Clear protection for 40.5mm lenses
The OM SYSTEM PRF-D40.5 PRO is a clear protective filter with a 40.5mm thread. Its PRO designation means a thinner frame than the standard PRF-D40.5 model. Multi-coated glass reduces flare and maintains high light transmission. It shields the front element from scratches and dust without affecting image quality.
Compatible with select M.Zuiko and TG lenses
This filter fits the M.Zuiko Digital ED 14-42mm and 14-42mm L zoom lenses. It also works with the CLA-T01 conversion adapter for TG-series cameras. Photographers using other thread sizes or filter systems cannot use this unit. Buyers needing neutral density, polarising or coloured effects should look at different filter types.
40.5mm thread size
The single specification that decides fit is the 40.5mm front thread. Measure the lens barrel or check the manual for the Ø40.5 symbol before ordering. An incorrect diameter will prevent the filter from mounting. No step-up or step-down rings are included with this filter.

Questions about this item
How do I install the 40.5mm PRO filter on my M.Zuiko 14-42mm lens, and what step is often missed?
Screw the filter onto the lens front threads until snug; the thinner frame can feel looser than expected, so verify it is fully seated to avoid vignetting.
What maintenance or replacement will the multi-coated PRF-D40.5 PRO need over time?
Clean the black-rimmed glass with a microfibre cloth and lens fluid; replace the filter if the coating shows scratches or degradation that affects light transmission.
What limit appears first when using this clear protective filter continuously in bright conditions?
The multi-coated glass maintains transmission, but the thinner aluminium frame can transmit more heat to the lens barrel during prolonged exposure to direct sunlight.
