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.
If you planning to use your Maxxum camera with a lens which does not have electronic connection to the camera, microscope or telescope adapter, you must switch off this function. Follow the steps below to switch off the safety feature.
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.

Discussions on the MML have indicated that exposure adjustments may be needed when using certain manual focus lenses on AF bodies.
Additions 22 Aug 2003 from Peter Blaise Monahon via Minolta Mailing List
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 fifted (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
XTsi/HTsi Plus/HTsi = Press and hold the Selftimer-Drive Mode button and Spot/AE button while sliding the Main Switch to ON. (OFF appears in LCD panel)
STsi/404si = Move the function Dial to Multiple Exposure. Press and hold the Program Reset and Selftimer-Drive Mode button while sliding the Main Switch to ON. (OFF appears in LCD panel)
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.
On other Minolta AF camera models (not listed above), press and hold the following buttons, while turning the main switch to ON:
Minolta 3L camera = press and hold SUBJECT PROG and DRIVE while turning the main switch to ON
Minolta 404si camera = P and SELF TIMER (with Function Dial at ME position)
Minolta 303si camera = MODE and SELF TIMER
Minolta RD-175 camera = SELFTIMER and AV
Vectis APS cameras (adapter needed to use Minolta A mount lenses): Minolta RD-3000 DRIVE and SPOT (while switching to REC)
On the Vectis models, press the following buttons. There is no need to 'press and hold'
Vectis S-1 MODE + SELF TIMER = 'on' appears on display; SEL = 'off appears on display. Press any other button to confirm.
Vectis S-100 SUBJECT PROGRAM and = 'on' on display. +/- = 'off' on display. Press any other button to confirm.
To re-instate the shutter lock, repeat the some procedure.
This probably isn't as valid since Minolta have had high quality AF SLR's for 10 + years.
Subject: RE: 700si-MD adapter-Popular Photography June'94 >From Jarvis: In this issue on page 52, it is stated that "You can use non-Maxxum mount lenses..... you can use many Minolta MD lenses and other makes with proper non-Minolta adapters...." If you have tried to use a MD lens on your 700si or 7000, what was your experience? What adapter did you use? Is the image quality degrade sufficiently by the adapter? Why does the article say many Minolta MD lenses instead ofall? ANSWER I have used the adapter on my 7xi with MC W-Rokkor 35mm f/1.8, MD 24-35 zoom, and Tamron 90mm f/2.5 Macro, with the MD adapter. I am very pleased with the results. It is well worth the money, if you some old MC and MD lenses you want to keep and yet take advantage of the new metering systems, auto bracketing, etc, etc. I highly recommend it. I don't know why the author wrote "many MD lenses." I don't know what the restrictions are. I would have assumed all MD lenses would work. Someone else will have to answer that question. Regards. The adapter is a Soligor 7000/9000 + MD. There is no other marking. Yes, there is a minute optic but I see no differences in focal length so it is not a teleconverter. The Tamron adapter is simply the Maxxum adapter for Tamron lenses.
>>Phil Bradon at Minolta USA uses a Kenko, which has been indicated is >>available from B&H, as I recall. It is a 25mm tube. There also is a >>set for the original Maxxum and "i" series cameras, and I believe one >>was 8mm and another was 13mm. They don't, however, AF. > >I don't expect any extension tube to AF, especially when dealing with >macrophotography. I'll talk to B&H and see what I can come up with. >Thanks. On the bright side, extension tubes are available. They are made in Japan by "Kenko". Apparently there are two made, one (non-AF) set for the original and "i" series Maxxums, that will give 1x capability to a standard 50mm lens. The other supports AF, for the "xi" and "si" series. This tube is 25mm long. Mr. Bradon notes that he uses one of the 25mm tubes, and that they are stackable. It is NOT recommended that the "i" series tube be used on the "xi" or "si" bodies, as the bodies could be damaged. - Dennis > I look in the Adorama's catalog, I don't see any extention tube for > Minolta AF camera. > So what what type of extention tube do you use ? Can you still do > AF and the metering still work ? > B&H I was told by the folks at Minolta carry the "Kenko" AF extension tube for the Maxxum. It is labeled for the "xi", but should be useable on the earlier Maxxums as well. It is 25mm long. Kenko also makes a set of non-AF extension tubes. The folks at Minolta expressly said NOT to use it on the "xi" and later series cameras, as it could damage the camera. This set is shorter than the AF version. Both sets are stackable.

