LensTip.com does extensive lens testing. This is from their distortion testing of the Nikon Nikkor AF-S 24-70 mm f/2.8E ED VR, 60mm micro, and 105mm micro lenses. With a zoom lens, you would need to do corrections to make the paintings straight.
Good news is that the camera can do that for you - in camera - as it does have all the correction tables for distortion - this goes for JPEG outputs - Raw you have to do outside the camera. Most PC photoapps do have correction tables so it is not a big deal at all - just make sure the app has correction tables for the lenses you use. And BTW - it is really mostly noticeable when you take pictures of brick walls.........................
