The following opinions have been automatically translated with Google Translate.
Pros:– Sharp lens already at full opening (f/2,8) that gives the best of itself between f/4 and f/8 – Bokeh very pleasant – Simplicity of focus – Excellent construction, with small size – Cheap
Cons:– Deceinted ghiere (useful for video-takers) that do not resist any involuntary movements while holding the lens – Cap, without pressure lock, which is easily removed when the lens is stored in the backpack /bag. The lampshade (flower type) covers very little the lens and therefore can not keep it safe from possible bumps so we would have liked a cap with a better closure
Opinion:We had the opportunity to try this fisheye lens. We were very curious about the genre so we accepted many willingly to do tests. The lens is quite small in size (63x63mm). But despite its small size, the weight is felt: 275 grams of pure metal. The constructive aspect is undoubtedly one of the merits of this lens. In fact, bayonet and lampshade are metal and you hear it! You have suffered the feeling of robustness and solidity, characteristics that are not easily found in lenses of this price range (usually plastic, although this does not affect the quality of the lenses). The angle of field is 180 degrees on APSC and has a diaphragm consisting of as many as 11 slats. The lampshade, which as we said is made of metal, is embedded in the lens and is not removable. This lens does not support any type of filter. The lens is manual so you have to take a little hand, but thanks to the "focus peaking" function everything becomes easier. In our opinion, the absence of automation is not a defect especially when it allows production costs to be contained, with a reflection on the final price to the consumer. Our opinion is undoubtedly positive. If you are passionate about the genre it is a great solution with good value for money. For our photographic genre, it is not an indispensable lens so in the end we opted for the lighter Olympus 9mm
Pros:Funny, cheap, solid metal structure, brightness, sharpness.
Cons:Heaviness, cap falls easily, obvious chromatic aberrations
Opinion:I bought it without expecting too much, just to be able to take some more fun and particular photos. I fell in love with it. Not only for performance above expectations, but because I found that a Fisheye, at least one so good and practical to use, can be used, with a little imagination, in many situations. The structure is very solid, I was expecting the usual plastic, instead it is great, although obviously a bit heavy. The aberrations are there, but on the other hand from this kind of lens I expected them. The sharpness is really way above expectations. I have not encountered all these problems with the dials, remembering the really cheap price, I do not think you can ask much more, nor perfection.
Pros:Funny, crisp, cheap, solid, bright construction
Cons:Color aberration, falling cap
Opinion:One of the funniest lenses I have. It solves complicated situations on the go both as clutter and as results. In New York I took pictures that I couldn't have done otherwise. A lot of chromatic aberration but that easily rises in post-production. Pleasant ghiere even if that of the diaphragms is continuous and therefore not precise.
Pros:Great value, solid construction, good flare resistance.
Cons:Color aberration at the edges, but on M4/3 sensor is less intrusive for cropping. Diaphragms' ghiera frees, moves easily and should often be controlled.
Opinion:The use of a fisheye is always justified and limited to a few situations, so a low expense on a good quality perspective is advisable. This 7arts does not regret the little money spent ensuring a more than good performance with just a little chromatic aberration at the edges. With this in mind, manual focus is by no means limiting.
Pros:Cost, construction, overall make acceptable, covers the entire APS-C frame, vintage appearance and invoice.
Cons:Free diaphragms, no correction profiles in PP SW, soft ta
Opinion:Economic objective that honestly does its job. I have it for about a week but I used it intensively in various contexts to test it and possibly return it but I have to say that I am very very satisfied. Its best operating range is between 5.6/8/11. A more open diaphragms is soft, especially at the edges, although usable. At the diaphragm almost completely closed at 22 difraction manifests itself. The chromatic aberration as well as the flare, which I feared very much, actually I find both very contained. Mechanically it is unexceptionable but the diaphragms' diaphragms free requires attention and should be checked practically before each shot because it moves easily. The front lens is very protruding and the small fixed lampshade does little to protect it but this is inevitable. The front cap is well-crafted, must be put on the pressure on the lampshade and seems to hold well even if it is not mechanically blocked. Ultimately a very recommended optics that allows with a really minimal expense (just over 100 euros import) to have fun without giving up too much quality. I use it on the Sony A6000 and even if you have virtually everything in focus I always prefer to seal with the help of the camera's focus assist. Beware that in many post-production software the lens correction profile is not available and you are obliged to do the corrections by hand or using a profile of some other fisheye. EDIT of April 9, 2020. I confirm all the positives. In the period between the first review and the beginning of the virus quarantine I used the lens intensely and in various light conditions. The only flaw if the sun is framed is the flare that sometimes does not disturb and sometimes disturbs a lot. But I repeat... only with the sun framed. The judgment remains excellent. I can't wait for the virus quarantine to finish to continue using it!
