This is why I refuse to purchase any more Pentax bodies. The company should have admitted the defect early on and recalled them all...still should. Someone needs to file a class action lawsuit against the manufacturer for deceptive business practices, just like Volkswagen.

The ad hominem attacks appearing in this forum are neither appreciated or productive. As it was, shortly after the release and purchase of the K-3, Pentax denied there was a problem (told me they hadn't heard of it) and had no "cure". After all, why would they have a cure for something they claimed they didn't believe existed?

I posted my opinion of the product and didn't expect a hash of recriminations for it. What I DID expect (but didn't get) was an answer to my question about whether there had been a recall by Pentax for a range of serial #'s in the K-3 and if this recall was independent of the "warranty" period.

You can't fix stupid. It's stupid to buy a known problem put out by Pentax: Defective Camera bodies with machine gun mirror chatter. It tears up the innards and baffles. There are other problems associated with said bodies too like failure to record a picture on one of the two SD cards, etc. I read on one post Pentax had recalled a range of serial #'s associated with this problem. Can someone tell me if that's true? If so, does that recall remain valid even if the 1 year warranty period has lapsed? Is it for the Pentax K-3? If so, I'd like to return mine and have it 'fixed' if that means more than just a firmware upgrade. I will not ever purchase another Pentax if these kinds of manufacturing defects persist and the company fails to resolve them with its customers.

jhmos, I believe there's a relatively simple explanation for the manufacturing defect which has troubled me as well. If I'm correct, then so are they: There's no real 'fix' for the problem because it is a design flaw deep within the circuitry of the camera.

Pentax/Ricoh modified this camera (K3) extensively during the design phase, adding many new wonderful features. What they did NOT do was adequately compensate for the additional current draw and resulting voltage drop to the circuit board. There is a window or voltage range in which the electronic components will behave normally. Outside that range, results will be unpredictable/frustrating. Well designed electronic devices have a voltage regulator that more or less guarantees the supplied voltage remains within the desired window/range. In this instance, that window was either too narrow or improperly set to allow for variables such as disparate batteries (rechargeable vs. zinc battery voltages, temperature, etc.). The runaway mirror problem damages the camera by tearing up the baffle while rapidly flopping. Crumbs from the damage will land on the K3 sensor, further degrading its performance. This is a deep seated manufacturing flaw for which the company has never fully accepted/acknowledged responsibility. It's erratic because the conditions leading to it are variable. The camera also (for the same reason and as erratically) sometimes misses a shot or does not record video/pics to one of the two memory cards. The camera is, therefore, unreliable. Ricoh should remedy this for ALL purchasers of the K3 regardless of their reticence to send off their gear/camera to some distant repair shop only to receive a SOP, excuses, or mollification. Ricoh sold EVERYONE who purchased a K3 a lemon, regardless of whether they actually ran into one of the set of conditions which cause the camera to fail or not. Not everyone who purchased a Corvair died. That doesn't mean the car was safe. Ricoh sold a lawn mower that cuts grass MOST of the time. :(

Purchasers might notice battery life on the K3 is considerably shorter than the K5. The reason (and consistent with the above reasoning) is simple enough: Its circuitry draws/requires MORE power!

Bigger offers more, negligible or not depending on sensor size, but the trade-off between expense and gear bulk/weight was never mentioned--even if $ was no object. The truth is there are fewer lenses available for, say, the Pentax line of cameras if a FF existed. Then there's the matter of packing it around. Would your back/neck stand up to it? For a street/news photographer, the APS-C format has a lot to offer and won't cause disk dislocation. It's been said the BEST camera is the one you have with you. How often would you have an 8x10 with you?...or even an FF? APS-C is about as big as you want to go if you want to remain optimally mobile. FF lenses are bigger, heavier, more expensive. Bigger sensors take a LOT more computer processing for editing and digital storage space. Maybe the landscape photographer can justly lust after an 8x10 camera, but for us mere mortals where human faces are our canvas...not so much.

More than 1 person has purchased 2 or more K3's and found the mirror flap problem in both. Ricoh is not trying to isolate the problem. They're stone walling it. Anyone plagued with this problem deserves a NEW unit because the manufacturing defect existed ab initio. They won't get it, of course, from Ricoh. All hi-tech manufactured electronic goods will experience a % of defects. Those can be corrected. What cannot be corrected is a company without the commitment to its customers they deserve. That's a character problem not easily resolved.

One observer claims the likelihood of the mirror flutter/stutter problem arising is tiny/trivial based on the calculation of the total number of occurrences posted HERE divided by the total number of K3's manufactured. This is a flawed analysis because such tiny numbers of Pentax owners (let alone K3 owners) post here...or even READ here...at all. The more relevant analysis should be what are the odds, if the defect is truly 'rare' a person (such as Rabbit) would get TWO defective K3's in a row? But wait!--Rabbit claims there are at least 2 others who have ALSO gotten 2 defective K3's. Rabbit's analysis is the more accurate. The odds of having 3 people getting 2 new K3's with the same serious manufacturing defect are incredibly infinitesimal UNLESS the (false) presumption the defect is rare is wrong. If the defect is, however, common, then the odds of a user receiving 2 K3 lemons is substantially higher. Again, few Pentax owners even read this forum. So the odds of at least 3 of them getting double whammied by the K3 flaw is very interesting/curious unless you are into denial. Pentax/Ricoh, of course, has an incentive to be into denial.

