70-200 is this lens increased to 70-600 with double rangefinder? Is the picture quality affected?

Hello, 70-200mm is divided into F2.8 and F4.0 No matter which one, rangefinder is actually not recommended. Let me elaborate on your question:

Canon 70-200mm is mainly suitable for news photography and portrait photography.

First, for most photographers, Canon 100-400 is the first choice.

To put it bluntly, 70-200mmF2.8 is used for news photography and portrait photography.

Most photographers actually shoot landscapes and flowers. In fact, it would be better to use100-400 mm.

Of course, the economic conditions are a little worse, and it is ok to use 700 to 300.

Second, 70-200mmF2.8, this lens, is it necessary to buy a rangefinder?

I don't think it's necessary.

If you really need to use the range extender frequently, buy100-400 mm.

Third, 70-200mmF4.0, this lens, is it necessary to buy an extender?

This is even more unnecessary.

In addition, I never recommend a 70-200mmF4.0 lens.

I only recommend 70-200mmF2.8 and 100-400mm and 70-300mm to those who have no money and are afraid of the burden.

Fourth, 70-200mmF2.8, can it be changed to 600mm?

This is twice as long as the rangefinder, which is 400 mm.

Used in APS camera, multiplied by 1.6, that's probably what it means.

5. For the majority of photographers, 100-400mm with 50mm and 85mm fixed focus is the first choice.

Much better than 70-200 with dual rangefinder.

6. Is the picture quality affected?

Well, if they are all brand-new and unpolluted, the picture quality is still ok. (Of course, it is definitely not as good as using 100-400 directly. )

But the problem is that the rangefinder has two sides, and the lens has two sides, a total of four sides. Are they all brand new?

Are they all spotless

Is it still the original brand-new product after polishing?

To sum up, it is recommended to buy the original Canon 100-400mm directly, and then match it with 50mm and 85mm fixed-focus lenses. Of course, it can also be paired with Canon Budweiser.

70-200 Magnifier +2 is 400 at the farthest, and the shooting details of the Magnifier are much worse, so the focusing accuracy cannot be guaranteed. There is no way to compare with 400/2.8. If a friend doesn't want the picture quality, you can add a magnifying glass to shoot birds, or you can shoot them at close range, such as shooting in the park, shooting in the field from a distance, and setting the focus above 400. I took a photo of Xiao Cui with the camera of 100-400, but the details are still not enough. Zoom lens can't compare with fixed focus lens.

Hello, I'm glad to answer your question.

First of all, your algorithm is wrong. 70-200 If you add a double zoom lens, it will theoretically become 140-400. The focal length increases before and after double zoom.

Secondly, not all lenses can be added with a rangefinder at will, because there are lenses on the rangefinder, some lenses have insufficient space at the rear to be screwed on, and some multiple rangefinders cannot achieve the focusing function after being put on.

I happen to have an official Nikon brochure named nikkor lens. I checked the data for you,

The matching effect of 2 times rangefinder and the following lens is good. The rangefinder of 70-200 can only be changed from 1.4 to 98-280, and the focal length does not increase much. The aperture is reduced by one step, which affects the image quality to a certain extent and the price is not cheap. Many people who need long-distance photography directly buy 100-400.

Doubling the rangefinder is not increased to 70-600, but to 2 10-600, and each focal length of it will be increased at the same time.

The lens is a very precise instrument. All lenses, lens curvatures and lens combinations are carefully calculated and designed. If a lens other than the original lens group is installed, the resolution of the lens will be affected. Especially for long focal length lenses, adding extended-range lenses is more likely to cause image quality degradation.

However, if the requirements for image quality are not high, the impact can still be tolerated. If high-quality photography is required, I suggest you buy another long-focus lens, such as 200-500mm lens and 150-600mm lens. Both Longteng and Sigma have this kind of lens, and the imaging quality is very good, and the price is about 6000 yuan. It doesn't cost much to use a rangefinder. A good rangefinder costs more than 2000 yuan, but the image can't be guaranteed, and all the pictures are scrap.

If you want to use it frequently, increase your investment and buy a new lens. You can use it with confidence, and the photos can guarantee the quality. If it is a bird-shooting work, then the key points should be clear and the feathers should be clear. If you only use rangefinder to deal with it, most of it may not be ideal.

