Opteka Flash Diffuser for the Canon 580EX II Speedlite Flash

The Opteka flash diffuser creates a diffused bare bulb effect, giving even coverage across the entire frame, with lenses from 15mm to 200mm in the 35mm format (and equal in other formats as well). The Clearmax diffuser is easy to use and goes onto and off the flash in seconds with custom fitting and no touch fastener. Designed for years of service without the bulk of some other diffusers, it is small enough to fit easily into a gadget bag or pocket.

Doc fetch goes through Layer's Aerospike pull-through cache; cache hit served the row without touching turbopuffer. The similar query asks Layer for nearest neighbors of the stored product vector — queries don't go through the doc cache, so no cache header is set.
