How can avoid a "no lens attached" message when I plug my old MC lens with an adapter?

I tried a Sony Alpha camera in a shop. I could fit my old MC-rokkor lens, but could not bring the camera in full manual mode and get rid of the "no lens attached" message on the display. Before buying one, I want to be 100% sure that I can use my old lenses. Thanks for the attention!

Sony Alpha matches well with Minolta auto focus lens but not the MC or MD lens.

The "no lens attached " message is one of the signs that Sony Alpha cannot establish electrical contacts with the MC lens, even though an adapter is in place.

There have been many discussions over the internet on Minolta lenses and Sony body. The general view is that if you have auto focus Minolta lens, then it is worthwhile buying Sony body.

One chap just gave up the idea when he was told by another that after mounting the MC or MD lens on Sony body, he was " astonished at how awful it (the result) was "

To sum up, if quality is your primary concern, matching MC/MD lenses to Sony Alpha body is not a good idea because you just cannot be " 100% sure " that it works the way you want it to be.

Go to Menu - Custom menu - second screen.
The second raw will read "Shutter lock: On: no lens".
Change it to "shutter lock: Off: no lens".
This will enable shooting even if there is really no lens mounted to the camera.
Works for me with M42 adapter and 1100mm mirror lens with manual focus and fixed aperture.
I cannot tell what functions you will lose when mounting MC-Rokkor lens.

Julia,
Your 4th sentence "This will enable shooting even if there is really no lens mounted to the camera." is a misconception and does not make sense.
A camera needs a lens to take pictures, no matter what camera it is.

2. The link you provided is a forum for ' Lensbabies '. The original Lensbabies' instruction for unlocking the shutter of Sony A100 is found at this location
You will find that you need to do more than just unlocking the shutter before it works, like switching the mode dial from Auto to Manual and using the lens in stop-down mode.
For further information,take a look at Robert Paul's comments on May 02, 2007 at this site

3. As reported in the Internet, many people have used adapters to mount and take pictures with MC/MD lens on Sony A100, but this is not recommend by Sony.

Dear bukit97

Thank you for clarification but...
1. My name is not "Julia" but "Jura"

2. My 4th sentence says "shooting" and not "taking pictures". It makes perfect sense. If you follow my instructions the mirror will flip up and down and shutter will expose the sensor. The picture will not be sharp at all but I made no promises about that.

3. If you check the original Marco's question it was about getting rid of the "no lens attached" message on the display. My answer replies to that question while both of yours do not.

4. What was your point in replying to the first question and confronting me for giving the right answer???

5. How old are you anyway and don't you have better things to do?

6. Please don't reply. I don't want to get into a fruitless argument over nothing.

Regards
Jura

Thank you for the actual instructions how to make this work ! For a newbie like me I found I got a lot of jargon thrown at me but no real answer as to HOW to do this! I was given a MF Rokinon mirror lens and really wanted to try it out, but kept getting hte "lens not attached" message! THANK YOU!

I have the same problem with my Sony Alpha, but I'm using AF lenses. It's like the lens powers down intermittently, no autofocus, and no lens attached message. What the hell?

I have the similar problem - A100 intermittedly refuses to work with Tamron 17-50. Taking some pictures A100 shows an error massage "lens not attached". Sometimes it helps, if I turn the camera off and on again. In the same time the Tamron lens works perfectly on my old Minolta D5. Help is welcomed!

P.S. After writing this note I found a suggestion to clean the contacts on lens and on camera. I had done this before with microfibre tissue - no help. This time I cleaned the contacts carefully with spirit - and it worked! It's too early to jump from happiness, but during a whole day no refusals.

Jura... This helped me a ton. I take picks with a telescope. So I may be a huge lense,<12"> But it got me taking pictures

I just found out that for an a300/330, you just need to switch it to "M" Mode to override the shutter lock with a manual lens, or in my case a reversing ring.
