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. **

Squids belong to the group of animals known as cephalopods, which also includes octopuses and cuttlefish. These animals have well-developed lens eyes that are similar in structure to vertebrate eyes. The lens in their eyes helps to focus light onto the retina, allowing them to see and navigate their environment effectively. **

One can do moon photography with a Lumix MFT camera using a telephoto lens with a focal length of at least 200mm. This will allow for capturing the details of the moon's surface and its craters. Additionally, using a teleconverter can further extend the focal length for even closer shots of the moon. It's important to use a sturdy tripod to minimize camera shake and achieve sharp images. **

Red eyes in a photo are typically caused by the camera flash reflecting off the blood vessels in the back of the eye. This reflection occurs when the flash is too close to the camera lens, causing the light to bounce directly back into the lens. To avoid red eyes in photos, you can try using red-eye reduction mode on your camera or have the subject look slightly away from the camera to reduce the reflection. Additionally, editing software can be used to correct red eyes in post-processing. **
