If not, the f/4 is a reasonable option and it does save a considerable amount of money. If you enjoy night photography or plan on taking it up, I would recommend purchasing the f/2.8 as the wider aperture will make a big difference. Your choice, independent of budget, depends on what you will be photographing. An aperture of f/2.8 is ideal for night photography. $999 for the Canon 16-35mm f/4), you won’t need another to photograph the night sky. Even though it’s a more expensive lens ($1,999 vs. That being said, the benefit of the Canon 16-35mm f/2.8 is that it also is a great lens for night photography. Each lens should perform equally well at their optimal apertures (though I would have a look at the reviews of the lenses before purchasing.) The cost between a 16-35mm f/2.8 and a 16-35mm f/4 zoom is at least twice the price. If a landscape photo is taken on both those lenses at f/11 would you see the difference between the two?Īwnser: Not really since the sweet spot for the 16-35 f/2.8 is between f/5.6 and f/8, and for the 16-35 f/4, it’s between f/8 and f/11. Kevin also had a second question touching on the same topic: In fact, it’s a whole lot better than f/4 and you’ll see a big difference between them even though they’re both considered open apertures. Take this image as an example: A wide aperture was used to blur out the background treesĪ wide aperture such as f/2.8 is also ideal for night photography. Using a wide aperture is a great way to emphasize the focus on a specific object. Yes, f/7.1-f/11 will result in the in-focus parts being at the sharpest (as Kevin said, a good depth of field throughout) but that’s not always what we’re looking for in an image.įor example, if you’re photographing in a foggy forest and there’s one tree that stands out, you can use a wide aperture such as f/2.8 to make the background/surroundings soft. Do You Need f/2.8 for Landscape Photography?Įven though the sweet spot is at f/11, it doesn’t mean that’s the best aperture for all images. As I talk about in our Introduction to Aperture in Landscape Photography, an aperture such as f/22 will have more of the image in focus but it won’t be as sharp as an aperture such as f/8.Ī wide aperture such as f/2.8 or f/4 results in less of the image being in focus but the in-focus parts are sharper than what they would have been at a more narrow aperture. GREAT FOR TRAVELING because it’s light weight, and is a fast lens (big aperture f1.8) the 50mm is a great addition to your bag for trips. This range has the apertures which result in the overall sharpest images. A faster lens with an aperture of f/2.8 will have its sweet spot between f/5.6 and f/8. For a lens with the widest aperture of f/4, that means the sweet spot is between f/8 and f/11. The sweet spot of a lens is located two to three steps out from the widest aperture.
