Meike sent me this adapter to review, so here it is! I had been searching for a review on this speedbooster for ages, but couldn't find anything which made me hesitant to buy it. My aim with this video was to answer the questions I wish I knew when I was looking into buying it, and I hope it helps you in your decision as well!

If you want to buy the lens for yourself check them out on their website or on Amazon!
