Pros: Stability at all openings, sharpness, price, weight

Cons: Minimum excursion over 1 metre for manual focus

Opinion: The 20mm f 1.8 is a great lens. Excellent construction, constancy at all openings and usability in hyperfocal. I think are just two different uses: 1) to f 1.8 or large openings is a difficult but creative lens, the angle of the 20mm with minimal distortion, helps in artistic compositions. Huge blurred very homogenoe great three-dimensionality. However, it is difficult to focus which, by force of things, is slow; 2) with larger closures the 20mm behaves well and, in hyperfocal, is very fast, easier to use. Under the artistic profile, my eye reads better than the wide angles and this samyang comes after being a supporter of the Sigma 24mm. Here the angle is predominant and surely the possibilities it offers are remarkable. As in all Samyang, the focus ring, with a perfect consistency, equal to that of the diaphragm, has a scale according to me not real and the distance between 1 metre and infinity is entrusted to about 1 cm of rotation, becoming in this complex way to Infan or based on distance. This for me is the only flaw of a magic lens and character. With warm and fuzzy colors very creamy, without losing a good dowry of sharpness, constant from TA to maximum closure. I recommend the purchase to those looking for a quality lens and, of course, a bit complex because of the manual, at a low price. Used to date between 250 and 300 euros, but if there are few, indication that the owners do not exchange. I also recommend it to those who photograph landscapes, in these cases it is obviously much easier to manage. Tested on both Canon 6d and M5 (although I do not think I would ever use it with the 22mm) I found it funny, with the need to take a little hand on distances. The Testero in street and portraiture (obviously set), my styles.

Pros: Constant sharpness at all apertures, three-dimensionality in portraits and closeup, diffraction at low apertures, blurry soft and gradual, not too large, the possibility of mounting filters

Cons: flare and star at times intrusive and difficult to handle, the aperture ring that becomes stiff in cold temperatures and inaccurate between f22 and f16, too sensitive to the cleaning of the front lens, is not the pattern of lines for the depth of focus

