Realignment of K10D SD card slot without sending it back to Pentax?

I have a K10D that seems to be trying to eat SD cards ever since I got it back from Pentax service. They replaced the sensor and/or circuit board (their words) and I've had two issues nagging the camera since then. One is it will not turn off no matter what position the switch is in. That seems to have gone away with use, but the other hasn't. The SD card slot doesn't seem to be aligned with the hole in the body. The card with rub its label side on the body of the camera, and is difficult to seat home and release. During the release push and click, it sticks for a bit and then pops out. I had a Corsair SD card crack horizontally a couple of weeks back, and this happens with different cards.

Is there any way to correct this without having to send it back to Pentax again? Are there any body diagrams or blow-ups floating around?

I just ordered and received two batteries and grip from Cameta Camera. It was my fault for not checking beforehand if they were Pentax, but the description was throwing around the Pentax part number.

They showed up today and they're CTA at 1350mAh. I'm split between keeping them and sending them back. Since it was a kit, they won't just take the batteries back and let me keep the grip. I'm short on time when I need the extra batteries, so I'm about to charge them up and put them through their paces to see how many shots I can get per charge.

I want to thank everybody for their help. I finally got to shoot test shots this week of people playing the game and inside the building where we will hold the competition. 30mm would have been very tight, turns out there is about 3-4 feet worth of cable between the game system (PlayStation 2) and the "guitar" (the game is Guitar Hero II). My 50mm framed just the head and shoulders. I will need pictures of their whole body.

It came down to the Pentax 14mm 2.8 and the Sigma 18-50mm 2.8. Not as fast as the Sigma 30mm 1.4 or the 31mm Limited, but the building we'll be in is very small. These are turn of the century (circa 1900) storefronts, and they are tight inside, especially with the amount of people we're expecting. There are actually two contests being held inside the building. Unfortunately the electricity was turned off when we visited, but the whole space is lit with overhead fluorescent lights with a few incandescent light bulbs thrown in here and there.

To amuse myself I called all the Dallas area camera stores for a DA* 16-50mm, and to my surprise Cooter's Village Camera had one in stock. They also have a 50-135mm in stock, too. I picked it up today and have been shooting ever since I got back. Its a nice store, the salesman even put the lens on a K10D so I could play with it since I forgot my camera. Might not seem unusual, but I've been to another local store when I was looking at K10Ds and the salesman was more interested in playing with the camera than actually letting me try it out. I even got to play with the 50-135mm a bit. And the price was $100 less than B&H and Amazon's price. Well, that is if they had the lens in stock.

713alan, the tripod idea is a good one. I was thinking the same thing, especially for the finals. We'll have a stage setup, and there is a nook tucked away at the back corner of the building next to the stage where I can cordon off an area and shoot. It'll also allow me to get some crowd reaction shots, since part of the competition is costumes and playing the part of a rock star. We don't want people to just stare at the screen and play, you have to entertain the crowd.

Well, then I stand corrected. The Wikipedia article and ones linked off of it were helpful. :)

The flash is for room-wide shots of people inbetween matches, and for the awards ceremony after the tournament. I can't use the flash during the actual video games. I'll be able to get to the side but not in front of the players because they have to watch the screen while playing the game. Either way, a flash no matter where I stand is not going to work because it will be distracting when the players are concentrating on the game. Hence, the need for the fast(er) lens. Most likely the light I will have now is overhead fluorescents and the light thrown from a LCD TV.

Correct me if I am wrong, but since the Tamron is a DI lens and not a DI-II, it is full-frame. So 28mm on that lens would be 45mm at the wide end.

I found out today the tournament will not be held in the theatre, and we don't really know where it will be right now. One thing for sure is a walk-up tournament will be outside on the street, and the pre-register tournament will most likely be inside a building. The building choices we have will present low light or harsh fluorescent lighting conditions.

I work for an organization that is putting on a video game tournament in a small theatre (with a stage, not a screen). I have volunteered to take pictures of this tournament. My problem lies my my current kit, which is a K10D, 18-55mm, 55-200mm, and 50mm 1.4. I have already ordered a AF-540FGZ, but my question is the lens.

