I guess I was wrong. Even though the Sigma site says the lens is not available in Pentax mount the Sigma 105mm f/2.8 EX DG OS HSM Macro Lens for Pentax is listed at Adorama.com. -...

Hi Bob, Sorry but it won't fit. The front element of the Sigma 2X will hit the rear element of the A*300/4 lens. I recommend instead, the Tamron or Kenko 2X MC7...

Hi Sharon, I apprecaite that you have confidence in me. :-) I love the ouput of the K-5 + DA*300/4 + Pentax-F 1.7X AF Adapter. However, if I am going to shoot at birds in flight I will...

It looks like the K-5 is the last Pentax that has been added to the base at CameraShutterCount. Ron -- Ron - 'We don't have time to go take pics this afternoon Carl.' Carl - 'What do you...

Hi folks, If you don't want to download the popular program PhotoMe - http://www.photome.de/ to check your shutter count, then you can use the following to upload an image to check your...

The shutter of the K20D is rated at 100,000 actuations. So, the one you are talking has only used 25% of that. If you take 1000 images per month then you have 75 months (6 years) left in that...

That's a pretty fair price for the K20D. Since the K20D is weather resistant (WR) I suggest that you get a Pentax 18-55mm WR lens to go with it. If you are int the USA then this is the one that...

Thanks for remnding me to try my 77mm CPl on other lenses. I also needed to buy a 67mm CPL and a 58mm CPL. So, of course I bought the Marumi Supers. I just placed my order at Amazon.com....

To each his own choice. I have never had any SanDisk SD or SDHC card fail me in nine years of using them. Cheers. Ron -- Ron - 'We don't have time to go take pics this afternoon...

Nice capture. I wish I had moose to shoot at around here. I have only had one chance before. A mother and baby. I was trying to get a shot of the baby but no luck. I shot the momma but lost the...

Hi folks, I had read some good things about the Marumi DHG Super Circular Polarizer Filters so I bought one that is 95mm to try out on my Sigma 50-500mm F/4.5-6.3 APO DG OS HSM Lens for...

Here I am talking about generally shooting at birds in flight in the open. If you can keep the "spot" on the bird then spot is just fine. However, if you lose the "spot" on the bird then the...

Nice images Perry. It's good to be able to take the Q along with you all the time. I just ordered a PENTAX C MOUNT 6MM F1.2 to try on my Q. I guess that would be like a 33mm equivilent. I...

On the K-5 when using MUP you press once to raise and lock the mirror then within 1 minute press a second time to take the image. You can also use IR MUP. Press the IR once to raise and lock the...
