A zoom lens is generally better suited for wildlife photography because it offers versatility in framing the subject without having to physically move closer or further away. This is especially important when photographing unpredictable wildlife in their natural habitat. However, a prime lens can also be effective for wildlife photography, particularly for capturing specific details or in situations where a lighter and more compact lens is preferred. Ultimately, the choice between a prime lens and a zoom lens for wildlife photography depends on the specific needs and preferences of the photographer. **

A fast telephoto lens with a wide aperture, such as a 70-200mm f/2.8, is suitable for indoor sports photography. This type of lens allows you to capture fast-moving subjects in low light conditions, which is often the case in indoor sports venues. The wide aperture also helps to create a shallow depth of field, isolating the subject from the background and creating a more dynamic and professional-looking image. Additionally, the telephoto focal length allows you to zoom in on the action from a distance, without being too intrusive to the athletes or disrupting the game. **

For sports photography, a telephoto lens with a focal length of at least 200mm is suitable. This will allow you to capture action from a distance and isolate your subject from the background. A lens with a wide aperture, such as f/2.8, will also be beneficial for capturing fast-moving subjects in low light conditions. Additionally, consider a lens with image stabilization to help reduce camera shake when shooting handheld. **

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. **

A telephoto lens with a focal length of at least 200mm is suitable for sports photography in motocross. This type of lens allows the photographer to capture the action from a distance, while still maintaining a close-up view of the subject. Additionally, a lens with a wide aperture, such as f/2.8, is beneficial for capturing fast-moving subjects in low light conditions. Overall, a telephoto lens with a wide aperture is the best choice for capturing the fast-paced and dynamic nature of motocross sports photography. **

A 300mm zoom lens may not be sufficient for planetary photography as planets are very far away and appear small in the night sky. To capture detailed images of planets, a telescope with a high magnification power would be more suitable. However, a 300mm lens could still be used to capture wide-angle shots of the night sky or to photograph the moon. **
