Things to consider before buying the best Canon Lens For Astrophotography
Light gathering ability of the lens
Before you start planning your night photography, look at the lens specifications to see how much light it can gather. This is important because you’ll be shooting at night, when light is scarce. One of the main lens specifications for this is something called its “f-stop” or aperture range. Aperture refers to the size of a lens opening that allows light to pass through and reach the camera sensor or film.
An f-stop may also be referred to as an f/number or focal ratio, where f stands for focal length (measured in millimeters). As an example, a 50mm lens has a focal ratio of f/1.4 if its aperture openings are 70mm (50 x 1.4 = 70) in diameter. In general, higher numbers such as f/8 mean that the aperture openings are smaller and less light will pass through; lower numbers such as f/1.4 mean that the aperture openings are larger and more light will pass through.
The speed of the lens
Choosing a lens for astrophotography comes down to the speed of the lens. The fastest aperture you can find is ideal. A fast lens has a large aperture that can let in more light, which is important when taking photos at night.
The speed of a lens is measured using f-stops, and it describes its maximum aperture size. The smaller the number, the larger the aperture opening and thus this means faster.
For example, a Canon EF 50mm f/1.2 L USM Lens is faster than Canon EF 50mm f/1.8 STM Lens because f/1.2 opening is larger than f/1.8 opening (i.e., 1 / 1.2 = 0.83 vs 1 / 1.8 = 0 .56). Therefore, if you would like to take pictures of stars at night with your camera on a tripod, slower lenses are not recommended as they have slower maximum aperture (f-stop) values and will require longer exposures resulting in star trails even when you use lower ISO value which increases noise levels in your images.
Size and Weight of the Lens
The size and weight of your lens can be a significant factor in how and when you use it. If you are travelling and need to carry your gear around then a lens that is light and small will be a priority.
On the other hand, if you are shooting from home or have someone to help out with carrying then the difference between sizes might not matter that much. The end result is going to heavily depend on what kind of shots you want to capture and your own personal preferences.
Focal length and cost
Your choice of lens will be determined by the focal length. The focal length is determined by the size of your camera sensor. The focal length refers to the ratio between the distance of your camera sensor and the point at which light rays converge into focus after passing through a lens. A shorter focal length means that you can see a wider view, while a longer focal length allows you to zoom in closer to whatever it is you’re shooting.
A telephoto lens has a longer focal length and allows you to get close-up shots of distant objects without moving closer yourself, while a wide-angle lens has a short focal length, so it captures a wide view of what’s in front of it. The cost of your Canon Lens For Astrophotography is also affected by its weight, which depends on the size of your sensor and the speed with which it focuses on an object or person’s face.
Focusing Distance and Focus Limit Switch
The focus distance is the minimum distance between the lens and the subject for accurate focusing. This distance varies from lens to lens. The closer subjects can be focused, the higher their magnification will be. The more distant subjects can be focused, the larger your field of view will be.
The closer you can focus a lens, the higher its magnification will be-both for close-ups of stationary subjects and for maintaining a consistent image size of moving subjects when focusing on them as they approach or recede from you.
At very close distances, however, depth of field becomes so shallow that it may become difficult to get a large enough area in sharp focus to remain pleasing. This effect can sometimes be used creatively (for example, by blurring out or obscuring elements that might otherwise have distracted from your main subject), but it’s an effect worth keeping in mind when choosing optics based upon their minimum focus distance capabilities.
Some lenses also include a focus limit switch that enables you to limit the range over which they will hunt to achieve focus: For example, instead of searching through their entire range before locking onto either a near or distant target (each requiring different amounts of time for different lenses), this switch enables them to ignore targets outside their selected range and thus lock onto targets inside that range faster than they would have been able to had they needed to search throughout their entire focusing range first. The shorter the focusing range in which such lenses are limited when using this feature,the faster they will lock into place.
Image stabilization is an important feature of the best Canon lens for astrophotography. The image stabilization reduces the effects caused by camera shake and also helps improve the quality of your photos.
In order to get a good image, it is important to use a lens with good image stabilization. There are many lenses available with this feature, but you need to choose carefully in order to get a good one.
Filters And Filter Threads
When you are going to buy a lens, you need to check the filter threads of the lens. It is so because it will help you for attaching a filter with the lens. A camera filter is nothing but a glass or plastic disc. It helps photographers for controlling different light effects in their pictures. Apart from this, it is also used for reducing UV rays and protecting lenses from dust, dirt and moisture etc.
The filters work either by altering wavelengths of light that reach the sensor area or by changing the way focal plane sensor emits light. In this way, they are able to improve color in your images and remove unwanted reflections in your photography etc.
Various types of filters you can find in the market—UV, ND and polarizing filters etc. You can use these filters according to your specific requirements if shooting landscapes then you can use ND or polarizer filters etc.
