The best way to find right crop factor

Category:Uncategorized Tags : 

Before you know how to find right crop factor, you need to know the definion of crop factor. It is common defined as the difference size between a 35mm film frame and your camera’s sensor.

The most common trick to find crop factor is converting the focal length to the full frame equivalent so, you can get the conversion of crop factor you need.

Another way is calculating the diagonal using Phtahgorean Theorem (a² + b² = c²), then divide the number by the diagonal of the crop sensor.

Here is the common focal length and crop factors, by resulting equivalent focal length :

1.5x 1.6x 2.0x 2.7x
14mm 21mm 22.4mm 28mm 37.8mm
18mm 27mm 28.8mm 36mm 48.6mm
24mm 36mm 38.4mm 48mm 64.8mm
35mm 52.5mm 56mm 70mm 94.5mm
50mm 75mm 80mm 100mm 135mm
85mm 127.5mm 136mm 170mm 229.5mm
105mm 157.5mm 168mm 210mm 283.5mm
200mm 300mm 320mm 400mm 540mm

Image Stabilization for sharp images

Category:Uncategorized Tags : 

It is an technology that enable you to capture under lighting conditions so, there is possibility for you to get sharp images. Depending on the make, model, and vintage of your IS-enabled camera or lens, image stabilization allows you to capture sharp pictures at shutter speeds three, four, or five times slower than previously possible.

Lens-based stabilization uses a floating lens element, which is electronically controlled and shifted opposite to any camera shake recorded by the camera.

The worst misconception about stabilization that you can “freeze” fast-moving objects at slower shutter speeds if you have stabilization.

Actually, it only gives you opportunity to take sharp images of static subjects at slower speed. Moving objects will be equally blurry or streaky—and in some cases blurrier or shakier with the IS turned on.

The most important rule for capturing sharp is you shouldn’t handhold a camera at shutter speeds slower than the equivalent focal length of the lens. This means a 500mm lens shouldn’t be handheld at speeds slower than 1/500-second, a 300mm lens slower than 1/300-second, a 50mm lens slower than 1/50-second, and a 20mm lens slower than 1/20-second.

Add image stabilization into the mix and suddenly you can capture sharp images of still objects with a 500mm lens at speeds down to 1/60-second, a 300mm lens at speeds down to 1/30-second, and a 20mm lens at speeds down to 1/2-second.

There are two types of image stabilization (IS): lens based and in camera. In this article, we are only talking about lens based. For deep understanding about stabilization in camera, you can check through this link.

Manufacturers have different name for this function :

  • Nikon – VR
  • Canon – IS
  • Pentax – Image stabilization in the cameras
  • Sony – Image stabilization in the cameras
  • Sigma – OS
  • Tamron – VC

The advantages of in-lens image stabilization include smoother performance when using longer focal length lenses. The downside of lens-based image stabilization is that it’s not available as an option for all lenses and it adds to the cost of the lens. Then again, if you don’t need IS, you often have the option of purchasing a non-IS version of the lens, or at least something similar.

You must keep your tripod away from you when you use image stabilization because if you use it and tripod together so, you will get counterproductive and creating a feedback loop. Here, the camera detects its own vibrations. It will start moving to counteract them, even when the camera is completely still.

And last, you must remember to should turn off your stabilization system is battery life. Having it on, especially when you aren’t using it, will eat up your battery like cake at a kids party. This is especially true of larger lenses and larger sensors. Moving them around requires more energy.

Pick Fixed or Zoom lenses ?

Category:Uncategorized Tags : 

For most, the most suitable choice would be a zoom lens. It has a variable central length. By turning the zoom ring, you move optical components inside the focal point to accomplish an alternate edge of view. This implies you can cause articles to seem bigger by turning the zoom ring one way, or fit more items into the edge by turning it the other way.

You get several focal lengths in the same lens and in consequence you can slip with fewer lenses to meet your needs. Zoom lenses always have two focal lengths specified, for example 18-55 mm, indicating the zoom range of the lens. If you want it to translate into compact camera language, you can just divide the largest number by the smallest, which in the 18–55 mm case gives a zoom of about 3x.

