Canon 50 header does not want UV mirrors Canon 50 1 4 .

Add a glass piece such as UV in front of any lens, and the image quality will be reduced to varying degrees, but the best UV can minimize this loss.

The main purpose of installing UV is to protect the lens in the era of digital photography, and it can generally be dispensed without. Unless it's an expensive lens, or it's raining or when you're going to the beach. For the header, ** is not expensive, so in general, you can choose not to use UV to ensure the quality of the image, of course, this is also everyone's own decision, some people put the protection of the lens in the first place, do not want to wipe the lens frequently, so they will also hang UV all day long.

When shooting night scenes, UVs are generally not hung to avoid light spots.

It doesn't matter whether you want to use a UV mirror or not. Because the UV lens is an ultraviolet filter, its main function is to filter ultraviolet rays, because when photographing with film, due to the chemical characteristics of the film, the film is more sensitive to ultraviolet rays. However, in the digital age, the image sensor of the digital machine is far less sensitive to ultraviolet rays than film, and in an environment where ultraviolet rays are not particularly strong, there is almost no difference between shooting with and without a UV lens.

Therefore, in most cases, the use of UV lenses in the digital age only serves to protect the lens. The installation of UV mirrors, after all, has an impact on imaging, but a good UV lens will minimize this impact and is almost invisible, and only the ** with particularly high requirements for image quality needs to consider the impact of UV lenses.

Not in any case you need a UV mirror, first of all, you must know the role of the UV mirror, its main concern is ultraviolet rays, when the ultraviolet rays are strong, it should be used, otherwise the sky looks too blue. Now the UV lens is mainly used to protect the lens, because the first piece of the lens is in the air, it will inevitably be affected by dust, fingerprints and hard objects, poor imaging, plus digital imaging and the past film imaging is different, the impact of the UV lens on the digital is not very large, so everyone basically regards it as a lens protection lens.

Is it serious on 60d? The best value for money is, of course, Canon's 50. Sigma's head has no cost-effective advantage compared with Canon's. Definitely not, otherwise he has more than 3000 lenses.

The filter diameter of this lens is 58mm, and a 58mm UV lens is sufficient.

As for which one to choose, as long as it is a product of a regular manufacturer, it is not ......After all, the technical content of the UV mirror is not high, as long as you do it carefully, it is not bad!

The focusing noise is smaller, with the help of the STM motor, the EF 50mm STM's minimum focusing distance has been shortened from 45cm to 35cm, the close-up shooting ability has also been significantly enhanced, and the original plastic mount has been changed to a metal mount, although it is worth buying for 100 yuan more.

I have this lens, with 60D to use, quite an 80mm lens in APS-C format, it's really good to shoot portraits, but after using it, I found that the aperture is almost sharp, and the background blur of the large aperture is also good, compared with the zoom lens lens, it is basically a frame that runs by running, hehe.

Overall, I personally feel good about this footage, and it deserves to be having.

Great, it works! It's worth having.

The Canon 50 filter size is 58mm.

He is equipped with a 58 caliber UV mirror In fact, I personally recommend running naked Adding a UV mirror always affects the effect a little Especially the kind of mirror below 100 It's good not to answer stupid If you want to buy a little bit of land book to buy it is better to choose ultra-thin multi-layer coating.
