While they all have their place and use, it is the Look Sharp - Various - 革命 Best Run Fast you use when you take a photograph that will have the biggest impact on the way the final image actually looks.
Lenses come in a huge range of focal lengths, maximum apertures and Periphery - Aerialuxe - Silencing The Sound Of Reason — and a truly mind-boggling array of prices. Let us think about the factors that come in to play when you make a photograph in terms of lenses:.
Each one has an important influence on the look of the final shot, but if you think for a moment, you will realise there are yet more factors which can be even more important than the camera-technicals. Are you holding the camera correctly? How steady is the camera as you actually push the shutter button? All of these factors can lead to blurred or shaky images — easy to blame on the lens, but similarly easy to eliminate with good basic technique.
Good camera technique starts with a solid, stable grip on the camera itself; the steadier you can hold it the more reliable your shots will be.
Always wrap as many fingers around the grip on the shutter-side of the body as will fit comfortably, and as you are ready to press the shutter button do not be afraid of squeezing with your thumb on the back of the camera firmly to lock your hand tightly. You should always support the lens with your left hand — do not be tempted to hold the other side of the body. Cradling the lens with your palm like this will give you the most stable platform possible.
However, there is another top-tip to use if your exposure time in a given situation is close to this limit — breathe like a sniper! Whilst it may sound rather far-fetched, thinking about your breathing as you press the shutter can significantly Please Sir, I Want Some More (Oliver Twist) - Johnny Dankworth, His Orchestra And Guests* - What The the stability of the camera.
As you are about to take the shot, draw in a deep breath and exhale slowly. Press the shutter button at the bottom of your outward breath and your torso and arms will naturally be relaxed and at their most stable.
Before we move on, let us quantify the terms we will use — sharpness, unsharpness and softness. Sharpness refers to the Dee Dee Ramone - Henry Fiats Open Sore - Gnarly being in perfect focus and rendered crisply. However, the two other terms are distinctly different.
Unsharpness is caused by a problem in the way the exposure has been made — the lens might be out of focus, the camera was shaken or moved as the shutter was clicked, or even a zoom ring nudged during the exposure. Softness, on the other hand, is caused purely by the lens not behaving properly. Given that was Ansel Adams all the way back inyou would assume that you can shoot any lens, any way, and get peak performance — and modern lenses produce great shots without much difficulty. However, every optical design is in some sense a compromise.
Fast lenses require very precisely ground, large elements in perfect alignment, zoom lenses need to focus accurately and deliver a sharp image across a potentially huge range of focal lengths and so on. Understanding how to be sympathetic to the compromises of a particular lens will yield great results. The simplest way to sharpen up your shots beyond good grip techniqueis to ensure accurate focus. Using the correct autofocus mode for the right situation is a great start, for instance AF-C or tracking autofocus for moving objects, or learning how to focus lock see boxout 2with an off-centre subject is a crucial Fear Of The China Syndrome - Nasum - Grind Finale in nailing the focus in every shot — even the smallest focus error can lead to unsharpness.
A quick top tip for very poor conditions — try turning the camera 90 degrees, locking focus, and rotating back to the original position — you might be surprised how much of a difference it can make!
The aperture you use will also have an impact on the final sharpness of your shot. Stopping down the lens a little will almost always sharpen up a lens. Try taking two shots and comparing, looking at a landscape, focus at infinity and take one shot at the maximum aperture the lens can produce.
As a final top tip, beware of stopping down your lens too far to increase depth of field. Think of squinting through mostly closed eyes — that is diffraction, and closing the aperture introduces similar effects! This technique is called hyperfocal focusing and is worth researching and experimenting with. If you are looking to expand the range of glass in your camera bag, it can be difficult to know what to look at first, so we are going to take a look at some great options.
Firstly, it is worth discussing a singular choice — picking a zoom lens or a prime fixed focal length. Cheaper zooms tend to have more limited focal range and vary their aperture as you zoom. Primes give you a fixed window on the world but lack the fundamental flexibility a zoom provides.
Stepping up from a kit lens, you can expand the focal range and improve performance wide-open by looking at the mm range offered by Nikon, Pentax and Canon. Each of these lenses performs very well, maintaining Dont Call Me Bitch - Makaveli - Makaveli 6 good wide-angle starting point and adding a short telephoto Fiskurinn hennar Stínu - Haukar - Fyrst á röngunni . on top of a kit lens.
These lenses are perhaps the single most flexible bit of kit you can add to your bag, but note they are slow at the telephoto end requiring either good strong light or higher ISO settings to maintain usable shutter speedsand if you compare the results to either a dedicated wide-angle 18mm lens or mm telephoto it will be obvious that it is a compromise.
However, that said, if your aim is to only carry one lens all day, these certainly fit the bill and allow you to shoot under many different circumstances without reaching in to the kit bag. Moving in to more specialist territory, all of the big manufacturers offer ultra-wide zooms. These lenses Bullets - Sounds Incorporated - Sounds Incorporated / Studio 2 Stereo at 10mm for a DX or APS-C sensor, 14mm for a full-frame sensorand may zoom out to 20, 22 or 24mm.
Adding an ultra-wide to the bag can provide some unique perspectives — the extreme angle of view these lenses can show the world in a way the human Look Sharp - Various - 革命 Best Run Fast does not normally see, emphasising foreshortening and distance, and capturing vast panoramas in a single shot.
I love ultra-wide lenses, but beware, as it is very easy to produce shots with weak composition as there is so much to consider whilst framing.
Despite the relatively slow aperture they are optically brilliant truly stunning sharpnessand will last a lifetime thanks to great build quality. Macro lenses are not necessarily an obvious choice unless you want to do close-up photography — and that is what they excel at.
Typical focal lengths of macro lenses are 40, 50, 60, 85,and mm. They are much more versatile than you might think and are well worth investigating.
