There are wider angle APS-C lenses available, but these have a much smaller image circle producing a much narrower angle of view and are essentially incompatible with full frame cameras. (the-digital-picture.com)
To say that a 16mm max-wide lens owner will be very impressed by the 11mm angle of view is an understatement. (the-digital-picture.com)
However, there remains a position to be filled in the APS-C wide angle lineup and that is for a lens with stand-out image quality. (the-digital-picture.com)
It means when the lens is not zoomed it has an angle of view of 18mm (very wide angle of view that fits more of the scene than what you see with your eyes). (phototacopodcast.com)
When you turn the zoom ring on the lens it will zoom into the scene to a maximum of 55mm (an angle a view that is "zoomed" in more than what you see with your eyes). (phototacopodcast.com)

The 3.5 and the 5.6 are referring to the maximum aperture the lens can achieve for each end of the zoom range. (omnilargess.com)
However if you zoom in for a tighter shot the maximum aperture will change to f5.6, which means the image will be underexposed by 1 stop. (omnilargess.com)
To recap: some zoom lenses on digital SLR and compact digital cameras often list a range of maximum apertures, relative to how far one has zoomed in or out. (omnilargess.com)
These aperture ranges refer only to the range of maximum aperture, not overall range. (omnilargess.com)
Canon lenses, such as the 24-70mm f/2.8, are designed for maximum versatility and image quality. (smallbiztrends.com)

The 7-blade circular design keeps the aperture almost perfectly circular throughout the full range of F-stops. (sony.com)

Adjusting the size of the opening for your lens based on environmental conditions will help achieve the exposure you want. (adobe.com)
It also excels in video recording performance with a mechanism that suppresses focus breathing and includes a micro-step aperture control for smooth exposure change. (panasonic.com)
As long as you shoot at 70mm where the lens allows f4.5 you'll get the correct exposure. (omnilargess.com)

You may see something like "18-55mm 1:3.5-5.6" written on the front or side of the lens. (phototacopodcast.com)
If you are shopping online and looking at buying a lens then you will probably see a description more like "18-55mm f/3.5-5.6" which should now make a lot more sense to you of what that means. (phototacopodcast.com)

With an optical system that rivals that of interchangeable lenses for full-size SLRs, the lens features a wide variety of high-tech optical elements. (photoxels.com)
This lens effectively minimizes optical aberrations and offers superb resolution at wide-open aperture and throughout the aperture range. (photoxels.com)
POWER O.I.S. is a versatile lens ideal for virtually any shooting situation thanks to its large aperture, O.I.S. (Optical Image Stabilizer) integration, compact size, and lightweight profile. (panasonic.com)
While this is a wonderful advantage to have, there are optical limitations that should be understood when choosing a zoom lens. (omnilargess.com)
These aspheric lenses can also be used to replace multiple spherical elements in optical assemblies to reduce weight and cost. (edmundoptics.com.sg)
Its solid build, focus, optical performance, and zooming function have been lauded by quite a few reviewers who have created masterpieces with this lens. (digitalcamera-hq.com)
This more compact version of the CP.2 lens features optical dimensions and characteristics that go one step further in terms of quality, improved mechanics, and better lens coating, of course, in a smaller frame. (look3.org)
While on a general note, there is no optical disadvantage to using cinema lenses for normal photography, the lenses would always perform better in cinematic shootings. (look3.org)

Refractive phase plates acting as glasses for X-ray optics have been fabricated, and spherical aberration in refractive X-ray lenses made from beryllium has been successfully corrected. (lu.se)

The marketing for the new lens also emphasizes its superior peripheral illumination. (videomaker.com)

Looking for a lens with a versatile zoom range and original design? (6ave.com)
Aperture adjustments affect the depth of field for your photos - the range between the nearest and farthest objects in focus within a picture. (adobe.com)
Some higher-end lenses can maintain the largest aperture throughout the entire zoom range, so only one number is detailed. (omnilargess.com)

This lens is a redesigned replacement for the LUMIX G X VARIO 12-35 mm / F2.8 II ASPH. (panasonic.com)

As such, these lenses are generally more expensive than variable aperture zooms. (omnilargess.com)
Zooms of cine lenses are designed to suppress issues of focus shifts as well as off-axis changes, and a very good cine lens would perform excellently well here. (look3.org)

This should make the lens good for low light usage and deliver a very shallow depth of field. (videomaker.com)
The lens also features the Nikon Meso Amorphous Coat to prevent reflections regardless of the direction from which light enters the lens. (videomaker.com)
Smaller apertures let in less light, so naturally, larger apertures let in more light. (adobe.com)
By using the widest aperture your lens allows, more light will enter through your lens. (digital-photography-school.com)
This is a wide aperture because the hole is really big, lets lots of light in. (skillshare.com)
With these very inexpensive lenses that are variable aperture they do fine when there is plenty of light like shooting outdoors while the sun is out but they don't have a wide enough aperture to let in enough light to do well with night or indoor photos. (phototacopodcast.com)
With this lens, you also get four stops of image stabilization to help when shooting in low-light conditions. (popphoto.com)
The two photos below were both taken with a Nikon D200 using an aperture of f/8.0 in less than perfect light. (runeberg.org)
Light is further converged by the crystalline lens located posterior to the iris. (medscape.com)
By changing its shape, the lens focuses light onto the retina. (msdmanuals.com)

Shallow depth of field , which blurs the background to help pop the in-focus subject of the photo, is achieved with a wide aperture. (adobe.com)
Because these super large aperture lenses offer a way of viewing, an extreme shallow depth of field that the human eyes do not have. (viltroxstore.com)

Aphakia, the absence of the crystalline lens, may occur as a result of trauma, lens subluxation or dislocation, or surgical management of a visually significant cataract. (medscape.com)
The aqueous humor accumulates around and behind the crystalline lens leading to lens-iris contact and the obstruction of anterior aqueous movement. (medscape.com)

The trend amongst some lens manufacturers lately has been to support rear "gel" filters. (diyphotography.net)
Putting filters behind the lens instead of in front of it means that you can go much thinner with the glass. (diyphotography.net)
It's become a popular way to attach filters for those lenses that support them. (diyphotography.net)
The filters are then able to quickly be attached to the rear of the lens using magnets and removed just as quickly when done. (diyphotography.net)
I'm going to tell you all about lenses, tripods, remote triggers, neutral density filters. (skillshare.com)

This lens is constructed with 16 elements in 14 groups. (videomaker.com)
The hybrid lens will reportedly feature a single glass element and six plastic elements. (inferse.com)
It takes larger lenses and glass elements to allow the lens to have a constant aperture throughout. (phototacopodcast.com)
Super Integrated Coating has been applied to lens elements to minimize surface and internal reflections for a marked reduction in lens flare and ghosting. (eamobitech.com)
