Access P-MC 70-210mm f/3.5 (one ring)
This camera glass has a variable aperture of f/3.5, which is relatively fast for a lens of this focal length. It has a single ring for zooming and focusing, which can be a bit difficult to use compared to lenses with separate rings for each function. The glass elements are coated to reduce flare and ghosting, which can be a problem with lenses that have a lot of glass elements.
The build quality is decent, but not exceptional. It was manufactured in the past, so it may not be as readily available as newer lenses. The resolution is good, but not as sharp as some of the more modern alternatives.
The bokeh, or the quality of the out-of-focus areas in a photo, is generally pleasing. It has a manual focus, which means that the photographer has to manually adjust the focus, so it may not be as convenient as autofocus lenses for some photographers.
Overall, the Access P-MC 70-210mm f/3.5 (one ring) lens is a decent option for photographers who are looking for an affordable ultra telephoto zoom lens with good optics and a fast aperture. However, there are newer alternatives available that may offer better performance and convenience.
Great choice mainly for good light conditions
62 mm lens filter diameter, rarely used filter size, make a try with step-up rings.
