This thread is a very bad thread idea. Imagine Ricoh have almost finished the design of the new camera. Now they read this thread and realize they will include a new feature that Pentaxian say they want, then have to postpone the new K release far into 2020 / spring 2021 so that to modify camera design / firmware to include new features.

Pure OVF and ES aren't exclusive. AE sensor allow for high light clipping indicator, as well as refined exposure metering and ETTR metering, EVF / hybird isn't not needed.

The Pentax-K-New is can't fit any category since it is a continuously morphing animal, now named K-2, but recently known as the Pentax Kentucky Fried Chicken (K.F.C) model.

I've done video recording with my K1, and given the results I got from it (using proper video setting), I've found that the core skills for making compelling videos is the choice of subject lighting, environment, focal length, quality of echo free and noise free audio is extremely important, the sequencing of video shots and managing transitions (assembling the whole video sequence itself with sound sync out of multiples shots). And so I really did not understand why people complain about Pentax video, unless people use inappropriate video technique.

Lean. I hope that Ricoh don't had every feature ever invented for cameras for the last centry, if so, the cameras would be clogged and unusable.

DNG = great.
Astrotracer - great
Pixel shift , no so much.


Yes.

1) Remove pixel shift competely, instead of PS, introduce ISO50 and ISO25 RAW frames auto-align, with both SR or ES on tripod (increased IQ and DR, but no PS artifacts anymore).
2) Fractional exposure steps down to 0.1ev instead of 0.3ev.
3) Fix unstable connectivity between camera and phone, allow thetering on phone not only in single shot mode but also all other drive modes and including remote control of camera by phone also in video mode (phone = replace tilt screen on camera, also replaces IR remote).
4) Full time ES even with OVF
5) ES available in all drive modes (HDR, composite, interval, and bulb composite)
6) Programmable shutter time delay (from 0.5s to 30s) instead of 2s + 10s fixed.
7) Highlight clipping indicator in OVF
8) Automatic ETTR mode option of exposure program, available with both OVF and LV modes
9) Optional exposure program setting with SR enabled: shutter-speed to FL ratio (1 stop, 2 stops, 3 stop and 4 stops options) when SR is enabled
10) Aperture bracketing (like it was on K5)
11) Focus bracketing
12) Ricoh should get rid of PEF. Every camera maker should align to deliver RAW files in a standard DNG format, saving costs of Ricoh itself and also saving cost to third party image software makers.

P.S. : Pixel is a good method in the lab, but always fail in case of motion in scene. Motion detection recovery vs noise, has no solution: either motion detection is exact but the pixel shift benefit is eliminated in that case, simply because every pixel information is corrupted by noise, which makes it impossible to fully distinguish if something moved in the scene or if there was noise over the same pixel compared between frames. So, practucally pixel shift is a hopeless solution to making high resolution images for all images that may have moving elements. That's why Ricoh should get rid of pixel shift completely.

Since I discovered that I can easily clean the lens mount plate on the lens side and on camera side, I never had a single occurence of AF issue. I clean the mount of all my lenses and camera body side, twice a year, and every time the cloths collect some grey/black dirt. I discovered that mounting and unmounting lenses produces residue over time. Cleaning lens mounts once in a while is good practice and it's free.

That's a case of failure for non-use. In the case of mirrorless, you were referring to failures induced by thermal cycles, which can be reproduced with thermal cycles applied externally.

Really? Don't electronic manufacturers perform accelerated aging tests on their designs before releasing those designs to market?
Would camera manufacturers just put products to market and then see if they need to grow their after sales / repair department depending on the amount of customer returns?

Longevity isn't a problem on MILC cameras because all models of 2018 will be obsolete by 2021. Sony understood that rapidely with their Sony A7 series, they moved to China for the manufacturing, since reliability isn't relevant when camera products are made obsolete every other year (even a $3500 camera). The trend with cameras is increasing prices of already expensive devices of consumer grade quality.

The problem with autofocus tracking, is the type of leading edge tech that's needed to track correctly, everything less than leading edge will struggle on tracking and while being good enough for any other type of photography.
There are maybe 5 camera models that are deisgned for good tracking, the 1Dx, 7DII, D4, D500, A9, everything else is more or less mediocre at AF tracking.


That's clear that if someone buy a K1 for shooting sport, it's never been designed and advertised for shooting sports.

I've used a Sony A7III, Nikon Z7 and EOS R (performed a number of AF routines and took a few test shots) , and they were were good. What's the problem with Nikon Z and EOS R cameras (beside reputation from biased reviews)? If I'd get a mirrorless ILC , I'd take the Z7 or EOS R over Sony, just because the Sonys are great in reviews and spec sheets but not that great when handling them.

