Glass display case...
It looks like your camera focused on the glass case and not on the cameras. You could try manually focusing on your subject.
Not the best of photo situatiions.
As suggested by RV and CPR, a CPOL, with its decrease in light, or getting closer to the glass will help.
I use a rubber lens hood right up against the glass to eliminate any reflections. If my lens is short enough, while holding the camera, I extend my left index finger, tip against the glass, which provides some steadiness and eliminates vibration from the glass. The tripod suggestion is a good one! Wide open and close will maybe minimize the thick cracks in the glass, too.
