Corrupt Images: Any last suggestions before I send the K1 in for repairs?

If this is showing up on your camera when you review an image, you can immediately rule out everything else downstream (card reader, computer, etc.). It would have to be either your camera or the SD card and since you have used multiple SD cards, it would most likely be camera related.

If this doesn't show up until you look at your images outside your camera, then it can be something else and software can most certainly be suspect as BigMackCam suggested.

Have you formatted each SD card in your camera prior to use? That would be the only thing which could affect SD card performance across different SD cards. Just out of curiosity, how large and what type of SD cards are you using? What version of Windows are you running?

Any suggestions about what this is on my lens?

Don't be afraid to dampen the q-tip with a bit of lens cleaner - some stains can be stubborn and simple rubbing may not budge them (if you rub too hard it can be detrimental and lens fluid will act as a bit of a lubricant). If there is any abrasiveness to whatever is on your lens, that could damage the coating - keep it soft and gentle. A better choice would be some lens tissue if you have access to it.

K1 self-timer AF

A problem with AF and a self timer is that unless you know exactly where to stand (in the AF bracket) the AF could focus on something else and you would be out of focus. I think this is one reason it wasn't included as a feature of the K-1. The best advice is what kiwi_jono said. You could have a stand-in take your place while you are focusing just to have a focus reference.

K-1 II In Camera HDR
Posted By Bob 256

Actually, those images look almost identical to me. Here's a possible reason.

Consider you have two cards and send DNGs to one and JPEGs to the other. When you take an HDR shot, the resulting DNG has three exposures encoded as one file and is recorded on the DNG card. At the same time, that DNG information is processed by the camera according to the HDR mode you have set (HRD 1, HDR 2....etc), and the single image HDR image goes to the JPEG card as a JPEG. You also see the processed image on the LCD screen.

If you were to drop the DNG card into a software program which doesn't recognize the encoded HDR file, it may just default to one of the three images (which wouldn't be HDR). It would do the same for all of the HDR camera modes (in fact all of the DNGs are identical regardless of the HDR camera mode).

If you look at the JPEG card, you would see the different HDR modes and they would be markedly different from each other. However, if you want to change the HDR processing, you can't since it was done in the camera and you have a finished product.

I use two cards and simultaneously capture DNG and JPEG files for each HDR. Sometimes, I end up using the JPEG as is since it can be a reasonable HDR photo, but most often, I use RAWTherapee to separate the DNG into its three exposures (16 bit tifs) and then drop those into Photomatix which provides a multitude of HDR options for processing, and that spits out the final HDR image.

You're probably trying to view a DNG on software which doesn't know the DNG is HDR and doesn't use the three encoded files properly. You have two choices - use the JPEG file which the camera has processed to HDR or do something like I described to get a true HDR output (the right software should be able to do it without involving Photomatix). Without knowing the capabilities of the software you're using, I can't surmise exactly what's happening but chances are, you aren't seeing the HDR result.

Do as Adam suggested and write a series of JPEGs (using the different HDR modes) to a card and look at them in your software viewer. They should show HDR and be considerably different from one another. For DNGs, you may have to resort to different software or determine how to get your software to recognize the encoded HDR images in a single DNG file.

Which flash is better for my K-1
Posted By Bob 256

Check out the AF201. It might be too small for what you want, but for general use, it replaces a flip-up flash, is very compact, and has four modes (auto and manual). There are reviews of it here: PENTAX AF 201FG reviews - Pentax Camera Accessory Review Database

I have the AF540 and the AF201 and find myself using the latter more often because of its size and I can drop it in a pocket when not using it if I don't want it on the camera. It has a flip-out diffuser for use with wide lenses and takes 2 AAA cells which deliver pretty good lifetimes considering.

Looking for a liquid film dev. with results like D-76?
Posted By Bob 256
Replies: 77

You can formulate D-76 yourself if you have the proper chemicals and make up any quantity by scaling the basic formula. The downside is you still have to work with powdered components (some of which pose some risk), and you need a scale for accurate measurement. You can also mix concentrated batches to have a liquid on hand which will keep longer than the diluted developer (again you can use measured amounts of the concentrate to get the volume of developer you're after).

Poll: Pentax K-1F idea
Posted By Bob 256
Replies: 37
Views: 1,210
I think the Pentax PZ-1 was close to the K-1 in many of its features (at least those film allowed) like instant switching from P mode to Av or Tv mode with the use of adjustment dials, and control of lens aperture with a dial, but digital has much to offer and one of these days, film is going to be hard to find (many of the former emulsions that gained fame through the years are long gone).

Digital has matured and nowadays, sensors have more sensitivity than film, show no reciprocity effect, and can have their effective ISO adjusted over a wide range electronically to accommodate shooting needs. Granted there are some niche advantages to film, but a new film camera just won't make the grade in terms of profitability so it is very unlikely that anything like a "K-1 film" camera will appear.

