How to select Your First Dslr Lens - A Newbie Guide

When it comes to dslr photography sometimes things can get a slight complicated, this is especially true when it comes to manufacture the first buy after your kit lens. Do you choose a zoom lens, a wide angle lens, a prime lens or even a fixed aperture lens? Well don't worry yourself to much because this report is here to help you.

[b]Lens[/b]

Zoom Vs Prime

A zoom lens will allow the photographer to zoom which isn't to surprising. The advantage of a zoom lens is the ability to zoom in and out on your subject to originate the perfect composition. Zoom lenses are favoured by most photographers because of this function, however zoom lenses usually have higher f-stops than prime lenses, and this means that they usually leave less light into a photo which will affect the shutter speed being used.

A prime lens on the other hand doesn't allow you to zoom at all, your slight to one focal length. You may think this sounds rubbish, however there are many advantages to using a prime lens over a zoom. First of all prime lenses usually have lower aperture values and some of them go right down to f1.2 this means that a lot of light can enter the camera lens this is especially beneficial for low light situations.

Fixed aperture or non fixed

The f stop numbers were briefly discussed above, but just in case you didn't understand let me expound in a slight more detail. The lower the F-stop the more light can get into your camera while the higher the f stop the least number of light can enter, both ranges have their uses.

Some lenses for example the canon 70-200mm 2.8 has a fixed value of 2.8 through its whole zoom range, this means that a constant aperture can be achieved through out. This is very beneficial when shooting studio photography for the uncomplicated reason that the aperture controls the power of the flash, if the aperture of the lens was to turn for example the canon 18-55mm 3.5 to 5.6 then the force of the flash would enduringly turn giving you inconsistent results. If you can afford a lens with a constant aperture get it.

Image Stabilisation

Some lenses and some camera bodies such as the Sony Alpha A350 have built in image stabilisation. Image stabilisation allows you to a distinct degree to shoot at lower shutter speeds without motion blur. Image Stabilisation is beneficial in distinct situations but it can also be a waste of money. If your shooting fast fascinating images then chances are you won't need image stabilisation, the same applies if you use a tripod.

Different focal lengths

There are also focal lengths that you will need to take into account when purchasing a new lens. If you shoot nightclub photography or wildlife photography then chances are you will need something wider than 50mm. So below I will expound the best type of lens for distinct situations.

Wide angle lenses

As discussed above wide angle lenses are mostly used for landscape photography but they can also be used for nightclub photography where there's not too much room to move around. If money is no object then the Canon 16-35mm 2.8 lens is an perfect selection which retails for colse to £1200. however if money is an object then the Tamron 17-50mm 2.8 lens is an perfect alternative. The Tamron lacks the build ability of the canon and also the autofocus speed, however I personally own this lens and the image ability is excellent. The Tamron can be picked up online for colse to £300-£400.

Medium Range lenses

A medium range is not too short and not too long; it's in the middle, hence the name medium. Medium range lenses are perfect for portraits, model shoots and even wedding photography. The best lens in this range is the Canon 24-70 2.8 which is a favourite lens among many expert photographers. The canon 24-70 is an perfect lens that has an perfect build quality, however the lens is very heavy and is very expensive, however if your reasoning of shooting weddings then this is a must have bit of kit.

An perfect alternative is the sigma 24-70 2.8. The sigma offers the same focal length while being a lot cheaper. The image ability one again on the sigma is excellent, however some owners have experienced focusing problems, this can be fixed by sigma but it is worth mentioning just in case you do get this lens.

Telephoto Zooms

If you're seeing to shoot wildlife, sports or even glamour photography then a telephoto lens is something you will want to invest in. Ordinarily these types of lenses are very high-priced but when we are talking about photography most things are. If money is no object then you will want to get the canon 70-200mm 2.8 telephoto lens.

