You want a mirrorless camera that lasts for years, not a gadget that feels outdated in six months. Buying the right body and lens now means you can skip the upgrade cycle and focus on your photos.
Watch the major camera brands for new model announcements. When the latest version hits the shelves, last year's model usually drops in price. That is your window to get a professional-grade camera for much less.
Remember that the 0% intro APR is a deadline, not free money. If you have any balance left after 15 months, you will start paying interest on what you still owe.
