Minolta Lens Mount Check

Can I use the 3D Lens-in-a-cap on my Dynax/Maxxum body.

The Maxxum/Dynax range use a form of checking that ensures that a lens is mounted correctly. This is primarily to stop any damage to the lens or camera. To achieve this, if the signals are not read correctly between camera and lens then the shutter is locked.

This is all well and good except if you want to connect to a telescope or a lens not available in AF mount such as a perspective control lens.

How to disable the lens mount check.

Minolta added a protection feature on the Maxxum Series-xi and Series-si cameras which does not allow shutter release without an electronically attached lens. An electronically attached lens is a Maxxum or Minolta AF or other manufacturer lens with electronic contacts.

If you planning to use your Maxxum camera with a 3D Lens-in-a-cap, you must switch off this function. Follow the steps below to switch off the safety feature.  Be sure when doing all these steps to do them without a functional electronic lens attached.

Note: There is no way to switch off the safety feature with Maxxum 2xi, 3xi and SPxi cameras. Therefore, they cannot be use with other than a Maxxum AF or similar lens.

Minolta AF camera models are variously named Alpha (Japan and China), Dynax (Asia, Europe, Africa), and Maxxum (the Americas).

Minolta xi and si cameras, and most later models, have a shutter lock, which prevents the shutter from being released if anything other than an AF lens is fitted (e.g. slide copier, T-mount manual mount lens, telescope, et cetera). To over-ride this:

Minolta 35mm film SLR cameras:
Minolta 9 or 7 camera = Select Custom Function 16 and set to 2
Minolta 5 camera = Select Custom Function 14 and set to 2
Minolta 4 camera = Select Custom Function 12 and set to 2

QTsi = Press and hold the Selftimer-Drive Mode button and Subject Program button while sliding the Main Switch to ON. (OFF appears in LCD panel)

To re-instate the shutter lock, on Dynax 9, 7, 5, and 4 set Custom Function back to option 1.
