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.

35. The 10mm and 45 are better than the 40. The 40 is a step up from the 9mm and is pretty standard in le now because we hire wimps. Seriously, alot of rookies have a hard time with the 40 and a better caliber would force them out of the academy....so we cater to the need for officers over the need for better weapons..lock 40's are Glocks in 40 caliber. Glock model 20 is a 10mm Glock 21 is 45 cal. Here, take a look at what a REAL water pistol is! http://www.glock.com/pistols.htm ------------------ Trust me. I'm from the government, I'm here to help..
