The Lizars Challenge Dayspool is an early British-made rollfilm folding camera, sold by the Glasgow optical retailer J. Lizars as part of its Challenge range. It falls into the late-Victorian and Edwardian amateur camera category, positioned as a compact daylight-loading option for general photographic use.

At recent UK auction, hammer prices for the Challenge Dayspool have sat in a narrow £130–£150 band, with the two recorded results giving a median around £137. With only a couple of saleroom appearances on record, today's value is heavily condition-dependent and a clean, complete example with working shutter tends to sell for more than a tired one.
