Low light photography? Affordable? Look no further!

27 Jan

Ricoh just took the wraps off the Pentax KP, a rather compact magnesium alloy body DSLR with a 5-stop, 5 axis stabilisation system and ISO 819,200. The body is not particularly beautiful, but inside it waits a noise reduction co-processor that, by first appearances, rivals DxO’s PRIME software, but acts instantaneously. (If you’ve used DxO’s engine, you’ll know what I’m talking about.)

Technical expose:High ISO images are noisier on average than low ISO ones. The noise cannot be neatly compressed, increases file size and slows down the process of writing files to storage (SD card in most cases). This can affect frame rates. In order to keep the frame rate up, Pentax used to apply noise reduction in RAW from ISO 3200 (several models including at least the K-5, K-5 II, K-5 IIs, K-30 and K-50). This was not configurable and led to mushy images that did not respond well to further noise reduction using other methods. So the way to work with these cameras was to underexpose ISO 1600 by up to three stops, depending on your need – not the best idea if you want to maximise colour tonality, but it got the job done.

Where the magic happens:
the accelerator unit.

But from samples I’ve seen, the new co-processor, dubbed in the latest press release a “state-of-the-art accelerator unit”, renders such concerns obsolete. In the samples, ISO 6400 looks rather clean, and I’m curious to take a closer look at ISO 12,800. Several in the Pentax community have commented that they might delay their entry into full frame based on this camera’s performance, so the pressure is on for Pentax to bring the accelerator unit and high ISO performance to an updated K-1 full frame camera.

Launch price for the Pentax KP is going to be 1100 Euros/Dollars; the Pentax K-70 with similar performance up to ISO 102,400 (also has accelerator unit) is about 400 Euros/Dollars cheaper.

Conclusion: The Pentax KP’s combination of five stops of stabilisation with state-of-the-art in-camera noise reduction will save you money on bodies, lenses, and software, as Pentax leapfrogs the competition. Bring on the night!

    Instead of investing in sorely needed AF improvements, Ricoh only came up with some fluffy marketing stunts like ISO 819200 or changeable grips etc. but Nothing that enhances workability or image quality. No need to ‘upgrade’ my old K3 to this frumpy looking gadget!

      Hey Takuan,

      I actually really like the new edge detection mode. That’s a real help for manually focusing at night. So for me, it’s a much improved camera. But if you have a K-3, I can understand wanting to wait for the “K-3 III” later in the year.
