Pentax O-LW74A Front Lens Cap

The Pentax O-LW74A is a dedicated front lens cap designed specifically for the HD Pentax-D FA 21mm f/2.4 ED Limited DC WR lens. It provides essential protection for the front glass element against scratches, dust, and moisture when the lens is not in use. This accessory is intended for owners of that specific limited-edition lens seeking a replacement or spare cap.

Snap-On Installation and Fit

The cap installs by pressing the centre pinch mechanism to open the jaws and releasing it over the lens front. It is sized precisely for the 21mm f/2.4 Limited lens, so it will not fit other diameters or thread sizes. The most common issue is losing the small cap during shooting sessions, so tethering it or storing it in a pocket immediately after removal is advisable.

Durable Everyday Protection

The cap maintains a secure friction fit over extended periods in a camera bag, resisting accidental dislodgement during transport. Its construction shields the front element from environmental dust and moisture during long-term storage. It is not designed for impact protection if the camera is dropped, nor does it replace a filter for shooting in harsh conditions like blowing sand or heavy rain.

Questions about this item

How do I confirm the O-LW74A cap is seated correctly on my HD Pentax-D FA 21mm f/2.4ED Limited DC WR lens?

Press the cap gently until it clicks onto the front element; the silver finish should sit flush with the barrel and the lens will be shielded from scratches, dust and moisture.

What comes in the box with the O-LW74A and is anything else needed to use it?

The package contains the silver front lens cap only; no extra parts or tools are required — simply snap it onto the compatible 21mm f/2.4 Limited lens.

Which version of the O-LW74A should I choose for the HD Pentax-D FA 21mm f/2.4ED Limited DC WR lens?

The O-LW74A is a single silver model built specifically for that lens, so there are no alternative versions or capacities to select.
