I am looking to de-click few recently aquired Nikon mount zoom lenses (getting ready for F3). Where would be a good place in Toronto to do this?
Any experience?
Price?
Thanks!

Don't know of anyone. Best place is Duclos lenses in California. I'm thinking of sending my Zeiss ZF lenses to them. Lots of good feedback. All the lens guys I know don't do mods.

Sending it to US and than getting them back would be too complicated... What is the procedure for sending it for upgrade and then NOT paying customs on return? Experience?
Duclos looks interesting.
Wanna do "batch shipment"?
If yes, let me know.

I might be interested. I have a set of ZF's that need the works as well, what kind of deal you think we could get?

I have no idea. I was more referring to sending a load of lenses from Canada at once to make the return (over boarder) less hassle...

If a lens specialist like Duclos isn't an option for you could try a local Canadian camera lens repair shop near you to have them look at it. Its really not a very difficult undertaking that requires little dissembly for older Nikkors, there are several screws in the back of the lens where you can unscrew the rear and access the aperture mechanism (some lenses have screws up front after you unthread the front) . While I wouldn't recommend you doing it yourself a trained professional could easily figure it out.

Another option is the using a Nikon G-lens with an adapter with a manual aperture ring. MTF, I think, is coming out with one as they already have an EX3->F-mount adapter. I'm not sure the aperture ring works with non-G lenses, but it could. Maybe someone that has more familiarity with MTF F-mount adapters can chime in, or you could ask MTF directly.

You want to send them down "for repair". I did that with a lens last fall from Vancouver down to Van Nuys, CA. FedEx knew all about it. You get the form from them (just call em up) and fill it out in triplicate. Make sure down there that the lens place knows about the documentation. Otherwise if they don't supply it you are on the hook for HST/GST all over again. Sometimes people in the shipping departments don't speak English so you want to make sure they know the deal and will follow through when it comes time to ship it back.

If you do get dinged for tax, you will get it back once you remit your GST/HST forms at the end of your remittance period.

I contacted the shop I used before... They will look at this mod. Good thing is the price estimate is $40-$90 per lens... Worth a try...
I will keep you posted...

Does anyone know if this will void the manufacturer's (Zeiss) warranty if even done by qualified lens tech.

No problem!
If you call the shop, tell them that you found out "from Steven"... Apparently they have a service man every Wednesday in, so schedule accordingly. I am still waiting for my second Tokina to show up (from Yellowknife) and then I'll take my 2 zooms there...

Steven,

Does that price include cleaning of the lens or just de-clicking?

Thanks!

I am not sure how much "cleaning" they will include in the price. I can only tell you my experience from few years ago when I took an old Angenieux 28-70 to be serviced for too much play in focus ring. I got the lens back, fixed end clean...

I dont want to persuade you into something your not comfortable with, but a few years ago I tried to do de-click one nikon 50mm and its so easy to do its not even funny. Ive done about 10 different lenses of various focal lengths since with out issue.
Unless the lens is really complicated (most ai + ais nikons are not), its as simple as unscrewing the mount, pulling the aperture ring off- removing the balls- adding a tiny bit of grease (or not)- and putting it back the same way you took it off. Takes less than 5 minutes.

If you do a google search, youll find a walk through how to do it. (at your own risk)

Thanks Steven. I actually also picked up a Tokina 24-70 as well, and waiting for my MTF adapter. I'm buying time to see what other lens options come up at NAB, and what Cine zooms I might dive into.

Any time...
I was thinking: we should probably be fine with out declicking if the lens is used with MTF adapter. As per adapter construction, it regulates Fstop on newer "G" lenses with turning the part of adapter (still don't know how it looks in detail??) that means that iris is working smooth on older lenses as well while F ring is on full open (??). This is only "in theory" as MTF adapter is still not out. I saw before that you ordered it, let us know when it gets to you and your feedback with older Nikons regarding smooth iris...
I my self, I got two Tokinas (28-80, 20-35) and now waiting for camera first and than Birger EOS mount for F (confirmed over the phone by them, as soon as they finish with AF100) so I can use all my "L" primes...

