My K-1 II is barely a few months old, and my DC Adapter was purchased new just a few weeks ago. Today when I tried to do some scanning the camera would not take power from the adapter. It does power on with batteries. I tried a different power cable and outlet. I tried a reset of the camera functions too...no dice. Seems like an odd thing to quit on me so early.

Of course the frustrating question is...camera or adapter? Is there anything I should try before requesting a replacement from B&H for the adapter?

Hoping for a Pixel Shift Upgrade...

So far there were two approaches to Pixel Shift from my understanding. One was the Pentax mode which we call know and love. It essentially uses pixel shift to get around the need for bayer demosaicing. You get the full possible image quality of the sensor. The other was the Olympus super res mode, which increased the pixel count. Given that 36mp is still a lot, I prefer the Pentax method.

I'm not sure if Pentax users noticed but two new Pixel Shift capable cameras have been released. The Sony A7R IV, and the Panasonic S1R. These models combine the Pentax and Olympus method to get around bayer demosiacing and increase resolution. I believe the Sony makes 8 captures, and promises 240mp.

Now I don't get too excited about MP increases for practical photography. However I primarily use pixel shift for scanning film, a task to which it is perfectly suited. When you go to formats like 1:1 you pay a significant resolution price with single capture scans. You get around this by taking multiple scans of the film in sections and stitching them together. 6 captures of a 6x6 negative yields close to 4000ppi. The super resolution mode that the Sony and Panasonic may reduce any need for stitching, which is time consuming and can be challenging at times.

I guess I am just hoping that Pentax can upgrade the Pixel Shift mode in a firmware update to offer more captures in pixel shift mode to increase resolution.

MZ-S AF Issue
Posted By Sperdynamite

Hi! Just received my MZ-S from KEH yesterday and I have been using it with my 43mm 1.9. Seems like a match made in heaven so far.

The only issue I've been noticing is that the AF seems resistant to picking infinity when focusing at distant subjects. More often than not I notice my infinity target looks a bit soft, and the lens has settled on the 8m marker. The AF system doesn't seem to have issues at other working distances. Up close, at least from the image in the VF, the focus appears sharp. Is this typical behavior or am I misusing the AF system in some way? I have the camera set most of the time to center point AF.

Thanks!

The K-1 is a marvelous studio camera considering Pixel Shift. I wish tethering wasn't such an afterthought for them.

First engagement session with the K-1 II and the 43mm done! I was using a Hold Fast camera harness so I had the D810 with a 50/1.4G and the K-1 with the 43mm available to me on either shoulder.

I really love the images with the 43mm. The contrast and character of the old Limited lens really stands out. The 50/1.4 was obviously able to produce blur the background more and was a little better for tighter shots, but when I was working a middle distances with the 43 it really shined. I think I prefer the 43 to my usual 35 because it doesn't really distort the subjects in the same way, and I can be ever so slightly further from the subjects.

The Pentax definitely has preferable out of the camera color and contrast. It seemed so render a bit more low-key than the Nikon so it's somewhat of a difference between 'light and airy' and 'moody'. However I was shooting at dusk so my perspective is that the K-1 more accurately represented the feeling of the light at that time. YMMV with this because no-image-goes-unprocessed. Ultimately I will tweak these images so they have a consistent look, and I have often argued that out of the camera color is essentially a non-issue in the age of presets and profiles. Raw is raw. But the DNGs the Pentax created are very lovely raws.

The AF did not keep up with the Nikon. This is a surprise to absolutely no one! I would describe it as slightly better than I expected however. It was able to modestly track my subjects during walking shots, though this resulted in more out of focus images than my Nikon would when using AF-C 'Group' mode. On the Pentax I would use AF-C and the mode where about 9 boxes are highlighted, and move that target around as needed. The actual AF reach didn't bother me so much. The points were within compositional norms. I wish it was slightly better when my subjects were not moving however. It did not miss much, but it did from time to time and that was frustrating. My Nikon would never miss in those situations.

The 43mm is not a soft lens, but the AF misses will make you think it is. It's plenty sharp even at 1.9! Throw a modest amount of sharpening on there and it's razor sharp. Stop down to 2.5 or 2.8 and there is nothing holding you back.

I tried a hand held pixel shift on a landscape before my clients arrived. It works! I don't know why the reviews Poo-Poo this mode, as I see a significant increase in resolution, especially on distant objects in a landscape. However as I experienced with the HDR mode, the in camera processing slow down is egregious. So I won't try HDR again during a portrait session haha!

If you watch this segment you'll see a photographer featured who appears to be shooting with a 645Z. I have seen more than a few people shooting with Z's over the years. I think it was something of an understated hit. I hope they keep it up with future models and lenses.

