Downsizing a bit and selling my Pentax K10D as a kit. The camera works great. There are a couple of minor irritants. When you change batteries you have to reset the date and the focus confirmation beep does not sound. Very low shutter count of 1442 ! All the lenses have good glass with nothing more than a little dust. All the lenses come with both caps.

The camera comes with;

K10D body
3 batteries and charger
16GB SD card
Pentax-F 35-135mm lens
Vivitar 28-70mm lens
Sigma UC 70-210mm lens
Rikenon P 50mm F2

I accept Paypal

Shipping will be around $18

Sigma 18-50 mm f/2.8-4.5 vs Sigma 17-50 f/2.8

The reviews here on the Forums are much better for the Sigma 17-50mm F2.8 than the Sigma 18-50mm. I have the Sigma 17-50mm 2.8 and it is one of my most used lenses. It is very sharp and I use it for portraits in close quarters when I do not have the room to use my Pentax DA* 50-135mm. I highly recommend the Sigma 17-50mm.

Nice shot !!! I love some of the older paint schemes especially the older American and Braniff paint of the late 50's early 60's.

For Sale - Sold: Super Cosina 100-500mm F:5.6-8 lens for Pentax K Mount

Item for Sale
Super Cosina 100-500mm F:5.6-8 lens for Pentax K Mount

Asking Price
55.00 USD

Item Location
Bedford Texas (United States)

Item Description
Pentax K mount manual focus Super Cosina MC Macro100-500mm f/5.6-8 zoom lens. I believe this lens is related to the Vivitar Series 1 100-500mm f/5.6-8 (which was manufactured by Cosina). It is a tank and surprised me with the sharpness at the long end. The included pictures of a water tower were taken at 500mm, ISO 400, and F8 a quarter mile away from my house. Angel picture was taken from across the room of the Angel on top of a 12 foot Christmas tree (yes, the tree is up early this year). Cat picture was take between 100mm and 200mm. I highly recommend using the hood outside as it improves the contrast.


The glass is good but not pristine. There is a decent amount of dust on the inner element. When I shine a flashlight through the lens I do not see anything resembling fungus.
As you can see the pictures come out nice., Aperture, Focus, and zoom are operational with no issues.
Has the tripod ring, both caps, screw on hood, and lens case (not pictured).

Your picture reminds me of a funny story about the F-111. I had a 2nd level manager who flew in the Air Force for many years before moving into the Computer Business.
I had a large library of aircraft pictures I would rotate as my wallpaper. One day Bob comes by my desk when I have a picture of an F-111 with afterburners lit as my wallpaper.
Bob stops and says to me you know I flew that plane. I turned to him and said your flew F-111's ? He said yes and that plane on your screen was MY plane. He recognized the
tail number. We had a very interesting conversation that followed.

Thanks for the picture !

How many lenses do you have?

I have been as high as 22 lenses. I have my favorites for specific purposes.

Tamron SP 90mm for macro
Pentax 55-300mm PLM for birds and butterflies
Pentax DA* 50-135 for Portraits
Sigma 17-50mm for wide angle

Beyond that the fun in is in buying a lens and testing it to see if you have a gem or got a huge bargain.
My problem is every time I see a lens I have not tried before I want to acquire it.

Oh curse you LBA :eek::eek::eek:

I took my 55-300mm PLM to an air show last month and took almost 800 frames during the afternoon. Not only was the AF reliable but I brought home some nice shots. I was a bit apprehensive since I had not put it through its paces to that extent before. It was a trooper.

I have owned the Pentax 18-250mm and it is a good lens but not great. It really needs to be stopped down between F8-F11 to get good results. I am with c.a.m. on his alternatives. I also have a Sigma 17-50mm and to me it is superior to the 18-250mm. For the money there is a lot of value in the Sigma 17-50mm. I use it for portraits and the shots are always excellent.

Good luck !

I am entering this photo to honor my father who I lost on October 7th, 2019. He left me his old M42 lenses and his IST DL camera.
I took this picture with his old Sears M42 80-200mm that he owned since I was a kid.
