Pros: Excellent construction. General optical quality truly remarkable. Although f / 1.8 is not huge and is within the standard Micro 4/3 in terms of weights and dimensions. Auto Focus. Tropicalization.
Cons: Lack of mechanism (style clutch) for manual focus. Moderate chromatic aberrations.
Opinion: It states that this is not a real review, but a collection of first impressions about the Olympus 8mm f / 1.8 PRO I've got to buy and which I am very satisfied. As I will have to test it and know him better, I will update this article. A little consideration deserves this little / big goal is the only in the world with Fisheye f / 1.8. Even in other camera systems you can find an equivalent with which to compare it. In this sense, Olympus has done an outstanding job and, as per tradition, offers a unique product of its kind. Initially, when I got to try it to Olympus Day, I not included in full and thought it pretty excessive a Fisheye with its characteristics, including price. You considered an exercise in style, a bit 'of academy, its placing on the market; actually I was wrong. The 8mm PRO carves out its own space within the range of the Nissan and although it is a target with particular vocations, on thein ductility in practice (and for those who have clear ideas on how to use it) it makes it really interesting. QUALITY 'CONSTRUCTION: in line with the PRO range of Olympus, really well put together. I love the ring of focus (the only one present), because it offers increased strength and fluidity to target high-end. Sin to use it just because the lens is equipped with AF motor. The absence of the mechanism for manual focus (style clutch) present in the other PRO may annoy some and in fact, especially for astrophotography, have an indication of the distances of focus would have facilitated not a little. They might not have wanted to include not affect the dimensions. Finally missing the Fn key, but personally I do not consider a specific disability. SIZE AND WEIGHT: to be a Fisheye is not a feather, but it is absolutely in line with the philosophy Micro 4/3 so for those holding the weights and dimensions to say that there are absolutely no problems. On an E-M5 II it is perfectly bilanCiato and use it in any condition and for hours does not involve minimal effort / hassle. SPEED 'AF: although not a splinter as other objectives of the range, it is absolutely adequate, both in terms of speed and accuracy. Above all we must remember that it is a Fisheye and there do photo hunting, then go looking for the millisecond less it seems really unnecessary. QUALITY 'OPTIC: I would say that here follows the performance of his brothers of the PRO line. The sharpness at the center is very good and what is more surprising is that already at f / 1.8 the yield is significant and close to f / 2 - f / 2.8 - f / 4 - f / 5.6 - f / 8 is not It serves to improve slightly in the middle, while to benefit most will be the outer portion of the frame, where a greater impact will be most noticeable. Color and contrast are those of the PRO line, then good results from this point of view and buyers already know in advance what beatersttarsi. Chromatic aberration is RESISTANCE FLARES: here the 8mm part of the list of objectives of 'human'. Of course, we speak of a lens with an angle of view of 180 ° and chromatic aberrations can not not exist. I do not have much direct experience with the Fisheye of competition, but all I saw the presence of Purple Fringing in certain conditions, ie with scenes where there are areas of high contrast. What changes is that there are those who digests better and some less. The 8mm, from what I have seen so far, it seems decent but not stratospheric. To suffer the most are mainly the edges. Fortunately in post production you can be remedied. Regarding the flares, you have to be careful how you shoot and where there is the sun. Generally flares appear only if you include the sun in the frame; are not too intrusive though (here the work of the anti-reflective coating on the lenses you see). Sometimes they are also accompanied by some halo of purplish-greenish. Invitation always still thinking about the type of lens (its optical design very complex) and also the use which I do, which involves a considerable stress because I love shooting with the front light. Use my inevitably shows that all characteristics and early 'defect' optics. Analyzed these aspects, I would say that this goal even when shooting video has many applications and its incredible brightness will be a plus not just in terms of lighting situations. If we add the tropicalization, the minimum distance of focus (only 2.5 cm of the front element, stuff that you have to be careful not to scratch it), I would conclude by saying that all these features with a Fisheye expands, and not just , the areas of use which are commonly assigned to this kind of objectives. Stay up to highly specialized optics, but Olympus have managed to give it a personality all its own that makes it really attractive to those who can look at it with the eyes right. |
