Why is the 450d so popular and not buying the km or k20d

1. Because Pentax's commercial market is doing well and the publicity is in place, Canon has a higher status in people's minds.

4. Canon's market is bigger, you can buy Xiaobai everywhere, but can you buy Pentax's 80-200 everywhere?

5. Canon's lens is cheap, Pentax's body is not expensive, but the lens is expensive.

6. Canon's high-end equipment can drive the market, while Pentax does not have high-end equipment at all, and the current state is stormy, and it is impossible to say that it will be gone one day.

Two points: 1. The original lens group NB, the telephoto is particularly prominent;

2. The EF mount flange has a short focal length, which is convenient for transferring to more NB lenses.

Therefore, Canon has become the first choice for equipment photography enthusiasts and DSLR bodies.

So Canon has a large user base;

Therefore, Canon users say that they can change their heads, unlike other homes that have to think about it for a long time and then buy a new one, and the old ones have to worry about whether they will sell at a loss;

So ......You won't find a telephoto head that surpasses the Canon in autofocus speed.

You want to compare the phase, you don't think about the structure? You have to think about the structure, can you not transfer?

At present, if you want to transfer, the EOS body is definitely the first choice.

The 450D does have a whole bunch of shortcomings that you mentioned, but it's stained with Canon's light.

I also think that 450d is garbage, I now use sonya200, very good, I think 450d is Canon's brand, specializing in deceiving superstitious brands for nothing.

I support Pentax, but Canon is not against it either, I have a few film SLRs that are PK-mouthed, Pentax head can be described as a knife cut inside the burn, and the cream outside the burn is good.

Turnips and cabbage have their own loves.

Pentax's K20D is a good mid-range machine, with a higher grade than the 450D. And Canon's EOS 450D should be considered an entry-level model. Both machines have their own merits.

The benefit of Pentax is that there is in-body stabilization, even if you use any lens, it is equivalent to having stabilization. Personally, I am very optimistic about the Pentax camera and like its mount because it can use many old lenses with PK mounts on the market. At the same time, I am not very satisfied with Pentax's lens group, one is that there are fewer lenses, and the other is too expensive, like the three princesses, the bull head is even higher than the Canon lens of the same specification, and the lens is small, and it does not look powerful.

The good thing about Canon is that there are many people who use it, and there are all kinds of lenses of various grades, so there is a lot of room for choice. In addition, Canon's mount also has the advantage of using a variety of old lenses on the market through an adapter ring. It's just that there is no body stabilization, and if you want to stabilize the image, you must buy a special stabilization (IS) lens.

If it is these two machines, it is recommended that you do not buy 1855 sets, it is a waste of this body.

You can consider 450D 18-135, which is basically enough.

1 Of course, 20D is good, positioning is different, km is the entry model, 20D is the mid-range model, not just pixel differences.

2 Any camera is out of focus, and the wider the aperture, the easier it is to get out of focus.

3 Manual focus is a lens function, and it is okay, regardless of the body.

K20D is a mid-range machine,The biggest difference with KM is that there are more focus points,With fuselage motor,And pixels, etc., are not explained one by one,In short, I want to buy wide-angle Pentax,K20+16-45 head,Yes,That's what I use,There are a lot of improvements compared to K10,! If you just play around, you don't need to buy K20, you don't even need to buy a DSLR, if you want to do photography, then you want to throw it away if you buy KM! See ,—— Note:

I'm a photographer. I care if you give me extra points, but I hope you will take my advice and choose between KM and K20! (SLR is very expensive, so you need to be cautious when getting started).

As a K20D user, I am very satisfied with my machine, Pentax is a very good value for money machine, if you have enough money, it goes without saying buy the best you can afford. There is a guy above who is right: there is no need to buy a DSLR to play casually, and you will feel that it is not enough after you get started with the entry machine.

However, the K20D has been discontinued, and Pentax only produces the K-M and the high-end K7, so it is a hassle to buy it.

The 450D is the more expensive model of Canon's DSLR's entry-level cameras. Pentax K20D is the top-of-the-line version of its brand, which is equivalent to the mid-range camera of Canon Nikon's top-of-the-line brand.

Whether you buy a beginner, intermediate or professional DSLR, Canon and Nikon are generally recommended. In the first half of 2008, the market share of SLRs in Japan can be found at: Nikon, Canon, then Sony, Pentax and Olympus are not above 8%.

Not at all on a level.

The K20D is a notch higher overall.

It is also more functional, and the performance of the K20D is better than that of course.

Not a level thing, Canon counts as entry-level, while Pentax counts as mid-range. If you have money, you will naturally buy it, but the price difference between these two cameras is not small, I don't know why the landlord will be compared.

Basically 2 notches worse.

The 450D can only be compared to the K200D.

The 450d is better than km in the brand Canon. So there are more choices of lenses. You can also go to full width in the future.

