>>4481438Tilt-shift lens needs bigger good quality image circle than not-ts of same focal length, using movements move the frame off the optical axis of lens. That, mechanics and low demand add the cost up.
Samyang has less expensive tilt-shift lenses. Also medium format lens to dslr/mirrorless tilt-shift adapters exist (dunno how $$$ wide angle medium format lenses are). If you want a toy Lensbaby may still be a thing.
I've only used large format camera movements myself.asjhy
