Finally Ricoh came with an excellent camera. But what should they add another, wide-angle converter to make it around 26mm. And I could (almost) rid of my Pentax gear 🤯 .

There were two other, very popular TLR cameras, about which the author is very likely not aware at all: Minolta Autocord and Meopta Flexaret. Autocord was my the most favourite camera for 40 years!

Coming form a Canadian university and not to be joke? Even that image of a lens element (oval?) is a joke :-) . Just joking as well.

random78: The softness due to shutter shock reported in the article is not unique to this camera. Other well known cameras have suffered form this as well. For example dpreview reported the same shutter shock in D780 as well:

https://www.dpreview.com/reviews/nikon-d780-review/6

Shutter shock problem typically happens in some cameras at specific shutter speeds. In case of D780 it seems mostly to be in 1/30 to 1/60s range. K-3 Mark III also seems to suffer from shutter shock at similar shutter speeds. The effect seems more severe for D780.

@ ogl. This problem was analyzed "to the death" when the Pentax K-x camera was released, as it was very prone to it. And the analysis result is following:
1. The image softness occurs at the shutter speeds between 1/80 and 1/160.
2. It is caused by the sensor movement, which permanently levitates in the magnetic field. That's why this problem doesn't disappear when you turn SR off, or cement the camera to the floor.
3. The main cause is not the shutter movement, but the mirror movement/shock.
4. For all shutter speeds below 1/80 the sensor calms down well before the actual exposure finishes.
5. For all shutter speeds above 1/160 the sensor starts to "shake" after the exposure finishes.

With the mirror lifted off those problems should disappear. But the cameras like K-x, K-30/50, K-S1/2 and K-70 can't lift the mirror! The cameras like K-5/3 can. I have the K-S1 and never experienced this mirror shock. Exactly like on my KP, as I had never had any needs to lift the mirror off.

flektogon: Three Pentax cameras (K3/3, KP and K3/2) exhibit exactly the same, a little bit softer images in comparison with the Fuji X-T4. So, it's not a K3/3 particular "problem". Did you use the same lens to test those three Pentax cameras? Because the pictures corners of those 3 cameras are alike poor in comparison to Fuji. I think that it's the lens, which "degrades" the Pentax results (in this particular test).

@ Revenant. So, why then all three Pentax cameras exhibit the same softness? Compare the Fuji X-T4 with Pentax K-3/2, K-3/3 and KP. I see three very similar images, all three softer than the Fuji's.

@random78 No, the shutter shock is usually most pronounced at the speeds between 1/80 - 1/160. At least this is the case of certain Pentax cameras (like my K-x), but no shutter shock at my K-S1 and KP. And in such cases you can even detect the direction (vertical) of the sensor movement causing the softness.

il_alexk: 1000 potential Pentax buyers, ~800 comments for a camera you can't even buy yet. Almost 1:1 ratio.

A new Guiness record, huh?

@il_alexk. So, how many companies are there, which would take such a good care about their 1000 customers?

Well, what you were doing outdoor in such a blizard and even with a camera :-) ? And yes, a fantastic catch!

flektogon: Well, get a Helios 55mm/2.0 for 1/20-th of this lens price and you won't see any difference.

Yes, you are right. It was Helios 58mm. Memory!

Vit Adamek: The closer the subject the more unique FF look, and then the high DR.

@badi, yes, you are absolutely right. FF cameras with dark lenses have no sense! But once you use a bright lens on such a camera, then no smaller sensor camera can compete!

panther fan: Having a switch to change the focus dial to aperture is a nice touch, but it would be even nicer if it also made the dial "click"

That and the missing custom button really make it second class compared to the new Sony and Sigma primes, which all come with dedicated aperture dials and custom buttons. How much would it have cost to include those?

Any clicking would be undesirable for video shooting!

flektogon: Well, Meike makes some pretty expensive (cine) lenses with the m43 mount. And they are fully manual as well. What is the difference that this one is so substantially less expensive?

Thanks Tanner_Sheppard! Well, I thought about buying the Meike 12mm/T2.2 cine lens to my grandson, such a learned about Meike lenses. Well, I have no idea how is "T" different from "F", but that lens seems very decent. However, not I am not sure whether Olympus 12-40mm F2.8 Pro, for example, is not a better solution, even though it is twice as expensive.

MonsieurAlpha: So here is how the meeting probably went down:
-Do we have the money to develop a complete mirrorless system?
-Oh I am afraid not.
-Then lets tell everyone that we think focusing on SLR is the way to go.
-Good idea!

@Foskito. But that's exactly where Pentax is heading. In a short time Pentax will become an exclusive DSLR camera maker, similarly like Leica has become (some 20 years ago) an exclusive RF camera maker. Well, it may even happen that the customers will have to pre-order their (Pentax) DSLR cameras, similarly like Leica customers are forced to do. And I would not be surprised at all if this happen.

@ Indiana Jones. So, how do you judge then Leica cameras? Even far more obsolete and expensive viewfinder where some lenses block up to 50% of the viewing area, with the prices 4-5 times higher than cameras delivering comparable results. Extremely expensive lenses with limited focal distances. And the customers have to wait in a queue to get the latest models ...

Exactly my thoughts. That's why hats off to their effort! Bravo PENTAX.

Sorry, I mentioned zakaria, because he is a notorious contributor the the Pentax forum. Like myself.

Here it is: Ricoh claims that autofocus subject tracking has been improved, without providing further detail.

I have personally never had absolutely any problem with the Pentax AF (well, not used AF-C very often), but they claim that even this has been improved. So, what else could the Pentax cameras have? Maybe a fountain? 😆
