Best Contax/Yashica to EOS Adapter

[Andreq]

Hi,

I have 3 contax/yashica mount lens that I'd like to adapt to my Canon t2i (550d).

I got a cheap eBay adapter and I'm not satisfied with it. Once the lens is mounted on the adapter, it "wiggle" a little, its not as stiff as a m42 adapter. It's not so bad I can't use it, but I'd like something more rigid.

Is there any better adapter/seller on eBay that you know about ?

Thanks


p.s. I didn't knew where to post this... I guessed this was related to MF lenses.

Tried many, they all wiggle a bit.
Not a problem with small lenses, but with big heavy lenses can be a problem
(my 2/135 fell once)
Only way to have a totally safe mount is to add the Leitax extension www.leitax.com
note: only possible for MM lenses.

The best ones I've had have been black and cost about £30-35 if it helps! But they seem to change all the time!

I have one from Big_is it doesn't wiggle buy it also allows focus past infinity as it's a bit too thin.

Thanks all!

Those Leitax mount looks create, but I can't see myself spending that much just for a simple wiggle. I could probably do something similar using my current mount.

I currently have a big_is adapter (chrome/aluminium color)... I'll see if I can talk with "him" (it?) on eBay to get a proper one.

I should have googled first!

The trick about the slot "widening" is quite good. That's enough to make the fit a bit tighter and way less wiggly.

I finally was able to buy Leitax adapters for all my C/Y lenses. I have a big job coming up and want to feel comfortable and not worry about my precious lenses wiggling or even falling of my camera.
It now feels as if I have a completely new set of lenses. The way they fit on the Canon is incredible. No play whatsoever. Tight as if the camera and lens are cast from a solid block of metal.
Until now I was always worried about the other other adapters and always had one hand on the lens just in case. It also improves my shooting because focussing is so much more precise.
I have no stocks in David's company and get no benefits but I can really advise you to get the Leitax adapters.
Maybe someone can organise a group buy and get a nice discount.

The 100-300 and the MP 100/2.8 cannot be Leitaxed because the screws are in a different place as the other Contaxes. But I have had a machine shop drill a couple more holes though and they now fit perfectly.

May not be the best but some of the member here are satisfied with this one.

Can anybody else confirm that this is good to buy? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=251150935437

Btw, I've bought yet another adapter from Big_is

This one was better than my first C/Y adapter. I did the little adjustment found on my third post and it's perfect.

I didn't see any problem with infinity focus but I might have to test it more.

because I have great success with Big_IS adapter, I have purchase another one for my contax. Hopefully it'll be good.

Just have found out this:
PLS READ TO THE END-the solution is at the end.
certain adapters are really not focussing to infinity BUT
is more likely lenses are not calibrated or are decalibrated(worn out) not focussing to infinity.
Have just tested many zeiss and sigma 28/1.8 aspherical high speed wide multicoated.
Some zeiss will never focus to infinity even with adapter which set set to infinity with calibrated lens.

I have got two new adapters after there were the very well known lens-locker-problem. Both without chip-one can let it be chipped by leitax(he has dandelion and optixpcb v7(newest) but will mount also other chips.
1. First i tested only lens-mounting and not infinity on both of these(name will follow below). its working sometimes(on certain lenses) but on some afterwork must be done. if lens-locker-hole is worn out use a fine file and file down/flat a bit the left side wall where the locker-blade is engaging. With edge of the file file a tiny cut into the corner so the blade can engage when needed. maybe it must bent inwards a bit.
the problems of these lens-locker-blades are:
a) too thin, not stiff enough, not hardened
b) thick enough but but not hardened. one has to bend them in all the time and they will break. happened with the peleng8 one which has 0.44mm approx. thin ones are 0.22mm.
2. chipped adapters. if adapters have too much play(it depends chip) signal maybe be disengaged-get lost. avoid optixpcb-adapter with chip. but i also have two m42-eos which only one is working properly, maybe chip is not positioned precisely.

3. INFINITY
I have DSLRExchange-adapter(the only one with screws) which was made to clear mirror on certain FFs DLSR like EOS 5D and 6D models.
After having huge lens-locking-problems i bought two new unchipped-adapters.
These are:
K+F CONCEPT (pls remember this one very well since its the only one which i can advise) its focussing past infinity and with this overrules decalibrated lenses. Let chip added by LEITAX. send him chips which he does not have in stock or let it be sent to him. beside dandelion and optixpcb v7(newest) there are EMF and one more chinese chip(see his page). simplest programming is optixpcb-chip and most sophisticated.
Second adapter which holds lenses perfectly BUT DOES NOT FOCUS TO INFINITY some zeiss and sigma 28/1.8 i mentioned above, its this one:
ebay #371148184919
cenyonline
elec-mall
(ecamcity)
Characteristic of this adapter is that lenses are very tightly fitted. with sigma its so tight(no play at all) that i can hardly remove it when not pressing lens to base. and lens-locker must be bent in to avoid disengaging when removing from camera.
LEITAX told me to recalibrate lenses myself. search in google.

So best adapter is the one from K+F CONCEPT(have not found the producer itsself)

Important note about Optixpcb chipped adapter:
The ring they use on more expensive highprecision is not advised to get: dont buy it at all:
lenses may fall off. its the same thin non hardened blade which is used on cheapest noname-adapter which i already have.....But even if its holding certain lenses only a bit of play will disengage signal. this did not happed on any other dandelion and EMF-adapters. i also have a M42-EOS which has that problem, second one is ok. So better letting leitax mounting chips.
will now try to find infinity-focus-adjustments-tips.

[europanorama]

Leitax now also have rings for certain-not all AE-lenses. But they must be adjusted to infinity anyhow.
Leitax just told me they will make them as thin as possible.
Pls check there site also for new C/Y-NEX-adapter and how new ring is added ONTOP of C/Y-lenses.
