A prime telephoto camera lens like the Canon EF 300mm F/4L is a great way to capture deep-sky astrophotography images, as long as you’ve got a way to track the night sky for each shot. The wide field of view is very forgiving, meaning autoguiding isn’t necessary for a successful long exposure image.
Hereof, Is 2.8 fast enough for astrophotography? Takeaway: Shoot at the widest aperture setting possible, especially if your lens’s maximum aperture is in the range of f/2.8 to f/4. If your lens’s maximum aperture is in the range of f/1.4 to f/2, that advice still holds – but make sure you are comfortable with the amount of coma and vignetting in your images.
Is f4 good for astrophotography? Focusing the lens is a straight forward process at 24mm, and even offers a little forgiveness at an aperture of F/4. Faster lenses that can open up to F/1.8 are beneficial for astrophotography but often result in a challenging focus routine.

What is a 75 300 mm lens used for?
Lightweight telephoto zoom
This 4x telephoto zoom lens is ideal for the budget-conscious photographer with an interest in shooting sports, wildlife or portraiture. In common with other telephoto lenses, the EF 75-300mm f/4-5.6 III compresses perspective and allows the photographer to restrict depth of field.
What is the 500 rule in photography? The 500 rule is used to measure the maximum exposure time you can shoot before the stars become blurry or before star trails appear. Setting the shutter speed for longer than allowed by this rule will result in images that do not have sharp stars.
Is f4 enough for astrophotography? Focusing the lens is a straight forward process at 24mm, and even offers a little forgiveness at an aperture of F/4. Faster lenses that can open up to F/1.8 are beneficial for astrophotography but often result in a challenging focus routine.
Can you use f4 for astrophotography?
What is better f2 or f4?
An f/2.8 lens will give you twice the shutter speed of an f/4 lens when shooting with the aperture wide open. If you find yourself photographing moving people or other moving subjects, where fast shutter speeds are critical, then the f/2.8 is probably the right way to go.
Is a 24mm lens good for astrophotography? 24mm is an ideal focal length for astrophotography applications, particularly nightscape photography. When paired with a full-frame astrophotography camera, the results are simply stunning.
Is 400mm enough for bird photography?
Yes, 400mm is enough for bird photography. Don’t just take our word for it either, have a quick look at the Canon 400mm lens group on Flickr to see an impressive assortment of bird photography images shot at this focal length.
How far can a 300 mm lens zoom? If you’re shooting a full frame camera – the Canon 100-400mm gives similar coverage.
…
First Priority is Focal Length.

Is a 300mm lens good for wildlife?
A 300mm lens is enough for wildlife and bird photography. With a lens of this focal length, you’ll be able to capture detail from a distance, even when focusing on small subjects like songbirds.
Is a 75-300mm lens good for astrophotography?
The Canon EF 75-300mm F/4-5.6 III is a surprisingly good lens for astrophotography considering the price. With the right approach, it can produce sharp, flat images of deep space objects in the night sky.
How far away can a 70-300mm lens shoot? The bottom line – on a crop frame camera a 70-300mm zoom (Canon, Nikon, Sony) will get you pretty good coverage from 15 yards to 56 yards away, the ‘sweet spot’ for outdoor sports.
What is a 18 55mm lens good for? The best thing about the 18-55mm lens is its versatility. At 18mm, it is fairly wide-angled and is great for landscapes. In the middle of its range, around 35mm, it is perfect for street, travel, and documentary photography, while the short telephoto zoom of 55mm works wonders for portraits.
How long does it take to catch star trails?
Typical exposure times range from 15 minutes to many hours long, depending on the desired length of the star trail arcs for the image. Even though star trail pictures are created under low-light conditions, long exposure times allow fast films, such as ISO 200 and ISO 400.
How long should my shutter speed be for astrophotography? By far the simpler of the two popular rules for astrophotography is the 500 rule. It recommends that your shutter speed is equal to 500 ÷ Equivalent Focal Length. So, if your full-frame equivalent focal length is 20mm, the 500 rule would suggest that you use a shutter speed of 500 ÷ 20 = 25 seconds.
How long do you have to be exposed to astrophotography?
You want to use a long exposure time (slow shutter speed) when doing astrophotography, this will give your camera’s sensor enough time to record those little dots of flickering light. Usually, a good place to start is somewhere in between 20 seconds and 30 seconds.
What is better f2 or F4? An f/2.8 lens will give you twice the shutter speed of an f/4 lens when shooting with the aperture wide open. If you find yourself photographing moving people or other moving subjects, where fast shutter speeds are critical, then the f/2.8 is probably the right way to go.
What is better f/2.8 or F4?
A lower f-stop (such as f/2.8 or f/4) will result in a brighter image by letting more light through. However, when you open up the aperture like this (f/2.8 or f/4), you’re going to get a much shallower depth of field. This is where you’ll get that infamous bokeh you’ve come to know and love.
