Reuters doesn't know the difference between mirrors and lenses

Telescopes are getting bigger.  Back in the day (1940's), the 200 inch Mt Palomar telescope was the absolute last word.  Today, under construction in Chile, is the Giant Magellan Telescope,  (GMT) with 327 inch mirrors, seven of them ganged together, yielding a combined aperture of 981 inches.   That's really really big. 
   Funny, the Reuters people, in this article , describe the GMT as using lenses.  That's not right.  Big telescopes have used mirrors for better than the last 100 years.  Reason, chromatic aberration.  Mirrors reflect light of all colors the same way.  Lenses don't, red light bends differently than blue light, causing color fringes in the image.  The extreme case is the rainbow of colors you get when sunlight shines thru a glass prism.  Just to double check, I googled up the GMT website, and as I knew, GMT uses mirrors. 
  Translation, the Reuters people don't know the difference between mirrors and lenses, and are ignorant of the development of telescope art over the centuries.  This is fairly typical of newsies,  a profound ignorance of everything technical.