Surprisingly, many beginners often desire monstrous lenses like 70-200mm f/2.8 with image stabilization. Genuine, these focal points are very sharp, have very fast autofocus motors and can survive plenty of abuse. In any case, they are likewise significantly more recognizable because of their sheer size, and their overwhelming weight can cause back and neck torment and even long haul wounds. Most fast, professional zoom lenses, such as 14-24mm, 24-70mm and 70-200mm, have a fixed maximum aperture of f/2.8. In consequnce, they offer not just better light gathering abilities, but also shallow depth of field, which can result in photographs with beautifully rendered background highlights known as “bokeh“. Beside that, this lens has a larger/wider aperture so, it allows you to shoot subjects in low light environments without blur.

Zoom lenses can be great when you need to handle variety of different situations, you can change your lenses when you need to take another view and better result.

This lens has image stabilization, means if you have an f/4 Lens you can get sharp images when you areshooting non-moving subjects in a dark area. Tamron mention the image stabilization as Vibration Compensation (VC).

A fixed lens, on the other hand, has some advantages. Fixed lenses are smaller and lighter and usually have better brightness than zoom lenses. It’s also easier to correct for various lens errors on a fixed lens than on a zoom, so you’re likely to get improved image quality on a fixed lens (although this will vary somewhat based on price and producer).

Some consider it more artistically correct to use a fixed lens and consider using a zoom to be cheating, in a sense, but it’s up to each photographer to decide what works best for them.

Now, you have already known about fixed or zoom lenses. We wish it helps you to pick the best camera lenses for your need and support your creativity.

Focal Length: The main consideration to choose camera lens.

Category:Uncategorized Tags : 

Focal length is one of the consideration components to choose camera lenses mentioned at the previous article. Now, we will talk about it in detail. But, if you do not read the previous article, short tips : What lenses do I need for ? yet, you should read first to get the complete considerations before go to the other consideration tips.

Focal Length has millimeters and specifies whether the lens is a wide angle or telephoto. (Point of view is a lot of the equivalent however considers the sensor size.) We regularly express central length as a 35mm film camera proportionate so, we can comprehend the general edge of view for any camera. After measurement, focal points under 24mm are ultra-wide edge (or fish-eye, if there's noteworthy contortion), wide are between 24-35mm, standard are 35mm to 70mm and zooming focal points come in over that. Large scale focal points, which catch close subjects, are ordinarily in the 35-100mm territory.

With a zooming focal point, you'll normally draw nearer to subjects far away. Zooming focal points are additionally favored for picture as they secure the facial extents superior to a wide edge. With a zooming focal point, it's a lot simpler to get an obscure foundation since zooming focal points have less profundity of field than wide edge focal points. Zooming focal points for the most part have more often than not bring down splendor and are increasingly powerless against fogginess during the shoot if there is any camera shake. Zooming focal points are typically physically bigger than the wide edge focal point.

Wide point focal points, then again, are fine for nature photography when you need to catch a greater amount of the scene. They're normally great both in brilliance and profundity of field, and are generally physically littler and lighter than zooming focal points. On the adverse side the wide point isn't perfect for capturing individuals, at any rate not in an unadulterated representation setting. A wide point gives an impression of more noteworthy separation between what is close and what is far off, and it can in this way rapidly resemble that model has a greater nose and indented eyes. You're additionally bound to get supposed twisting with a wide edge focal point—the straight lines start to twist into the edges of the picture.

The cross between a wide edge and a zooming focal point is popular as an ordinary focal point. This is a focal point that renders the earth as we witness firsthand (in connection to separation and amplification). In the 135 configuration, an ordinary focal point is 50mm. Everything with a littler central length is leading of a wide edge, while bigger central lengths are called fax. On customary smaller cameras with 3x zoom, the central length for the most part stretches out from 35 mm to 105 mm (as indicated by the 135 arrangement).You should remember that it connects to the size of the camera’s image sensor, their changeable is depend on which camera it is used on. To avoid too much confusion, it’s common to explain the focal length equivalent to the so-called full-frame DSLR camera.

