Corrupted Raw Files Pentax K-1

Are you sure that LR has the right version of Adobe Camera Raw to read K1 raw files?

Has LR *ever* been able to read the raw files from your K1?

Try shooting jpeg instead of raw and see if LR will accept that.

Try shooting raw in Adobe's DNG format, rather than Pentax's PEF format. If LR can read that, then you need to look at upgrading ACR in LR.

SD card Just bought an Sandisk Ultra SD XC1 64 Gig Card and comes up with error

I have a K10d and, as others have pointed out, the maximum size SD card it will accept is 32GB. The K10d does not have video capability.

That said, why would you want a 64BG card? When I shoot both JPG (minimum compression) and RAW images, the combined size is usually around 16MB for both the JPG and PEF versions. That means a 64GB card would be able to hold 4096 images.

If you only store JPG files, the number is a staggering 21,845 images.

In RAW only, you can get 5,041 images.

Halve all those figures for the capacity of a 32GB card. That's still a lot.

If I have time, I will partition a 4GB SD card into two 2GB partitions to see if the camera will even read the partition table.
I seldom use more than a 4GB card in my camera. I don't like to risk losing that many photos.

K5ii, Autofocus and and Aperture ring not working

I don't mean to be insulting, but you do realize that the aperture won't "stop down" until the moment of exposure, don't you? Try setting the shutter speed at 1 sec, and the aperture at f/16. Look into the lens while you trip the shutter. You should see the aperture close down to f/16 and re-open to f/1.8 when the shutter closes.

Are the pictures properly exposed?

My first "real" camera was a Spotmatic, of which the SP500 is a derivative. Great camera.

I suggest that you find a copy of Bryan Peterson's "Understanding Exposure". This book explains the "triangle" of film speed/shutter speed/aperture. It is an excellent tutorial for a beginner. It not only explains how to get a technically "correct" exposure, but also when you might want to use a different "artistic" equivalent exposure.

BTW, a bit of trivia about the SP500. There was another derivative of the Spotmatic, called the SP1000. The only difference between it and the SP500 was the 1/1000 shutter speed. In reality, the SP500 has the extra shutter setting as well. The shutter speed dial has one additional, unmarked click stop past the 500 stop. That is the 1/1000. It is my understanding that the SP500 and SP1000 are identical, except for the marking on the shutter speed dial.

That said, back in the day, if you returned your SP500, saying that the 1/1000 shutter speed was not working properly, they would not "repair" it. They would for an SP1000.

Your SP500 was originally sold with a 55mm, f/2 Super Takumar lens. Pentax made several lenses in 50 or 55mm focal lengths, including the marvelous 50mm, f/1.4. This range is the so-called "normal" lens, but, as someone else pointed out, your shooting style or subject matter may mean that some other focal length will be your normal. For example, if you shoot mostly landscapes, you might prefer a 35mm or 28mm wideangle lens. If you shoot birds in flight, a 200 or 300mm lens might be more appropriate. The 50mm-ish focal length is considered normal because most people find that it most closely captures the perspective of the human eye.

Be fair. Give the seller a chance to make things right. He may not know that it is not a Pentax mount.

If you get no satisfaction from the seller, then leave a bad review.

When I bought my Spotmatic in 1967, neither the SP500 or SP1000 were available. I probably would have bought one, as they were a little cheaper. I think I paid $220 for my Spotmatic with 55mm/1.8 lens. I really wanted the 50/1.4, but that was another $30. When you're a high school kid making $1.10/hour, that's a lot of money.

I have both an SV and an H1a (same as S1a), plus two Spotmatics. While I agree that the SV and H1a are good looking cameras, the Spotmatics are my favorite. To my eye, the lines are much cleaner, especially the contoured lens mount with hidden attachment screws.

The Spotmatic falls into my hands more comfortably than any camera I've ever held.

I may be biased, as one of the Spotmatics was the first high-quality camera I ever owned. I washed dishes and bussed tables all summer to save enough to buy it new, with the 55/1.8 lens, in 1967.

Have you got the shutter speed set faster than 1/180 sec? Pentax cameras will not fire the flash above that speed.

Pentax DID have a museum, in Tokyo, I think. They closed it down a few years ago.

I don't know what happened to the collection. Perhaps, now we know.

I do know that the museum had the AP-50 one-off that they built in 2007 to commemorate the 50th anniversary of the original Asahi Pentax SLR. It was a bone-stock K10d, with a silver top, that had no built-in flash and was styled like the pentaprism housing on tradition Pentax film slrs.

Pentax Spotmatic SP question
Posted By noblepa
Replies: 5
Views: 974
Can you reach in and gently pry the mirror down? Sometimes, with very old cameras like the Spotmatic, the foam cushion around the focusing screen, that is there to soften the blow when the mirror flips up, can get soft and sticky. Occasionally, the mirror will stick to the foam.

If it resists coming back down, then there is probably something broken or out of adjustment inside the camera. Having this fixed, if you can't do it yourself, may be more expensive than the camera is worth.

