04/06/2006 04:33:48 PM · #2

Never!

Im Good with tools, and I do take mine apart on the front side only, the Camera side has the electronicts in it. I myself wont go there.

Taking them apart is easy.... it's putting them back together that I haven't figured out! :/

You could. But could you put it back together?

Edit: Damn! Beat to the punch!

I want to get one and take it apart and take out the appature and stuff and try and fit it on my S2.

Could i do that? gut it but leave in the lenses that it needs to work like a teleconverter? a 52mm or a 58mm one?

Any that you would recomend?

buy the 50mm f1.8 and try it.. it's less than $100 so you won't loose much by playing with it...

just don't start with the 85mm f1.2 L.. $2100 is too much for anyone to destroy ;)
04/06/2006 05:15:13 PM · #8
dang, $100.! i was thinking like $5. there are some that people more or less are just giving away. If they dont sell they probobly just pitch em.

How do i know the ones that have threads? some look like they have little prongs that turn and lock. I would need a threaded type. What are they called? so i could narrow the search.

Do the older older 35mm lenses screw in?

I once dropped my 50mm f1.8 (about $100) on cement creating fixed apeture lens (the focus ring still worked). Rather than taking it in, I, after several bottles of beer, popped it open to see if there was anything I could do to fix the problem ...

Several days later I bought a new 50mm f1.8 lens ... for about $100.

You still have the old one? how much?

Somthing like this would fit a 52mm adapter with the 50-52mm step up ring?

I did once, the front element now works as a very nice magnifing glass

You must ask fotomann forever - heard his lens accidently got some peanut butter and pleny of cheese on the inside. All his photos since this very unfortunate incidents contains imnages of cheese.

He had to open his lenses to clean them.

is 50mm the thread size? is that the biggest thread size for the SLR lenses?

I think your going down a road where you will just end up breaking something and totaly regret what you are doing. I just took apart 2 lens acouple days ago a 70 300 5.6 zoom for an old pentax just to see how it all works, anyways the drill some came out becasue of striped screws and you can see where things went from there. I ended up learning alot but I also had a lens with about ten holes in it. Good think I'm never going to use it. I also took apart a old 50mm 1.4 which was easy as pie after taking apart that zoom but it seemed like to much work to put back together so it hit the trash can. great learning expirence but I will never do it again.

I wish I had thought of that. My broken lens just glowered at me from the shelf for several months for my negligence before I gave it a proper burial.

So you dont think i could gut it but leave the last lense in it or a few at the end and it would be usable? How many lenses do you think you took out?

Getting it apart is the easy part, it's getting all those tiny pieces to go back together without any leftovers that's the real trick...
04/06/2006 05:44:36 PM · #18
Procedure:
Step 1: Prepare working area
Step 2: gather tools
Step 3: Use hammaer and chisel to separate the sections
Step 4: dump entire mess into the trash!

But i dont want to put it back together. I just want to ditch the appature and the lenses near the threads.

Not unless you have been shown by a lens tech.

Just buy a new camera don't waste your time trying to take one peice of glass out of a lens

Get insurance, try it, and if you screw it up, drop really hard. Maybe you'll learn something in the process.
04/06/2006 06:28:39 PM · #23
you guys are no fun.
04/06/2006 06:33:25 PM · #24
What do you expect most of us live for lenses. The thought of busting one up is just to much to take. Rikki posted a while ago about how he dropped one at a hockey game. I heard a collective Nooooooooooo! By the DPC community.

Glass addiction? Yes Please!

:)

The thread size of the 50 1.8 should be 52mm. B&H has that info on the lenses they carry, which is most current ones.