The canon 70-200 2.8 is an high-priced lens used by most pro photographers, it offers an impressive autofocus ideas and perfect build ability but once again this lens is pretty heavy. If you don't need the quickness of the 2.8 then you could go for the canon 70-200mm f4 lens. This lens isn't as heavy and creates sharper images in my opinion than the 2.8.

If both of the above lenses are too high-priced then a good alternative is the sigma 70-200 2.8 lens, it's a fast lens with perfect image ability and is more affordable than the above two lenses.

Other lenses

There are many other types of lenses which contain macro, tilt and shift, fish eye and many more; however as a beginner you will more than likely only be interested in the lens types mentioned above.

Choosing your lens

Overall selecting a lens doesn't have to be a difficult experience. To help you choose naturally think of what you will be using your camera for, will it be for wildlife pictures, sports, portraits or even close up photography, and this can then help you choose the required lens. If you can afford a fixed aperture lens then go for it, I would also suggest getting the lowest aperture that you can afford, not only will this leave in more light but it will also give your images the blurry background result that you see on most expert photographs.

select the Right Lens for Portraits

There is nothing that beats a good portrait photograph. Especially when both the field and the photographer are pleased with the results.

[b]Lens[/b]

But, if you want to take good portrait photos you need to think about investing in the right sort of lens. If you want your subjects to be pleased with the results of your work, then make sure you get a lens fit for the job. And that means, one with the literal, focal length.

Lenses with a focal length less than 80mm are no good. They make noses look too big because the photographer has to get in too close. The ideal portrait lens has a focal length in the range 90mm to 135mm. These keep the natural proportions of the face as you see with the naked eye.

Don't forget your sensor size when determining the equivalent focal length. Most contemporary digital cameras have a sensor that is smaller than the 35mm film equivalent. This means you have to factor in a multiplier to get the literal, lens focal length. A film lens of 50mm would work out 80mm on a digital sensor with a 1.6 multiplier factor. Refer to your camera handbook for information on magnification factors for sensors.

A longer focal length means you can stand a bit additional away and still fill the frame to your desire. This makes the nose more in proportion with the rest of the face and is very flattering.

How to select the Best Color taste Lenses

Decided to convert your eye color with colored contacts and don't know which ones to choose? Find out what the color contacts store has to offer and which lenses will make your eyes look most remarkable and beautiful.

[b]Lens[/b]

Color taste lens types

You can get disposable (1 day, 2 weeks or 1 month transfer schedule) color taste lenses as well as primary (annual replacement) lenses. Each type has its advantages and disadvantages.

Disposable lenses are healthier for your eyes. First, they are thinner so the lens lets more oxygen through to your cornea. Second, protein build-ups are less of a qoute with disposable taste lenses - it doesn't have sufficient time to build up. And third, if you replace your taste lenses often, the risk of bacterial infection is much less. So from the condition point of view, disposable color contacts like Freshlook or Acuvue 2 Colors are better. Disposable color lenses are especially recommended if you want to wear your color contacts every day for longer than 8 hours.

On the other hand, the best each year transfer color taste lenses are hand painted, while all disposable contacts are digitally printed. For a color taste it is very prominent not only to give you a brilliant vibrant color, but also to look natural. If you look very intimately at your eyes, you will see that your iris isn't a solid color but has varied colors and patterns. Some habitancy have a starburst pattern, while others have tiny rays of yellow or black in a blue or green iris. These patterns and colors give your eyes a feeling of depth. Hand painted lenses, like Durasoft 2, contain subtle details and varied colors. This helps to simulate depth and gives your eyes a very natural appearance.

As you can imagine, hand-painted color contacts are more difficult to produce, so they are more expensive. This is literally the reason they don't come as monthly disposables - very few habitancy would pay 50 dollars or more for color contacts that only last a month!

Best color contacts for dark eyes

If you eyes are dark brown, blue or green your only selection is opaque taste lenses.
Enhancement color lenses will only disappoint you.

