K10D vs K20D
Between the K20D and K200D? I can't see it myself, but then I'm no expert in these things. I would say they've got such a camera at the moment, and it's called the K10D. They haven't got the K10D any more. It is discontinued. You can still find stocks of it at the moment, but no more will be mad...

Is my AF540 flashgun....on strike, or what?
I hate when people ask a question is a forum, then figure out the problem, and then never report back with how to fix the problem. People reading this thread get no useful information then! Well I'm going to dig up this dead old thread to say this: The problem was that I was firing my flash a ...

K20D review in next week's AP - 8th April
I don't have it in front of me so won't attempt direct quotes. Main points though were that they had issues with the AF performance, the Live View mode isn't as sophisticated as others and there is evidence of some purple fringing on some shots, eg with trees against a bright sky, that may be due t...

Not sharp
There's the effect of a small sensor to consider too; the sensor in the Panasonic is much smaller than that in the K20D meaning that the depth of field (area in focus) is much greater at any given aperture. If your focus is off by a small amount then it'll be quite obvious on a DSLR whereas compa...

I moved from a bridge camera some time ago & went through exactly the same thought process... The lenses attached to decent bridge cameras usually out-perform the "budget" kit lenses supplied with DSLRs - I immediately upgraded my kit to the Sigma 17-70 & the difference was eno...

K10D/GX10 dust prevention system - seems to work
Every now & again I routinely check my GX10 sensor for dust and after 8 months of ownership & some lens changing I've not encountered anything significant - I've performed a quick blast with the rocket blower only once. The conclusion I draw from this is that the dust prevention must be r...

K10D/GX10 dust prevention system - seems to work
DR on my K10D has done absolutely nothing to remove dust from my sensor. I've had to remove both small and large particles manually. I reckon DR is a more a marketing gimmick than anything else. The other brands have it, so Pentax has to have it too.

K10D/GX10 dust prevention system - seems to work
I don't think the shakey dust remover thing works particularly well. HOWEVER. DR isn't just that, the sensor is also coated to repel dust from sticking in the first place. My K10D is dramatically less susceptible to sensor dust than my *istDL2, even though the latter gets fewer lens changes than ...

How Likely am i to get dust on my sensor?
I have only one lens from K10d at the moment and dont intend to change it for a long time , therefore the lens will not be removed from the camera , my photography takes me to the coast , woods , citycentres just about anywhere really - is it still likely i will get dust on my sensor if the lens nev...

How Likely am i to get dust on my sensor?
It's incredibly unlikely, but even Pentax would not say that it is totally impossible. You haven't said which lens you have, if it's a DA* weather sealed lens, I'd say you'll have no problem. The coast + city centres = sand + debris + very fine dust. If it's not a weather/dust sealed lens, you...

How Likely am i to get dust on my sensor?
Is internal focusing or does the lens mechanically move in and out to Zoom or to Focus? Some lenses cause a mild vacuum action as their parts "zoom" in and out, often sucking dust directly into your camera. So in that case, probably 100%. But how long it will take until something sign...

How Likely am i to get dust on my sensor?
It is always possible that there is a bit of debris already in the camera that will one day fall onto the sensor.

How Likely am i to get dust on my sensor?
Then lets say 100% chance. But over what time frame? Who knows. Could be a while. Really depends on the environment (sandy beach, dusty race track, or clean room?). I was on two week vacation on boat and land with a sigma 18-200 lens (kept the same lens on). Never had a problem with noticeabl...

How Likely am i to get dust on my sensor?
I would not obsess over it. Even a little dust is easy to get rid of with a blast of air, or later through Photoshop... although perhaps a little irritating on a thousand+ photos from a trip. software like aperture allows you to clone/heal out the dust spots on one image then "lift" the co...

How Likely am i to get dust on my sensor?
I have an IST Ds, (still :roll: ) so no dust removal system. I have taken it to dust laden Tanzania, whale watching in the US to our local sand dunes, sailing and on beaches. I change lenses frequently. Yet I only got dust on my sensor to the degree of it being annoying more than 18 months after fir...

How Likely am i to get dust on my sensor?
A tip for those at risk of becoming obsessed with sensor cleanliness: Do not test by photographing a white piece of paper (over-exposed) at F32. It will show up every minute imperfection and you will go nuts trying to get rid of all of it. Test at F22 or F16 instead. Better still, don't test...

How Likely am i to get dust on my sensor?
Do not test … at F32. It will show up every minute imperfection … Test at F22 or F16 instead. I have read this often and observed it in experience, but in my simplicity I don't understand why small apertures make dust on the sensor more visible. Please can someone enlighten me? Michael
