Clear- The "mount" is the system that connects the lens to the camera. Each camera has its own mount (e.g., Canon EF, Sony E). To find the mount of their camera, one simply needs to check its specifications and choose a lens with the same mount.
- Full Frame: Camera lenses intended for use with full frame sensor cameras. Used for portrait photography, landscape, and other demanding applications.
- Crop Frame: Lenses intended for use with cameras that have a crop frame sensor (smaller frame). Ideal for general photography, portraits, and sports photography, as they provide a greater focal length, suitable for distant shots or zoom.
- Medium Format: Camera lenses intended for use with medium format cameras (larger than full frame). These lenses offer excellent resolution, depth of field, and color accuracy, making them ideal for professional photography.
- Fixed Focal Length: Lenses with a fixed focal length, also known as "prime" lenses, that cannot zoom (change the frame size) but offer better image quality. Ideal for portraits and low-light photography.
- Fixed Aperture Zoom: Lenses where the minimum aperture value remains the same (constant brightness) as the zoom increases. Ideal for low-light photography and professional applications.
- Variable Aperture Zoom: Lenses where the minimum aperture value changes (brightness decreases) as the zoom increases. Ideal for general photography, travel photography, and everyday shots.
- AutoFocus: Automatic focus mode. Particularly useful for photographing subjects in motion (e.g. children playing).
- Image Stabilization: Function for less shaky photos and videos with handheld shots, especially in low light conditions.
- Macro: Lenses with the ability to photograph subjects from very close distances.
- Fisheye: Ultra-wide lenses with a shooting angle close to 180° and strong distortion effects.
- Pancake: Lenses with particularly small size, for easy transport and more discreet use.
- Tilt-Shift: Lenses with perspective correction capability. Mainly for architectural photography.
- f/1.2: Extremely bright aperture for very low light and strong background blur (bokeh).
- f/1.4: It is a very bright maximum aperture, allowing more light to enter the sensor, ideal for low-light shooting
- f/1.8: Very bright aperture, ideal for portraits and shooting in low light conditions.
- f/2: It is a fairly bright maximum aperture, allowing for good shots in low light and offering good subject isolation.
- f/2.8: It is a bright aperture, particularly common in professional zoom lenses. It offers good performance in low light and satisfactory bokeh effect.
- f/3.5: Balanced choice for general photography with good brightness and greater depth of field.
- f/4: It is a medium aperture often used in zoom lenses for flexibility and portability. It provides satisfactory performance in good lighting, but in low light, a higher ISO or lower shutter speed may be needed.
- f/4.5: Smaller maximum aperture, suitable for shots with greater depth of field and good lighting.
- f/5.6: It is a smaller aperture that offers greater depth of field, making it ideal for landscapes and product photography, where more sharpness is required throughout the frame.
- Ultra Wide Angle: With a focal distance of up to 24mm and a focus primarily on landscape and architectural photography.
- Wide Angle: With a focal distance of 24mm to 35mm, there is a slight distortion and elements appear longer than they actually are.
- Telephoto: With a focal distance of 100mm to 300mm, they are ideal for photographing a distant object due to the high magnification they provide.
- Hyper-Telephoto: With a focal distance greater than 300mm, the highest magnification of objects is achieved and they are mainly used in wildlife photography or wherever large distances are necessary.
- Small Telephoto Lens: Focal lengths ranging from 70mm to 100mm are a popular choice for portraits, as they compress perspective and achieve subject isolation from the background.
- Standard: With a focal distance of 40mm to 60mm approaching the angle of human eye view, they are the most common and useful for general photography.
- 70 - 200mm: Telephoto lens ideal for portraits, sports, and distant subjects with long focal length.
- 70 - 300mm: Larger telephoto lens for wildlife, sports, and distant subjects.
- 24 - 70mm: Very versatile lens for everyday use, portraits, and landscapes.
- 24 - 105mm: Slightly wider range for travel and general photography, covers portraits, landscapes, and more distant subjects.
- Video Production: Lenses for video with fixed focus and image stabilization capability, ideal for filmmaking.
- Landscape Photography: Lenses for landscape photography, with a wide field and small aperture for large focus areas and clarity.
- Wildlife & Sports Photography: Lenses for wildlife and sports photography, with long focal lengths and fast focusing.
- Portrait Photography: Lenses ideal for portraits with a large aperture for beautiful background blur.
