Right.
What many people praising the gods of pixeliated view of the world tend to forget is that this high tech, that then is called "almost as good as a DSLR" is sold in cameras for prices starting from 5000$ with the newest Z9 or the R5 up to 7500$ as for the α1. Some of it will trickle down to more interesting models, but if there is demand many advantages of DSLR can also be put further. Like I mentioned, a dedicated metering sensor that is sensitive to Infrared spectrum etc...

Yes, right. In this case AF is of no use and manual focus lenses work well. I would see the Irix 11 and 15mm lenses in the same "nice to have" class, still I would love to see at least one native lens covering these bases. Especially since Astrotracer puts Pentax DSLRs quite high up in this domain.

I would see some need in primes WA focal lengths. I'm sure the 21 limited is a phantastic photography lens with a lot of character, but for my kind of work sterile, well corrected wide angle lenses would be great. As they would be for astrophotography, a field the limited might not especially be addressed at. If the fast aperture WA DFA* is going to be 35mm f1.4 it would be great to get something like 28 or 24 f2.0, well corrected wide open for astro, architecture, landscape and technical photography...

That's one way how to look at it. Another one is that there are 5 lines of FF lenses.

1.

HD 21 f2.4 limited
HD 31 f1.8 limited
HD 43 f1.9 limited
HD 77 f1.8 limited

2.

HD 35/28? f1.4 *
HD 50 f1.4 *
HD 85 f1.4 *

3.

f2.8 zooms

4.

variable aperture zooms

5.

non * primes


Nr. 1 and 2 are quite consistent, sure, the newest limited has a new construction, but fair enough, and it's called the first of the new series

The fast aperture WA lens will be next; agreed, it's overdue, but this trinity of fast * lenses covers high end classics

Everything else is there, I think some lenses there are highly appreciated and the overall usability is good.

Do you seriously expect Ricoh to go the same route as Nikon goes at the moment and overhaul all their lenses in one run? In which world could this be considered a viable business model?

------ Edit ------
you edited your post while I was replying...
I now see where you want to go, but still don't think that this is realistic in any way. Nikon decided to abandon the existing F-mount and wants people to spend many thousands of $€ on their new developments. Let's see how this works out...

To be truely honest, Ricoh is better of investing in a GR line with 18mm, 26mm and maybe even 35mm... I'm pretty sure they are selling more lenses with sensor there than they ever would of moderately fast non* primes for DFA...

I think you are right. Ricoh in L-mount would mean: they produce a camera that can take lenses from other companies. The existing K-mount lenses can not be sold any better than now, nor can they be produced in L-mount without complete reconstruction. A complete new set of lenses needs to be developed and by that, even for the own cameras, stands in concurrence to already existing ones in all price brackets...
I can see where the wish from the consumer side comes from, but from the company's perspective this does not sound overly attractive to me.

Some interesting tidbits from some recent articles might reveal something that industry and marketing driven (new is better profit) newspages might not propagate openly: DSLRs are not suddenly bad. There are many good reasons to keep these systems in the market, many people simply like many of the advantages they offer. Just read it here:
https://www.digitalcameraworld.com/uk/amp/news/i-wish-i-hadnt-sold-my-nikon-...an-you-realize
Or here, the title says it: Shooting experience: The Nikon Z9 is the most DSLR-like mirrorless we've ever seen: Digital Photography Review

The biggest difference that is in the foreground now is partly marketing and tech geekery hype. Sure, an Z9, or a1 or R3 seem to offer all the innovation, but it is just because a lot of development money went into that. And these companies want this money back, there go XXk $ for a camera with two-three lenses (that are also excellent, but so are new DSLR-lenses that came out the last two years).

I just found it funny to read the article about d7200 nostalgia. My mind just wanted to ask: really? No shit Sherlock...

Well, funny thing is, this kind of view of "advancement of technology" is really so detached from photography that it just makes me shake my head at these postings. Dpr ... stated that the A9 sensor is leading class within its peer group. When looking at the comparison of images they are so close to 10 year old sensors from K-1 or D850, if they even reach their resolving power and dynamic range at all. The advancements are in video and in speed and in the comments Dpr staff commented that they meant "class leading" should be read as "not visibly behind" those other sensors.

