Minolta Spotmeter F or the Pentax Spotmeter V are you cheapest options but they still go for a good amount.
You could use a phone lightmeter app that lets you digital zoom in, it works surprisingly well
>>3590930Was f/8 at half a second to 2 seconds don't remember exactly, but I was using a tripod and the Voigtlander Apo-Lanthar 90mm.
Pic related was f/2 at 1/30th with the Canon 35mm f/2 LTM
