No need. You can use the K70 interval shooting mode and enable focus at each shot, you can do so in menu C2/12/13, user manual page 72.

Yes, it's kinda obvious to do so, if the camera isn't connected there is no access to the settings.

Internal memory, like the mechanical shutter, may be replaceable for a few years.



Back when the 645Z , it seemed I couldn't afford to buy a medium format kit. Looking back, I bought a K1 and K1II new (that's 4000+), I bought 9 DFA lenses new (that's over 10000+), tripods, filters... I with that money I could have easily bought a 645z and lenses. Sometimes we spill the money wide on cameras and lenses that aren't essential, don't get as much use, when you could just focus the money on core equipment. When I see how frequent apsc camera upgrades are, I can find a lot of customers who say they can't afford medium format who actually spent more on apsc.

That's right. In Europe, a couple years ago I was looking at the largest volume of poster type photo prints (also the cheapest prices per square cm), and I found it was 50cm x 70 cm or 50cm x 75cm , for panoramas 50cm x 150cm (stitched images). That's the most popular large size for people who print, and such sizes pretty much matches the 24Mpixels/36Mpixels quality. We shouldn't confuse causes and effects however. The mass is satisfied with 24Mpixels also because that's what it is being sold. Let's say tomorrow, most marketing folks decide the brainwash everyone that 24Mpixels is bad, and 100Mpixels is the new must have for photography, people expectations will shift to 100Mpixels. I mean, 20 years ago, some people like you right now, were saying we settled on 7 megapixels and your 6Mpixels camera was more than enough. Except for needs anchored in vital needs, such as for commodities, the need for non-essential goods is floating and in constant change as a result of innovation and mass marketing interaction with markets.

What I don't like about camera reviews is when reviewers don't know the camera inside out. For instance, this reviewer says that with Pentax K1 you can't see how the jpeg picture will look like, whereas you see what you get on mirrorless. But what the reviewer doesn't know is that the K1 offers infinite variations of jpeg rendering after you take the picture even when you shoot in jpeg mode, because the camera keeps the last exposure in memory as a raw file for as long as the camera remains switched on. With the K1, once you take a picture in jpeg or raw mode, you can immediately make unlimited jpeg duplicates of that picture just by pressing the left side button on the 4 ways controller , chose a jpeg adjustement to your liking and press ok, you don't even need to press the image review button. Few people know that. That's even better than mirrorless because if you shoot jpeg with mirrorless you can't have multiple variations afterwards, with Pentax K1 you can.

Yes I know what you mean. You looked at the color wheel diagram on camera display, and you notice the color wheel diagrams of Portrait and Katen are similar. But be aware that the color wheel diagrams shown to camera user are top finishing layers, there are intermediate color processing layers between raw data and top layer that Pentax doesn't show you. I'm been there..., I tried before you, years ago.

Yes.


You've just confirmed what I meant. The difference between 24Mpixels and 36Mpixels is the difference between 4000 pixels and 4912 pixels on the short side, not a big difference. In order to double the print size, you need four times the megapixels, e.g from 25Mpixels to 100Mpixels = print from A3 to A1.

You bought two cameras, which you say give you about the same (not much difference in practice). You could have bought only one, even if that one camera was twice as expensive.

I bought a K1 and K1 II (no difference, practically), and 9 lenses, I use 3 lenses mostly, because the first lenses I bought I bought them because the choice was limited. I could have spend half the money, or for the same money I could have bought a 645z or GFX with 3 lenses, or a flagship FF with high performance AF and I wouldn't be lacking anything. Camera companies are releasing products in "zig zag" fashion, sequentially and without telling in advance what products they are going to release and when they are going to release them, and they advertise the most when the system is new and incomplete. If you buy a camera when the system is new, you don't have visibility of what's coming next, so you buy what's available, then they release something better, so you want the newer better camera or lens, and so on... it's a game. If you want to buy only what you need and nothing else, you have to wait (5 years or more) until the lens system is fairly complete and they've ironed out the bugs and issues on cameras, then you have the full view on the system to make a good choice, but then the camera tech is obsolete, so it's a never ending game that drains cash from bank accounts. For apsc cameras is differences between camera models were even smaller: you were sold a 10Mpixels camera, then 12Mpixels, then 14Megapixels, then 16Mpixels, than 24Mpixels, while they could have waited a couple of years and go from 10Mp to 24Mp in one camera iteration.

Won't work in camera because you only have global adjustments in camera. KATEN shifts HSV (Hue, Value, Saturation) for certain hues more than others, especially for the blues and greens.
You may be able to create a custom profile in DCU using color controler , starting from an original KATEN picture of a color chart, and adjusting HSV for each tile of the color chart to match the colors of your reference KATEN image. You work step by step.

First you must have the same exposure, either via camera or via exposure correction in your PP software.
Second, you must have the white balance applied so that grey tiles don't have any color bias.
Third you work on matching the tone curve by using grey tiles from dark to pure white, so that you have the same common contrast applied to all colors, black, white and shades.
Fourth, you work on your HSV or HSL for each color tile of the color chart.

A lot of customers buy cameras based of prices that look affordable relative to their average income, typical camera price from $1000 to $3000, so they own quantities of cameras and lenses having similar photographic qualities, but that are mostly redundant , same aspect ratio, similar sensor sizes, similar megapixel count. Same economics as for telecom subscriptions: if you ask people what is more expensive, a monthly subscription of $30, one time payment of $300/year or one time payment of $600 for 3 years, most people will feel $300/year and $600/3 years are more expensive than $30/month. So the largest segment for digital camera is for cameras or lenses that are priced around $989, when seeing that price, people instantly compare to their monthly income, and they think "$989, hummm, yeah I can buy that". It's much harder to sell an Hasselblad 100Mpixels camera at $8000, although that camera will outlast 10 years of consumer camera upgrades, while the total cost will be the same or less.

