The Canon EF 70 300mm lens has an image stabilizer, diffractive optics, and a 58 mm filter diameter. It has a minimum focusing distance of 1.5m with an object magnification of 1:4.
The Canon Ultrasonic 100-300mm lens features a zoom range of 100-300mm, ultrasonic autofocus motor for fast and quiet focusing, image stabilization, and a minimum focusing distance of 1.5m. It has a maximum aperture of f/4.5-5.6 and is compatible with Canon EF mount cameras.
The fork lateral dimension is adjustable and usually this range is between 300mm to 1200mm.
The magnification of a lens depends on the camera's sensor size and the distance to the subject. A 300mm lens on a full-frame camera can provide around 5x magnification, while on a crop sensor camera it can offer around 7.5x to 10x magnification.
The main difference between a 55-300mm lens and a 70-300mm lens is the range of focal lengths they offer. The 55-300mm lens has a slightly shorter focal length range, while the 70-300mm lens provides a longer reach. In terms of performance, the 70-300mm lens may offer better image quality and sharper results at the longer end of the focal length range compared to the 55-300mm lens.
The main differences between the Nikon 55-300mm and 70-300mm lenses are their focal length ranges and maximum apertures. The 55-300mm lens has a slightly shorter focal length range and a smaller maximum aperture compared to the 70-300mm lens. This means that the 70-300mm lens can zoom in closer and allow more light to enter, potentially resulting in better image quality in low light conditions.
The main difference between a 70-300mm lens and a 55-300mm lens is the focal length range. The 70-300mm lens has a slightly longer reach at the telephoto end compared to the 55-300mm lens. If you need more zoom capability for shooting distant subjects, the 70-300mm lens would be more suitable. However, if you don't need the extra reach and prefer a slightly wider angle at the lower end, the 55-300mm lens may be a better choice for your photography needs.
