What does 50mm mean when it is equivalent to 450mm on 80D?

Because the focal length is related to the film format, the 450D image sensor is smaller than the 35mm film format, and the focal length of the lens is the standard under the 35mm format, there is a multiple conversion relationship between the two, and the actual focal length it is mounted on the 450D is 80mm, which has nothing to do with how many meters it is from to shoot, as long as it is suitable within its focusing range. Generally, it can be focused from more than ten centimeters to infinity.

It is equivalent to the angle of view of an 80mm lens on a 35mm full-frame camera.

The focal length is still the same focal length, and what changes is the angle of view.

Because the 450D is a Canon APS-C format SLR. The lens conversion factor of the Canon APS-C format SLR is . So when the 50mm header is mounted on the 450d, the focal length of the lens is multiplied.

Therefore, a 50mm focal length lens is equivalent to 80mm on the 450d. Similarly. Nikon and Pentax, Sony and other brands APS-C format SLR lens conversion factor is multiple.

The 50mm standard lens is mounted on the APS-C format SLRs of these three brands. It becomes a lens with a focal length of 75 mm. Does the landlord understand?

The digital sensor of a Canon camera is not the same as that of a conventional film, so the lens is mounted with a multiplier factor, which is why the 450D is not a full-frame camera.

50 is very cheap 50 autofocus is more expensive 2700 new, the others are more expensive, choose one of the two.

1. The landlord asked: Can a 450D SLR be connected to an 80cm portrait lens?

Answer: What does the landlord mean by 80cm here? Lens focal length? That long focal length? 800mm？！That's not a portrait lens, it's a super telescopic lens!

Of course you can.

The equivalent focal length attached to the 450d is 1080mm.

Second, the landlord asked: What model is suitable for matching and how much is the price?

Answer: If you mainly use 450D to shoot portraits, I personally recommend using EF50mm, and the equivalent focal length connected to 450D is 80mm, which is very suitable for portraits.

**Approximately $2,700.

As long as it is a Canon EF mount, you can use it (other mounts can also be adapted, but you can't autofocus), you can look at the original 85, or you can consider the Sigma 85.

Originally, the 50mm prime was a 35mm camera head, which is suitable for shooting portraits with the whole body or half of the body, but in the case of the DSLR (APS format), the non-full-frame CMOS size of the Canon is the equivalent of the 80mm focal length of the full-frame DSLR on the Canon 450D (it should be noted that the equivalent of the focal length is not entirely accurate, but it is not the focus of our question). Therefore, in actual use, the 50 header is far away from taking portraits on APS format SLR such as 450D.

If you have to shoot indoors and space is limited, consider a prime head of around 35mm, or a wide-angle zoom head with a larger aperture. For novices, the zoom head may be easier to get started, the fixed focus head belongs to the composition, and if there is not enough lens sense, or the space is limited, it is often not easy to shoot well**, and the zoom head is much freer. The biggest advantage of the fixed focal length is that it has a large aperture, which is very advantageous for indoor shooting.

If the light can be guaranteed, I think the 450D pullover is no problem, after all, you just send a product picture on the **, and you don't require any high image quality.

As for the blurry picture you mentioned, I guess there are two aspects, one is the problem of focus. It's easy to lose focus when the aperture is wide open on 450D, especially when the light is low (it is said that the focus is very accurate on 5D, I haven't used it, I've heard it, hehe). Let's try to reduce the aperture by 2 stops.

Again, for novices, it is likely that there is a problem with hand shaking, especially when the optics are dark. You see**, is the whole picture pasted, if so, the hands are shaking. The solution, one is to open the aperture wide and increase the shutter speed; the second is to turn on the flash, or use the camera light reflector and other equipment; The third is the tripod.

This lens is used on the 450 as a mid-focus lens, as long as the camera is held steadily, the focus is correct, and it will not be confused.

Technical issues.

Good lighting The aperture is opened to the tripod, and the reflector will not blur when it is pre-raised.

Distances are normal.

This is a problem with the camera and the lens itself, the Canon's imaging is inherently soft, giving the impression that it is a bit blurry, and the Canon 50 is already a problem of insufficient materials, so the expectations for imaging should not be too high.

You can improve it by adjusting the sharpness with the Canon attached software, and there doesn't seem to be a good way to do it at the moment!!

With a tripod and a shutter release cable, but also the light.

First of all, congratulations to the landlord for buying a new machine.

50mm is a portrait prime that is used to shoot down pants. Personally, I don't think it's a headset, right?

And then there is the main floor to shoot very clearly, you can get closer, 50mm with macro, the nearest focus should be 45cm. The reason for the blurring may be that your focus point is not on the subject or it is caused by shaking, and it is recommended to buy a corner bracket to solve the problem.

It doesn't matter whether you can use it or not, it's limited by the angle of view of the lens. 50 On the 450d, the equivalent focal length is 80mm, and if you are a 170cm full-body standing figure, you will need to retreat to about 5 meters to take a picture.

The 450D is an APS-C size sensor, so the focal length of 50 should be multiplied by a multiple, which is about 80mm equivalent focal length, and the 80mm segment is generally used to shoot the half of the person, or a close-up of the face. Of course, if you want to shoot your whole body, you naturally have to stand far away.

Suggestion, 17-85 This head is quite reliable. Or a 7D set of heads 15-85 is OK, 18-200 is OK. I'm paired with Tokina 11-16, Canon 24-70, Canon 50 and I'm going to go on a 70-200 at the end of the year

It's fine to use a wide-angle lens, and it's good to shoot a person's head at half a frame with a 50 prime focus.

To be honest, if you don't want to be professional, you can use the original 18-55 pullover, the effect is also good, and it is cheap.

I used Tokina's 19-35 myself, and it worked well. Mainly**suitable.

The equivalent focal length is based on conventional 35mm film.

Conventional film, on the other hand, has a photosensitive area of 36x24cm

However, the area of the current APS-C format SLR is 24x15 centimeters, so it needs to be converted.

The conversion factor of Canon is.

So 50mm is equivalent to 80mm.

Conversion of equivalent focal lengths. In fact, the image sensor is smaller, which is equivalent to the effect of a lens with a longer focal length.

The size of the sensor is different, and focal length switching is required.

It depends on your needs, what do you want to do when you buy 85? Take portraits? Since you have XXB, try to make good use of it, and don't keep thinking about buying lenses for a certain subject, and in the end you won't use any lens.

It is not recommended that you buy the 450D, the equivalent focal length of the 50 on the 450D is 80mm, but the physical focal length is still 50mm, and the optical effect is still the header effect of 50mm, which is completely different from the optical quality of the 85 on the full frame.

The camera end is a little painful, hehe, xxb is already very light, there are two solutions, first, it's okay to take dumbbells; Second, buy a tripod (tripod or monopod will do)!

First of all, yours ** is not quite right, although 5D is an old guy, but its single machine is not only 8000, the new machine is more than 12000.

The 450d dropped a little bit.

5D is a full-frame camera, and a 50mm lens is 50mm for 5D, and a factor to be multiplied for 450D, thus equivalent to 80mm (50*) on 5D

The 450D is positioned at the low end, while the 5D is positioned at the mid-range, and although it has been 3 years since the 5D came out, it is still the main force in the full-frame camera.

Recently out 5D II is the follow-up to 5D.

The performance ratio of the two has nothing to do with **.
