Help Please.

I shot around 100 images today and during processing noticed a pretty large spot almost in the center of some images.
Was shooting for our Fire Dep't in temp of around 28-30F for about 2 hours using various apertures, which I know can affect how much a dust spot shows up, or maybe not at all.

I haven't had any problems prior to today. Changed lenses last week and shot event just fine, then changed back to another lens just prior to today's event.

I have tried a bulb blower. In camera dust removal about a dozen times. Camera Sensor clean feature three times, all to no avail. Also tried another lens and the spot is still there.

Anyone have any ideas ? Only had K10D for 6 months.

Thanks, RG.

PS.

Have owned another DSLR without dust removal feature for over 3 years, changed lenses many times, never a problem with spots on images.

You might want look at the direct link above the copy.

I believe that is enough for me not to have to worry about the copyright police banging on my door.

Don't know about you, but I have never heard of anyone getting into trouble over copying and pasting articles on the net. It's done millions of times each day.

Pentax K20D on show at PMA 2008
Pentax K20D is coming and according to sources will be on display at the PMA 2008 show. The announcement of the 14 megapixel dslr together with the K200 is expected at january 24 2008.

The Pentax k20D has a 14 megapixel Pentax proprietary cmos sensor, 3 inch screen of the same type seen on Nikon models, live view, revamped anti shake, and it also seems a new file format in addition to the PEF, DNG and jpeg presently in the K10D. We can only assume it may be a uncompressed raw format.

The sensor itself is stirring a lot of comments at photo forums. This would be Pentax first sensor, but building a sensor demands huge resources and a foundry. Such an undertaking in secret is very doubtful and most seem to agree that the "Pentax sensor" must be a licensed 3:rd party product.

Sony does not have a 14 megapixel sensor so it may come as a surprise to some about who is working with Pentax in this regard, you will just have to wait and see

Pentax management outlined in March 2007 the direction of Pentax DSLR products and declared that consecutive models would offer true upgrades and not just reworked models (like the *ist that had numerous versions on the market)

The K20d may use the same body as the present K10d but the difference in specifications will be so big that this truly is a new model - it is not a K10d mkII. If for nothing else, just the new sensor merits a new model name.

Expect a starting price at around 1400 us$. Pentax is starting to look like a serious playter. the only backwash is the lens market that is still weaker on choice that the other brands. This has in part to do with the cooperation between Tokina and Pentax. As a direct result, some 3-party models are unfortunately not available in Pentax mount. However - it seems that the new Tamron 70 - 200 2.8 will also have pentax mount. Very good news indeed as this lens is a stellar performer - and lightweight. More on that later.

Stay tuned for more news on Pentax K20D and the K200 (that will have the 10 megapixel sensor).

Pentax. New from Japan !!!!!!!!!!!!!!!!!!!!

RG.

George,

See what I mean, those zooms are just for, your quote "taking holiday snaps" unquote. nothing serious of course, we need a prime for that.

I would very much like to see some of your prime lens shots posted along with your peasant type holiday snaps !!!!!!!!

What a crock.

SK and DB.

I had the Sony 1000 when it first came out and I can assure you I printed many great images 8X!0 and had them printed much larger and they still looked great. Have used every decent P&S and most bridge camera's with similar results.

Although I will probably never go back to it 35mm film and the darkroom, it is pure photography. One had to take much more care when shooting and developing and the best guys were pure talent. Yes you could work for National Geographic like one guy I know of, still shoots nothing but film, taking thousands of images per assignment. Try that out of your own pocket book. This guy is a rarity in todays world of pro's.

With digital one can adjust or cheat like crazy with a couple of fingers in a few minutes, not only that but many images don't even remotely look like the original. I look at some of the images winning competitions and I honestly don't know what the hell they shot, or what the judges were smoking.

That's what I mean.

Cheers, RG.

Glad you like the Tamron 18-250mm. I have it and believe it's a great lens.

Seems to me so many DSLR owners get carried away with a pot full of lenses, some also get a bit snobby when it comes to using big zooms.

Fact of the matter is most of the time one can end up with a really good image with all the available software, no matter what the lens. There is not too much one can't manipulate. DxO is a prime example, if one has a lens on their list.

I would bet most of the images posted on this forum have been adjusted in some way.

I love digital, however it is certainly not a pure form of photography.
Now we can go shoot a project, take 5000 plus images and pick out the best basic shots, adjust and bingo. We don't have to be very careful anymore, pick the right subject and fire away. For the vast majority, very unlike film, due to the cost.

So why not use one good old big zoom most of the time. Now I can kind of chuckle when I am out with just this set-up and the other guy is lugging around 500 pounds of gear, missing shot after shot sorting through his portable lens store for just the right one !!!!!!!!

Enjoy your Tamron, or the fake Pentax version.

Cheers, RG.

I have the Tamron, very happy with it.

The Tamron made Pentax is supposed to have their extra coating on the glass ?

This is a keeper for me, so not a bit worried about re-sale value, in any event I don't think there would be much difference.

The bottom line for me was price (I purchased mine for $400.00 new with a UV filter) The lowest price on the Pentax $500.00.

Buying either in Japan, I would be more concerned about the warranty and the customs duty than I would about re-sale.

Not only that, in my opinion the Tamron is a much better looking lens.
(If you are into looks)

Cheers, RG.

Don,

I believe I agreed there are some crooked cops, however given what they go through every day, they are still a minority given the thousands of cops out there doing a great job, despite the liberal mantra.

Sounds to me like you hate all cops, for whatever reason and are having a love affair with real villains. If we all listened to you, no one would ever trust a cop.

SPB.

Right on. Liberal hand wringing cool aid drinkers are an even bigger problem.

We worked very hard for what we have HONESTLY. I will be dammed if I will have some human garbage take it away from us without one hell of a fight.

Who would you rather have in your corner a weenie liberal, or someone willing to fight back ?

My last word on subject.

RG.
