Macro Straight Razor

This is a fairly old straight razor I inherited from my grandfather. I believe it was the last one he bought for his barbershop prior to retiring. I never knew him as a working barber, so I suspect it was purchased in the mid 1950s.
I have never cleaned the blade so I suspect the fingerprints visible on it are my grandfathers.

This is a 16 exposure focus stack

Others speculation about Pentax K-1III

What *I* want to see in the K1iii is the end of SAFOX. PDAF is s dead end. Sensor based detection is the future.

And we already has the start of this in the rgb sensor and the way it is used for af assistance in the K3iii.

Time to move forward, discard PDAF and do something like CANON's Dual Pixel AF, based on an improved rgb sensor.

This way we will also get a brighter viewfinder since no light needs to be transmitted to the PDAF system without a need for a K3iii type prism. The whole PDAF mechanism will be gone - size and cost savings. And more.

That's the main thing in my opinion.

Ofcourse a new sensor - no need for a huge jump in resolution, just a current one with a future.

And ofcourse the K3iii new hardware.

And hopefully faster cards.

But mainly, let's move the AF system to the future.

I think you nailed it. Price expectation. Now it depends on customers. With all the DFA lenses I already have, get a new Pentax FF body for $3000-$3500 is still cheaper than switching to another brand, but it depends what the new FF specifications will be. I'm looking for 60Mp resolution for my prints, if Ricoh don't deliver on this, the K1 will be my last Pentax kit before the next non-Pentax upgrade. IMO, not moving forward with the 645z and new medium format lenses, means Ricoh have no choice but to offer a higher resolution FF camera as an upgrade path to the K1, and keep the K1 II for sales as the cheaper alternative.

I think people who buy more than one lens have a tendency to buy significantly more than one lens. People who are satisfied with their kit lens or the kit lens and variable aperture zoom they got with their ILC don't fit this bill and can't imagine spending more money on glass.

I own about 12 lenses. I am probably mostly done buying glass except for the DFA 21 and the 70-300 full frame variable aperture zoom that is (hopefully) coming soon.

I don't mind if they keep the prism same as is on the K1 II. If there is no Pentax K1 II successor with substantially higher resolution sensor, I'll pass on the one, I can keep using my current K1 / II. If Ricoh doesn't provide higher res. in K mount, my next upgrade won't be with Pentax. I currently up-res my file for printing because the native res. of the K1 isn't sufficient, but AI processing time is a pain in the neck, but I can easily imagine I could get a camera from another brand and print straight out of camera, which would same me a lot of time.

I disagree that prism tech is that important. For me, the image output and capture reliability (ability to get sharp detailed and in focus image every time) is more important than a 5% better viewfinder prism.

---------- Post added 27-11-21 at 20:14 ----------


Advancing tech doesn't prevent to release "special" edition models for gear collectors who like to own special objects, special models can generate revenues that don't require much R&D effort. It depends what we're looking for in a camera.
Special models aside, you are right, competitors are pressing forward, there is impressive technology out there from the main three manufacturers Canon, Sony, Nikon (Z9 is impressive). There's plenty of choice of mirrorless camera and lenses now. We'll see.

K-3 AF-C Focus Problems
Posted By carlos.vieira

In my K-3, i'm getting the best results with this settings:

AF-C, SEL-S (center 9-points or more, depending on the situation, but with more points seems to work worst) - tipically center point and recompose/pan
16. 1st frame action in AF-C - Focus Priority
17. Action in AF-C Continuous - FPS Priority
18 - Hold AF Status - Off

For what i've been experiencing, the most penalizing setting from the above, in action shooting, is when setting 18 is NOT off... so, if i set 18 to Low, Medium or High, i get bad results (too much out of focus shots), and worst if i move/pan the camera to follow subject. But, i think setting 18 is just too specific setting. So, i just tend to use setting 18 = off.

But, overall, it seems to not work as expected all the time... is not consistent.

Stuck in monochrome shooting mode

You probably accidentally depressed right side of the 4-way controller with the heel of your thumb. A little more creative thumb work likely resulted in the custom image setting being on the monochrome mode. This is a fairly common problem and was reported soon after the K-3 came onto the market. With time, one's thumb heel becomes better at avoiding the controller and the problem goes away.

To fix, go to the custom image settings (4-way, right) and choose something more appropriate.

There is a strong case for requiring or at least have the option to require a confirmation press of "OK" to change this, but so far hints to Ricoh have not been fruitful.

I'm one of the Nikon converts. Nikon was really starting to annoy me by disabling features on cameras just to position them in their line up. As an example, look at what they did recently with the D7500 by removing a second card slot (compared to the D7200). This is clearly just to ensure that pro's need to buy the D500 even if they don't need the D500.

