He used it quite effectively above.  Heck, I am more of a super-telephoto guy. I wouldn&#8217;t mind having one in my bag at Bosque or in the Palouse&#8230;.<\/p>\n<p>The 11-15 is a truly versatile wide-angle zoom lens featuring an advanced optical design and constant f\/4 maximum aperture, the Canon EF 11-24mm f\/4L USM Lens is a member of the esteemed L-series of lenses designed for full-frame EOS DSLRs. One Super UD element and one UD element offer a significant reduction in chromatic aberrations while four aspherical elements help to minimize distortions throughout the zoom range and provide consistent edge-to-edge sharpness and illumination. Both SWC and ASC coatings have been applied to the elements in order to reduce lens flare and ghosting for increased contrast and color accuracy. Ideally suited for landscape and architectural photography, this lens covers ultra-wide to wide-angle perspectives and backs up its versatile zoom range with sophisticated optical components and intuitive handling.<\/p>\n<p>In regard to focusing performance, a ring-type Ultrasonic Motor offers fast, smooth, and near-silent autofocus, which is further benefitted by full-time manual focus operation and an internal focusing design. The lens is both water and dust-resistant, and fluorine coatings have also been applied to the front and rear elements to protect against fingerprints and smudges from affecting image quality.  It is compatible with full-frame EOS DSLRs, as well as with APS-C-sized sensors (like the EOS 7D Mark II) where it will provide a 17.6-38.4mm equivalent focal length range.<\/p>\n<ul>\n<li>Constant f\/4 maximum aperture offers consistent performance and light transmission throughout the zoom range.<\/li>\n<li>One Super UD (Ultra Low Dispersion) and one UD element help to significantly reduce chromatic aberrations for improved clarity and color accuracy.<\/li>\n<li>Four aspherical elements help to minimize distortions throughout the zoom range in order to maintain edge-to-edge sharpness and illumination.<\/li>\n<li>Both a Subwavelength Coating (SWC) and an Air Sphere Coating (ASC) have been applied to lens elements to reduce backlit flaring and ghosting for maintained light transmission and high contrast in strong lighting conditions.<\/li>\n<li>A ring-type Ultrasonic Motor (USM), along with an internal focusing system, high-speed CPU, and optimized AF algorithms, are employed to deliver fast, precise, and near-silent autofocus performance.<\/li>\n<li>Full-time manual focus operation is available for fine-tuning of your focus position when working in the AF mode.<\/li>\n<li>A weather-resistant design protects the lens from dust and moisture to enable its use in inclement conditions.

There was very little light.  I was fighting for shutter speed.  I wanted to avoid raising the ISO.  There was only one choice as far as the aperture: f\/2.8. And I never worry about depth-of-field when doing flight photography&#8230;. In the blog post <a href=\"https:\/\/www.birdsasart-blog.com\/baa\/2015\/04\/13\/wide-open-for-flightbw-layer-mask-tip-nik-silver-efex-pro-2-osprey\/\">here<\/a>, &#8220;Wide Open for Flight,&#8221; I explained why I often go &#8220;wide open for flight.&#8221;   As it seems that that lesson needs to be repeated, that is what I will do here \ud83d\ude42<\/p>\n<h2><strong>Why Wide Open for Flight?<\/strong><\/h2>\n<p>Most of the time when doing flight photography I will work wide open or close to it. Here, I went wide open to the max at f\/2.8. To my eye, the depth-of-field is more than sufficient to cover the whole bird from wingtip to wingtip.<\/p>\n<p>Here are the reasons in no particular order that I work wide open or close to it when doing flight photography:<\/p>\n<p>1: The wider the aperture at a given ISO the faster the shutter speed. Fast shutter speeds are ideal for flight photography. My good friend Ned Harris, a skilled and oft-published hawks in flight photographer, once said to me, \u201cIf I could work at 1\/8000 sec. all the time for flight photography I would do just that.\u201d<\/p>\n<p>2: Working at the widest aperture will always let you use the lowest ISO for a given shutter speed (always assuming that you are exposing to the right\u2013as I did here in an extreme low-light situation\u2013in order to come up with a good exposure).<\/p>\n<p>3-In most flight photography situations the birds are far enough away to ensure sufficient depth-of-field to cover the entire bird. Remember that as camera to subject distance increases, depth-of-field increases. For me, the myth of stopping down either one full stop or always working at f\/8 is pretty much bad advice. A secondary factor here that bolsters my argument is that though you would typically want more depth-of-field when working close to a lens\u2019s minimum focusing distance, depth of field at close range is minimized\u2026. In other words, stopping down in these situations will not help you much anyway\u2026.<\/p>\n<h3>Simply Put<\/h3>\n<p>With most bird photography, the wide apertures are usually fine.  They pay off with high shutter speeds and lower ISOs.  With birds in flight, you almost always have enough depth-of-field to cover the bird from wingtip to wingtip, even when working at the wide open aperture. And if you do stop down, you do not gain much.  You should stop down when photographing birds at extremely close range, close to the minimum focusing distance of your lens. In those case be to sure focus on the eye or at least on the same plane as the bird&#8217;s eye. <\/p>\n<h3>Facebook<\/h3>\n<p>Be sure to like and follow BAA on Facebook by clicking on the logo link upper right.
