112 mm de diametro, que chulo ¿ no ?
Pues eso, el bueno de Ken Rockwell ha logrado enloquecerme. No me suena este objetivo que dice que ha probado, aunque al principio de su artículo pone esto, que da bastantes pistas.
Versions
- I have the AT-X AF version.
- There is an earlier manual-focus only version, which presumably has the same optics.
- There is a newer AT-X AF II version.
- The newest version is the AT-X PRO version, which I believe also has the same optics, but adds a push-pull clutch to the focus ring to speed-up auto/focus switching. This version speeds that up, but once in manual, I suspect the feel is better in the earlier versions.
Deduzco por tanto que no es una novedad novedosa, pues se trata de la primera versión AF.
Algunos datos sobre él: Tokina 300mm f/2.8 AF AT-X (Full-frame, 35mm and APS-C coverage, 112mm filters, 77.2 oz/2,190g, 8’/2.4 m close focus
A esto añado sus clásicos apartados de «lo bueno» y lo «no tan bueno»
Good
- Very sharp.
- Reasonably close focussing: 7.9’/2.4m.
- Fast manual focus; flicks with a fingertip.
- Solid all-metal construction.
- Simple, sturdy technology suggests long service life — there’s nothing to break!
Bad
- As with all third-party lenses, there’s always the potential for incompatibility with some models of camera or lens adapters.
- No instant manual focus override; have to move a switch.
