Is this new lens being an EF mount, compatible to a Canon 6D or is it proprietary to APSC only bodies like the EF-s lenses.
I have been watching several reviews and they mention 6D but not whether it is actually compatible. Any help would be appreciated. I own a Canon T2I and a 6D with a 24-105 version I and a 70-300L and was also looking at the Tamron 150-600MM G2. My Idea was maybe just get the 18-400 and just use it on the T2I.

The 18-400 is not for full frame.

In case you have more to check out, go to one of these sites. Usually tech specs are included.

It sounds like the 18 - 400 won't work on your 6D, but I know the Tamron 150-600 G2 is very nice on my 6D. If you need a long lens, I highly recommend it. AF on the 6D is just fine with this lens.

I think some of us are contemplating this smaller lens because of the size and weight compared to the big boys. My wife wants one for ease when hiking. Anxious for some feedback. My guess is that it will be acceptable for her intended use.

well that cleared that up.. I can only assume it is just days before it is there for NIKONs too.

The Tamron 18-400mm is designed as a crop sensor lens, however, ANY crop sensor lens from Tamron or Sigma will mount and function just fine on your 6D, or any othe full frame Canon for that matter. It is ONLY Canon branded "EF-S" lenses that will not mount on the Canon full frame cameras. The only drawback to mounting a crop sensor lens on a full frame camera is that these lenses are designed to project a smaller image circle and that image will not cover the larger sensors diagonally, leaving you with a dark vignette in the corners. Some crop sensor lenses will actually cover that larger sensor when zoomed out to their tele end. I just checked the Tamron 18-400mm on my Canon 5D MK IV body and it worked excellently, except for the vignetting, which on this particular combo did not completely go away when zoomed out, even at 400mm.

The 18-400 Tamrons are readily available in both Nikon and Canon mounts right now.

Will not fit on a full frame camera

Maybe you're putting it on backwards. Turn it around, it'll fit quite nicely.

It will actually fit just fine, but will vignette badly to varying degrees depending on the focal length, as a result of the smaller image circle of this crop lens.

The reviews I've seen indicate quite good results for a superzoom, but show significant softness at 400mm, which was not unexpected. What has your experience been?

Based on reviews I've seen it may be quite soft at 400mm, unless stopped down quite a bit, Hand holding at 400mm may also be problematic.

That's a safe assumption for me! My wife is looking at it for her use. She's still steady! I'd go with the 70-300 if I was her, but she likes the lower end as well when hiking. I'm good with what I have and I am trying to behave.
