The list of tagets on this site:
https://saturn.jpl.nasa.gov/galleries/raw-images/does not include Aegir, so it looks like there are no targeted images of it. For many other small outer moons they did take repeated images for light curves, phase functions and so on, but not Aegir apparently.

Aegir was never targeted by Cassini. I considered it for June 2015, but due to the uncertain ephemeris and competition with other targets, this did not happen.
From the 38 irregular moons of Saturn known to date, 25 were successfully observed:
Phoebe
All Inuits: Kiviuq, Ijiraq, Paaliaq, Siarnaq, Tarqeq.
All Gallic: Albiorix, Bebhionn, Erriapus, Tarvos.
15 Nordic: Bergelmir, Bestla, Fornjot, Greip, Hati, Hyrrokkin, Kari, Loge, Mundilfari, Narvi, Skathi, Skoll, Suttungr, Thrymr, Ymir.
Attempted, but not successful due to mis-pointing were observations of Surtur, Jarnsaxa, and S/2004_S12.

PS: I started to compile all available information of Cassini observations of irregular moons on my website, including individual sites for each moon. By coincidence, the Aegir page is already near completion. It can be found here:
