Uh, as a matter of FACT, I attached my Canon 70-200 USM L to my Sony A7 with an adaptor and it worked just fine. IS was fine, focus was slow, image quality was, as usual, outstanding. I don't know about other lenses, that's the only real time experience I have had with the "issue", but it is not a falacy that many good lenses can be used on the Sony....that one at least....don't know about any of the others.

There are people on this bulletin board who would rather insult others than carry on a civil conversation. I suggest you ignore them... they are just trolling for responses anyhow.

It is also true that:
1. new users do not also understand that this "manualizes" any otherwise auto-lens they have
2. It changes the true distance from the first lens element to the sensor, thus- changing the focal length of the lens
3.There is an additional cost for a high quality adapter which may/may not allow for automation of exposure/shutter speed . These CAN cost as much or more than another lens. Not talking about that obscure the facts.
4. some, if not many of the adapters are of poor quality. Ill fitting - and light leakage has been a re-occuring theme with some of these. Only the best quality ones should be considered in order to avoid multiplying the "woes" .
5. We have created a false sense of reality when this is not objectively woven into the discussion.
6. This is not an anti-Canon rant. Weight is only ONE aspect of the big picture - which as a photographer your should consider as part of your "vision", and photographic philosophy. :thumbup:

It would be harder to ignore YOU - if you would truly try to add to the QUALITY of a discussion, rather than act as if a Sony was the ONLY brand of camera. In most circles, this labels you as a fanboy - nothing more. A fanboy, is not considered a credible, object resource for information - because he is blinded by his love of only one brand name. The consideration of many choices of brands, features and uses for gear separates a fanboy from a real camera guy.
Try that sometime....

Actually got a really good one (adaptor) for $70. The "metabone" is expensive but the $70 one, I don't remember the brand name, was very good, no leaks, no "wiggles"and worked great with my huge USM 70-200 lens. Again, I only have experience with the Sony so can't speak for any other set-up.

You really don't know what you're talking about.
1. Every website that sells manual adapters and every users group that discusses them states they're manual.
2. The adapters provide the EXACT SAME DISTANCE to the sensor as if it were mounted on a film camera.
3 LAEA4 adapter price has dropped almost $100 on some sites, and my most expensive fotodiox adapter was $87.
I had to mortgage the house.
4. Buy reputable, like Fotodiox.
5 You're doing your best to spread that false reality, and insinuating others are liars while spreading falsehoods does nothing to help your case.
6. Why choosing a camera is so subjective, and why I will never trash anyones choice of what they prefer.

^^^You get an "A" for trying, but I'm willing to bet you will be insulted for your effort. :(

The downside of living in this day and age is there are people who use the Internet as an excuse for behaving like children. It really is best just to ignore them... :(

Something about someone quoting my posts and basically calling me a liar that i find annoying.
And its been a week since someone told me to"stfu!!!"👏

CHOLLY Loc: THE FLORIDA PANHANDLE!

^^^Not only was I called a liar, but the person in question LIED about my views and posts.

As much as I would like to respond to them though, I refuse to give them the pleasure. My life is pretty good without letting petty, ignorant, immature people drag me down to their level.

This bulletin board in general and forum in particular is about sharing ideas and experiences relating to photography. It's SAD that people can't do that in peace. :(

That is absolutely true, and true of every camera choice. I know of people who think that the Canon SL1 is too small and others who think that other DSLR cameras are too big. So?

In my particular case, I chose "none of the above" - I went from Canon, not to Sony, but to Pentax. For forty years, I have had two cameras, one my primary camera, and one my pocket camera. By buying a Pentax Q-7, I could mount their "standard prime" lens to make it my pocket camera, or mount an adapted telephoto lens to provide the best birding camera I've ever had. That was a personal choice. Your Mileage May Vary, and the choice I made doesn't affect anyone else, so I'm not sure why this thread has become so noisy.

The adapters I am aware of insert space in the light path, to give exactly the same light path the lens would have if it were mounted on the camera it was originally designed for, but otherwise leave the light path unchanged. I don't see how that could possibly affect Image Quality. In my particular case, the adapted lenses provide a lower quality, but that is only because I am using the lenses with a smaller sensor than they were designed for. I was going to characterize this as a tradeoff I am more than willing to make - to give me an image of an animal I can actually see detail on - but since there aren't many 1400mm lenses around, I'm not really making a tradeoff. For my application, the alternative would be to buy a much more expensive camera with many more pixels, and then crop the resulting image. In each case, I end up with less detail than I would get with a 1400mm lens for the more expensive camera, but that isn't actually a reasonable alternative, so the whole IQ issue is not actually relevant in my application either.

If you know of a particular person who got reduced IQ by using an adapted lens on an MILC, then please provide the details here. Otherwise, your words give the appearance of someone who doesn't actually have experience or knowledge of the subject, because your words conflict with what the rest of us have actually experienced.

I was a Canon digital user from 2004 until 2013 when I started switching to Sony. I owned 20D, 1DSII and the 5DIII. I started with the Sony RX1. I have used the A7r for the last year or so and just purchased the A7rII. The Metabones III adaptor worked OK with the A7r but was slow to focus. The Metabones IV works very well with the Canon f4 24-105L, 16-34f2.8L,and the f4 70-200IS L on the A7rII. The macro 100 f2.8 does not autofocus with the Metabones. When using the Metabones adaptor do not have image stabilization turned on in both the camera and the lens. Use one or the other. I am now a 100% Sony user and am very pleased with IQ of my Canon lenses. The canon lenses focus quickly and the image stabilization is excellent.

^^^Yet another satisfied customer. :thumbup:

People who use Sony cameras usually love them. :mrgreen:
