There are already Canon 135 prime lenses, is it still necessary to buy 24 70 2 8 lenses?

Yes. The 135 is known as an air cutter, and it is very good to shoot portraits, but if you want to shoot large-scale scenery films, there is basically nothing you can do.

24 70 is the most commonly used focal length, which can meet 80 90% of daily shooting needs. And the zoom has its flexibility of viewing angle, which is very convenient to use.

The function of the fixed focal head is relatively simple, and those who are good at it can do the ultimate, and those who are not good at it can do nothing.

Let's just tell you, anyone who has 2470f4 or has to continue to buy 35 50 85 135 fixed focus.

1.Aperture, your 18135 aperture, bokeh is very poor, the worst fixed focus is f2, right, and the decrease aperture is also.

2.Image quality, since portrait quality is very important, then fixed focus can give you better image quality.

To sum up, if you just want to take a casual pat, or travel, 18135 is enough.

For portraits, you must buy a fixed focus, it is recommended to buy first.

Portrait and humanity are two directions, portrait to highlight people, the more virtual the environment, the better, humanities and to include people, but also to explain the environment in which people live.

Let's talk about lens selection, portrait lens 85 set, 135 set, 200 set, you can come to one first, the original factory is expensive, you can choose Sigma, 50 can also shoot, but the bokeh effect is not as good as the above.

Humanities, 28 set, 35 set, 50 set, 28 too wide, 50 slightly narrow, 35 is the most suitable, Sigma is very good. Personally, I think that filming humanities does not need to pursue a large aperture, and F4 is fine. Actually, the one you have in your hand is enough.

Finally, let's talk about the fact that Sigma is twice as expensive as the original factory you mentioned, this lens is aimed at the original factory, so it looks like it is half cheaper. Except for Jiao, the others are not as good as the three generations.

If you need it, buy it.,These two lenses are used for different purposes.,135 is a portrait lens,And 24-70 is a standard zoom hang-up lens,

Both lenses are very good lenses, but they are completely non-conflicting lenses, and if you have 24-70, you can get another 50 prime lens. Canon 24-70 is one of Canon's large ternary lenses, it is a very comprehensive lens, it can shoot a wide range of subjects, from scenery to humanities to portraits, it is competent, and it is also the hang-up lens of many photographers. Canon 50 fixed focal length lens, in fact, this mirror Xun draft head is a lens born for humanistic portraits, because it is a fixed focal length lens, so its imaging can still be trusted, the imaging quality is excellent, the image quality is delicate, the sharpness is very high, and because it has a relatively large aperture, it is also very charming in the bokeh of the out-of-focus, this lens is a very good choice for shooting humanities, folklore and portraits, of course, this lens is used to shoot flowers also has a good performance.

In short, although 24-70 contains 50, it is still worth getting this lens if you like to shoot portraits, etc., if you are just an ordinary enthusiast, you can buy it or not, just have fun.
