In summer 1944, 5.(F)/123 was on the invasion front, and operated mainly Bf 109s. Strength on 9 June 1944 was 8 (5) Bf 109 and 3 (1) Fw 190; as the summer went on it became an all-Bf 109 Staffel.

I think a better candidate is 2./NAG 13 at Cuers-Pierrefeu. The aircraft have the small fairing protecting the reconnaissance camera opening in the lower fuselage and they have what I take to be red tactical numbers (5.(F)/123 used black). Also the additional camouflage under the engine is consistent with overwater operations (you can see the same on torpedo Ju 88s) which was 2./NAG 13's main role. There are several other photos of these aircraft in books that show the surrounding landscape. If you go to Cuers on Google Streetview, the distant hills look similar although there is no landmark I've noticed that would make the identification certain.
