russ_albion Posted September 20, 2012 Share Posted September 20, 2012 <p>Hi. I'm asking on behalf of a friend who is contemplating this purchase. Is there any need to be concerned as to compatibility between the new Tamron 24-70/2.8 and the up and coming 6D?<br><br />Thanks</p> Link to comment Share on other sites More sharing options...

esfishdoc Posted September 20, 2012 Share Posted September 20, 2012 <p>They will work well with each other...<br> Richard</p> Link to comment Share on other sites More sharing options...
Marcus Ian Posted September 20, 2012 Share Posted September 20, 2012 <p>No reason I can think of... EF compatibility is pretty universal (w/ a few old school exceptions)... Of course Canon <em>may</em> have equipped it with the new 3PLD chip, so no guarantees ;-)</p> Link to comment Share on other sites More sharing options...
russ_albion Posted September 21, 2012 Author Share Posted September 21, 2012 <p>Lol, Peter, no that's something I'm most likely to do. <br /><br />Marcus, thanks I will ask around but it doesn't make sense at this stage for these two well established companies to pull a move like that. I'm sure the much older Tamron 28-75 would also work just fine with the 6D.</p> Link to comment Share on other sites More sharing options...
ljwest Posted September 21, 2012 Share Posted September 21, 2012 <p>"Di" in Tamron-speak means that it is a full frame (35mm) lens that has been "<a href="http://www.tamron-usa.com/lenses/technology.asp#DI">Digitally Optimized</a>". So it should work on any of Canon's 6D, 5D and 1D models, as well as any EOS film camera. It'll also work on any crop camera, like the 7D, xxD series and the Rebels/Kiss/xxxD series.</p> <p>As always, when buying a third party lens, there is a small risk of incompatibility. Canon does not share their EOS specifications with third parties, so they've all (Tamron, Tokina, Sigma, etc.) had to reverse-engineer the mount and control systems to work on EOS cameras. </p> <p>But the introduction of a new camera isn't likely to be a problem.</p> Link to comment Share on other sites More sharing options...

Rumor has it that it also checks to see if the lens is a modern 'L' and 'turbo-boosts' the AF speed, and AF phase-detect accuracy... maybe that's pure internet speculation/ conspiracy mongering, but I think it MUST be true! ;-) </p> Link to comment Share on other sites More sharing options...
JDMvW Posted September 21, 2012 Share Posted September 21, 2012 <blockquote> <p>But the introduction of a new camera isn't likely to be a problem.</p> </blockquote> <p>To the contrary.<br> If there <em>were</em> to be a problem, this is precisely where it would occur -- as new features are added, the likelihood of a bug in older, reverse-engineered firmware/software is increased.<br> One would probably not suggest (unless they had a very good lawyer on retainer) that Canon would ever engineer a new item to be incompatible with older products made by their competitors, but there are many examples of such behavior from the early days of computers.<br> That being said, the "<a href="http://www.canon.com/camera-museum/history/eos20th/eos20thAnniversary.html">Electro Optical System</a>" has been pretty well pried apart by the competitors over the many years since 1987. So practically, you can buy new bodies and fit almost all older EF-mount lenses to them, but not <em>quite</em> all.</p> Link to comment Share on other sites More sharing options...
model mayhem gallery Posted September 21, 2012 Share Posted September 21, 2012 <p>I shoot with a Canon 5D Mark II and Caon 30D using both the Tamron 28-75 and the new Tamron 24-70 F2.8 VC. I would also highly recommed teh Tamron 70-300 VC. Great combination. However, discussing the LCD thing... It is funny when I use Adobe Lightroom Version 4 it is able to automatically select the correct lens when I shoot with my L-series lenses, but I haev to manually find a select the right lens when I shoot with my Tamron lenses, strange. <br> Doesn't matter this is very trivial and nitpicking. </p> Link to comment Share on other sites More sharing options...
larry_rabon Posted December 23, 2012 Share Posted December 23, 2012 <p>I am using the Canon 6D with a couple of Canon lenses and one Tamron lens: SP 24-70mm F/2.8 USD Di VC (the newest Tamron 24-70mm) I'm not sure that this is a compatibility problem because I get great pictures with this Canon/Tamron conbination. But one thing I have noticed is that my battery drains quickly with this particular Tamron lens attached. With Wi-Fi off and GPS off and even with the camera completely shut off, the battery will drain overnight with this lens attached, and even more quickly if I am shooting with it. I have not found this to be the case with any Canon lens I have used with the 6D. Has anyone else experienced this problem? If so, is there a solution?</p> Link to comment Share on other sites More sharing options...

You would need to do the corrections in post using Lightroom or DXO or similar. </p> Link to comment Share on other sites More sharing options...
