I am very happy with the purchase of product. The only problem with the lenses is vignetting at the corners and with the lens attached to hybrid nd filter it even becomes more. Sandmarc should try to solve this problem. Otherwise a good product to have. Enjoying the iPhone photography. Using the product on iphone 11 pro max.
I knew that the lenses are of the highest quality but did not know that Sandmarc service was so great! Recommend you to get this package. Nice to have a complete set. I sold my Ronin-S that I used with my Canon 5D Mark IV since I never got to use it because of all settings. Now I use a simple Firefly gimbal, Sandmarcs lenses and an iPhone 11 Pro and I actually get some stuff done. I did not understand that one case per lens was included so I ordered a case ending up with six cases. No problem at all to return the one I ordered by mistake. Sandmarc rocks and as a professional photographer I really enjoy not to have to bring all my Canon lenses, backpacks etc when just doing private stuff.
Good quality and look forward to using
