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. **

In terms of temperature gradation, the designation Fahrenheit is not more precise than Celsius. Both Fahrenheit and Celsius scales have the same degree of precision, with one degree difference in Fahrenheit being equivalent to 0.55 degrees in Celsius. The difference lies in the starting point and the size of the degree intervals. While Fahrenheit has smaller degree intervals, it does not make it more precise in terms of temperature gradation compared to Celsius. **

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. **

No, the designation Fahrenheit is not more precise in terms of temperature gradation than degrees Celsius. Both Fahrenheit and Celsius use the same interval size for temperature gradation (1 degree), but they have different starting points. Fahrenheit starts at 32 degrees for the freezing point of water and 212 degrees for the boiling point of water, while Celsius starts at 0 degrees for the freezing point of water and 100 degrees for the boiling point of water. **

The Fahrenheit scale is not necessarily more accurate in terms of gradation for temperatures than Celsius. Both Fahrenheit and Celsius are equally accurate in measuring temperature, but they have different reference points and scales. The Fahrenheit scale is commonly used in the United States, while the Celsius scale is used in most other countries and in scientific settings. Ultimately, the choice between Fahrenheit and Celsius comes down to personal preference and familiarity with the scale. **

The best camera for wildlife photography is typically a DSLR or mirrorless camera with a high resolution sensor, fast autofocus system, and good low-light performance. Popular choices include the Canon EOS 5D Mark IV, Nikon D850, or Sony A7R IV. For lenses, a telephoto lens with a focal length of at least 300mm is recommended for capturing wildlife from a distance. Some popular options include the Canon EF 100-400mm f/4.5-5.6L IS II, Nikon AF-S 200-500mm f/5.6E ED VR, or Sony FE 100-400mm f/4.5-5.6 GM OSS. Ultimately, the best camera and lens will depend on your budget, specific needs, and personal preferences. **
