Canon 600d 18 55 set wants to change 17 40 red circles

Let's talk about the 17-40 and 15-85 shots:

First of all, the difference in image quality between the two is very small, and the difference in aperture is not large, and the constant F4 is not much stronger than the floating aperture in actual use. The advantage of 17-40 is that it is a full-frame lens, with a focal length of 27-64mm on 600d, internal zoom (the lens will not stretch out when adjusting the focal length), which is more suitable for taking landscape photos with a filter, and the imaging quality is good at a small aperture, the distortion is small, and the lens is well workmanlike (after all, it is an L lens); The biggest drawback is that the focal length is not long enough, which is especially noticeable when traveling, and you will find that there are many things you want to shoot but can't, and the image quality at the maximum aperture of f4 is mediocre. The biggest advantage of 15-85 is that the focal length is good, from 24mm wide angle to 136mm medium telephoto, whether it is indoor or outdoor, you will not feel that the angle is limited, the second advantage is that there is an anti-shake function, which is still very effective when the environment is dark (17-40 has no anti-shake), and the elongation of the focal length of the lens also plays a role; The disadvantage is, of course, that the aperture is not large, the workmanship is not as good as the L-head, and it is certainly not as good as the inner zoom lens in terms of using filters.

If you ask which of these two lenses to choose, it's actually very simple, choose 17-40 for the full frame, and 15-85 for the half frame, of course, so don't worry too much.

Since you are using a 600d and do not plan to change the machine, then the 15-85 is more suitable.

17-40 is full-width, 15-85 is half-width, and if you're going to go full-width 17-40 in the future, it's better to use the coefficient that you have to multiply on 60d.

As long as the lens focal length is multiplied by the actual focal length of the aps format, if you don't change the camera, you can use 15-85, which is quite cost-effective and practical.

17-40 and 15-85 compared with the advantage is not very obvious, in the light rain without an umbrella, everyone will recommend you to choose 17-40, the performance of these two lenses is comparable to the **comprehensive comparison, it is recommended to choose 15 85, the focal length advantage is obvious.

There are red circles for episodes to choose 17 40, otherwise accept my suggestion.

Support continues to ask questions, help you analyze, and help you solve problems.

15-85 converted focal length wide angle 24The wide-angle end of 17-40 is for your own look. 17-40 is ultra-wide at full-frame focal lengths.

The price of 15-85 is much more expensive than that of 17-40. If you want to upgrade the full frame in the future, buy 17-40, if you don't upgrade, I recommend that you sell 18-55 and buy 15-85.

If you plan to play full-frame in the future, you can't go wrong with 17 40.

15 85 is a 7D pullover, the quality is very good, if the requirements are not high, the APS format can go all over the world, its 15m wide-angle segment is very attractive. It is a rare good head under the APS format.

The cheapest prime head you mean 50 bar, this head is highly not recommended, it has a very low film rate at a large aperture, about 1 3 or so available. It is recommended that if you buy it, the one you choose, of course, it will be 3 times more expensive.

Then decisively 15 85 plus 50 . It's just ** going to exceed your budget.

Canon 55 250, the bokeh effect is good, the focal length of 250mm is long enough, the aperture is enough for beginners, compared to Xiaoxiaobai, it is small and lightweight. **Cheap.

17-40 is not recommended

16-35 is recommended when rice is plentiful

The performance is much better than 17-40, and it is also one of the big three elements if you upgrade the full frame in the future, note that if you want to upgrade the full frame in the future, you can only choose the lens of EF, and the EF-S cannot be installed on the full frame machine.

17-40 is the worst one in the red circle, and it is called a pseudo-red circle, so it is not very recommended to buy. But the picture quality is better than the sleeve, that's for sure.

First of all, you say that you don't have enough shots, but what are you going to shoot? In daily life, in fact, the distant view is rarely used, and I don't know what the landlord is going to shoot.

There is no far-and-near lens with good imaging, because the magnification of the zoom lens directly sacrifices imaging, such as 18-135 18-200, especially the latter, and the imaging ability is even more messy; It's actually not difficult to figure it out, 2 points 1 is that your lens sharpness is enough, 2 is that you can use ps screenshots to take a screenshot These 2 are actually very simple, but your 18-55 is not good This head is not sharp enough.

Landlord, let's first talk about why you need to shoot long shots, and then I can recommend long shots for you individually.

If I were you, and I had a 5k budget, the first thing I would change out was the lens that you hung up, which was the 18-55, and this lens was the most used.

5K budget You can consider 15-85 and 24-105L The former imaging is okay, but the disadvantage is that the aperture is small; The latter is a red circle, of course, it is not a good red circle, the imaging is slightly better than 15-85 The focal length is also slightly longer, the disadvantage is that there is no wide angle, which means that you can't shoot a wide angle**.

These two heads are within your budget, and you can choose 1 of 2

Let's talk about telephoto zoom lenses.

In the telephoto, the imaging is okay, and it is within your budget, which is a little white.

The 70-200 f4l is also a red circle, certainly the worst red circle at this focal length.

But the emaciated camel is bigger than the horse, and this imaging is at the same level as 24-105, which is naturally much better than your 18-55, and the focal length is not long or short, and the general long shot can be completed, but your current situation is not suitable for buying this, first of all, this lens is directly about 5k.

You bought this, and you can't hang it up yet, because the shortest focal length of 70 can't be used indoors

So to sum up, it is recommended that you change the lens of the hang-up, and then if you must consider telephoto, then this little white.

Novices are not recommended to use telephoto Many people who are novices are hot-headed and buy telephoto and then they are not all idle

So the landlord thinks twice, welcome to ask.

The commonly known as the tourist head, there are 18-135, 18-200.

However, you don't have to think about one lens to solve all the problems, it is recommended to have a telephoto 70-300 long shot first, with a 35 header.