Here's some extra information on the adaptor SRB make (August 2001):
The Manual Focus lens to Auto Focus camera adapter works, but DON'T expect anything special. Your Manual Focus lenses will also be manual stop-down metering - be prepared for a DARK viewfinder, an unusually uncomfortable experience for an otherwise wonderfully bright viewfinder camera!!!.
And the thick adapter has a magnifying element in it to allow the lens to focus on the deeper film plane of the Minolta Auto Focus cameras, so it's like a teleconverter resulting in ~1.6x their focal length, so my lovely 16mm f/3.5 became a mediocre 26mm f/5 - OUCH!!! (Plus the additional light grabbing and light dispersing and contrast/detail/sharpening losses of the additional glass between the lens and the film!).
Finally, almost all Minolta Auto Focus cameras require resetting their programming so they will operate without an Auto Focus lens attached - usually a double button on/off setting easily performed on the outside of the camera body in the field.
The meaning of each pin is : Back of the camera Front of the camera o o o C F S C for Common F for Focus S for Shutter release. The way to activate focus is to connect C and F, and for the release, C and S. But there is still a problem : The question of the switch is not so trivial : The Minolta remote cord allow, on the same switch, to focus, and if pushed a bit more, to release the shutter. And to lock the switch with shutter released for long pause. It's possible to implement this with 2 switches, but what appens if the focus switch is held when the release switch is pushed ? Or if the focus switch is held while the shutter is released in pause mode ? I don't want to try this sort of experimentation on my camera. Scott, did you find a switch with all these functions ? or do you have 2 switches ? Anyway, for the connector, I had another solution from the news : It's to buy the cord which connect the camera to the IC R1 infrared remote device. The only problem is that this device only deal with the shutter release and I'm afraid that this cord only have two pins connected.November 2002, Csaba JOZSA adds:
The question was asked, Did I find a switch like Minolta uses, or did I use 2 switches.
The answer: I used 2 switches in the following way:
A push-on, push-off single pole, single throw switch enables focus. A momentary single pole, double throw switch de- activates focus and activates the shutter with one push.
(Pins are drawn in F C S incorrect order | | | for ease of |--/--| | | drawing -- (foc) |SPST | ___| C F S is the |--------|_|_| correct order) SPDT (shutter)Please forgive the crude drawing. Wired this way, using autofocus mode, you can first press the focus button to enable the autofocus. Then, when the camera has focused, press the shutter release button (the SPDT button) to switch instantly from "focus" to "fire" (and back again if you use the momentary switch). If you are manually focusing, you need not first press the focus button, and the shutter will still trip when you press the shutter release. If you do first press the focus button and the camera is in manual focus mode, nothing happens because autofocus is not on.
In a way, I like a 2 button setup better than a 1 button setup, because there is less chance of accidently firing off a shot. The only thing this doesn't have is a locking feature to lock the shutter open, but it shouldn't be hard to come up with a mechanical method of locking the button down.
As far as experimenting with this and the possibility of damaging the camera, as long as you don't introduce any current into the circuit there won't be a problem. The only other damage you could do is bending or breaking a pin in the camera socket if you make a connector that doesn't fit well and try to force it.
(Using an audio cable for the internal connection of CD-ROM drives...)
First cut che cd-rom connctor on the cd-rom side, to have a 20-30cm wire for the RC: on this side you'll mount the button or the switch (or both). On the audio card side you'll find a 4 pin plastic connector made like this:
1 2 3 4 r - w swhere r=red, -=none, w=white, s=shield (colours don't matter, but it's just to number the pins).
You'll work to obtain:
1 2 3 r - wWith a very little scewdriver push a little thin strip that holds the metal shield contact in the plastic connector: this way the metal contact should slip off the connector. Now you can cut the shield wire where it joins red and white ones.
Your next step is to file down the plastic connector to make it fit the camera hole. First of all you can cut away the old shield contact with a sharp knife (I don't know the English for the knife I mean), then use a file or sandpaper to reduce the size of the connector; I started with a grindstone, but be VERY careful: if you exaggerate you'll have to start over with a new connector. Here there is little to say: file a bit and try whether it fits; then file another bit. You'll have to file a lot on the long side that holds the thin strips of the metal contacts. You'll also pay attention to a little notch in the camera hole: try to file the connector to fit it.
Once you have the connector, I suggest you to strengthen the wires (red and white) that come from it: I used a glue gun (I hope the English is correct here) to create a "shell" for the wires.
Nothing more. This RC works properly on my 700si, even as a bulb switch.

(For use with Dynax/Maxxum 5000i/7000i/8000i) This Creative Expansion Card uses a special exposure program to provide the appropriate depth of field for portraits. The program automatically adjusts the aperture and shutter speed so that the subject stands out from the background.
[ info on loading card in to camera and turning it on deleted ]
To take pictures, aim the camera at the subject and press the shutter-release button. Exposure will be adjusted automatically to provide the appropriate depth of field for the subject distance and the focal length of the lens in use.
