Is the K3 truly a significant improvement in IQ over the K5/k5II?

As a lowly K-01 and K-30 owner, I can only say that how the camera feels to you is really important. I like my K-01 the most, for the way it feels, the ergonomics... even though the K-30 is a better camera with MUCH better autofocus for tough subjects like fast-moving little airplanes against that big sky. But -- for me -- the K-30 stays in the car most of the time, with a telephoto lens... while 90% of the time I use the K-01 with a 35mm f/2.4 prime.

Maybe I like the K-01 more because it has simpler controls, or maybe because it just fits my hands better than the K-30. Both have absolutely excellent image quality, and I'm sure the K-3 does also. If I were a professional, I'd buy a K-3 in a flash. Just being able to crop that huge 24 mp image would help you sell so many more pictures. Plus -- sports action on a winter day in a freezing rain... when all the Canikon guys are hiding under the stands!

But as an amateur, I have the luxury of enjoying a camera I really like, even though it just wouldn't work for a pro. K-01 for wedding photography? Not. But for landscapes and general street photography, it's wonderful...
 
I think it is important to understand the characteristics of the K5 and K3 sensors in regards to noise. Iso 3200 in low light with a fast lens and slow shutter speed will have a very different noise profile than an iso 3200 in bright light, fast lens and 1/2000 shutter speed. A shot at low iso can be noisy where a shot at high iso can be clean. There is an optimum exposure setting for each shot, and it isn't simply a matter of swapping a stop of iso for a stop of shutter speed or aperture. Low noise on these sensors is a matter of the skill of the photographer, skill that brings the best out of the sensor. As well as knowing the practical limitations of post processing software, and working within those limits.

In other words, I wouldn't come to a conclusion based on shots you see here. Nor on shots done by some defined test procedure that may or may not coincide with the sweet spot of the equipment. I doubt if anyone yet has found the sweet spot of the K3 sensor, and fewer have post processing software that has the curves and profiles that bring the best out of the sensor. That being said, I have seen some excellent results from the camera, in what I have shot and what others have posted.
 
I haven't used the K5iis, I shot the K5 for a couple of years. I got excellent results from the K5. There are a few things that were obvious limits and causes of frustration on the K5.

The AFC mode is nearly unusable.

The focus points are too large and undefined.

Processing on all levels is slow. From focus acquisition to exposure, to viewing a shot after exposure. Live view updates making long lens focus very difficult due to lag.
This thread is just taking more time to get through than I have, so I'm replying at this point. Every single point you made up to here is every single gripe I've had with MY K-5 (and I haven't bought a K-5II/(s), either, as I felt it was too much of an "incremental" upgrade and I wasn't sure if I could also make the MAJOR upgrade I knew was "coming soon" if I did. I'm still waiting for my K-3 to arrive, as I ordered the Silver LE, and I ordered from B&H, which appears to be LAST on Ricoh's delivery schedule (maybe because they sold so many?), so I can't speak for the K-3 from personal experience yet, however...
The K3 fixed those things for me. Noise levels are pretty well the same. I limited my K5 to 3200 iso and have my K3 set the same. I have shots at that level on the K3 that didn't need denoising when looking at the whole frame, as well as shots at much lower iso that have visible noise. The hard earned lessons from the K5 noise handling apply to the K3.

I have noticed the K3 getting colors in situations where the K5 didn't. Similar light, similar subjects, one has vibrant and visible colors, the other doesn't. The IQ is better I find on the K3. It may be the lack of aa filter, so the same may be true of the K5iis.

White balance is much better. My DA*300 on the K5 had a noticeable yellow cast, I did a few presets with a white card in various lights for correction. The K3 using the same software and same lens is right on.

Exposure is more consistent. The flash in my experience so far just works where it didn't on the K5.

My DA*300 feels responsive and accurate on the K3, where on the K5 it was an exercise in frustration. I figure I have what amounts to another 100mm of effective length with that lens on the new body.