Pentax does not have a full-frame SLR, and it seems that there will be no at present, so it can only use APS machines in the future.

If you talk about the machine alone, there is not much difference.

The 450D shoots like some gray, the km shoots more colorful than the 450d, and the km set of the camera has better imaging than the 450d.

Pentax's words suggest that the landlord go to K200Dha,Body stabilization is one of Pentax's relative Canon advantages,That is to say, all lenses become anti-shake after installation。 Unlike Nikon and Canon, the same lens can be thousands of dollars different from having no stabilization**.

In addition, Pentax's advantage is that the lens coating technology is the best on the market, so the anti-glare and ghosting of its lens are the best. But Pentax's older lenses are slower to focus. The waterproof performance is relatively good.

Canon's advantage is that there are more products and there are full frames. The lens focuses quickly.

In terms of lens lines, Pentax is cheaper for zoom and more expensive for prime focus.

The Canon has cheap large-aperture prime focus, but the zoom L-head is expensive.

First of all, their biggest difference is the difference in imaging style:

Canon imaging colors are conservative, more elegant and realistic, and trade low contrast for more detail. Pentax is very different, the colors are bright and saturated, and the colors can be said to be very strong, a little more intense than Nikon's. Therefore, Canon is still good at shooting portraits, and Bincan has the advantage of shooting landscapes.

Second, in terms of the scientific and technological gold content of the fuselage, Canon is stubbornly better than Pentax. In the Canon body, it always occupies the latest technology in the same class of cameras, and its performance indicators are better than its opponents in all aspects, compared to Nikon and Pentax, which are relatively conservative. But Pentax also has its own advantages, such as the Pentax body has a CCD anti-shake function, using the body as an anti-shake, and any lens is stabilized, which can save a lot of money for additional anti-shake lenses.

Thirdly, I have to say the difference between the two brands, the Canon EOS series is now an EF mount lens, and there is no longer an aperture ring on the lens, and the aperture is completely driven by the built-in motor of the lens. In addition, the EF mount of the current EOS camera does not support the old FD mount at all. Nikon and Pentax are different, they retain the structure of the aperture rod of the fuselage driving lens, and the lens mount has been used to this day, so for Nikon and Pentax users, they can use more old lenses in their hands, using the classic manual lenses of the early years, and Canon's compatibility with old lenses is basically equal to zero.

In the end, both machines are actually at the entry-level level, especially today, both of which are outdated. As for which one is better, it really means that each has its own advantages and disadvantages, regardless of the different styles, as far as today's point is concerned, it may be more advantageous to just talk about the technology 450d; However, if you like to play with old shots, Pentax is more suitable.

Above, I don't know if you are satisfied?

By the way, in addition, I have used these two machines, when using Pentax, 18-55 knocked slightly, the lens bayonet ring was broken, and I checked it on the Internet, and there were many people who had the same experience. If you want to use Pentax 18-55, it is recommended to buy a metal bayonet!

450D is not much better than km, but Canon is much better than Pentax in the field of 35mm DSLR as a whole, so if you want to play, you must choose 450D, as for the lens group and maintenance, it must be Canon, and it is not much cheaper or even more expensive to buy back in Hong Kong, and it is troublesome after sale. It's still 450d at this price, unless you definitely don't play it in the future, but it's hard to say.

The fatal thing about Pentax is the poor workmanship of its 18-55 sleeves. In addition, it supports very few lenses, which is not conducive to future upgrades.

Of course, the 450D's 18-55 jumper is not good enough.

In general, Pentax's dual-lens set is basically in place in one step, about 4100. And Canon will burn money if it upgrades the lens in the future.

The Canon is better than Pentax in that it focuses faster, but when it comes to landscapes, Pentax is better (for the average person's appreciative eye).

Dude, let's tell you about this base, Pentax's machine is cost-effective, that's not to say, and the head is not a dog, it's definitely enough. KM and K20D are not the same grade, I personally highly recommend you to choose K20D, and you will know when you talk about it. Since you want to buy a DSLR, it means that you still have a certain understanding of photography, if you buy km, I believe that it is only half a year, you will think it can not meet your requirements, so K20D is your best choice, you think about it!

In addition, if you have a limited budget, you can also consider the Olympus E520, which has a higher level of stability, and the anti-shake effect of the Aojia's body is better than that of Pentax and Sony.

Purely in terms of image quality, K10D is better, because it is CCD imaging, but in a cloudy day, CCD's performance is not as good as CMOS. In terms of high sensibility, it must be K5 is more dominant, ISO3200 is basically noise-free, very strong. With lenses, mainly according to the budget, Pentax's several prime heads are still relatively powerful, the imaging of the three princesses and three biscuits is very good, the zoom head is the first choice da*50-135, very toxic!

If you change the door, the 5D2 is the most economical entry-level full set, with a red circle head, the imaging is very good.