Keep in mind that I am talking about 35mm, and this doesn't mean I don't shoot film anymore or want film to go away, but in terms of seeing a new "hi tech" 35mm film camera, the cards just aren't falling into place (and most likely won't).

Thanks jbondo. I will check that out as well. Right now, for the limited amount of editing I intend to do, the video editor suggested by bigdavephoto is appealing. I think I'll give that a spin first and see what it looks like. I'm an Adobe Premiere user from some time back (SD 720x480 days) so I'm also looking at Adobe Premiere Elements, but again, due to the simple requirements of this project and the fact that it's a one time deal (right now anyway), I think I'll go cheap.

Audio-wise, a lapel mic with the Sennheiser transmitter/portable-receiver pair looks to be very workable with the K-1. I need to build a mono to stereo adapter cable so I can feed the mono audio to both K-1 stereo inputs with just a simple cable mod, and I should be in good shape on that end. I understand the K-1 uses a 48kHz sampling rate, so for voice, that should be more than adequate.

I'll let everyone know how I finally come out.

Thanks again for all the input - any other suggestions are appreciated.

Thanks for that referral bigdavephoto - I'll check it out. I have discovered that I can run a single clip through AVStoDVD and it will put in into a DVD writable format (VIDEO_TS folder structure with menu) but I don't have a solution for joining multiple clips right out of the K-1. I can also go with a Blu-Ray solution since I have a BD writer. In either case, I would like to keep as much picture quality (HD) as possible.

Ok. At this point I have secured a Sennheiser G3 transmitter/receiver pair with a lapel mic (that package came in at under $200Us with some qualifications I won't get into here). My K-1 audio output was too wimpy to drive my Sony headphones (used for monitoring and playback reviewing) so I also have a small headphone amplifier coming to address that issue.

I think that covers the audio needs but can one of you folks with K-1 experience help me with the file handling end of my question? Once I have the video/audio file on my SD card, what do I need to edit several clips together into one and come up with an mp4 file?

Appreciate the advice.

Thank's folks for the replies. I don't have an assistant or a place to rent Sennheiser equipment, so have to wing it. I was looking into a MOVO WMIC 80 but they have poor reviews????

This is a one time (hope) request so I don't want to invest that much though a $200 MOVO might fit if I could use it again in the future. I'm pretty aware of levels and issues like clothing noise and can handle those if they cause problems. I really don't want to go the separate audio route and the recombining it requires downstream in post - would like a finished product once clips are edited and transferred to a disc.

My main issues right now are a recommendation for a low cost wireless and file handling from the K-1. Thanks again.

I have a case in which I need forum help from some experienced K-1 video users.

I’ve run into a need to shoot an interview video using my K-1 and although I’ve done video before, I’ve never used the K-1, defaulting to a camcorder for that. This time, I need more professional audio so would like to use a wireless lavalier mic and a receiver plugged into the K-1 (split to both channels for mono sound - my camcorder doesn’t provide for wired audio inputs). I also desire 16:9 HD video though no need for UHD. No fancy zooms or focus tracking is anticipated.

Two questions (more like three): 1) what’s a good low cost wireless lav microphone set that can be used with the K-1? 2) What is a reasonable editing software (low cost or freeware) that can be used to edit separate cuts (once transferred from SD card to hard-drive) into a singular presentation and 3) output that to a structure which can be burned to a DVD and played on any DVD player? If I can get an mp4 file, I have software than can add a menu and output a TS_VIDEO folder.

My reasons for keeping it simple are that it won’t happen that often although I would like to produce a reasonably high video/audio quality end product which will be used for a big screen (literally - not big as in major motion picture) presentation:)

Thanks.

3d printed Mode Dial for k-01

Good idea but the mode markings are a little harder to come by unless an engraver is available. A good 3D print will have those as shown, and is a great way to fab a replacement if the 3D printer facilities or equipment is available. Not quite as good as an aluminum knob with engraved markings, but a pretty good replacement.

Welcome and happy K-1 to you.

Just like fine wines, use and understanding of the K-1 will greatly improve with time. It has a steep learning curve but once you start to master its functions one-by-one, it gets much easier to use. You'll find you have your favorite modes to use and it can make the most of good lenses to produce outstanding images. Take your time and read about it here in the archives when you can - the K-1 thread has a lot of good Q&A to absorb.

I've used the Wi-Fi commander software that was talked about here with my laptop running Windows 7 Pro and it works great. Speed is signal strength dependent but it will download existing files well and it also allows control over K-1 camera functions wirelessly.

If you like it, don't forget to leave a "tip" for the creator (I have no connection with that person but I believe in fairness for free software creators and believe it's the only way we will see improvements or newer versions of good applications).

