40D ready for Sigma lenses, okay?

It is not recommended, the body is never as important as the lens, and generally 70% of the total investment is invested in the lens.

If you are sure that you have a follow-up investment, you can buy a transition head, if you want to be in place at one time, then the lens must be in place! Remember.

Domestic beginners in photography regard the equipment as more important than the technology The technology is not too hard to blame the lens is not good In fact, you only need to look at the Sigma Guan Fang sample shot is still very good Of course, Sigma 24-70 and the price can be 24-70 can not be compared But ** is worse than 7000 yuan! It's better than the professional and popular.

Professional photographers have higher requirements for equipment while their skills are excellent, which helps to shoot better.

Sigma 24-70 is definitely worth it to practice your skills In the future, you have higher requirements, and you have sufficient funds, and Canon L-class lenses are of course the best choice.

The hobby can.

Serious photography studios are still better to buy.

The lens is like this, can buy a good one, and don't want to be bad.

This head is not bad (for amateurs, of course).

As long as the focal length is right for you.

There's nothing wrong with that.

Sigma has a 24-70 I heard it's okay, but I still recommend a lens around 18-50 is more suitable. 40d is a good machine, sorry for the machine with a rotten head.

Canon's original state sparrow lens can't afford to accompany Ah Pina, because it's much more expensive than 40d.

18 55 More than 6,000 Are you worthy?

The reality is that I don't choose Canon if I don't choose it, and I didn't choose the Sony A350 to accompany the 17 50 of Tamron or Sigma

Definitely stronger than the 40d set.

First of all, it can be used, as long as you buy the Canon mount one.

The focus can be said to be sufficient for use. In fact, all lenses will be out of focus, it's just a matter of publicity.

Sigma lenses, however, do suffer from occasional focus issues. The reason is that the encoding of the Sigma lens corresponding to the Canon mount is cracked. In other words, Sigma did not pay this part of the money to Canon, and Canon could only passively resist, so using a Sigma lens with a Canon body is not a good choice in itself.

The biggest advantage of Sigma lenses is that they are cheap. It's still okay to use it once.

Accurate focusing depends on the camera's autofocus, and the 40D is a professional camera with a body motor, so of course there is no problem. As for manual focusing, it depends on your technical play. It's just that after the Sigma 24-70mm is converted to the Canon coefficient, it becomes 38-112mm without a wide angle, which is a little regrettable.

As long as the quality is passed, of course, the focus can be accurate, and the focus is not accurate, indicating that the product has a problem.

As long as you say hello to the Canon mount, 40D will work.

Sigma's 24-70 chance of running out of focus is relatively high.

It's better to pick it yourself.

The luck component is important.

I use the n family d90, with the Sigma small black 4 does not run the coke, C is not very clear, go to try it will not know, the manufacturer's maintenance points are adjusted.

If you are real, it will be the same as if it were a fiction. The Canon itself is not as sharp as Nikon. In addition, the imaging quality of the Sigma head is not good, and the feel is poor.

We recommend you to use Taldragon! Much sharper than Sigma. It's even sharper than the original Canon, which just makes up for Canon's soft imaging.

If it's broken, it will run out of focus, and if it's not broken, it won't

There is a phenomenon of out-of-focus, but sometimes it is suddenly out of focus. Mainly the deputy factory head, there will be this phenomenon!

For the interior view, it is good to use a pullover. Or 17-40 for those who require a high point. The main thing is to supplement your focal length below 24mm.

For exterior scenes, you still have to rely on the two focal lengths of 50 and 85, mainly to supplement your aperture. If you have money, you will enter, and if you don't have money, you will enter. After all, the exterior is very dependent on the aperture.

70-200 What else do you recommend, if you have money, you will be a little white, and if you don't have money, you will be a little white. Although Sigma's Xiaohei has good imaging, the mechanical quality is worrying, and the mechanical workmanship of the Tamron Dragon Cannon is good, but the imaging is average. In contrast, Xiaobai and Xiaoxiaobai are more suitable.

