I recently picked up a Quantaray 70-300mm 1:4-5.6 LDO macro EF lens for my Canon 350D body. I am new to SLR's. I have been searching this site all day (like 12 hours) and can't find any info on this brand. does that mean that it is bad or just unused? I do wildlife mostly. I like the photos I have gotten from it. but thay are mainly point and shoot, except I like to manual focus. Is it something I should plan on keeping or look to sell and get something different? Thank you all. It has been fun seeing all of your photos and reading your posts.
