Since getting the new Canon XSi, I’ve taken quite a few nice shots. However, I knew that I couldn’t really take advantage of the camera until I got a professional quality primary, fixed focal length lens. The 18-55 telephoto that came with my camera kit was serviceable, but as those of us who do a lot of food photography know, the flash is not your friend. Really nice food photos are taken in ambient or natural light, and when you are in a restaurant environment, you REALLY don’t want to use a flash. And we also know that ambient light in environments where food is served can be challenging for food photography.
The downside of a telephoto lens is that the glass isn’t as big — the 18-55 kit lens for the XSi is 58mm wide, for example, so you don’t get as much light captured as say a 77mm wide lens. Having telephoto also reduces how wide you can open your aperture — the almighty F stop — which is key to natural light photography. A fixed focal length primary lens also allows you to shoot at a lower ISO rating in less light than a telephoto lens. So to summarize, Bigger glass, wider F stop, better food photos.
Having done some research on primary lenses, I finally settled on the newly released 50mm SIGMA F1.4 EX DG HSM. This comes in a Canon or a Nikon mount, and it streets for about $480.00. DPreview.com has a short write up of it here. Hey, I didn’t say the thing was cheap. Compared to the Canon L Series 50mm F 1.2 though at around $1400.00 which I originally wanted but Rachel would kick my ass if I went out and bought, I thought it was a bargain given this is state of the art lens technology. Canon also makes a 50mm 1.4 which sells for around $350.00, but it’s an older design, and I had a hard time getting one from online resellers without it being a special order item.
Here’s a photo of some grilled jumbo shrimp we made tonight, shot at f/2.5 ISO 500, using just the light in my kitchen. I’m barely scratching the surface of what this lens can do. Like driving a Ferrari, its a high performance product with quirks that the driver needs to adapt to. I’m finding that I have to bracket my exposures in aperture priority mode to finally get the image I want. With practice I should be able to tweak my depth of field just the way I want it. Hey, I’m a total gimp at real photography. Cut me some slack.
