This week Canon announced its new 50mm f/1.8 STM, a followup to the popular and cheap “Nifty Fifty” 50mm f/1.8 II. Aside from a better build quality and a metal mount, the new lens also features Stepping Motor (STM) technology for
smooth and silent autofocusing.
If you’d like to see how the focusing sound and smoothness compares between the new lens and its predecessor, check out the comparison video above.
The 1.5-minute clip was published today by Latvian gadget site CTRL.lv, which was invited to a Canon event to play with pre-production copies of the new 50mm f/1.8 STM.
“The biggest difference is in the focusing motor, and it really is much smoother and quieter, like STM should be,” the site writes. “It doesn’t sound like a broken printer anymore, so it’s much better for videos now.”

Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
