The SRT 101 was my FIRST real camera... and I WISH I still had MY collection of Rokkor lenses; in a word they were EXCELLENT!!!

As Ltgk20 mentions, the Sony A mount cameras... direct descendants of the original Minolta A mount cameras, have a different mount than your Rokkor MC/MC mount lenses and the two systems are incompatible.

You can find the adapter to manually focus your MC/MD mount Rokkor lens on the A99II A mount camera here:

With the A99II you have an EXCELLENT focus peaking feature in addition to focus magnification and one of the best EVF's available.

Ltgk20's suggestion that your Rokkor lenses would be a perfect match for the Sony E mount series of cameras is also a great alternative.

If you are prepared to spend the $3200 for the A99II, then you can buy the A7RII which uses the exact same sensor but produces slightly better image quality than the A99II. It is also smaller and considerably lighter than the A99II, and at this time several hundred dollars LESS expensive as Sony prepares to release the A7RIII to replace it.

The determining factor is the style of photography you intend to use the camera, and whether you want a small form factor similar to your SRT-101 or a traditional DSLR form factor that's larger.

Additionally, the A99II will shoot up to 12 frames per second, while the A7RII can "only" manage 5 fps.

You will ALSO need an adapter to use your Rokkor lenses on the E mount A7RII or any other E mount camera. There are currently 7 Full Frame E mount cameras: A7/A7II, A7S/A7SII, A7R/A7RII, and the brand new A9, which is geared towards professional sports and photo journalism.

ALL Sony interchangeable lens cameras regardless of mount offer focus peaking and focus magnification making them PERFECT for using older manual focus lenses. And as stated earlier, the image quality from Sony Cameras is EXCELLENT. Additionally, Sony cameras continue the Minolta legacy of innovation by offering a LARGE number of features and capabilities, usually for LESS than the competition.

So you DO have options to use your lenses.

GOOD LUCK!

This is all good advice. But one clarification. The older Minolta MC/MD lenses, as used on the SRT 101 cannot be adapted to be used on the A99II if you intend to be able to focus to infinity. But you can get a different kind of adapter that has a lens in it, much like a teleconverter, to overcome this problem. But now you introduce all the IQ killing properties of the teleconverters. If you use an E-mount body, any of them, there is no such restriction.

Here is an adapter with the glass: (doesn't say what the magnification factor is, but I think they are about 1.4x.

By the way, I am very, very fond of the Minolta Rokkor lenses. And I do use them on my A6xxx bodies. But I can't use them on my A-mount bodies and I am not interested in the adapter that adds the glass to make it focus to infinity.

Ha, I was about to post this link myself. https://www.youtube.com/watch?v=5TSCjUlQsjE

Once again, I will say this for the record:

1) The Sony A9 appears to be an excellent camera

2) The entire industry is in transition, no company has it right yet, and the transition will take years to play out.

3) At the end of the day it is about the entire system not just the camera.

4) This video appears to be an independent, impartial review, and in my opinion is fairly balanced. It gives some very positive assessments and also comments upon limitations.

5) We need balanced viewpoints more than we need advertisements, so people can make informed decisions for themselves.

So, to Cholly, you may call me 'Trolly' if you want to. I will call you 'Shilly' in return. Neither approach supports a useful objective discussion.

I thought this video was especially useful in praising the achievements made by Sony with the A9, pointing out the limits of the native lens availability, the benefits and limitations of the Metabones adapters - arguably some of the best adapters available - but completely supports the thesis that the market and industry is in a period of major transition and it is much too early to predict the outcome.

I have an old Minolta SRT-101 camera. I want to upgrade to a DSLR camera. I saw where the Sony a99 II camera body was advertised as accepting old Minolta lenses, but the auto focus feature on the camera will not work since these are not auto focus lenses. At the camera store I was told my old Minolta lenses will not fit the Sony a99 II body, only newer Minolta lenses will fit the Sony a99 II body. I would like to know if this is correct, or did the camera store people tell me this only so they could also sell me a new Sony lens.
