Is Canon 50 1 8 good at running focus?

I think some people may say that the out-of-focus is just a problem of use, because when using the maximum aperture, the depth of field is very small and difficult to control, so when you don't master it well, focusing errors often occur, and it is often found that the focus is not in the desired place after shooting. To avoid this problem, one is to practice more, and the other is not to use the maximum aperture when it is not necessary.

However, because this lens does not use an ultrasonic motor, the focusing sound is really loud, and the focusing speed is relatively slow.

After all, the price is here, and you can't ask for too much, so this lens is called one of the "three treasures of the poor".

The method of center focus and reshift is best not used in scenes where the focus point and center are too far off.

This is determined by the different angular optical characteristics of the lens group.

This one depends on how much you run.

It's best to take the focus reference** and print it out to shoot it quantitatively.

If it is a slight out-of-focus, the repair point may not recognize it.

Everyone has their own habits, and which of your focusing methods is traditional. The other focus is moving, which is used quickly and accurately.

A lot of it is an operational and technical problem. Nothing to do with the lens.

The 50D body should be equipped with at least 50.

You don't even know what it means to run out of focus.

There are two kinds of defocusing, one is that the focus is off a little, and the other is defocused, ** the whole blur. The former can only be fine-tuned by a camera with a fine-tuning function, or sent to a repair center for adjustment. The latter is a common problem with large-aperture lenses, the lower the probability of a good lens being out of focus, and the success rate of more than 50 can produce a film is only 50%, and 50 should be much better.

But there will be, and the only way to do this is to take two more shots or reduce the aperture. The wider the aperture, the easier it is to run. Adopt it.

The Canon 50 is out of focus as follows:

1. The large aperture is seriously out of focus, and the small aperture has no problem of out of focus.

The aperture is small, and it is basically not out of focus.

However, when the aperture is larger, the out-of-focus is very severe.

2. Focus.

With ** point focus, there is very little defocusing.

Focus with the points on both sides, and it is easy to get out of focus.

Outdoor 85 is better, the background blur is perfect.

100 is also available.

50 is not recommended, this is more suitable for small indoor scenes.

100 is still good for taking flowers, and portraits are still good for 85.

The Canon 50 is an excellent large-aperture prime lens, and it's worth buying for portraits.

1. Lightweight, simple but reliable structure;

2. It's absolutely no problem to shoot portraits with aperture, the sharpness at the beginning of the above is very good, and at the beginning, it looks like it has reached the optimal state with the naked eye, which can be said to be unstoppable!

3. Although the color is not rich, it is ten true, giving people a refreshing feeling, and the optical system is absolutely "standard";

4. Although the autofocus sound is slightly louder than that of the ring motor, it is very fast;

The original factory is not recommended to buy, and now the Sigma Canon mouth on the market is very cost-effective, not less than the original head, and ** can be bought at 2150. The imaging and color are very good and are also used by many professional photographers.

This one is okay at home, but it's very old, and it's more suitable for a half-width machine.

You might as well be able to go to full frame in the future.

The Canon 50 lens has good performance, but it is not very high, and it is very cost-effective. It is worth buying for users who need this type of lens.

The Canon 50 lens is a mid-focal length and large-aperture prime lens.

From a focal length perspective, this lens is suitable for portraits.

At the same time, the lens has a wide aperture, which can achieve good background and foreground bokeh effects, making it easier to highlight the subject when shooting portraits, and shoot well-layered works.

In addition, the ** of this lens is very low, so it is a typical lens with not low performance, but not high, and it is very cost-effective, known as one of the "three treasures ......of the poor".

Therefore, for users whose situation matches the condition of this lens, this lens is definitely worth buying.

However, this lens is not flawless.

First of all, the workmanship and materials of this lens are average. This is determined by its positioning......Because the positioning is not high, its production cost must be relatively low, so its workmanship materials are generally ......For users who are looking for high-end lenses, this lens is not worth buying.

Secondly, the relatively general workmanship and materials determine that the image quality of this lens is also relatively ......Of course, from an absolute point of view, the image quality of this lens is still good. However, compared with high-end lenses, there is a real gap in image quality, especially the bokeh effect is average.

Therefore, whether this lens is worth starting depends on the user's needs ......

1. As long as it is a large-aperture lens, it will be easy to get out of focus, no matter which one.

Second, many times the shooting is not good because of the technical problem, and it has nothing to do with the focus of the aperture, because the depth of field is very shallow when the aperture is large, as long as you shake the focus with your hand and run to another place... And the shallow depth of field makes it easy to see that the focus is shifting...

3. There are absolutely no 10 cards, only 1 can be used with such an exaggeration.

Fourth, the lens is generally very fleshy at the maximum aperture, and it is necessary to reduce the aperture by two stops to use five, "I don't know if it is my RP burst The lens I have used has never encountered a defocus From 17-40 70-200 This red circle to 18-55 18-200 (Sigma's) 50 is not out of focus It feels good Friends around me have not heard of anyone's lens out of focus It seems that the current focusing technology is relatively mature The problem of out of focus is not so serious".

You listed a bunch of lenses with small apertures... I've never heard of a small aperture lens going out of focus... Large depth of field... You can't see it when you run...

I bought a small spittoon in December 08, and it has never been out of focus, but it is difficult to focus in a poorly lit place, and the bellows will! As for what you said about 10 out of one, it's nonsense, don't listen to other people's nonsense! I can guarantee that the person who said this is someone who has never used a small spittoon!

If you're worried, try a second-hand spittoon! At least I think it's definitely worth having, a civilian cost-effective fixed focus!

Buy it with confidence, in the 350D-20D era, running the focus is a hot topic.

Portraits? That's absolutely fine!

**Within 3000! The imaging is okay! Once the aperture is received at 2, it is fine.

Of course, it also depends on the camera you use.

If you want to shoot daily, at least 18-55 is equipped, and sometimes you need a wide angle in a narrow room. The last second-hand one is not expensive, 500 yuan. A lot of times it can be saved.

Portraits are also more suitable for fixed focus, and it is difficult for the zoom head to have a beautiful background illusion effect no matter what focal length.

The use of fixed focus and zoom, many situations need to get used to, the fixed focus must be moved back and forth by the photographer, the zoom is not needed, just get used to it, no problem.

However, if you have 50 money, it is recommended that the landlord consider 85, which is a good head.

The Canon 50 has a good fixed focus, but it is not high, but it is easy to run out of focus, so you should pay attention when buying.

Lack is not very satisfied. I want to get one.
