Tamron SP Adaptall-2 70-210mm F/3.5 Model 19AH
Tamron 19AH lens is better in performance than the Vivitar Series 1 Comparison . And I tested a used copy of this legendary lens on the adaptall world this weekend. It is quite a good zoom. Though the weight is about the same as the Komine copy v3 in Vivitar Series 1, the length is longer making it harder to handle. The battery grip does help a bit in the balance.
I used to rely on my Vivitar Series 1 70-210mm f/2.8-4.0 Komine as my go-to zoom in that range, now I am not sure as I find great competition between the two. Close up in 1:2.6 in 210mm end is not as good and easy when I tried it first time as the Vivitar, but the portraits and candid street shots give good color and offer quite a lot of details for a zoom. Though it is a one-touch zoom design, it offer less zoom creep than the Vivitar. Focusing ring is top notch for manual focusing in both the Tamron and the Vivitar, and I can't tell which one is better. As for handling, the Vivitar is easier as it is shorter and less bulky. The Tamron is about similar weight and about 1.5 inches longer. It has a unique design in the zoom ring that doubles up as a lens hood. Will document more with product shots next.
Impressions & Notes
- I favor this zoom over any of the first three versions of Vivitar Series 1 zoom
- It is harder to handle this lens due to its size
- Zoom extends from 70mm to 210mm whereas the Vivitar zoom goes in reverse going from 210mm to 70mm
- 1:2.6 close up is at 210mm. It is harder to do close up as compared to Vivitar Series 1 zoom as the lens extend to the far end.
- Sharpness is great on this zoom. Many test shots in f/4.0 have good sharpness
- Both contrast and color are extraordinary when compared to my experience with Vivitar Series 1 zoom
- PF/CA is found moderate. I was expecting to find much less CA/PF in this zoom but pixel peeping reveal the presence and hinting of moderate amount PF. My impressions on PF on this zoom is better than Vivitar Series 1 70-210mm f/2.8-4.0 from Komine.
- Continuous Focusing CF is a feature in this zoom where by turning focusing ring to minimum focusing distance, the zoom will move towards the 210mm zoom positive to achieve 1:2.6 ratio.
- When extended to 210mm, the zoom seems like 2 inch longer than the Vivitar Series 1 from Komine
- Unlike Vivitar Series 1, there is no zoom creep. The focusing ring is top-notch for manual focusing, the best in a zoom that I have used -- long throw, precise, quick zooming and focusing, and no zoom creep
