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), it is still a valid purchase, with the awareness of the objective limits of this lens.
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
