K10 compared to DL
This might seem like a stupid question........ The K10 is on offer at a very low price at the moment, and I am tempted to upgrade from my DL. Obviosly the K10 is a better quality camera with many more features and better performance, but will I notice an increase in image quality at 10x8 from...

To Shake or not to Shake
I agree with Martin about many things, but not on this occasion. First it's important to note that in many of the cases where you'd be using the K10D on a tripod, the camera itself turns SR off. So if you're using the self-timer, the 2s delay, remote control shooting, the remote 3s delay, bulb...

To Shake or not to Shake
I leave the sr off unless/until I know I need it. reason: I can see the difference. I have actually tested and found that in some instances, I'm losing sharpness on handheld shots in low light. It seems that the camera tries to compensate, in areas where my hands are steady enough. (even started ...

Does your K10D's auto-focusing ever do this?
I suppose they know more that I, but logically it don't make a lot of sense to me. I would assume that in addition to aperture, the subject distance would need to be known to correctly adjust for aberrations. There would be a few points on a graph that it would "know" about. Anything ...

Cleaning the Sensor of K10D
I have managed to bag a Vivitar 1:1 100mm f2/8 macro lens off Ebay for a stupidly low price but getting up close shows all the specks on my sensor. Shot was hand held with no cropping, I presume all the little bits are dust. http://farm3.static.flickr.com/2030/2531037234_cd7aafc0c6_o.jpg Wh...

Cleaning the Sensor of K10D
Try this thread: https://www.pentaxuser.com/forum/viewtopic.php?t=7523 Btw - your picture is huge - difficult to say what those specs are. Could be dust inside the lens as well. Try put one a different lens to check it.

Cleaning the Sensor of K10D
Thanks, will take a look. Wanted the picture as large as possible to show the particles in question. Got a rocket blower yesterday and gave that a go but its not really for the sensor so not much good, but it did get out a lot of the dust I aquired when fitting a new focus screen from ebay, then...

Cleaning the Sensor of K10D
Yes, you have dust and marks on the sensor. Some will just blow off, some may need more thorough cleaning.

Cleaning the Sensor of K10D
Got a rocket blower yesterday and gave that a go but its not really for the sensor so not much good... I use mine on my K10D sensor all the time and it's fine. Certainly that looks like dust on the sensor, but it's not your new lens that's showing it up, just that you're using a small aperture, in ...

Cleaning the Sensor of K10D
To clean my sensor I use:- Rocket blower > Arctic Butterfly > Rocket blower I've never had to wet clean my K10D sensor since I bought it in Jan 2007.

Cleaning the Sensor of K10D
What appear as blobs with rings around them, in my experience, are not simply loose specks of dust on the sensor that can be blown off. I have managed to get these marks off with a SensorKlear pen, and cotton bud, after breathing on the sensor. I've then needed to get stuff that has shed from th...

What's happening here?
Just thinking about this, the wheels are shiny and shaped, there is a chance that they are reflecting light only from certain positions as they rotate. If this is true, you wouldn't need SR to produce the effect - effectively the wheel is causing its own strobe effect (ie a flash only in certain ori...

What's happening here?
if the sensor is being moved up and down then it must stop at each extreme and so 'burn' a stronger image onto the sensor at that moment. Still can' figure it out tho', I'm just going to do it again in the same situation with the SR off. if it continues to do it then my money is on the 'facets of...

What's happening here?
Aj, I think yours is the sun catching each spoke and making a pretty and consistent patern. I went out again today and took a load of images mostly SR off (no difference) and at different speeds and the slow ones definately show this the best. I think when you pan smoothly, there is always a part ...

What's happening here?
I think when you pan smoothly, there is always a part of the wheel (particularly the bottom part attached to the road - not moving up or down or against the direction of the road) that is effectively stationary to the sensor or scribing a smooth image across it. But because there are several spokes...

A closer look at Shake Reduction on the K10D
You may remember that I threatened to do a bit more of a careful investigation into the allegation that shake reduction on the K10D causes shake when the camera is still. Well I have, and the results are in. For those that just want the bottom line: - If you want to eliminate shake on a tri...

Cleaning behind the focus screen.
Like an idiot I purchased a split focus screen for my K10D to aid manual focus macro stuff and it was basically a load of rubbish so I put back the original. I now have half a ton of dust behind the screen and a ruddy great fingerprint on the screen itself (sigh). So anyway, I am going to buy my...
