Canon 24-105 F/4L

[TrumpetPower!]

However, after reading your inputs, seeing the photo and knowing what a full frame can do at f/4. I'm now considering selling the Sigma 70-200mm f/2.8 and replacing it with a Canon 70-200mm f/4 with IS.
 
Your thoughts?
Would you sell the Sigma f/2.8 to purchase a Canon f/4 with IS?

What do you use the 70-200 for?

If landscapes, the Canon f/4 non-IS is perhaps the best choice, with the IS model being a good alternative if you tend to eschew tripods.

If sports, all you care about is speed, so f/4 anything is generally a poor choice.

If weddings, IS isn't going to stop people from moving at slow shutter speeds, so you again want as much speed as you can get in addition to IS.

Horses for courses and all that....

Cheers,

I currently have a T3i with the kit lens, a Canon 50mm f/1.4, Sigma 70-200mm f/2.8 EX DG HSM II Macro Zoom Lens and a Sigma 17-50mm f/2.8 EX DC OS HSM that I'm selling.  I will be buying the Canon 6D with the 24-105 f/4L  In your opinion will I be able to get low light shots with the  24-105 f/4L on the 6D, as I have with the Sigma f/2.8 on my T3i?

Yes, all you will need to do is shoot at one stop higher iso. IE, if you are shooting f2.8 on the t3i/sigma combo at iso400 you can get the same shot with f4 on the 6D/24-105L combo at iso800. The DOF will be will be pretty close as well. The big plus being the 6D will have a lot less noise even shooting at one stop higher ISO then the t3i.

Not familar with the sigma, is it IS?  If not, another advantage to the 24-105.  My favorite walk around lens.

I wanted to thank everyone again for their inputs, I'm happy to share with you, that I've place the order and I should have the 6d with the 24-104 f/4L lens Friday.

Congrats!  you won't be disappointed.  I'm on my second 24-105, not because there was any problem, but rather that I sold the first one for more than the difference between a 5d3 body and a 5d3 kit.

I acquired the 24-105 as the kit lens with the 5d3, I didn't really want it but I needed the camera for a wedding. I loved that lens right up until my wife stole if from me for her camera. Its a remarkable lens, take it you won't regret it.

Enjoy the lens.  I have been using it for years and it is my favorite walk around lens.

Geez, I wish I had thought of doing that when I bought my 5D3 in December. I've had my 24-105 for 7+ years, and even though it still takes great shots, it suffers from zoom creep, which I haven't been able to remedy.

Black insulation tape, round the extending barrel part. Put it at the end of the barrel that will keep the barrel in its retracted position, when you retract it.

Mine's been working just great like this for a while now.

Naysayers and doomcasters will warn you that this remedy will kill the lens, murder your wife, and be rude to your aunties.

Rubbish. It's a simple, easy, common-sense fix, and carefully-done, looks just fine too.

Which is why it'll remain my standard zoom for the foreseeable future. Like, say...until Canon releases the TS-E 12-1200 f/1.0L DO AF for $999.

12-1200 f/1 is a great idea.  Perhaps they could get it to the $999 price by just sending us all the parts and we assemble it ourselves.

as i've said before if you are happy with the 18MP crop sensor image quality at 1600 iso then you will be fine with a 5Dmk3 at 16,000 iso would imagine the 6D would be pretty similar

Just added the 6D and 24-105 2 days ago and first shot with it yesterday.  I keep trying to talk myself into selling the lens but I can't come up with a better alternative.  I'll have the 21 Zeiss on the 6D and this lens will be on the 5D II at the same time(figure it'd be best to run two bodies for the rare times a tornado is passing close by and no time to switch lenses lol).  The wide shot will be happy with the Zeiss, like a lot happy as it is amazing.  I'm having a fit in my head if I need the zoom or not for the second body and not just a 50 or 85 prime.  The thing is, at 50mm the 24-105 at F4 is dam similar to a Sigma 50 at F4.  But yeah not at F2  .  The good thing is 24mm is clearly its weak end but by quite a lot.  Need to see just where that gets better between there and 50mm.  35-90mm might be really damn "happy" with that lens and that would be great.

I'm a little shocked just how bad the color fringing is though.  Sure it can easily be removed but it sure isn't helping things.  Vignetting wouldn't be as annoying if it wasn't such a sharp change and was spread out a bit more.  For sure that would be a very damn fine lens on a crop body.  And even full it seems pretty darn happy inside 24mm and to a lesser degree also inside 105mm.  Edges are a billion times better than the 17-40 ever was anyway so there's that lol. 

I've gotten rather picky over the last few years(even when I already know it doesn't matter for the image and old original rebel kit lens images will still be selling over everything else, making the point all the more lol).  Anyway, as anal as I've gotten, even on full frame the 24-105 is trying its ass off to get me to keep it and use it.  24-70 F4 sounds like its weakness is in the middle.  Screw that then.  24-70 F2.8 I may as well just go 50mm since there will be a 21mm on another body anyway. 

I hope you got a good deal on it.  It was $2330 or something like that from Amazon, which if one then wants to sell the 24-105 anyway, for like $800, then the body was only $1500.  I think Canon's rebate deal ends today on things.

@ TrumpetPower - yes, me.

Thanks you all for your help, your replies and comments.  A special thanks to TrumpetPower and Neuroanatomist for their inputs and awesome photo.

 I wanted to update you on my post/status, I've was able to sell my Sigma 17-50mm today for 515.00, I really liked that lens on my T3i.  However, I'm very excited about upgrading to a Canon 6d and the 24-105 f/4 and the lenses I already own the Canon 50mm f/1.4 and the Sigma 70-200 f/2.8 without OS.

Would you sell the Sigma f/2.8 to purchase a Canon f/4 with IS?

I had your exact situation (well almost). I had a T1i and the 17-50 Sigma. Loved that combo. I was also worried about going from f2.8 to the F4 of the 24-105 that would come with the new 6D. Well I am pleased to report that the only thing I miss from the Sigma is the lens lock. From a versatility point and exposure point the 24-105 is just better on the 6D.