Opinion: since in many ask me an opinion and which are now in possession of this lens for over two months and I have used in many situations, I decided to have my say indicating all the pros and cons I first notato..rnle impressions were very positive, the outside is like all other Samyang, mostly plastic, but the ring of focus and is very fluid and at the same time well-glazed, once put in place, there is no delay, the bayonet metal is perfectly tolerance and the game is correct, once the game is minimal mounted .. despite the materials you still have a good feeling of strength holding it in his hand; despite its small size weighs a lot, the 13 internal lenses feel .. the lens hood and caps are always the usual black plastic, the cap Samyang standard 77mmrnora what we use: the first tests I made are about to flare, ghost and star on lights, which appeared to be the most critical features .. the star on the light pointsvery good according to my personal taste, begins already to be present at f4, f5.6 is already quite evident, at f11 for me it has the best starry closing because even the rays begin to be more intrusive, and some quite annoying situations .. on ff they do not give big problems, but if used on aps-c or m4 / 3 starry could occupy much of the picture; Despite this contrast, and colors in the picture remain faithful, there are no major drops in contrast / sharpness / saturation as often happens in other objectives .. With the light source within the frame is almost always seen a flare that crosses the photo especially in some situations creates a purple / magenta stain on the bottom of the frame which is quite intrusive, if the light point is out of the picture, I never had halos or contrast losses, the lens hood is designed quite probably well .. rnora another sore point: sharpness ... sharpness is never extreme, the picture is always slightly '' spalmatin '' when compared to known very clear objectives, however, that differences can be appreciated only at magnifications next to or over 100% .. the frame is very homogeneous up to 3/4, after which the sides and corners are always a bit 'disappointing, even stopping down does not have a big gain, there is an opening in which the sharpness is constant everywhere unfortunately; But already at 1.8 it is amazing, especially in the center, almost there is no difference by stopping even different stop .. RNLA distortion is almost absent when it focuses at infinity, in developing closer focus the distortion increases, it it is always a barrel distortion easily solved in post..rnora everything about the astrophoto: vignetting mind to 1.8, closing at 2.8 the gain is low enough, you have to go to 5.6 to eliminate almost entirely the coma .. unfortunately there is, I can not deny, however, is best knownthe brightest stars and stretching the corners is barely perceptible, the topic about the objective presentation I put the (artistically horrible) sample photos with a 100% crop of the center and the corners .. I also noticed an annoying aberration spherical, which makes the stars magenta or green in the case of a very light out of focus, the ring in the vicinity of infinity is very sensitive and at times I found it difficult to perfect focus .. I still have to say that for a whole nightscapes with starry skies performs well, you can not use and defects are never limitanti..rnora some personal opinion based on the use .. rnper very ambientati portraits is giving me lots of satisfaction, I find it very three-dimensional, with a yield on the subject that makes it almost palpable, the TA is blurry soft and progressive in all circumstances, even in the most difficult situations .. vignetting does not bother, the slight distortion probably helps, for this use I love it ... for ritrparticular acts in which a short throw and a must, such as photos in a car, for me it fantastico..rnnelle '' macro '' / macro is very well expressed, the focusing distance is minimal , the subject remains a few millimeters from the front lens .. blurred even closing, I remain quite soft and clean (put some pictures where it is very visible), the distortion to a minimum focus distance increases enough, which accentuates even more perspective, and I could even feel it a virtue .. diffraction minimum is also closing a lot, the sharpness of the subject is almost unchanged and always more than enough to landscape f16..rnl'utilizzo is perhaps the one that suits him less because of the flare and sharpness of the decline at the edges, but I have to say that even here the diffraction is minimal even f16, so you can take good pictures with foreground subjects, keeping everything in focus, without worrying too much about the calo general sharpness which entails diffrazione..rnper the astrophoto I have already expressed before, for the architecture I do not have much to say because it's a genre that just is not practical, I can only reiterate the distortion almost nulla..rnora some notes General : the use of filters is possible, I have tried mounting two slim filters and vignetting is very marginal, with a slim filter is nothing, so far we have .. I though a sore .. very closing the diaphragm there is a vignetting on the corners, vignetting where there is a blue dominance (probably changes according to the filter) .. I also have to say that this blue vignetting is present in f16, or in addition, even if the filter is not mounted .. is however much less accentuated and unobtrusive, also I noticed not only in certain conditions luce..rnla aperture ring perfect, at least in my lens .. if I close and then reopen to f22 to f16, f22 aperture remains at ... in practice I always have to go from f11 to f16 for assicurarmi to have the correct aperture; this thing takes place only between f22 and f16, all other openings are okrnè this distance scale, on my lens is right, sin is not present the typical pattern with lines that helps in using hyperfocal, I use it often and I feel their mancanza..rnmi also happened in special circumstances, with climates below -5 ° C, the aperture ring appears very tough .. the everything back to normal as soon carry the lens to milder temperatures ..rnultima thing: it is very sensitive to dirt on the front lens .. just a few grains of dust or fingerprint, to have a clear contrast to a decrease of the frame area, I used a lot of goals and I have never encountered such a sensitivity dirt .. can be a problem because photographing near the water, in the snow, in the dust, it takes no time to have a drop in quality, and clean the lens with a cloth outdoors it is notnever too sure, however, advise against the use of an ever mounted because the little dust protective lens that is formed between the front and protective glass lens really creates many problems to foto..rncredo've I said it all, in my opinion has nothing to envy none of the same focal length lenses and similar brightness on the market, is not without flaws, but they are all content .. for me the price is right, is giving me a lot of satisfaction and I never leave home .. I recommend it to everyone who do not fear the manual (1.8 is not so simple to focus because the transition zone '' in focus / out of focus '' is very soft and easily confuses the eye) they do not expect the extreme quality, but expect a lens that has its own character and that goes able to appreciate and better manage
