Is Sigma 50 1.4ART lens more suitable for half-frame cameras or 85 1.4ART lens?

Which is better, 50 1.4 or 85 1.4, depends on whether it is installed on all or half of the SLR. Generally, 80-85 focal length is recognized as the most suitable focal length for portrait shooting on a full-frame camera, while 50 camera is similar to the human eye and often gives the impression of "no feeling", so it is of course 85/ 1.4 contrast on a full-frame camera. However, the actual focal length of the lens on a half camera is often multiplied by the coefficient of 1.5- 1.6, so the focal length of 50 is almost 80, which is naturally better on a half camera.

Second, if you are a local tyrant, then pursue one step in place. Canon 50mmF 1.2 is one of the most suitable photographic equipment for shooting children at present, which is matched with Quan Huafu fuselage. It won't be bad, but I'm afraid I have no money.

In addition, this combination has shortcomings, that is, it is too heavy. It is not as light as the Canon 200D/800D with 50mmF 1.8STM, so it can be carried around every day and taken photos anytime and anywhere.

Third, the 50mm lens used by Canon SLR and Sigma 50mmF 1.4 are not recommended. After all, it is heavy, and the body with half a frame is not good. Suitable for wedding photography, suitable for adults, but not suitable for children. After all, focusing is more demanding.

If it is a pose, that is, it is still shooting, then Sigma 50mmF 1.4 is a good substitute for Canon 50mmF 1.2.

Fourth, Canon 85mmF 1.8, this lens is a bit old, even so, if it is a home user, I would recommend it first. The price/performance ratio is here. And light. And its substitute, Longteng 85mmF 1.8, although it has more optical image stabilizers, you can't slow down the shutter speed when shooting lively children, so the shutter speed must be increased. Therefore, optical image stabilization is really of little use for shooting dynamic children. At the same time, Longteng 85mmF 1.8 is still a little bulky, which is not suitable for the daily shooting needs of home users.

Is Sigma 50 1.4ART lens more suitable for half-frame cameras or 85 1.4ART lens?

Sigma 50mmF 1.4 is too heavy, unnecessary and not for making money.

Besides, what can APS fuselage do?

Your question is very specific. I recommend the following to you:

First, if you are a digital SLR of Canon and Nikon, then your problem is not the real problem.

1, in fact, no matter which brand of digital SLR, APS format and Sigma lens are not recommended.

2. Canon has 50mmF 1.8STM and 85mmF 1.8, which are completely enough for personal use and household use. It's light and very good.

3. Nikon also has 50mmF 1.8G and 85mmF 1.8G, which are enough for its own use and home use.

In fact, these two scenes of Sigma are mainly used for work and making money. They are huge in size, strong in appearance and professional in appearance, and customers are easy to be satisfied when undertaking business. When you use such a powerful lens, customers are relieved.

These two scenes of Sima are purely working to make money.

However, if you use APS fuselage, what business can you undertake?

Think too much?

Second, if you are an APS digital micro-single from Canon, Sony and Fuji, your problem is even less of a problem.

Because both Canon and Sony have three musketeers, it is more appropriate.

Sigma 30mmF 1.4, 56mmF 1.4 is more suitable for digital micro-single.

As for Fuji, Fuji has its own fixed-focus lenses of 35mm, 50mm, 56mm and 90mm.

Moreover, the color technology of Fuji micro-single must also be matched with Fuji's own original lens to truly reflect it.

To sum up, your question is a false proposition. APS fuselage doesn't need a bulky lens like Sigma.

It's best to use a lightweight lens.

For non-full-frame cameras, it is recommended that you use a focal length of 50 mm

Quan Huafu digital camera refers to the film size of its photosensitive original CMOS relative to the traditional 35mm film camera. Full-frame digital SLR cameras have the same size as film, and CMOS cameras smaller than 35mm film size are not full-frame cameras.

However, for non-full-frame cameras, because the CMOS sensor is small, it will be multiplied by the focal length conversion coefficient of 1.6, resulting in the focal length loss at the wide-angle end. For example, a 16mm lens can shoot a wide angle of 16mm on a full-frame camera, but the wide-angle end is only 25mm on a non-full-frame camera. Especially when shooting scenery and taking photos with many people, the full-frame camera has obvious viewing angle advantages and can accommodate more scenes.

