Thanks for all the replies. I think I've decided to go with the 55-300.

I'm sure I'll have more questions before I actually take the plunge!

I've been having some trouble deciding on which of these lenses to get. The only lens I currently have is the kit 18-55 lens. In this sense the 55-300 would compliment this quite nicely. However the 18-250 could just be my only lens.

Anyone have experience with both of these and have any comments?

Is the image quality better on one vs the other?

Again, any input on this matter would be greatly appreciate.

Thanks,
Vyx

Concerns with new K10D

When I checked the export dialog in lightroom, the minimize embedded metadata was not checked so I just copy and pasted the info from the properties link on the right side of the flickr page into the comment boxes. I think this is what you are looking for. If not, please let me know.


Just when I was beginning to think that my camera was fine you start to get me worried again :(

Would there be a way to test the camera to see if it had an underexposing problem and if so, how would I fix this? Is there some setting in the camera that I can change or would this be something that I would have to send the camera into pentax to repair?

Thanks again for everyone's help,
Vyx

Well, thats reassuring.

Also, on a side note, if others with the K10D wouldn't mind looking at the 2 examples (ISO 800 and 1600) and telling me if these seem about on par with what your getting I would appreciate it.

I made a little setup in my living room to do this. Although not the best lighting conditions I think it illustrated the point you were trying to get across. I took shots through the iso range and the results were much closer to what I had expected. ISO 1600 yeilded noise but for that ISO, I think it was acceptable. I have an ISO 800 and 1600 shot up on the flickr page.


Thanks for the advise jeda, after I bumped the sharpness up in camera that helped the pictures a bunch. Although, I think that the kit lens is still limiting in how sharp I can get the pictures.


Currently I'm using multi-segment metering.


I think that most of my problems stem from inexperience. I just started freaking out when my camera didn't do exactly what I thought it would out of the box. Since this was a huge purchase for me I started to think there might be a problem with the camera but well...I think its just operator error. But as always, any advise is greatly appreciated.

Thanks,
Vyx

I've uploaded two more images. One the same image without any pp, just jpg conversion and another taken at the same time. Although not as apparent, it still seems like there is banding to me.

When I take off the lens I still see the specs when looking through the viewfinder. I've looked on the mirror (this is the part thats down when you take off the lens right) and it seems that there are a few small specs on there, I suppose that could be where the problem lies.

I agree with your first four points and that is probably where the problems are coming from although, I do have SR on. As to the 5th point, I guess my question is this: Before I bought my camera, I looked at many reviews. Many of them would take a still life photo of a bunch of stuff. They would then crop out a portion of the image and blow it up yet everything still looked sharp. ie. This page on dpreview. Also, when I stated that my images at full size are not very sharp, I mean like this. On that page, the image is the full 10mpix resolution so that I have to scroll up/down and right/left on my screen. When I open up a raw -> jpg conversion on my computer I have to scroll the same ammount, hence the two images are the same size yet mine are nowhere near as sharp as the example. I purport that this could be caused by me. I don't have a tripod, but I'll try taking some tomorrow with the camera braced and see what I can come up with.

Thanks again,
Vyx

Concerns with new K10D

Well, I finally got my K10D and I've been taking alot of pictures lately. Mostly on the green mode as I have no real experiance with cameras but slowly experimenting with the other modes. All of the following is with the Kit 18-55 Lens.

What concerns me is that my pictures don't seem to be giving me the quality I had hoped for.

The first problem I see is that I took a few pics at ISO 800 and some seem to turn out horribly and others are alright.
Alright example ... Horrible Example (has some brightening in lightroom) In the horrible example, you can clearly see that on the right side there is a bunch of banding and that there is also a high amount of noise throughout the photo. I figured that I would get noise at ISO 1600 but I shouldn't be getting this kind of noise at ISO 800 should I?

The other thing is that my picture seem not to be very sharp when I view the @ 100%. There are a few other pics I've uploaded on the flickr page. They seem to be fine when not viewed full size and its kinda hard to tell on flickr but on my computer I can clearly see that they aren't very sharp when viewed full size. Would this be me, the camera, the lens, or something else?

The third thing that mildly concerned me, although not to do with picture quality is that when I look through the viewfinder I can see these 3 specs of dust. It was like this fresh out of the packaging. They are always in focus, even when I zoom in/out and change the focus. Does this give any indication of where they could be? Sensor, Viewfinder, Lens?

I just spent a lot of money (for me) and I'm mildly dissapointed. Any advise would be greatly appreciated.

Thanks,
Vyx

Edit: Forgot to mentions, all of the photos are taken in raw and then converted with lightroom to .jpg

Alright, good to know. I keep reading mediocre things about the kit lens that comes with the camera (which is the only one I'll have for a while anyway). But after seeing those pictures, I guess it just takes some practice to get nice pictures.

Hey hows everyone doing. I just ordered my K10D. I'm very excited to get into photography and have been for a while, I just now happened to have the money to get a camera. Now the waiting game. I've been reading everything that I can on taking photos so hopefully I will have a bit of a head start.

Hey, great photos Pete. I am actually about to get my K10D in, just ordered it and hopefully I can take some photos that are even close in comparison to yours. Which lens were you using? If different ones, I was specifically interested in the first 3 shots.

Thanks,
Brandon
