Until now, number of rumors have been tossed up regarding the replacement of 25 years old Canon EF 50mm f/1.4, but in the end all the expectations were trashed, unexpectedly. But this time, we are very much sure that Canon is under the serious development to bring an EF 50mm f/1.4 nano USM lens within this year, which is said to be the next version of current Canon EF 50mm f/1.4.
By the way, the upcoming lens won’t feature I.S and will use the nano USM motor. Moreover, according to the rumor mill Canon may choose Q4 of 2017 as the best time to announce this most anticipated 50mm nano lens and therefore shipping will be in 2018.
It was the only information we have collected so far and if we get any other we must pass it on.
