hi, im wondering if any of you guys have this problem. I recently tried cleaning my 45-70mm lens with a cleaning kit and after spraying the liquid onto the glass in front, i noticed the water seeped in from the side of glass and enters into the next layer. I am now able to see the wetness through the glass and i also noticed a few days beforehand that there are dust trapped inside and cant be removed. If i remembered correctly, the glass should be sealed tightly and will not allow dust, liquids and other foreign particles to enter. Can anyone enlighten me on what should i do? and if its possible for me to claim warranty for this. Thanks alot in advance