50 is very good,,In view of the fact that it is APS-C,Not the full width,85 and 135 don't have to,It's too far,It's not convenient to communicate with children

Let me recommend it to you, your main shooting is people. So the lens I'm considering for you is a prime lens, with a focal length of 50 mm or 85mm

Here's the analysis.

How much are you prepared to spend.

If you are already in the hands and don't care about the money, the 85 is indeed the first choice, because we all know that this is Canon's portrait king lens.

If you don't have any money, the small spittoon is not a wrong choice, 50mm is one of the three treasures of the poor or you think that the small spittoon is too cheap, you can choose 50mm or 85mm, and it depends on your needs, welcome to ask Continue to answer!

At this price, I recommend the combination of 500D + Sigma 18-200 OS, which is more practical than yours, and the price is just right, so you can think about it. The second 40D set in your configuration is not bad, but the practicality and even imaging have no advantages, so think about it.

It is recommended that you go on 50dand Sigma 17-70

Because these two are compared. The 450D continuous shooting speed is a little slower and the pixels are a little higher. **Cheaper. But the 40D is a mid-range machine after all. But the 40D was the previous generation again, and it has now been discontinued.

First two. The 40d is a notch higher than the 450d.

Don't think about the Sigma head. Canon was originally very meaty, and then Sigma was even more meaty.

In addition, it is recommended to be cautious with Canon, its low-to-mid-range machines, color imaging is not very good.

You can consider the Nikon D90 suite.

2.Canon 40D+ original 17-85 sets.

The 40d is a level higher than the 450d, and the workmanship is much better. 17-85 with stabilization, very practical. The ability of the original Canon head to focus in the dark is much better than that of the counterpart.

18-200 This kind of large zoom imaging is too poor than the lens. The zoom ratio of a lens is inversely proportional to imaging. It's better to have a fixed focus, but it's too inconvenient to use.

7000-8000 budget recommended D90 set.

It's a little better than the four sets above in every way.

If you must enter Canon, it is recommended that the 450D + 17-85is machine does not need to invest too much, because the depreciation is very fast, and the picture quality of the 450D is no worse than that of the 40D.

Support upstairs, you won't regret it on d90, I'm 450d, and now I regret it, it's better to go to 40d.

If you choose among these, you can only choose 17-50.

Because its quality and practicality are relatively balanced, but the focal length is slightly insufficient, but it is enough for daily use;

followed by 18-135, the advantage is that the focal length is large, more practical, suitable for one shot to go around the world, the disadvantage is that the quality of the film is slightly inferior to 17-50, but the image quality can also meet the needs of ordinary people;

The other 2 are not recommended, the 10-20 focal length is too short, and it is very inconvenient to use, unless you only use the wide angle;

The quality of 17-85 is too poor, and the overall quality is not as good as 18-135;

In addition, since the fuselage is 40D, if you are not too short of money, you can also consider choosing the Canon -55, the price is between 4000-5500, and the effect will be better than the above (of course, the photographer's technique is also a big factor).

Only 1 word on 17 50There is a standard zoom, even if it is 18 55 words, 10 20. The family does not need to participate in any activities, that is, the wife travels, and does not want to spend his mind studying this, so 18 135

Sigma's workmanship is relatively poor! After the product has been used for a period of time, the image quality will deteriorate. If you are a CN two body, it is best to choose the original lens, which has good compatibility.

Personally, I prefer to be ultra-wide, and I would like you to recommend a lens, Tokina 11-16

If it's cheap, it's good to have the whole set.,It's not a pity to lose it if it's broken.,Anyway, there's lighting compensation in the room.,Add some money to the whole 15-85 It's not bad.,The picture is very good.,Or it's 17-40.,It's good to use it.。 Personally, for the time being, I want to consider the Sigma 35 for use in the frame cutter, and the appropriate focal length is still large, and the 17-50 can be bought with image stabilization.
