Nikon -> to Canon -> to A7s?

<p>Hi there, <br /> <br /> I'm curious if something like this may work or it's just a stupid idea. <br /> I've Nikkor lenses and I'm already using them on EOS camera with adapters like these: <a href="http://amzn.com/B001G4QXLE" rel="nofollow" target="_blank">http://amzn.com/B001G4QXLE</a> <br /> They work just fine. <br /> <br /> Now I'm wondering if I could use the same lenses on a Sony A7s using an EOS to Sony adapter, something like this: <a href="http://amzn.com/B003Y302CG" rel="nofollow" target="_blank">http://amzn.com/B003Y302CG</a> <br /> <br /> Why? Because this way I could simply buy one adapter only (EOS to E-mount) and use all my (adapted) EOS lenses (Nikon, M42, OM and so forth...) <br /> <br /> Do you think this would work? (I *really* hope it can work!)</p>

<p>Sorry, Marco, The adapters shown won't work. The concept is correct however but your Canon FD-to-Sony adapter is wrong. Your Canon EOS lenses can't use that adapter. That is for older Canon FD lenses. However there are several types of Canon EOS-to-Sony adapters available. One type is the plain tube configuration that will mount the EOS lens to the Sony body but only manual focus is used. These are less expensive than the next type. There are available EOS-to-Sony adapters that not only will mount the lens but still provide auto focus, IS and aperture control. These cost more but work better. The AF is not as snappy as on Canon bodies but it does work.</p>

<p>You really don't want to rely on adapted lenses as your main lenses anyway unless every photo you take is on a tripod with careful manual focusing.</p>

<p>That Nikon to Canon adapter is a simple metal adapter - two mount rings and a spacer, no electronics. If you add it to an EOS to E mount adapter that's also just simple mount-to-mount like <a href="http://smile.amazon.com/Fotodiox-Adapter-E-Mount-Camera-NEX-5N/dp/B003Y302CQ/ref=sr_1_2?ie=UTF8&qid=1412692101&sr=8-2&keywords=eos+to+nex">this one</a> you can put the Nikon lens on the Sony.</p>

<p>My concern would be that any looseness of the adapters would be compounded by using to of them. These things are so cheap, I don't see why you wouldn't just get a straight Nikon to E mount adapter for the Nikon lenses to the Sony. You can even get a G lens compatible one to control the aperture if you have Nikon lenses without aperture rings.</p>

If you balk at the $90 b&h wants to charge for some of

these adapters try Deal Extreme. It's not like quality

is a worry on something this simple with no optical

effect. My FD/EF-M works fine even if the lenses end up

upside down. ( maybe there's some set screws I haven't

tried because I don't want to disable the mount).

<p><strong>Peter Hamm: </strong>How did we ever get pictures in focus before AF? Manual focus works very well on MILCs, especially with focus peaking. Below is 100% crop.</p><div></div>

<p>why not just get a used D3s?</p>

<p>My suggestion is just stay with a single adapter - it is better to get a cheap (Chinese) one than stack adapters in my experience. I would also stay with MF lenses and not worry about trying to adapt electronic lenses like EOS. In my experience they never really communicate with the camera well so aperture setting can be tricky (or impossible). </p>

<p>Marco, if you had linked the correct adapter (the FD mount is the predecessor to the EOS mount), as Louis states, will theoretically hope as you work, as these adapters are merely chunks of metal that move the lens to the correct distance from the sensor. You can even accomplish this through "free-lensing," which is using objects like paper towel rolls to block the light and use your hand to achieve focus. However, I'd follow Philip's advice and just get a single adapter. They are cheap enough for a quality one, and in the real world with manufacturing tolerances, you are just asking for trouble by making the adapter more complicated than it needs to be. You can introduce problems such as the lens not being parallel to the sensor. So, basically what Andy said.</p>

<p>Peter, I highly disagree with your assessment of manual focus as primary lens. So do some large format shooters (ever heard of a crown graphic?), most medium format shooters, a pretty large percentage of mirrorless buyers, most people in Leica-land, everyone that buys the Zeiss or Schneider lenses for their full frame Nikons and Canons, entire forums such as manualfocus and mflenses, etc. Go watch any number of Youtube videos or read any number of forum or Flickr posts about people using these legacy lenses handheld. I do it all the time with older Nikon lenses.<br>

Eric, the question of why not to buy a used $3,000 camera is answered by . . . well, the D3s is a $3,000! Which is best-case scenario, because I would argue that most D3s' bought were bought for professional use, which means gear abuse. Banged around, high shutter count, the works. Plus, the D3s doesn't have live view composition, which means that you lose out on the viewfinder when really needing to nail focus. You also lose out on focus peaking, which is a big deal with manual focus lenses. Plus, some of the lenses may be non-Ai, meaning that they will damage the D3s. The A7s is a far superior camera with regards to manual-focus lens functionality. Asking someone to "just" unnecessarily buy a $3,000 camera is some of the worst advice I've seen in a long time.</p>

<p>"You really don't want to rely on adapted lenses as your main lenses"<br>

<br>

I agree with Peter - I would not want a MF lens to my my main lens.<br>

<br>

When I first started using an Olympus M43 camera (EPL1), I bought a Nikon adapter. I don't know that I have ever used it other than testing it out.</p>

 

<p>Elliot, I have one too which I use with the only Nikkor I kept, a 55mm micro f3.5.</p>

<p>It works AMAZING for close-up work. and I already had the lens, and it was cheap, and I knew that whenever I shoot with that lens, I'm always manual everything anyway.</p>

<p>Other than that, no go. you're right.</p>
