Hmm... Can you list some name? I haven't seen any like that. Most of canon's large aperture lenses suffer from LoCA although they have excellent Lateral CA control.
Before I list a few here, I would like to put the APO designation in context. With the exception of the Otii, APO has been used mostly for relatively fast telephoto lenses in the past. It's said that APO design doesn't work well on WA/UWA so it's a wasted effort; I don't understand optical design well enough to know why. You have some SuperAchromat (better corrected than APO) 50ish 135-format lenses but they're all slow. Only recently, that you see Zeiss and Leica would label their fast 50 as APO (or even 85). With that, I would consider lenses like the Canon 200/2 (or even the 1.8), 300/2.8 and longer top L lenses to be APO. Some of the Zeiss and Leica lenses were labelled as APO (say 200/2 APO-Sonnar or the APO Cron) is not as "APO" as you would think by today standards. Heck Tamron and Sigma used to label indiscriminately many of their lenses as APO.
