50mm Summilux Asph lens hood off!! [HELP Please]

Any idea of what size screw is required here? I just noticed that mine too has fallen out. I'm in Australia and will do anything not to deal with Leica Australia. 

[tedd]

Somehow found it in my camera bag. I fly a lot for work so perhaps the vibration of a plane allowed it to pop out? I'll put it back with a tiny dab of Loctite.

Nail varnish will be enough instead of Loctite.

[tedd]

Too late for that! I used a lower strength Loctite, put a dot of it on some paper and then just touched one corner of the screw in it while it was attached to the (magnetic) driver. 

I was surprised at how many mentions I found of this screw falling out after doing a Google search, seems like it should be really hard for it to work its way loose like that. The screw is ridiculously small though, so that possibly plays a part. It was an absolute miracle that I found mine. 

[Kl@usW.]

The retractable sunshade, the ring with the filter thread E46 and the cylinder holding it all together are held by just that tiny screw. If you screw in or out a filter, or pull the sunshade out, or push the sunshade in....the tiny screw and its tiny thread have to manage the torque and the shear force. 

There are few places where  this calamity is less wellcome than in Lapland in winter time , -25 Centigrades and while snowshoeing.... but exactly this happened to me while screwing in an additional sunshade. And off went the screw.  

I did what apparently is possible: take photos without hood. 

My advice: never ever hold the lens barrel while manipulating the sunshade or the filter thread, hold the lens  as far to the front element as possible lest  the screw is not sheared off. Undoubtedly bad engineering.

Well, my hood just popped off this weekend.  I called Leica DC and they were absolutely unhelpful and wouldn't even give me contact info for Leica Parts.  Leica parts would not send me the screw and insisted the lens has to be sent to them for servicing, they would not send me a replacement screw.  9wk wait time.  

 

Then I called DAG camera and they offered to send me the screw for $10 which includes shipping.  I've got loupes and I figure if I can change light seals for my film cameras, I can get this screw back into place by myself.  Just reviving the topic in case this happens to anybody else.

DAG is a great resource.   Placement is as easy as it gets unless the screw head broke with the threads remaining in the lens barrel.  This can be easily seen.

I've stripped my lux 50 a few times to sort out a slight amount of back and forth slack that gave it a little focusing 'slop'. It also had a stiff focusing issue too so I have had that screw out a lot. I should probably put a dab of nail varnish on it as it's probably going to fall out on me at some point with it being in and out so many times. Luckily, it's a 10 second job with the correct screwdriver.

iFixit kit is ace for working on the lux

It has everything needed for most jobs like this. Can highly recommend.

Leica Wetzlar took care of my case back then for me, zero costs charged. It took some weeks but all perfect. I guessed it was a simple fix but I didn’t dare touching that myself 😅

I confirm that you can't mount the filter without the barrel piece... But that doesn't bother me, I'm just concerned about the best/most efficient quick fix of this now... It's amazing that these issues happen on a $4,000 lens... Leica, gotta love them whatever it takes...

Did you buy the lens used?

I once tried to buy a new Lux ASPH hood from Leica Australia after denting mine. Like you, they refused to sell me a replacement hood and demanded a full service of the lens. Needless to say I've now gotten used to the dent. 

It's absolutely pathetic behaviour and honestly soured me on the brand a bit. Replacing that hood is easier than loading film into an M2.

I made a tool for this - much easier than complete disassembly! Haven't needed it since, but nice to know it's there.

I once saw a replacement hood on the Leica Miami website, but at USD100+ I put the purchase off and am now like you absolutely content with my dent.

That's cool, wish I'd seen your solution before.

I tried to do something very similar with one of those cheap small screwdrivers you get every now and then from random eBay purchases. The difference with my method was how dumb I was being in that I was trying to get right in to the tiny flathead screw that pushes the two 'arms' outward to brace more tightly and therefore get rid of the 'slop', rather than remove that entire piece first. 

You can see from the photo that the tiny flathead screw has taken a beating because it's quite delicate and I'm trying to tighten it at a strange angle with a bent up cheap screwdriver while it's still deep in the lens, not really ideal or the mechanical sympathy it deserves. It's a bit embarrassing but if it helps someone else fix their lens and not be a few hundred down and months without it, then so be it.

Once it finally dawned on me that I could just remove the entire piece and tighten the flathead screw very easily it was a lot easier and I could have avoided chewing it up. I'm pretty sure your modded screwdriver is for getting that piece out more easily? I was lucky in that the iFixIt kit driver heads are quite thin and carefully undoing the screws at an angle was OK although not really the proper way to be doing things.

Better to use your custom screwdriver as less chance of damage to the screw head and easier to gauge tightness, but overall a thin angled screwdriver works just in case anyone else is in a pinch.

Photo of cactus is an after surgery photo (RAW grabbed from Google photos and just saved out as jpg and downsized for upload), lens has no slop and is super smooth and quality of photos is superb as always.

I was lucky, my friend found the hood for me but the screw was nowhere to be found.  I agree it's really bad policy on Leica's part, though the woman at Leica Parts was very nice and tried her best to be helpful.  I got the screw from DAG about a week after he mailed it out, and total repair time for me was about 20 seconds.  

 

It's really weird how the optics of the lens can be so outstanding but the hood is really spotty engineering design.  It shouldn't be held in place with just a single screw, especially since it's a retractable hood that twists.
