The pixel error of a camera is typically due to the camera sensor rather than the lens or the camera body. The sensor is responsible for capturing the image and any defects or issues with the sensor can result in pixel errors. However, it's also important to ensure that the lens is clean and free from any defects that could impact image quality. In some cases, issues with the camera body such as faulty connections or processing errors can also contribute to pixel errors. **

The pixel error on your camera is most likely due to an issue with the camera sensor or image processing system within the camera body, rather than the lens. The lens is responsible for focusing light onto the sensor, but pixel errors typically stem from problems within the camera's internal components. It is recommended to consult with a professional technician or the camera manufacturer for a proper diagnosis and repair. **

No, you cannot create a 1080-pixel stream with a 720-pixel camera. The resolution of the camera determines the maximum quality of the video it can capture. In order to create a 1080-pixel stream, you would need a camera that is capable of capturing video at that resolution. Using a 720-pixel camera would result in a lower quality stream. **

A prime lens with a focal length between 35mm and 50mm is typically considered suitable for street photography. These lenses offer a natural field of view that closely resembles what the human eye sees, making them great for capturing candid moments in urban environments. Additionally, prime lenses are often compact and lightweight, which is ideal for street photographers who need to move quickly and discreetly. Overall, a 35mm or 50mm prime lens is a popular choice among street photographers for its versatility and ability to capture authentic moments. **

A macro lens is typically the best choice for product photography. Macro lenses are designed to capture small subjects with great detail and clarity, making them ideal for capturing the intricate details of products. They also have a close focusing distance, allowing you to get up close to the product for detailed shots. Additionally, a lens with a focal length between 50mm and 100mm is recommended for product photography as it provides a natural perspective and minimizes distortion. **

For animal photography, a camera with a fast autofocus system and high burst rate is essential to capture fast-moving subjects. A good choice would be a DSLR or mirrorless camera with at least 20 megapixels for high-quality images. As for the lens, a telephoto lens with a focal length of 70-200mm or longer is recommended to get close-up shots of animals without disturbing them. Additionally, a lens with image stabilization can help reduce camera shake when shooting handheld in low light conditions. **

For wildlife photography, a camera with a fast continuous shooting speed, high resolution, and good low-light performance is ideal. Cameras like the Canon EOS 90D, Nikon D500, or Sony Alpha a6600 are popular choices. When it comes to lenses, a telephoto lens with a focal length of at least 300mm is recommended to capture distant wildlife without disturbing them. Lenses like the Canon EF 100-400mm f/4.5-5.6L IS II, Nikon AF-S NIKKOR 200-500mm f/5.6E ED VR, or Sony FE 200-600mm f/5.6-6.3 G OSS are great options for wildlife photography. **

You can increase the pixel size of a photo using photo editing software such as Adobe Photoshop or GIMP. In these programs, you can use the "Image Size" or "Canvas Size" options to increase the pixel dimensions of the photo. Keep in mind that increasing the pixel size of a photo may result in a loss of image quality, so it's important to use this feature carefully and consider the impact on the overall image. **
