Midson was the 2011–12 League Two joint top scorer, along with Izale McLeod, Lewis Grabban and Adebayo Akinfenwa, with 18 goals and scored 20 goals in all competitions during the 2011–12 season for AFC Wimbledon, finishing the season as their top scorer. He was AFC Wimbledon's top scorer the following season as well, scoring 15 goals in all competitions and 13 in the league.
On 5 November 2010, he joined Southend United on a brief loan.[5] Following his return to Oxford, Midson scored his first career hat-trick against Torquay United on 3 January 2011.[6] Midson joined Barnet on loan in March 2011,[7] making his debut by coming off the bench in a 1–0 defeat at Aldershot Town.[8]
AFC Wimbledon
In June 2011, Midson signed for AFC Wimbledon. On 9 July 2011, he made his debut in a 2–0 pre-season friendly win against a Fulham XI.[9] He scored his first goals for AFC Wimbledon three days later, a brace in a 5–1 away friendly victory against Staines Town.[10] He made his competitive debut in AFC Wimbledon's Football League debut, a 3–2 home defeat to Bristol Rovers.[11] He finished the 2011–12 season as AFC Wimbledon's top scorer with 20 goals in all competitions. He also finished the season as joint-top scorer in League Two with 18 league goals in total.[12] In June 2012, AFC Wimbledon rejected a six-figure bid for Midson from Rotherham United, and he signed an improved contract with The Dons later that month.[13] On 2 December 2012, Midson scored for AFC Wimbledon in their first ever meeting with Milton Keynes Dons. AFC Wimbledon went on to lose the match 2–1 however.[14] After a rather inconsistent goal scoring start to the 2012–13 League Two season, Midson hit consistent goal scoring form towards the end of the season to help lift AFC Wimbledon away from the League Two relegation zone.[15] He passed the double figure mark for a second consecutive season after scoring the only goal with a superb chip in a vital relegation 6 pointer against Aldershot Town on 16 March 2013.[16] He then scored the winner in a 2–1 victory over Fleetwood Town which meant that AFC Wimbledon avoided relegation on the last day of the season. Midson finished his second season with AFC Wimbledon once again as the club's top scorer, having scored 15 goals in all competitions and 13 in the league to help The Dons avoid relegation from the football league and secure a third successive season in League Two.
