Nikon Coolpix P1100 (Black)

Shoot at staggering distances with the 125x optical zoom COOLPIX P1100 Digital Camera from Nikon. This camera has a 16MP backside illuminated CMOS sensor and features a built-in NIKKOR lens with a 35mm equivalent focal length range of 24-3000mm. You can zoom even further with 250x Dynamic Fine digital zoom, which gives you an equivalent focal length of 6000mm. Coupled with these extreme focal lengths is Nikon's Dual Detect Optical Vibration Reduction, which provides four stops of optical image stabilization, ensuring your telephoto shots are crisp and drastically reducing camera shake during handheld shooting. Gracing the back of the camera is a 3.2" vari-angle, 921k-dot LCD monitor and an eye-level 2.36m-dot electronic viewfinder, so your subjects will always be easy to see. The camera is also capable of recording 4K UHD video at 30 fps and supports an external microphone via a 3.5mm connector. 16MP BSI CMOS Image Sensor The backside-illuminated sensor with 16 million effective pixels can output detailed images at sensitivities between ISO 100 and 6400 and allows for captures in the newly introduced RAW (.NRW) format. 125x Optical Zoom with Dual Detect Optical Vibration Reduction An absurd 24-3000mm (35mm equivalent) focal range means few, if any, objects are out of reach. Zoom is further enhanced by Dynamic Fine digital zoom, which makes the maximum focal length a ridiculous 6000mm. Dual Detect Optical Vibration Reduction provides four stops of optical image stabilization, so your handheld shots are crisp.

Apple AirPods Max - Silver | Wireless Bluetooth Headphones

Manufacturer's description: Discover a new era of flawless audio with the AirPods Max. Machined aluminium ear cups connect by a unique suspension system, enabling independent articulation to the telescoping arms of the headband. These components work in harmony to maintain an exceptional over-ear seal; the foundation for its incredible sound. Custom drivers deliver high-fidelity playback with ultra-low distortion across the entire audible range. A pair of Apple-designed H1 chips allow computational audio features like Adaptive EQ, which tailors sound to your bespoke fit by measuring and then adjusting what you're hearing up to 200 times per second. Active Noise Cancellation uses eight microphones positioned to sense and block noise from any direction. A single button press activates Transparency mode, letting you hear what's around you. Spacial audio tracks head movement for immersive, theatre-like sound. The Digital Crown allows precise control of volume and playback. Enjoy up to 20 hours of listening time with this magical audio experience that sets a new standard for over-ear headphones. The over-ear headphone has been completely reimagined. From cushion to canopy, AirPods Max are designed for an uncompromising fit that creates the optimal acoustic seal for many different head shapes - fully immersing you in every sound. The canopy spanning the headband is made from a breathable knitted mesh, distributing weight to reduce on-head pressure. The stainless steel frame is wrapped with a soft-to-the-touch material for a remarkable combination of strength, flexibility and comfort. Telescoping arms smoothly extend and stay where you set them, for a consistent fit and seal. The beautifully anodised aluminium cups feature a revolutionary mechanism that allows each cup to rotate independently and balance pressure. A custom-designed mesh textile wraps the ear cushions to provide pillow-like softness while listening. Crafted with acoustically engineered memory foam, the ear cushions gently create an immersive seal that is the foundation of incredible sound. The Digital Crown lets you precisely control volume, skip between tracks, answer phone calls and activate Siri. AirPods Max combine high-fidelity audio with industry-leading Active Noise Cancellation to deliver an unparalleled listening experience. Each part of their custom-built driver works to produce sound with ultra-low distortion across the audible range. From deep, rich bass to accurate mids and crisp, clean highs, you'll hear every note with a new sense of clarity. To cancel unwanted external sound, AirPods Max use a total of six outward-facing microphones to detect noise in your environment, and two inward-facing microphones to measure what you're hearing. Beamforming microphones help isolate your voice on phone calls. The Apple-designed dynamic driver produces a wide frequency range that uncovers the rich details of every sound — delivering your favourite songs with previously unheard texture and accuracy.

OnBuy shows limited transparency regarding their environmental and social practices. While they have basic seller vetting processes, they lack clear sustainability initiatives and published ESG goals. The marketplace model makes it difficult to control the environmental impact of shipping and packaging. They have made some progress in reducing digital carbon footprint but need significant improvement in sustainable business practices and ethical sourcing guidelines.
