This 26x optical Super-Zoom lens has a 35mm equivalent of 26-676mm, making sure that you can capture an image of any subject either near or far. It is made up of 14 elements in 11 groups and includes 4 aspherical and 3 ED elements. To help keep image shake down, Pentax has included sensor-shift image stabilization as well as High ISO digital shake reduction. This long lens retracts completely inside the body to prevent damage when the camera is turned off.

This flash also operates in several modes, including On, Off, Auto, Auto Red-Eye reduction, Forced Red-Eye reduction, Slow Sync, and Slow Sync with Red-Eye reduction.
Normal: Wide up to 30' (ISO Auto) - Tele up to 17' (ISO Auto)
Allowing the X90 to feel more like a dSLR, the EVF (electronic view finder) allows you to shoot without having to look and frame your images using the LCD screen. With 200,000 dots, this EVF will show the same quality image that you will see on the LCD, including all of the shooting information that the LCD can show. Using the EVF is also a great way to extend the battery life of the camera.
The 2.7-inch, 230,000 dot LCD features an anti-glare coating, making it easier to see when shooting outside in bright or direct sunlight. In direct sunlight, the LCD is fairly easy to see, but if you have trouble you can always switch to the EVF.
Controls on Top: On top you can see the Mode Dial, Power switch and Exposure Compensation button on the body. Above those on the hand-grip, are the shutter release with the zoom controls coupled around them.
Controls on Back: At the top you can see the control dial, which is used to change exposure values, depending on what capture mode you are using. In playback mode, it controls the Index and Magnify options. Above the 4-way controller is the Face Recognition and Playback buttons. The 4-way controller lets you navigate menus and select images during playback. In record you press 'Up' to enable self-timer mode, press 'Left' to change flash mode, press 'Right' to change focus mode and press 'Down' to change recording Mode. The OK button in the center accepts user selections. The MENU button calls up and dismisses the menus, and lastly the GREEN button quickly puts the camera into the 'Green' or simple (point-n-shoot) mode, and during in playback it functions as the Delete button.
On the left side of the camera you will find the Input-Output ports, consisting of a PC/AVI port and an HDMI port. The PC/AVI port allows you to transfer images to a computer, or with the included cable, it allows you to play your images on a standard TV. The HDMI port allows you to play your images and HD videos on a HDTV.
The X90 saves its images on any SD/SDHC memory card. With the HD video capture and burst modes, the faster the card, the better performance you will get from the camera. It is shown here with a Lexar Pro 133x, 2GB SD card.
Powering the X90 is a 3.6V, 1250mAh Li-Ion rechargeable battery. This battery is capable of capturing approx. 255 images or 360 minutes of playback time based on CIPA standards, which is a descent improvement over the 200 images that the X70 was capable of capturing.
