Pros:Let Lightness, Fluidity ring put focus for manual work, detail and image quality
Cons:No one for what it costs
Opinion:I heard about this lens and not only that, I noticed around that several were buying it. I was headed for such a focal length but someone told me about the Tamron, especially for its macro factor, but I was not convinced. Finding myself in talks about this Viltrox I decided to buy it. To premise that I take photos and videos but I can tell you guys that in both cases I'm 20 is something spectacular. Never mind that it is plastic but gives you images worthy of a Pro level 20. My opinion? If I buy a Pro and it falls out of my hand or something like that I must first recover you from an imminent heart attack and then send it for assistance to no longer have the same optics. Here if I fall for it I throw it away and buy another 180 Euros " Hahahahahahaaaa " crazy 180 Euros. This perspective is the revelation that if a Brand wants it can produce inexpensive things, even if of poor material but which work excellently and I repeat for some equal to the pros. BUY IT IN THE MOST ABSOLUTE WAY AND YOU WILL NOT REGRET MY WORD
Pros:price, yield (with distinction), lightness, size, AF
Cons:Surrender (with distinction)
Opinion:Optics that are worth the money it costs and even more depending on the sensor on which it is used. On FF from 24 mpx it always offers a good performance in the center, acceptable at the edges from f/4, and good from f/5.6. Reliable AF without any particular slowdowns. Tested on nikon DX (which has the same density as the 45 mpx sensor of the nikon Z7) where it should have taken advantage of the best part of the optics, it was instead quite disappointing. Which makes me think that on dense sensors it gives poor results. However, it remains a very light and space-saving lens that can be an ideal match to carry with a 24-70 zoom for those situations where 24mm is not enough but you don't want to weigh down the bag both in terms of weight and investment.
Opinion:I'm talking about the Viltrox 20 mm f 2.8 mounted on Z6, if it was mounted on another camera body or on Sony the performance could change. Specimen centered, all corners return the same quality. Tested on some close and far shots comparing it with the old Nikon 20 mm f 2.8 and the Nikon AF-S 14-24 f 2.8: in both cases the Viltrox is better as a resolution, since it costs less than the FTZ adapter used I would say that it is better to leave the reflex lenses at home..... At the edges at f2.8 it loses something but nothing compared to the other lenses I compared it to. Basically a good purchase, better than any 20mm for reflex I've ever had (I don't know if it's equal to or equal to the AF-S 20mm f1.8 that I've never used). As always I can't say if my copy is "lucky" but I repeat, respect the price, the optics are excellent.
Pros:Exceptional price, light, sharp in the center, sharp throughout the frame when you close the aperture
Cons:Very pronounced curvature of field (which deteriorates the image at the edges at open apertures); "mustache" distortion (but easily correctable, given the existence of a special profile in Lightroom).
Opinion:It is a very cheap and extremely compact lens, very comfortable to take for a walk. The sharpness (tested on 24 mpx) in absolute terms is quite good, already at f2.8, at least in the center, as also emerges from various tests on the net (e.g. OpticalLimits). The big problem at the edges (and not only) is the extremely pronounced curvature of field: objects in the foreground or second to the focus are decidedly out of focus (and even if on the same plane, at f2.8 the edges are rather soft). Closing the aperture, from f 5.6 onwards (and even better at f8), the situation improves decisively. Distortion, moderate but complex ("wave" or "whisker"), if you use Lightroom or CameraRaw is not a problem, as there is a dedicated correction profile. The colors are neutral. The quality of the materials is good, even if my sample initially resisted being unscrewed by the camera (with use everything is back to normal). On the a7iii the focus is good and the focus motor is quite quiet (audible in absolute silence but much less noisy than the Sony 50 f1.8, for example). For what it costs (especially on offer), in my opinion it is still a valid purchase.
Opinion:It pays what it is worth, it is an economic lens whose merits are lightness and size. Unfortunately, the image quality is low at the edges and only acceptable in the center. It's worth spending a little more and getting a better lens. If you aim for image quality, I strongly advise against it.
Pros:Sharp in the center, light, not bulky, beautiful star lights, possibility to update it via usb, lens correction profile just added in the last raw camera, minimum focusing distance and last but not least the cost in relation to the quality.
