Due to Fowa, the parents who convey Pentax cameras to Italy, I obtained an opportunity to check out the Pentax K3 MkIII monochrome (purchase right here) for just a few weeks. If I have been to sum up how I really feel about this digital camera, it could be this: I’m in love.
I’m a fan of black and white pictures, each in movie and digital. That is the primary time I’ve used a digital digital camera the place I felt just like the digital camera is simply serving to me create my artwork as an alternative of being a sophisticated gadget that I needed to wrestle with.
The Pentax K3 monochrome
Let’s discuss concerning the Pentax K3 monochrome itself. The Pentax K3 MkIII, the common shade model, has been round for a bit. It’s a wonderfully made 26 Megapixels Aps-C reflex digital camera that has acquired constructive suggestions from many photographers. The physique is sturdy, weatherproof, tremendous user-friendly, and has an incredible viewfinder.
Regardless that mirrorless cameras are all the craze as of late, Pentax has caught with reflex cameras. Should you’re somebody who actually appreciates optical viewfinders, you’ll actually admire the high-quality viewfinders on Pentax cameras. I examined the K1 MkII, a full-frame digital camera, and the K3 mkIII, and I can inform you that although the K3 has a smaller sensor, it has a superb viewfinder that doesn’t appear restricted by its dimension.
Pentax has an awesome status for top-notch development, and I have to say that I’ve at all times discovered Pentax cameras to be very snug to make use of, with a deal with good ergonomics. They appear to suit my hand completely, and the buttons at all times appear to be simply the place I want them.
The monochrome model of this digital camera has the identical precise physique and construct high quality as the unique, however with a slick all-grey look. The parents at Pentax actually put within the effort to make the Monochrome physique look distinctive.
In each variations of this digital camera, you’ll discover which you could simply attain the principle features utilizing the customizable buttons and the very well-organized menu system.
The Pentax K3 monochrome Black and White sensor
Now, let’s discuss concerning the sensor within the monochrome model. It’s the identical 26 Megapixels sensor as the colour model however with out the colour Bayer filter in entrance of it. This leads to a number of benefits for black and white pictures. The noise within the photographs is lowered, and also you get extra natural-looking photographs with none unusual patterns or artifacts.
In a nutshell, with out the Bayer filter, the digital camera can create a clearer, higher-quality picture. If you wish to study extra, here’s a geeky rationalization. Be happy to skip, if figuring out that monochrome sensors typically produce higher pictures is sufficient data for you.
Monochrome sensors vs. Colour Sensors
As a way to seize shade data, digital cameras use a course of known as demosaicing. This course of is important as a result of most digital cameras use a picture sensor that’s inherently monochrome. Because of this each pixel within the sensor can solely seize the quantity of sunshine hitting it, however not its shade.
To get round this limitation, digital camera producers cowl the picture sensor with an array of tiny shade filters in a sample often called the Bayer sample, which is called after its inventor, Bryce Bayer of Eastman Kodak. This sample consists of a 2×2 grid with two inexperienced filters, one crimson filter, and one blue filter. This association is because of the human eye’s sensitivity to inexperienced gentle and gives extra decision for this shade.
In a typical Bayer sample, 50% of the filters are inexperienced, 25% are crimson, and 25% are blue. So when gentle hits the sensor, every pixel can solely seize one of many three major colours. The lacking shade data for every pixel is then interpolated from the encompassing pixels throughout a course of known as demosaicing. For instance, a pixel with a crimson filter will use the close by inexperienced and blue pixels to calculate its inexperienced and blue values.
Nonetheless, this course of isn’t excellent and may end up in artifacts, similar to moiré patterns or false colours in high-frequency particulars. The Bayer filter additionally blocks a good portion of the incoming gentle, which reduces the signal-to-noise ratio, a key think about picture high quality. That is particularly vital in low gentle situations the place the digital camera has to amplify the sign, which additionally amplifies the noise
Pentax K3 monochrome picture high quality
By way of picture high quality, this digital camera is an actual powerhouse. I used to be blown away by the outcomes whether or not I used to be capturing within the studio or out on the planet.
The digital camera performs very well as much as 6,400 ISO, and the pictures have a nice grain, just like a low ISO movie, as much as 51,200 ISO. And even on the most sensitivity of 1.6 million ISO, the pictures are nonetheless fairly usable.

