Tokina Tokina 80-200mm f4.5 Heritage

เรื่องราวของเลนส์

The Tokina 80-200mm f/4.5 (RMC / SMZ845 line) is one of several 80-200mm telephoto zooms Tokina produced during the manual-focus era of the late 1970s and 1980s, offered across a range of mounts including Pentax K, M42 and Minolta MD. Reviews note it is the smaller, lighter and cheaper variant within a broader family of Tokina 80-200mm zooms, which also included a constant f/4 version, a constant f/2.8 professional AT-X version, and an f/3.5-4.5 macro version. A 1984 brochure documents the updated versions. Note that the f/4.5 designation is somewhat ambiguous in the community: one review database catalogs it as an f/4.5 (12 elements in 9 groups, 52mm filter, 460g), while a video-focused reviewer discussing the cheaper Tokina 80-200mm RMC refers to it as a constant f/4. These budget RMC zooms are prized largely for their extreme affordability, sometimes selling for under $20-$40. No established nicknames or community jargon are documented for this lens. Its modest cult following stems from being one of the cheapest ways to cover the 80-200mm range with a usable constant (or near-constant) aperture.

สรุป: The Tokina 80-200mm f/4.5 is a bargain-basement telephoto zoom for enthusiasts and video shooters who want to cover the 80-200mm range for almost nothing. It rewards patience with pleasant bokeh and a dreamy wide-open look, but it is soft, lower in contrast than its professional AT-X f/2.8 sibling, and genuinely difficult to focus - making it best for static subjects and casual use. Buy it as an affordable stopgap or a fun character lens, not as a performance instrument.

คาแรกเตอร์ของภาพ

โบเก้

โบเก้ที่น่าพอใจและใช้งานได้จริง ให้ความละมุนแบบที่เห็นในรุ่น f/2.8 เล็กน้อย โดยปราศจากลักษณะโบเก้แบบหมุนวนหรือเป็นฟอง

โทนสี

การถ่ายทอดสีอ่อนกว่า รุ่น f/2.8 ที่มีราคาสูงกว่า แต่ยังใช้งานได้ — โทนสีเฉพาะยังไม่เป็นที่ทราบแน่ชัด

ความคม (เปิดสุด)

เมื่อเปิดรูรับแสงกว้างสุดให้ภาพนุ่มนวลและมีบรรยากาศฝันๆ — เมื่อหรี่รูรับแสงภาพจะดีขึ้นแต่ก็ยังไม่เทียบเท่ารุ่น f/2.8 ได้ แม้ที่ f/8

คอนทราสต์

ความเปรียบต่างต่ำกว่า AT‑X f/2.8 โดยเฉพาะเมื่อเปิดรูรับแสงกว้างสุด

รีวิวจากผู้ใช้

ข้อดี

Exceptional value - one of the cheapest ways to get an 80-200mm zoom, sometimes under $20-$40
Pleasant, usable bokeh that even approaches the dreamy look of the more expensive f/2.8 version wide open
Covers a versatile telephoto zoom range at a constant (or near-constant) aperture
Solid all-metal construction on the RMC-family zooms
A great stopgap lens for someone who needs to cover these focal lengths before upgrading to better glass

ข้อเสีย

Difficult to focus manually, leading to many out-of-focus shots on digital bodies
Frustrating green-button metering workflow on Pentax DSLRs
Soft and low in contrast wide open; can't match the f/2.8 version's sharpness even at f/8
Best suited to non-moving subjects due to focusing challenges

เทคนิคการใช้

Stop down a stop or two from wide open to improve sharpness and contrast
Use it for static or slow subjects; the manual focus makes moving subjects difficult, especially on digital
Lean into the dreamy wide-open look intentionally for softer, flattering images rather than expecting clinical sharpness
For video, the softness and lower contrast are far more forgiving than in stills
On Pentax DSLRs, be prepared for green-button stop-down metering
