L Lens and EOS Rebel T3i body

[calilove27]

I've been asking so many questions on here, haha.
But I'm here with another question. So I've somewhat been researching on the net about using L lens with a t3i and quite a handful of people are saying that they wouldn't work well together? So L lens aren't recommended for EOS Rebel bodies? Can someone explain this to me please.
I just recently bought the T3i and I just want a good lens. Preferably for landscape photos. I also take some sports, low light, and portrait photos.
Suggestions for landscape and all around photography lens would be great (:

Actually, I believe there are some differences with the L lenses. I own four of them, the 17-40mm, 100mm F/2.8 Macro, 24-105mm and the 100-400mm. None of these lenses work correctly on my GF's crop body SL1. I did use a 70-200mm F/4 L successfully when I used to use a t3i, but none of these other L lenses seem to work correctly on crop bodies. The 100mm Macro won't get a proper focus lock, the, same with the 24-105mm and the 17-40mm. The 100-400mm autofocus doesn't work at all on the SL1 unless using it in manual focus only. All of these lenses work perfectly on my 5DS R, 5D classic, 5D Mark II and 6D, but NONE of them work on either of the 2 brand new SL1's she has.

"...NONE of them work on either of the 2 brand new SL1's she has."

Whatever!  It is not the lens as there is absolutely no reason an "L" lens won't work on a Rebel or SL-1.  You need to look elsewhere for this problem.  If anything an "L" lens will perform better than any other lens.

i hate to say it, but the most likely explanation is operator error.  I have used almost all of the lenses you cited on a T5. 

I see no reason for the "L" lenses not to function properly on a Rebel SL1.  Just make sure the camera battery is fully charged.  The bigger lenses have bigger motors, which need more power than the standard kit lenses.

Funny as I called Canon this morning and they said that it is possible the L lenses won't work properly on the new Hybrid AF on the SL1.

Doesn't the 5D Mark IV have the same hybrid AF? If "L" lenses didn't work on the 5D4, we'd certainly have heard about it by now. Are you sure your SL-1 is up to date with the latest firmware?

"Funny as I called Canon this morning ....."  

One or the other of you misunderstood the question.

[liamphotography]

Latest firmware on both SL1's and L lenses still don't work.

[liamphotography]

No idea, but I doubt it's the same one as the SL1 I have not read everything on the Mark IV, but the article I read earlier said only the SL1, T5i and T6i had this new Hybrid system.

Unless you concentrate on the real issue you will not find the cause.  Get another SL-1 and another T3i and try them on it.

I personally have use "L" lenses on various Rebels.  They all have worked perfectly.  I have had a dozen or so Rebels and perhaps 50+ lenses over the years, they all have worked as expected.
