Have the cage bought directly from Rollei! With my Sony A7s a perfect team! Looks very valuable and feel is top notch. Everything sits without wobble or creak, the handle is super practical and indispensable! I wanted to on both sides ... Have the front instead of a matte my ring light attached HDR300 of F & V and need now only the Atomos Shogun as an external monitor! Then I'm perfectly happy! The price will hopefully fall a little ... All in all, strong buy recommendation!
