I’ve had an RX100 since December and I love it! Stellar low-light performance and all around really good image quality. Great auto as well as full creative control when you want it. The only I find myself missing (sometimes) is an EVF and a little more zoom.
If a small upgrade is worth it for you, only you can decide but as far as the camera goes it’s an excellent choice.
Wouldn’t handheld NIR instruments be more useful?
That way you get a profile from the actual contents, not just the packaging.
Don’t get me wrong – any measure to fight counterfeit drugs is good.