Congratulations. The K10d is a fine camera, although it is a little out of date.

As others have said, the Pentax software is not absolutely necessary.

As for transferring the photos from the camera to your computer, I do not use the USB cable on mine. I use the SD card slot on my computer. I do this for several reasons. One; I can never find the cable when I need it. Two; if you were to take your camera apart (please don't), you would see that the USB port is only attached to the motherboard by the soldered electrical connections. There is no physical strain relief. That means that it is easy to wiggle the connector enough that, over time, it breaks loose from the mb. When this happens, the cost of repair is much more ($300-400) than a K10d is worth.

Also, just a warning, the K10d only accepts SD, and SDHC cards. It does not accept SDXC cards. So, if you are tempted to spring for a new 64G or 128G card, don't waste your money. The K10d can't handle anything larger than 32G. That should be plenty. On my K10d, if I shoot in Raw+Jpeg, each image takes about 16M each (13M for raw and 3M for jpeg). That means I can get more than 500 images on an 8G card.

The last firmware update for the K10d was version 1.31. Hold the Menu key down while powering on the camera. It will flash the version currently loaded on the LCD screen for a few seconds, as it boots up. The updates are not absolutely necessary, either, but they do give additional flexibility with respect to the thumbwheels. Updates are available from Ricoh's website, along with instruction how to install it. The updates are cumulative, so if your camera is at 1.0, you do not need to load 1.1, 1.2, 1.3 before loading 1.31. Just install 1.31.

The K10d was, I think, the last Pentax to use a CCD sensor. Some people prefer the CCD's rendition of bright colors. In any case, the K10d does handle colors very nicely.

Probably the biggest shortcoming of the K10D is the high-ISO performance. While you can set the camera to ISO 1600, it gets pretty noisy, especially if the exposure is not perfect. I almost never use mine above 400.

Some might feel that 10MP is not enough, but I have blown images from mine up to 18 x 24, using 90 percent of the available image. From more than a foot or two away, they look fine.

Is it possible that the read-only switch on the SD card was accidentally turned on? Windows may detect that the card is in r/o mode and not give you the option to delete.

Honeywell (US Only) Spotmatics did not have "SP" engraved on the top plate, as the Asahi Pentax (everywhere else) versions did. Honeywell began engraving model designations with the SL and the SP II.

Spotmatic Battery Question.

Replies: 16

Its not a SP IIa. That camera had a flash sensor built into the left side (as you hold it) of the front of the camera, below and a little to the right of the rewind knob. It also had a hotshoe.

It was also clearly marked with "SP IIa" engraved on top between the prism and the rewind crank. His is clearly an ordinary Spotmatic.

My guess is that the base plate was replaced, for some reason, with one from a non-metered camera. The base plate from a Pentax SL would be a direct replacement. That camera was a Spotmatic with no meter. The base from an H or S series camera may also fit, but I'm not sure.

Fast lenses and F stops

To the OP: If you're still confused about aperture sizes (f/stops), I suggest you get a copy of Bryan Peterson's "Understanding Exposure". It explains how apertures are calculated, and how and when to use the various options.

As others have said, aperture size, among other thijngs, affects depth of field. Peterson explains the almost infinite combinations of "correct" exposure values for any situation, and then discusses which one to choose for the photographic effect you are looking for.

I've been an amateur photographer since 1967 and I still learn something from the book every time I look at it.

Super Takumars on Spotmatic F
Posted By noblepa
Replies: 11
Views: 785
There are a few of the later Super Takumars that have the open-aperture couplings for use on the Spotmatic F, ES and ES II. Technically the SMC designation refers to the improved, multi-layer lens coating. It just so happened that the open-aperture metering and the SMC coatings came to market around the same time.

I suspect that the SMC coatings were not quite ready for prime time, when the SP-F was introduced. Rather than wait for the new coatings, Pentax opted to add the coupling to the ST lenses, so they would have something to put on the SP-F. Remember, at the time, Pentax was being widely criticized for sticking with stop-down metering, while most other camera makers had come up with some form of open-aperture metering.

Spotmatic SP F vs F

I don't remember if Honeywell imported the Spotmatic F, or if it was introduced after Pentax set up their own import subsidiary.

I mention this because, in the Honeywell era, the plain old Spotmatic had no model designation engraved on the top plate, in the Honeywell version.

In the Asahi version, there was an SP engraved on the top plate. Honeywell may have carried forward the same quirk on the Spotmatic F.

Unlike the Spotmatic SP, on the Spotmatic F, that switch ONLY stops the lens down. The meter is on all the time. There is no way to turn the meter off. For that reason, a lens or body cap is imperative when the camera is not in use. Without it, the battery will almost surely be dead the next time you wish to use the camera.

I especially like using the 50mm, f/1.4 Super Takumar from my Spotmatic on my K10d.

Having cut my photographic teeth on a Spotmatic, manual focusing and stop-down metering don't bother me in the slightest.