So a 50 mm lens for a very non-full-frame camera is basically equivalent to an 80 mm lens.

About 50- 1.4, and 85- 1.4, which is more suitable for half-frame cameras. I think this is a misunderstanding of the use of half-frame and full-frame cameras. Without lens, it can only be used for half-frame or full-frame cameras. No matter what kind of lens, half frame, Quan Huafu and camera can be used.

1, as long as the camera bayonet is unified, the lens can be used for any camera.

Photography is a profound optical art, and there are no fixed rules. The specifications and usage of the lens are just a product introduction of the manufacturer.

3. Canon 700 camera can also be used with 70-200 camera. Let people see it, saying it's too ostentatious.

If you are a real photographer, you can be shocked by his fear of shooting with a mobile phone. It's just for people to see, and the photographic equipment used is not professional.

5, photography at the same time, can not be bound by original thinking, so it is difficult to shoot a good film.

It was announced on the Internet that a Japanese old man especially likes the lotus flowers in China and comes to China to photograph them every year. Therefore, the photographic equipment is an ordinary digital camera. He made the lotus flowers vivid and wonderful. A good film is not necessarily a good lens, but a good machine. The connotation of photography is how to compose a picture and make good use of the function of optics. If the proportion of the scenery is properly grasped. Everything should be applied, and he has nothing in common. If he doesn't master and use photography flexibly, no matter what equipment and lens he uses in photography, it is difficult to make a good film.

Hello, subject, what kind of lens to choose depends on what subject to shoot.

The focal length of 50mm camera lens is closer to the range seen by human eyes. For a half-camera, the focal length is multiplied by the coefficient of 1.6, so the focal length of 50mm is equivalent to 80mm, and the focal length of 85mm is equivalent to 136 mm ... If universality is considered, a 50mm focal length lens is selected. The focal length of 85mm is a bit too long, unless a telephoto end is needed for special shooting.

In short, the focal length of 50mm is commonly used and can adapt to most shooting situations. 85mm focal length is far, but the range is small, which can be selected according to the specific situation.

These two heads look like mine for a long time and have a good impression. I started to use 50 from the half frame machine. After using the whole frame, I lost 50 and changed it to 85, which is a bit unreasonable. It is generally believed that the equivalent focal length of about 80 is the golden focal length of portrait shooting, and 50 is too real, which will give people the impression of "no feeling". The charm of art lies in that it comes from reality and is slightly higher than reality. The equivalent focal length of about 80 balances authenticity and artistry well. If you use a half-frame machine, it will be more appropriate to use an equivalent focal length of 50 for about 80. Of course, if you choose 85, the sense of fuzziness and space compression will be better, but the scope of application is still not as good as 50.

Send some portraits I took with Sigma 50 when I was playing with half a camera.

I don't know what the jumping friends want to shoot. Because it is a half-width machine and the focal length is calculated by a full-width machine, it should be multiplied by the conversion coefficient of 1.6.

If most people shoot portraits with a focal length of about 85, it is recommended to choose 50 1.4(50* 1.6=80), and if they shoot landscapes or city streets, choose 85 1.4.

The quality of Sigma art series lenses is very good. Choose according to the subject you want to shoot.

50 1.4art or 85 1.4 art is more suitable for frame clipping?

50 1.4art is more suitable.

The focal length of the golden portrait is 85 focal length; However, the frame cutting should be multiplied by the coefficient 1.5/ 1.6, so we choose 50, which is equivalent to 85 focal lengths after multiplying by the coefficient.

Multiplying 85 by the coefficient becomes the focal length of 127/ 136.

Look what you took! The choice of equipment must depend on the application scenario, and it is hooliganism to recommend equipment without using the scenario.

50 is used on a half-frame machine, which is equivalent to 75. This lens is quite good. 85 is a classic portrait focal length, but it is equivalent to almost 130 when used in half a picture. It depends on your usage scenario. If it's not big enough, it won't open. If it's wide enough, it's far enough away from the model to take a full-length photo. You should think about communicating with models.
