i am trying to find out whether this will fit onto an m42 to eos adapter-he is charging between 62 to 65 euros including post.

here is the link to FM which shows what it looks like:



ziggy,we are almost in the magical land of focus confirmation!

Greg,

Interestingly, I found this same guy on the Italian EBay.

http://cgi.ebay.it/Canon-EOS-Autofoc...QQcmdZViewItem

I'm not really very good with Italian, but it looks like he had 15 units for sale, and sold out quickly. I do like the new version in that it's a black circuit board, and some folks said more durable, and it appears to be gold plated contacts.

I sent the person an e-mail asking to be informed the next time he has inventory. I'll let you know if they respond.

Thanks,

ziggy53

hi ziggy

i have received a response,and looking at the distribution list he sent you the same email-i doubt there are any other ziggy 53's out there...you should probably get yours soon.

the boys in the manual focus forum are very excited!

Hi!
Price for a Chip + S&H is 62 EUR if you pay using moneybookers.com with your
credit card or bank account or 65 EUR if you use PayPal (I can not accept
credit card payments through PayPal).
my email is the same for both payment systems:

Ciao
Matvey
P.S. Please do not forget to specify your correct shipping address

I'm confused (read ignorant)- just what is this and what will it accomplish?

Greg,

I haven't gotten anything yet. You're the lucky one!

Greg and I, and others, like using "old glass" occasionally on our modern digital-SLRs. The reasons for doing this are many and varied, and often have to do with the economics of new vs old. The quality of much of the "old glass" is quite good.

The problem is that we have to use an adapter to mount our old lenses to the camera. The adapter/lens combination is not able to relay any information about the lens, since there is no electrical connection to the camera.

Exposure is no problem, since we can use the on-camera exposure system in either aperture priority or full manual, and the camera will continue to function, almost as though there was a "coupled" lens in manual mode.

The main problem is the focus system. Some cameras allow the autofocus system to "confirm" focus, even with uncoupled lenses, Canons do not. We are left to focus the lens manually using the ground glass in the viewfinder, which is difficult, to say the least.

What this new "chip" allows is the operation of the focus confirmation part of the autofocus system, as though there were a "coupled" lens in manual focus mode. It does this by "faking" the signals of an actual lens, were it attached.

There is still no actual coupling of the lens, but the autofocus is "brought to life" enough to allow the camera to help with focussing.

Not that I have a 5d ,nor will I for quite some time yet,so its not an issue for me,but there are now some m42,and other mount, adapter plates coming on line which will allow manual lenses to be fitted on the 5d.

The problem they appear to have overcome is the 5d's large mirror hitting the adapters-so all you 5d owners will soon be able to take advantage of Zeiss,Zeiss-Jena,Contax-Zeiss,Pentax and possibly others such as Leica.

bloody expensive thing it is. but alas, I MUST GET ONE!!! lol

This puzzles me. I have a M42 to EOS adapter that is a simple plate which was purchased many years ago for the EOS 620 film camera. Being film that camera is, of course, full frame. I had no problems with it. So, why does the 5D need something different?

My budget is such that I am not about to buy a 5D. I am ejoying the fact that it works on the used D60 that I bought late last summer. The lens I use it with are not of the Jena, Contax-Zeiss, quality but I am getting some fun out of them anyway.
Jane B.

I think its due to the mirror on the 5d hitting the adapter and/ or the back of the lens.

the 5d mirror is larger than usual-if you get a 5d its worth gently trying out your adapter plate-it may work but others have found out it may not

i understand that not all lenses foul the mirror but others do.

which m42 lenses are you using?

Pretty much no name compared to what brands are bantied about here. I have:
Vivitar 55mm 2.8 that came with my first film SLR.
Mamiya/Sekor 55mm 1.8 purchased used in the 1970s from a family friend that owned a camera shop (the shop is long since closed and he has died.)
Vivitar 200mm 3.5 from the same source as the Mamiya/Sekor but purchased new also in the 1970's.

