What size is the hood for the 24-105L IS?

Err, what do you mean by size? It is a petal style hood (EW-83H) that was redesigned after testers found fault with the original Canon design. The original hood never made it to market from what I understand.

not sure what you're asking. It's a 77mm bayonet mount petal style. 4 3/16" diameter at the end, 1 11/16" long.

Yes, with size I meant the physical dimensions. That is required information to know if lens + hood may fit in a specific bag.

4 3/16" should correspond to 106mm.

B&H links to the Lowepro Lens Case 1W for the 24-105/4 L, but the Lens Case 1W is 4" (100mm) in diameter, so it sounds like a very tight fit.

Next up seems to be the Lens Case 4s.

I follow you now. Yeah, the lens hood is over 4" in diameter. The 4 3/16 was across the larger two petals, the top and bottom. Across the smaller petals on the sides it's 4 1/8". Those are to the outside of the hood.

The leather bag that comes with the lens is 4 1/2" diameter (the best I can measure the flimsy thing.)

My assumption is that the lens pouch that is supplied with the lens is similar to what is supplied with the extenders.

I really like the Lowepro Lens Case series, since they offer a lot of protection, and most of them have the slip-lock system, where I can fit them on the outside of another bag.

Since the L lenses are delivered with a hood, it would be reasonable to think that B&H would link to a lens case with room for the hood...

Anyway, after reading http://www.burren.cx/p​hoto/alternate_hoods.h​tml it looks like I would be better off with the EW-83J, since I have a 1.6x crop camera.

Go to http://www.lowepro.com​/camera_matrices.aspx and download the Lowepro lens case matrix chart.

It suggests the Lens Case 1 for the 24-105. I have the Lens Case 1W for my own 17-55 lens and the hood does fit inside, albeit somewhat snuggly. The Lowepro cases have a bit of extra room that accomodates lens hoods, based upon several of my purchases of their lens cases.

Can I assume that you recommend Lens Case 1W, and not Lens Case 1?

The LC1 would be a perfect fit for a 24-105 without hood.

LC1 is smaller than LC1W so if your 17-55 fits snuggly in an 1W, you would have to be violent to fit it in a LC1.

And if I don't buy a EW-83J separately, the original hood for the 24-105 may be even wider than the 17-55 hood.

I was pointing out that a 24-105 with the usual Canon hood should fit in the Lowepro 1 case; Lowepro recommends the 1W case for my 17-55 with standard Canon hood and it fits fine. If instead you put a hood intended for a different lens, such as EW-83J on the 24-105 lens fitted on an APS-C body, the Lowepro-recommended case might not fit, since you are using a different hood with a different diameter.

if you flip the hood, it should definately fit anyways, right?

Part of the reason for the thread is that I think that the Lowepro list has to be taken with more than a pinch of salt.

They say that a 70-200/2.8 IS should use a LC3 - it does.

They say that a 100-400 IS (a slightly shorter lens) should use a LC4, which is same diameter but 5cm longer than LC3. Maybe they considered the 5cm extra for a fitted 2x TC, but no such info seems to be available. Why not reserve room for a TC on the 70-200 too then?

Further, I'm not so sure that the pdf considers hoods in a consistent way. The list says that a 28-135 fits in a LC1. It does, without a hood. Not so with a reversed hood. The long petals are easy since the hood can flex. To get the short petals down too, you have to be violent - and don't care about how to get the lens out again.

I don't know the diameter of the EW-83J hood that you have on the 17-55, but I can't think the diameter is too much different from the 83H (106mm). I don't think a LC1 can handle any EW-83x hood.

The good part is that you says that a 17-55 with a EW-83J fits (a bit tight) in a LC1W. By implication, an 24-105 with a EW-83J (and probably the original EW-83H) should also fit (a bit tight) in a LC1W. The 1W has 1" (25mm) extra diameter compared to the LC1.

Thanks for pointing out the inconsistency of the Lowepro chart

Yes confirmed that they list case for 24-105mm without hood , vs. case for 17-55mm with hood. BTW, LC1W is 100mm diam. vs. LC1 is 85mm diam.

Ah, you are correct. I must have glanced at the 1N or 1S.

Well, thanks to the help I have received, I think I have sorted out my questions.
