The following opinions have been automatically translated with Microsoft Translator. | Pentax K-50 Pros: tropicalization, double ring, pentaprisma, essentiality, ergonomics, sensor, photographic astro use Cons: autofocus that can be improved Opinion: We are at the end of 2020 and I decided to review this product after years of use. I'm one of the lucky ones who didn't encounter the magnet problem. This reflex also fits perfectly for astro photographic use as it uses a sensor with good efficiency and low noise. I am in love with his ergonomics and the pentaprisma used. I prefer it to other products and I will return to buy a Pentax in the future. sent on November 21, 2020 |
 | Samyang 14mm f/2.8 IF ED UMC Aspherical Pros: Full Frame Compatible, Focal Length, Brightness Cons: Sharpness at the corners on Full Frame, fixed lampshade, not for everyone Opinion: I'm actually using the Cine version of this optics that is in all respects equal to the photographic one with the only difference of having the toothed gapps, that of the opening "decliccated" and the greater fire race. By its nature this optics introduces the distortions that are expected but easy to correct in post-production. Better to use this optics on machines with APS-C or Super 35mm sensors because on Full Frame it shows a marked loss of sharpness and detail at the edges associated with the type of elliptical optics that makes you lose focus right in those places. The mechanics are well made and the lampshade is fixed and not removable robust but if it breaks for some reason you will be forced to change the entire body of the lens (so treat it well this lens). All the talk about the use of ND filters and so on you have to accept it and know before the purchase as well as you have to have clear ideas about its use. It is unlikely that it will not be the optics that you will use the most, indeed, but when used intelligently and sparingly it is definitely a focal and related type of constructive appropriate and targeted. sent on September 09, 2019 |
 | Panasonic Lumix G 100-300mm f/4-5.6 II OIS Pros: Solution, incisiveness, chromaticity, vignetting, chromatic rendering, weight, size, anti-dust, protected by splashing water, also works at low temperatures, hood, stabilizer, fluidity of the zoom ring Cons: Lack of zoom lock (but not a problem), it adds up Opinion: When you buy an optic like this I already know what you are looking for and want, so I do not go into surplus descriptions. "This product left me literally astonished because I did not expect great results and instead I was literally" shocked " If I think about the current market value I'm even more surprised and you'll forgive me if I let you say that in my nourished optic park this is the best (subjective opinion). rnWe're sorry, I found a great lens resolution, incisiveness and an incredibly natural and pasty bokeh despite the seven blades of the diaphragm. There is no noticeable presence of chromaticity that for charity will be there but cropping the picture I can not see in any way and no focal length.rnThe vignetting is limited.rnEasy to describe is the chromatic rendering can not be due to the obvious (visually) treatment of the lenses or to others but the colors are faithful and acc es, do not turn them on the heat upThe cold. The "bellows" of the zoom I remember being dust-proof, sketch-proof and able to work at low temperatures has a gentle, hard, soft, gentle manual excursion that does not allow for a casual ride during use transport (there is no manual zoom block, but it does not work in this case) .rnThe image stabilizer is incredibly efficient considering the focal length and is a delight to use it.rnThis optic is equipped with its indispensable hood, weight and size transmitting a feeling of "balance" and practicality. "I'm absolutely convinced that this lens will give many satisfaction to anyone looking for an optical product in this focal range. sent on November 11, 2017 |