The best options for dark eyes are:

• Freshlook Colorblends - opaque, monthly disposable lenses with bright, brilliant color and natural seeing patterns. The most popular shades are Amethyst, Blue Sapphire and Green
• Acuvue 2 Colors Opaque - 2 week disposable color lenses that create soft seeing color
• Durasoft 2 and Durasoft 3 Opaques - strikingly bright, yet natural looking, color. Durasoft is a hand-painted each year transfer taste lens. Durasoft 3 looks best, but it is expensive
• Illusions - also each year replacement, hand-painted color contacts. For a soft, light color chose Soft Green of Soft Blue. If you want a remarkable color, go for Violet, Deep Blue or Deep Green

If your eyes and skin are dark, be rigorous not to get a color that is very light. Light green or blue eyes won't look natural with bronze skin. Instead go for deep blue, green or amethyst.

Best color contacts for light eyes

If your eyes are light, you can wear both opaque and enhancer color taste lenses. To convert your color pick opaque contacts, because green enhancers over blue eyes, or vice versa, can give unpredictable result.

Recommended color contacts for light eyes:

• Freshlook Dimensions - monthly disposable contacts that don't convert your natural color, but add depth and make your eyes appear larger
• Freshlook radiance - also monthly disposables, which make your eyes appear challenging and sparkling. radiance comes in Eden, Moonlight, Sunrise and Autumn. The radiance consequent is literally striking.
• Durasoft 2 for light eyes - each year transfer color lenses. The lens looks very natural because of the determined painted pattern and blend of colors. You can get Aquamarine, Sky Blue, Jade Green, Violet Blue
• Illusions Soft Blue and Soft Green - opaque each year transfer color lenses that create beautiful, very light, natural seeing color.

People with very light eyes should be particularly careful. Some enhancement color contacts tend to make light eyes look darker. The explication here can be quite unusual - go for opaque lenses that simulate light color, rather than enhancers. Soft Green or Soft Blue Illusions can be a good choice.

If you feel like you want to convert something in your appearance, trying color taste lenses is a good choice. Get yourself a pair of brilliant color contacts and enjoy watching heads turn as you pass.

Diopter 101 - How to select Your Reading Glasses' drive

Since the Middle Ages, civilizations utilized lenses, even without fully insight the science of optics.  In fact, people in the Middle Ages learned to use framed lenses to fetch best vision. 

[b]Lens[/b]

Today, many people understand the relationship between lenses and light refraction.  But it wasn't until the 17th century, and the work of the scientist Willebrord Snell, that the phenomenon of light refraction became a scientific law.  Einstein and other scientists refined theories about light, and only in the latter part of the 20th century have optical systems been well understood.

Your foresight and diopter impel

The human eyes bend light, allowing people to see. But when the eye's light bending power is no longer enough to provide clear vision, the light refracting attributes of lenses are used to augment the declining optical power of the human eye. But how much light refraction is needed to compensate for decreasing vision?  

The light bending ability of the lens is based on its focal length.  If the focal distance is shorter, then the lens has a greater ability to bend light. And if the focal distance is longer, then less light is refracted by the lens.  For people buying reading glasses, the focal distance of the lens is important.  For a lens that has a focal distance of 1 meter (about 40 inches), its optical power is reported as 1 diopter. The term "diopter" is the unit for optical power, just as "meter" is the unit for distance.

The median human eye has an optical power of 40 diopters (about 1.574 inches or 131 feet).  The human eye is a sophisticated optical system that can instinctively adjust its focus by 20 diopters nearer and farther. This ability of the human eye to adjust its focus is known as "accommodation."

Unfortunately, despite the sophistication of the human eye, its "accommodation" abilities may deteriorate over time. A severe deterioration of the eye's room is a health known as presbyopia. A man who is 25 years old and older can ordinarily adapt only by 10 diopters. And a man who is 50 years old and older can ordinarily adapt only by 1 diopter. To offset the deteriorating optical power and still have clear vision, people use reading glasses.

How to reckon the right diopter impel for your reading glasses

Reading glasses refract light in a manner that enables a user to see clearly.

