Finally. This is advantage number one (reference number, not most important) of screwmounting system vs K mounting system. With the screwmounting system you dont need to align anything in a specific rotational position which means in low light or the dark its faster. And even though some K mount lenses have "bumps" to help you align them in low light or the dark, its still slower and more cumbersome because you have to find the body bump too, and based on latest posts here, they have eliminated this feature in order to remove restriction of where to put the release button, so you can no longer easily mount K mount lenses in low light or dark like you can screwmount lenses to this day.
Start thinking about advantage #2 of screwmounting system vs k-mounting system. since I gave a hint on the last one, here's hint on this one : this one is opto-mechanical advantage. jco -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of William Robb Sent: Thursday, February 15, 2007 9:13 AM To: Pentax-Discuss Mail List Subject: Re: Well anybody know in what ways m42screwmountingsystemissuperior to K mounting system? ----- Original Message ----- From: "mike wilson" Subject: Re: Well anybody know in what ways m42 screwmountingsystemissuperior to K mounting system? > > Buggered up the lens release?

What's your take on the matter? > They moved the release button to lower on the body, and removed the alignment dit from the lenses (this was done on the aperture ring free lenses). Prior to this, if you put one thumb on the lens release button, and the other thumb on the did, all you had to do was line up your thumbs to mount the lens. It was possible to mount a lens without looking at the camera, and was one of the features that brought me to Pentax. M-42 was better for mounting because there was no alignment of any sort required when mounting a lens. The downside of M-42 is that lens changes took much longer because of the number of turns required to remove the lens compared to the 1/4 turn required on the K mount.
