This might be a great buy for some, but the claim that this setup "fits all DSLRs" isn't true. Not suitable for Nikon D800. Will not fit the Rokinon 85 cine lens which is designed for filming. No tracking focus, no matte boxing. It's a big disappointment that set me back a lot of time in the shooting schedule. The manufacturer of a product shouldn't say it will fit all DSLRs if it doesn't. This is a false product claim and a huge waste of time and money.
