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

Product Information

La distorsione è minima, anche in post produzione in molti casi le correzioni eseguite per la distorsione dell'obiettivo sono davvero minime e in molti casi trascurabili. Sharpness is impressive even when shooting wide-open at f/1.4. At this aperture, you can get a really tight depth of field when shooting at fairly short focus distances. Bokeh (the quality of defocused areas) is pleasantly smooth and remains so when stopping down a little, helped by a well-rounded 9-blade diaphragm.

Here’s the Sigma 30mm f/1.4 EX DC along with the Canon EF 15mm f/2.8 Fisyeye, and the Canon EF 17-40mm f/4 L lens. Sigma 30mm f/1.4 EX DC Lens Looking at these examples and those in the sharpness section, there is no question that the 30mm f/1.4, with its very fast maximum aperture, smooth rendering and excellent sharpness at mid-to-close distances, is the best option for environmental portraits. It is closely followed by the 35mm f/1.8, while the 30mm f/2.8 can be used at a pinch. Flare, chromatic aberration, distortion Date un'occhiata a questo: [[ASIN:B00EUFTT62 Sony SEL1670Z Obiettivo con zoom E 16-70 mm F4 ZA OSS, Nero]] The 35mm f/1.8 and 30mm f/2.8, on the other hand, require a full turn or 3/4 turn respectively to go from infinity to the minimum focus distance regardless of the speed at which you turn the ring. Però ci sono alcune cose da considerare che possono variare la valutazione dell'acquisto a seconda delle esigenze di ciascuno di noi.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 tested the 30mm Contemporary with the 24MP Sony a6500. At f/1.4 the lens is sharp, notching 2,302 lines on a center-weighted Imatest evaluation. The lens delivers clarity that's just as sharp as the average, right up to the edge of the frame. That's better than the 1,800 lines we want to see at a bare minimum, but not quite what a 24MP sensor can deliver at its very best. 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.

This lens features Sigma HSM (Hyper Sonic Motor) for fast focusing similar to the competition, and it works as advertised on the Canon I used, but unfortunately the Sony version of Sigma 30mm f/1.4 EX DC Lens does not have any ssm (Super Sonic wave Motor) The Sigma 30mm f/1.4 EX DC Lens Sigma 30mm f/1.4 EX DC Lens – In Box It balances perfectly on my Sony a6000 and the massive focusing ring provides a really nice rubberized gripping point when out shooting.

The Sigma 30mm F1.4 DN is an exceptional performer, compared with its E-mount peers. Sharpness is not just high wide-open, it's also pretty well maintained across the field, falling off very gradually without any sudden drop near the edge (so there shouldn't be any nasty surprises at the corners.) As the lens is stopped down, sharpness improves across almost the entire frame,although much of the improvement ends up concentrated in the center 2/3 of the frame. The Sony 35mm f/1.8 is the only lens that is perfectly compatible with a6300’s PDAF system, which makes sense given that it is a Sony E lens. If you switch over to C-AF and Wide focus area, for example, the green PDAF squares will light up across the frame regardless of where your subject moves.

In this Hands On Sony Lens Review of the Sigma 30mm f/1.4 EX DC Lens I will cover everything you need to know, from a “Real World” Photographers perspective!!

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 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). Distorsión y Aberraciones: Terrible, no puedo adjetivarlo de otro modo, no me entra en la cabeza que una focal fija tenga una distorsión tan notable que llega casi a un 2% y es completamente apreciable a simple vista. Que si, que la cámara lo "corrige", y que hay perfil en los editores Raw... Pero es que no estamos hablando de un angular, en ese caso lo podría entender, el estupendo Sony 50 1.8 OSS no tiene distorsión, ni el baratisimo 30mm 3.5 macro, que es la misma focal. We tested the lens with a few cameras, including a Sony Alpha 6000, the new Alpha 6300 and an Alpha 7R in its APS-C crop mode, and it felt nicely balanced on each. It is fairly large for the focal length. Most of the other lenses I mentioned previously are smaller, almost pancake, but then they don’t have an f/1.4 aperture, which obviously requires larger elements. In stills terms, though, there's little real-world difference between the Sigma's 45mm equivalent view and the 52.5mm equivalent of the Sony. The difference between them doesn't suddenly open one up to a type of photography that couldn't be achieved with the other.

Unfortunately, to achieve such a clean and minimalistic lens barrel, they had to omit a physical AF/MF switch. It’s a bit annoying and probably my only major gripe with this lens. The lens is made in Japan - not Thailand, China, or Bangladesh. Build quality is completely decent. It's not pretending to be a vintage Leica or Nikkor, but it suits a modern Sony body quite nicely. Comparing the lenses at a closer distance – in this case, about 1.5 metres away from the subject – reveals a different story. In the following comparison, our aim is to discover just how they compare in terms of their usability, optical quality and performance, and in the process, help you figure out which is best for your photographic needs. Let’s get started! Only L-Mount and X Mount features mount with dust and splash resistant structure. It is not featured on Sony E mount, Canon EF-M mount, and Micro Four Thirds mount.This product is developed, manufactured and sold based on the specifications of E-mount which was disclosed by Sony Corporation under the license agreement with Sony Corporation. Reasonable size and weight, excellent image quality, large f/1.4 aperture, superior build quality and a good price all mean that the Sigma 30mm f/1.4 DC DN | C lens is worthy of the consideration of Sony E-mount users. The 50mm-equivalent lens is versatile, and a step up from existing Sony options at this focal length. Micro Four Thirds users have a great deal more choice within this focal length. Having said that, the f/1.4 aperture can only be matched by the more expensive Leica 25mm f/1.4 Summilux, and given the performance of the Sigma lens, it would be difficult to justify the extra money. Overall I am happy with the lens 🥳🥳. I would like to move closer and move away with Sigma 30mm to get a good shot rather than just rotating the zoom ring of SEL18135.
