Pros: Dynamic range, ISO sealing, image detail, controls, construction, compatibility with all K lenses

Cons: AF

Opinion: Some time ago I took part in a portfolio reading with photos of the genre I would say "reportage - landscape", BN 20x30 prints on normal glossy paper, the reader at a certain point asks me "what kind of medium format camera did you use to have this detail?" The answer is Pentax K1. To this we add extraordinary dynamic range, really sees in the dark and excellent ISO sealing. Then all the Pentax goodies, from the sturdy construction (but not very heavy) to the tropicalization (it works, fortunately) the controls in the right place Pentax style, the stabilization, the viewfinder... Let's get to the weak points... Every now and then I forget what it's made for and I try to use it for more or less "dynamic" shots... The autofocus is poor, in terms of speed and accuracy, even with "star" lenses and in some cases it is frustrating. I shoot in raw and mostly convert to BN, but sometimes with color I have a little more difficulty than other cameras in finding the "square". Every now and then I think about getting rid of it and selling it, but when I use it I change my mind. A real shame that Ricoh forgot about this machine, it deserves a sequel.

Pros: EXCELLENT REFLEX PRO

Cons: FOR ME NOTHING

Opinion: As for the firmware I download them from foreign Pentax sites, . USA. GB ecct, currently you can download version 1.55 I have version 1.54 but I already have on the computer the v.1.55.I have no problem. The updates mainly concern the use of the new optics and the general stability I hope it will help you

Pros: - 10 Impressive dynamic range of 14.6 EVS. - 9 Perfect resolution to handle (36mpx). - 9 Superfine detail (optics permitting). - 9 Rich and "deep" colors.

Cons: Firmware with functions full of flaws, no longer updated (HDR and Pixel Shift of amateur calibration). Autofocus is usually inaccurate or slow to understand (optics depend). Video compartment exceeded (max 1080p 60 interlaced, not even progressive).

Opinion: The Queen of the Night. I had in test several Reflex and ML full format but none has bewitched me so much for its ability to recover lights and shadows and to shoot in low light ... She, for me (excluding of course the new Sony A-1 and the Panasonic from over 2500 €), taking into account the price of the used, is the "Queen of the night", comparable if not superior for night seal to the A7RIV. If you have the right technical and theoretical bases it is possible to have shots with sharp lights and shadows rich in detail even with a single shot (as far as possible with almost 15 stops). Obviously it is not easy to tame: it claims "quality" or "unforgiving" optics, coma and aberrations are around the corner because its sensor pulls out of the lens 100%, as indeed all full-frame, but in particular she multiplies any defects / merits of the optics. When you do the post production of the RAW of this machine there are no surprises of dominants (optics depend.). But what you have to take into account when you buy it is that it is not a "sports" machine ... The autofocus (always optical depend.) is generally slow and inaccurate and, combined with a mediocre burst leads you to miss about 70-50% of the shots in case of motoring, motorcycling, football etc. making it unsuitable (but not impossible to use) to the action and compensating a little but not sufficiently, these defects with the stabilization of the sensor. It should not be forgotten that it is quite heavy and combining it with bright telephoto lenses means getting tired a lot. Fortunately it has an exceptional ergonomics that reduces a lot the impact of the weight but its place is the tripod, a good one! The video sector I do not judge it either, because it is NOT a machine dedicated to videomakers, although it has an almost useless audio input and the stabilization of the sensor that if it had been combined with a more recent video resolution would have paid off but would also have raised the price. What I heavily criticize is the support for the firmware update, abandoned for quite a while now, the machine in the functions has several defects that should be fixed: the number of shots in Bracketing stops only at 5 (and not at 9 as in Sony), while we have 3 useless HDR modes badly calibrated that return useless files and false colors, except perhaps one (I do not remember which one) a little more realistic than the others, but nothing serious or usable professionally (there are Smartphones that do much much better). The Pixel Shift despite its two settings, is another of its dangerous functions, made me throw in the toilet some important shots , cause mosaicization of some details, so, taking into account that we already have 36mpx what the hell is it for I do not know, better not to use it. Finally I can say that it is a machine of excellent quality, solid, tropicalized, it is the machine of the landscaper and the naturalist, I could talk for hours about her, it is a machine that when it came out dictated the law, but it is a pity it has not had a worthy evolution given that the MKII is practically IDENTICAL.

Pros: ergonomics, viewfinder, construction, details, stabilization, tropicalization... in short, the usual pentax things before they were discovered by others to become important. A real pleasure of use.

Cons: To date I do not know, too soon to say, I will update aware that probably the known limits do not concern my uses.