Pentax seems very much like the company that is dying to give the customer everything they can for the lowest price possible. I want to be part of an ecosystem where people are scrappy and care deeply about what they're making. Nikon seems like they're pretty damn far from that at this point.

I really do love pentax. I do think though that they really need to focus on two things to continue with the momentum of growth and to keep current converts happy. The first is to somehow convince tamron and sigma to continue making lenses for pentax. What tamron and sigma have been doing with their lenses recently is amazing and it does sort of feel like we're missing out. I'd love to be able to get the sigma 85mm art on my K-1. The second thing I think they need to do is improve autofocus speed so that these cameras can be depended on to shoot action/sports. Do something like what Nikon has some with the D500 and add a dedicated processor for autofocus.

I know the pentax community is very tight-knit and many of us are people who come directly from film or are at least "old school." The response to criticisms of pentax seems to basically be "when I was a kid, I had to walk both ways uphill to school in the snow." It's not helpful and it will fly less and less as more converts come to pentax. I would imagine the only way pentax stays alive is for them to find a strong and compelling reason for people to move over to pentax and to stay. The K-1 went a LONG way towards making this reality. I think they need to continue to push. I don't think their full-frame lens line-up that they've promised is enough.

There's no local digital storage technologies in smartphones that are different from digital cameras today.

Smart phones use flash memory, not RAM (in the true sense of the word), for storage. For example iphone 7+ has 3GB of RAM and either 32GB, 128GB or 256GB of flash storage.

Flash memory is the same technology behind all commonly available memory cards, e.g. SD and its variants like SDXC, Compact Flash and its variants like CFast, to name a few.

Fastest of flash memory is much slower than RAM. That's the reason why digital camera buffers are actually RAM.

If you are suggesting to move data to "a sort of memory storage of the smartphones' like" before it is moved to external flash (like SD), for now it doesn't make sense as your "sort of memory storage" is flash and it's like writing to the card twice.

Flash memory is much cheper than RAM per byte. That's one of the reasons why nobody makes a smartphone with 32GB of RAM (not your "RAM", but true RAM).

As of now, I don't know of viable technology that PENTAX can use that is as cheap as flash but as fast as RAM (or even just 10 times as fast as the fastest flash as of today).

If you are claiming that such a technology is already available for consumer electronics, I disagree. There might be many things the camera makers could learn from smartphones, but local storage is not one of them.

OTOH, combination of a deep buffer (i.e. huge RAM) and the latest of fast flash memory technology already works well for digital cameras, e.g. you can continuously shoot RAW+JPG of 20MP sensor at more than 10 fps forever until your card is filled:















You Tube




That doesn't interest me as a buyer, but I'm sure people are paying premium for that kind of performance.


What is childish about a shallow buffer in KP? Maybe you have your own definition of the word "childish", just like "RAM"?

Thank you for sharing your thought, BTW.

How many frames per second can your smart phone shoot, Uluru? What is its lagtime in focusing, taking and displaying each shot? What is its focal length other than wide and distorted? How do you change its aperture from anything other than wide open when its lens has no blades?

I'm very happy for what my Galaxy is, but it is no match for my A7 or especially my K-1.

They own it because nobody else makes a FF mirorless. There is no competition, so obviously they own it. Canon has been working on mirrorless technology for a long time. Video and mirrorless share many of the same needs. A 33MP camera that shoots 30fps is basically an 8K video camera. Canon has the technology to make a competitive mirrorless already.

Just wanted to say I've really enjoyed this conversation.

While some posters have asked, why can't we just celebrate the success of the K1, it was the original poster who opened the door. They celebrated the K1, and then made sideways comments about features/approaches they don't like (video etc.) That opened the door to this conversation, where we could all imagine future models and what we might like to see in them.

Kudos Pentax for making the K1, I will almost certainly buy one. And all the best for the future of Pentax, I hope somewhere in that future there is a solid K-mount MILC with good execution of video and stills :-)

Coming full circle, she might jump ship from film and buy a K-1 after all.

I suppose it led to her choice of Photography as her HS Art elective. There was always a camera in my hand or her mother's, and once you've stepped through a door . . . .

Our Public School District teaches non-core electives as vocations, so Photography was taught as a professional skill, from capture through developing to printing; leading to (mandatory) shooting for Yearbook and Newspaper as a Journalism Class for academic credit; which became Yearbook Photograpy Editor and then Editor-In-Chief, which Yearbook won National Recognition (Mandatory competitive submission); leading to a Media Fellowship for her Undergraduate studies; where she rose to Managing Producer of the college television News Division with English L&L Major and Photography Minor; after which she was recruited by a Network News Division on the Washington Bureau and promoted to Operations Producer for one of the evening nightly news broadcasts in New York. The career chose her.

