SOURCE: Sony A100 compatible lenses

Virtually all the old Minolta lenses are compatible with the new Sony SLRs.

For the two you mention, you will need to check whether the lenses are the AF or MF versions.

Both will fit, but AF is the auto-focus one, and MF is (obviously!) manual-focus.

If you want a definitive list with tech details on ALL the Minolta / Sony lenses, look here:

SOURCE: sigma 70-300 +''no lense attached'' w/ sony a200 dslr

Unfortunately, there are electrical differences between early and later Sigma lenses. Although the bayonet connection is the same, and the lens can fit, it will not necessarily connect electrically with the connections on the camera. Sigma can modify the lens for you, but this can be quite costly, and you may be cheaper to look for an alternative lens.

SOURCE: Sony 18-70 kit lens vibrates badly

This is a lens problem, the AF motor of the lens is trying to engage the gears. Sometime it works, sometimes it does not... It happened to my sigma 70-300. The only solution is to have it repaired. If under warranty it should be free, if not.... might be cheaper to buy a new lens.

Can you use the twist-barrell zoom lens on a Sony DSLR camera (or any DSLR) when the camera is set to auto-focus? I've been told that this damages the gears in the lens if you do. Thanks for your help.


You can zoom completely independent of the focus.

Some lenses immediately override the autofocus when it senses you turning the manual focus ring. Other lenses don't, and you can damage the lens by forcing it. It depends on the lens, so you'll have to consult the documentation for the specific lens.

Can u use the lenses of minolta slr camera with any other digital camera body today and if yes then models may be suggested


If you have manual focus Minolta lenses, then they are not usable on anything other than other manual focus M35mm Minolta SLR's.

If they have the Minolta autofocus mount then they will physically fit onto any of the current range of Sony Alpha SLR's and also the discontinued Konica Minolta digital SLR's, but there will be some issues:-
  • there will be a 1.5x magnification factor due to picture cropping caused by the digital image sensor being smaller than a 35mm film frame. As an example, a 70-200mm zoom lens will produce an image equivalent to that of a 105-300mm lens if mounted on a 35mm camera. Lens apertures are not affected by the 1.5 crop factor.
  • Earlier Minolta AF lenses relied on the camera body providing the autofocus motor. Later Konica-Minolta and Sony models lack this motor so the lens can only be used in manual focus mode.
  • If you have a later SSM (SuperSonic Motor) equipped lens and want to use it on an Minolta Alpha/Maxxum/Dynax 9 (different model names in different countries), the camera needs a complete additional circuit board which is no longer available.
  • Later Sony Alpha SLR's have far greater electronic communication with the lenses used. Many Minolta lenses will not be compatible and as Sony don't support legacy products there is no fix.
In short, Minolta MD lenses (manual focus) can't practically be used on any modern digital cameras, and Minolta Alpha (autofocus) lenses will physically fit onto a Sony Alpha digital SLR, but will act as if magnified and may not autofocus or work at all on a Sony SLR. But there's no harm in trying.

Sorry there is no absolutely definitive answer for you, but I hope that you now understand why and that you take a moment to rate my reply.

Adapter ring make camera read no lens deteched


The 650-1300mm lens lacks the electronics to communicate with the camera. You'll have to focus manually, and set the camera's exposure mode to Manual.

Hi, I have got very strange noises coing out fromo


I have got the same issue. It sounds like when a motor goes past a point and can't go no further. I don't know anything about cameras and there internal workings, but when you extend the focus ring all the way our and turn the camer on, the camera will not make that noise until the focus ring is back to it's full in position....

When the camera is turned on, the lens vibrates briefly for 4 sec.It doesnt matter if its in Auto or manual focus. It happens while turning off the camera as well. I have sent the camera to the Sony...


It is likely to be an issue with the auto focus in the lens. You will get the grinding noise even if you switch the camera on in manual focus, but not if you take pictures in manual focus.

The lens kit of my Sony DSLR A200 produces noise


If it's in continuous auto-focus and doing it, then it is just not locking on to one thing and jumping back and forth between two objects that are very close together in distance and it is normal. It should stop in manual, single shot or single point auto-focus. Sony uses Nikon auto-focus technology and my D-300 with a 70-200mmf2.8 will do it if I turn the auto-focus tracking time(lock-on) all the way down with the auto-focus in full auto.

Not working with Sony Alpha 100


well after a week in the shop it came back working. the guy at the shop could only tell me that the repair people had fixed a problem in the auto focus (he had no other information). So the solution here is going to a place to repair your lens. if someone finds the cause of this problem it would be great
