Let's see your Leica M

What is the new hood? Where did you get it from?

It is likely the limited run of round vented hoods that Leica made for the 28mm Summicron ASPH and the 35mm Summilux ASPH (pre-FLE). Leica part number 12466, give it an image search on Google... pretty little thing.

They're hard to come by If you do manage to find one, brace yourself as you look at the price of one of these things 🙄

Hi David,

No, that's not it. I have been looking at the 12466 for a while. This looks like something that is screwed on the thread of the lens. Plus the 12466 does not have a uniform front ring, it is sort of slanted.

I understand the 'look' of a hood, but its a fact the square hoods do a better job of doing what they are suppose to do - keep stray light that is not in the frame off the front element and into the lens. Some lenses can handle some stray light (those flat front elements help in general), but there is the fact that extra light can cause veiled flare (not as noticeable as the flare we easily see on a photograph) and lowers contrast.

Leicas are pretty compact as it is, even the larger hoods don't make the system too much to handle. But if you want a nice looking hood, and/or it does the job good enough...

That said... I'd love a 12466 (metal and clip-on, pretty good coverage and cutouts at the corners) for my 35 LUX aspherical, but for the cost ($400+/-, one sold on the bay for $600! recently) I'll get along with the standard hood, or go naked if I really need a more compact lens.
 
fwiw, the Leica #12589 hood (for the previous 35mm Summilux ASPH non-FLE) works perfectly fine on the 28mm Summicron ASPH. http://www.adorama.com/LCLH3514MN.h...ch=1&mobile=&gclid=CL-duL2ar78CFQGTfgodXLoAZw

Plus it's relatively inexpensive (for Leica.) You can also find them used for $100 or so.

The 12466 may be nice looking but the price makes no sense (to me.) The 12589 is a square hood that does the job and maybe even better than the 12466 (?)

Although I find that the 28mm Summicron isn't that susceptible to flare as it is, and it's actually a very compact lens without a hood.

One reason behind the #12466 hood is as a fix to one of Leica's frequent design oversights:
The 28mm Summicron lens is prone to separation - caused by rotational forces between the body and lens hood.
The 35mm ASPH , well at least my early one , also developed a wobble and needed tightening - I suspect for the same reasons ( thought the 35mm hood is the better, i.e. smaller , of the two originals )
The round hood creates less stress on the lens when e.g. it's taken out of a bag.

Given that, the price they charged to correct their mistake is even less acceptable. I admit to biting the bullet and buying one before the limited run of them sold out ... and the price almost doubled ( for once I wish some enterprising machinist in china would sell copies )

I have heard that the hood that comes with the 28mm Summicron might potentially cause stress and that is what is thought to be the reason for the front loosening up. That hood is gigantic. But how does a round hood make any difference over a smaller square hood? I wonder if it's more to do with the screws that hold in the front element unit; i.e., the design of the lens build itself. And maybe too, that some users will tend to grab the lens by the (huge) hood.

But wouldn't a round hood (like the relatively large 12466) also potentially create issues? Isn't it large enough (diameter) to bump the lens when you set down the body on a flat surface?

I'm just curious because I've heard people blame the Leica supplied hood for the lens getting loose but I wonder if that has been quantitatively proven or if it's really more of a lens build issue. Although I guess combined with a big hood that it might become more of an issue.

I've been using the 12589 for almost two years now but only because it's smaller and more compact. My lens hasn't (yet) become loose. However I did send it in to Leica when I first purchased it because of focusing issues. The invoice said that the tech also "replaced front element screws and 'serviced' it." I wonder if they now have different screws and/or use Loctite, etc..

Anyway, I've been using it now more often without a hood.

My thoughts are that the large flats on a rectangular hood are more easily caught and twisted - it's more difficult to catch and turn a smooth round surface.

I think VertovSvliva has it right. Its not that the square design puts more stress on the lens ‘in the bag’, but that users have a tendency to grab the hood when taking the lens on and off the camera. The 4v 35 Summicron is a good example as its a common problem, the front lens mount is held by glue instead of screws. The glue weakens, torqued and age, and the front lens assemble can become loose.

The first time I saw a 12466 was in a very expensive special edition Hermes set Leica-M with a 35 Summilux ASPH. I think Leica was going for the ‘look’ of the more traditional round hood, better made in metal, with the chip-on style, and clip-in hard plastic front cap. Much better than the thin plastic strange rotating lock of the original 35 LUX ASPH hood with its thin front cap that slipped off (and got lost). They probably had made more than they needed and produced some in black chrome for sale - at a price.

BTW: never lifted or mounted lens holding the hood.
