There are a few things that are extremely important technical aspects for a great sports photo:
- Well exposed
- In focus
The Nikon D4 and the Sigma 120-300mm ƒ/2.8 DG OS HSM with the Sigma 2x converter helps me to get the moments and technically being just right.
The Sigma 120-300mm f/2.8 DG OS HSM Lens is a telephoto zoom lens featuring a fast, constant f/2.8 maximum aperture. This lens is the first lens designed under Sigma’s new Sports line of lenses, making it well-suited for fast-moving subjects such as wildlife, nature, aviation, racing, and other similar situations.
The built-in OS (Optical Stabilizer) system enables a reduction in the appearance of camera shake up to the equivalent of four stops, resulting in a long lens that can easily be used handheld and low-light conditions. The OS system is divided into two modes; one for general shooting applications, and one that is better suited for panning shots of moving subjects. The OS system can be further adjusted to suit your needs through the use of the USB Dock.

The Nikon D4 camera features a 16.2Mp 36 x 23.9mm CMOS sensor with Nikon’s FX-format and the EXPEED3 image processor. ISO sensitivity can now be extended as low as ISO 50 or as high as 204,800 with a standard range of 100-12,800 ISO. Additionally, 10 frames per second continuous shooting in FX-format for up to 200 shots ensures the decisive moment will not be missed.
D4’s AF sensor utilizes 51 strategically placed AF points that are designed to capture subjects as you choose: by working together like a net to capture moving subjects or for pinpoint accuracy. Use a single AF point to home in on the exact place on your chosen subject. Each of the 51 AF points delivers fast and accurate AF detection to an impressive low light level of -2 EV (ISO 100, 20ºC) with every AF NIKKOR lens – expect to shoot more smoothly at night stadium assignments, poorly lit indoor arenas, cathedrals, theaters and any other low-lit venues.
D4 aligns its 15 cross-type sensors in the center to detect contrast for both vertical and horizontal lines with lenses f/5.6 or faster. The five central points and three points to the left and right of them in the middle line are compatible with f/8. Which is to say that with the Sigma 2x converter the lens is ƒ/5.6 and the D4 could still autofocus in a low light level of -2 EV at ISO 100. I had a lot more light than that in the Georgia Dome.
