Sun — budget manual-focus 80-200mm f/4.5 telephoto zoom sold across multiple 1970s-80s SLR mounts
Sun also marketed an 80-200mm f/4.5 telephoto zoom during the 1970s and 1980s, part of the same budget catalogue-lens category as contemporaries like Ozeck, Panagor and Sirius, sold to fit the major manual-focus SLR mounts of the period.
The lens uses a manual zoom and focus arrangement, typically a two-ring or push-pull design, with an automatic diaphragm and a constant f/4.5 maximum aperture across the zoom range. Exact element count, filter thread, weight and minimum focus distance are not confirmed from a verifiable source and are omitted.
Image quality is consistent with budget zooms of its era: acceptable centre sharpness through the middle of the range, softer results and lower contrast toward 200mm and wide open, with warmer colour typical of period lens coatings.
These zooms are inexpensive secondhand purchases, often bought out of curiosity or for cheap mirrorless adaptation. Buyers should check the zoom and focus action for smoothness, confirm the mount fitted matches their camera, and examine the elements for haze or fungus.
