Hi Pentaxian friends.
I saw this on Image Insider which I subscribe to. Take a look, it's facinating. I never knew there was so much work to put a lens together.

Only 7 days before PMA09, can you believe it? I am curious to see what new cameras will be announced at the show. According to Photography Bay, Pentax is to announce new DSLRs. I Quote" Expect some big news from Pentax at PMA. Hoya, Pentax’s parent, issued a statement with its second quarter 2008 financial results that revealed some of the things to come from Pentax in 2009, including 3 new types of DSLR cameras.

It is for that reason that I rarely install the supplied hoods on my lenses. First, they increase the length of the lens and become a hazard. Secondly, I can use my hand to block the sun rays just as good as a lens hood can.
You can also get a collapsible rubber hood with filter threads, install it like a filter, or over the filter you are using. That way, the filter and the hood will turn together.
P.S. I found a website that actually lets you download a PDF file containing some of your favorite Pentax Lens hood. You just cut it out, fold it and slide it on your lens. I would paint it flat black myself. Check it out.
I also found this ingenious person that made a good looking hood himself.


It's a pinhole, home-made lens. With a DSLR, pinhole shooting becomes as modern as can be. The results are as instantaneous as your DRLS can display it on the LCD monitor. It's really easy to make your own, although some fancy assembly can be purchased. What you need is a Pentax camera body cap, and one small piece of aluminum foil or brass shim. Drill a hole measuring about 1/2 inch in diameter in the body cap. Take the smallest needle you can find, and gently pierce a hole in the foil. Note that the smaller the hole, the better the image will be. Cut the foil so that it can easily fit inside the body cap. Tape the foil inside the body cap, making sure the small hole is located in the center. That's it, you have a pinhole lens. A flashgun in ‘full power’ manual mode can be used to illuminate a subject up to about 6”away. Two advantages of flash are; not having to worry about camera shake, and extreme contrast which adds to the apparent sharpness of the image.You want to make it a telephoto lens, simply use extendion tubes. Because the image circle gets larger as the distance between the pinhole and the sensor increases...you get an instant telephoto. The DSLR will have to be used in manual mode for the shutter speed, but the auto-focus is not necessary as the lens renders images equally focused Try it, you will have a blast.


Good references on pinhole.

that I still had a little something for her. I gave her the White K2000 and she was really surprised and really likes the camera. She often accompanies me when I go on a photo shoot and uses one of my cameras to take pictures as well. She adores the pearly white K2000 and I bet your wife would like it too. Now she has her own, and a very exclusive one at that.
She already took some pictures in Calico, an old ghost town in California, and in Pasadena with the K2000. Here are some...pretty nice aren't they?
