Is it necessary to buy 100-400 zoom for Canon 400 fixed focus?

It's totally unnecessary. You may think that you can zoom with 100, but I believe that your lens has a focal length of 100-200 as small as white. 400 fixed imaging is better than 100-400. I hope to continue to use 400-my humble opinion.

This is 400/5.6.

Is it necessary to buy 100-400 zoom for Canon 400 fixed focus? As for the choice of lens, it is mainly related to our shooting needs. We have different shooting preferences or themes, and we can choose the corresponding lens according to our main shooting direction.

Canon 400 fixed focus can be said to be a good lens for shooting news sports and bird ecology. The lens is big and heavy, which can be said to be a relatively specific lens, but do you need to increase the white lens? It all depends on whether you need or don't use that focus segment often.

If you sometimes need to shoot some scenery, portraits, flowers and other subjects, I think it is absolutely necessary to buy a medium-long zoom lens. Of course, white or white will do.

To tell the truth, the 400 lens that we seldom use at ordinary times is really a more specific lens, and some shots in daily life are almost useless, so we need to add one or more commonly used lenses to the camera, such as wide angle and medium focus. Wide angle can be used to shoot landscapes, medium focus can be used to shoot portraits or snapshots, and your telephoto can be used to shoot birds and other subjects, and the two are not in conflict.

The above is my opinion, welcome friends to add.

Sword dance images, western photographers, looking forward to attention.

I use both 428 fixed focus and 100-400, so the answer to the subject's question should be representative.

Simply put, the ultra-long-distance fixed-focus lens is mostly used for fixed-point shooting, because the lens weight is not suitable for wandering and hand-held random shooting. 100-400 is much lighter, so it is mostly used for instant shooting with hand-held wandering. These two kinds of lenses have their own requirements, and the application scope of 428 is relatively small, and the application scope of 100-400 is wider. As for the picture quality, there is not much difference if you shoot from a long distance. The following pictures are 20 100-400 lens +7D2 camera, 428 lens +2 rangefinder +5D4 camera shot in the same place on 20 18 and 20 19 respectively. 100-400 takes into account the scenery.

The above four pictures were taken in the 7th D2+19 generation.

The above two pictures were taken on 20 18 with 5D4+428+2x rangefinder.

While the image quality is improved, the mirror body is lightweight.

Rf100-500mf4.5-7.1l isusm adopts a brand-new optical design, which has the same or even higher image quality as ef100-400mf/4.5-5.6lis ii USM. Compared with EOS 5d mark iv plus ef100-400 mm f/4.5-5.6 l is ii USM, the telephoto end is lengthened to 500mm, and the weight is reduced by about 14% on the basis of basically unchanged length. The mobility and portability of the telephoto lens are further improved.

The suggested retail price of EF 400mm f/2.8L IS III USM is 87,899 yuan. Finally, the mirror weighs only about 2840 grams, which well responds to the demand of professional photographers for lightweight and high-quality telephoto lenses. While improving the shooting flexibility, because the center of gravity of the lens moves backward, it can be more labor-saving and easier to shoot for a long time when using a monopod or hand to follow the shooting. In addition, the lightweight lens is not only convenient for handling and carrying, but also brings great convenience when riding on vehicles such as airplanes with weight restrictions on checked baggage. Jitter will become obvious with the increase of focal length, especially when shooting with telephoto lens, even slight jitter may be amplified in the photo, leading to shooting failure. This puts high demands on the anti-shake performance of telephoto lens. The IS image stabilizer unit equipped with EF 400mm f/2.8L IS III USM adopts a new specification microprocessor, which effectively improves the processing speed. The high-performance gyroscope and optimization algorithm improve the hand shake compensation effect from the previous 3.5 ※ 1 to 5 ※2, which can effectively suppress the hand shake that is easy to occur in telephoto lenses. The substantial improvement of IS performance, coupled with the weight reduction of the lens itself, makes hand-held shooting easier. Moreover, when shooting in a dim scene with insufficient light, thanks to the strong IS performance, you can use lower ISO sensitivity, thus obtaining high-quality images with less noise.

The suggested retail price of EF 400mm f/4 DO IS II USM is RMB 49,599, which is a super telephoto lens with high imaging performance and portability. Large aperture telephoto fixed focus lens with DO lens. The lens is about 24 cm long and weighs about 2. 1 kg. As a telephoto fixed-focus lens, it is light and portable. It caters to professional photographers' desire that telephoto lenses can also be shot by hand, and can play a role in news reports, wildlife, racing and other fields.

The suggested retail price of EF 400mm f/5.6L USM is 9449 yuan. Although it is a 400mm focal length lens, its weight is only about 1.250 g (including the built-in hood), which is the lightest in the EF lens series. Although it is not bright, its good portability is suitable for sports photography such as golf and wildlife photography in Shan Ye. The cost performance is high, and it is quite competitive in telephoto lenses over 300 mm Although the lens structure is simple, the imaging at the maximum aperture is also sharp, with good contrast and high imaging power. Moreover, the amount of surrounding light is reduced very little, and the color development is rich and expressive. The focusing mode is back focusing, and with the annular USM ultrasonic motor, quiet and high-speed automatic focusing can be realized. Equipped with double-layer focusing ring, pull out the built-in hood to expose the focusing ring with larger diameter. You can choose the appropriate holding posture according to your own habits and shooting environment. Thin and compact, L-class super telephoto fixed-focus lens, 400mm focal length. In the lens structure of 6 groups of 7 lenses, the second lens adopts super UD (super ultra-low dispersion) lens, which can obtain the color difference compensation effect equivalent to 1 fluorite lens. The fourth lens adopts UD (ultra-low dispersion) lens, which can effectively suppress the occurrence of residual chromatic aberration. The use of special lens realizes sharp and high contrast imaging effect. Simple optical structure and appropriate aperture make the lens lighter.

The original question didn't write which lens of Canon 400mm fixed focus? There is a difference between weight and price. I suggest you buy a five-axis anti-shake R6 micro-lens, equipped with RF100-500mf4.5-7.1lisusm anti-shake lens.

Among 400 fixed zoom lenses, 400f2.8IS II has the best picture quality, followed by III, and DO is similar to 200-400IS 1.4X, followed by others. Personally, I think the most practical one at present is 200-400IS 1.4X, which is 10,000 yuan cheaper than the f2.8III generation. The rangefinder switch is easy to use.

However, when it comes to image quality, if you buy a fixed focus, you will obviously feel that the dark angle, dispersion and focusing speed of zoom are worse. If there is an extreme demand for image quality, it is better to go directly to 400f2.8. If there are many later stages, it is actually a good choice to match the fuselage with 1dx2 and x3, and go up to 200-400 IS1.4x. ..

If you have 428, there is no need to buy 100-400! If it is 456, it is better to change it to 100-400 second generation!
