metal exterior and a durable LCD screen that displays essential information such as battery level, flash mode, and zoom setting. It also features a tilting head that can be adjusted from -75 to 90 degrees, allowing you to bounce or swivel the light to create soft and even illumination.

The flash is powered by four AA batteries, which can be easily accessed by removing the bottom plate. It also comes with a conveniently located LCD screen for displaying battery level and other settings. The flash has a recycle time of approximately 2.5 seconds at full power, and a flash duration of 1/250 second at full power.

The Neewer NW-645II-N TTL Flash Speedlite is a must-have accessory for any photographer looking for a reliable and versatile flash with advanced features. Whether you're a seasoned pro or just starting out, this flash is sure to help you capture stunning and well-lit images.

Newer NW-645II-N TTL Flash Speedlite: A Comprehensive Analysis

The Newer NW-645II-N TTL Flash Speedlite is a popular and affordable off-camera flash option for photographers. Here are some pros and cons to help you make an informed decision about whether this flash is right for you.

1. Affordable: This flash is priced at a fraction of what some of the more well-known brands charge, making it an excellent option for those on a budget.

2. TTL and Manual Modes: With both TTL (Through-The-Lens) and manual modes, this flash offers flexibility to adjust exposure as needed.

3. HSS (High-Speed Sync): HSS allows for the use of flash in bright daylight or when using wide apertures, which can be especially useful in outdoor photography.

4. Optical Slave: The flash includes an optical slave function, which allows it to fire based on the light detected from another flash or the camera's built-in flash.

5. Rear Curtain Sync: This feature can create interesting effects when photographing moving subjects by syncing the flash with the rear curtain of the shutter.

6. Decent Recycle Time: With a recycle time of approximately 3 seconds at full power, this flash is relatively quick compared to some other entry-level options.

1. Limited Power: The flash has a Guide Number (GN) of 58, which is average for an entry-level flash but may not be sufficient for larger venues or subjects.

2. Build Quality: The flash's construction is primarily plastic, which may not be as durable as more expensive options.

3. No Wireless Control: Unlike some more advanced flashes, this one does not have built-in wireless control, requiring the use of an external trigger or the optical slave function.

4. Limited Mounting Options: The flash comes with a standard hot shoe mount, but it does not include a bracket for bounce or swivel functionality.

The Newer NW-645II-N TTL Flash Speedlite is an excellent entry-level flash for those looking for an affordable off-camera lighting solution. It offers features like TTL and manual modes, HSS, optical slave, and rear curtain sync, making it a versatile tool for various photography scenarios. While it has some limitations, such as limited power and build quality, these issues are to be expected given its affordable price point. Ultimately, if you are looking for a cost-effective flash to expand your photography capabilities, the Newer NW-645II-N TTL Flash Speedlite is a solid choice.

If you are a beginner photographer on a tight budget or an experienced photographer who wants a backup flash, the Newer NW-645II-N TTL Flash Speedlite is worth considering. It offers a good balance of features, performance, and affordability. However, if you require a more powerful flash or advanced features, you may want to consider investing in a more expensive option.