Another thing is the whining about things that could "never be achieved " with OVF, mostly related to AF, often in connection to scene analysis, AF coverage, object recognition and tracking. Yes, there will be differences, but as Kunzite pointed out, by getting rid of the secondary mirror after the semitransparent main one the imaging sensor could also be used for on sensor AF in an OVF system.

But an often overlooked technical advantage of the system in use now is:
The use of a dedicated metering system for both AF and exposure brings the problem of resolution (number of AF points and pixels for metering and scene recognition) and coverage. However, a dedicated RGBIr -sensor provides the system with another layer of information that a mirror less simply doesn't have: Infrared is very useful to identify pupils of living objects and thus often used for eye tracking etc... it is a coarse and grainy layer, but can enable such systems to track eyes almost in the dark...

I'm with Kunzite, this seems a weird approach that a bold statement can be seen as valid without proof because it would need insider information to have that... wanna buy some Squid coin from me, they are a great investment... ;)

While we are at that, I really would want this lens to be overhauled and brought to high resolution APS-C sensor standards... and here I mean sterile technical corner to corner sharpness. The system needs a wa-lens for documentation photography.

Someone riding the sunshine road?

I liked Contax, but they were not this German producer catering the homemarket before they left the race. They belonged to Yashica that became a part of Kyocera in the 80s. They dropped the ball with the development of the FF digital camera, that they could not sell because of poor performance.

However, why is this thread discussing this at all? Some obviously need their daily dose of negativity.

Yes, good question. Considering the translated text it might be optimised for corner to corner sharpness at far distances and rather closed down. This could give it a more pronounced sharp center wide open and closer. Would be fair, either isolate object in center wide open or have architecture/landscape/(astro) somehow closed down.

I also assume it is not field curvature. The second berry image does not have anything in the center where the focus would be. If focused with PD-AF the berry is maybe already outside the area covered with AF points and probably had to be recomposed?

I don't assume a problem neither with the lens nor with the camera, but more a new challenge for proper AF at the very periphery of the frame, that may be exposed more than before by the high MP count of the K-3 III and the smooth transition from very sharp to slightly OOF in the lens. Things, that might have not been noticed with previous equipment.

There are two good articles on field curvature in lenses by Roger Cicala.

He explaines quite well what focussing strategy to use if your main subject and focus should be off center or other settings.

This, without offence, does not sound like a lens problem. Either you initiate a dedicated focus attempt with that dedicated point, then you should be able to see if it aquires focus or not. Or you have some automatic settings and the camera decided what should be in focus. Your statement might benefit from some exemplary images with full exif and/or a closer description of your settings and methodology.

Sure, but I would not see any need to extrapolate the performance of mechanical coupling and a tube prolonging that for screwdrive AF and apply that to electronic contacts for a modern SDM AF.
If anything could cause a decrease in performance it could maybe be an effective reduction of the focus throw, which could be optimised for performance without converter, but I think even here modern motors can handle that.

I can understand that this question comes up, but my curious mind is asking "why?".
Let's assume the sharpness and contrast are not a problem, at regular focal length they are amazing and the converter does not decrease it too much. Definitely not beyond the level of a zoom at such a focal length. The effective aperture is still at 5,6, not worse than the 560 has been. Why should the phase detection AF function any different from a regularly attached lens, if the AF-motor is in the lens and the focus group to move is physically the same? Of course there are other practical challenges to AF at these focal lengths like keeping a subject in the image frame etc.
Again, not claiming this will be produced at any time, just curious about the physical background of automatically assumed "restrictions"...

Fair points, while I still think that this is not an unsolveable technical problem today. Sure - at which price point. On the other hand, if the 560 was a 5+k lens then there is some room to start with.
But, at the end of the day, as clever as it would be, I also don't see it coming.

I'm not a tele guy, but this seems to be a very clever and effective option. One lens, two (optimized dedicated) converters to cover three tele focal lengths with faster aperture and in the 2x option more reach than the zoom, which this way would also not be cannibalized. They should definitely do that. Could this be made cheaper than the 560 has been?
