Lens heritage
Rikenon 55mm f1.4
The Rikenon 55mm f/1.4 is a budget-friendly fast standard lens from Ricoh that delivers roughly 80% of the optical performance of legendary fast fifties at a fraction of the price, excelling for portraiture and artistic photography with smooth bokeh and warm color rendering.
We don’t have a record for this exact unit yet, so the history is for the closest lens family — specs may differ slightly.
