Shooting directly into the sun can damage sensor?
In snappychappy's rather effective shot above there is some of the Sun showing through the branches. For the small area of the sensor that is falling on it is exactly as bright as the rest of the Sun, so it doesn't matter if it is the whole Sun or just a part - if it was going to damage the sensor ...

Shooting directly into the sun can damage sensor?
I'm sure that looking at the sun through a camera isn't good for human eyes either. I can vouch for this - tracking a Red Arrow at an airshow last year at 500mm, he flew past the sun and I got a magnified eye-full. I was quite dazzled for a while but there was no permanent damage.

Shooting directly into the sun can damage sensor?
Sod the sensor, think about your eyes, they are irreplaceable. Sensors are ten a penny in comparison. Take care.

Shooting directly into the sun can damage sensor?
I would say that 50 percent of my shots outdoors are into the sun. No problems yet.

K5 Serial Numbers?
I might just be thinking of a K5 and ask does anybody know when the old numbers which had the dirty sensor stopped and the new numbers started with the clean sensor? I'd hate to buy one which might be old stock because I'm sure there must still be some around. CHEERS Vic. P.S. I have the genuine...

K5 Serial Numbers?
I'm not sure the serial number helps much. My replacement K-5 sits firmly in that time and serial number range still but is stain free. If you buy from a reputable dealer with a good turn-over you are extremely unlikely to end up with one in the sensor stain time range. Even if you are really...

I took a pic at iso 200 and printed it at A2 after sharpening and contrast boost it was on a 12mp sensor and turned out fine:-) with an expected little loss in detail(perceived) Dan

digital vs film for sharpness
Thanks John. I know we can sharpen or soften in post process -indeed on jpeg the camera has sharpening levels which we can also vary. My quandry is why would we need to. If the sensor is like a film and the image is focused perfectly on its surface then the result without digital manipulation m...

digital vs film for sharpness
It's a fair question and the answer lies in how a digital image is produced. The image is slightly softened to prevent moire effects and therefore needs to be sharpened after capture. There's no right or wrong about it and not really any sort of purist approach, it's just how the system works. Ba...

digital vs film for sharpness
Unlike a film, which has a random silver halide cristal surface, the digital sensor has a very precise grid of light collectors. That grid will interact with some other man made objects which form a regular pattern, creating a moire pattern. To avoid the moire pattern, there is a softening filter ...

Pentax woes, tell us about yours.
That's two threads on problems started this afternoon. Must be the foggy dullwaether keeping us in and away from clicking pics! I've returned to Pentax in the digital era with the KX and now the KR, both brilliant. Dust in the Pentamirror was both my fault and my only issue with the KX. Dust on t...

Pentax woes, tell us about yours.
My first DSLR was a K20D. It showed vertical banding problems and the rather unhelpful retailer (a Pro Centre) inisited on sending it to Pentax for repair. It came back with the same problem, so sent it back a second time. It came back with the same problem, so sent it back a third time. The sens...

Pentax woes, tell us about yours.
I had a sensor stain on the K5- it took me 2 months to notice it. It wasnt the end of the world, I took the faulty K5 to Rome and got some good pictures- then I had it replaced when I got back no questions asked. I agree with those who say it isnt about the problem but how it is dealt with. Ju...

Pentax woes, tell us about yours.
I think Pentax, not Sony, are ultimately responsible for the QC of Pentax cameras, in fact I don't think it's so much the sensor as the AA filter assembly. But I agree perhaps the stain issue has sensitized k5 owners to further niggling faults which they might previously have forgiven Pentax for...

Pentax woes, tell us about yours.
I have a K-5, a K-x and a K-m and have had no issues at all with any of them, apart from the K-x needed a hacked autofocus adjustment of +230!!! Yes, it was that far out on autofocus, whereas the K-5 and K-m are absolutely spot-on. K-5 level is accurate, no lock-ups, no staining, nothing wrong a...

Pentax got robbed by Fuji!
Yes, I just read the review in AP this morning! It looks like Samsung have finally ditched that 14MP sensor (pretty much the same one they used in the K20D as far as I can tell - talk about resting on your laurels!) The review said that the DR seemed on par with the D7000, so it looks like they have...

Ricoh buyout
You can thank Sony and their excellent sensor for that! Hoya put a lot of energy into cost reducing initiatives but apart from that, I seriously think they did the absolute least they had to do if they wanted to keep Pentax floating. But that's another story, and I am happy that Ricoh have taken...

Is Ricoh Pentax's last chance?
I wonder if the problems at Sony might be contributing, perhaps they need to source the sensor elsewhere... (New Samsung 20mp sensor perhaps? It looks pretty good!) That and the Ricoh rebranding exercise.

Is Ricoh Pentax's last chance?
I thought it was Kodak dumping their sensor division that was the big problem for Ricoh. My money would be on them sticking with Sony given their superb low noise performance.
