help lens redrock

Hi there - I´m posting this video here to show what kind of look we were able to achieve using the HVX200 in 720p with the redrock M2 DOP adaptor and a Nikon 24 2.8 lens. I´ve been looking at a lot of material from other users who have the same set up but I´m not convinced I´m getting the same level of detail, quality and focus. Just wondering if someone has some input on this and what you think about the quality of the shots. Apparently we could get better results using a 50 1.4 lens so this kind of feedback is what I´m looking for and your thoughts in general. We´re planning on using the camera for comerial work and need to invest another 3-4K in additional redrock purchases but we want to make sure that the investment will be worth it. Thanks so much in advance!

here is the video