In order to save money, the effect is not bad, increase it and compete for hegemony!

First of all, the constant aperture of 70-200, 2.8 is large enough, and the doubled distance becomes 140-400, but the aperture also becomes a constant 5.6. However, I increase the distance in the process of using it mainly to shoot birds. Compared with the lens with a maximum aperture of 5.8 in 150-400, this lens has the advantage of being constant at 5.8. The original high-quality image quality is better and the sharpness is reduced, but don't forget to take off the magnifying glass to get excellent image quality, which is beyond the reach of 150-400.

Finally, I want to express that if you buy a lens with a fixed ratio of 70-200 and 2.8, you can get two lenses, both of which are excellent in shooting people and scenery. It is also possible to shoot birds after increasing the distance. Of course, compared with 400 fixed focus and 2.8 constant aperture.

Canon 70-200 is an absolutely good lens, but with the addition of dual lenses, the image quality immediately drops and the focus is not good. As the saying goes, buying is not refined, selling is not refined. If you really like telephoto, go to 100-400. If you are not satisfied, you will lose 600,800!

First of all, look at what you mainly shoot. If you mainly shoot people and scenery, 70-200 is enough, and the usage rate may be lower and lower because of the weight problem.

If you shoot a bird, it means that 70-200 was bought wrong, and the lens did not solve the demand. Even if the zoom lens is doubled to 400, it is still a little close for shooting birds.

In addition, the maximum aperture of the lens will be reduced by one level after adding the rangefinder, and the image quality will be reduced. At this time, the range finder is a little chicken.

According to the idea of buying a range finder, it is proved that there may be a need to shoot birds, but the probability of using it is relatively small. In that case, it's better to rent a lens if necessary. It not only solves the demand, but also reduces the occupation of a lot of funds.

The third impression of Matterhorn was taken at 70-200, and the first two must be [cute].

4-6 is someone else's 600. If you shoot birds, let's set it at 600 [yi tooth]

Answer this question with a recent movie. The following pictures were taken with Canon 90D+70-200 MMF 2.8 II+ Canon 2x rangefinder.

70-200 plus a magnifying glass. It becomes 140-400. If it is a constant aperture of 2.8, the maximum aperture becomes 5.6. Auto focus is acceptable. If the constant aperture of the lens is 4 and the maximum aperture is 8, then the camera cannot focus automatically. The brightness is less than half, and the picture quality has some influence. The requirements are not high and can be ignored.

The original question is, is the 70-200 lens increased to 70-600 with dual rangefinders? Is the picture quality affected? I read the other answers carefully and then explained in detail that the 70-200mmF2.8 lens and TC-2X rangefinder on Nikon C-frame SLR fuselage increased from 70-200mmF2.8 to 2 10-600mmF5.6, and the image quality was affected.

Canon SLR 70-200mmF2.8 weight 1480g, TC-2X rangefinder 325g, 100-400mmF4.5-5.6 weight 1570g.

Sigma 60-600mmF4.5-6.3 weighs 2700 grams.

Nikon SLR 70-200mmF2.8 weight 1430g, TC-2X rangefinder 330g, 80-400mmF4.5-5.6 weight 1480g.

Of course, compared with the bird-shooting method with 400 fixed focus and 2.8 constant aperture ... the focusing speed and image quality of the original 400mm zoom lens are probably still "wooden shots".

C-frame SLR fuselage original 200mmF2.8 zoom lens plus TC2X rangefinder (with coated magnifying glass? Earlier years 135DF imported rangefinder memory may not be accurate) It is equivalent to 600mmF5.6 comparison 135 Quan Huafu150-600mf5-6.3 Sigma C version S version Longteng II and Sigma 60-600mmF4.5-6.3 Look at Canon SLR 200-400mm.

As for how much the bird-shooting focus speed drops, is it slower than the 150-600mm lens of Longteng Generation and Sigma C, depending on which fuselage it is, and whether it is the same brand model of the flagship of C Quan Huafu Speedshot, then there is no need to compare it, and it is certain that the two flagship models of 135 Quan Huafu will definitely win.