My lone EOS lens is the original 28-70 3.5-4.5 from 1988. Purchased at same time as EOS 620 film SLR. Adam T who seems to be very well regarded on dpreview made the comment that those first EOS lens had to be good as they were depending on them to establish the new mount. Found the exact quote "I've NEVER seen a Mk1 , every one I've heard of has been a Mk2 and they're very sharp as is the old 35-105 F3.5-4.5 Pump Zoom.. I suppose that being Pre-L (for EOS) and the only zooms in their focal lengths, they HAD to be !"

Of the M42s the 200 is the one I have used the most. Turned out great for hot air balloons. We have a Balloon Fest every August and when the wind direction is right they often come right over my house; although, the park the Fest in is is just a few blocks away.

The seller showed up again.

It did cost more than I expected, but not too much more.

Remembered I could post a pic here without an account with a hosting service after I wrote the above.

I think this is with the 200mm Vivitar mentioned above. I don't know how I could read data for original file to tell. But, if it is, seems worth putting up with manual focus and aperture setting to me.
Jane

Jane,

That looks great to me! Manual everything is how I learned photography.

One more seller showed up here US http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7627282399&rd=1&sspage name=STRK%3AMESE%3AIT&rd=1
With even better price for shipping, $7 within US…
I will buy...before he did not mark up the price...

I am interested in your experience with him as a seller and how the chip works out when you get it

I still haven't heard anything from the seller. My payment was accepted immediately. Should I be getting concerned?

I would send him some PM and see if he responds. If not, then it is probably time to EBay involved. 2 weeks is, I would think, just a little long to wait without hearing anything.

While Scott was responding, I was typing a simple query to the seller via EBay. He responded the same day and gave me the USPS tracking number. I checked the number, via the USPS online tracking system, and found that the PO tried to deliver the package on June 14 and left a notice.

Since I never found a notice in my mail, I called the local PO with the tracking number and delivery information. The person I talked to confirmed that the package was still there. I went to the local PO and retrieved the package this morning.

WooHoo, it's here, it's here.

The package included the chip, carefully packaged, and a single sheet template, with 5 copies of the template printed on the sheet, but no real instructions.

At first, I tried mounting the M42/EOS adapter on the camera, and inserting the chip into position between. I read where another person did this and it worked fairly well for them. I rapidly dismissed this as impractical and potentially damaging to the contact pins on the camera, although I didn't try too many different methods of attack.

I was not too keen on the templates, and I didn't feel that they explained the orientation and placement of the chip on the adapter sufficiently.

I wound up putting the adapter on the camera, without a lens, and marking the position of the pins relative to the adapter using a fine-pont marker. This seemed to give me a much better idea for orienting and mounting the chip correctly. I repeated this operation to guarantee I properly mounted and aligned the adapter.

Using both the template, which got me close, and my markings, which I believe are more definitive, I felt confident to proceed.

After a few anxious moments playing with the super-glue, the deed was done. No turning back now ('cause that sucker was on to stay.)

I mounted the adapter with chip onto the camera, visually confirmed that it "looked" correct, and fired up the camera.

Voila! The camera showed f1.4 with no lens attached, as it should because the chip is sending information to the camera, just as though there was a lens.

I mounted the Vivitar 500mm, f6.3, onto the adapter, and checked for focus confirmation. A little touchy but yes, it works!

I went outside and popped off a few hand-held shots of the utility pole and some fixtures. It's working pretty well.

Samples later.

Glad it arrived and thanks for your description of fitting the chip.

A few questions..

What do you mean about it being a little touchy?

Did you mount it on a cameraquest adapter?

Do you get a beep as well as the focus confirm light?

I am getting good results with the KatzEye focussing screen but once Summer returns down here I may get one for my bats in flight shots.

How I was able to get anything in focus before now is a mystery..

Once you have had a chance to give it a real test I would be interested to know how fast the confirmation is when tracking moving subjects.
