The Rokinon 75-300 mm f/ 5.6 MC is a telephoto zoom lens with a fixed max. aperture for 35 mm SLR Minolta SR cameras.
The lens gets along perfectly well with cropped sensor cameras (e.g. Sony E (Nex) bayonet) considerably increasing the focal length (today's limit for Sony E kit lenses is 200-210mm), as well as expanding capabilities of controlling aperture. The lens is considerably superior to kit lenses and is a real alternative to the SEL-55210 when covering the subject in a focal plane. Unfortunately, the lens has neither image stabilizer nor autofocus (as well as a number of automatic control capabilities modern cameras have). As for its depth of field the lens is not different in sharpness and a rather moderate level of horizontal and chromatic aberrations from the SEL-55210, but is inferior (even when stopped down) concerning its depth of sharpness, i.e. it is capable of covering a definite plane as well as does the SEL-55210, but it can't cover the whole space in the hyperfocal plane.
The lens is rather heavy, but handy and easy to use. It functions perfectly well at low temperature. If it were possible to predict what will be of interest at a long focal length (a non-dynamic, still subject or landscape, or a fast moving subject), you could choose to take either the SEL-55210 or the Rokinon 75-300mm with a good aperture. Taken together these lenses are rather heavy, but with the appearance of the Rokinon 75-300mm I'd prefer to have this lens "on duty" in my bag. Though in some situations it makes me regret my choice and remember the SEL-55210. Yet its basic capabilities (focal length, lens speed) are preferable.
