Tele-Lentar Tele-Lentar 200mm f4.5 Heritage

Overview

The Tele-Lentar 200mm f/4.5 preset is a lens sold under the 'Tele-Lentar' branding, distributed by Lenco Photo Products. According to camera-wiki, the T-mount version bears a 'Lens Made in Japan' mark, but the actual manufacturer of the lens is unknown. Tele-Lentar was a rebrand/house-brand line, and various Tele-Lentar telephotos (including 200mm and 300mm variants) circulated among enthusiasts as inexpensive Japanese-made preset tele lenses. The reviews here provide little detail specific to this f/4.5 model beyond its distributor and 13-blade iris; most enthusiast discussion is scattered across forums like mflenses and Reddit's VintageLenses community, where users treat these as budget-friendly vintage telephotos. No established nickname or jargon is evidenced for this particular lens. Its appeal, where it exists, stems from being an affordable, all-metal preset telephoto with a high blade count for its class.

Verdict: The Tele-Lentar 200mm f/4.5 preset is a budget vintage Japanese telephoto of unknown manufacture, most notable for its 13-blade iris. It suits collectors and experimenters who want an affordable preset tele with smooth aperture geometry, but documented optical detail is thin. Buyers seeking well-characterized rendering should look elsewhere; those who enjoy exploring obscure rebranded lenses may find it rewarding.

Optical Character

Community Insights

What people love

The high 13-blade iris, which promises smooth, rounded aperture-based highlights uncommon in budget telephotos
Its status as an inexpensive, Japanese-made preset telephoto suitable for portraits and telephoto work

What people dislike

The manufacturer is unknown, making documentation and support scarce
Preset aperture operation is less convenient than automatic diaphragms (general trait of the class)

Pro Tips

Confirm the mount before purchase; the documented f/4.5 version is a T-mount lens, so an appropriate T-mount-to-M42 adapter is needed for M42 use
Use the preset ring to set aperture, then focus wide open and stop down for the shot
A tripod or monopod aids stability with a 200mm telephoto
