fPrime: Very in tune with the trend in lens design these days... big, heavy, sharp, and well corrected but with relatively flat, characterless rendering.
You need to try out the Pentax FA77/1.8 Limited :) Pop and 3D there for the asking. Trouble is a lot of posters go by numbers and not the returned image.
Are you basing the poor low light AF when combined the the Sigma ART lens? I.e was it more prevalent when used with Sigma rather than a genuine Nikkor?
Calvin Chann: Don't know why existing Pentax owners are the main target. It's not as if they have a lot of full frame lenses to use coming from crop sensor DSLR's.
I see this more as being a new DSLR aimed at any previously brand loyal photographer.
What Pentax need to do is to ramp up FF lens launches.
From old to new: Takumar, Super Takumar, K Series, M Series, A Series (these have auto aperture on K-1), F Series, FA Series, DA Series (Crop typically), D FA (some of these are FA type but optics tuned for Digital)HD is latest coating replacing SMCSome of the series have a * designation, i.e. A* 85/1.4 or FA*200/4 Macro - These are what Pentax would deem top of the line optically. There are also different sub types within each series, notably the FA Limited or DA Limited, these will have a certain character, i.e. with the FA Limited's the design brief was to return an analog type rendering, the DA Limited's would be about small size and good performance from the widest aperture while keeping up to date with rendering fashions.
Terkwoiz: Amazing camera and great price. After reading through the comments it's clear that there is a lot of interest from current non-Pentax users but a main concern seems to be lens availability/affordability. Also concern whether the available lenses will be able to handle the demands of the sensor (ie: not originally designed for film).
Can any of you who know please list the best lenses available for someone who is interested in buying this k-1? I currently use Sony with 25mm, 35mm, and 90mm. I was thinking about getting the new Sony gm zoom but now I might switch over to this system 😄.Thanks!
25: Hunt down the FA*24/2 or Zeiss 2.8/25 ZK or wait for new Pentax wide aperture wide angle on lens roadmap35: FA31/1.8 Limited or Sigma 35/1.4 ART or FA35/290: FA77/1.8 Limited, Tamron 90/2.8 macro or hunt down FA*85/1.4 or Zeiss 85/1.4 ZKThe Zeiss lens will be manual, Tamron is sharp across frame whereas the 77 and 85s will be more for portraiture.The 31 is classed as one of of not the strongest all rounder lens in the current Pentax lineup with above average resolution and rendering, the FA35 will give you 95% for a third the cost. The Sigma is big, has its fans if you prefer sharpness overall buy there have been reports of inaccurate AF across brands.
Hahaha, you don't know the typical Pentaxian that frequent either here or Pentaxforums. I'll give you an example, I have 7 K mount lens, 2 are limited to crop sensor (Zooms DA*16-50/2.8 & DA*50-135/2.8), the rest of my lens kit are all FF and from what I can gather will be very capable of producing excellent images with the K-1 and I have 3 more to get in before I get the K-1 for Christmas. Compared to some, I am a lightweight in the lens collection game.A lot of Pentax owners will have dipped in and out of the pretty broad range of previous FF lens series (Takumar, K, M, A, F, FA, DFA) to accumulate lots of FF lenses, all waiting for a FF body.
Kostasm: Amazing performance indeed. So bad though there are no equivalent to the sensor lens options at the moment. Visible CA ruins the perfection. Just image how an Otus lens would perform in pixel shift..
Have one, a Leitz Weitzlar Makro-Elmarit 2.8/60, performs beautifully on my K-3 with a quite distinctive rendition. Bit of flare monster if caught with side light though :)
CaMeRa QuEsT: Hope all this and the K-1's selling numbers are compelling reasons enough for Sigma to port all their ART lenses to K mount, that on itself will be a real boost for K-1 sales, at least that will convince me to get a K-1.
So your bokeh can be sharp? :)) Sigma lens seem to bench well but they lack character and feel in their rendering. It's an intangible thing that is difficult to measure but it is one of the reasons that the three Princesses are so beloved by their owners. The Princesses being the FA31/1.8, FA43/1.9 & FA77/1.8
Your point being that Pentax have released a Full Frame camera for £1,599 and to do it justice you think they need to mount a lens costing £3,000+? :) I'm thinking a bit of a bargain for this body. If you need a flat plane of view, that has good resolution, low CA, then Pentax have the DFA50/2.8 Macro - Photozone was quite impressed with it when they tested it recently, and all for less than £400.
nicolaiecostel: I thought Limited Pentax lenses were the best ever, as claimed by pentax aficionados.
@nicolaiecostel, not at all. Thanks for asking. I'll let you in on a secret, perhaps you should try mounting your lens on a camera? I can only presume that it would induce less hurt in the area you describe. A link for you to read:https://luminous-landscape.com/sm-02-05-02/
Yep, they are :), now f off and troll somewhere else.
420deimos: Nice write up, Carey understands...
I agree give me the K-1 and a 43 f1.9 Limited and who needs much more...
43 is the perfect normal. Small, light, fast enough, excellent contrast and sharp where and when you want it to be. One of the ultimate reportage lens designs.
