I just uploaded photos I just took of the twelve 50mm lenses of mine that I will be testing. There's one more 50mm lens that I just purchased that's on the way to me and it should arrive tomorrow.

When DCShooters' lenses arrive, I will take photos of them too, and will add those photos to our "lens gallery".
I have assigned a number to each lens. All of the test photos that I post to Flickr will only be identified by their lens number. That way, when you are reviewing the test results, you will not be influenced or prejudiced by the lens' name (e.g. Zeiss vs Pentax vs Voigtlander, etc.).

I just noticed something with my K1 that I've never seen on any other brand of camera that I've ever used. A unique, original, new, little feature that none of the Pentax APS-C cameras had, nor do Nikon, Canon or Fuji cameras.
The unique little feature that I'm referring to is a body cap that locks in place onto the camera when installed. To remove it one needs to press the lens release button. While seemingly a petty feature, I think it's a great idea. In the past, I've had body caps (especially the generic ones) work loose and fall off. This neat little feature will certainly help to keep the K1 sensor clean.
Thanks Pentax, you do the little things right!
