Lens Cap: 43.5mm Lens Adaptor For Olympus Trip 35, 35 RC, PEN Cameras

The Olympus Trip 35, 35 RC and Pen cameras take a 43.5mm lens cap. They both however have an issue where the centre section of the lens protrudes a little, which means that modern lens caps don’t sit very well on the lens and can fall off rather easily.

In addition 43.5mm is a rare size for lens caps and filters.

A far better solution is to use a 43.5-46mm adaptor ring. This slim ring screws securely onto the camera lens and then has a 46mm filter thread. This enables regular 46mm (widely available) lens caps to sit very firmly on the lens.

You can also take advantage of the wide range of 46mm filters available.

Note that 46mm lens caps and filters are sold separately.
