Pentax KX wants a wide aperture, blurred background, and usually shoots landscape portraits, student

If you shoot portraits, you can choose a 50 fixed focus, the aperture is large enough, and the depth of field is relatively shallow.

If you shoot landscapes, buy a wide-angle, similar to Canon's 17-40 It's enough and cheap.

The method you send ** is to adjust the camera to MF (manual mode), then adjust the aperture to the maximum, focus manually, and then press the shutter directly to bring up this effect.

Taking into account both landscape portraits, of course, the focal length is between 15 and 135, and the more mainstream focal length is -70......

If the focal length is selected, then it is the aperture, and the aperture should be as large as possible, which can basically meet the requirements of depth of field (bokeh background).

Then look at the imaging quality, the performance of large apertures.

Finally, you look at the economy, I got on the second princess and da55 to shoot portraits (now think about it, it's better to go directly to the fa85, interested in 55 or da70 I can transfer), into a zeiss 35 and 180 to play manual, da14 to shoot landscapes, super telephoto into a 400, anyway, I'm a toss. Finally, I hope it helps you.

Get a 17-55 head aperture. Practical head. ** In 2000 so. Take a portrait of the landscape, and the students will choose.

It's not an aperture, you use MF to block it, and it's OK to put the focus point to the nearest one.

There is no focus on the top.

If you need a bokeh, buy a Sigma.

Pentax's original 35 and DA40 are quite cost-effective!

It is recommended that you buy the KX large double set, which has a super cost-effective telephoto 55-300Then have the bull's head in the dog's head 18-55!

For shooting buildings, you can use 18-55 for landscapes, the wide angle is still good, and you can use 55-70 focal lengths in 55-300 for portraits. Then you can pat the moon, the bedroom on the opposite floor. After you play for half a year, you decide where your lens will go.

KX large double set is also nearly 5000, small double set is only 4000 early days, all kinds of things, batteries, bags, memory cards, etc. will cost you nearly 400 yuan, if the budget is really limited, you can buy KX set first, set of about 3300, all good on about 3700, or very cost-effective! However, it is not recommended to buy a small double set.

Of course, if you are not in a hurry, you can buy kr after three months to half a year, and it may be cheaper at that time, and I estimate that your budget will be higher.

The upstairs selection is very expensive, and the Pentax 50 header is very expensive.

It is recommended that the official double-ended set of machines, 55 200 can take portraits.

If the wide-angle end of the lens is multiplied by the magnification, it is less than or equal to about 24mm, and the portrait is on the 50 header.

This problem, presumably, is due to two reasons:

1.The reflector is dusty. If you believe in your craft, you can take an air blow reflector, but be careful in a dusty environment.

Otherwise, you will blow more and more, and it will be more troublesome to get coms dust. At the same time, be sure not to wipe your reflector with a cloth or anything like that, because many people just won't, so the more you rub it, the more it will only cause more damage!

2.The focus screen is dusty. This one is Pentax not sealed enough.

If that's the problem. Okay, congratulations. There's nothing you can do as a newbie.

Of course, if you dare to do so, you can remove the focus screen and wash it yourself, there are many tutorials on the Internet. However, this is a bit risky, and it has to be based on absolute confidence in your craft, otherwise you will understand it yourself.

The above two questions have no effect on your camera imaging, and will only bring great annoyance to your pursuit of perfection My advice:

A, forget it, it's not painful, bear with it.

b, ri, do your own shop it

c, give a little money and let the person who repairs the camera do the trick. --This is a little safer for novices, so let's do it yourself.

If there is also one on the **, it is estimated that the dust is on the photoreceptor. Try the machine's automatic cleaning function. Or turn the camera to the bulb and blow it with a leather blow.

1. The larger the aperture, the more blurred the background. 18-55 lens, 55mm maximum aperture is where you use this.

2. The closer the subject distance, the more virtual the background. You should be closer to the subject. It's not okay to get too close, otherwise you won't be able to focus.

3. The longer the focal length, the more virtual the background, as the saying goes: the aperture is not enough, and the telephoto comes to make up. 55mm is the longest focal length, with this.

4. The farther away the subject is from the background behind you, the more blurred it becomes. In addition, I am also a KX user. KX Pullover 18-55 The two ends of Zheng Hanfeng's widest shout are not very good, and the best focal length is between 24-45.

This range is generally recommended. Because you see that your lens is shortest at 35mm focal length. Twist the lens to 18mm and 55mm to make it longer.

The longest time will have an impact on the image quality, 18-55 lens, based on 35, there will be errors in one variant. This can be explained why the prime image quality is strong and the zoom is always filial piety.
