"no lens attached"... TWICE! Please help!
« on: June 11, 2005, 04:14:55 AM »
Hi there,

I am wondering if anyone else has had the same problem, since I have now had it twice, with 2 different D7 bodies and lenses.  After fully setting up my D7 (charged battery, memory card, etc), I attached the Mintola AF 28-100 lens, turned the camera on, and pressed the shutter.  However, nothing happened and the error message "no lens attached" appeared.  After calling the store and Minolta, they told me it was a defect and the camera was exchanged the next day.  We tried the "bad" lens on a new body and determined that it was the body.  
The second D7 worked ok... I think it might have a problem with the antishake?? but it did work for a good 2 months... aprox 500 shots.  It was off for about a week, and then there it was again the next time I turned it on.... the "no lens attached" error.  After going thru the custom menu and turning off the shutter lock, I am not getting the error message, but the auto focus doesn't work.  With the shutter lock on, nothing works!!  

Please respond if you have had a similiar problem, or no problems at all!  I am a little wary since this is now the 2nd camera that has had this problem.  I am getting it ready to go back to Minolta, and very worried about it's reliability on my upcoming vacation.

thanks!!!!

I've had this a few times with mine as well, seems to be poor or dirty contacts between lens and camera body. I just give the lens a litttle twist back and it comes right immediately. Shop who sold me another lens advised not to push the lens release button when you twisted the lens into the body, tended to go past the optimum contact point when I turned fully home. I was doing this just to be gentle with the whole thing.

I'd suggest giving the lens a small rotational wiggle next time, see what happens. I'd normally put de-oxit ( contact cleaner ) on for this sort of problem but very cagey about using it inside the camera.  Alcohol clean the contacts, lens and body maybe .. ?

Same here with the Minolta 28-100 that came with my Dynax 5. Just re-seat it and its fine.

It might just be that it's the lens that is bad, not the camera bodies. It's probably just a bad connection. If the contacts look clean, something worse is wrong.  Might be that it didn't work at all with the first body, and barely (for a while) with the second. Have you tried other lenses on the same camera body?

Sounds to me like dirty contacts on the lens, have you tried any other lenses? To be honest the 28-100mm isn?t the best lens made by Minolta if you get a chance and can afford it look at the 24-105mm it is a much better lens in the same zoom range.  :D

Thanks for all the great feedback!  and please keep it coming!  Just to clarify though, the current non-working lens is the second... When I exhanged the first body, I also exchanged that lens.  
thanks again!

I am not exactly sure what firmware is... I have whatever came with the camera.  I have not updated it.  Although in looking at the new version, it did not say anything about fixing this particular error. :-(
thanks!

firmware is basically the code which powers the camera. if you have the standard version that came with teh camera then maybe the latest version might go some way to helping your problems.

Not having the camera myself I cannot say for sure though.

Have you emailed/contacted Minolta about this issue?

Hmm... well I've had my 7D 'lose' the lens for just a millisecond, which then means the focus is suddenly reset to infinity, how very annoying :o
This rare occurance only seems happen with my 50mm macro and the 24-105mm and only when I change iso or wb, maybe it's just my camera, or those lenses, or the contacts?

But in reality it still works fine 99.99% of the time and I've no intention of sending it off to KM UK.