Opinion: For a while I was behind him and in the end the right opportunity came. Usually aware that a review would require use and practice of a few months, since the room has been out for a few years (and also production) I will limit myself to describing some aspects and sensations that have emerged to me immediately. The grip and ergonomics is pretty much perfect for my hands; the body is obviously heavier than my apsc models but it remains very balanced even the use with one hand (I do not have heavy lenses). I will use it practically are with "small" fixed (which I will add slowly for this year I gave) and I'm curious to see how it will be used for street photos from a practical point of view. Seeing inside the viewfinder, coming from apsc (and pentax already has excellent sights about it) is really a pleasure and the jump is remarkable. Coming from the pentax world the menu and functions are really intuitable even without reading the manual, which you have to resort to only for some peculiarities of use and functions. It ran all quite quickly and modified according to my preferences I tried in review the various lenses I have, both in crop and FF mode. The basic idea is to glue on the 31, however I have to understand well also the relative lower (and upper) angles of field. I therefore tried K, M, A lenses of various focal lengths, as well as some DA (12-24 and 55-300). First of all, the position of the green button for stop-down measurement is really convenient. Unlike my apsc which was above on the back and I could resort to the index only (first to measure and then to shoot) now being on the back I can use the paired thumb (to measure) and index (to shoot) almost instantly and without moving anything. I had read information on the DA 12-24 on the net I think I can confirm that from 18 to 24 the DA is usable without particular problems, with slight vignetting starting from the minimum limit with a tendency to improve by going up and closing diaphragms, and for me it is a good thing. I tried out of curiosity (these days it was talked about in a topic) the electronic shutter in LV (unlike later models it is not usable in the k1 viewfinder) and is quieter but not completely silent (as I imagined). I must say that the noise of the mechanical one is for me very low accustomed to the shooting of the k30 and also to the noisiest of the k70. Also interesting is the solution for the junction of the LV which, although different from that of the k70 is equally appreciated by being able to use it, overturning it upwards, even in the way of a cockpit. The seller has also included in the price two SD cards so I will have the opportunity to immediately appreciate the double slot (although I do not consider it fundamental) since I will use among the options the one that directs the jpeg on one (before I only shot in jpeg) and the raw on the other of which I will be able to keep those rare cases that interest me. I bought this room for whim and not for necessity, although I seem to have noticed immediately that the diversity of the depth of field at equal aperture between apsc and FF is quite evident and may be important in certain situations of portraiture. I have not tried astrotracer (I do not even know if I will ever use it :), the pixel shift (the k1 has no motion correction) but above all the wi-fi connection with the App (which I already had for the k70). For the rest there are more detailed and complete reviews, comparative even with the k1II and the topics covered are quite exhaustive. The room is new (not equal to the new but just new), I wonder how do you keep the rooms in these conditions, I will work to consume it a little ... :)

Pros: Quality of materials, attention to construction and details, compactness in size, lighting of the interior compartments, optical viewfinder, dynamic range...

Cons: AF in Live View in dynamic contexts.

Opinion: Albertoscaccia, in his 2018 review, wrote: "Photograph by candlelight at night and manage not to throw away even a shot: this is the k1" and even today it is impossible to blame him. A machine built to last (the shutter is tested for 300,000 shooting cycles), with the back covered with buttons and buttons that leaves the photographer the opportunity to concentrate completely in the photographic act. The viewfinder is bright and vivid, it almost seems that it is not there. The size makes it akin to non-pro products and this can be deceiving. The sensor, 36 MP, offers an amazing dynamic range superior, say, to that of the Nikon D810 that allows the device to express all its potential in static contexts for which, among other things, it was most likely conceived: astrophotography (it has built-in GPS with astrotracer function), landscape, still life to name just a few. I, however, use it almost exclusively in a dynamic environment (reportage and events-when there were ...) where it manages to express an incredible quality and refinement of the files: it grows more and more and continues to emerge detail. Pay attention to the density of the sensor that can cause micromosso in freehand shots. The machine pays the shame of having 36 MP at 4 fps that require appropriate tools: cards with high writing speeds, capacious hardisks, PCs suitable for post and processing files are all aspects to be carefully evaluated before purchase but, I think, completely usual for a professional or an "evolved amateur". Unique, at least for me, negative aspect is the responsiveness of live view in dynamic contexts where it expresses its gaps and makes it almost impossible to hook and grasp the subject, if not after a few failed attempts. The K70, which I kept as a second body, in this case is superior to it. I plan to take another K1 shortly, as a second body, so enraptured by his files. There is talk of the EXCESSIVE weight of the K 1 (without saying that it is designed to be perfectly balanced with the optics starting from the 24-70) but the others, what do they do? Canon 5D Mark IV 890g; Nikon D850 1015g; Panasonic S1R 1016 g (yes, mls also have :) defects).
