I personally love manual lenses, but I know most people prefer the convenience and reliability of autofocus, so it definitely serves a limited market. There was no sign of barreling. Note, the walkway on this bridge slopes slightly from the center to the edges to drain water. It's not lens distortion. Sharing its development concept with the SIGMA 30mm F1.4 DC DN | Contemporary, the 16mm F1.4 DC DN | Contemporary features a lens structure with 16 elements in 13 groups and includes the finest materials. This lens effectively minimizes optical aberrations and offers superb resolution at wide-open aperture and throughout the aperture range. The optical design and stepping motor deliver smooth autofocus during video shooting, while the mount features a special sealing for a dust- and splash-proof design.

So, for example, the figures for a 16MP sensor will be far lower than those for a 36MP or 50MP sensor. However, in relation to the sensor limit we can still evaluate the performance in terms of a description such as "very good" as well as the actual numbers. Two 16MP sensors could of course be directly compared.[/quote] It’s blazing fast every single time, even when it starts to get dark (though you can expect hunting if you try to shoot at, like, midnight). This guy DOES NOT sit still, so a sharp picture of him is a testament to the lens’s AF capabilities. AF-C/EyeAFI shoot with a wrist strap and was able to handhold & carry my setup around for a while without any hand fatigue.

SIGMA fp L will be supported by updating to firmware Ver.2.00 scheduled to be released in the near future, and SIGMA fp will be supported by updating to firmware which is scheduled to be released in April. Naturally, there’s not a whole of point in having a fast f/1.4 lens if image quality doesn’t hold up when shooting wide-open. As it turns out, sharpness and contrast are maintained very well at the widest aperture. Another bonus is that the wide aperture and short 25cm minimum focus distance enable a fairly tight depth of field and good bokeh, enabling interesting perspective effects.Edge sharpness is also creditable, being very good from f/1.4 to f/2.8, excellent at f/4 and f/5.6 and then very good at f/8 and f/11. Results are softer at the edges at f/16, but can still be described as good. yes, but there is an[quote]It has to be related to the theoretical maximum possible for a given sensor. First off, Sony actually recently released their own direct competitor to this lens: the Sony E 15mm F1.4 G. Like the 30mm F1.4 DC DN | Contemporary, the 16mm F1.4 DC DN | Contemporary features SIGMA’s latest design technologies to offer F1.4 brightness while minimizing optical aberrations. This lens is an absolute beast. It’s just as sharp, has rediculous autofocus (OEM Sony lens, of course) and features incredible G-series build quality.
