I have an 18-200mm zoom lens on y Maxxum 7D that has "frozen" or locked up, i.e., I can't move the zoom from the 18mm position. I've switched it to my Sony Alpha with same results. It just appears to be frozen & unmoveable from the 18mm position. Any suggestions as to what is wrong & how to fix it?
Have you dropped this lens at any point and where do you keep it when it's not being used ?Have you dropped this lens at any point and where do you keep it when it's not being used ?

This is because the aperture varies with the focal length. Note the "f/3.5-5.6" in the lens designation? This means that the maximum aperture is f/3.5 at 18mm and f/5.6 at 55mm. If you set the aperture first and then zoom, the aperture could change by as much as one-and-a-third stops. To prevent this, zoom first and then meter the exposure.
I have seen instances where people managed to get this problem fixed themselves. the zoom mechanism, it seems, is not all that complex. If you think you've got nothing to lose (there is a risk factor) just take it apart and have a look. Good luck!
Zooming is done from the lens on a DSLR, assuming you have a zoom lens on the camera. For example, if your camera came with the 18-55mm lens, you should see the numbers 18, 24, 35 and 55 on the lens barrel with a white index line next to one of the numbers. Turn the barrel to move a different number next to the index line. 18mm is wide angle, 55mm is 'zoomed in'.
That is the soung of everything, including the lens & mirrors getting locked into place. It's normal. I wore out a Maxxum (after about 9,000 pictures) and bought another.
Your Minolta QTsi Maxxum takes a Konika Minolta AF lens. These lenses work on these Konika Minolta DSLR cameras:
DYNAX 5D / Maxxum 5D
DYNAX 7D / Maxxum 7D
Hey needacamera, The range of an optical zoom lens refers to how wide angle to telephoto the lens covers. An example of a 6x optical zoom would be an 18mm-108mm lens, which covers wide angle to telephoto. An example of a 3x zoom lens would be an 18mm-54mm lens, which would provide a capability of capturing images from wide angle to normal views. To calculate the x factor of an optical zoom you would divide the largest number by the smallest number on your zoom. I hope this helps! Sincerely, Allan Go Ahead. Use Us.
The good news is that it is possible to get the camera to operate with the lens & adapter :-)
The bad news is that you'll only be able to use it in manual mode :-(
To get the camera(s) to actually fire, you will need to change some settings.
For the Maxxum 7:
Go to Custom settings (No.16) and change to 'Lock Off'.
For Maxxum 7D
Go to the settings menu (purple cog icon) and then to sub-menu 3. Change Shutter lock to Off.
With the camera set to Manual mode, you can still use the built-in meter. Half-press the shutter button and you will see a metering scale appear in the viewfinder. This will indicate whether the shutter/aperture setting you've selected will over/under-expose the image. Adjust your settings until the indicator bar is over the zero.
Hope this helps,
Matt.
PS. Even if you could somehow modify the adapter, the lens won't have the necessary electrical and mechanical coupling for the cameras to control it in an automatic mode.

Have you dropped this lens at any point and where do you keep it when it's not being used ?
