This is related to the position of the viewfinder optical axis and the lens optical axis. You can compensate yourself after mastering the parallax offset.Regarding the lens: The viewfinder lens is an optical resin lens, and some slight dust or fine scratches are inevitable, which will not affect the use. If there is dust staining during use, just use air blowing. Do not wipe the lens excessively. The resin sheet is easy to scratch, especially do not use chemical solvents such as alcohol to wipe!Package:1 x 35mm viewfinder