I am taking shots that I didn't bother with. The K3 delivers where the K5 was an exercise in frustration.
Most of the things you address the K-3 is doing that you either had difficulty with or simply couldn't accomplish with your K-5 are the sort of things I've been looking forward to accomplishing with MY K-3, as well.
My K5 had sensor stains, and after the Pentax Canada repair shot did their magic, my lenses were accurate, the focus screen was right on. It wasn't finished at the factory. My copy of the K3 is right on.

So yes in my experience the K3 is substantially better than the K5. I can't comment on how it compares to the K5iis.
As to the K-5II, as I made a FIRM decision I wasn't going to buy one, I've never really paid much attention to all the talk on the forum about how they compared to the original K-5, except I have been aware they had sensitivity down to -3 EV (although they wouldn't necessarily FOCUS down to that level, I don't think -- I could be wrong -- from what I've read, the K-3 will also FOCUS at -3 EV), and, of course, that the K-5IIs didn't have the AA filter. The fact that the (II) series did NOTHING to address any of the K-5 focusing issues (didn't increase the number of points, improve AF-C, etc.) was perhaps my biggest reason for not considering it more, on top of not wanting to strap myself financially prior to the anticipated release of the K-3. Having read some (such as Mike) post, however, since the K-3 came out that the K-5IIs may actually have BETTER image quality in some regards, well, with the prices on those dropping, I may pick one up before they stop selling new (once that happens, prices tend to rise again -- original K-5 is now selling new for as much as or more than the K-5II again, because of its scarcity). Doing things in this order, if I do, I will have saved several hundred dollars, at least.

Finally, as to SBS and his original post (and the two responses he posted to photos posted by Mike and Greyser -- I read both threads), frankly, I agreed with Mike's response, at first. But now I see the issue. I've come across as "brusque" to people in the past, myself, because sometimes I've been too "direct." Some folks just aren't very good at being tactful, yet mean nothing derogatory by it. I suspect that's the case with SBS, at least I hope so. That seems to be what he tried to say in some of his responses above (again, I don't have the time to read any further right now). I see some folks in this forum who don't "get" humor, don't understand sarcasm, satire, parody, etc., and take a RIDICULOUS comment someone meant to be humorous at face value (maybe sometimes via a language barrier, but some folks really DON'T get humor. I've known a few). Some folks don't "get" tact. My late grandmother was like that... meanest woman you'd ever meet. NOBODY liked her, and I MEAN NOBODY, not even her own two sons... Only thing was, and I didn't realize this until the last time I saw her, just a few months before she died, she had NO IDEA she came off that way to other people. She just said WHATEVER came into her mind, with NO filter or thought of how it may affect someone else's feelings.

Actually, I think she had a mean streak, as well, but not nearly as bad as we'd all believed... most of it was simply she had NO CONCEPT OF TACT.

You live, you learn. Some folks just never learn some things.

This reminds me a lot of when the k10d came out.

Lots of people were disappointed by the high ISO performance of that camera over the previous generation. But they went for the added resolution and the shake reduction anyway. Turned out to be a great camera especially because of the shake reduction.

But man the thing did annoy me with its weak high ISO shots.

So I'm thinking the k3 is worth it for the AF, flash update, and cropping ability, focus peaking, even in video. Those are some great features if you'd actually use them.

But....I don't like the noise it's putting out at low ISO. I'm seeing noise in deep blue skies at ISO 100. The k5 doesn't do that. And I love my k5 except for the AF, it's got plenty of resolution for me.

So...sitting this round out, getting a K5IIs and selling the k5. Pentax is certain to release a camera with a sensor that clearly outshines the current 16mp Sony soon. It may be a full frame, it may be mirrorless, but whatever it is, it is bound to be more revolutionary than the evolutionary k3. And it's bound to come soon. I hope. ;-)

When the *ist-D came out I bought one as soon as I could get my hands on it. 10 years on the image quality still stands up pretty darn well.