 | Tamron 14-150mm f/3.5-5.8 Di III Pros: Zoom Lock; Practicality; Good quality optical; Construction; Filter size; Precise and silent AF; Supplied hood Cons: Not tropicalized; Not stabilized; Absence of a carrying case; Brightness (but not too) Opinion: I have combined this optic to a Panasonic Lumix GX-80 without any malfunction (with the latest firmware 1.2, both body and optics, total compatibility). The Panasonic Lumix GX-80 Panasonic Lumix GX- The GX80 has an excellent internal system that acts on the sensor and is handled properly with this combination. By having a "handy" optic and having a fairly wide focal length I would expect to see the presence of chromaticity and instead I was pleasantly surprised by the optical quality Of this Tamron.rnOther to maintain a good inconsistency of unknown phenomena marked with chromaticity (which is but is really contained), the lateral flare resistance is very good and the presence of the supplied standard hinge helps. If there is image distortion (Surely there) I know very little and the presence of the mechanical lock system of the zoom that prevents it from escaping during transport is a A buWhat you do. Mechanical construction is good considering the current cost and soft plastic ring guides are precise and comfortable to use. The size of the small filter makes sure that the cost of these accessories does not impact on a product rated "convenience of use" , Since it's a "do everything" thing. RnThere is no tropicalization but at that point the body machine should be. RnI am very pleased with this Tamron zoom for micro 4/3 systems but maybe I should say I'm very surprised at her Practical performance. sent on June 17, 2017 |
 | Samyang 100mm f/2.8 ED UMC Macro Pros: Optical quality, construction, intenal focus, 1: 1 Cons: Absence of AF and stabilizer considering the cost and what the other brands offer (just wanting to find "counter") Opinion: I am one of those who is fully satisfied with the performance of this lens that offers a good quality and robustness. I think the words are of little use and talking will be the pictures but if I have to find fault with them (that they are not, in my This is because more or less at the same price (at least at this time) there are valid alternatives that do not need to be named.rnAll the The rest is "poetry", both in the macro and in the middle of the canvas, provided that you have the patience and the ability to know how to use it as it should. sent on May 04, 2017 |

 | Samyang 24mm T/1.5 ED AS UMC Pros: opening, optical scheme, focal length, distortion (the focal view) Cons: Precision ferrules and opening fire (some specimens), flare, chromatic, plastic ferrules Opinion: It returned easier to speak first of the problems with this view and state that non'è was the first lens Samyang I posseduto.rnIl my copy was suffering from a marked play (slack) of the focus ring that made him unmanageable accurately and fast in video.rnCome if not enough the aperture setting ring (opening) was not only inaccurate but also noisy which made the use of optics unfit for its scopo.rnTrà the focus ring and iris ring can not absolutely give a positive opinion for this version, everything was over the Mark2 improved in these frangenti.rnLa optical quality can not judge trà the best because plagued by lateral chromatic, flare (possibly physiological for these focal lengths) and a marked phenomenon of refraction to the depths field estreme.rnDopo two substitutions I found a correct specimen is mechanically and optically but it is fair to warn the buyer of those that could be the drawbacks of this film series dThe Samyang. sent on March 24, 2017 |
 | Samyang 12mm f/2.0 NCS CS Pros: Size and weight, sharpness, brightness Cons: backlit performance, can give "habituation" Opinion: Before choosing this perspective I have read many reviews, both technical and those supplied by the users / clients. The quality-cost ratio is high but this I can only say now that I've got to try it. My version is matched with a body Panasonic / Lumix GX80 machine on which no backlash Bayonet / plug not known. The ring of fire system is manageable, not too hard but not too soft. Maybe I would have preferred a slightly wider / deeper ring but also goes so well. This combination, at least in my case, has proved successful in so far as known not so high a level of chromatism / overt as described by numerous tests (in which I believe, to point) and that indeed find rather content. The fire control system used by the GX80 (peacking focus in particular) is ideal to take advantage of optics such as this that over the whole offers a good brightness. The geometry of the image are well controlled, unknown obvious tendencies of "coloraction "of the image. The weight and size do not create any problem in practical use in every situation and nitidizza is very high on any field (in general). In backlight suffers a little bit of flare and the use of the lens hood is unavoidable (which seems only normal considering that we are talking about a wide angle.) the more the more it gives me pleasure to use ... which could cause problems when one needs to change perspective.

