A:AnswerIf you only want to pay a little at a time you have to either use a credit card or some other finance option. I don’t think they will trust you to come back and give them cash.
A:AnswerYes. Ensure that you’re shutter speed is below 1/500, maybe more, like 1/1000. Though you may want to get a telephoto lens for what you’re wanting to take photos with.
