Vivitar MC 70-210mm f/4.5 (Kobori)

The lens has a well-built construction with good quality glass elements and lens coating. It was manufactured some time ago, but still performs well. The aperture range is f/4.5 to f/32, providing decent control over depth of field. The lens can produce good bokeh, which is the quality of the out-of-focus areas in a photo. The lens is manual focus, which means you have to adjust the focus ring yourself, but this can provide more control over the focus. The resolution of the lens is decent, meaning that it can produce sharp images. Overall, the Vivitar MC 70-210mm f/4.5 (Kobori) is a good alternative for those looking for an affordable ultra telephoto zoom lens with good optics and build quality.

Great choice mainly for good light conditions Has 6 aperture blades, this number of blades are commonly used. Having rounded blades provides out of focus circle shape closer to a circle.
