Lenses are a collection of parts used to create images on film or sensor. The better the glass quality, the better the lens. The quality of lenses in photography is directly proportional to the quality of photography. The photography is light. It is the aperture that controls the light. It is located in our lenses. So let’s talk about types of lenses.
When a person closes one eye and looks at a fixed point with the other eye. In other words, when aiming with a military expression, the angle of view is 46 degrees. The angle of view of a 50mm lens is 46 degrees. That’s why 50mm lenses are expressed as normal, below this value as wide, and above it as a narrow angle. Note that these values are for full frame machines. On Aps-c machines, these values change due to the crop factor.
The lenses are classified according to their viewing angles. Here are the all types of lenses.
Standard (Normal) Lenses
The viewing angles are the closest to the human eye (45-50 degrees). Image size 24 × 36 mm. and 50 mm. focal length lenses are normal lenses. 7-21 mm lenses for digital cameras can be considered normal lenses. The best quality results are obtained with normal lenses.
Wide Angle Lenses
The angle of view of wide-angle lenses is widening compared to normal lenses, increasing the depth of field. They are commonly used to obtain the widest image in very narrow areas. They can create distortion in the corners and edges of the image obtained at focal lengths below 35 mm. However, some photographers can use this distortion effect as an aesthetic value. The lenses between 17-28mm. are wide-angle lenses.
Fisheye Lenses provide the widest viewing angle. In images obtained using such lenses, vertical and horizontal lines are significantly distorted, near-circular images are obtained. These are lenses between 6 and 16 mm, which are very helpful in achieving creative images.
Narrow Angle (Tele) Lenses
They are lenses whose angle of view is narrower than normal lenses. It is used for shooting subjects such as portrait, sports, nature or birds that cannot be approached much. 100, 200, 300, 400 mm. are lenses with focal length.
They are lenses that features more than one different lens. It was produces for the difficulty of carrying too much objective and frequent replacement. These lenses, whose focal length and the angle of view are changed by turning the ring back and forth or right and left, have been used quite widely in recent years. The zoom lenses developed for general use provide the user with ease of framing.
They are very high-quality and expensive lenses that can magnify the subject by 1/2 (x0.5) or 1/1 (x1). They are produced in three separate focal lengths, 50, 100 and 200 mm. Nikon has 55, 105 and 200 mm lenses. The 55mm lens provides 1/2 magnification and this is sufficient to magnify the flower. But if you want to work in a field that won’t scare off insects and butterflies, you should use a 105 or 200mm macro lens.
Photo Stabilizer Lenses
These lenses largely prevent distortion of the photo due to shaking of the hand, thus allowing slower shutter speeds. It is especially useful in nature photographs. Prices are quite expensive. Each brand has also named this feature in its own way. Named the feature of anti-vibration with abbreviations such as Nikon – VR, Canon – OS, Sigma – OS, Tamron – VC. Some camera manufacturers have placed the anti-vibration feature on the body of the camera. Like Sony, Pentax, Olympus.
Yes friends, that’s all about types of lenses. if we want to take clear and sharp photos, let’s not forget that we should choose our lens well.
