The following opinions have been automatically translated with Microsoft Translator. | Sigma 150-600mm f/5-6.3 DG OS HSM S Pros: image quality, image stabilization, AF speed, construction of tank Cons: Absurd the front lens cap in fabric, will need a cap 105mm Opinion: I own this lens for a few days, Deputy Tamron 150-600. Constructively is spectacular, all-metal, solid, sturdy, a pleasure to observe it and have it in your hands, by a feeling of "pro". Excellent optical quality at all focal lengths, 600mm and wide open is very clear and for me, in spite of the various tests, is greater than the Tamron and it shows (engraved image more, less thick and especially with virtually no chromatic aberration) . The image stabilization is very effective when set to Dynamic (with dock usb, mandatory in my opinion), factory stabilizes less. Autofocus spectacular and even here the difference is clear as the Tamron speed and engagement decision. Fantastic customization settings C1 / C2 and the switch to limit the distance maf (which in any case you can customize the Dock). rnOttima also bracket for tripod that overturned become a convenient carrying handle. rnIl weight is definitely importanyou, why this lens advice to those who have already had to deal with superzoom lighter and therefore know how it is managed. For me when the hand held I have no particular problems thanks to the stabilization of the primacy ... of course they are not objectives to carry around all day but a few hours you tranquillamente.rnL'unico defect is, in my judgment , that 'obrobrio hood lens cap ... I'd like to talk to a Sigma engineer to explain where I put this thing when you do not, it does not fit in your pocket and not always turns with the backpack ... already we proceeded to order a cap " classic "105mm :) rnDa note is the important vignetting at full aperture, it corrects with a click so I do not consider myself a big problem. rnConsiglio given the reduced pdc these focal lengths, double-check the maf is likely that there is a need for adjustments, especially on dense sensors (I had a slight front focus on the D810). rnQuesto is the definitive telezoom, above him there are only fixed ... sent on August 14, 2016 |
 | Sigma 24-105mm f/4 DG OS HSM Art Pros: excellent construction, overall quality, and af stabilizer excellent Cons: Vignetting F4, front-clear focus but solved with machine calibration Opinion: I own this lens for about a month, with a Nikon D810. Preferred to 24-120 of the Japanese home, I immediately realized that he had made a great choice. Out of the box gives a feeling of solidity and strength. Offers qualitatively very sharp images (after I calibrated the AF which I'll discuss later) at all focal lengths, even at full aperture. Cartoon a lot in this situation, particularly to 24mm but is corrected in one click and much better chromatic aberration that plagues Nikon, practically absent here. Excellent also the hood that engages in a safe and stable to lente.rnL'unica found flaw was an obvious front-focus, with the focus placed chart and calibrating the lens in the car ... the increase in performance has been evident and even photos that previously seemed sharp as they have become even more so, considering the crop at 100%. therefore recommend checking the calibration, as should always be done properly to avoid exploiting the lenses 60% .rnrnrnrn sent on May 30, 2016 |
 | Nikon D810 Pros: dynamic range, impressive detail, customization of keys and functions Cons: For now only the lack of U1 and U2 that, although the prerogative of bodies with commands not pro, they are extremely comfortable ... Opinion: I 'using this fantastic reflex from a few days before I had a D7100. Pro body, keys in the right place and customizations crazy, even the settings menu (autofocus, etc etc) controls can be customized in 4 different ways and can be saved as A, B, C, D convenient thing to divide the various photographic genres. fantastic and darkened viewfinder thanks to the curtain, inside, no more hateful cap to be put instead of the eyepiece! :) Good rnImpugnatura that transmits a remarkable feeling of solidity, of course, the weight is felt, but those who buy cars like these is usually the last thing on pensa.rnTenuta ISO in my opinion very good, used to the D7100 which amok detail .. .it is true, the grain can be seen but it is very manageable to at least ISO 6400 maintains exceptional detail, color noise invasive but can be removed with a click. Do not forget that the sensor has very 36MP and inevitably will be a little 'less than FF less dense. rnAnche the problem Icromosso I have not found particularly in any case much more problematic on the D7100 thanks to the density and size minori.rnUltima thing for now, the click is quiet and it has particularly colpito.rnL'unica negative note I, which cmq I was thoroughly prepared, is the lack of customization U1 and U2, very useful when changing genre (for example, from landscape to bird life where you change several settings), you could think of putting a couple of frets more ... rnAggiornerò this review in time when I knew better the car. sent on May 08, 2016 |
