Baby Got Back Focus Chart shirt

This shirt is good for a laugh, followed by a good ol' fashioned back focus check. When you're in the field and feel like your focus just isn't hitting on those sweet snap zooms you love so much, treat your lens to a back focus check on this shirt. You probably shouldn't use this shirt for true, professional camera calibration, but if you're in the field, it's at least better than using a brick wall... and features clever wordplay.

Doc fetch goes through Layer's Aerospike pull-through cache; cache hit served the row without touching turbopuffer. The similar query re-embeds this product's title with CLIP-text and runs a vector query — queries don't go through the doc cache, so no cache header is set.
