A good mirrorless camera should last you five to seven years. It is about getting a sensor that handles low light and portraits better than any phone. We want to find a body and a kit lens that lets you grow without needing to upgrade in twelve months. Buying once saves you more than any discount.
The trick is watching the release cycles. When a brand announces their latest flagship, last year's model usually sees a price cut. You get most of the tech for a much lower price. Since a $750 setup is a big hit at once, we can break it down into smaller monthly chunks.
The 0% interest period is a hard deadline, not a permanent discount. If you still have a balance after those 18 months, the standard variable APR kicks in on whatever is left. It is a stay of execution on interest, so keep your monthly payments on schedule.
