Help! bad hook.

canny891 · 09-04-2015, 07:45 AM

(sorry for my english)
Yesterday i bought Mirage lens 28MM f2.8 (k mount).
When i try to hook at my pentax k-50, It does not engage well. It snaps in half and then not go forward, it blocks.

Here are some photos:

In the last picture It looks like the Ricoh pin?? 180 from the red alignment dot. Are you sure it is a K-mount? This pin needs to be removed to use on Pentax DSLRs.
Not all that sure as i don't have any with the pin, but a google search shows that location.

If it is a Ricoh pin it looks to me like the larger rounded spring type that doesn't really need to be removed.

The pin ISNT the problem at all on this lens as the Pin only prevents the lens from being removed after it is mounted........ I have the same exact lens and mine mounts somewhat tight but not sure why yours wont ?

The baffle is the metal "shield" that looks like a shark fin beside the rectangle sticking out of the back of the lens. The rectangle operates the aperture blades. The shields of some lenses can be too large and run into things inside the open space behind the mount ring in the camera body. However another user has mentioned that they do not have any problem mounting the same lens on their camera.

The ricoh pin is a pin on some Ricoh k mount lenses that can get stuck in the screw that drives the lens focusing on autofocus lenes without an internal motor. The pin seen on this lens appears fairly rounded and is not likely a problem but could be removed to be sure that the lens doesn't get stuck ON the mount. That pin has nothing to do with not being able to mount the lens.
