Back story: I don’t have a field monitor yet, so I rely on the screen on my gh5.So, on my first day of shooting some skate footage with my canon 8-15mm fisheye, the guys I was with were killing it! Everything was going so good, we were all so hyped when watching the footage back on the camera. So I get home and put the SD card in my MacBook, excited to watch my footage on a bigger screen and to my shock and horror, ALL THE FOOTAGE WAS BLURY. I couldn’t understand what could’ve possibly went wrong. Was it my new canon fisheye? Was it the Viltrox speedbooster? Was it my gh5? Well, after looking online to see if anyone has had similar experiences with infinity focus, I found a few videos explaining my exact problem. It turns out that the glass element in the Viltrox speedbooster is adjustable and that you have to turn in clockwise or counter clockwise to adjust the distance between the cameras sensor and the glass element in the speedbooster. In my case it was clockwise. After doing this a few times and fine tuning it, I can finally set my focus to infinity and get a sharp image. I still have to tell the guys that their footage looks like it was shot through a dirty beer mug, but at least next time will be better. So to anyone reading this, CHECK YOUR FOOTAGE ON A COMPUTER BEFORE TAKING IT OUT TO FILM ANYTHING WORTH A DAMN.By the way, the Viltrox EF-M2 ii is well built and does what it claims. I would recommend it to anyone thinking about purchasing one.
