I think the canon speed booster for the C70 is one of the best I have seen , and also the metabones booster are pretty solid choice the vitlrox ones I have had are good I think alot of it comes down to adjusting the back focus on them correctly ...so its not so much about quality of image but is it set up correctly for focusing I think thats were people have issues ...there was lump of extra glue in a viltrox SB I had which stop it focusing correctly once the glue was remove it was fine .....so your milage may vary with these
Great video. In your experience, is there any loss of image quality with a speed booster?
