Generally, choosing a long focal length lens, like 70mm, 135mm, or 200mm, is wise to isolate textures and distant features to create dramatic backgrounds. Wide focal length lenses, like 16mm, 24mm, or 35mm, thrive when you want the entire scene in focus, like when shooting simple landscapes with long leading lines.

Lens compatibility is another consideration; full-frame lenses can be used on both sensor types, but APS-C lenses on full-frame bodies may result in vignetting. Finally, while full-frame cameras are more expensive, they are preferred for their superior image quality and flexibility in various shooting conditions. Conversely, due to the crop factor, APS-C cameras are favored for their affordability, compactness, and built-in telephoto advantage, making them a versatile choice for many photographers.

Then there's the standard lens, around 50mm, often hailed as the "nifty fifty." It’s akin to the human eye in how it captures the world, making it incredibly versatile. It’s perfect for everyday shooting and portraits, blending background and foreground elements naturally. As a beginner, using a 50mm lens encourages you to physically move around, engaging more with your environment, which can lead to more thoughtful compositions.

Let’s break it down: Wide-angle lenses (under 35mm) are your go-to for capturing vast landscapes and bustling street scenes. They fit more into the frame, which is great for sweeping views and architectural photography. Meanwhile, telephoto lenses (over 70mm) excel in bringing distant subjects into sharp relief. They're ideal for zeroing in on distant details, perfect for sports or wildlife photography, and they add a dramatic flair by compressing space, making elements in the photo appear closer together.

On the other hand, the smaller APS-C sensors come with a "crop factor" of about 1.5x to 1.6x, effectively increasing the focal length of lenses and providing extra "reach," which can be beneficial for telephoto photography such as sports or wildlife. Despite potentially higher noise levels in low light, APS-C cameras offer a more compact and affordable option for those seeking a balance between performance and portability. This makes them attractive to amateurs, enthusiasts, and even professionals who value a lighter system.

Lastly, fisheye lens are a super fun addition to the camera bag if you’re into the widest view possible. Their angle of view is usually 180°, allowing you to see half of a full rotation and offering a distinctive, hemispherical lens distortion. They cram in as much information as possible; thus, they don’t produce straight lines. These are awesome for creative, experimental photography projects, especially within fashion portraits or skateboarding content.
