Brand new K-5... dust under LCD glass. Now what?

Yesterday, I received my K-5 from B&H, and right out of the box, it unfortunately had a fairly large piece of dust under the rear LCD glass (picture attached below, but I don't know how easy it will be to see on the web). It was even noticeable when the LCD was turned on at normal brightness. I'm worried that it might have to do with a problem with how the LCD glass was sealed, as I read in another thread that people had related dust problems. Or, it could have accidentally gotten under there during the assembly process. Either way, I plan to get it exchanged. With B&H closed for the holiday, I feel like it will probably take a fairly long time to get this replaced. Does anyone know if I can still begin the exchange process even while B&H is closed so that they can ship a new one as soon as they open again on the 15th?

This is quite frustrating as I was really looking forward to using my new K-5, and now I have to wait even longer.

If anyone has any other suggestions/advice for me, I would appreciate it. This is the first time that I have needed to exchange something.

Does it matter when my K5 was made?

I just received my K-5 from B&H today and it was also manufactured in September 2011 with a shutter count of 1 (the test shot). I haven't used the camera yet other than to get the shutter count and manufacturing date, but I did notice that there seems to be a speck of dust underneath the rear LCD glass and I had just taken it out of the box for the first time. My K-x (2+ years old) has no dust under the LCD. I'll have to figure out what to do about that later today...

I don't often see mention of Pentax on the internet outside of these forums, but I came across this, and it sure was a delight (and a good laugh).

Shooting on a cool/foggy morning.

Thanks for the info, both of you. I think I'm finally starting to wrap my mind around the whole "science" of when condensation occurs on the lens/camera. The forecast for tomorrow has changed, and it looks like it will start raining earlier in the day, so I may end up staying inside after all, but now I will feel more comfortable taking my camera out in the cold on other days when it's not raining.

Hey everyone,

I'm planning to go out this Sunday and take some pictures of the morning fog with my K-x and DA 15 (& maybe DA 40). The forecast for that morning is around 40F with close to 100% humidity (it's raining on and off this week, but there shouldn't be any rain when I go out), and this will be my first time taking my camera out in cooler weather. I've read a bunch of threads and articles about protecting gear in humid environments, but most talk about extreme cold and the hot/humid tropics. Since I'm not in a snowy or tropical environment, do I need to worry too much about condensation becoming a problem? I'm especially worried about condensation inside my lenses, but maybe I'm worrying too much. I was thinking of just bringing a ziplock bag to keep my camera in when going outside and when going back inside, as this seems to be many people's basic procedure. Perhaps someone can provide some reassurance that I shouldn't have any issues, as I'd really love to go out and get some unique shots now that the wintery/foggy/rainy season is beginning. Also, any other tips for shooting in this kind of weather would be appreciated.

How to blur moving water

I'm curious about the VF affecting exposure as well since I'm going to be experimenting with daytime long exposures very soon. If the VF cap/tape/whatever is only to keep excess light out when metering in an auto mode, would it work just as well to use the AE lock button and then not have to worry about a cap for the VF?

DA 15mm Ltd. Alternative Lens Cap

Thanks for confirming that about the pinch cap.

I actually still have the original cap that came with the lens, so I don't need a replacement. Rather, I'm interested in finding a snap on cap to use since the screw on cap is sometimes a bit inconvenient. I've read about other people doing this on these forums (and I've done a similar thing with the small screw on cap on my DA 40). I'll continue to look in the rest of the forums to see what other people have said about this.

Thanks again for the help.

DA 15mm Ltd. Alternative Lens Cap
Posted By jcob

I'm looking for a 49mm lens cap (specifically one made by Pentax) alternative to the screw-on one on my DA15 for ease of use, and I had a few questions about B&H's offerings. I found two different lens caps available:

1) a pinch-type cap: Pentax 49mm Snap-On Lens Cap 31526 B&H Photo Video

2) a standard snap-on cap: Pentax 49mm Snap-On Lens Cap 31491 B&H Photo Video

Firstly, I wanted to know if the pinch cap (which is the same type as the caps for my kit lenses) is as pictured. As far as I could tell from looking around the web, no one else offers this style of pinch cap from Pentax in the 49mm size (not even from the official Pentax web store), and I don't even know what lens from Pentax ships with one of these. So, if they really do make these types of caps in the 49mm size, then that's great.

