Yes, for sure.
We have a professional Quality Control team. 
They will check carefully for each item we received from suppliers and manufacturers to avoid sending defective goods to our customers.
If an item is found defective in our QC test, it will be returned to the supplier / factory. 
So please don't worry about receiving a defective item because we are committed to being a trustworthy and reliable seller on international on-line shopping market. 

It's better to buy a cleaning fluid for lens filter. 

The filter is made out of the Professional Optical Glasses, and multiple layer nanometer coating 

I don't see why not, remember that the filter goes on the lens, not on the camera. 

This filter will fit any lens with a 49mm filter thread
