The Pentax K-x is another small and compact digital SLR camera, and just like the Olympus-E450 all the buttons and dials are squeezed on the back of the camera, making it very cluttered and untidy and fiddly to use. The control pad gives instant access to the white balance, drive mode, flash adjustments and ISO. Whilst everything is to hand and it is possible to get access to the feature shortcuts whilst framing up and composing the shot it is not a user friendly camera.
The LCD is 2.7 inches and 230K, which is normal for entry level digital SLR cameras, and quite bright. The LCD screen looks large because of the small dimensions of the Pentax K-x, however the screen simply takes up valuable space that could have been used more effectively. This is not a camera for those with big hands or fat finger syndrome.
The Pentax K-x has a 12.4 CMOS sensor, and at 23.6mm x 15.8mm it is slightly bigger than tha of other entry level digital SLR cameras. Despite the slightly larger sensor the image quality produced by the Pentax K-x is not as good as that of the Canon EOS1000D or the Nikon D3100. The internal meter is not as efficient and will require more manual adjustments than using the Canon or the Nikon, which is a big disadvantage for those learning to use a digital SLR camera. The colours produced by the Pentax K-x are not that accurate and there is a tendency to over saturate the colours somewhat.
The Pentax K-x has a burst rate of 4.7 frames per second and a maximum shutter speed of 1/6000 seconds, which for an entry level digital SLR camera is impressive. These features make the Pentax K-x suitable for action photography and other situations where firing off multiple shots in rapid succession is required.
The Pentax K-x has 11 autofocus points, just like the Nikon D3100, which is very good however the Pentax K-x does have a huge flaw in that the focus points are not displayed when looking through the viewfinder therefore you are never entirely sure what you are focusing on. Personally, I think this is ridiculous.
The Pentax K-x has internal image stabilisation via a built in sensor shift, which is very trick. This feature, combined with a lens that also has image stabilisation means that Pentax are doing everything they possibly can to eliminate the dreaded camera shake. The Pentax K-x is supplied with an 18mm – 55mm kit lens, just like many other entry level digital SLR camera, and whilst this is adequate (being better than the lens supplied with the Olympus E-450 and Canon EOS1000D but not as good as the lens supplied with the Nikon D3100) for capturing good images and learning with you will soon find yourself wanting to upgrade.
The Pentax K-x has the additional feature of HD video capture at 720p and 24 frames per second. Whilst this is not as impressive as the Nikon D3100, it is still a nice feature and considering other entry level digital SLR cameras don’t have video capture, very welcome.
The build quality of the Pentax K-x can only be described as average. It is not really durable nor is it poor, it’s just middle road and if you look after it the camera should provide many months of trouble free use.
The Pentax K-x does not have its own internal battery, unlike other entry level digital SLR cameras. Instead, the Pentax K-x operates on four AA batteries. In some respects this is good as AA batteries are readily available, however the downside of this is that over the life of the camera it is going to work out very expensive, so this needs to be considered before making the decision to purchase this camera.
The Pentax K-x is one of the more expensive entry level digital SLR cameras on the market, and whilst it boasts a reasonably large 12.4Mp sensor, internal image stabilisation, an impressive 4.7 frame per second burst rate and video capture there are many niggling things to consider. The Pentax K-x camera is a reasonable contender within the entry level digital SLR category however it is not one I would recommend as the negatives outweigh the positives and there are better alternatives out there, such as the Canon EOS1000D and the Nikon D3100.