That's normal because you made sure active lighting is dominant source of light, and mat black camera would bounce that light as little as possible, minimizing observer effect. Everything being relative.

I don't think we'll see a K1 Mk III (with K33 features) any time soon if the idea if to offer a K3 mk III (fast but without flip screen) as a companion to the K1 body (slow landscape, with flip screen). IMO, they'll wait to "force" customers to get both K1 and K3 III bodies, so that to also sell apsc lenses and thus get more money out of customers, a bit like Canon with the 5D / 7D series, and Nikon with D8xx and D500 series. I would like Ricoh to know that I know the trick, and I won't buy a K3 III, I may jump ship instead (the Ricoh marketing trick turns out to lose customers). The big issues I see with releasing a K1 Mk III with 62Mpixels, 101 AF points, and quicker burst rate, better buffers, better memory card tech, is that once you get that camera you'll be fully satisfied , very happy Pentaxians, and you won't feel the need buy another cameras for a very long time, that could be a business problem for Ricoh as well. Whenever Ricoh release a K1 III with 62Mp sensor and K33 specs, they'll see a HUGE demand for it , unable to produce enough to honor all customer orders, but after the initial period of intense sales, large profits and extreme success of the new K1 III, they'll have to deal with customer need being completely satisfied, which will be a huge problem for Pentax long term, as Pentaxians won't need to buy a new camera for 10 years or more.

Some months ago, Ricoh issued a press release about their camera business, they would replace mass production of cameras by workshop style production of cameras and they would re-organize sales around online direct sales. The press release didn't clearly say if Ricoh would stop making Pentax cameras/lenses or not. New lenses were planned in a road-map, but no further news / progress were provided since the press release from Ricoh. Some people decided to sell their Pentax kit, no sure if it was due to the press release or unrelated. Other people are hoping to see new Pentax products in the coming years. While other people are satisfied with their current Pentax kit and took no action. What we can see right now is that Ricoh are still selling Pentax cameras and lenses, even with some renewal such as the new pentax.eu site (which look nice BTW), no much change so far in Europe. As for the Pentax R&D, if it is maintained or not , I have no idea, we will see a year or two down the road.

Yes, but if you buy 3 Tamron lenses that cost half the price of the Pentax re-branded ones, the D850+lenses doesn't cost more than the equivalent Pentax kit (if you buy 4 Tamron lenses, the D850 kit becomes cheaper than Pentax).

Falls colors appear mid November in Kyoto, Japan, still a couple month left to introduce the autumn color profile that I will never use anyway. So far as I understood from JPT, Ricoh Imaging is under some significant reorganization, pulling GR and PENTAX apart, charge of leadership etc. (classic corporate things) and this won't come without shattering projects, firmware projects, lens projects, camera projects, everything. Every time companies reorganize they lose time, and time lost in reorganizing is time not spent on product development.

As I can see with one of the photo labs I use, they have multiple options for prints on acrylic glass (plexiglass), depending if you want the print to be in front of the glass or at the back of the glass, and if you want the print to be the used with back lighting, ambient light, or both. There is a light diffusing layer, so in all cases you only need to add light at the back. Best is too look at available options from your lab.

I once shot my x-rite color passport, white balance side, to set a manual white balance for the camera, while wearing a red jacket. I had some doubts, so I took off my jacket and shot the white balance card again. And I could confirm on computer that the light bouncing off my jacket was enough to skew the while balance metering. Something to be aware of.

Jet black camera would change the light falling on the subject if Jet black camera shape doesn't emit the same light as in absence of camera and photographer, a phenomenon also known as the observer effect (https://en.wikipedia.org/wiki/Observer_effect_(physics)).
If you want to photograph a subject as the subject is when you are not there, you need to paint the camera and yourself with the same color as the surroundings (which could be funny).

Exactly, you are right. I understand what you are doing, zooming or cropping. For maximum flexibility you could get a Sony A7RIV (61Mpixels should allow you to crop or not crop) and Sony 200-600 zoom, but then there will be times where 600mm isn't enough, and times where 1200mm isn't enough. So when your longest telephoto lens is too short (or when your subject is too far or too small), you just don't take the picture and you don't have to worry because there will be new better photographic opportunities, no worry, no frustration, no stress. And by doing just that, not taking pictures that you know aren't going to be nice, you improve the overall quality of your photos. Same with landscape photography, sometimes the landscape is nice but the weather doesn't play well, in that case I don't take the picture, I leave the camera in the bag and scout the location , take notes, so that I will come back later when the light in fantastic.

Ah, if you do that, it means you haven't reached your best level of mastery in photography. Mastery in photography means the subject conditions don't control how you react, and instead you create the conditions for successful images. When I understood that, I took a lot less photos, but quality of the photos I took increased dramatically. Mastering the conditions and deciding not to shoot if the conditions aren't met, is , IMO, what makes the difference between a pro who is able to deliver consistent high quality images, and the hobby photographer who kinda get a high quality shoot once in a while by being lucky.

When using a zoom you aren't supposed to crop, or if you need to do so means your zoom has the wrong focal length range for what you are photographing, because with zooms you are supposed to zoom-in or zoom-out to fit the subject within the camera frame. I know a lot of hobby photographers use zooms for birding in europe, and the zoom is always fully extended, which means, not only the zoom functionality is never used, but on top of that the zoom optical design is a "good enough" compromise that delivers reasonable sharpness profile when using the full frame across the focal length range. So if you know you are going to shoot small birds in Europe, it's better to use the longest prime lens you can afford. And if you're going to shoot elephants from a Jeep in South Africa national park, a zoom is better because you often have to zoom out to fit the elephant in the frame.