I in contrast the K3 MkIII shade with the Monochrome model, and the distinction is basically noticeable. The pictures from the Monochrome digital camera are extra naturally sharp and pleasing to the attention.
Actual-world use
After I’m testing a digital camera, I prefer to see the way it handles each common and difficult conditions. It helps me perceive what it could do on a day-to-day foundation and the way far it may be pushed. I used to be clicking pictures on the Vicoforte Mondovi Sanctuary in Italy, and I believed I discovered the digital camera’s restrict. There was this window with daylight blazing by means of, making a robust distinction with the darkish church inside. However guess what? The digital camera took it in stride and nailed the distinction!
Check out the JPEG model of the picture. Discover how the darkish areas are nearly invisible? Now, examine that with the processed RAW file. I managed to convey again the shadows and particulars with out introducing a bunch of noise. Fairly spectacular, proper? I had the digital camera set at 400 ISO and used a setting on the meter to protect the highlights, a nifty characteristic on the K3 MkIII, accessible in each shade and monochrome.
This picture additionally reveals why you may need to decide RAW over JPEG as your go-to file format.

The Pentax K3 MkIII, in each its shade and monochrome variations, has this actually useful publicity meter setting. It helps hold the brilliant areas of your picture (the highlights) from getting too shiny. That is particularly helpful for the monochrome model as a result of it’s tougher to repair overexposed highlights with out the three shade channels. So, whether or not it’s you or your digital camera’s meter, be certain that the pixels don’t wander too far to the precise on the histogram.
Each topic I shot, be it night time scenes or fields beneath a cloudy sky, was fantastically captured by the digital camera when set to automated publicity mode. The K3 Monochrome is tremendous user-friendly due to its wonderful publicity meter.
Pentax K3 monochrome dynamic vary
One other factor that wowed me about this digital camera was its dynamic vary, or what we used to name ‘publicity latitude’ again within the movie days.
I needed to see how a lot dynamic vary the digital camera may deal with, particularly after noticing how properly it dealt with the darkish areas. I photographed a shade goal on my bookshelf, and the outcomes blew me away.
The digital camera may simply recuperate particulars from a picture underexposed by 5 stops. A little bit of noise crept in at -7 stops, and at -10 stops the noise was extra noticeable however nonetheless manageable in a pinch. Principally, you may have elements of your picture underexposed by as a lot as ten stops and nonetheless recuperate some particulars, attaining a Zone I within the remaining print. Nonetheless, you’d need to keep away from overexposing with this digital camera. The higher restrict is round 3 stops, possibly a bit much less.
In comparison with the colour model, the distinction is stark. The colour model has a couple of cease’s price of benefit in overexposure, however the Monochrome shines in the case of underexposure, leaving the colour model trailing by at the least three stops.
This isn’t shocking for the reason that absence of Bayer filters leads to a greater signal-to-noise ratio, which is a giant motive for making a devoted black-and-white digital camera.

Mid-tones on the Pentax K3 monochrome
One factor that stands out with the Pentax K3 Monochrome is its dealing with of mid-tones, or the shades of grey between gentle and darkish. It blends these tones easily, and but every tone is distinct. Even if you happen to loosen up very darkish areas throughout enhancing, the standard of the mid-tones stays top-notch.

Submit-processing
Modifying pictures taken with this digital camera is a breeze, due to its excessive dynamic vary. Principally, you simply have to tweak the brightness and darkness ranges and typically convey out the shadows.
Whereas it’s true you may’t use shade filters in enhancing, you may simply get round this through the use of filters once you’re capturing, identical to you’d with movie.
It’s widespread as of late to see pictures which might be closely edited, so having some limitations can really be an excellent factor. This digital camera encourages photographers to be extra considerate and inventive earlier than taking the shot, reasonably than fixing every thing afterward on a pc display screen.
Pentax K3 monochrome conclusion
Pentax actually nailed it with this digital camera. Should you’re a fan of black-and-white pictures, this digital camera is a strong funding. The pictures it takes are noticeably higher than what you’d get from a shade digital camera.
In a world the place it looks like each new digital camera is only a slight variation on the final one, it’s refreshing to see an organization strive one thing totally different and pull it off so properly. Should you’re on the lookout for a pure black-and-white digital digital camera, your different possibility is a Leica, however these aren’t SLRs and so they price about as a lot as a kidney. So, hats off to Pentax for doing an incredible job!
