That shouldn't be a problem - Sony bought minolta, and based their DSLR's off the minolta line. This lens is supposed to work with the Sony without any problems.

That lens was made for minolta cameras. and it would need to be whats called. "Re-chiped"
if you get a hold of the company that made it then they usually do it for free. If they still have parts.
So what happens is. even though it is an auto focus lens. It wasnt set up to work with sony.So you jsut need the lens and camera to speek the same language in theory.


If you took it to a camera store they should beable to help you get in contact with the company.


Hop that helps,
Caleb

    Not true. Bought one of these lenses, and it works with my Sony straight off the bat, as have every other Minolta lens I've tried. As long an it's a Minolta A mount, if it's not working, the lens is faulty.

How can I stop the metering on a Sony a77 Camera?


When you are using non brand lenses, with an adapter ring, most camera's can't communicate, so you have to use the lens as a non chip lens and it only will work in full manual mode. So switch the camera to M (manual) and then do manual focus and manual aperture on the lens. When you shoot a picture, look on the histogram if you need a faster or slower shutter speed and dial in the speed (manual) you think is correct.

I have been given a Cosina 1: 3.5-5.6, MC MACRO, 58mm lens size, 28-80mm AF lenses. Don't really want it, what should I do? a) bin it b) give it to a charity shop c) find out which camera it is for...


If it's a Cosina, then it's a Pentax KA mount lens. They're always in demand but prices will be low, even if you're certain that the lens is working. If you cannot confirm the lens works, then it's no good to a charity shop (they'd know nothing about the lens anyway unless they specialise in cameras like one in Redhill, Surrey). Throwing it away just adds to landfill so why not join your local FreeCycle/Freegle group and offer it there, clearly stating that the lens is untested? After making an offer, it opens the door to asking for things which you may sometimes want so could be a good way to start.

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.

I have a Cosina AF Macro 100mm lens that I used on


you should be able to use that lens with it. As long as it attaches to the SLR body ok. The thing to be aware of is with better technology in the newer camera you may have AF issues with that particular lens.

I have a sony alpha 100 i want to buy a 1993 minolta maxxum 3xi with 35-70 and 70-300mm lenses. Those minonolta lenses are compatible with my alpha?


I took the following off of the Alpha website
"Sony Alpha lens mount
Identical to the Minolta A-type bayonet mount, enabling the use of a large back catalogue of existing Minolta and third party lenses"

I know that the lenses that fit my son's Maxxum will not fit my non-Maxxum Minolta bodies. VERIFY THAT THE LENS YOU WANT TO MATE TO YOUR SONY HAS THE MINOLTA A-TYPE MOUNT.

You should have no problem, if they are maxuum af. The others should work too- I have an Alpha 100. The alpha 100 works great. I used to run my own photography business, and searched around for quite a while before I found the alpha. There is an adapter ring that i bought, that makes it possible for me to use my favorite old pentax screw mount 135mm f1.6, or any other screw mount, on my alpha 100.
The only drawback I found was you cannot use any other flash(at this time) than the onboard one-or the sony only flashes-which are a little pricey. Different size hot shoe is the reason. I haven't found an adapter yet-but I'm sure someone will make one. The alpha doen't have a real time display- or asa of 3200. I'm hopeing for a firmware update/upgrade to correct this. BUT the newer models with a higher than a100 number do have realtime lcd, and do go to asa3200. And they use either sony mem.stick or CF cards happy shooting

Sony A100 compatibility


It would help if you actually gave details of the lens!

All the old Minolta AF and MF lenses will fit the Sony A100, but only the AF are auto-focus compatible.

Since the Maxxum 7000 was an AF camera, I would image that that is an AF lens pictured on the front.

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

QUANTARAY FOR MINOLTA AF 70-300MM compatibility


Usually mounts are unique to a camera manufacturer. There are exceptions. Sony has the Alpha; lenses for the Konica-Minolta are the same mount. Your AF (autofocus) lens will work on it. You might also consider picking up a Konica Minolta 5D or 7D.....they're no longer made and hence are cheaply had.

The MD and Rokkor lenses won't work on the Sony Alpha.
THIS IS A CHEAP LENS (<$50 VALUE) SO I WOULDN'T LET IT DRIVE YOUR DECISIONS!!
