-How would you rate the look overall?
Underwhelming.
-Does the 40mm fit the camera well?
I find the question meaningless. The lens is quite flush, but given the camera's dull appearance, it makes no difference.
-Are you planning on buying one based on what you've read about it in the official announcement?
Under no circumstances. My K5s are much better, and better looking. The only area where the K01 provides an improvement is unimportant to me (video).
-In buying a camera, how important is the look compared to the features? Very important, somewhat important, or unimportant?
This question needs to be defined better. Are you talking about people you are trying to entice into the Pentax brand, or existing users? An exceptionally attractive piece of design (which unfortunately the K01 is not) will sway the uncommitted more than features will. People buy emotionally and then justify logically. This is at the heart of Apple's success. Anyone who thinks that people make a reasoned and cogent series of rational judgments before buying something are delusional. Any insightful advertising agency will tell you that human psychology is ruled by a primitive and irrational part of the brain. Apple products produce (according to brain scans) the same sort of response that deeply religious people have to their religious iconography. Apple understand this, and play the mystique card for all it is worth. They cement their relationship with their customers by, on the whole, producing exceptional equipment. That isn't what entices people in, however. Design appearance and mystique is what grabs the uncommitted. Religious fervour is what keeps them.
-How do you think people who've never heard of Pentax would react to this camera?
Mild indifference. If they have never heard of Pentax, then the odds are they have little interest in photography outside of a pocket sized point and shoot zoom camera. If there is sufficient circus ballyhoo they might raise a weary eye and wonder what all the fuss is about. People who know nothing about photography aren't going to be influenced by a non-DSLR camera simply by virtue of it having a technical spec that is irrelevant to them (i.e. interchangeable lenses). If the K01 were a stylistic triumph, then the ability to use a blizzard of interchangeable lenses on it would enhance the way in which it is perceived. As it is far from a stylistic triumph, few people will care. It isn't sufficiently smaller than a K5 without the battery grip to matter, and it is bigger than a pocket-sized point and shoot camera. The unfortunate outcome is that the K01 is neither one thing nor the other. It reminds me a lot of the Mac Cube (who remembers that?) in the way that the Cube was neither laptop nor desktop, but managed to combine the disadvantages of both and sink without trace.

Should I get an LX?

The FB/FC system finder is darker in use than the standard finders (partly due to all that glass), but immensely versatile. It will rotate to allow use as if it were a waist-level finder (useful if you ever shoot from very low angles). It was my standard finder when I used LXs. If you wear glasses, the high-eye point that the FC1 action eyepiece gives saves you from smacking them against the finder. Obviously if elegant lines are what you are seeking, the FB/FC combination won't give you that as it protrudes some distance behind the film back.

Note that the FA2 finder lacks the judas window of the FA1, so you will not see the aperture selected in the viewfinder.

Should I get an LX?

I used LXs for eighteen years. The top and bottom plate metal is not as thick as the equivalent Nikon and Canon models, but Pentax's genius in producing a design that combines elegance with practicality and sophistication is evident in every aspect of this camera. It also had better sealing than others in its class (the only obvious omission being the lens mount)..

When LX was given a thorough field test for the British Journal of Photography (when it was a new camera), the magazine's editor found it hard to fault, commenting specifically that it was nice to find a camera that appeared to have been built up to a price, and not down to one. He also described LX as "a breath of fresh air."

You will benefit from having the grip B if you can get one. My experience of the motor drive is that it was metal, but the LX NiCd power pack was a heavy-duty plastic. The motor drive can also accept the battery pack M from an MX.

Using the histogram on K5
Posted By Delgado

I need to make a correction to my previous post. Depending on memory is always a mistake.

The K5's histogram represents what would be produced if you were shooting in jpeg at the existing camera settings. Jeff Schewe and Bruce Fraser's work on Camera Raw comments that camera vendors tend to apply a strong tone curve to the default Raw to jpeg conversion (possibly in an effort to mimic the appearance of transparency film). The on-camera histogram is useful as a rough exposure guide, but not much else. Overexposure warnings (say where the histogram shows clipping to the right) appear to be quite conservative. Raw shooting will give more scope than the on-camera histogram suggests. For an accurate histogram, you will need to view your files in post-production - in for example, Camera RAW or Lightroom.

