Sigma 40mm F1.4 DG HSM Art For SONY SE Fit Black 332965

Product Information

This lens's two biggest negative factors are the wide-aperture color blur and the strong pincushion distortion at short focus distances.

APS-C format cameras using lenses projecting a full-frame-sized image circle avoid most vignetting problems. The image below is a 100% crop taken from the top-left corner of a Sony Alpha 1 image captured at f/1.4 (on a moonlit night). Omitting the optical stabilization system reduces the size, weight, complexity, and cost of a lens. Sigma provides a 1-year limited warranty, and Sigma USA provides a limited 3-year warranty extension.As an E-mount user I prefer the 35mm 1.2 Art, but this 40mm lens features better correction of longitudinal CA and even better coma correction. The Sigma 50mm F1.4 DG DN Art Lens vs. Sony FE 50mm f/1.2 GM Lens comparison shows the Sigma lens is slightly lighter and narrower. Like all Sigma Art glass, the 40mm F1.4 is built to last. Treat this lens as an investment and it should outlive several camera bodies. Should you buy it?

Vignetting is correctable during post-processing, with increased noise in the brightened areas the penalty, or it can be embraced, using the effect to draw the viewer's eye to the center of the frame. In this case, the just-over one-stop of corner shading showing at f/1.4 may be visible in select images, primarily those with a solid color (such as a blue sky) in the corners.Regarding the Sony E-mount version of this lens, Sigma develops, manufactures, and sells lenses based on the specifications of the E-mount, disclosed by Sony Corporation under license agreement.

We didn't experience very much "hunting" at all, either in good or bad light, with the lens accurately focusing almost all of the time. It's also a very quiet performer, thanks to the built-in HSM (Hyper Sonic Motor), which makes this lens well-suited to video recording. The front element features Sigma’s water and oil repellent coating, which is designed to repel water drops and provide resistance to fingerprints Generally, the more a lens diaphragm is stopped down, the larger and better shaped the sunstars tend to be.The image quality comparison shows the Sony lens slightly sharper in the center of the frame at f/1.2 Except for a small number of specialty lenses, the wide aperture bokeh in the frame's corner does not produce round defocused highlights, with these effects taking on a cat's eye shape due to a form of mechanical vignetting. The Sigma 50mm F1.4 DG DN Art Lens vs. Sigma 50mm f/1.4 DG HSM Art Lens comparison shows the DN lens is slightly narrower, slightly longer, and modestly lighter. This is a huge boon for astrophotographers who want even detail clear across the frame. I will say there is a healthy amount of vignetting to be corrected but I was very pleased with the f/1.4 performance. Obviously when the aperture is stopped down image quality only improves: the vignetting goes away and sharpness only gets better. This is a very sharp lens. This lens delivers tons of detail across the frame. The edge of the frame is equally impressive, if not more. Instead of describing every result in detail we focused on the performance at the maximum relative aperture. In that case on the edge of the APS-C/DX sensor the lens exceeds 44 lpmm and on the very demanding edge of full frame it reached almost 43 lpmm. Such performance means just one thing: with a very sensible angle of view, amounting to 57 degrees, the tested Sigma doesn’t have to be stopped down at all to achieve sensational sharpness across the frame.

Price: The lens currently sells for 1200 EUR (incl. 19% VAT) / 1400 USD. The Sony ZA is the most expensive lens in this trio at 1500 EUR/USD with the Zeiss Batis in between at 1300 EUR/USD. [0] This is essentially average for a 50mm lens, but not as useful as the magnification figure on most 35mm lenses. This is among the most stunning lenses I’ve ever used. Sigma has churned out win after win with its Art lenses. From the light vignette at f/1.4, to smooth bokeh, it’s a perfect choice for portraiture. It’s not a headshot lens, but for full-body or environmental portraits, it yields dreamy results. Perhaps the best thing I can say about the autofocus on this lens is that it works about how you would expect. It’s not going to break any records for speed, but it’s reliable, predictable, and effective. HandlingEspecially ultra-wide aperture lenses are expected to show strong peripheral shading wide at the widest aperture settings when used on a camera that utilizes its entire image circle. And there is something else: onion ring structures are noticeably less pronounced compared to the Sigma 35mm 1.4 Art. Sharpness infinity I took this to an equestrian show with my family and just for fun. Then I shot almost exclusively at f/1.4 just to see what this lens could do. That angle of view drives subject distance choices (or meets distance-related requirements), and subject distances determine perspective. Yes. It’s expensive, but the Sigma 40mm Art is a wonderful lens that will impress even the most seasoned photographers.
