Sigma 33B965 30 mm F1.4 DC DC Sony E-Mount-Black

Product Information

Gestire così tanto sfocato diventa moderatamente complicato in molte situazioni, e, a seconda delle riprese che bisogna fare in molti casi conviene acquistare la lente sigma 30mm f2.8 e con quello che si risparmia acquistare delle softbox o comunque dei faretti. There’s only fairly minor lateral chromatic aberration, which only tends to be visible towards the extreme corners of the frame. The optical path includes a double aspheric element, with the aim of optimizing image quality, with a reduction in spherical distortion, astigmatism and coma. The nine-blade diaphragm is well rounded and helps to maintain the quality of bokeh when narrowing the aperture.

I observed that the camera heats up slightly with Sigma 30 mm (which may drain the battery faster will have to test properly). On the other hand, I hardly have noticed this issue with SEL18135. In short, each lens seems to have its own set of strong and weak apertures. Despite being the least expensive lens in the trio, the 30mm f/2.8 performs extremely well at its fastest aperture and f/4 at long focus distances close to infinity, while the 30mm f/1.4 shines at closer focus distances, even at f/1.4 and f/2. The 35mm f/1.8 appears to be a good all-rounder, performing well at both close and long focus distances at the centre. Its only downfall is corner softness at the fastest values. BokehWe can say autofocus is somewhat goodish. But sometimes, it hunts. For 1-2 shots, it couldn’t focus at all. We need to rely on manual focus for those shots. It makes slight noise while focusing (compared to SEL18135, an absolute silent lens), but that wouldn’t bother you much. Downsides? HOLY PURPLE FRINGING, BATMAN! When shooting wide open, sometimes high contrast areas can exhibit signs of lateral chromatic aberration in the form of purple fringing. Yes, The Artist Formerly Known As Prince (may he rest in peace) would have loved this lens. There are a couple other things videographers might consider. The Sony's OSS and minimum aperture of F22 are both handy features. The OSS can help remove some shake when shooting handheld, and being able to stop down to F22 gives videographers a better chance to reach the 1/framerate video 'rule' that helps make video look smooth. Conclusion Nitidez: La nitidez está en el lado alto, aunque en su día lo comparé con el zoom de mi RX-10 y quedé decepcionado, después lo he comparado con otros objetivos (Sony E 35 1.8, Sony E 30 3.5 macro y Sony E 50 1.8) y es bastante bueno, mucho más que el Sony E 35mm 1.8 sobre todo en las esquinas y hasta f5.6 (Donde más o menos se igualan), está a la altura de mi Sony e 50mm 1.8 que es bastante bueno.

Part of the DN range of lenses for mirrorless cameras, the Sigma 30mm f/1.4 DC DN C ( Sigma 30mm f/1.4 DN) is a fast- aperture, third-party standard prime for Sony E-mount cameras. Taking into account the 1.5x crop factor on Sony APS-C sensors, the Sigma 30mm f/1.4 lens offers an equivalent 45mm focal length, making it a good option for a variety of subjects, including portraits and general use. We use Imatest SFR (spatial frequency response) charts and analysis software to plot lens resolution at the centre of the image frame, corners and mid-point distances, across the range of aperture settings and, with zoom lenses, at four different focal lengths. The tests also measure distortion and color fringing (chromatic aberration). All three lenses make room for a fly-by-wire focus ring on the barrel. Those of the 35mm and 30mm f/1.4 are ribbed while the 30mm f/2.8’s is perfectly smooth. We find the 30mm f/1.4’s the most pleasant to use, partly because the deep ridges make it easy to turn but also because it is made of rubber, which prevents it from becoming uncomfortably cold in low temperatures. However, the 35mm f/1.8 is the easiest lens to unmount because its focus ring takes up less space on the barrel than either of the other lenses. The Sigma 30mm f/2.8 is the most limited of the three since the PDAF squares only work in the very centre.The very first shot with Sigma 30mm made me realize that there is a sharpnesses advantage with this lens as compared to Sony SEL18135, even with daylight comparison. And in the low light, Sigma with a 1.4 aperture blows comparison away. Overall, I think the Sigma 30mm F1.4 is the perfect combination of build quality, size, and ergonomics. Perchè se prendete il 30 mm prima o poi inizierete a pensare all'acquisto di un grandangolo (con cifre che fanno dai 150 ai 300 euro), e di un 50/60mm (con costi che variano dai 300 ai 1000 euro) Here are several comparison images illustrating what different aperture’s produce using the same scene.

The difference between them doesn't suddenly open one up to a type of photography that couldn't be achieved with the other.

Close focus is available to 11.8 inches, fairly typical for a standard-angle lens. It's not a macro —maximum magnification is 1:7 life-size. You can work fairly close to subjects, just don't expect true macro results. Image Quality In manual focus mode, we found the fly-by-wire focus rings of all three lenses accurate and easy to use. As mentioned in the design section, our favourite focus ring is that of the 30mm f/1.4 because it is large, deeply ribbed and made of rubber. Our least favourite is the 30mm f/2.8’s mostly due to its smooth surface but also because quite cold to the touch in low temperatures.

The Sigma 30mm f/1.4 DC HSM Art is a high-quality ‘standard prime’ for APS-C format DSLRs

and many other brands) seem to ignore. This would be a good lens for hand-held, available light shooting, (although Y la aberración cromática lateral? a f1.4 es posiblemente la peor que he visto, algo mejora cerrando pero vamos ni con esas se acerca a otros objetivos... Aunque esto sí que se corrige fácilmente con Capture One o cualquier editor Raw pero si disparas en JPG es un problema. Alas, unboxing the lens revealed an immediate disappointment – no lens case! All of my other Sigma lenses (including the “Art” series) have included nice padded and zippered cases, so the exclusion of a case was a letdown. Tsk, tsk, Sigma... My poor "Contemporary" lens feels naked without a matching case.
