Compatibility (Mount): 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 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.
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.
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.
Wide Angle: With a focal distance of 24mm to 35mm, there is a slight distortion and elements appear longer than they actually are.
Ultra Wide Angle: With a focal distance of up to 24mm and a focus primarily on landscape and architectural photography.
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.
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.
