The Sony a6400 is good for product photography. It offers 24 megapixels and excellent autofocus, so your product photos will have plenty of detail. And it's a great camera for video, making it possible to record high-quality videos for your Etsy listings. But the biggest asset is the range of lenses you can buy for this camera. Of course, a quality camera is essential, but quality lenses are perhaps more important, especially for product photography. There are plenty of Sony E mount lenses that will help you capture fantastic product photos, no matter what your products are.