So, you can decide what is focal length you need now. The next part we will talk about the other considerations to choose camera lenses completely.

But, for most photographers, a versatile, wide focal-range zoom will be your best bet. Portrait photographers will want a 50-85mm fixed (prime) lens that best flatters the human face. But, product photographers may consider a macro lens, architectural and landscape photographers need wide-angle zoom or fixed lenses, and wildlife plus sports shooters will be drawn to large, relatively fast telephoto (tele) fixed or zoom lenses. If you shoot a lot in low light, you'll need a fast lens (f/2.8 or lower) with stabilization, and video shooters will need to consider things like focus breathing, manual focus and parfocal qualities (more on those shortly).

The difference of Telephoto and Super Telephoto

Category:Uncategorized Tags : 

Telephoto is defined as lens who has long construction which shorter than their focus length, so the optic center is out of body lens. People can find two types of this lens, they are telephoto zoom and super telephoto. But, actually, they have difference function.

Most telephoto lenses have range from “medium” (with a focal length between 70 and 200mm) all the way up to “super telephoto” (with focal lengths longer than 300mm).

Telephoto can be ideal for photographers who are unable to be close to their subjects, such as sport view, wildlife and fashion show. And If you’ve ever seen a photo where the subject is in focus but the background is blurred and wondered how that effect was achieved, the answer is often with a telephoto lens. This use is especially common in portrait photography. The way to achieve this look is to shoot with a long lens and the widest aperture available. For example, a 70-200mm telephoto lens shot at 200m with an aperture of f/2.8 will isolate your subject against a beautiful, creamy background. This lens can be Excellent at Creating Flattering Portraits. Beside that, this lens also serve an artistic purpose, and are remarkable at creating contrasting focuses between foreground and background.

We note  three great ways to get the most out of your telephoto lens from :

  1. Use a telephoto lens to show accurate scale in your photographs. Unlike a wide-angle lens, which can alter dimensional perspective, a properly-used telephoto lens can represent all components of a photo in their actual sizes.
  2. Use long focal lengths for an exaggerated depth of field; use shorter lengths for balanced sharpness between the foreground and background of your photograph.

Beware of camera shake. While telephoto lenses magnify the best parts of your photography, they equally magnify the worst parts. So be sure your shaky camera technique isn’t exaggerated by a telephoto lens. Get your technique right first, and then start playing with telephoto technology.

How to choose the right macro lens for the short distances photography

Category:Uncategorized Tags : 

Before buy a lenses, you need to understand the each function of camera lens types. Here is some tips for you to choose the right macro lens.

Macro lenses are recognized for permitting extremely close-up photography, regularly called "macro photography," after the lens. A macro lens is any lens succesful of enlarging an object to at least a 1:1 magnification ratio, which describes the dimension relationship between the real-world situation and the size of the picture when measured on the sensor.

Means that when the digicam is placed at the closest focusing distance, the photograph fashioned on the sensor will be the identical size as the subject. For this reason, a 1:1 ratio is additionally referred to as "life size" or "standard".

To achieve this, the lens ought to commonly have a very short minimum focal distance to get the object bodily close to the lens and sensor. This makes macro lenses perfect for close-up images and still-life work. Some can even "switch hit" to produce stunning portraits.

But not all macro lenses focal point 1:1, but nearly all can produce pictures that are 1⁄2 life size (1:2). “Macro Zoom,” on the different hand, grew to become a famous description for zoom lenses that focal point shut but are not—in the strictest sense—truly macro lenses.

Macro lens are surprisingly corrected for optical aberrations that be triumphant when targeted close. And even though they are optimized for macro shooting, aberrations are kept nicely under control even when the lens is targeted all the way out to infinity.

Macro lens with under 50 focal length can be used for photo product because their smallest body on their categories will make you comfort and easy to take shoot from the closest distance. But, if you want to take shoot from the medium distance for plants, animals or insects photo so, you can choose Macro lens with upper 50 or 100 or under 100 focal length.

You know how to choose the right macro lens recently. We provide some types of this product, you can visit our product web, we provide some types of this lens for you.
