🎃 Canon Ef 24Mm 1.4 Review
The Rokinon 24mm f1.4 isn’t a small lens, but it is about on par with Canon and Zeiss’s offerings. The lens is characterized by an extremely large focusing ring, a depth of field scale and an
This is an in-depth review of the Sigma 24mm f/1.4 DG HSM Art lens that was announced in February of 2015. Being a professional-grade wide-angle lens, the Sigma 24mm f/1.4 Art was made to challenge similar offerings from both Nikon and Canon, but at a much lower price point. Previously, Sigma had a lot of success with its Art-series lenses such
Image quality is excellent, but the price is a bit high for an f/2.8 lens. And of course, if quality is your concern more than budget, the Sony 24mm f/1.4 GM has first rate image quality, gathers twice as much light as the Sigma f/2, and has a de-clickable manual aperture ring, but it costs nearly $1000 more than the Viltrox.
Let me put the light gathering abilities of the Sigma 24mm F/1.8 lens in perspective. The Olympus 14-42mm f3.5-5.6 kit lens, at wide open aperture and set to a 24mm focal length, is an f/4.7 lens. Ouch. With the kit lens wide open and set to 24mm focal length, I need 1600 ISO to get a tripod shot of my kitchen at around 1/50th of a second.

The image from the rear-focusing Canon 55-250mm IS doesn't seem to change as it's focused. Color Rendition performance top. The color balance of this 55-250 seems the same as my other Canon EF lenses. Coma performance top. Coma, or saggital coma flare, is when points of light in the corners turn into batwing-shaped blobs.
The lens has a 24mm focal length equivalent to 38mm on a full frame. It features seven aperture blades that help to create a pleasing bokeh effect, and a minimum focus distance of 14cm. It also has a maximum aperture of f/1.4 that allows for very shallow depth of field. Performance. When tested, the 7Artisans Photoelectric 24mm f/1.4 Lens
Coma. With its maximum aperture of f/1.4, the Sigma 24mm f/1.4 Art is capable of gathering a lot of light, which might make it seem like a great lens for astrophotography. I photographed the Milky Way at different apertures and came to conclusion that the lens produces quite a bit of coma at both f/1.4 and f/2, as can be seen below: NIKON D750
The Canon EF 28mm f/1.8 USM Lens utilizes USM (Ultrasonic Motor) for quick and quiet autofocusing - much quieter than the same-focal-length Canon EF 28mm f/2.8 Lens . This is also a good thing. Focusing speed is similar to or a little faster than the f/2.8 version. FTM (Full Time Manual) Focusing is a nice feature in this lens.
The Canon EF 28mm f/1.8 looks appealing because I can find it for $200-300 and it's smaller and lighter than the Sigma, although it has some critical reviews regarding focus speeds. The Sigma 24mm f/1.4 DG HSM on the other hand has the benefit of being a stop faster at 1.4, though the lens itself is heavier and at least twice as expensive.
The incoming Sony 24mm f/1.4 GM weighs 15.7oz (445g), which means that the FE version of the 24 ART is some 73% heavier. Ouch! The lens also grows a fair bit in length, from about 3.55″ (90.2mm) to about 4 3/4″ (126mm) by my measurement.
