I am planning on selling my Canon 6D II and getting an A7III in the coming months and wanted some advice. 

 

I was considering getting the Metabones V but I rather use the native lenses (I will probably add the new Tamron 28-75mm f/2.8 once released and if it is good) so I'm thinking the MC-11 may be the better option. The reason for this is, the only lenses I plan to adapt is the 16-35 f/4L and 100L which both are used for static objects and don't require fast AF (long exposures, landscapes and still life) and would rather save money being that Metabones is twice the cost. 

 

I don't really shoot any fast paced action shots, just mostly landscapes, still life and the odd portrait. Does this plan seem logical and like a good idea?

No, I don't think it's a good idea. If you use adapters to cripple the native functions of a Sony mirrorless camera, it's just a sensor in a box. It won't perform a lot better than your 6DII.

 

Sony only used to emphasise adapters back when their lens line was inadequate. It's not actually a realistic way of doing photography.

When it comes to IQ, how would I be crippling the A7III using adapters? If I am shooting landscapes I use manual focus so AF reliability isn't as issue.

Lens adapters cause misalignment, which can affect IQ. Even if the misaligment is microscopic, it can reduce sharpness in the image. Digilloyd and Lensrentals have tested it and written about it.

I have sold essentially all of my Canon glass because native just works better.  Having said that I kept my Sigma 18-35 1.4 Canon mount with King adapter (was $80 years ago and actually out performed mc-11 and metabones III); but I don't think you can find the King available anymore.  It was/is a great adapter for $80!  The 18-35 works well, fast focus including fast eye autofocus.  As a result I sold my Metabones III, and IV...the King was just better with the lens selection and needs I had.  If you can find a King you will save $$$$.

Too many members of the forum will read

that Lensrentals has written about how ...

  

.... adapters are hugely

and totally useless .... 

     

without comprehending that it says they are 

totally useless for use on an optical bench, 

but failing to realize what that means.   

     

The adapters absolutely failed to be precise 

enuf to serve as an integral component of

an optical bench. BTW they are also totally

useless as hockey pucks. Both these facts  

are equally meaningless to photographers. 

Lensrentals does a disservice to the photo 

community by discussing optical bench use. 

   

Thaz like saying the drugs that save your 

life ... chemicals that are USP phama-pure, 

have absolutely and totally failed to be pure 

and precise enuf to be used as analytical

reagents by research chemists. BTW that is 

generally the case. That is why chemicals 

come in three grades: Reagent, USP, and 

Industrial. Do not put industrial in your body. 

But USP is for USE in your Body. Reagent 

is waaaaay too pure and precise and costly 

to waste on human consumption. It is for 

research analysts, and must be ultra perfect

so as to have no tiny trace element that will 

bring error into test reactions. Likewise an 

optical bench is a TESTING device, and so  

every element of it must be 99.999...99% 

error-free. True, adapters are not that pure.  

    

An Optical Bench is not for making actual

photographs. It's for ultra accurate testing.

IOW it needs "reagent" grade components, 

waaaaay closer to absolute perfection than 

the USP quality that you use on your body, 

IOW on your camera body. 

   

Adapters are not good for the devices that 

TEST lenses. They are quite suitable for 

devices that USE lenses to record images.  

   

This all spelled out in the linked story if you 

know how to objectively READ it.

Actually it's only the ability to adapt to such a wide variety of lens mounts that interest some of us. It's given me a wide variety of lenses to choose from for less than the cost of a single native lens. While the native lens line up has increased dramatically it still doesn't have options that match the capabilities of some of my toys. Coupled to a rangefinder lens a mirrorless camera will manage much better than a DSLR.

Sony's longest lens is 400mm, I have 500mm, 600mm & even 1000mm options even without using teleconverters. There are a couple of native tilt shift lenses from 3rd party manufacturers, but they are fully manual too so don't offer much advantage over adapting with a tilt/shift adapter...

I don't use AF when adapting lenses, but there's even an adapter that allows ANY lens to AF on later Sony bodies (the Techart Pro)

Sony may prefer us to all buy their lenses but using adapted lenses is quite realistic and far more fun.
