Well, this is a surprise. It seems that the second-hand market is following suit with new purchases. According to used gear retailer KEH, who reported on their blog, mirrorless sales have overtaken DSLRs in the used market for December 2020. This is the first time that this has happened in the company’s history and they say the trend looks to continue for 2021.
KEH notes that DSLRs has been a huge part of their business and that they ruled their top 10 best selling cameras from 2010 to 2019. In 2020, that changed, when three mirrorless bodies entered that top 10 list with the charge being led by the Sony A6000.