I don't have access to the theatre yet, but I plan on taking test shots with the current lighting setup and hopefully the new lighting setup when it is installed. Right now I don't know if my 50mm will be wide enough for the venue right now. Most likely it will not. There will be TVs in front of the contestants so I plan on getting to the side or in front (and below, to not block the contestant's view) of the contestants. There will be perhaps three or so feet distance between the contestant and TV.

I am trying to decide on a lens for this, and I narrowed it down to the Pentax 16-45mm F4 or the Sigma 18-50mm F2.8 EX DC Macro. I don't have enough time to wait for the SDM lens, as the tournament is the middle of September. Am I in the right vicinity with these two lenses or is there something else that I have missed? Perhaps even wider with the Sigma 10-20mm because of how close I will be? My only concern is the small zoom range and slow aperture, as I will not have a second body to mount a longer lens. I do have a Panasonic Lumix FZ8 I could use for the longer shots, but it doesn't do well in low light.

Strange problems with my K10D

I took pictures at a wedding and all the images seem to me to be unusable. All were with a FA 50mm f/1.4 lens, and the noise (all at ISO 800, 1/60, f/4-4.5, flash) is heavy. Black tuxedos aren't really black, they just have a pattern across the fabric. It looks somewhat the moire pattern in examples in the first post, but seems to repeat itself two or three times across the frame. I think I may send my camera in to have Pentax take a look at it. I've run into a wall in respect of my ability to determine if it is me or the camera itself. But now I have about 101 examples of my problem.

I wasn't aware that CA could appear like this, I thought it was only a problem in situations like the tree branch that you describe.



More the cabinet area, but I was also surprised at the amount of general noise in that shot. It seems hit or miss with me, some ISO 800 shots will turn out fine, some like this. This is the first time I've seen the moire effect, but I have had some vertical pattern noise appear in some of my shots. I never use ISO 1600, its happened at ISO 800 mostly.



Part of the reason for this thread was to help my decision to send the camera in or not to be checked by Pentax. Mine is a early production example, and I've had some other issues crop up but I've never been sure if it was just an anomaly, or something wrong with the camera itself. It is difficult to judge with my limited experience.



No, the mazes appear in the RAW (shot as DNG). I was just shooting RAW at the time, no JPEG. This particular image was converted by ACR 4.1 and saved by CS3 as a 100% quality JPEG. If anything they're more apparent in the RAW shots. When I was making this example I was worried that JPEG compression would mask the mazes if turned down the quality.

I've had my K10D since November and I'm trying to work through some problems that keep cropping up with it. Now I will readily admit I'm most likely the source of them as I realized once I used it for awhile that it way too much camera for me. I had a Nikon D50 before this, and sold it for the K10D's anti-shake as my hands are none too steady. I'm trying to work my way up the level needed to utilize this camera.

My most recent issue is when I was taking pictures of my K1000, purple "mazes" appeared at two areas, one across the shutter button barrel, and across the "Pentax" label on the front of the camera. Now I shot these in RAW, and using Raw Photo Processor there was no purple mazes, but with ACR 4.1 and Pentax Photo Laboratory, there was. Here is an JPEG example of it, saved from CS3:

This example of (what I think) is excess noise. ISO 800 with a flash, I cropped this to show the pattern noise in the background of this picture.

https://www.pentaxforums.com/gallery/index.php?n=2449

Now I know these are crops and could be considered pixel peeping, but the purple mazes were apparent to me without zooming into the message. I also have an example of pattern noise in a ISO 400 shot if I can dig it up. With this said, is it me? I can supply the EXIF information it would make the determination easier.

Good place to buy K10D?

I came here to recommend Beach Camera, which Buydig is their sister site. Seems that Beach doesn't carry the K10D anymore. I purchased my K10D from them when they were out of stock everywhere else. I have purchase three cameras (Olympus C-7070WZ, Nikon D50, K10D) from Beach and have had no problems.