InfaRed with a K-7

UV/IR cut (blocking) filters have improved (also, less expensive cameras omitted a good one because of cost), so much less IR gets through with the newer or better digital cameras. You still may be able to shoot IR, but it will require a long exposure with a faster lens. As UncleVanya stated, the best solution is to have the filter removed though that introduces issues with regular shooting and usually requires an UV/IR cut filter over the lens for normal photography (these are available on ebay and elsewhere). However, if you want a camera for shooting just IR (and UV), then get the filter removed. I had my K-01 converted to full spectrum and it works great. You won't be able to use your viewfinder for focusing so liveview (with a VF camera) or mirrorless (liveview all the time) is the route to go as with my K-01 (which is mirrorless). Removing the filter can be a little touchy, so it is best done by someone with experience (there are some threads here about doing it yourself). I used services provided by Isaac Szabo and was very satisfied.

Sensor Dust or No Sensor Dust?
Posted By Bob 256
Replies: 16
Views: 971
Actually, when you remove the lens, you're looking at the UV/IR cutoff filter which sits in front of the sensor. If a camera is designed properly, dust won't have a path to the sensor itself but can settle on the filter. Most often, I've used compressed air to remove dust motes, but in the year I've had my K-1, I've only had to do this a couple of times (and that was the only treatment needed - no swabbing or contact cleaning). As Larrymc indicated removing the lens is done often enough that cleaning the cutoff filter shouldn't be that worrisome - only if you get some really bad gunk in there.

You'll have to give it a re-visit - they were having a grand opening of the new section a couple of days after I was there but all of the new renovated center was open and has really improved the arch with more room for exhibits, etc..

If you go with the K-1, try some Pentax alternatives on the battery. I got 4 Watson batteries and as far as I can tell, they provide the same capacity and performance as the Pentex OEM battery at about $20US. The same charger can be used although Watson batteries are a little on the loose side in that charger so you have to make sure they are making contact when charging.

Two per camera has worked well for me, but if you're a really intense shooter, you might go for more - recharge time is about 5 hours.

Welcome Bart. I was just in St. Louis a couple of weeks back and checked out your Arch - fantastic. If you're in St. Louis...............................

I've had my K-1 for more than a year now and think it's a great camera. I previously has the Pentax Pz-1p (film camera) and many of the features it had were carried over in the K-1 (e.g. ability to control aperture with an adjustment dial, ability to switch to Aperture or Shutter priority using the adjustment dials). One of the reasons I waited for the K-1 was to have a full-frame digital camera that equaled or exceeded most film in resolution and the K-1 does that pretty well. In fact, it exceeds the resolution ability of several of my lenses. It also has many advanced features like GPS, WiFi, and Liveview (with magnified focusing). There's somewhat of a learning curve for using the K-1 and there are lower cost alternatives but in terms of what you get, it's very cost effective.

For all-round use, I couple the K-1 with my old 28-200mm Pentax lens. That lens covers a wide range of focal lengths easily though it isn't the best in image quality and is slow compared to many prime lenses that can achieve f2.8 and faster. The K-1 somewhat makes up for that however in that shooting at high ISOs works remarkably well with the K-1. The anti-shake feature gains the equivalent of a couple of f stops also (not in all cases and not with moving objects in images). I have picked up a number of prime Pentax lenses which I am working with and finding they offer very high quality imaging with the K-1. My work tends to wide angle and some telephoto and I was lucky enough to get a Vivitar series 1 13mm lens which can capture details right up there with the K-1's abilities. Though manual focus, the K-1 makes that a breeze also. I also have a Tamron 90mm macro and it delivers knock-your-socks-off images so if you go with the Pentax 100mm macro, I'm sure you'll be happy.

Battery life is pretty good but get a spare battery because with digital cameras, batteries are the new film (in terms of consumables - though the batteries are rechargeable). I have dual 64GB SD cards which last forever with JPEG shots (I use one for simultaneous DNG and that does fill up more quickly).

Hope this gives you some new information or thoughts on the K-1. Again, welcome to the Pentax forum crowd.

Removing dust from viewfinder - K1 Mark II

I'd live with it and do as you propose. My experience with removing focus screens (and not the K1 variation with LCD elements) leads me to conclude that it is a risky process and you sometimes come away worse than you started. I would leave it to the professionals in this case.

What leads you to believe the dust is on the prism side of the focus screen? If the speck is in sharp focus, chances are it's on the image side of the screen.

Unexposed Film with Pentax ME Super
Posted By Bob 256
Replies: 19
Views: 459
From what you said, the other replies are spot on - the film didn't load properly and get pulled through for any exposures. I'm not sure about the ME, but my Pentax film camera has a sprocket wheel and it's important that the film engages that wheel well past the tip of the film when loading. If the wheel is engaged so it can pull the film, I've never had a failure. If the film lies short or off to the side of the sprocket, chances are, a bad load will happen.
