Nikon Nikkor Z 400mm F/4.5 VR Lens
Long Reach, Compact Design
![](https://static.bhphoto.com/images/rich_content/desktop/IMG_1783262.jpg)
- Sophisticated optical design includes a series of specialized elements that promote a lighter, more compact overall design.
- Modest f/4.5 maximum aperture offers a practical balance between size, speed, and weight.
- With a size more akin to a 70-200mm f/2.8, this lens measures just 9.2" long and weighs 2.7 lb. Compared to the Z 400mm f/2.8 lens, this f/4.5 version weighs 3.8 lb less and measures 6" shorter in length.
S-Line Optics

- Helping to virtually eliminate chromatic aberrations, color fringing, and comatic aberrations, this lens features one ED (extra-low dispersion) glass element and two Super ED elements, along with one SR (short-wavelength refractive) element.
- The SR element features a specialized high-dispersion design that refracts wavelengths shorter than blue; this helps achieve truly accurate color rendering and also aids in making the lens design more compact.
- Nano Crystal Coat has been applied for well-rounded anti-glare protection at all angles, helping to suppress ghosting, reflections, and flare for higher contrast and more accurate color response when working in strong lighting and backlit conditions.
Autofocus and Vibration Reduction

- Advanced autofocus system uses stepping motors to deliver quick and accurate focusing performance, along with smooth and quiet AF that is well-suited to both stills and video applications.
- Full-time manual focus override is also possible and an internal focusing design is used, where only the internal lens groups are moved during focusing, to maintain the overall length of the lens during use and to promote faster focusing speeds.

- Vibration Reduction image stabilization reduces the appearance of camera shake by approximately 5.5 stops to better enable handheld shooting in low-light situations.
- Synchro VR is also supported when paired with compatible cameras featuring sensor-shift VR, which combines in-body VR with optical VR for improved results of up to 6 stops of compensation.
Professional Handling and Construction

- As part of the lightweight, nimble design, the included tripod foot can easily be removed for a slimmed down design that's ideal for handheld use.
- Physical design focuses the center of gravity toward the rear of the lens, around the tripod mount, for smoother, more responsive panning when shooting handheld or working atop a tripod or monopod. The tripod mount also rotates for easier switching between vertical and horizontal shooting orientations.
- Intuitive "no-look" control layout puts all of the frequently-used buttons and dials in easy-to-reach locations to prevent the need to move your eye from the viewfinder.
- Front anti-slip rubber grip for stable handheld use.
- Separate manual focus ring and a programmable control ring offer distinct levels of tactile control over shooting settings.
- Compatible with optional Z-Teleconverter TC-1.4x and TC-2x to further extend the reach of this lens.

- Weather-sealed design includes rubber gaskets to prevent dust and moisture ingress and the exposed elements have a fluorine coating that repels dirt and oils and is easier to clean.
- Store a focusing position using the Memory Set button so you can instantly return to this by position by pressing the Fn or Fn2 buttons—perfect for capturing fleeting movements.
- Two customizable L-Fn buttons can be set to configure subject tracking, AF lock, image playback, or other modes. The L-Fn2 button is also accessible from four different locations on the barrel for easy reach.
- Focus limiter switch can constrain the focus range to 19.7' to infinity or from the full focusing range of 8.2' to infinity.
- Programmable Control Ring can also be used to control aperture, ISO, or exposure compensation.
- Kensington lock support for securing the lens in place during remote shooting sessions.
- Uses front screw-in 95mm filters.

Tips for protecting your children online
In today's digital age, ensuring your children's safety while they browse the internet is paramount. As they explore the vast online world through smartphones, gaming consoles, laptops, and other devices, it's essential to implement measures to shield them from potentially harmful content and interactions. Here are some tips to help you safeguard your children online:
1. Communication is Key
Open and ongoing communication with your children about online safety is crucial. Discuss the potential dangers they may encounter online, such as pornography, cyberbullying, and violent content. Encourage them to come to you with any concerns or questions they may have.
2. Set Clear Boundaries
Establish clear rules and boundaries regarding internet usage. Define appropriate time limits for browsing and specify which websites and apps are off-limits. Make sure your children understand the consequences of violating these rules. You can also restrict some of these apps or online content utilising device level parental controls explained below.
3. Utilise Parental Controls
Take advantage of the parental control features available on devices and internet browsers. These controls allow you to block access to specific websites, set age-appropriate content filters, and monitor your children's online activities. Familiarise yourself with the parental control options on smartphones, gaming consoles, and laptops to effectively manage your children's online experiences.
4. Educate Yourself
Stay informed about the latest trends and technologies related to online safety. Familiarise yourself with popular social media platforms, gaming communities, and messaging apps that your children may use, including the functions they provide. This knowledge will help you understand the potential risks and take appropriate action to protect your children.
5. Monitor Their Online Activities
Regularly monitor your children's online activities to ensure they are adhering to the rules and staying safe. Keep an eye on their browsing history, social media interactions, and messaging apps. Be vigilant for any signs of cyberbullying or exposure to inappropriate content.
6. Encourage Safe Online Behavior
Teach your children about the importance of practicing safe online behavior. Remind them never to share personal information, such as their full name, address, or phone number, with strangers online. Encourage them to think critically about the content they encounter and to report anything that makes them feel uncomfortable or unsafe.
7. Lead by Example
Be a positive role model for your children by demonstrating responsible and respectful online behavior yourself. Show them how to navigate the internet safely and responsibly, and emphasize the importance of treating others with kindness and empathy online.
8. Reporting abuse, making complaints and finding more information
For additional resources and guidance on online safety, visit the Australian e-Safety Commissioner's website at www.esafety.gov.au. Here, you'll find a wealth of information, including tips for parents, educational resources for children, and tools for reporting online abuse and harassment.
You can also report abuse through the website’s online form.

Remember, proactive measures and open communication are key to fostering a safe and positive online environment for your family.