The seriousness of the problem depends somewhat on your tolerance: If you're simply a casual shooter in a casual venue taking hobbyist shots and don't mind the mirror baffles raining debris on your sensor from the beating it takes, or the display screen freezing, or the memory card in slot #1 not being written to, then throw the dice. But don't be under the illusion this flaw is minuscule--it's not. Rather, it's very sporadic and unpredictable. The fact that it happens at all indicates a design flaw. No camera should experience mirror flutter/stutter. A simple FOR/WHILE loop with a limit (say of 3) within a second, or a similar logical limiter would have made the problem moot. If you're a SERIOUS photographer (weddings, courtroom photojournalism, stage performance, wildlife, street, investigative) then the K3 is NOT for you for obvious reasons. The K3 could end up causing you to be removed from the venue and becoming persona non grata. Worse, it could make ALL photographers unwelcome. It's like having a dog that piddle's on your host's floor.

Ricoh's reticence to be more transparent about the flaw may mean the company itself cannot be trusted to be genuine with its customers. That's a problem too--perhaps a bigger one than the K3 has. What are the odds? Do you feel lucky?

Not only (as I've previously posted here) has my K3 Silver limited edition exhibited the notorious runaway mirror stutter/flutter malfunction from very shortly after receiving it in December by preordering from B&H (neither the retailer nor Pentax/Ricoh has been helpful), but the mirror has damaged the baffles, raining debris on the sensor which I can't get rid of through the cleaning cycle. The unit has problems with white balance (cycling from one extreme to the other) in video. The unit occasionally refuses to write to the SD card in slot #1. On a recent trip to Portland's rose garden, the display screen froze until the battery was removed. There is a deep manufacturing flaw in the K3 which Pentax refuses to discuss/acknowledge, still claiming they haven't heard of it. CRIS does not say they've never heard of it. Pentax owes each purchaser of this defective merchandise a NEW uncompromised unit. They refuse to do this. It's likely Pentax/Ricoh will have to face a lawsuit before they get off the dime. They're engaging in a beached whale strategy, leaving their customers to twist slowly in the wind. The K3 is a lemon because, while it has incredible potential, the manufacturer will not own up to the problems exposed. Those who haven't experienced the problem have been lucky. There's no guarantee they won't be visited by it in the future. The flaw is more pernicious than simply firmware, else Ricoh would announce a fix they are now applying to all units produced after a certain serial # sequence. They've soiled their reputation and are hoping nobody will notice the stench.

I'd love to hear from a Pentax/Ricoh rep willing to take accountability for a defective product and make it right. They're either unable or unwilling to do so. It's a typical David and Goliath business relationship where the customer gets the dirty end of the stick. Their 1-year warranty only offers a band-aid, if that. The electro-mechanical apparatus and circuit board are defective. For what it's worth, Pentax/Ricoh cannot even say what the problem is, and their talk of 'reducing' the likelihood of the problem repeating itself is tantamount to an admission of failure. If you own Pentax/Ricoh stock--SELL! If you own the K3, sell it too before the bottom drops out.

Yes, me! It's pretty bad and happens more often than not on a day's shoot. (#2574437) A firmware fix wouldn't satisfy me. That's because the mirror mechanism has already torn up the baffles to the point of depositing debris on the sensor, affecting the IQ. Additionally, the unit does not write reliably to the SD memory card in slot #1. It's a class 10 Sandisk 32Gb card. They've been flawless and I own about a dozen or more of them.

What I'd really like is a new camera without the defects. I *NEVER* received one. It misbehaved almost immediately upon receiving it last December. But, because B&H "hadn't heard of it" (even now, so they say) it would have simply been returned to me as is if I'd sent it in within the 30-day retailers warranty. I feel Pentax/Ricoh owes me a NEW uncompromised K3. When I called customer service, the guy said he hadn't heard of the problem (I referenced this forum) and seemed indifferent to my feeling of having been ripped off. Furthermore, Pentax/Ricoh is STILL being sketchy by refusing to specify where, exactly, the problem lies. Nor will they admit how common the issue is. They continue to claim it's minuscule. I strongly doubt that.

I have never used time lapse on my K3, yet I'm plagued with the mirror stutter/flutter problem which is tearing up the guts of the unit. My SD memory card periodically fails to be written to in slot #1 as well. I like the K3. I paid for one. I'd like one that functions properly and reliabily.

Chris Mak, silence? What's with that? Is that some Japanese tradition? How about transparency and owning up to a problem or manufacturing defect? Nah, that'd be too candid and at odds with the kind of character we saw surrounding the Fukushima nuclear disaster.
The K3 has a problem. Those who purchased it are at risk of being affected by it. Pentax/Ricoh should indemnify them by offering a non-defective unit or their $ back ASAP.

