~ After reading a series of favorable customer reviews of the EF 40mm f/2.8 STM wide prime lens, Shorty Forty, I bought a copy and arranged to mail another copy to a photographer friend in China…there's a substantial scale differential between the EF 40mm f/2.8 STM and the EF 400mm f/2.8L IS II super telephoto lens…the two handheld test shots in my poorly lit room lived up to the len's reputation for high contrast, vivid hues and satisfactory focus
