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.

If you want a pistol on the other hand there are also plenty of .22's out there, but a really good one is the Ruger mark III, highly accurate, cheapish for a good .22lr and more accurate than 95% of the guns out there.#4 gendoikari87, Jan 16, 2011.hogger129 Well-Known Member.irst off, if you are just target shooting, anything chambered for .22LR is going to be the most affordable to shoot. You can get kits for some handguns too that will rechamber them for .22LR. As stated by gendoikari87, Ruger makes a .22LR pistol that is very good. After that, these are my suggestions.
