Yes — this is generally a flare/internal reflection issue that can appear on the RX100 II, especially when shooting toward the sun or in strong backlight. It isn’t unique to this camera, but some users do report a noticeable purple/blue spot with this model.

What you can do:

• Reframe slightly or change the shooting angle.
• Shade the lens with your hand or another object if the light source is just outside the frame.
• If the sun or bright light is in the frame, flare may be unavoidable.
• Some users report that opening the aperture can reduce the effect in certain situations.
• If needed, remove the flare later in editing.

A traditional lens hood is usually the standard flare solution, but on a compact camera like the RX100 II it’s not very practical, and if the flare is caused by internal reflections in backlit scenes, a hood may not help much.

So the short answer: it’s a known flare behavior in this kind of shooting, and there’s no guaranteed fix other than changing composition, shading the lens when possible, or editing afterward.
