Hi, does anyone have the manufacturer instructions for the Promaster AF Spectrum 7 3.5-4.5 28-70 IA Zoom ( Power Zoom)? I understand that it may be a rebrand of a Tamron lens. It 's the only lens that came with a used minolta maxxum 2xi. I sent a contact email to Promaster on their site asking the same ?. Thought I would try here as well.

I'm also interested if anyone has used this lens. I understand that they were made to fit many models ...Pentax, Canon etc. If you did use the lens, what is your overall impression. What type of shots did you use the lens for. Can you share some of your keepers?

Thanks for reading,