RAW shooters should also keep in mind that the histogram is based on the embedded jpeg in any RAW file, and is not an entirely accurate representation of the way that a RAW file will deliver an image. Often when a histogram shows blown highlights, the RAW file will still deliver a good image. If you shoot RAW, the histogram needs to be interpreted less literally.

Just because a picture on screen looks sharper does not mean that it is. Many years ago (pre digital) one of the mistakes that was easy to make with simple "eyeball" assessments, was that lenses that could deliver greater subtlety of tone were sometimes judged to be less sharp than more contrasty lenses. The additional fine gradation of tones made the image appear less sharp than the contrasty image.

You do not say if you shot in RAW or jpeg. My experience of the K5 sensor is that in RAW it is far superior in terms of subtlety to anything I have used before - especially at low ISO. I don't do jpegs for origination, so I can't comment on jpeg output. If you have shot in jpeg it is worth keeping in mind that similar settings on both cameras do not necessarily translate into the same processing of the image. Each camera will handle the processing differently and very likely deliver different results. DSLRs today are like high performance racing cars. Each new model will need tweaking of its settings in a way that suits the needs of the sensor. You can't necessarily just carry over the same settings and expect the same results.

Pentax Q small-sensor mirrorless camera announced and previewed

If I have read and understood this correctly, the standout feature is a sensor using backside illumination. Sony have been doing a lot of work on this kind of sensor. If that is the case, it can make use of incident light (in the same way that film does) rather, than only light that is arriving perpendicular to the sensor. This would account for its alleged superior performance under low light.

Wacky color balance in sequence shooting
Posted By Delgado

Views: 1,933
The only comment I can add is that my experience with two K5s is that the K5 white balance is much more aggressive than it was with a K7. I always shoot in RAW. I have noticed that the slightest change in the subject can produce a change in white balance. I am assuming you had it set to Auto white balance, as that is the only time I have experienced the problem. Setting it to "Daylight" or any other fixed setting eliminated the problem for me.

LX shutter not working when winder is turned on?
Posted By Delgado
Replies: 9
Views: 2,669
For whatever this comment is worth, I have just looked at an LX I have with a Motor Drive and a dead NiCad battery pack. When it is set to C or S (or even R), the shutter will not release even within the mechanical shutter speed range (the shutter speeds that don't need battery power). The shutter release only depresses about half-way before hitting something solid. When I switch it off at the rear of the Motor Drive, the shutter releases properly. The problem you have described with your winder suggests to me that there is something wrong with it. The LX appears to stop working if it is not sensing power from a connected external drive. If your winder power cells are good and inserted with the correct polarity, then it implies that the power is not being fed through in a way that the camera can read, or in a way that can power the motor. I have checked the top plate of the motor drive (removed from the camera) when the unit is switched to C or S, and nothing raises from it to provide an additional connection. Any communication must be via the normal electrical contacts. Switching to C or S appears to allow the body to divert some of its own power into the drive to establish whether or not power is available. I checked this by removing the button cells from the LX body, and then re-connecting it to the Motor Drive again. Without any power to the body, the LX shutter was OK throughout its mechanical speed range even with the dead NiCad.

The only quick way to verify you have a faulty drive would be to test it on another LX body, which I'm assuming isn't practical for you. Have you seen any indication from the winder that it is powered at all? I am not familliar with the winder layout, but the Motor Drive had a red light that indicated when power was available if switched to C or S. Also, the rewind lever triggered the motor even when the unit was removed from a body. If you are not seeing any life from the winder at all, I would guess it is faulty.

Sorry I can't be of more help.

Exactly - with USER settings you have to save them explicitly - they are not retained by default. If no save is made, the camera just reverts to stored settings once the power is shut off. Another small lesson learned.

Because I have 5 different configurations of settings programmed in for USER mode, I habitually leave K5s set to USER (all of the set-ups I have programmed in are variations on Manual anyway, so I rarely need to switch to M).

I have found that if you try to amend menu settings with the camera set to USER, it does not retain changes. Setting it to M solved the problem. The AF light setting has been retained now.

Thanks to everyone who checked.

I have (generally) the DA* 16-50 2.8 on one and the DA* 200 2.8 on the other. Both have a battery grip. AF mode is set to AF-C, and AF sensor is set to multi - AF point.

