belated post here. Congratulations on doing such a wonderful job with the equipment you have. These are very nice and it sounds like you've headed in the direction that "you" wanted. There are a lot of YouTube Videos of high end european product and jewelry and fashion photographers, Yuri, etc, that you can get equipment and lighting setup ideas, as well as inspirations on your compositions. Suggest really take time to get your "iconic keepers" over taking a large number of shots that are throwaways.
Wife and I have been commercial product and stock photographers ever since film. It is a demanding but rewarding genre of photography. Have fun with it. Up your gear as your skills improve as well. Though an investment, consider a full frame or aps-c sensor camera with proper lenses and lighting, and if you have the space, shoot "tethered" to a laptop or computer and use a very solid tripod and setup or lighting table. So you don't touch the camera. Also, learn to "focus stack" to control your depths, etc. The later and newer Olympus OM's do in camera focus stacking and finishing.
If you have the budget, shoot raw and refine your post processing. Have fun. k
