The fact that you can pair it with the 1.4x and 2x teleconverters is the icing on an already rich proverbial cake - fitting the 2x tc extends the reach to a whopping 914mm in 35mm full-frame terms, albeit with a slow maximum aperture of f/11. Optically sharp at almost every aperture and focal length, yet compact and light enough to carry around all day, in all conditions thanks to being fully weather-proof, there really isn't too much to complain about. This is the newest member of the XF lens range - so new that it's only just gone on sale - but as we discovered in our in-depth review, it's the best all round telephoto zoom lens for Fuji X cameras. We've also included the shorter 50-140mm because it's the only constant aperture zoom for Fuji cameras, and because you can also fit a 1.4x or 2x teleconverter to extend its range and make it more comparable to the others. There are now four excellent telephoto zoom lenses to choose from for Fuji X-series camera owners, ranging from the 55-200mm up to the 100-400mm, with the 70-300mm positioned between them in terms of size and price. I’ve drawn some figures on the pictures with Photoshop Elements I haven’t edited them in any other way.Which is the best Fujifilm telephoto zoom lens? That's just become a much more difficult question to answer with the recent introduction of the XF 70-300mm. To minimize camera shake, I mounted the phone on a tripod and took these pictures hands-off, using the self-timer. These boring pictures are meant to test the lenses, not to sell them. If you’re having trouble unscrewing the macro and wide-angle lenses, slip the end of a wide rubber band over the rim of the macro lens to protect it, grip it gently with pliers, and grip the rim of the wide-angle lens with your fingers.

And you may be keeping your phone in a protective case that increases the distance between the phone’s lens and the clip-on lens. Some phones have protruding cameras others don’t. There’s no provision for dealing with variations in the distance of the clip-on lens from the phone’s lens.Unless you’re careful, you may seat the lens at an angle rather than flush against the phone’s case.There’s no way to make sure the center of a clip-on lens is aligned with the center of the camera’s lens.The clip-on mounting system is imprecise and insecure so it’s liable to distort your pictures. When I grope around in it for a lens, I risk getting the lenses dirty with my fingers, because they don’t have enough caps. The drawstring doesn’t close the bag very well, so they fall out. The velvet bag doesn’t work well for storage. Because they don’t have inside lens caps like serious lenses do, they’re harder to keep clean. The lenses have metal barrels I was expecting plastic. There are no instructions the most informative text I’ve found is Amazon’s product description. The set consists of a macro lens, a wide-angle lens with lens cap (and these two lenses arrive screwed together), a fisheye lens with lens cap, a plastic clip with a threaded opening that holds a lens, and a velvet bag. I wasn’t able to center the lens on the iPhone 6’s camera because the clip mount was on the edge of the phone’s body that may have made the distortion worse. The black corners are the lens’ interior, as if we were looking out of a tunnel, because the lens isn’t wide enough for the job. Notice that the balcony in the top left is out of focus.

Quick sample: The “red hall” photo at the top of this post is a fisheye lens shot, using a tripod and self-timer.

If you still want to buy them, save yourself money and grief by ordering the identical product on Amazon.

The best use of these lenses would be as a gift to a child. The important question is “Would these lenses help me take better pictures with my phone?” Two quick pieces of advice: Now let’s take a close look at their product. I’ve already written about the vile practices of the LUX HD450 company. “The power of a $2,000 DSLR in your pocket!” If only it were true.
