Pentax K-S1 Overview

  • 1Description

Incorporating stylish design elements such as LED indicator lights on the grip and lighted camera controls, the black Pentax K-S1 DSLR Camera with 18-55mm Lens provides users with a compact, intuitive camera kit. At the core of the K-S1's performance is a 20-megapixel APS-C CMOS sensor and the PRIME M II Image Processing Engine which enables the capture of highly detailed images with accurate color rendition at ISO speeds up to 51200.

Inside the camera body is a variety of technologies, including a sensor-shift Shake Reduction system for capturing sharp images in less than ideal shooting conditions. The sensor also lacks an anti-aliasing filter, but can be put into a simulation mode that will recreate the effects of one for use in certain situations.

The K-S1 is very responsive with the SAFOX IXi+ 11-point autofocus sensor and the ability to capture 5.4 frames per second. This system also features 9 cross-type points in the center for increased performance. Along with fast focusing, the camera can record full HD 1080p video at up to 30 fps. This video, along with photo review and settings, is seen on the bright 3.0" 921k-dot TFT LCD monitor.

Additional features of the K-S1 include in-body RAW file development and HDR shooting. Also, there are enhanced creative modes and filters for giving a unique look to your shots. The camera records all these images to SD cards and is compatible with both Eye-Fi and FLU cards for adding more capabilities to the camera.

Bundled with the K-S1 is the smc PENTAX-DA L 18-55mm f/3.5-5.6 AL Lens. This lens provides users with a versatile 27-82.5mm equivalent in 35mm format. Also, the 18-55mm features a lens construction of 11 elements in 8 groups and utilizes 6 diaphragm blades for natural out-of-focus areas.

20MP APS-C CMOS Sensor and PRIME M II Image Processor
The combination of the 20-megapixel APS-C CMOS sensor and PRIME M II image processor is able to produce high resolution imagery with notable quality and low-light sensitivity to ISO 51200. The speed afforded by the image processor enables continuous full-resolution shooting up to 5.4 fps, a maximum shutter speed of 1/6000th of a second, and also supports full HD 1080p video capture.
SAFOX IXi+ Autofocus System
The SAFOX IXi+ AF system utilizes 11 focus points, including nine cross-type sensors, to quickly and accurately acquire focus using a phase-detection method. With the inclusion of an AF-assist lamp and a diffraction lens, precise focusing is possible in a wide variety of lighting conditions using single-shot or continuous focusing modes. This system also features a sensitivity range of -1 to 18 EV at ISO 100.
In-Camera Shake Reduction Image Stabilization
The Pentax sensor-shift type shake reduction image stabilization helps to minimize the appearance of camera shake when working with longer lenses in dim lighting conditions by up to the equivalent of three to four shutter speed steps. This helps to produce sharper overall imagery regardless of the lens in use.
Full HD 1080p Video
In addition to high quality still imagery, the K-S1 also supports full HD video recording up to 1080p at 30 fps. Other frame rates available include 1080p at 24 fps and HD 720p at 60, 50, 30, 25, and 24 fps. Video is recorded in the high quality H.264 AVC/MPEG-4 format and can be saved in the Internet-friendly .MOV file format. Sound can be recorded along with the video using the built-in monaural microphone.
smc PENTAX-DA L 18-55mm f/3.5-5.6 AL Lens
The included standard zoom lens provides a 35mm-equivalent focal length range of 27.0-82.5mm to suit working in a wide variety of shooting scenarios. It features an SP coating to help repel dust, water, and grease on lens elements and a lightweight design to promote greater portability and use during travel. Its construction incorporates aspherical lens elements to help minimize chromatic aberrations throughout the zoom range and also contribute to producing overall sharper, clearer imagery.
Other Camera Features
  • A 3.0" 921k-dot LCD monitor is available for live view monitoring, image playback, and menu navigation.
  • Pentax K lens mount enables the use of a wide variety of both past and present K-mount lenses as well as compatibility with a variety of lens mount adapters.
  • Enhanced creative modes, scene modes, filters, and auto picture modes allow you to easily modify and adjust the overall aesthetic appearance of imagery in-camera.
  • Eye-Fi and FLU memory card compatibility for wirelessly transferring imagery directly from the camera and adjusting settings remotely.
  • Built-in pop-up flash with a guide no. of 32.8' at ISO 100 provides additional illumination for low-light settings and covers focal lengths as wide as 28mm.
  • RAW image processing is available in camera in order to quickly and easily convert images an Internet-friendly JPEG file format.
  • In-camera HDR shooting works to effectively expand the dynamic range of an image and achieve greater shadow and highlight detail.

Pentax K-S1 Reviews

K-S1 DSLR Camera with 18-55mm Lens (Black) is rated 4.7 out of 5 by 10.
Rated 5 out of 5 by from Great compact DSLR I'm blown away with this camera. I have the K-3, K-5 IIs and K-01, and this will become my default body for all but my commercial live music photography. It's small, it's light, and the button placement is a work of genius - all the essential controls just fall to hand and the others are out of the way. There is something special about the image quality too - almost like the old CCD sensor of the K10D. Traditionalists don't like the styling, or the LED's, but for me it's all about taking photographs, and this camera is a serious shooter.

Rated 5 out of 5 by from durable Took great quality photos. I still have a lot to learn about my camera and the best way to do that is to use it. I have been shopping in the area for a new camera and this was a reasonable camera price. Everywhere else was selling this for an expensive price. The Price was reasonable and right. Thank you B&H for such an affordable camera. I will update my review with photos that I took.

Rated 4 out of 5 by from A very nice camera at a budget price. This is our first digital camera (besides the iPad) and it is working out nicely. It's light and svelt compared to many other cameras. It does take a bit of effort to learn all the features and have them second nature while using it, but it's no more than most digital SLRs out there today. Highly recommended for the casual photographer: landscapes, portraits and family gatherings, mainly for imaging artwork as in my case. Also, I am able to use my 30 year old bayonet Pentax lenses in manual focus and aperture mode. Yeah!

Thank you B&H photo for making this camera affordable.

Rated 3 out of 5 by from Almost a winner! Spent hours researching this category. Feature-wise, the Pentax K-S1 came out on top for me and beat the competition hands-down, BUT upon receiving it, I found it difficult to hold.....awkward and uncomfortable. Returned!
