Pictures taken using the 77mm camera lens filter look stunning having resemblance of a kaleidoscopic effect. It's entirely done optically by transforming the front lens barrel into a multi point capture to get unique perspectives.

Effect can be rotated around using its built in ring. Although one gripe I have is this filter has a rather sim 2.5mm width barrel and can easily get stuck onto lenses if tightened down excessively making it difficult to remove.

On a 77mm filter thread, it has a high precision thread alignment and is easy to screw onto the front of most large DSLR lenses. While the built in 360 rotating front element operates soo smoothly its only slightly heard when capturing video. Photography wise this filter creates an awesome visual look to images making them artistic and colorful.

Filter is also much heavier and bulkier than I initially figured with a rounded fisheye style front although it doesn't alter camera perspective, only creating this creative layer of repetitive pattern known as a kaleidoscope. Aperture was increased by 1/2 to 2 notches to balance out its reduced light that this filter creates from a dense optical refraction but it can vary between DSLRs and mirrorless cameras since its meant to be universally compatible fit.

Images are sharp in the center with noticeable overlapping and blurring towards the edges with limited color fringing or noisy aberrations. Great optical effect that is creative and a lot of fun to play with bringing a unique perspective to digital photography.
