Yes sir they did get quite a run out of the 18MP Rebel sensor.
What is your first grandchild? A little boy or girl? I have nine. 6 girls and 3 boys. All the girls love to have their pictuers taken. And I love shooting them.
Second oldest is below. Ain't it great?
It is indeed, Ernie (and that's a great picture, BTW). Grandparenthood affords many of the fun features of parenthood without any of the responsibilities. I have five grandchildren, ranging in age from 10 to 17. And it's easy for me to keep track of their ages, since their birthdays all fall into a seven-week period from December 25 to February 12. 
GRANDPA POWER! 
I am so jealous, I can not remember birthdays or even how old they are. But I have nine. I think that one is 20. And her birthday is........well she was born, I was there.

if you do get a 6d you should also consider pairing it with the Tamron SP 24-70mm 2.8 Di VC usd, for some odd reason canon doesnt have a 24-70mm 2.8L lens with image stabilization
the 18-135mm stm is garbage and the sigma is a bit hard to sell off when your done due to its bulk and people not wanting to be stuck with a efs mount lens
as for the the 24-105 f4L (IS) starts off sharp but drops in resolution at the other end and at f5.6 to f8 you would have trouble trying to spot the difference between this and the kit lens on 40d
Wow, you're pretty hard on the 24-105L. The only real knock against it is that it is not state of the art. I wouldn't expect a 40D to realize much of the potential of the lens. But, on a 6D it looks pretty darn good.
That shot was taken with a 6D at 24mm, f/8, 1/160, ISO-100. from a slowly moving and rocking boat.

Just curious, are you a user or just a reader? Never waste a bad review.

I think the 24-105 f/4L IS on a 6D can produce some pretty sharp photos. Can you see something orange in the top left window?
It is one of the lighthouse museum's curators, the boss. She oversaw the multi-year restoration project. There are about 12 more people/hosts in orange shirts hiding out on the inside, just so that folks can take clean pictures.

a user, I used to have ef 24-105 f/4 usm L (IS) sold it cause i wasnt using it after aquiring the tamron 24-70 f2.8 SP Di VC, and I'm not that hard on the lens, i was refering to its the performace on the 40d and to be honest i find the kit lens 18-55mm f3.5-5.6 (IS) & 55-250mm (IS) f4-5.6 to be adequate on all aps-c bodies (even more so now newer bodies correct for chromatic abberations and peripheral fall off) I'm still shooting with the made in taiwan 1100d which only has the peripheral fall off correction
"just get a 6d and throw the 50mm on it and zoom with your feet "
But you recommended a 6D and a 50mm? If you never used a 6D how could you recommend it to someone else? Or, how the Canon EF 24-105mm f/4L IS USM Lens will work on it?
That is what I was wondering?
I share you thoughts on the Tamron SP 24-70mm f/2.8 DI VC USD Lens for Canon. It is a wonderful lens which I can highly recommend from personal experience with it. My personal rating puts it in 2nd place to the Canon EF 24-70mm f/2.8L II USM Lens. Maybe a distant second but 2nd never-the-less.

I admit I've never used a 6d, but i have used/hired the 1Ds mark2 (about 45 hours) and the 5d mark2 (3 weeks), but if i were to go out tomorrow and buy a fullframe camera it will be the 6d because i dont shoot for a living
