can a-mount lens work full frame on an a7rii camera

Recommended Posts

Advertisement (gone after registration)

I purchased a la-ea3 adapter to use on my newly purchased a7rii camera to use my existing old minolta lenses.

looking at the a-mount lens charts , I see no a-mount lenses listed that will work full frame on the a7rii camera.

the chart says the angle of view will be treated as aps-c and auto-cropped.

Is this correct, or are there any old a-mount or screw-mount lenses that will perform full frame using some type of

adapter on the a7rii camera?

Almost all Minolta A-Mount lenses were full frame. The only ones that are APS-C are marked DT and are:

- 18-70 DT

-18-200 DT

- 11-18 DT


Same DT marking would apply to Sony lenses that were APS-C but the list would be a little longer


There would be a limitation if one used LA-EA1 or LA-EA2 with these FF lenses


What chart are you referring to ?

ILCE-6300 – support.dimaging.sony.co.jp

This the the place my fumbling around for research on lenses for the alpha a7rii sent me to.

It list a lot of different older lenses and indicates if they will appear in full frame or aps-c.

I was assuming it was correct about most of the older a-mount lenses, but I hope you guys are

correct, as I have also ordered adapters for canon and pentax lenses as well..    thanks for the

prompt answer to my inqiry, as I don't really know yet how to navigate thru this forum.

If you select ILCE7RMII, the lenses that do not indicate full frame are the ones that have DT in their model designation like i mentioned.

The Minolta A-Mount lenses were almost all full frame except for the 3 i listed in my previous post. Sony had a better selection of DT lenses since they were developing the line but these also have DT in their model names.

So in that page , if you only look for the ones with a small square that says full frame. You will notice almost all Minolta lenses do not mention this ( i don't understand why) but they do and many have a clone in the Sony that are mentioned full frame ( 16 Fisheye, 20mm, 28mm F 2.8, 50mm F 1.4, 300mm F 2.8, 500F8 RF, 50 and 100mm Macro lenses)

Sony probably does not want to over-promote the older lenses !!!

l clicked on the detailed explanation on each of the lenses on the chart, and the only ones that are not treated as aps-c are the ones that have a check mark on them, and the only ones like that are prefix SEL.  All the other prefixes regardless of conditions, are

treated as aps-c (according to the notations in the detailed list of specifications for that lens).

SEL prefix is E-Mount so there would be no need for LA-EA adapter of any kind


Take it from someone who owns over 60 A-Mount lenses from Minolta and Sony + numerous E-mount bodies and lenses + LA-EA1, EA2, EA3, EA4 adapters (right, i have all models right now):

Any A-Mount lens that does not mention DT in its designation, is full frame and remains full frame when used with LA-EA3 an LA-EA4 on a full frame E-Mount body

Some very rare lenses like the Minolta 3X-1X macro is incompatible with the LA-adapters. Same applies to APO lenses with the APO teleconverters.


ALL others will work in full frame with your LA-EA3 and A7Rii but with screw-driven lenses (non-SSM or SAM which is the vast majority of the lenses made by Minolta and Sony) you will only get them to work in Manual focus. To get AF with these you need to use LA-EA4.

I understand, and was only going by what the Sony chart said. I appreciate the good news from

someone who has actually experienced the old a-mount minolta lenses on the a7rii. It is re-assuring

to me to find my old lenses will work using all 42 megapixels.  (I will probably end up having to get

a larger hard drive for storage.)  I was already resloved to using them in manual mode.

thanks, again for your input..

      This is a Sony A6300 with Sigma AF 24-105mm f/4 DG HSM Art Minolta A with Sony LA-EA3 A-Mount Adapter. As well as Blackmagic Production Camera 4K EF with Sigma AF 18-35mm f/1.8 DC HSM Art Canon EF-S and Canon EF 85mm f/1.8 USM. The result is 10 minutes of peace and clouds. Except for the opening plan in the timelapse, everything else was in real time. After the post-production, it was accelerated.

      Does anyone know why Sony (or 3rd parties) can't make a better adapter for their A-mount SSM and SAM lenses? For example, the relatively inexpensive Sony 28-75 f2.8 is a really good lens. I've tried several copies and they make sharp, contrasty images. However, the AF on my E-mount bodies (a9 & a6500) is hampered by the paucity of focus points. The limiting factor is obviously not the bodies, and I don't think it's the lenses. It seems to be the adapter!

      Recently purchased this lens for my a6300 (KEH 130).  It is an unusual A mount because it is a telephoto with optic stabilization--recent Sigma lenses for A mount don't have it.  The lens is noisier than the HSM lenses but appears to focus quickly and accurately--probably not as fast as the Sony FE 70-300 which costs $1000 more.
      Went down to our harbor (Bellingham) and took some BIF pictures)  With a sky background the lens had no difficulty.  Against a busier background it had some problems finding the bird.
      Off to Alaska next week will test the lens further.
      Here are a couple of my successful images.

      I am using a rented a7R II and SAL70400 with the adapter from A to E. 
      On the a7R II it works pretty well but does not support DMF focus mode. I can live with that but not very happily.
      Today I tried the lens + adapter on my a6000 and it tried to autofocus but really could not do it. I tried both full auto and limited auto and it simply hunted.
      Since I had never read about that I decided to tell all of you what I experienced.
      FYI only.

      Hi! I have an A7 Mark 2 and the 28-70 kit lens. I am looking for a 2.8 zoom without having to drop $2200 for a G master 24-70. I see that with the LA-EA 3 adapter I can use Sony SAM and SSM lenses and it seems to AF pretty fast. My question is do after market lenses like Tamron 28-75 auto focus? I know lens have to have own motor that isn't screw drive and I think Tamron does? Has anyone had experience with 3rd party 28-70/75 2.8 lenses on a7MK 2 using the LA-EA3? Any help would be appreciated!

    • I bought a A7RIV a few months ago and I've gone out several times to go shoot. The first photo shoot (portraits) I had with it, the focus looked spot on in camera but wasn't in focus once I got it on the computer. I thought it might have been the lens I was renting so went out to shoot some landscape shots with one of my trusted lenses. The focus looked great in camera but off when I put it on the computer. I immediately took it back and exchanged the camera. I shot again with the newly exchange
    • Hi Gang, is there a guide somewhere to which of the older minolta lenses and sgma/tamron lenses as well, i need a long lens for birds mainly around 400mm or more and have seen loads of cheap long lenses on ebay, some are minolta some sigma etc, question is which will work ok with my A7ii dslr thanks

    • I have never done any astrophotography. It is my understanding that with the a7Riiiii raw uncompressed, the only change that happens by selecting a picture profile are the gamma settings. https://youtu.be/9GGDkf4wMWg Therefore, which picture profile, if any, is best for astrophotography? Thanks very much for your help.
    • Think it's quite up to me when to decide to move along. In my very first post I indirectly answered your question: the A6xxx line will only get a MP boost when market demand is big enough. As of yet, it is not. Your reluctance to respond to my statement about the improvement of technology between the A7R2 and A7R4 is quite the satisfaction I needed from this discussion. Thanks!