Amy, I'm going to try to return my K3 to get one that works properly or my purchase price back. Without your efforts, I doubt this would be possible. It might not be in any event.

Rupert, many have found debris on their K3 sensor after the mirror stutter/flutter. That seems like it's tearing up the internals. It can NOT be good for the K3's longevity as it isn't designed to be a machine gun.

I've been following DRabbit's thread about the defective K3's for a while but haven't commented because the registration process was daunting for me. I *did* post on the comments in the article she (Amy) posted on Steve Huff's well read photo blog. I've been having the same problem as Amy, perhaps more so. I haven't shot nearly as many shutter actuation pictures as she has. (between 4k to 5k) Yet the mirror flutter problem has bit me more times than not when I go out for a day's shoot. Amy has been very helpful in emphasizing this manufacturer's defect. It's MORE than annoying. It is destroying the K3...mine! I have debris on the sensor as a result, though I didn't connect it to the mirror stutter until I read of others reporting similar problems after experiencing the issue. And, Amy mentioned her memory card (it's a 2-slot unit) getting hosed. Bingo! Now that I think of it, mine also hosed the card in slot #1. Fortunately, I'd set up the parameters to where the card in slot #2 saved them when the camera hosed the one in slot #1. The card works fine in all my other digital cameras, including Pentax bodies.

At first, after reading so many reports of the problem, I thought the issue might be caused by a mechanical problem with the 'mirror' (prism, actually), but the SD card in slot #1 belies that hunch. It is almost certainly an electrical problem deep in the circuitry, perhaps one of the CPU's. This will be no easy fix for Ricoh and problem goes back to a design flaw dating to the K5. It sounds very much, in computer geek language, like a 'race' condition. If so, Ricoh won't be able to guarantee a fix by merely replacing a consumer's unit with another one because they likely ALL have the potential under uncertain conditions to fail in this manner including corrupting the SD memory card. Why not the SD card in slot #2? I dunno. But this problem sounds like a BIG one whether all purchasers have experienced it or not. To guarantee it won't happen again to its customers, Ricoh may have to replace the circuit board and CPU in ALL of it's K3 line or give customers their purchase price back. Machine gun chattering mirrors/prisms in a camera body are tearing apart the internals as they are NOT designed for such abuse. The failed memory card (which I also experienced in my K3, but not ever in any other Pentax camera body I own--7) seems to suggest it is NOT 'merely' a mechanical actuation problem, but electrical/logical as that's what writing image files on the SD memory card is about. I'm going to guess it's Pentax's new PRIME III engine. I'm also going to guess that the circuitry is inadequately grounded, which could introduce transient unintended current flows in the circuitry triggering some of the transistor gates into misbehaving. This is all speculation, of course. Ricoh's problem is the 'fix' is going to be expensive...a total recall or return of purchase price. They may be hoping that so long as they don't acknowledge the seriousness of the design/manufacturing flaw, with time consumers will forget and they won't have to bite the bullet. It may be only a class action law suit will shake loose responsible corporate behavior.

Customer: "I have a problem with this K3 and mirror flutter/stutter. It's still under the manufactuer's 'warranty'."
Ricoh: "Yeah? Well you can't prove it, and we can't duplicate the problem."
Customer: "But, all these other consumers on the internet (including Amy) have posted complaints about the same thing!"
Ricoh: "We don't operate/manage our company based on internet posts/blogs. Sorry, we can't help you."

I purchased my K3 in the U.S. from B&H. I preordered the K3 Silver unlimited edition. I noticed the problem within the 1st week after I actually received it. But, I've gone through this loop before. Sure, the retailer says its guaranteed for 30 days through them, 1 year through Pentax after that. But, if they can't duplicate the problem (it is an erratic unpredictable one), they'll simply return the unit to the purchaser. You'll have spent two or three months waiting for exactly the same unit in exactly the same condition it was in when you asked for it to be fixed. Under these conditions, the retailer's/manufacturer's/purchased warranty MEAN NOTHING! It's the perfect scam--defective/shoddy electronics merchandise with no remedy for the consumer multiplied by how many sold K3's? Yeah, your camera may not experience a catastrophic failure...at least right away. Would you accept a newly purchased new car under the same conditions?

Consider: Nearly 100 reported incidents of this defect in just over a month when not even 1% of consumers who get bitten by it are going to post, if that. Amy gets two defective K3's in a row. Steve Huff's unit received for review locked up before he could even evaluate it, thus no review. MY K3 sucks too--mirror flutter/stutter the majority of the time it's used for a day, debris falling on the sensor, failure to write to the SD memory card in slot #1. The K3 is a ticking time bomb and a lemon. The K5-iis is very good without these problems. It also has a different circuitry, processing engine, CPU, and sensor. I truly want what a paid for: A reliable properly functioning K3!
