For Nikon SLRs, if you don't use flashes too often, a CR2 battery should last quite a long while (or 10~15 rolls of film). Even though Canada is cold in winter, you don't want to let your camera sit outside overnight, do you? So on a cost/roll basis, I have found that CR2 is actually cheaper than No.5 size ones (those batteries aren't cheap neither in Canada, right?)! And the good thing about CR2 battery is that it never leaks! |