IMO, the demand for mirrorless isn't more than DSLR, it's all under the enveloppe of ILC cameras. When Canon and Nikon and Panasonic join the mirrorless offering, they actually contribute to stimulate the global demand for mirrorless, but their problem is to compete with Sony of complete offering. Typically, when Nikon/Canon advertise mirrorless , their customers about to make a purchase decision innevitably look at Sony offering. So the key to long term survival for Canon, Nikon and Panasonic to close the gap of lenses they have relative to Sony, as quicky as possible. So that to avoid Sony to collect customers from Canon, Nikon, Panasonic. Closing the lens gap with Sony requires heavy R&D, since Sony FE lineup is already built. Heavy R&D for Canikon means they will suffer for a couple of years, only to prevent Sony to capture most of the market. Canon and Nikon started MILC too late, increasing risk of failure, and that's why Sony exec invited Canon and Nikon to join.... Sony exec knew his chance of ripping advantages when Canon and Nikon enter their market without having an adequate lens lineup.

MILC isn't that risky for Sony, since their have built up their FE lens lineup for a long time, there is a know number of FE mount lens users out there that Sony can rely on to sell new camera models. However, making a U turn from DSLR to full MILC lineups is a super risky decision for Nikon and Canon. If Nikon and Canon fail to get market traction for their new product lineups (Z and RF mounts), they'll be in serious trouble. Canon and Nikon may end-up badly hurt and completely behind Sony in terms of revenues and earnings. Ricoh can keep Pentax on the back burner, observe how sales are doing, and decide what to do once the fog dissipates, they'll have taken zero risk.

Pentax is the only brand that offer a 36Mpixel (@ Sony sensor IQ) full frame camera such that you can almost buy two Pentax bodies for the price of one body from competitor brands. That's why I induldged myself with a K1 mk II.

We're now well into 2019, one year after the full frame mirrorless frenzy of Photokina 2018 where five new camera models (Z6, Z7, S1, S1R and EOS R) were introduced to the public, along with the death of DSLR prophecy.

Looking at the trend of activity on forums around mirrorless, looking at images posted in Flick and 500px, as we more forward in time, the FF mirrorless revolution sounds more and more like a "damp squib" (also known as "Pétard mouillé" in French), a metaphore that illustrate very well what's happening, in other words: a failure to revive camera sales.

Like a lot of fads, market research reports always predict from the present moment that the future will be bright , showing exponential growths in MS Power Point bar charts. A year later, we have photographers like Matt Granger pulling out his gear on a table: two D850, two old Nikon apsc DSLR, a bunch of fast Nikkor lenses designed for DSLR that have no equivalent Z mount lenses, along with a Leica manual focus camera from a few years ago with a kit of old Leica lenses.

So it seems the famous mirrorless revolution has kicked-off like damp squid in a globally depressed camera market. The mirrorless buble slowly deflated to a point were the perceived advantage of mirrorless over DSLR is now insufficient to entice DSLR owners to replace it with a mirrorless model. And since state of the art mirroless models aren't able to produce better imaged than previous generation DSLR, things don't even look good for 2020.

Camera makers will have to re-consider their understanding of the market in order to come up with a better idea to make us upgrade our current systems....

I've decided to use the K1 with heavier glass (DFA150-450) shutter speed is almost always faster than 1/200th, and use the DFA28-105 on the K1 II.

I've never understood the purpose of using a different format as a backup camera. The backup of my K1 is a K1 II, if my K1 needs repair I can send it for repair and keep shooting with the K1 II with the lens lenses, for me it would make no sense to use a K70 with full frame lenses as the FoV would be completely different.


If you are looking for a backup body to your K1 II, get a K1.

---------- Post added 09-11-19 at 06:04 ----------


This makes sense. I have configured my K1s with the exact same menus and user modes, so that I can swap bodies and immediately find settings without thinking about it.

---------- Post added 09-11-19 at 06:06 ----------


IMO, $1400 is too expensive for a K1 used. I was offered to buy mine for $800 ! Maybe you could ask for a lower price.

My K1 mark II is not a K1 upgrade. I have two bodies, one K1 and one K1 II, both purchased new from Ricoh, I have compared the same images taken with both bodies and the same DFA28-105 lens, K1 images are blurred, K1 II images aren't blurred. So there is something with the shutter block of my K1 that's not the same as the shutter block on my K1 II. My K1 makes a more distinct shutter noise than my K1 II, the K1 II sound is softer.

IMO, the K1 upgrade of the mother board is not exactly the same as buying a K1 Mk II from Ricoh factory line. Or... my K1 is a deviation from the K1 standard quality , explaining why some K1 users noticed shutter shock and other didn't with the copy of K1 they own, also possible.
