Vivitar was
a lens re-seller, and the serial numbers are an indicator who actually
manufactured the lens. There is some difference in optical quality and exterior
per manufacturer. You can check who made your lens on this list
The serial
number on my lens starts with 28 which means it’s made by Komine.
I am not
sure if I am really positive about this lens. In test shots it shows what it
can do, but in the field (which is way more important) it is a lens which takes
getting used to before you get good results. It is pretty difficult to get the
right focus, and if you missed just a bit you will notice it. I guess I will be
more positive about it in the future, but for now I really need to pay
attention to my focus, more than on any other lens (except for macro photos)
Handling the lens
The lens feels solid, it is quite heavy but
not front heavy. You can stabilize it quite easily and does not feel unbalanced
on my D60. The focus ring is quite smooth, not as smooth as my Nikkor lenses,
this one uses oil. This is a major disadvantage during cold days because the
oil becomes stiff and the lens is harder to focus. However most of the
off-brand lenses use oil in their focus mechanisms so I won’t nag about it
anymore. The thing is, focus is really critical with this lens. When I first
got it and tested it I was a bit carless about my focussing. At first I thought
I bought a dog because images were soft. This lens does not tolerate focus
errors at all, and the right focus is a bit hard to achieve. It takes a smaller
twist on the focus ring than I used to to defocus the lens. This is could be
because the focus ring is not precise enough, but I think it’s mostly because
it is a longer lens with a faster aperture than I normally use. The lens has a built
in hood. It is relatively short and I am not sure how effective it really is.
But it probably is better than nothing and it seems like a nice feature. (especially
during the rain to keep your front element dry)
Results
Wide open this lens is extremely prone to
CA. In high contrast situations you’re able to see it without looking closely.
During processing you will find CA everywhere. However it falls within the
limits of what’s correctable in my post processing program ( I use Capture NX
2, but I’m sure any other program will be able to cope with it as well)
The sharpness wide open is a small OK. It
does not shine wide open. At f/3.5 details start to blur, perhaps also caused
by the CA.

At f/5.6 the quality starts to increase
rapidly. Sharpness increases to great, but CA is still visible, but a lot less.
You won’t be able to see it at normal magnifications, only when you zoom in for
small precise adjustments (hey not pixel peeping right?) I would be confident
to use this lens for a large print for a paid job at f/5.6.

Bokeh is all right, with busy backgrounds
it can be distracting, especially branches. The only solution is to open up
your lens, or come closer. But a lot of lenses won’t be able to handle it very
well. If the background is a bit smoother the bokeh will be all right.
Conclusions
I bought this lens mostly because I wanted
something faster than my 70-210 f/4-5.6 for my walk around wildlife
photographs. And this lens does the job all right, it is a good lens but
nothing special. It is not as sharp wide open as my 70-210, but this one has a
faster aperture. I end up using this lens as a regular 200mm f/5.6 lens with
some emergency extra F-stops. The reason I do so is because focus is really
critical and I just need the DoF to get sharp images. Especially for wild life
because the focus ring has more friction than my Nikkor lenses (but as much
friction as my other 3rd party lenses) which makes it a bit less precise.
And because the real sharpness of the lens is just better at f/5.6 So in
conclusion I do recommend this lens, but don’t pay too much for it. The lens is
OK, but nothing more.

Mooie foto's van de awd

Fijne lens is dit, nog steeds. Ik gebruik hem met een adapter op een Nikon 3100. Met tussenringen en CA correctie in Adobe LR echt een toppertje
