It s no more, please help you. Camera coating issues

Haha, I'm specialized in coating camera lenses, you try to use Ha gas and then wipe it with paper, if it still doesn't work, according to what you said, it should be the highlight of SiO2, and it shouldn't have a big impact on your imaging.

Personally, I don't agree with the opinion upstairs, when the camera leaves the factory, no matter what brand it is, there is a strict visual inspection, from the completion of the coating to the assembly of the finished product and at least 5 times of inspection, if there are bright spots can still flow to the market, this brand is afraid to fall, as for the highlights of SIO2, it is impossible to talk about it, because the landlord said that it is an orange film, which shows that the coated film is now a more popular long-wavelength adjustment film, and more than 80% of this coating is the outermost layer of MGF2At least sony, Nikon's.

I suspect that the highlight of the landlord's camera should be saliva corrosion, talking to the lens when he is not careful, causing acidic saliva to fall on the surface of the lens, and the MGF2 on the surface of the lens is strongly active to acid, causing corrosion. The landlord tries to wipe it off with an organic solvent such as alcohol, using a paper or cloth that is reserved for wiping mirrors or at least a soft paper. If you can't wipe it off, try a crooked trick, apply it vigorously with face oil, and then wipe it clean, which should at least reduce the reflection of these two points.

If it doesn't work, I guess I'll have to do that.

Powershot is basically Canon's entry-level series, and it's generally cheaper than the Ixus.

Canon A3000 1060 Yuan Effective pixels: 10 million Image sensor size: 1 inch Optical zoom: 4x Display size inches Image stabilization performance: Optical image stabilization.

This machine is OK, the cost performance is quite high, if the budget is sufficient, you can consider the following two models:

Canon A3100 1355Yuan Effective pixels: 12.1 million Image sensor size: 1 inch Optical zoom: 4x Display size inches Image stabilization performance: Optical image stabilization.

Canon ixus105 1550 Yuan Effective pixels: 12.1 million Image sensor size: (1 inch Optical zoom: 4x Equivalent to 35mm focal length: 28-112 Display size inches Image stabilization performance: Optical image stabilization.

Just take a look at the professional **.

Canon digital cameras are the best, but they are also more expensive, as the saying goes, you get what you pay for1

I bought ixus and I used it well!!

Panasonic's camera is good, the camera of about 1500 grade is very good, and it is cost-effective. Canon's is also good, but it is a little more expensive, that is, the advertising and publicity are more successful.

The optical quality of the lens should be good; Large magnification zoom is not required.

It is better to have a larger sensor.

The pixel high point is good.

The low-priced Fujifilm has a lot of cost-effective advantages, and I personally recommend that the S1000 is more suitable (the S1500 S2000 is also OK, depending on your budget). This is the smallest telephoto camera, and it is very suitable for girls to hold. The main reason is that 4 batteries are faster to take pictures, the starting speed is also faster, and the number of shots is much better than that of lithium batteries.

Relatively speaking, Fujifilm's consumer DC is still very advantageous. My suggestion:

1. Buy S1000 stand-alone machine in the store "only", about 1300 yuan. (Ask for a bag and a tripod, the total value of a dozen yuan should be able to be sent).

2. Find a store separately to buy four sets of 2300-2500mA sets, "fast charging" (the random purchase must be slow charging, and it will not annoy you for more than ten hours), about 80-90 sets, why two sets of chargers, you can have one unit at home. Buying a battery alone seems to be 50-55 yuan for four sections. The brand is Pinsheng or International Pass.

3. The card recommends a 4g 8g card, and the price is 60 110 yuan. Personally, I recommend 8G card,In addition to taking pictures, you can also save some files without conflict,Fuji's machine video takes up a lot of space,1G is basically more than 15 minutes。 Kodak seems to be able to take more than an hour.

This may need to expand the hard disk.,Anyway, 200g at home is not enough),Don't recommend a random card.,It's generally a 60x card.,It's expensive.。 You just say how many cards you have at home. Come out and buy a card of 133x 200x 233x or c4 c6, recommended brand:

PNY Bienwei, Transcend, Apacer.

4. Card reader: Chuanyu 150x card plastic box (8-10 yuan) has a reading speed of 9m, and 150x soft plastic simple packaging is cheaper 1-2 pieces, and the speed is 2m slower. Except for the original bag sent by the merchant, everything is purchased separately.

It can be much cheaper. You can use the S1000 to set up PK with other machines in the camera channel of Bubble.com, and see what everyone chooses.

1.In fact, the membrane is still very solid and not so fragile.

2.It is recommended to buy a lens pen and wipe it again in a circle from the inside out, it may not be clean.

3.It should be a big mental effect, and it was the same when I first started playing.

It must be your psychological effect The coating is to increase the light transmission of the lens glass The most important role is to prevent the light inside the lens from reflecting back and forth Many lens front group glass can be shot if it is broken, let alone the coating.

Look what you rub it with. In general, a lens pen or lens paper should be used. Using toilet paper or something, it will produce tiny scratches, but wiping it once or twice will definitely not affect the camera imaging, unless you use sandpaper to wipe it repeatedly. So, you're overthinking.

As far as I know, there are only two cases when the lens coating is damaged.

1.Mould (if left in an excessively humid environment for a long time) 2Peeling (if left in a too dry environment for a long time) and the color change of the coating should not be a fault.

I think it might be a problem with the light and angle when you look at the lens, I just tried my lens.

Looking at the past from different angles, sometimes you see green, sometimes you see light yellow.

The coating is relatively a layer that needs to be protected, and the outermost lens is generally not coated, or the outermost lens will have a hard coating, which is differentiated according to the grade of the lens.

You can rest assured that if there is a problem with the coating, you can see it at a glance.

As for the color of the lens, it is generally transparent, a little color, and it is also caused by the dim light or refraction when you look through the lens.

But the problem of coating, I've seen the lens drop the coating, obviously a piece is different from the surroundings, the coating is not so fragile, don't worry, it's okay.

In order to ensure that the camera has good transmittance, the surface of the lens is generally coated with one or several layers of anti-reflection coating, and the first lens is generally reflected green. At the same time, the same batch of lenses will be tested for reliability and carried out under high temperature and humidity conditions, even if you shoot in bright light, it will not have any effect on the lens itself.

As for what you said about not seeing the color, you can see it under the light reflected light, if only part of the range exists, it means that the camera lens film layer is falling off, and the reliability is unqualified.

Recommend Sony TX7C, a search on the Internet knows, Sony's strength is self-evident. The TX9C launched in the second half of the year is also good, supporting 3D, and the pixels are also a little higher than the TX7C. I'm using it pretty well, but the battery isn't very durable.

The lens coating is indeed not so fragile, but it is definitely more delicate than the spectacle lens, or use a special lens cleaning tool to clean it, lens paper, lens pen, blow balloon, hair brush, but it is not a little bit of the lens to toss.

Pay attention to the change from cold to hot from outdoor to indoor in humid environments such as the seaside or in winter.
