Field of view at 24mm is noticeably narrow in the ones I have looked through. AFOV around 40 deg at this fl. The Baader Hyperion Mark III states 50 deg at 24mm. Better, but basically "plossl". But maybe that is not an issue for Planetary observing? Also try to get one that promises to be parfocal through the zoom range.