I am with Hunter. I've de-clicked some lenses and there's nothing to it. If you have a clean environment (no, it doesn't require a certified clean-room, just not your barn) you can do it. For me, it's the risk/benefit ratio. If it's a $500 lens, sure I'll do it. If it's a Arri Super Speed, well then...I'd probably send it in.
Maybe I'll start a shop for this...I love lenses and working on them!

Matthew Bennett

Wow, you guys have inspired me!
I'm off to attempt a de-click on my Nikon F mounts this weekend....

Any other advice .... take photos along the way so you can remember where to put everything back, etc..?

I'm also assuming I'll need some of those micro mini screwdrivers, right?

Hunter Hampton
01-14-2011, 08:09 PM
Matthew-

Its so easy bro- its something like this (sorry its been a few years but your a tinkerer, I know you can figure it out):

Look at the rear mount- note its position.

Remove rear mount screws (micro screwdriver), slowly pull the mount off (the aperture linkage that comes out the back may move out of position- dont worry, just remember what side its on)

Pull the actual aperture ring back- either balls will pop out or youll see a small brass thing with a screw or two in it- take that off.

Place the aperture ring back on in the position you found it.

Place the mount back the correct way (again, you may need to twist it a bit to get the aperture linkage to sit properly)

Put screws back in. DONE.

Sound scary (and it is the first time) but its really not complicated at all once you remove those screws. Please share your success once you try it! Everyone needs to know how easy this is.

Matthew -found this (you dont need to do all this stuff of course- this guy was just cleaning the lens):

http://bowdacious-b.blogspot.com/2009/01/disassembling-nikon-lens-series-e-50mm.html

Cant see where the little tab is- should be the same as the other lenses though unless because of its size they had to do it another way.

Matthew Bennett
01-15-2011, 08:59 AM
Complete! Holy smokes it was simple!

The Nikon 50mm 1.8 e-series pancake I worked on had this little mini metal tab thing with the ball built into it, and you could see plastic grooves inside the lens where the click spots were. It was held on by little plastic tabs that weren't screws - so I just ripped it off, basically.

Very simple re-construction, a little cleaning of the sand and crap in the lens, and voila, non-clicked Nikon 50.

I'm off to do my other lenses!

Hunter you're a genius man!!! Thank you!

Matthew Bennett
01-15-2011, 09:02 AM
Now examining the lens again, there's one kind of weird thing, when I put it right at f1.8 wide open, it kind of bounces back a little to f2. I guess the hard click allowed it to sit there firmly, wide open, and now that it's gone, there is a little bounce. It sits at f22 solidly though...

Maybe god is telling me to shoot a little deeper from now on... :)

or RED ! lol

Hunter Hampton
01-15-2011, 12:19 PM
Yay! Glad it worked! The pull from f1.8 to 2 is probably from a small spring next to the aperture that you can take out, but if it doesn't bother you too much, just leave it- most lenses should be fine and not pull.

LeavingTheCandy

A lot of folks use a THICK/CLEAN grease (hi-temp) to dampen the aperture ring so that there's a little more resistance to it. It works like a charm!

Any experience de-clicking Canon FD lenses?

Any experience de-clicking Canon FD lenses?

It's probably the same type of operation..

So all in all this weekend I de-clicked a Nikon 50mm e-series f1.8, a Nikkor 105mm f2.5, a Kiron 28mm f2, and a FILTHY dirty Nikkor 50mm f1.4.

Each lens was REALLY different in it's construction, so I had to be patient and go on a little adventure with each one.

The Nikon 50mm and Nikkor 105mm were as smooth as pie to disassemble. The click mechanism was obvious and fairly easy to remove. It would be nice to dampen the action on the iris, as it is extremely loose and free-flowing now. And probably epoxy a gear on there as well, just for those moments when you want to throw the follow focus on the iris just for fun!