 | Samyang 50mm f/1.4 AS UMC Pros: footprint; ring pleasant to use fire; detail / sharpness; chromatic aberration; bokhe; construction; brightness; colors Cons: AF absent; infiltration powder; slight image distortion; flare; Canon "challenging" Opinion: I do not want too much circled around, this non'è perspective "for all" in my opinion. It can give so much satisfaction as "frustration" if you are not aware of his "nature." Using it on Canon camera bodies, being completely manual type, can become very "challenging" for beginners or enthusiasts of photography, for those looking for the "click" stolen and immediate. I am sure that these "prerogatives" turn away many from this choice and I honestly think it's a real shame. To make the best use this perspective must be reflected on the shoot you want to do and you have to take all the time needed to prepare it. The focus ring is really valuable, perhaps less geared down because of its precision and although it helps to improve the "speed" in finding the proper focus you will find that this aspect can introduce inaccuracies and in turn take longer than you as3Buso. After this long "introduction" I speak a little optics. The pros and cons have not read them, but I want to focus on ease that dust from entering into the optical path as the optical complex at "bellows" non'è sealed up front that flows freely in the main diaphragm. I tried to compensate by using a good filter that considering the considerable size has a cost. The absence of AF is a "crime" given the results that I'm getting and the overall sharpness. Apart from a bokeh for a great perspective of this cost and a "colorimetry" hot which keeps "the imprint" Samyang impressed me how optically sincere. Chromatic aberrations are very contained. A slight image distortion is perceptible only if you look for and non'è annoying at all (is corrected in post production with ease, but I have not yet felt the need). Therevignetting I never considered a problem, and frankly I do not see a lot. When there is light side, even using the lens hood, known some flare on the image but nothing annoying. The building is great, the nuts are precise and easy to use. Weight and size I like a lot in conjunction with my setup. I took photos under certain conditions convey a sense of "magic" and in conjunction with the 6D and systems with Full Frame sensors conisdero it an attractive choice. Ultimately perspective from "amateurs", not a reference but a sincere and honest product that will "warm hearts" of those who will have the zeal to choose it. Not recommended for beginners or those who does not harbor any desire to have a thought and reasoned approach to photography. Not for all. Compared to the "fifty" Canon this offers much more but as against has no immediate learning curve / use because of a focusing system pleasant fire, but all too accurate. personalmente I initially just "adopted" and then make him the "prodigal son." It gets better at higher costs but I love it (and in the past I have also owned the Sigma 50mm F1.4 Art). sent on January 04, 2017 |
 | Panasonic Lumix G Macro 30mm f/2.8 ASPH OIS Pros: Sharpness, chromatic correction, field correction, manual use, Macro, sufficient brightness, weight, dimensions Cons: auto focus not always precise, no tropicalized, no haze, flare, stabilizer Opinion: There are few things to say about this lens.rnTo take advantage of the dual stabilization on Panasonic machine bodies you have to upgrade with firmware 1.1 to climb and Dual IS2 from firmware version 1.2.rnThe optical stabilizer performs its function but with firmware 1.1 i do not has left completely satisfied (other products make much better) but since the release of the firmware 1.2 things have improved. rnThick incisiveness, chromaticity in all its shapes, crisp and offers a well laid out field without any distortion of the image. The macro function (1: 1) is really exploitable, subject to one centimeter of the lens being focused without problems but I can focus even when the subject hits the lens I have protected with a neutral filter.rn Applied to the Panasonic GX80 car body knows some hardness and slowness of the Auto Focus in the sense that often more efforts are needed to be able to reach the fire that once found is perfect (front / rear focus absent) .rn I also want to be lThis is the only optic I possess that has this behavior (Sigma 60mm F2.8 works better, for example). rn My impression is that since the GX80 is coming out of the box, there may be a form of non-perfect implementation the two units in fact with the firmware 1.2 seems to behave better but it is still "not perfect" from this point of view. The absence of tropicalization is a pity, but the weight and the total size contained make it go in the background I'm also looking at the great handling and "enjoyability" of using it in a manual way. My sample suffers from flare in backlight and / or light shining that I brilliantly solved using a rubber hood. The shots made with this optic, considering also l 'current commercial value, they are almost "magic." Ideal for those who want to get closer to MACRO photography without engaging very economically but not just. rnPiaceable in every respect, building and mate includedi.rn sent on September 27, 2016 |
 | Samyang 35mm f/1.4 AS UMC Pros: Detail / sharpness, contrast, bokeh, ergonomics, manual focus, cost / performance ratio, resistance to flare, chromatic content Cons: fixing ring hood and filters, dimensions, weight, not weather sealed Opinion: Despite other opinions, which shows the subjectivity of some factors, I find that the adoption of a focusing system manual focus emphasizes the pleasure of use and better the end result. The focal length of 35mm, moreover, are still unable to cope well even in manual thanks to a generous and precise focus ring fuoco.rnLa mechanical construction is good but I find questionable quality (plastic ring) located on the main body where it is applied to the lens hood and the inner edge which is screwed a possible filtro.rnQuesta "crown" is not too strong and the plastic tends to flex when put under pressure, may create some difficulties in the hood locking phases and my case has created some small discounts when screwing on the UV filter (but nothing as "striking"). rnDettaglio and sharpness are very good already just one stop away from F1.4, a value that has a blurred pasty and natural without create a great loss of detail on sog sent on May 09, 2016 |