Cons:The edges are the Achilles' heel. Some slight indecision on the A.F. but maybe it depends on my Sony r1 and r2 cameras a bit old night
Opinion:The "softness", I call it blurred, fades a lot at the smallest apertures, 5.6/11 and, for landscape use, it is only noticeable by enlarging to 100 or 200% as, in a fussy way, I generally do. I compared it with the other 20mm of good class that I own (Tokina cost double double weight and larger size) same subject, aperture, camera etc etc and, I repeat, in the center for me they are even while at the edges the difference is noticeable at higher magnifications. Another quality I didn't expect is the macro to large objects (flowers). Took better macro shots, for the wide focus, than those taken with a macro lens and micro shoe. So, as a subjective "technical" grade I would say 8.5. But optics must also be compared for other factors, first of all cost and portability and in this grade 10. Average 9.2 I recommend it. Yes of course, it won't be the lens that can no longer be removed from the camera but not having it in your bag would be a shame
Cons:Maybe no one... The barrel is made of plastic and is made of...
Opinion:Small, light and also very nice. But above all x Nikon Z !! A perspective that I have been waiting for a long time, to put in my backpack for incredible excursions. It works very well, Af ready and without indecision, very quiet. And then it is also sharp in the center a lot even at full aperture, while at the edges it improves from F4 onwards, but it doesn't matter x me yes because it is better than the Nikon AF-D 20mm 2.8 that I loved so much ... Absence of Flare, Ca even against the sun I don't see any (but did you test it well ?) But at that figure ... everything is granted, and Viltrox really granted us a small miracle. Good!!!! I don't know how it goes on other sensors, yes because actually some lenses go well with some sensors, but on my Z8 it is really good, but also on ZF and Z6II. S O R P R E N D E N T E !
Opinion:Like everyone else, I read reviews, including votes, and when I saw the rating that was given to this lens (8.3) I thought it was practically a glass with a cap. And I thought very badly. I certainly don't want to say that it's the ultimate lens, but in the evaluations you should consider everything, not just the benchmarks because it seems pretty clear that a lens over a thousand euros (e.g. the 20 Nikon) will probably be better than this one that costs 180. However, for a possible amount, you put in your bag a light, small, very well made glass with excellent performance. Seeing is believing. I read about flares and aberrations. Two problems that, if there were, don't exist for me, since I often go looking for flare and remove aberrations with a click. I strongly believe that in a Nikon Z kit (I have Z8 and Zf) it cannot be missing and can live happily and without any inferiority complex with lenses that cost more than ten times as much.
Opinion:The best advantage of this lens is its compactness, on the z5 it makes everything very portable. When combined with the 28 and 40, a very transportable layette is created. It can also be bought for less than 200 euros. Great job by viltrox. I'm hoping for a 65 f2 or a compact 90 style sigma dg dn line contemporany. The case supplied is better than the one that nikon gave me with the 105 mc ?

Pros:Compact, sharp and contrasty, low distortion, cost
Cons:Chromatic aberration
Opinion:Small and versatile lens for shooting points excellent for weddings or Street, I do not deny the perplexity about the distortion being a 20 mm, but I must say that all in all it is fine and it is much more controlled in this sense than the tamron, for what it costs and for the focal length that it is in my opinion offers a sulperior image quality to a smartphone and in addition stylistically speaking it is not that you can show up for wedding with the latest generation mobile phone to make a service
Opinion:Tiny but substantial optics, very light and decidedly compact, well built like all Viltroxes, ideal for itinerant use when you need to be light. It is very easy to update the firmware with a USB cable, which is obviously always recommended. Already very sharp at full aperture, excellent contrast and brilliance of the colors, f2.8 seems almost the best aperture, closing it improves only at the edges as these at t.a. are slightly out of focus due to curvature of field, nothing serious however, in practical use in my opinion it is almost not noticeable, if you then close a hair the out of focus disappears completely. Very close minimum focus with very good blur (when you can produce it), very good resistance to backlight. Finally an incredible price, also taking this into account this I would give a nice 10
