Avoid this by using Eye Detection autofocus. When creating portraits, for example, it’s easy to get sharp focus on a subject’s chin or nose rather than on their eyes. Face and Eye Detectionĭepth-of-field is shallow at large apertures and while this can be used to fantastic creative effect, it also means we have to be very accurate with focusing. Making images at wide apertures is much the same as making images with normal camera settings, although there are a few things we need to be aware of if we’re going to get the most from these superb lenses. Photo © Jacky Ley | XF200mmF2 R LM OIS WR: One for the professionals, this super telephoto lens boasts a massive F2 aperture, which not only produces exquisite background blur but allows for fast shutter speeds even in low light – essential for sports photography Although, to get seriously big apertures, you need to look towards prime lenses.
Some of our zooms have a widest aperture of F2.8 throughout their zoom range, like the XF16-55mmF2.8 R LM WR and XF50-140mmF2.8 R LM OIS WR.
LENS WITH BIG APERTURE SERIES
If you think a wide aperture lens might be useful in your approach to low-light photography, there are plenty of options in the X Series for you to choose from. Photo © Dianne Falcone Choosing a Fast Aperture Lens They also let you photograph with a shallower depth-of-field, which is great when you want to emphasize a pin-sharp subject against a soft, blurry background. In contrast, OIS and IBIS systems prevent blur from accidental camera movements, but not from moving subjects. This is why photographers sometimes call large aperture lenses ‘fast aperture lenses’, reflecting their ability to give fast shutter speeds even in low-light conditions.įast aperture lenses score over image stabilizers by not only helping to freeze camera shake, but also the movement of subjects, too.
In other words, it lets in 3.5 times more light, which is enough to transform a troublesome 1/10 sec into very usable 1/125 sec. To put things into perspective, creating images with a lens like the FUJINON XF56mmF1.2 R allows you to use an aperture that’s 3.5 stops wider than an XF18-55mmF2.8-4 R LM OIS lens used at 55mm. And shorter shutter speeds mean less chance of blur from camera shake, which can spoil images.
LENS WITH BIG APERTURE ISO
There are lots to choose from in the X Series, and they can transform your photographyīefore the days of image stabilization and high ISO sensitivities, photographers really only had one option if they wanted to make images handheld in low light: using a lens with a large maximum aperture.īy photographing with a large aperture – like F1.4 or F2 – more light is let into the camera, which means the shutter doesn’t have to stay open as long. The most basic way to overcome blur from camera shake is to let in more light by using a large aperture lens.