The K10D was better in every department - bigger display, SD instead of CF , with much faster write speed, better AF, better control layout (these days we just wouldn't accept changing ISO by moving the Mode dial from "Program" to "Set ISO" and back ) and Shake reduction which I took to be a gimmick until I used it. The high ISO performance wasn't fantastic. But 3 or 4 years before I was shooting film where nothing over 1000 was any good, so I just shrugged and got on with it.

The step from *ist-D to K10D, to K7/K5 has shown improvements but frankly the change in sensor / image quality is the hardest to see. Of all the changes it's the longer DR / usable very high ISO in the K5 which I notice most, and then only for a small subset of shots.
 
The version of ACR when the K5 came out would create jpg's that at certain viewed resolution rendered a mosaic of small noise artifacts even @ iso80 .

This was not the camera but the processing.

I have seen the k3 noisy sky's in some posted images but not encountered it myself so maybe the same issue?
 
after my experience this week with higher meg count, is that IQ should be judged in categories ?
Ie : small print, large print, crop print, normal screen viewing and 100% viewing. because one camera isn't the best at them all. my 2 cents. Nikons new df 16meg to me is the best all round to date for fx and imop the k511s , but I love the new k3 upgrades, maybe a k311 with a high quality 16meg sensor ? next.

cheers don
 
Can't blame ACR for out-of-camera jpegs like the ones in the DPR sample gallery or the ones posted to this forum. That's all on Pentax. But really it's a minor point, present only in a small subset of images, and easy to fix in post. But you'd definitely have to fix it -- the noise is and/or artifacts are/is blotchy and ugly.

Then again in some samples it appears as though the k3 holds onto its color balance well at high ISOs, better than the k5, which can take wild magenta or red shifts as things get progressively dark. Who knows, who cares really, they're both plenty good enough for my needs. The *istDS and K10d were not, the high-iso and AF performance were true sources of frustration to me in normal everyday shooting. I think all Pentax cameras since the k5 and including the k30 have probably remedied those issues sufficiently for me.

Oh, and I just can't bring myself to spend more than 1k on an APSC dslr. Sure, the k3 is worth every penny. I'm just too cheap. And crucially: if I'm supposed to pony up a grand or more, that thing better come with a 24x36 sensor. I suspect I'm not alone, and that this is why we absolutely will see a Pentax FF very soon. They have to. People like me are the ones who buy the expensive lenses.

James I hear you. I still have some shots from my *istDS that I print large, and they're not too shabby if I do say so myself. Even some good low-light captures. Some of those made with an A 50mm 1.4 @ f/1.6 etc. No shake reduction, no AF, 6MP, and images I'll cherish for the rest of my life. It was a great small package, I still have my *istDS sitting around. It would be interesting to do a shootout just to see how far we've come.

I was so happy when Pentax moved back to a more compact body for their flagship with the k7.

Looking at it from Ricohs marketing department poitn of view

If there is loads like you who won't pony up $1k for aps-c there's no way on this planet you'll pony up $3k for ff.!

Which leaves people like me who will happily pony up £1k for aps-c and equally happily pony $3k for FF , Unfortunate for Pentax those who needed/wanted FF in my class of consumer are long gone as customers.

I don't believe many of us are counting on a 3000,- FF from Ricoh/Pentax. And there's another thing to consider: many have bought the K5II(S) and that camera might suit for a long time to come as an outstanding Apsc dslr. To spend 1300,- on top of that is something different altogether from spending the expected 2200,- on a new and first FF dslr, with the knowledge that FF is going to become progressively mainstream, whereas Apsc has reached its limits in more than one way

Expected $2.200!!!! what do you base that on ?

I've seen no such claims from any reputable source and imo does not make sense given Pentax current model lines.

There is space for a d800 class camera between the k3 and 645dii but not a d610 class camera

Nope. We're not. If it comes in a penny over 2500 there will be an uproar. Pentax does not have the lens system to command those kind of pro-level prices. And anyone willing to spend that much money on a camera body with shoddy pro-level support and a professional lens lineup with gigantic holes in it should have their head examined for holes of a similar size considering what the competition has available.

