fixing a broken DAL 18-55 plastic mount

Hi folks,

The plastic mount on my kit lens 18-55 DAL broke when it fell while on holiday last year, and I had since replaced it with a DA 18-135 WR. Recently, I decided to get my kid a used K100D as a starter DSLR, but it did not come with any lens. I'd been looking around for an 18-55 for him, but was wondering what others' thoughts are as far as trying to get the 18-55 fixed. Is it actually worth the cost and effort or should I go looking for another 18-55 online? Speaking of effort, where DOES one go to get this fixed? I'm in Canada, so don't say Henry's :-) as I'm sure the cost will be more than the lens itself! Thanks to everyone for any suggestions / comments.

I think these DA L 18-55mm are pretty cheap on the second hand market, probably not worth your trouble unless you enjoy tinkering with this sort of stuff. Maybe you can sell it online to someone who does like tinkering.

If it fell hard enough to break the plastic mount (not an easy thing to do) then there is always the likelihood that you have issues with misalignment of elements and/or other internal problems. Given that the lens goes for $40-60 used I'd suggest just getting a used one that is in good shape.

I would just replace it for the $40 to 50 they sell for. Guy in St. Catherines has an 18-55 II plus a Sigma 70-300 listed for $90 right now, if you are up for a road trip (hit Niagara too?) or if you can convince him to ship: Camera Pentax Lens - Ontario Cameras For Sale - Kijiji Ontario Canada.

Alternately, post a wanted ad for $40 (or less) on Kijiji and you have a decent chance of finding somebody with an extra one (or more) kicking around the house.

+1 - any impact hard enough to damage a DA L mount has likely done other damage.

(And I am of the opinion that any impact hard enough to damage a DA L mount would likely have caused internal damage to a DA lens too - but wow! your metal mount would have survived - who cares at that point?)

I'm curious--was the lens mounted on the camera?

If so it likely saved the much larger problem of damaging the body.

Heck, for the cost of the used 18-55, you can maybe get a used FA 28-80/90/105/etc for cheaper. Not as wide, but it would have more range.

Also, this is actually the first time I've heard of a plastic mount actually breaking, so yea... I'd suspect more damage then just what you can see with it. Keep it, and see if you can reverse mount the thing for macro work or something.

The Henry's outlet centre in Missisauga has lots of the used 18 -55 lenses for less than $50.

Actually, have you tried using the lens since the mount was broken? The missing contact may not be one for encoding the aperture value on a f/3.5 lens, in which case depending on what else is broken internally or on the mount you may be able to glue or screw down the broken portion of the mount ring and continue using the lens. It may not be pretty, but I would consider the lens only worth repairing if you can do it yourself without too much effort.

@Primes4ever: Yes, but they tend to be dirty and come without caps or a hood. Even a moderately well cared for Craigslist lens will likely be in better shape.

wow! Thanks to all for the great comments / suggestions!

Primes4ever:
thanks for the tip! I never knew Henry's had an outlet centre. I work downtown and the Henry's downtown store is pretty near my office - I actually bought the DA 18-135 there.

Sagitta:
Yeah I hear ya. I just bought the K100d from DucDao (thanks again Duc!), and he had another lens too, but I felt that it wasn't wide enough for my kid to start learning with - and what a great idea to reverse it for macro!

dms:
Yes, it was mounted on the camera at the time. It actually fell less than three feet onto a carpeted floor, but it was the angle at which it fell, and yes, that crack actually saved the camera from any damage, so I should say it was a lucky break!

JimJohnson:
I personally dislike plastic mounts too, but I guess this time around, I should be thankful it was plastic :-)

Docrwm, Na Horuk:
Very good point - thanks for the advice.

Steinback:
Thanks for the link! I never thought to look at Ontario listings - had only been looking at GTA ones.

@Steinback

Yeah I tried, but the mount was so warped, I couldn't get it to stay on. The aperture release mechanism is still pretty smooth. But yeah, I'm not good with tinkering with lenses - my 'skills' at fixing computer-related tech has sadly not transferred over to the photography side

Hmm.. very good point about the outlet stuff's condition.

The DAL18-55, Da18-55vII, & DA18-55WR are all the same optical formula. Only the DA18-55 (no version designated) has the old formula optically.

Drew,
The 18~55 is quite a good lens on M4/3 and I machined an adaptor for it.
Not wanting to interfere with my good lens, I use heatshrink plastic to hold the aperture at f/8 or so which is a bit limiting.

If I had your damaged lens i would try to take the back off and machine a whole M4/3 back end maybe with some aperture control.

I would simply try some epoxy glue to get it back in operating condition. It dries in five minutes so you can simply hold the mount in such way that it'll set properly (maybe). If it won't work, what's the loss? Few $ for the glue, the lens itself is pretty much worthelss as is...