Actually, her experience has challenged me and renewed my interest in the art. She's home for the weekend visiting her new Nephew and Niece, and we've just spent a couple hours judging my pBase galleries and playing with the K-1.

She's highly complimentary of the camera; less so of the shooter. :D

I agree.
Which means any new Pentax FF camera must be able to handle the three 2015/2016 f2.8 DFA zooms (15-30, 24-70 and 70-200), which, AFAIK, do need a mechanical aperture lever. Those who bought them have invested >$7000 in K1 and K mount recent lenses, including also the DFA 150-450 or 28-105.

And I believe this feature would be very difficult to implement into an adapter to a new fully electronic mount.
Which is why I believe a future first mirrorless FF Pentax should be K-mount.
If it is K-mount, it can also include the screwdrive AF feature, in order to AF with the three FA limiteds.

---------- Post added 05-11-17 at 11:17 AM ----------



I think Ricoh could develop a mirrorless FF K-mount within one of two years, most of the R&D would be about on sensor AF performance and video performance, they have all the other key technologies: just another K1 but no mirror and a EVF.
Starting FF would mean the extra bulk of keeping the K-mount wouldnt really matter and the price tag could be higher.
And it would strengthen the overall appeal of the K-mount.

It is a closed system. Effort expended to improve video by definition means something else wasn't developed. To the extent video development impedes stills features development - say, lenses, or an AF sensor that fills the FF image circle, or predictive tracking AF algorithms, or faster WiFi + apps, or tethering, or flash triggers, or, or, or - video development is inefficient.

Video is a priority. It's just a lower priority than everything else.

Sony A9: is there still a future for DSLRs, and Pentax mirrorless suggestion

Serious speed: Sony a9 real world samples gallery

It's been a long week since the Sony a9 announcement, but now we're finally able to show you our real wo...




With this advance in mirrorless technology, Sony is challenging Canon and Nikon pro sports machine gun DSLRs.

And IMO it also challenges the future of the whole DSLR market.

If Sony wins the high end sports pro market, within a few years, when this technology will be available in more affordable models, like $2000 FF bodies or $1500 APS-C, DSLR market shares might collapse as fast as film photography 10 years ago.

I hope Ricoh Imaging will be able to offer a future to Pentax to survive to this challenge .

Hence my suggestion of the development of a FF mirrorless K-mount: no adapter, having a thinner camera doesnt really matter for a FF system, what matters is to rely on a well established modern lenses echosystem.

In such a move, it would be useless for Ricoh to spend any more R&D on improving OVF PDAF, the urgence would be to develop from scratch a working on-sensor PDAF: it wont need to perform as well as SonyA9, but it must at least equal Fuji APS-C or Sony A6500 AF performance.

When this technology will be available in entry level ILC cameras ($500-$1000 APS-C or M43 with kit lens) and advanced 1" fixed lens cameras ( $1000/1500 pocketable and superzoom bridge like Sony RX100 and RX10), and once the pro level gear will have switch to mirrorless, entry level Canon and Nikon DSLRs might also be wiped off the hobbiists market.

That was the heart of my topic:

Ricoh Pentax is a small company in the decreasing ILC camera business.

They cannot, afford to have too many ILC systems, and they face the fast improving performance of mirrorless systems even in high end pro gear. Even Nikon failed, only Canon is big enough and profitable enough to do so.:
-Hasselblad and Fuji medium frame challenge the 645Z system
-Sony A9/A7 system chalenge the FF DSLR systems
-Sony A6*00, Fuji and M43 challenge the APS-C DSLR systems
-1" fixed lens cameras are challenging the lower tier of M43 system ILC

IMO, the question is not whether Ricoh-Pentax will have to move towards mirrorless to survive in the future.

The question is when and how:
Too early, could ruin them, but being too late to the party too.
A too bold move could mean very few sales for two or three years, yet having to fund high R&D and marketing money to settle the new system.

They always have had a very conservative and slow innovation pace, because they cannot afford boldness like Sony does, and, as Ricoh is restructuring its main business, I dont believe this might be different tomorrow..

That is why I was reckoning whether their first step into mirrorless might be an enthusiast/advanced mirrorless body in K mount, with KAF-4 features (electronic aperture support) but also, like in K1, an aperture lever and screwdrive AF ability to benefit of the whole K mount echosystem, and being able to operate all Pentax glass ever made without adapter.

