The Kamlan 28mm F1.4 lens is a manual focus lens designed for Micro Four Thirds mount cameras. It is a prime lens with a fixed focal length of 28mm and a maximum aperture of f1.4, which makes it a great choice for low light photography and creating a shallow depth of field.
The lens has a compact design with a diameter of 55mm and a length of 65mm. It weighs 384 grams and has a filter diameter of 52mm. The lens is constructed with 8 elements in 7 groups, which helps to reduce aberrations and provide good image quality.
The Kamlan 28mm F1.4 lens does not have autofocus capabilities, which means that you will need to focus the lens manually. While manual focus may take some getting used to, it can be beneficial for achieving precise focus and creative control.
The lens does not have optical image stabilization, which means that you will need to use a tripod or other stabilization methods if you are shooting in low light or at slower shutter speeds. However, the wide maximum aperture of f1.4 can help to compensate for this, allowing you to shoot at faster shutter speeds.
The lens has a minimum focus distance of 25cm, which means that you can get close to your subject and achieve a shallow depth of field.
Overall, the Kamlan 28mm F1.4 lens is a great option for photographers who want a compact and affordable manual focus lens with a wide maximum aperture. While it may take some practice to get used to manual focus, the wide aperture and good image quality make it a worthwhile investment for many photographers.