Kostasm: Pixel Shift function looks impressive and quite fast. Some Zeiss ZK lenses is all we need and we are already there (we, NOT the Pentaxians)
Some Pentaxian's will already have some Zeiss ZK glass waiting for playtime on the K-1. That being said, more would be preferable, especially in the wider prime area with the Milvus 2.8/21 and Classic 2/25 being stand outs for prime users.
Nicely written piece. The most important paragraph describes with whom this model has been developed for, namely the loyal 'Pentaxian'. If you frequent the Pentax forum on here or on other sites, one thing that you will notice almost immediately is the sometimes staggering amount of lens that quite a few have in their possession. I've trimmed down quite a bit but have a pretty good idea of which optics will be capable and which will be less so. You are correct in that if you wish to fully experience the quality of this sensor then the easiest way will be to pick up the 3 fast zooms and the super telephone zoom. I say easiest but not the only way, the FA Limiteds, the DFA macros (50 and 100) are stellar optics and can go toe to toe with any equivalent competitor and come in exceptionally small packaging. Previous highlights would include the FA* teles such as the 600/4 and 200/4 Macro. In MF I would highlight the A*85/1.4 and A*135/1.8 and the A50/1.2, going a bit older the K50/1.4 has a distinctive look all to itself and the K28/3.5 and K35/3.5 will surprise you with edge to edge resolution. Coatings wise, an SMC lens will be equivalent to a Zeiss T* of the same generation. Half the fun of being a Pentaxian is searching out, and then understanding these gems which have fabulous character.
Perhaps the 'Very Expensive' for its class should be reassessed? Pentax was just early to the high end 50 market by about 3 or 4 years :) See Zeiss OTUS, Sigma ART, Nikon 58....AF is also excellent with K-5 (K-5II or K-5IIS), K-3, K-3IILastly, it is also FF!
Robbie Corrigan: Negativity on here is astounding. It is a teaser site, mainly highlighting lens compatibility (FA*s 24 & 85), FA Limiteds 31, 43 & 77 and DA* 55 & 300 in FF and APSC mode + lastly the DFA24-70/2.8 while at the same time close ups of the body and dial / button layout. Pentax are not showing or releasing full raw files as of yet, these shots are showing off proof of concept, i.e. a K mount with digital FF sensor and various AF lens, screw driven (FA's) , old SDM (DA*s) and new SDM (DFA). Opinions on marketing, sales volume, market share are a complete moot point as it already has a very loyal captive market already waiting for it - the majority of whom have a lens arsenal to throw at this camera. The teaser shots are probably just wetting the appetites of some purely because they will want to see how well their particular example of said lens will do in their own hands. For me the first lens will be the 43/1.9 followed by the A50/1.2 then probably the 77/1.8. See its 'when' not 'if'
Thats just showing off :) - Would love to know just how many 4/200 Macro's are out in the wild. Its on my list of 'Wanted'!
brownie314: I really don't get this product. It is totally "me too" in an already crowded market. Pentax (Ricoh) had something unique in the gr. Why not try a ff version of that bad boy? Love it/hate it - at least it would be different.
It is a loyalty payment to Pentaxian's who want a FF version of the K-3 :) - Market is not crowded, it is captive, waiting with baited breath.

robbo d: This will slightly stimulate interest in Pentax.
What's needed as per anu l said below is lenses. A huge consideration after the 24-70 and 70-210 is a 24-120 like Nikon's. That's a deal breaker for me .... not sure my old FA 28-105 will cut the mustard.Perhaps Sigma's 24-105 will come out in a Pentax mount ....that would make sense.
There is a DFA24-105 on the Lens Roadmap :)
Robbie Corrigan: Ahh just so you know the 31mm Limited is not exactly a small lens. Compared to the other Limited's it is massive. So based on this, this prototype is a couple of mm wider, perhaps a cm taller than the K-3, grip seems deeper so its really like a taller, tougher K20D. Its VF could well be the star of the show, 100% field of view, 0.8 or greater magnification. First lens I will mount is my 43mm Limited and enjoy a 'real' normal FOV and go street shooting. When it gets dark, I'll find an available light only gig and dig out my A50 f/1.2 and immerse myself in my own photography heaven, a system I know, a big VF, a fast manual lens and lighting I have to adapt to.
The 31 and 77 are known quantities of optical excellence (excepting perhaps the 77's foible of PF wide open in high contrast scenes). The 43 however is in my opinion very underrated, and a bit lost when used on APS-C where it becomes a 60 something which is a bit tight for its design use as a reportage lens with a 'Real Normal' frame of view. The A50 f/1.2 on the other hand is an optic to be enjoyed and mastered, with an APS-C VF, focusing is tricky to say the least and depending on your scene, nailing it is very technique dependant. Once you understand that and get in the zone, available light live gigs is a genre of photography that I adore so I am very much looking forward to the bigger VF on this new model and exploring the sometimes weird and wonderful world of faster than f/1.8 and f/1.4The 31 and 77 can have a play the next morning :)
