Kipon have come out with their EF-FX AF version adaptor for Canon EF lens to Fuji mount recently. May 2018 the Kipon AF adapter is in stock at YL Camera. Price was slightly RM1000 which is much cheaper by 30-40% that the price of Metabones. So just pop over from my office to check it out. My testing gear was my EF400mm F4 DO USM IS Mark1 lens on my current body Fuji XT-2 of 2 years old. My main objective is to test whether my telephoto lens pairing up with a EF 1.4 X mark3 teleconverter is useable. This setup was to get better reach of 600mm x 1.5 = 900mm on my 1.5 cropped sensor Fuji body.
Distance of shot is about 50-60 ft in the shop. Firstly on the Auto Focusing in low light and low contrast condition focusing was a frustrating hunting affair and as such it is definately not good for my bird photography purpose. Even when it manage to focus the photo the shots were rather soft and blurry as shown in the photos below. Looks like it a no go for me to purchase the item.
Next I tried out the Kipon adapter without the 1.4x teleconverter, the focusing is still an issue but much better but then I was shooting at a shorter distance of 30-40 ft. Basing on the 3 shoots below I must say the case is a miss and hit situation. Possibility that my telelens is not properly suited to Fuji Af algorithm as the focus confirmation indicated otherwise...........
At a nearer target of 30 ft and on contrasting subject I got much improved shots as shown below in term of focussing and sharpness. Please note that my finding here relates to bird photography and the performance of Kipon adapter would be different for other EF L lenses. So for the moment I have to wait for a better birding solution...................
