Second, even if it does say that, there is no reason to believe it. įirst, I do not see where it says that the Vivitar lens was designed by Minolta. if the info on this site is accurate, then it was designed by Minolta. Why should this be a Minolta design, if it's simply a rebranded Sigma lens !? Definitely no need for a separate lens db entry If the optics are anything like as good as the AF 100/3.5 MC Macro, then it ought to be something that would be in ultra high demand, but there's not much out there in order to get technical, image and user details. Whilst this thread may be a few years old now, I've checked as much as I can, and if the info on this site is accurate, then it was designed by Minolta, thus the question now is how can the lens be a rebrand of the old Sigma 'Zen' if it was made by Minolta? Surely it should be in the Dyxum lens database as a standalone lens, but it's not listed and I have submitted lens data but there's nothing showing. There is also a 'Vivitar Series 1' 28-70mm 2.8 which is the same as the Sigma Zen (I've owned both, both were disappointing). I think I'd pay about $120 for that Sigma/Vivitar 70-210 but more than that and I'd rather just save for the Tamron you mentioned for example. Perhaps good enough for a fast long lens for a lower pixel density camera. Acetone will also strip off the labeling, but sometimes it's the only option and it of course adds a bit of mystery when people see you shooting with a completely unlabeled lens.Īccording to the lens database it scores adequately. There is also a 'Vivitar Series 1' 28-70mm 2.8 which is the same as the Sigma Zen(I've owned both, both were disappointing).įWIW, that nasty 'Zen' coating on the old Sigma lenses can be removed with rubbing alcohol if you're willing to work at it, and acetone if you're not.

Maybe try to find a Tamron 70-200/2.8 instead? It will cost a bit more but probably a much better lens. Not a particularly good lens, and to add insult to injury the coating on these lenses tends to get sticky over time which is a pain. Yeah, as has been mentioned this is a rebrand of the old Sigma 'Zen' 70-210/2.8.