The second thing I was wondering was whether the pinch cap would be better for the DA15 since the retracted hood still protrudes slightly on the top and bottom edge, or if the other standard snap-on cap is still just as easy to get on and off this specific lens. Also, I'm just slightly concerned about whether or not these two caps might scratch or touch the front element of the lens, so if you have any info on that, I would appreciate it.

Thanks for all the help!

Using Polarizer as an ND Filter?
Posted By jcob

I should probably mention, though, that I had to stop down the aperture all the way. I was doing a test of my daylight long-exposure setup to see if I could get movement in clouds but I don't think 3 seconds is long enough for me (there was barely any wind, though).

I'm not too sure about the quality between different brands. I've only used Hoya filters and I haven't had any problems as far as I can tell (I think the 52mm CPL I got was about $45, if I remember correctly). I'm still fairly new to DSLRs so I don't know if I would be able to pick up on quality of filters as much as others would. But just from what I've seem, B+W filters seem to be popular so I would assume that they are higher end filters (especially since they tend to be more pricey) and they seem to have a better build quality than other brands. Definitely do some research on the different brands. Sometimes, you have to pay more to get better quality but that's not always the case.

Best of luck, though. Long exposures are quite fun to play around with.

A polarizer will definitely reduce the light going through the lens a little bit, but it's not really enough to do long exposures during daylight by itself (depending on how long of an exposure you want to do). I've used 2 stop and 3 stop ND filters with a CPL before and still have only been able to get about a 3-second exposure in daylight. I've also read, though, that you can stack two polarizers to make a "variable" ND filter and rotate the polarizers to change how strong it is. That's definitely something that you should look into, since it will probably be cheaper than getting a bunch of ND filters. But again, it depends on the conditions that you are shooting in and how long of an exposure that you want.

newbie question about remote usage on k-x

I just checked all the modes and the only ones that it won't work with are "sports" and the "kids" and "pets" scene modes because they all force HI continuous shooting (for obvious reasons).

is K-X Live View quirky about focusing?

Just the other day, one of my cats was sitting in my windowsill so I couldn't use the viewfinder to take a picture head on. What I did instead was use live view to frame the shot, then I held the camera steady and switched out of live view to focus and take the shot. So that's another way to use it without having to deal with the slow focus speed.

K-x long exposure/dark frame/low batteries
Posted By jcob
Replies: 2
Views: 3,181

I set my K-x up and took an 8 minute exposure, and then I think the batteries (eneloops) died at some point near the very end of the exposure or during the dark frame (the aperture was still closed down as it was for the exposure, if that helps to determine during which stage the batteries died). At first, I didn't realize it because I just assumed that it was doing its normal processing thing or whatever that usually happens after long exposures (I think I was hearing the sound of the SR). I kept the timer I had going for the exposure on the whole time, and once it started to near 16 minutes total (8-minute exposure + 8-minute dark frame), I started to get concerned that something was wrong when the camera didn't stop doing it's thing. Anyway, I was worried that taking the batteries out might damage the camera, so I searched up any threads pertaining to this. I stumbled upon a thread about the shutter operating nonstop when the battery ran low in someones K200D, I think it was, and figured that the only thing I could do was take my batteries out. So that's what I did after about 35 minutes total since I started the exposure (I know, it's a long time between realizing there was a problem and finally solving it).

Anyway, sorry for the long intro... my question is will having the camera operate like this (stuck doing the dark frame after batteries run out) damage the sensor/camera?

Also, a related question... I've tried turning off the slow shutter speed NR, but it still seems to do the dark frame thing after long exposures, though not for the same length of time as the exposure was. Is this to be expected for all long exposures (i.e. giving the camera time to process them) or can something be done in the settings so that I can take a long exposure and be able to take another one right after the first one ended without having to wait for the camera to process or do whatever it's doing?

Thank you for all your help.
