I am disappointed. well, in a circle. I've been in cinema for over 23 years. As a professional DOP, I mainly rent for large projects. But this time I decided to buy this for a project I had just before Christmas. I thought I might miss the chance that my local rental house didn't have a high end speed amp available. The best you can buy costs around $600-700. I couldn't justify it at the time, so I bought this one. However, I'm glad I bought it because the rental house didn't have it. So it could be worse. But see, this product is fine if you just want to focus manually. I wanted auto focus for a backstage piece I was planning to do for my YouTube channel. (At 312,000 subscribers and averaging 220,000 views per year per video) but the BTS I wanted to do for this never happened because it was very slow with the auto focus or in some cases didn't work at all. And to clarify, I bought an EF -M2- II. I bought their latest and not the best speed booster. but me Excitedly these guys tried to help us with EVERYTHING by making a product that was hand tied for its market and competition at a ridiculous price. Kudos and thanks for making this product. It works and it's a lot cheaper than the competition. Thanks for that. It just needs improvement. There's plenty of firmware for that. Finding the exact version that works well for you can be a daunting task. Thank you Viltrox but please clear this up because we love love love you for really trying to save us all big bucks.
