A camera lens is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media. Lenses are the key component in a camera, allowing it to focus light and produce an image. Without a lens, a camera is little more than a light-tight box.
There are three main types of camera lenses:
-The standard lens has a focal length between 40 m m and 60 m m on full frame cameras, and between 28 m m and 45 m m on APS-C cameras. Standard lenses are versatile; they’re great for everything from street photography to portraiture to landscape photography.
-The telephoto lens has a focal length greater than 60 m m on full frame cameras, and greater than 45 m m on APS-C cameras. Telephoto lenses are great for sports photography, wildlife photography, and portrait photography where you want to compress the background relative to the subject.
-The wide angle lens has a focal length less than 40 m m on full frame cameras, and less than 28 m m on APS-C cameras. Wide angle lenses are great for landscape photography, cityscape photography, architectural photography, and real estate photography.
1 The Mighty 50 m m. If you only have budget for one extra lens, make it a 50 m m
50 m m lenses are incredibly versatile, and are suitable for a huge range of different photography genres. Whether you shoot landscapes, portraits, or street photography, a 50 m m lens is a great option to consider.
One of the main benefits of 50 m m lenses is that they offer a very natural field of view. This means that images taken with a 50 m m lens will look very similar to what your eyes see. This can be extremely beneficial for shooting candid shots, as your subjects won’t be aware that they’re being photographed.
Another big advantage of 50 m m lenses is that they tend to be very small and lightweight. This makes them ideal for situations where you need to travel light, such as when hiking or backpacking. They’re also much less expensive than some of the larger DSLR lenses on the market.
If you’re looking for an all-purpose lens that offers excellent value for money, then a 50 m m lens is definitely worth considering.
3 The Magical Macro
The world is a beautiful place, and there’s no better way to explore it than through macro photography. Whether you’re shooting flowers, insects, or other small objects, macro lenses let you get up close and personal with your subject matter.
There are three essential macro lenses that every photographer should have in their camera bag:
The first is a standard macro lens with a focal length of around 100mm. This is the ideal lens for general purpose macro photography, as it offers a good balance between magnification and working distance (the distance between the front of the lens and your subject).
The second is an extreme macro lens with a focal length of around 50 m m. This lens provides much more magnification than a standard macro lens, allowing you to capture details that would otherwise be invisible to the naked eye. However, it has a very short working distance, so you’ll need to get very close to your subject matter when using this lens.
The third essential macro lens is a telephoto macro lens with a focal length of around 200mm. This longer focal length gives you more distance from your subject, which can be useful when shooting skittish insects or other wildlife. It’s also helpful for photographing large subjects (such as flowers) that wouldn’t fit within the frame at shorter focal lengths.
No matter what type of photography you’re interested in, having at least one of these three essential macros lenses will give you the ability to capture stunning close-up images.
