5 out of 5 starsI am very happy with the results of this vortex prism filter with my Instax mini Evo camera with the adapter I purchased along with the filter.

5 out of 5 starsThe lens adapter fit perfectly on my Instax Mini Evo. With the adapter on, I can still turn the lens to change filters. The adapter also came with a lens cap, so now my mini Evo lens has protection, which I'm happy about. The two filters I purchased fit perfectly on the adapter. I am very happy with the purchase.

5 out of 5 starsI missed the last restock, so I reached out to RetrogradeENG to inquire about the future restock. I received a quick response letting me know that more were on the way and would be available shortly. Once I saw them back in stock, I quickly made my purchase! Just got to test it out on my Rollieflex along with the colored filters. Can’t wait to see the results!

5 out of 5 starsThe set of filters came in a nice case and were individually wrapped. Threads are nice and they fit perfectly into the accompanying sx-37 and bay 1 to 37mm adapters.