The Kiron 28mm f2, well the iris didn't work in the first place... it seems to only be controlled by the tab in the far rear... I can't make heads or tails of it but at least I managed to de-click it!

The awful dirty 50mm 1.4 Nikkor was very confusing, there were no obvious screws to take off the back, I eventually figured out the lens is it's own little unit unto itself and everything is threaded onto it like a nut to a big bolt. Very unusual given the other Nikkor had such easy access. I managed to declick but the lens itself, including all the interior, is a dirty mess. I think all the grease has been polluted and seized up somehow...
I guess that's for Hunter's advanced class to figure out!

I also tried to do a e-series Nikon 100mm f2.8, which has really hard clicky stops in it, but I stripped one of the tiny screws trying to get the back off. Don't know how to proceed... I'd imagine you'd have to drill the screw out completely and get surgical on it to continue.

Thanks again Hunter for the advice!

Lens repair/modification is steeped in mythology and voodoo much like violin-making. It's just a series of simple, yet demanding steps. My word of advice is to start on a cheap lens or three before your $$ glass and don't open-up a lens that you can't afford to be without.

vcassel
01-18-2011, 11:40 PM
Any links/recommendations on the grease, Hunter? I'm hearing you should always use the specified grease originally used on the lens. Not that I can find that info on old Nikkors...

Matthew Bennett
01-19-2011, 07:39 AM
I'm in serious need of some grease too! I've heard silicon lubricant, lithium grease...

Hunter Hampton
01-19-2011, 08:55 AM
I cant recommend a good grease, i heard of someone using the black component from jbweld, but that sounds sketchy to me. LeavingTheCandy above said he would recommend a hi-temp grease- maybe a good starting point. Maybe he will share a specific brand?

Jason Davenport
01-19-2011, 01:07 PM
Guys I would be very cautious about what kind of grease you are using. They can emit harmful chemicals gases that can get in everywhere and fog every element and can react with the coating. You should just call are qualified lens repair shop and get real recommendations.

Hunter Hampton

I was recomended this just now by a lens tech: http://www.amazon.com/Permatex-80345-White-Lithium-Lube/dp/B000HBNV58/ref=pd_sxp_grid_pt_1_1

Maybe try a small dot on your least favorite lens and see if it does the trick.

A few months ago, I was interested in decklicking my FD lenses, but I was not so brave, but I found this link:

This guy has a video tutorial, he uses the steel component from JB weld, that is like a grease.
Good Luck!

Anyone has tried de-cklicking any Zeiss ZF's?
Would love to know how... if possible!

As Hunter stated and I humbly found out, it's a pretty simple mechanism inside the lens which creates the 'click stop'. There is often a very small ball on a tab underneath the aperture ring, that keys into tiny grooves cut into the plastic or metal. Very easy to remove without any headache.

My suggestion for the ZF's is to just find someone's photos that took one apart (I found tonnes of lens deconstruction photos on flickr.com)

Follow those photos as far as getting off the aperture ring (usually the first and easiest component to remove), and the proceed to root out and remove the clicker... should be easy, but don't quote me on it...

Matthew Bennett
01-19-2011, 06:59 PM

Okay, I found the rear of a ZF, and it looks very similar to the 'easy as pie' Nikon e-series lenses I took apart.

You'll see three small screws on the back, take them off with a mini star-head screwdriver. The metal part will pop off. Once that part pops off, it will release the aperture ring to be able to be removed. The aperture ring may be held on by a small screw or two, so take that off as well. Get the aperture ring off, and it will become obvious very quickly that there is small ball or small tab with a ball which creates the 'clicks'. It will probably be either screwed on with ultra tiny screws or there will be some way to rip it off very easily without damaging any thing.

Take it off, re-assemble, and you're good to go.

Rear of ZF: ignore the red circle, it's from someone else's instructions, I'm just referencing those three rear screws....

And also re-read Hunter's instructions 'cause he said it all better than me!