Thanks all!

Yeah as much as I loved the K-5, I shoot A LOT of film. (Actually I own a film lab here in Maine called Northeast Photogrpahic). Crop cameras were just not going to work for me. When it seemed like Pentax was not going to embrace full frame I switched to Nikon, which was my first brand anyways. Nikon obviously makes some of the best cameras and lenses out there, but with a few exceptions they can be a little bit boring. I have an F6 which I LOVE, but nothing about the system is 'charming' so to speak. The Limited line up has 'use me appeal'. I hope Pentax can still embrace that design ethos, but even if they don't they already make everything I need.

Re Pixel Shift scanning, yes full pixel color readout is important when it comes to large large prints. It seems counter intuitive, but CMOS sensors do have some noise present even at low ISOs which really reveals itself when doing this kind of work. Every scan needs some post production work, and some sharpening, all of which can increase noise. A pixel shifted scan greatly improves my ability to fine tune a scan. CCD line scanners, Imacons...'normal' scanners all use full pixel readout to achieve their effective resolutions. In theory, the K-1 should be achieving full sensor resolution. This means you're meeting or exceeding a Coolscan 5000, or even Imacon. But to know for sure I have to do more tests.

I just received my K-1 II today! It feels good to be back to Pentax after an extended affair with Nikon. I have fond memories of the K5 and my set of Limited lenses. The K-1 II does not disappoint so far...

I purchased it with a 43mm and 100/2.8 WR Macro. I intend to use the 43 for normal shooting and the 100 for my DSLR scanning rig. True to their reputation these lenses appear tack sharp, and IBIS is remarkable.

The AF seems better than my memory serves from testing the K-1 (Mrk 1). It just seems more confident, and it doesn't have much trouble in semi dim light. The area though is of course very narrow for this day and age, but the responsiveness feels no different from my D810. I'll be shooting an engagement session Saturday so we'll see how it does on the job.

I did some brief testing with pixel shift once I finally got it to tether to my iMac. The difference (at least on the Provia 100F 35mm frames) is certainly subtle, but no surprise the PS files are better. You really see the difference when you apply sharpening. The single capture files get noisier while the PS file remains clean, and shows more fine detail. Still at a glance, it's hard to see. However when it comes to fine art scanning and repro, small differences go a long way.

So far I'm delighted! Now I'm just trying to track down a film option. I've got my eye on a few LX or MZ-S bodies...

Re: why am I looking to get back into Pentax.

I used to have a K-5 and I really liked it. At that time Pentax was doing the Fuji thing saying they would never make a FF body. Thus I went back to Nikon. Nikon treated me well for a while, it's really the ideal wedding system, and I'm not fully leaving the system since I own an F6 which I will never sell.

I do a TON of DSLR scanning. A lot a lot. I've long been wanting a K-1 to get around bayer type sensors for scanning.

I also just loved Pentax limited lenses. I've really wanted to get a Pentax film body and the trio of limited lenses for a while to do my fine art reportage work. The K-1 I'll use for scanning and the weddings I still shoot, along with a D810 and a medium format digital rig I have. Once I get the K-1 I'll sell the Nikon macros I have. I'll likely hold on to my Nikon AFD lenses, and invest in the Pentax 100/2.8 Macro for scanning. Then I'll get the 31 and 77mm lenses. Eventually I'll get the 43, but to start the 55 sounds more useful to me as a wedding/portrait all-rounder.

I no longer have my old 58mm Nikon. It does not focus well on an F6, and the expense of the lens keeps me from having it around just for the dozen or so weddings I shoot a year.

I own a lab called Northeast Photographic. I scan film with two Fuji SP3000s, along with a camera copy rig for E6 film, large format, and certain fine art applications. A stitched, pixel shifted scan is likely to rival Imacon level scanners for quality.

Two things can be true...the 50mm DFA is good and the 55mm is also good. Maybe they're both good for different reasons? I'm literally just asking if anyone happens to have any portraits shot with the 55 that they'd like to share.

Reason why in the context of a wedding a 55 or 58 might be preferred. When you focus close with a 50mm you begin to have a little bit of face widening, where as a 55/58 acts a tiny bit more like a portrait lens and is just a bit more pleasing. Also the 58/1.4 has the same effective DoF as a Noctilux at 1.0, just thanks to the slight extra reach. AGAIN, the DFA is a fine lens, but some people may choose to use other lenses for their own reasons. Same reasons why someone may have wanted to own the 43 over a 50mm. Little differences go a long way, and one person's preferences don't invalidate yours.

