Pentax K-S1 Introduction: A compact design in 12 different colors

The first D-SLR features a flashing LED on the handgrap, along with illuminated controls on the rear, the new K-S1 is Pentax’s latest entry-level offering. Aimed at consumers moving from compact or bridge cameras to DSLR photography, the Pentax K-S1 is a small compact body design available in 12 colors, including black, white or orange.

All designs have the same green LED, so unfortunately there is no color coordination with the flashing lights. The K-S1’s kit lens is only available in black, so if you’re not careful, you might end up with a flashing, multi-color camera.

Breaking Pentax with a full frame sensor is yet another option featuring the K-S1 APS-C CMOS chip. However it is a newly developed sensor, which packs a 20.1Mp resolution which sandwiches it between the existing Pentax 24Mp K-3 and 16Mp K-5 II models.

Like the K-3, the K-S1 sensor features Pentax’s innovative anti-aliasing filter simulator with 3 modes to control the amount of smoothness applied to images. This is an interesting feature that makes the K-S1 a bit more versatile, but slightly redundant on entry-level DSLRs and probably better for mid-range models.

Unlike many Pentax DSLRs, the K-S1 small body is not weather-sealed against the elements. However it has Pentax’s camera feature Sensor Shift ‘shake reduction system, which provides image stabilization with almost all Pentax K-AF2 mount lenses.

 Priced at just $ 747 body, or $ 797 including the standard 18-55mm kit lens, the K-S1 is slightly more expensive than the main Nikon and Canon entry-level offerings from the competition, and older Pentax DSLRs such as the K-5S, too .

Pentax K-S1 sensor measurement: a slight regression to the Pentax sensor score
Pentax ranks 62nd for all sensors on the K-S1 database and 30th for APS-C sensors with a DxOMark sensor score of 78.

It ranks 9th for Pentax APS-C sensors behind older, lower resolution models such as the Pentax K-5C, as well as higher resolution Pentax sensors like the K-3.

Having said that, the K-S1’s overall score is 78 places, just 6 points behind the APS-C sensor’s leading class in the Nikon D5200, which, with 84 points, provides 1 / 3rd stops overall, better image quality. .

In terms of the 3 sub-scores that feed into the overall score, the K-S1 performs marginally better for the dynamic range, with the 13Evs ranking at 26th for all APS-C sensors tested. Pentax has historically scored well for dynamic range, giving them a good APS-C option for landscape and photography in broadly mild conditions.

In fact the Pentax K-5 II remains the leading pioneer APS-C sensor for dynamic range measurement, providing a 1 stop improvement over the K-S1, with a score of 14.1Evs, despite it being the strongest aspect of the new model is. .

 The K-S1 score of 23.5 bits ranks 64th for color depth and the low-light ISO measurement of 1061 ranks K-S1 at 61st, both consistent with its overall performance.

Pentax K-S1 vs Canon EOS 1200D vs Nikon D3300: Tough entry level competition from Nikon

So how does the new K-S1 compare to entry-level options from the larger Nikon and Canon competition? Well, with its body price tag of only $ 747, the K-S1 is currently more expensive than the $ 547 Nikon D3300 and the $ 699 Canon EOS 1200D, both of which have been on the market for a long time.

In terms of features, the K-S1’s anti-aliasing filter simulator is unique and Pentax also offers a wider ISO range, built-in sensor shift and a faster / 6000th maximum shutter speed. The D3300 boasts the highest resolution at 24Mp and the best DxOMark sensor score to boot.

With a DxOMark sensor score of 82, the Nikon D3300 provides 1 / 3rd of a better stop image than the K-S1 with 78 points.

There is nothing between them for the dynamic range, with a score of 13 EVs compared to 12.8 EVs.

The D3300 offers 1 / 3rd of Stop Death Color Depth, scoring 24.3 bits compared to 23.5 bits for the K-S1 and is also a strong point for the Nikon D3300 with its score of 1385 ISO on the way to the APS-C. Sensor.

 This equates to about 1 / 3rd stop of an improved performance compared to the K-S1 with a score of 1061 ISO, which is a great result considering the D3300’s features on a high resolution 24Mp sensor.

However the K-S1 is better than Canon’s 1200D entry-level DSLR. With its overall score of 78 compared to 63 for Canon we can say that the K-S1 offers 1 better image quality than the EOS 1200D.

Dynamic range as we have seen is often a strong point for Pentax and the K-S1 offers against the 1200D almost halting outperformance with a score of 13 EVs versus 11.3 EVs.

This difference is not dramatic for color depth and ISO, but again the K-S1 turns out favorably in both ranges, providing about 1 stop better color and a better ISO performance on the EOS 1200D. Pentax K-S1 vs K-3 vs K-5 II: Different resolution, same sensor score

If we compare the new K-S1 score to other Pentax DSLR models, we can see that the overall image quality is roughly the same, with the highest scoring 24Mp K-5 II just 4 points and the stop better image. Compared to 1 / 3rd overall, the K-S1.

Now available at discounted prices around $ 697, the K-5 II is slightly cheaper than the K-S1, but offers a fairly similar feature. The main difference is the K-5 II’s lower resolution 16.4Mp sensor, but despite this it still boasts the best Pentax sensor scores in almost all categories, bar ISOs where it is outscored by the K-3 only.

The K-3 definitely packs an additional 4Mp resolution at 20.1Mp K-S1 and gets marginally better scores in all sub-categories than the new model. What with its weather-sealed body and faster frame rate K-3 is higher than the K-S1, but it is more expensive at $ 1,347 compared to $ 797 for the K-S1.
