Canon 80D and Tamron (1st generation) 150-600 Issue (Page 2): Tamron has a 6 year warranty. I sent mine in because it wasn't focusing properly. They cleaned it and replaced some part...

Did you happen to notice...did it look like they cleaned your 70-300 while they had it in for the firmware update? My 150-600 has a lot of dust, and I'm hoping they'll take pity and clean it for me free of charge. :)

Tamron has a 6 year warranty. I sent mine in because it wasn't focusing properly. They cleaned it and replaced some part and now it' s better than new. 3 day turnaround... and no charge.

This seems to be a problem with the 80D and tamron. I just read there is a firmware update for the lens.

Yes, cleaned and calibrated and stated as so in the documentation.

That's what I was hoping to hear! Awesome!

I had the same problem with the Tamron 16-300 using it on my 80D. Worked fine with the 50D. Contacted Tamron and was told to send the lens back to them and they will update it for the 80D. I, too, love their 6 year warranty. Took about a week before it came back. Works just fine, now.

How do you like the 80D?

I had the same problem when I bought the Canon 5D Mark IV. I sent my lens in to Tamron Service Center, in New York. I was back in less than 10 days. They also cleaned, calibrated, and made adjustments to some of the elements, plus added my 6D specs, and 7D Mark II specs to the program chip, and removed the other camera specs of models I don't own. This makes the focus faster, and more accurate. Of course, it now will work with "live view"

I recently within the last month purchased the Tamron 16-300mm lens and my camera is an Canon 80D. I wonder if there is a need for Tamron to fine tune it for the 80D?

I'm so glad that they clean them. I have quite a bit of dust in the lens, and while I don't think it has impaired my image quality, I believe it would bring down resale value if I tried to sell it. No plans to sell it, though, because it has been a gem for birds, wildlife and football.

And I suppose there are no pitfalls with Canon lenses...

For the large part, no there aren't any pitfalls with Canon lenses.

Virtually any EF or EF-S Canon lens made the past 25+ years will work "good as new" on 80D.

Canon EF lenses on Canon EOS cameras are almost universally backward and forward compatible. In fact, with L-series lenses Canon actually guarantees full compatibility with past, present and future cameras. With non-L, they don't make any guarantees, but there also have been almost no "issues"... ever... that I can think of. Certainly nothing like Nikon, where you can find chart after chart of lens/camera and lens/teleconverter/camera compatibility (and incompatibility) information.

One key limitation is that EF-S "crop only" lenses can only be used on the APS-C camera models (300D, 20D and later... 10D, D60 and D30 models preceded EF-S lenses and aren't able to use them).

The same simply cannot be said of third party lenses. It's because Sigma, Tamron and Tokina do not license technology from Canon.... They instead choose to reverse-engineer their lenses to work on Canon (or any other brand of camera, for that matter) and they have to avoid patent infringement, so cannot simply make exact copies. This gives pretty good assurance their lenses will work fine on current and relatively recent models, but gives no assurance of compatibility with future models. Come next year's new camera and maybe today's third party lens will work on it. Or maybe it won't.

Then along comes a Canon with a whole new (and neatly upgraded) autofocus system, such as the 80D. Canon has designed the camera to work with their own lenses, but has no obligation to make it compatible with third party manufacturers' lenses. So "stuff" happens. There have been quite a few instances of this with Sigma... probably because they have manufactured a wider range of lenses than anyone else. But Tamron has had its share of "issues", too. Tokina has had the least, but they also use one of the simplest and most primitive form of autofocus drive in their lenses. Compatibility issues can be with any of the lens systems that need to communicate with the camera to work properly: autofocus, electronic aperture control, image stabilization. But the more complicated and most frequent problems are with autofocus.

Gotta give them credit... In a lot of cases the third party manufacturers have offered free "fixes", sometimes even when warranties have expired. They've also done recalls at times, on current models. But some older third party lenses have become little more than expensive paperweights when the technological advancement leaves them behind. For example, I've still got an old Sigma 28-75mm that works great on any EOS up to 30D, but will lock up any camera later than that (at least all the models I've tried). No fixin' it, either. It's too old and not valuable enough. I kept it for occasional use on older models and film EOS. But gotta say it's just gathering dust now.

Canon themselves seemed to have a few small "glitches" with the 80D's unique, new autofocus system and some of their own lenses (I think I recall some issues w/teleconverters or with certain lens/TC combos, for example), but appears to have ironed them all out quickly.

So you have several locked up cameras that can't be fixed I take it.

The 80d has a few nice features that the 70d didn't have, but as far as handling or image quality in my day to day use, I'm not seeing much difference, other than the extra megapixels.

The 80D offers two custom setting modes on the control dial versus one on the 70D. That's useful to me. The video snapshot feature is much nicer to use on the 80D than on the 70D. You can't shoot a still while in video mode on the 80D like you can on the 70D, though.

For what I use it for, the 80D isn't much of an upgrade from the 70D.

You may want to send it to Tamron. Since this lens has come out there may have been a new firmware update, and having it set for your 80D only will speed up the focus, and make it more accurate. Tamron will also clean the lens, and calibrate the internal parts and the elements. Give them a call as see what is said.
