ISO3200...It's Actually Not Bad...

To me the 2nd doesn't look properly white balanced. Bad white balance can mean bad exposure in my experience. I completely agree with others in prior posts that a good exposure at high iso is quite clean! A good exposure at -1, if really nailed at -1, but properly exposed, should push very well. Even in the k10d (though not as good as K100d)!

Question about Ansel Adams books

With all the examples of his work, philosophical discussion, instruction and anecdotes, even if one never touches developer, these are great books to have. I think Ansel would have loved working with RAW!

K10d Autofocus Tracking

I've really changed my mind about the tracking capability of the K10d. While it isn't perfect in every situation, what actually made it work for me was turning on all focus points, as recommended in one of the forums. If you can lock on a target, then it will keep it in focus. Center focus AF-C is frustration itself.

anyone had pentax map out stuck pixels?

Jonrkc, you may be on to something!!! I just tried it and I am not seeing my hot pixel. I tried in jpg mode (not raw), all the way up to 1600. I'll have to try with some more photos but can anyone else confirm. I made sure noise reduction was off!

If this is true, this is outstanding.

focus with k10d and smc-m lenses?

Focus confirmation tolerance too wide but wide open manual focus isn't hard. Most critical thing to have a chance for me was to adjust diopter! After that, a breeze. APS sized sensor with 10MP makes very accurate focusing more critical than 35mm film.

Low light is great if appropriate exposures can be made. Push processing can create very poor results but depends on the subject matter. There, I'm starting to learn that this is true of other cams, too. I've had more chance to use a Canon recently and in low light, proper exposure is just as critical.

Katz Eye vs. Haoda vs. Chinese eBay focus scree

I was't going to reply on this thread as I only have used one, a Chinese version. A few things. First, they are bloody great for accurate focus. Unfortunately my targets are often moving, so I ended up reverting back to the easier to use regular screen. I do keep the split on hand.

Issues I had included metering. Even if using regular matrix metering, the results were often off by different amounts. It's not as easy as a simple exposure comp.

I used at 300+ mm with up to F5.6 lenses. The "blackout" is actually not as insidious as it sounds, from my view. If you look directly through the screen, it doesn't black out hardly at all, even at 5.6. It takes getting used to but it isn't so bad.

But I really responded as I would encourage you to research the Katz Eye "ultra bright" or whatever option that is. See if users have found that that has less impact on exposure as that's my biggest beef with the Chinese version and if really effective, would be worth twice what they charge for it, seriously!

K10D performance at ISO 1600

I'd have to say this is a most useful post on the K10d. It is very much validated. It's counterintuitive, but I often get better shots at ISO 800 than ISO 400 due to the combination of exposure and shutter speed to minimize motion blur. Add SR and it's a killer combo!

Push processing is still useful but exacting white balance and manual metering can help make that more successful.

K10D at iso 1600

Jgredline, that's good to know on the Nikon, though I have seen some very convincing comparisons. With the Canons, yes, much first hand experience. The biggest diff is in dynamic range and VPN. Dynamic range is especially critical as developing RAW on difficult photos means results can be more prone to VPN. Also, chroma noise is significantly worse. Again, the samples shown in this particular thread are not very complimentary of the noise, but I also agree with OP that it doesn't necessarily degrade the image.

I just looked at two of my own images between the Canon 30d and the K10d (I have quite a few to compare but selected two), ISO 1600, 100% crops. To be honest, it isn't that much of a difference aesthetically, but when you consider the VPN and noise in a lot of images (dark areas), I still say the Canon is appreciably better. Again, it was not enough to prevent me from buying the Pentax.

K10D at iso 1600

As I recall that is much better performance at ISO 1600 than film, but the fact is, the Nikon and Canon entery levels beat the K10d by a mile (in high iso), so the K10d is not competitive in that respect. As a consumer, I accepted that, but I'm not saying that it's ok. If pentax is not going to be competitive, they aren't going to win in the long haul.

I remember the interviews of the Japanese designers when the K10d was being developed. They indicated that they had trouble maintaining quality with the range of ISOs needed with that deisgn. Why not use a tried and true design like a CMOS? They made decisions that will have lasting impacts. Even the die hard fan boys are getting perturbed with the lens availability issues. I am still rooting for Pentax to pull it together.

BTW, one can always make a clean image noisier but not the other way around.

The Pharos - Britain's oldest standing Roman building

Neat shots. Without the story they may just be non descript castle pics, but the Roman element is very cool.

I like the exposures more or less. Some perspective adjustment may be useful on some, esp the 4th one.

There is tilt in the water line in the image with the ship. Again, those are tough with a 2 dimensional lens but there's usually a happy medium.

K10 auto focus issues

Suggesting MF as a workaround should be a shame to Pentax. AFC is very poor compared to others like the D80 and XTi. I hope Pentax is listening. I wonder if back/front focus could be making it worse.

Neat pano of the road. Good color rendition. King's and Sequoia can be very difficult due to haze so I think you did very well.

Is that third image the right one? The left side in the first image looks well exposed, so I'd focus on the darker side. A mask would be more effective here, IMHO.
