Get closer to the action. Whatever your lens, this will get you twice as close. This makes a great inexpensive accessory for better candid photos, wildlife photos, or any time you need to get closer but can't. You maintain the same minimum focus distance so you also gain some close-up capability. As with any 2X teleconverter you will lose 2 stops of light gathering power. Fits any MD & MC mount Minolta camera bodies (such as the SRT series, the X, XG, XD series). Will not fit on the newer auto focus cameras from Minolta, Konica Minolta, or Sony!
