Sigma 120-400mm f/4.5-5.6 AF APO DG OS HSM Telephoto Zoom Lens for Canon Digital SLR Cameras

The Sigma 120-400mm Zoom Lens incorporates Sigma's original OS (Optical Stabilizer) function. It offers the use of shutter speeds approximately 4 stops slower. Three SLD (Special Low Dispersion) glass elements provide excellent correction for chromatic aberration. This lens is equipped with a rear focus system that minimizes the fluctuation of aberration caused by focusing. It provides optimum image quality throughout the entire zoom range. The super multi-layer coating reduces flare and ghosting. High image quality is assured throughout the entire zoom range. The minimum focusing distance of 150cm (59.1") throughout the entire zoom range and maximum magnification of 1:4.2 make it useful for close-up photography. This lens incorporates a Hyper Sonic Motor (HSM), which ensures a quiet and high-speed AF as well as full-time manual focusing capability. The addition of the optical 1.4x EXDG APO or 2x EX DG APO Tele Converters produce a 168-560mm F6.3-8 MF ultra-telephoto zoom lens or a 240-800mm F9-11 MF ultra-telephoto zoom lens respectively.
Customer Review: Sigma 120 to 400 lens
I was looking for a long lens with stablization, this suited my needs. I ordered it with Amazon.com. I was hoping it would come prior to my trip which I was taking on my motorcycle. It came, great service from the dealer. I took the lens on the trip, used it extensively and love the pictures taken with it. Yes, it is a heavy lens, but I handheld it for the shots I took as had no room for tripod. Shots are sharp. As were taken mainly in the bright sun, had no issues with shake. Used the OS sometimes mainly to try it out more than needed. Overall love the lens and am happy with the purchase and would recommend the lens to anyone looking for a long lens.


I have been providing photography for corporate and special events for over 20 years. Our company is based in Palm Springs. There are quite a number of large resorts including the Marriott Desert Springs, Westin Mission Hills, La Quinta Resort, Renaissance Esmeralda Resort. Many companies hold their sales and incentive meetings at these resorts and frequently need photography. But what kind of photography?

It's very important for me as a photographer to ask the planner what they want to use the photography for. Are they going to use the photographs for a company newsletter? If so then I need to let the photographs be descriptive. They need to show what happened at the event, who was there, what they learned. Hopefully each photograph will tell the story of what the company did at their meeting and what their objective was.

What if the photographs are intended as gifts? Often, especially at incentive trips, the photographs are part of a thank-you gift to the attendees. In that case the photographer needs to capture images of the guests having a great time, enjoying the trip. Photographs that they might want to have in their home or in a scrap book. A favorite type of event to photograph is a multiple day incentive trip for a group of less than 200 people. The photographer can get to know the people and they get to know the photographer. Then it really shows in the photographs. People are more animated in the photograph. If they feel that their photographer is a friend, they they look at the camera in a different way. It shows in their face in the photograph. And the photographer has fun too!

We recently updated our website. As we were looking for photographs to put on the website it was clear when the people were having fun and knew the photographer, versus when the people didn't even though they were having fun. But the over riding objective when we photograph a corporate event is to make sure that we deliver what the planner wants with their photography.
