The focus ring is nice spacious and convenient to use. Its hardness is well calibrated for a palm grip, given the important size, but if you go to adjust with your fingertips as you are led more often to do, it is perhaps a little harder than the optimal comfort zone. However, it remains a pleasant experience. A great pity the lack of the diaphragm ring, but if it had to be without shots as in the Viltrox models with shorter focal length, perhaps it is better this way. On the side of the bayonet there is a micro USB port with which you can connect the lens to the PC in order to make firmware updates. The process is very simple, but the manufacturer could certainly engage a little more in the documentation (it is a couple of pages written on the fly with Word, without any formatting and with a lot of screenshots in Chinese), since it is not a 20 € plastic. But that's okay. What is not good at all is the mounting system of the hood: here it comes out of arrogance where Viltrox has saved: it is a system simply flawed and if I had not read negative comments about it before buying the lens, I would have considered it as defective. It is very hard to assemble and never goes to its seat on the first attempt. You have to stay there to try and try again with the risk of sliding everything to the ground, since it requires a lot of strength. Fortunately the plastic is quite resistant and at the moment I have not noticed fraying due to excessive handling. One word: very bad. I used this lens mainly for portrait photos and in different light conditions, and I must say that I am very satisfied with the returned look. The blur is extremely pleasant, the image is microcontrasted the right and the level of detail is elevated already to TA, to become excellent as soon as it closes by 1 stop. At F2.8 even at the edges everything is perfectly sharp. There is only one small, big problem: the lens suffers from chromatic aberration in an exaggerated way! Particularly in conditions of direct sunlight and in situations of strong contrast. If even a ray of sunlight falls on the subject, fuchsia bands appear on the edges. The serious thing is that the problem is also present in the center of the frame. And there is no way to limit the phenomenon in an acceptable way if not closing at F4! In the interiors or in shady areas there is no problem, but for TA photos under the sun, even of a faint autumn sunset, you have to take into account this big problem. The AF is quite responsive: in quiet situations the lens can easily keep up with the camera inputs. In the case of fast-moving subjects, such as a child running in our direction, we must take several photos in sequence to hope to have 1-2 in focus on the face. In short, fast but not a lightning bolt on X-T20. On two occasions I found the camera completely broken down with the lens that was constantly focus hunting: the first time it was resolved after a few seconds, the second time I had to restart the camera. It is difficult to say if it was a problem with the lens or a software glitch of the X-T20, but it seems right to report the problem. sent on November 09, 2021 |
 | Fujifilm XF 18-55 f/2.8-4R LM OIS Pros: Excellent build quality, sharpness, lightness, compactness Cons: Loss of sharpness at maximum opening, not ideal for those who make videos, powder that slips into the dials Opinion: With regard to this lens I heard so many words of praise that I influenced the purchase of my current body machine (which had it in kit, in fact). If, however, it is true that it is a kit objective with an extra gear, you should not pull the bar of expectations too high: its performance is not compatible with those of professional goals, as you often hear around. This is because its much-vaunted sharpness is higher than a normal kit lens, but fixeds of a certain level or professional zooms are another story. Moreover, at maximum opening, expect a rather marked drop of the same. Compared to its competitors, it is a classic 18-55 stabilized but offers an extra edge in the aspect of the opening (practically an extra stop) and the construction quality (entirely metal). If we exclude the MFT world, we can also add to the list the extreme compactness and lightness. Think that it manages to be perfectly balanced on an X-T20, a camera that in terms of weight and size could play in the same category (or almost) as smartphones. This compactness is paid for with a pronounced excursion to the outside of the inner barrel when used on the longer focals, but the excellent build quality makes sure that the structure remains stable and the excursion soft and without any clogging... but not exactly silent. If you find yourself making videos with this goal, remember not to zoom too fast if you don't want to hear the (albeit pleasant) whip of the barrel moving forward in the audio. And while you've avoided extreme focus changes, there's a pretty marked perspective distortion in the transaction. Another small feature is the fact that the dials have a texture of the right density to make you fit grains of dust that don't end. In general it is a product not without defects but certainly of high quality and can probably give you the best photos that you can take out from um lens belonging to the same category. Very happy with my choice to have taken it in kit, but I probably would not have bought it again separately, since it is still offered at a price that, honestly, is a bit high. sent on April 21, 2020 |