Mirrorless allows easy manual focusing on legacy glass, thus postponing the urge to develop new lenses.

Some will of course complain that it would not benefit of the smaller size a new flange distance might allow, but for FF cameras the benefit is not so obvious, save in the 35-80mm FL range: wider lenses dont really benefit of a smaller flange distance, as digital sensors require to avoid oblique light incidence, and telephoto lenses need anyway to be long. Also FF ILC adress a different market segment than M43, Fuji APS-C or Sony A6*00.

But what would be decisive is that it would really need less investment, most R&D being focused on on sensor AF performance, and avoiding to cannibalize the K1 and D-FA lenses sales (if Ricoh-Pentax moves to a new mount, K-mount sales would immeditely collapse).

No need for massive advertising, just another FF body in K mount, aimed to compete with the Sony A7* (Sony A9 being in another performance league and price tag, targeted at pro shooters and needing a world wide pro support service).

This new body would generate lots of buzz on the web, thus no need for expensive advertising.

It doesnt need to be cheaper than its A7 competition, and, if Pentax can offer the same performance as the latest A7 models, even at a higher price, it could beat it on WR, ergonomy and handling, which are Pentax main force.

The move towards a new mount could be postponed a few years until Pentax will have sold enough FF Pentax K cameras, both K1 and this new mirrorless which could appeal to both the K-mount users, including K1 owners, and to newcomers, as an alternative body with different features, and of course a much better video experience.

I agree: focusing Pentax MF legacy glass at f1.8/f2 using K3 OVF is a pain, even with an OVF magnifier.
On a M43 body with cheap adaptor MF is as easy and faster than it was in the film era with split screen stigmometer and microprism, and much more precise as you get up to x10 focusing loupe in the EVF, whether full screen or local. And the results are very sharp. Thus I trust it must be even better on A7.

rumored Pentax mirrorless camera - something between K1000 and K-01

There is some temporary degeneration at work I think. The forms of current DSLRs with good grips have not evolved over time from the poorly designed cigarette boxes of old times for no reason.

The grip of a K-3/K-1 is just perfect for anyone who wants to hold a camera longer ("enthusiast") with comfort.
And part of the reason is that it is about 7 cm deep.
And that is deeper than the FF body between mount and display.
So whatever space you can save on a mount does reduce the overall z-axis camera dimension by ZERO if you do not want to tolerate a sub-par crippled grip such as you have to on pretty much all modern mirrorless cameras.
Olympus, Sony and Fuji have poor and sub-par designs there. Only Panasonic and Samsung (when they were in the game) had learned that lesson.

I do predict that those makers slowly over time revert the degeneration and build DSLR style/size bodies again for the enthusiasts. Look how Sony improved the size to larger from a7 to a7r2.Compare camera dimensions side by side

And then compare the depth of a mFT camera versus an APSC DSL: Compare camera dimensions side by side. No differences left.

This also is one of the reasons, why so few enthusiasts ever have gone fully mirrorless, but always keep a second "real" system. And it is limiting their growth to stagnation.

If you are a "casual" shooter = upgrader from a smartphone with only a kit lens or two and take less than 500 images in a year obviously ergonomics requirements are irrelevant and you can go for any exterior design that looks good on your bookshelf. Since Fuji seems to cater mostly for the style geeks and retro grandpas with a wish for photo toys and not for any serious photographers, they are most likely to continue to focus on outer looks with priority over usefulness. Actually rather surprising you can not buy Fujis in a bling-bling swarovski edition.

This thread has grown since I last visited it, and I haven't read all the intervening posts, so please forgive me if someone has already raised similar points. Am I the only one who would see no problem in a mirrorless camera with a similar size and form to current DSLRs, particularly the Pentax K-3, which I find a very agreeable size and heft? This would make retaining the K mount a no-brainer. I haven't held a Fuji XT-2, but from looking at one in a camera store window, it doesn't seem much smaller than a K-3, apart from the thickness of the body, and one needs to add the battery grip to get a fully functioning camera it seems to me, which greatly adds to its size. I bought the Olympus M1 and M5 a couple of years ago, and although they were reasonably capable cameras, I hated them for their small size and fiddly buttons. I don't have large hands, so that has nothing to do with it. Perhaps a DSLR-type mirrorless would be a hard marketing sell, but I would love to see one.

You are not alone. Leica made a huge mirror less; Olympus' latest model also has a SLR style grip.
As long as the sensor is still flate, and each pixel is still well type, the best optical design is still having a reasonable register distance to make light reachs sensor vertically. Cutting thinkness on camera and adding it back to lens is not a very good idea.
