I received this camera last Friday. I had 2 full days to take great shots with this camera. I purchased two bundle kit, which comes with 18-55mm lens as well as 50-200mm lens. I have another manual focus lens, which is A50.7.

One of the most asked questions about this camera is AF speed. Yes, AF is pretty quick. To test AF speed, I sometimes turn focus ring to opposite direction and checked the time it takes to set the focus. It was usually less than 0.4s. Even in low light situation, it worked fine. I took many shots with only one small table light in the living room so, ISO was 6400 and shutter speed was 1/4. Camera doesn't seem to have any problem for AF. Nice thing as a entry level camera is that it supports up to 11 AF point and you can choose your AF point. Some may say, it lacks super impose. However, simply touching 'ok' button reveals current AF point in the LCD screen. So, that's not a problem. AF is sharp and accurate. In MF mode, camera indicates the right focus in two ways both sound and indicator. So, there's no problem using manual focus lens. in Liveview mode, Camera magnifies focus point to assist you, which is very useful since viewfinder is very small.

High ISO support. This is the best part I like about this camera. It supports up to 6400, and can be expanded to 12800. I took several shots outside around 6:00 PM. My friends used flash but my K-x didn't require flash. with 3200 or 6400 ISO, it still gave me clean bright pictures. Pentax did a great job reducing noise, especially color noise. It's hard to find the noise from the pictures. Now, 3200 is something you can use everyday. Actually, scene mode for the kids uses very high ISO to get 1/1000s or faster shutter speed. Thanks to that, pictures for my kids are all sharp and crispy.

Verified Purchase
Pentax Kx is Pentax digital SLR for beginner and enthusiast. Pentax Kx replaces Pentax KM / K2000. There are many improvements from KM, such as three stops higher ISO setting, video recording, faster continuous shooting, 11 selectable auto focus points and 12.3 megapixel image resolution (compare to 10 mp). Kx shares same body as Km, so it is still very compact but not weather-sealed like Pentax k200, k20d or k7. It also use four AA batteries instead of lithium batteries.


Pentax Kx weights 581g, and its dimension is 122 x 92 x 69 mm. It is one of the smallest DSLR camera around, but not the lightest because of body material and 4X AA batteries.

Using batteries has been always been debated, some people like to have lithium battery with their camera, especially those who does not or concern about reliability of rechargeable batteries. Some might prefer the universal AA batteries because they are available everywhere and the rechargeable one is relatively cheaper compare to lithium one.

Built quality of this camera is generally good for beginner digital SLR, sturdy and substantial. Ergonomic is not the best especially for people that has big hand or finger, but it is good in general.

Like KM, the camera interface has been simplified yet very accessible. It has one thumb dial which you will use this a lot to change setting values. There are dedicated trash button, AF/AE-L, exposure compensation button, customizabe green button, live view button, info button, four way buttons which are shared with ISO, WB, Flash, self timer. These are basically what you will need and expect from a good digital SLR camera.

There is also a shooting mode dial, where you can find manual and semi automatic control.

43 of 44 people found the following review helpful By W. Struth on December 5, 2009
I purchased the K-X with the two lens kit with the 18-55 lens and the 55-300 lens.

This is a wonderful little camera; the autofocus is fast and accurate, the menus are clear and easy to use, the picture modes let you play with your creativity or you can use it for just point and shoot, and it has manual control when you are ready to use it. I went with the long lens because I take a lot of detail shots and this lens does the trick for me. I haven't yet found a situation where I needed to zoom in closer, and when I do I can always buy a longer lens. Back to size it's a great one handed camera to use, I find the camera comfortable to handle and it feels well made.

I've taken about an hour of video so far; it can shoot up to 25 minutes of video at a time. It's not a video camera but when you want to take a video spontaneously it works great. For me the video is just icing on the cake. The photos are what I bought the camera for. I use mostly the aperture priority (to manipulate the depth of field or get low light shots) and the auto picture settings. And they come out consistently crisp and accurate. Sometimes you will have to manipulate the white balance settings especially when you use the low light capabilities of this camera without a flash, as with any DSLR. The camera has lots of digital filters to process your pictures with, and they are fun to use. What I love most is being able to use the high ISO settings and not need a flash indoors and still get great quality shots.

I use rechargeable batteries in the camera and have now downloaded the new firmware so the camera recognizes them faster. This is a must do because before I had to turn the camera on and off and turn the live view on and off for it to recognize new batteries.
