Are Quantaray lenses good?

Ron, great explanation. I'm just a rookie in lenses

I have been shooting pictures for near 50 years and had great luck with the Quantaray lenses . They are made by Sigma and true thay are on the lower end of there cost factor . I have 3 different auto focus lenses from them [Quantaray] a 18 to 90mm A 70 to 300mm and a 1000mm and they all run very quit and smooth. I also have the same 3 lenses in the Sigma lenses and believe me when I say it's darn hard to tell them apart

Comparing 2 of the same thing (low cost lenses by the same maker) doesn't really help much.

Generally you get what you pay for (and a large constant aperture greatly adds to that cost). The budget lenses work and may be fine for now, but you will likely want to upgrade a level or two in the future.

Canon has a decent 55-250mm ( I think that's it) and that would be my starter for a budget tele-zoom.
