There's definitely something wrong. The images should be sharper than that. I would first open the shutter and shine a flashlight though the lens while looking through from the other side. This will tell you immediately if there is haze or fungus. Don't just look through it at a light bulb. Use a flashlight. If the lens is cloudy or has fungus or debris, etc, it would need to be cleaned out internally. If the lens is reasonably clean (moderate dust specks are not a big deal) then check for focus calibration issue.
