Review on Meike 12mm f2.8 Ultra Wide Angle Fixed Lens with Removable Hood for Fujifilm Mirrorless Cameras: Compatible with X-T Series, X-Pro Series, X-E Series, X-A Series, and More APS-C Models by Diane Ferreira

Some reviewers noted that these lenses can be a bit quirky. However, I was surprised to find that the lens I received actually focused beyond infinity! Normally, when we move the focusing mandrel from near to far, we expect the ring to stop exactly at infinity. This lens rotates well past the point where infinity would be in focus. The infinity mark on the barrel is also shifted past the registration mark. If it matches the mark, the focus is close to infinity. I did a little dyno test, focusing on objects at different distances from the camera. The distance markings on the lens are as accurate as possible. The infinity marker in the center of the registration line is as accurate as one would expect. You need to learn that in order to photograph distant subjects, you need to focus indefinitely, not just rotate the ring and expect everything to be fine. Like I said, a little strange. I would say that my lens is defective. But around the same time I also bought a 25mm Maike lens with the same X-mount. This lens has the exact same "feature" so I'm assuming they are products. It would certainly make production a lot easier if you didn't have to very precisely time the end of the drum rotation to the "exact" infinity point. Maybe that helps them offer a decent lens at such a low price. Also, these lenses suit me very well. I won't put them on a rig or take critical architectural photos (I've done this with a survey camera in the past). Sharpness is good and colors are well saturated, if a bit muted. unlike some of the more expensive lenses where the colors really pop. Both internal and external glare are controlled surprisingly well. For serious amateur and even professional work, these lenses are more than adequate. Keep in mind that this filter can make your expensive flagship lens worse than the unprotected Meike unless you've paid a hefty sum and chosen a carefully chosen UV filter for your lens. And these lenses cost less than the best filters! These makeups remind me of quality lenses from the 60's and 70's. Improvements in design, manufacturing and coatings have made today's best (most expensive!) lenses better than generations ago. However, many of the great photos were, and perhaps still are, taken using decades-old technology. The low cost means we can afford to buy spare and interchangeable lenses and experiment with many more focal lengths and other features than we could with modern lenses. Combined with a very portable camera, this is far more valuable to me than the latest technology.
