We aim to refine the sample of isolated early-type galaxies in the AMIGAcatalogue via high resolution imaging. Here we report the result from a pilotstudy investigating two candidates, KIG 685 and KIG 895, in K-band with thelaser guide star and wavefront sensing facility ARGOS} at LBT. Observations,obtained during commissioning time, achieved a PSF of ~0.25". We present thedata reduction and the PSF analysis from the best closed loop exposures toinvestigate the galaxies' morphological structure, including their nuclearregion. We used PROFILER for the decomposition of the azimuthal 1D lightdistribution and GALFIT for the 2D analysis, accounting for ARGOS's PSF. KIG685 was found to be a S0 galaxy and has been modeled with two Sersic componentsrepresenting a pseudo-bulge (n_{1D}=2.87+-0.21, n_{2D}=2.29+-0.10) and a disk(n_{1D}=0.95+-0.16, n_{2D}=0.78+-0.10). Nearly symmetric ring/shell-likestructures emerge after subtracting the GALFIT model from the image. KIG 895shows a clear irregular arm-like structure, in which the northern outer arm isreminiscent of a tail. The galaxy body is a disk, best fitted by a singleSersic profile (n_{1D}=1.22+-0.1; n_{2D}=1.32+-0.12), i.e. KIG 895 is abulge-less very late-type spiral. ARGOS high resolution images clearly revealedinteraction signatures in KIG 895. We suggest that the ring/shell likeresiduals in KIG 685, a "bona fide" early-type galaxy, point towards a pastaccretion event.