Very odd in that it is affecting both bodies.

K5 AF assist light will not switch off

A few days ago I needed to switch off the AF assist light in both of my K5s in order to stop distracting people at an event I was covering. I switched it off in the menu of both cameras. The setting was only retained temporarily. After a while (probably after each body was set to auto-switch off) the green AF llight came on again when I touched the shutter release to wake the cameras up (and no, I'm not confusing it with the top plate window light). I have tested both bodies, and this happens consistently if I change the setting in menus, and then switch the body off. When I switch on again, AF assist lamp is on again and the menu setting is back to the default of "on." The setting is in Custom Function panel 3, item 17. Ihave changed the setting from "1" to "2", but after a switch-off, the setting reverts to "1".

Both bodies are using firmware 1.03.

Is this something that anyone else can verify? It isn't a major problem, just a nuisance at present.

I've updated to FW 1.03. It still makes no difference, even though rotation is enabled in the Menus. Overall it doesn't matter to me - I just find it puzzling that it has been documented as a problem for some time without any acknowledgement. The problems that matter are being addressed (for the most part), so something gimmicky not working hardly seems worth me getting upset about.

Is k-5 a failure?
Posted By Delgado

I run two K5s. It is by some margin the best DSLR I have ever used. Any piece of high technology is going to be flawed (for a good example see all of the old reports about the recall of the flagship Canon 1D MkIII). This does not make it a bad product. If we as customers were willing to allow manufacturers a proper lead time in developing new products, we would see fewer problems. As we do not allow this (in fact we penalise any manufacturer who does not dash to market), we need to accept that early releases of these products will carry some risk of problems. The solution - if you can't agree to that - is to wait until six months after release for the flaws to have been identified and fixed. When I used LXs my camera bodies were good for 18 years service while only the film technology changed. Today the front-line life cycle of my DSLRs is about fifteen to sixteen months. The price we pay for all of that high-tech development of a product pitched at a price affordable to many people, is that some flaws will slip through.

A couple of years ago a writer in the Photographic industry made some predictions for the year ahead, one of which was that a Pentax would be the first DSLR to incorporate Stanford University's Refocus technology. The prediction was somewhat off given that a couple of years have passed without Pentax adopting it. That said, the technology is still under development by Refocus Imaging Inc, and that seems more of a revolution in the true sense of the word to me than any amount of GPS gimmicks.

This is not a prediction (I have no inside information). Just an observation in relation to the word "revolution."

K5 metering and color temperature woes
Posted By Delgado

For whatever this comment may be worth at such a late stage in the posts, I have found K5s to be a bit over-sensitive to colour temperature shifts simply through slight change of camera position. This is noticable in comparison with the K7.

Generally my solution is to either set a custom white balance using a Whibal (white balance reference card) or, more simply, include a picture of the Whibal one or more shots and use that as a white balance reference when I import the files into Adobe Camera Raw. The custom white balance would probably suit jpeg shooters better. I always use DNG.

The sensor stain problem with some K5s puts Pentax in a far from exclusive club. While it is right to highlight what Pentax needs to do better, keep in mind that one of the big players with far more resources in this division, had a bigger humiliation (given that its flagship model cost as much as an armful of K5s). See quote from DPReview that follows:

"Canon UK has apparently informed dealers that it has temporarily stopped shipments of its EOS-1D Mark III and is asking that unsold units be returned pending an official announcement due over the next few days. The state of play seems to be that Canon will repair affected cameras but is not offering refunds or exchanging for alternative models."

These problems are a symptom of the insanely short life spans of current products, and the pressure from consumers to get the next generation out so quickly. It will keep happening until manufacturers believe they won't be penalised in the market for slowing the pace of development and implementation. Early adopters of new models need to be aware of the risks and accept them. If that isn't acceptable, the solution is to wait a few months until the bugs have been found.

I used LXs for eighteen years (admittedly with the film technology changing throughout) without feeling underprivileged. Today I find my current DSLRs have a front-line working life of less than a year and a half. I have chosen to accept the benefits of the technological improvements with each new generation of models, and also accept the price that occasionally this will go off in my face. I have to say that in every respect other than sensor stains on one of the two bodies I bought, The K5 has been phenomenal.
