Which 70-300mm lens has the best optics?
Lenses made by Nikon and Canon are known for having superior optics compared to other brands. Optics are important but there is more to making a lens functional than optics. if you are willing to sacrifice a little optical quality (usually unnoticeable to all but true professionals) you can either save lots of money or get additional features that make the lens a better tool. Hammer made by Dewalt – $20 hard metal head and plain handle. Hammer made by XYZ – $20 hard metal head and handle with rubber grip. which is the better tool? how much of that $20 goes to buy the name Dewalt? how much quality does XYZ lack in the metal or construction of a hammer compared to Dewalt? you can get comprehensive reviews of lenses and cameras at www.dpreview.
