Re: Opinion on Vivitar Auto 28mm F2.5 please.

Not sure what you mean by the last comment. Tokina is the only 3rd party lens maker to get a lens into Photodo top 10 of all time MTF50 rating. Neither Sigma or Tamron managed to do that. Tokina has made a lot of lenses for others (like Kiron). Tokina has built most of the big pro tele lenses for Nikon for decades. But Tokina is primarliy a glass foundry. Their lens business is about as big in comparison as Sigma's camera business is to Sigma's lens business. Unfortunately for us Tokina has a production rule that they will not build a lens in a mount that will not sell a million copies. So we can't get a Tokina AT-X 11-16/2.8, among others.
