Vivitar Series 1 70-210 f/3.5 Macro from Kiron (v1).Other than that, the lens is superb in clarity, color, contrast and sharpness for a zoom. I may need to buy a lens hood in size of 62mm to test close up again. I highly recommend with the caveat noted in close focusing where I find ghosting and clipping of highlights on flower edges. Overall the lens is sharp, colorful and contrasty.The only caveat lie in the closeup as I do find the close up to be weaker than the Kiron version. Sharpness is very close to Kiron and Komine versions, the Tokina when stopped down to f/5.6 or smaller, seem to be the best in sharpness.Manual focusing is excellent with this lens. I like the focusing and zooming in Tokina better than Kiron. The zoom actually works better than Kiron as I recall. Though a one-touch zoom design similar to Kiron and the Komine versions, the lens does't have the issue in front heavy with tendency with zoom ring falling to the front.I am not sure if it is ghosting or the need for a lens hood. Not only is the close up ratio is weaker in 1:4 as compared to 1:2.2, the lens in wide open aperture has some flare on edges of flowers. When I test the Tokina version of Vivitar Series 1, I find the Kiron version better.

Filter size is 62mm sharing the same dimension like the Tamron 70-300 Di LD.

I feel very comfortable to hold the zoom when compared to the Kiron version.

Comparing to heavy weight as in 879g for the v1:Kiron version or the 860g in the v3:Komine, I like the Tokina based on the weighting factor.

Constant f/3.5 throughout the range from 70-210mm is very fast as compared to my DA 50-200 f/4.0-5.6 or my other longer zoom in Tamron 70-300 Di LD Macro f/4.0-5.6 zooms.The Kiron version has better macro at 1:2.2 but this Tokina version has macro of 1:4. I had impressive experience with the v1 of the Vivitar Series 1 70-210 f/3.5 from Kiron as one of the first three versions recommended by Mark Roberts.
