Wow! I had an SRT-101 also about 50 years ago. Before that at Topcon which I lost. A shame, that was a great film camera. Weighed a ton but took great photos.

I'm new here folks so bear with me. I recently stepped up to a Canon 80D from my old 40D. But I kept my old 28-135 lens. The old lens is fine but just wondering if it is worth it to get the newer 18-135. Am I losing a lot staying with the old lens, besides the wider angle. Also the 18-135 comes with 2 different motors, USM and STM. I know the difference, but just wanted to know of any opinions on choice of motors. I take mostly stills, but do take some videos with the 80D.
Thanks
