I tested out the macro feature built in to the Leica Q, and it works quite well for the purpose of photographing other gadgets. I don't normally do much macro so I can't speak to the "pro" requirements but it worked fine for me.
The Q camera I used for these images is from Leica Store Miami.
* Images were adjusted in Lightroom. These are customized, not the colors you would get straight from the camera. The Leica Q has a very accurate color rendering. These are much more blue but I like it to emphasize the silver of the iPhone.
More sample images coming soon...
Thanks to Leica Store Miami for loaning me the Leica Q