I'm not sure how this forum is about linking to other forums, but here is a great place to start if you want to see what folks are doing with the 58/1.4. Just trying to find out if the 55 has the same magic.

The review samples are great, but I'd like to see some actual people portraits at close and middle distances at 1.4 and 2.0. Just asking in case someone has them. Also not at all knocking the 50/1.4 that just came it, but it just won't be the same rendering for people and detail work.

I have used the Nikon 58mm lens extensively at my weddings. It has an absolutely gorgeous rendering that makes it look almost medium format at times. You can see examples of this on the thread dedicated to it at FM. However I'll be getting into Pentax soon and I'm wondering if the 55mm is a good replacement for the 58? Similar focal lengths, same aperture. The 58mm is not famous for sharpness, just knock down drop dead gorgeous rendering. Would anyone be interested in blowing up this feed with 55mm 1.4 portraits on the K-1?

Controversial Opinion: Sony Was Right And We Were Wrong...

I told you in the title that it's a controversial opinion lol!

As I said, it's not for everyone and I'm sure a DSLR maker wouldn't only offer an SLT option if they went this route. When I look at high res cameras like the D850 though, and know that the OVF can only show you the DoF at 2.8, I think an EVF could solve this problem. Brands like Pentax and Nikon have big manual focus lines that are nearly impossible to use at wide open without a little luck or a focus assist. Cinematographers have used video taps for years for the same reason. Plus eye-af is a real and meaningful technology, not IIRC available to OVFs.

I would love to nail focus with a 50mm 1.2 manual lens on a 45mp sensor, using a picture in picture view, but that's just me!

I'll try to keep this little Op Ed brief, but I've been thinking about this for a while.

Ricoh managers recently made a statement that was mocked a bit, I think unfairly. Mirrorless users will return to the DSLR after a few years. I for one did just that. I have owned many mirrorless cameras, such as the Fuji XPro1, X100S, Sony A7, and A7III. The A7III of course was closest to a fully formed camera that competes with my DSLR in a functional way. But eventually I got tired of it and am using DSLRs again. Why? Well what is the point of a mirrorless camera? My understanding was that they would be much smaller, and have nifty EVFs that allowed you to preview exposure and focus in real time. I actually still dig the EVF, more on that later. Size though? Well thankfully Sony does make a few 1.8 lenses that are well mated to the system, but what about their current 1.4 offerings? They're as big as a house! What is the point of a mirrorless camera that is as big as a Nikon D810, only less comfortable to hold? I guess you get worse AF to boot...nice. When I look at the size of your middle range 50mm lens, it's just a crazy comparison. I have a 50mm 1.4 that I think performs just fine, sure the larger modern glass is better but I don't go for all that pixel peeping (shouts to the OG Limited line).

Well way back when Sony made a line of cameras with technology they called SLT. It used a nonmoving transparent meter to bridge the gap between EVF tech, and traditional SLR AF. At the time it was unfairly maligned for taking out about a 1/3rd of a stop, which sounds absolutely laughable in this day of high ISOs. Very few people bought them, even though the later versions had pretty decent EVFs and some truly killer glass (which by the way were smaller than their current A series optics).

It just got me thinking, what if my DSLR had an EVF, and retained it's AF performance. Why would I use anything else? It would make mirrorless cameras look laughably un-ergonomic, which they largely are. Modern EVFs are really good. And previewing the exposure, DoF, and focus near perfectly is a hugely advantageous tool in a fast paced environment. You also minimize mirror slap or shutter shock. I would buy an SLT K-2 knowing what I know now. Sony was right!

*Now I know some people want the traditional VF and I see no reason why a model with one can't be sold alongside an EVF version.

1. I've heard it reported that the noise reduction is hard wired into the raw files. Is this also true at low ISO?

2. In practical use has anyone found that the AF improvements are noticable?

I am looking to get either a K-1 II or I for the handful of weddings I shoot per year (currently with a D810), and also for a DSLR scanning rig. I think the Pentax implementation of pixel shift makes for an ideal scanner, but in these conditions I'd prefer if there was as little in camera noise suppression as possible-understanding that noise with PS and at low ISO is already minimal...

I'm using a "Film Toaster" so the camera rests on a box vertically while macro focusing on a piece of film. It's probably not great to have the focus motor lifting and lowering the camera if the "front standard" of the lens must move in and out. I think there may be a solution around this but I'll still doing some research. So far it's been easy to AF each shot with no camera movement using the Tamron 90/2.8 VC and the Nikon 60/2.8G. The scans have been super high quality, but I'm sure the K-1 could do better with pixel shift!