Remember, the optical power of reading glasses are also expressed as diopters. If a definite pair of reading glasses has a diopter of 2.00, it means that the lenses can refract light to focus on objects that are ½ meter (about 20 inches) away. If the diopter impel is 3.00, the lenses can refract light and focus on objects that are 1/3 meter (about 1 foot) away. The higher the value of the diopter strength, the closer the focus of the lens. 

The eye's ability to adapt typically deteriorates gradually. That means the eye will wish reading glasses with lenses of dissimilar strengths over time. To meet the needs of the human eye, the optical power of reading glasses' lenses vary in small increments. The diopter strengths can be 1.00, 1.22, 1.50, 1.75, and so on, up to 3.00.  people in their 40s ordinarily need reading glasses with a diopter impel of 1.25. And people in their 50s use a diopter impel of 2.25 and higher for their reading glasses.

To rule which diopter impel is best for you, you can test your eyes by using the chart found by clicking here:  Reading Glasses Eye Test. Print the chart and read each line. When you have reached the line where you can no longer see clearly, you have found the diopter impel you need.

How to select the Best Canon Portrait Lens

Before getting into the seminar of which lens is the absolute best Canon portrait lens, here is something to think and take some pride in.

[b]Lens[/b]

Have you noticed that when you are carrying that Canon digital Slr camera, you normally are noticed because most folks know the value of the tool you hold in your hands? Even though they may know nothing about how to use it, they are in awe of its capabilities.

That's why a majority of photographers, even the ones that are not dedicated portrait photographers, are asked to take portraits of friends and family all the time. Population assume that you are a great portrait shooter because of the Canon you shoot with.

Go ahead and let them think it. Then fire away. But first, read below to get the skinny on what makes a digital lens a portrait lens.

In an effort to discover the best Canon portrait lens, you will find an substantial variety of opinions about which one is the absolute best. And while it is sometimes a function of how much money you spend on a lens, it is more often about how you deal with the setup, the lighting, and the subject.

Yes, the lens you pick is important, and here are some things you will want to know if you are choosing a portrait lens for your Canon digital slr.

First, the portrait lens is not just about focal length. It is about perspective too.

You will normally be taking a original portrait that includes head and shoulders, and you want it to look general to the viewers. That means you don't want facial parts to look distorted or out of proportion.

Normal distance from your branch to achieve a general perspective is about 10 feet. You can achieve this with a lens that is in the middle of 75mm and 150mm. If your camera is a "crop" sensor, you can use less focal distance because the camera will capture photos as if it were a longer lens. An example is a Canon Rebel with a 50mm lens will act like a full frame camera with an 80mm lens, taking into consideration the 1.6x sensor.

You can get the same image with a 22mm lens as you can from an 85mm lens if you are closer to the subject. However, there is a very real possibility of having a distortion of facial parts because you will be so close to your subject.

For that reason, the best Canon portrait lens is at least 85mm.

On the other hand, you don't surely want to use a telephoto lens that is, say, 400mm, naturally because you would have to be too far away. Yes, you could get a good shot than the 22mm example, but the distance from the branch being somewhere nearby 30 ft is not optimal for communicating with your subject.

That's why the best Canon portrait lens option would also be 150mm or less at the long end.

Aperture is also a very important aspect of a good lens. The wider the aperture, the better. Recommended gap ,break would be f/4 or less, preferably f/2.8. The large gap ,break will give you that nice, soft background that is so desirable in Population photos. It is ended by the shallow depth of field that happens when a wide gap ,break is employed.

There are some surely great lenses that fit these requirements. Is there one that is good than all the rest. Many pros would have a specific lens to recommend, but the truth is, there are any that fit the bill.

The key is, what is the best Canon portrait lens for You. Will you be using it exclusively for portrait photography, or will the lens duplicate up for other types of shots as well.

The man (or woman) behind the camera is just as important as the lens in front of the camera when it comes to getting the best shot. Know how to use the settings, the light, and the subject.
