At f/8, the corners are finally haze-free and center sharpness reaches good levels. The haze is nearly gone at f/5.6 with strongly improved contrast and medium sharpness in the center. At 70 mm, the lens shows a small amount of barrel distortion (-0.4%).Īt 135 mm, the lens is soft and very hazy at f/3.5. The effective T-stop at f/3.5 is approximately T4.1 (-0.4 EV) for all focal lengths, which is good for a zoom. Vignetting is about 1/3 of a stop at f/3.5 and disappears from f/5.6 onwards. Starting at f/5.6, small red/cyan CAs appear which sharpen up at f/5.6 and are nearly gone by f/8. Diffraction starts showing at f/16 and softens up the image at f/22.Ī very light red and dark cyan glow is visible at f/3.5. At f/11, the corners further improve, but the central region is unaffected. At f/8, the corners finally start to sharpen up and center sharpness reaches good levels. The haze is gone at f/5.6 with sharpness and contrast improving strongly. Very slight scratches in the finishing, otherwise excellent condition.Īt 70 mm, the lens is hazy and soft at f/3.5 with very soft corners. The aperture is clean and fast.Įxterior: Very good. Uniform focus with low resistance, zooming is a little rough.
I don’t know how it got in there, but it’s stuck to the third element from the front.

On the plus side, the massive weight slightly reduces camera shake when shooting hand-held and 107 – 320 mm equivalent is a useful range of tele focal lengths. The mount on the NEX actually feels strained due to the weight, but I never had any mechanical problems. Handling on a NEX-5T is… well… heavy. As zooming and focusing is done with the same ring (“one touch”) and you tend to support the camera by it while doing so, locking focus is a little fiddly. The focus is smooth and has very little resistance, the zoom is a little rough and requires a medium breakaway force. The lens is massive, weighing in at nearly 0.9 kg. If you want to know more about the different revisions, visit Mark Roberts’ site. The third version by Komine (serial 28xxxxxx) shows a characteristic red stripe around the name ring and the second version by Tokina (serial 37xxxxxx) has neither of those features. This is the first version, produced by Kiron (Kino Precision) including a dedicated macro function with magnification ratio 1:2.2. You can easily identify this lens as the Kiron version by the two little wings near the mount and the serial, which starts with 22. There are at least five known versions from different manufacturers all sold under the Vivitar brand. The Vivitar (Kiron) Series 1 70-210 mm f/3.5 is an often entitled “legendary” third party zoom produced for different mounts.
