I just got done shooting some circuit boards using my Tamron 90mm macro lens and three macro tubes.
The results are nice, but this is pretty much the limit of magnification I can get to with this setup. My field of view is something like half an inch square.
Is there a lens that will provide more magnification without being crazy expensive?

I am not shooting RAW for two reasons...my computer (2009 Mac) just takes for ever to process the files (so plea is into Santa) and my Lightroom 6 can't process the new A7III arg files. I may eventually just bite the bullet and become an Adobe subscriber, but for now am content with JPEG as it meets my amateurish purposes. I do, when appropriate, shoot RAW plus JPEG and use the JPEGS to identify which RAW image I may process.
As to the cause of the lines, they are not present on my original image when viewed full size on my computer.