That is exactly it. I view APSC as a temporary solution on my path to a FF body for serious photography and a light, compact mirrorless system for everyday, jacket-pocket go-everywhere APSC fun. I'm not a pro and I don't have 10 grand to outfit myself with a FF system. A FF Pentax body absolutely must cost considerably less than 3000 USD or I won't bite, at least not right away.

If no lower-end FF is announced after the high-end one, then I'll go Nikon and spend those bucks on a 24g 1.4, the type of lens Ricoh is not likely to even build in any case and the main reason I'd even want a full frame in the first place. I'm assuming Pentax will simply refresh the FA 24 or do something similar. Actually, come to think of it, even if Pentax do release a FF next year, it will take a decade for them to get the lens lineup in place, assuming they'll even try. I may as well go Nikon now, realistically. But... it kind of pains me to think that. I don't want to. But I know I really should.

There are no such claims of course. My sense that the FF camera will cost somewhere around 2200,- is based on the position of Pentax in the camera market. Why is the 645D the most affordable medium format camera, costing a vast amount less than eg. the Phase One offers? It does not mean that it doesn't offer true MF image quality...

Pentax is all about good IQ at a competitive price, not about the pro's first choice. I don't see that changing soon, in other words: I don't expect Pentax to attempt and take the pro market by storm with a 3000,- + FF dslr. I expect a 24mp K3 style 35mm dslr with first rate build quality (WR) and IQ at a competitive price. What happens after that who knows..

At a "pro level", yes it will take time to build the lens lineup, but when they announce a 24-70, a 70-200 and perhaps soon after some third party offers, they will have the FA ltd's with that and I am sure together with the legacy K mount lenses (M, A and FA), it is a viable start, attractive enough for the serious photographers searching for an upgrade to Apsc, but not for in first instance for pro's. Look at the introduction of the Sony A7(r), not exactly accompanied by an overwhelming lens catalogue at start! I do believe that this is the time to start FF, because Ricoh has the means to build the lens catalogue and carry the investment. They may well be at it already, and it may take less than 10 years...

Neither rich nor talented , but if the equipment matches my need I'll spring for it.

but the wasn't really my point more the observation all those who really wanted FF are now shooting Canon and Nikon FF cameras.

It depends on your opinion on 'pro'

consumer = k500(type) = d610 = $2000

prosumer k3(type) = d800 = $3000

pro 645dii = d4 = $6000

A camera in a league above the d800 @3000-3500 woudl fit you description as that price point is not 'pro' (as your defining it)

Thank you for your thoughtful post, as your posts usually are.

Not that it would make my presence any more relevant around here: I use a K-5 IIs together with various other cameras.

I try not to identify with any tools I use. An opinion by anyone is just an opinion: if the opinion is positive, there are no reasons for me to feel elated, and if is negative, there are no justifications for me to feel attacked. Anyone saying anything about the K-5 IIs is neither praising me nor mocking my choice. After all, it is just a camera and acquiring one doesn't take much. (Actually, I feel like a lame sucker to the Japanese manufacturers.)
 
I think everyone perception varies so what important for one may mean nothing to another.

take me

my K5 was on 75,000+ shutter actuation over 3 years old.

It has been a great camera flash a disappointment, sensor a revelation, performance functional

the k3(in relation to k5) promises , 2 year warranty , flash a revelation, sensor OK, performance above adequate

to me that is worth $700 upgrade cost for 3-4 years of worry free shooting.

If you look at Donald , k7 shooter not impressed by K5 how can he possibly be endowed by the k3?

I refused to give the k7 house room when compared to the k20d so cannot comprehend his love of the camera but it doesn't really matter what I think for him it does the job better than anything he sees newer.

if you look at k5ii owners they already have 60% of what the k3 offers so may not see the same value proposition, though I would say if they went k5 -> k5ii (imo 20-30% improvement) then the k3 has to be great value offering a more convincing performance jump
