Your main issue is likely lighting consistency, not the camera.

From the answers provided, the photo box appears to have opaque sides, which limits you to lighting from the front. That creates flat, flash-like light and can make products look dull. A better approach is softer, more controlled light from the sides. If the box can’t diffuse light, don’t rely on it—use a simple DIY light tent instead, such as a box with the sides cut out and covered with translucent paper so the lights shine through the sides.

Also, set and control white balance manually. If you leave white balance to auto, color can shift from shot to shot, which hurts consistency and makes products look less true-to-life. Create a custom white balance for your setup and keep it the same while shooting.

In short:

• Use softer, diffused side lighting rather than direct front lighting
• Reposition lights instead of aiming everything straight at the product
• Set a custom white balance and keep it fixed
• Keep your shooting setup unchanged between products

Those changes should improve consistency far more than changing focus method or relying on editing corrections later.
