Tamron Tamron 28mm f2.8 Heritage

เรื่องราวของเลนส์

The reviews provided describe a Tamron Adaptall-2 28mm f/2.5, not a 28mm f/2.8, though both belong to Tamron's broader 28mm lineup and share the same interchangeable Adaptall-2 mount philosophy. The defining historical innovation Tamron championed with these lenses was the Adaptall-2 mount system: rather than committing a lens to a single camera mount, Tamron engineered a swappable mount interface. As the reviewer notes, this was effectively a precursor to the modern adapter-ring culture we now use to adapt vintage glass, except Adaptall let you replace the entire mount for a far more solid connection. A single Adaptall lens could be fitted to OM, MD, M42, PK and even native mirrorless mounts (MFT, Sony-E, Canon EF, Samsung NX), and the reviewer highlights it as the only lens (mount system) usable on both Canon FD and Canon EF cameras. This versatility is precisely why the reviewer kept reaching for it. No established nickname is evidenced in the reviews. The lens has a following among budget-conscious vintage video shooters because 28mm lenses were among the most affordable vintage optics ever made, and this Tamron feels solid and well-built for the money.

สรุป: A solidly built, affordable vintage wide angle whose real appeal lies in the extraordinarily flexible Adaptall-2 mount system that lets it live on almost any camera. It is not a sharpness champion, particularly at the edges on full frame, but it is thoroughly usable and well-suited to video shooters and Super35/APS-C users who value smooth non-extending focus, non-rotating filters, and cross-system versatility over clinical corner performance. Note: the source reviews describe the f/2.5 Adaptall-2 version rather than a specific f/2.8 M42 model.

ความคม (เปิดสุด)

ไม่คมที่สุดเมื่อเปิดรูรับแสงกว้างสุด แต่ยังถือว่าใช้งานได้ — จะมีความนุ่มบริเวณขอบและมุมภาพโดยเฉพาะบนเซ็นเซอร์ฟูลเฟรม ขณะที่บน APS‑C หรือ Super35 ปัญหานี้จะน้อยลง

ข้อดี

The Adaptall-2 swappable mount system, described as the most versatile and flexible mount system the reviewer knows of, allowing use across OM, MD, M42, PK and native mirrorless/EF/FD mounts
Solid, high-quality build that feels nicer than some modern lenses costing many times more
Very smooth focusing ring with 140° of rotation and hard stops at each end
Focusing ring does not extend when focusing, which is great for follow-focus use
Front element does not rotate, so filter effects are not disturbed when focusing
49mm filter thread that works with cheap filters (or step-up rings)
Affordability typical of vintage 28mm lenses
Usable image quality even wide open

ข้อเสีย

Not the sharpest lens wide open
Edge softness, especially noticeable on full frame
Polarizing optical character that some people simply dislike
The front does extend slightly when focusing (minor, but noted)

เทคนิคการใช้

Take advantage of the Adaptall-2 system by buying the specific mount for your camera rather than stacking generic adapter rings, for a more solid connection
Use a focal reducer (e.g. an FD Lens Turbo II via the appropriate mount) on smaller sensors to recover field of view and speed
Shoot on APS-C/Super35 where edge softness is far less of an issue than on full frame
Don't be afraid to use it wide open; the reviewer considers it usable at f/2.5
Because the front element doesn't rotate, it pairs well with polarizers and graduated filters
