[0.02 lb] I have had this camera for about 4 months now and I am very very happy with it. I have been using a mirrorless full frame camera for the last 5 years, but the prospect of a monochrome-focused camera was too good to pass up. I specialize in monochromatic images and have a lot of success selling them in a gallery in Juneau, Alaska. This has brought an excitement to my artwork that I haven't felt in some time. It really brings a film-grain richness to the images, the noise is handled beautifully, and the dynamic range is excellent. I ended up selling all of my Sony FF gear and am all-in with this beauty. I also print a lot of cyanotypes from the files and this camera has improved my digital files I use for the digital negatives I use in the process. Thank you, Pentax, for thinking outside the box.

[0.02 lb] To preface this story, this is my first DSLR and my first Pentax.
Before this I had owned two mirrorless cameras. 
First I started with a Lumix S1 but was looking to upgrade and convinced myself to sell everything to buy into the Fuji GFX system.
To my (and many others) surprise I was dissatisfied with not only the build quality of the 50sii but the images I was creating with it.
Something just didn't look right. I couldn't place my finger on it but things looked... sterile? 
I thought a digital medium format sensor was the answer to replicating my medium format film cameras but alas, this was not the case.
I wanted to capture a black and white film look with a digital camera but couldn't afford a Leica monochrome.
It was a risky move on my part but I sold my GFX after doing a lot of research into the K3iii monochrome.
The first day I took it out I knew I had made the right choice.
Images from this camera are pure magic and have tricked many people around me thinking it was film.
Match this sensor with a M42 adapter and throw some Super-Takumar, it looks identical to B&W film.
Love shooting this thing at night at ridiculously high ISO levels.
The build quality is like a tank. View finder is bright and easy to focus. Speaking of focusing, the auto focus is faster than some of the mirrorless cameras Ive used.
I don't ever want to go back to mirrorless after using this gem, there's nothing like framing your image through the lens.
My only complaint is it takes a second to get used to exposing correctly. You need to be very mindful of blown out highlights.
Images match that of any full frame camera I've ever used.
I love this thing so much I can only hope Pentax will release a full frame monochrome camera in the future to compete with Leica.
Anyway, if you love B&W photography then this is the camera for you.

[0.02 lb] The Pentax Monochrome, following Leica's lead into digital black and white photography, opens the doors for affordable, high quality rebirth of B&W images for hobbyists and professional photographers alike.
As a young hobbyist I will never forget watching my first image emerge in the development pan in the dimly red light room. A second AHA moment was my first view of B&W negatives taken with my first Leica rangefinder camera and lens. I now have a third, and possibly most important event, that occurred when I reviewed my first images using the Pentax monochrome camera -- finely nuanced B&W pictures that virtually jumped off from the view screen. My first thought was that I had been shortsighted and tight-fisted by my initial response to the high price of the Leica Monochrome cameras. My second thought was that there now exists a clear, challenging future for hobbyists and professional photographers. The question most photographers now have to answer for themselves is how best to capture their images. There is a bright future awaiting B&W photography. The Pentax monochrome is an incredible photographic instrument at an unbelievably low price. Leica opened the door to 35mm photography and now has opened the door to digital B&W photography. The Pentax DSLR is the first to follow Leica and has done so with its SOA improvements to DSLR cameras. It will not take long for all the usual copycats to compete in this new and exciting dimension of photography.

[0.02 lb] I shoot low-light events in Las Vegas: Concerts. Indie wrestling. Pagan rituals. The other cameras in my stable were proving insufficient; I needed more stops. I bought this with the hopes of getting more stops.


I can now shoot deliverables at ISO204800 (attached).


The K3iiiM is my favorite object. Thank you, Ricoh.

[0.02 lb] Coming from a Pentax K1000 owner since 1978, I have to say that this K3iii is the most impressive Pentax camera that I have owned as of yet. I'm very happy with the purchase.
Thank you B&H.

[0.02 lb] I am amazed how technically advanced this camera is. I am not a professional but am happy that I purchased this camera. It is also compatible with my other Pentax lenses from prior Pentax cameras.
I will be learning a lot with this amazing camera.

[0.02 lb] The Eyecup replaced one which I lost. It fit on my K-3 just fine. Thanks to B&H for their speedy delivery.

[0.02 lb] This camera appealed to me because it promised a quirky experience--an optical viewfinder and no ability to capture color. Based on my usage of the camera to date, Pentax delivered on that original promise. The viewfinder is bright, and the sensor produces tonally rich images. This is my first and only digital camera from Pentax, yet I didn't have trouble learning the camera's core functions. It feels well-made, which adds to the joy of using this camera. I think it is a great tool for exploring black-and-white photography.

[0.02 lb] I haven't picked up a color sensor camera since getting this camera. Behaves very much like film where you use color filters to correct color tones into B&W.

[0.02 lb] I upgraded from the K-3 to the K-3 Mrk iii and totally glad I did! My K-3 is now my back up camera while on location.


One of my favorite new features is the toggle switch on the back to toggle through and move the focus points. This has been very welcoming while shooting landscapes and also portraiture and can be used which wearing thick gloves.


Pentax's weather resistant body and lenses are top notch and allow me to be out there doing what I love no matter what mother nature dishes out.


I have tested out the ISO range only up to 51200 and it did well. Expected grain which is easily reduced in post processing. Iso range is from 100 to 1600000.


Great camera and Great Quality. Well worth the investment!
