EF 24 F2.8 Feels funny when I mount it on my 5D ?

You have a "non L" lens and are attaching it to what is essentially a "non L" body. Your experience sounds like a typical "non L" experience. What are you hoping for? Does the lens work on the body?

I don't mean to sound "elitist". Despite the myths about how good the 5D and some non L primes are, there is still an aesthetic difference between them and their much higher priced counterparts.

"Despite the myths about how good the 5D and some non L primes are, there is still an aesthetic difference between them and their much higher priced counterparts."

Just how does the "click" when you mount a lens differe between the professional premium bodies and lenses and the stuff the masses use? Is it a more musical note?

Fine, my comment wasn't intended to disparage the 5D. If you can't justify the 1Ds3, the 5D is the next best thing. And if you can't justify the cost of an "L" lens, then a non L lens is the next best thing.

In short, if you "love" your 5D, you'd have a head-over-heels love-at-first-sight nothing-held-back love-hunger-craziness for the 1D series. If this equation ever changes, I would suppose that Canon stops offering the 1Ds series at 4x the cost of the 5D. Professionals who buy the more expensive bodies do it for a reason, IMO. It's not an ego thing...If I could get 1Ds results at 25% of the cost, I'd do it in a second. Unfortunately though, it ain't happenin' anytime soon.

Jon, if your lens isn't clicking when you mount it, and isn't mounting smoothly, there is possibly something wrong with it. I would send it back and get another.

I had a lens ounce that didn't mount properly. The replacement was fine.

I don't know but my non L lens the 100mm f/2.8 Macro USM makes the same click as the 24-105mm F4L IS USM and 100-400mm F4.5-5.6L IS USM. Personally I would take it to a trusted camera shop perferably Canon certified and have them check. Or maybe just call Canon and ask them, better to sound like an idiot if nothen is "funny" than mess up eather the lens or the camera. Just my 2cents worth.

The 1D series have an rubber o-ring and many L lenses also have an o-ring. So when you mount the two it feels tighter and very different than cameras and lenses with o-rings. With that said, my EF 24 2.8 is a bit looser turning than my L optics with o-rings but is solid otherwise.

You might check the lens and make sure all the screws are tightened down in the mount area. If one is sticking up the lens may not rotate all the way when mounting. I've had a few work loose over the years. A couple turns with a small screwdriver and all was well.

I don't hear or feel any difference when mounting L or non L glass on the 5D.

You must have the "Made in Canada" models!

>>You must have the "Made in Canada" models!<<

No, no. I just don't hear any difference between my 70-200 IS and my 50 1.4.

The zoom has perhpas a slighter increase around 976hz, probably due to the deeper cavity where the rear element is mounted. However, in tests performed in an anecoic chamber using an Earthworks measurement microphone these differences in clcik frequencies maybe further investigated by those who feel troubled by my empirical finding. I must admit Santa Monica BLVD is pretty noisy...

Just to answer your question, I pulled out my 5D and mounted my 24mm 2.8 lens. Mine is smooth and snug and makes a nice click.

And just to answer the smart alecks who knock our fine camera, it's a perfectly professional camera (might not last as long as the 1d's, but you can buy 2 or 3 for the same price!) A few of my non-L lenses are superb. Unfortunately, the 24 2.8 is not one of them, but it's ok and probably as good as the "L" zooms at the 24mm focal length, at least if you stop down a little :) It sure is a lot more fun to carry the tiny 24 2.8 around than an "L" zoom!

Jon Kobeck - your lens should click normally just like any other. If it's not clicking now it may cause some problems in the future. Maybe the last part is not perfectly parallel. Check all the screws first and if it doesn't help - replace it. Can you take off the lens without pressing the button?

Ok it mounts securly, but there is NO click, I am returning it

OK, scratch what I said. while last night when I first mounted the lens it felt a little "tight" when I screwed the lens onto the body compared to my L lens, and there was no locking click. Today I removed the lens from the body and re-mounted it and now it is clicking. Seems to make the clicking sound lock every time I mount it. I assume it needed to "work itself in" ? So I guess I'll keep it

Is there really any difference at all in the physical parts used to make a series 1 camera lens mount and a 5D lens mount? I'm betting that they come out of the same bin at the factory.

I will say that there is a difference between the sound shutting a door makes on a Mercedes than on a Cadillac, but I'd also be skeptical about claims that a Caddy sounds a heck of a lot different than an upper-level Chevy.

Come on, people. No click = something not quite right. Has nothing to do with "L" this or that. The cheapest plastic-mount 35-80mm from 15 years clicks when mounted on the cheapest film Rebel. If you hear a click when mounting other lenses on this body, then it's the lens and not the body.

Keep the 5D. It is NOT a consumer grade camera. But think seriously about laying out some serious cash for the 24mm f/1.4L prime, which very definitely IS a pro-grade lens, and it will work beautifully on that 5D. I can guarantee you that.

Turn up the ISO to 800 or above on the 5D, open that aperture up to at least 2.0 wide, and fire away. In most situations, you will not even need a tripod. Try it. You'll like it:

There is a reason that the 24 1.4L is out of stock right now. IT IS A GREAT LENS, MUCH IN DEMAND BY THE PROS! There will be more in stock soon. If not, try Adorama. YOUR 5D DESERVES BETTER THAN AN El Cheapo 24 2.8.

Check out the reviews: "Oh, why did I wait?" etc.

You need the best lenses on a camera that good. Let me say it again in case you missed it: get the 24mm f/1.4L prime wide angle lens. It is special, really special.

And remember: it's about the glass. It really, really is.

Lanie: I had asked about the L glass on another thread. I will sum up what I had said. I was looking for something light and small for street work, nyc subways etc. I have a 24-70L but that thing is too damn big and heavy to work the street with. I did a little research and see the 24L prime is also not so small and light, which is why I went with the 24 2.8, 28 1.8, and 50 1.4. for my street work. Thoughts?

Well, the light ones are nice for street work. That is so true, and the 24 1.4 is not really light or small, but it works pretty well about town, in my opinion.

My larger point was that the weak point in your system is probably your glass. I have the 1Ds II, but the 5D almost matches it in image quality--and it is lighter!

I think Alan hit the nail on the head: it's about glass, and the L lenses are usually (not always) much better. Next time I read the Bible, I read the Alan Bryant Version (ABV).

Well, maybe. Or at least expensive. ;-)

While the 24mm f/1.4 L may be just the right lens for a few shooters, for some the expense of this lens would not be worth it. As always, it depends on what and how you shoot, and on what you do with the photographs in the end.

LOL :-)

But I'm afraid I'm not very helpful here. I've looked at those two lenses in detail, and my only conclusion so far is "I really wish they made a 24mm f/2.0".

i just received a new 35 f2.0 from B&H yesterday, and it doesn't really have a clean "snap" either, but the images are fine. Different quality and feel than the 135 f2 L lens I took off, but that's what I expected.

I have found it is important to use gold leads and monster cable when conducting accoustic tests on lens click sound waves. You also need a decent reference lens, such as an L prime like the 50 f1.2 to calibrate test equipment and provide the measurement benchmark. The extra weight and rotational moment of longer lenses such as the 70-200 L series makes then unsuitable as a reference lens for click sounds.

My 24mm f/2.8 makes me smile when it's mounted on my 5D, but I don't really think it feels funny.

Steve Martin once said the secret to stand-up comedy was to put a slice of bologna in each shoe. With that in your shoes while you're on stage, you feel funny.

Ok, I think we've covered just about... everything... in this thread. So, to come full circle, I'm glad the OP's problem apparently solved itself while we were here yakking.
