When attached to a lens having a focal length of F, a 1.4Ã TC results in an effective focal length of 1.4ÃF, whereas a 2Ã TC results in an effective focal length of 2ÃF. Thus, a 400mm lens with a 1.4Ã teleconverter attached provides the same magnification as a 560mm lens, since 1.4 Ã 400 = 560. Similarly, a 400mm lens with a 2Ã converter produces the same magnification as a true 800mm lens. For birders, teleconverters can be a godsend.

Answer by Raven5591. Confidence votes 29. There is no agency that is proven to be the best state police department in the United States. Although state law enforcement agencies like to self proclaim themselves as the best ones in the nation, no-one can really say -- for now anyways -- which agency is better.owever, some agencies are clearly more prestigious than others based on staffing and the technology they use. The largest state police force in the United States is the California Highway Patrol as of 2008, according to FBI data.
