This is for the Vivitar "Series 1" 70-210 F3.5 constant aperture. To make it short - while nothing stellar, this is a really solid performer, especially minding the price. I have used this lens on an apsc crop-sensor canon dslr with great satisfaction. Picture quality is ok on F3.5 for most situations, gets much better at F5.6. The telefoto end is softer than the wide and mid ranges. CAS is relatively low. I have used this lens for videography where constant aperture is important and the lens doesn't really have to be super sharp. The only drawback I can think of is the weight. It's a bit heavy, but nothing terrible. But for a lens this at this price - whatever. If you are on a budget and need telefoto zoom with constant aperture this is the perfect lens for you.
I spent a few weeks researching a vintage zoom lens within this range 70-210mm which equates to a reach of over 100mm to 300mm on my APSC camera. After looking at this Vivitar, I then researched the multiple iterations of this lens and was surprised to find the Komine version 3, was the highest rated. This lens was well maintained, I found nothing wrong. I took it out and was quite pleased with the results. As it is manual only, I recommend stabilizing it when shooting.

I've enjoyed using this lens for my micro four thirds system. Very sharp and constant f3.5 is great for telephoto. I would recommend this lens to anyone in the same boat. Just make sure you know the serial number and check to make sure it was made by a good manufacturer. This website will help: http://www.robertstech.com/vivitar.htm
TO ME, EXCELLENT MANUAL LENS... A BARGAIN!
