Review: First one I got did not mount. Meike replaced it and now it works as expected - This is a revised review. The first adapter I received did not function properly because of a machining error on the bayonet. It wouldn't mount on my Red Komodo and it got stuck on my Komodo X. Because I didn't realize this until after 30 days, desertcart wouldn't take it back. Fortunately, Meike replced my adapter, and the new one works perfectly. It looks great optically and mounts on both Komodo and Komodo X. Thank you to Vincy and Meike for the help and customer service on this.
Review: On the APSC CAMERA, I got my wide angle back - We all know while we using the APSC camera, the most Awkward thing is we lost the wide angle capability. Please check out the photos as I attached, I’m using the sigma art 24 and 105 After I combo up with Meike 0.71x speed booster, camera recognized as 17mm and 74mm (of cause you need to x 1.6), but F stop open up to f1.0. I love the bokeh that 0.71x delivered to me, hope you guys whom are using the APSC, able enjoy the full frame alike photos
