Canon EOS 6D and manual lenses

It's like with any other manual lens on a Canon camera - you set the aperture on the lens and blades stop down straight away. The camera has no way of doing this itself as Canon cameras only communicate using electronics, which a manual lens doesn't have.

So for example...

1. Set the lens to f/8 (the blades close down straight away)
2. Manually focus the lens (note that the more you stop down, the darker the viewfinder becomes)
3. Shoot

The other way of doing it is:

1. Set the lens to wide open e.g. f/1.4
2. Manually focus the lens
3. Set the lens to f/8 and shoot

Hope this helps.

by the way if you would like to shoot in aperture priority mode , will the camera through the ttl exposimeter tell you the right exposure ?
my answer is yes but you can certainly tell me more precise ...
thanks

Yes, the camera will be able to tell you the correct exposure in A mode. However, from what I read and my own experience when your aperture is small maybe f11 the metering is not spot on so you might have to compensate a bit. The thing is, this 'small aperture' is lens dependent so difficult to give a general figure when this starts

First test shot wide open with Olympus OM 24mm f/2.8 on Canon 6D, sweet...

Hi all

Just joined the forum

I have the Tak 35mm F3.5 on a Canon 6D and yes it does hit the mirror at infinity

So I used 2 small slivers of printing paper and placed them between the adaptor and the lens flange.

Now its not hitting the mirror and judging by the test photos focus at infinity is correct as aligned on the scale

The tolerance between hitting the mirror and not is miniscule I judge it about a 3rd of a millimetre

Glad to help tromboads

I am using this adaptor for all my Pentax Tak lenses

http://www.amazon.co.uk/gp/product/B008H2I1M2/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1

I have bought one for each of the Tak lenses I have (many) and they all work really well 9 out of 10 times when you get the green disc focus is correct of course just keep the lens at wide open then stop down in good light, you can actually work this adaptor at mid range apertures in good light quite impressed with this adaptor considering the low cost

I knew there would be a problem with the 35mm but I also knew not all full frame Canons had an issue so I guessed it was a small tolerance problem and not something you had to get a grinder on to.

Lets face it if you have to grind down part of a lens to get it working don't buy that lens for your camera....!

Put a wee piece of paper on each side of the lens flange then screw on the adaptor

Take my word for it works and you get a real class lens working on a full frame canon 6D not sure about the 5D versions though but I expect the tolerances are nearly similar just experiment with different thicknesses of paper till you get the mirror clicking stop free.

The thinner the paper that gets the mirror working the better of course

super takumar 50 1.4 hits the mirror on my 6D


PostPosted: Tue Apr 29, 2014 12:46 am    Post subject: ThX Reply with quote

Thank you so very much for posting info on the Canon 6D and C/Y Zeiss lenses. I have been sweating bullets before my 6D arrives from B&H. Those are what I use the most for video and cinematography set ups. I was so concerned that I checked everywhere for new adapter types, like from Leitax, Fotodiox, Kindai, and others. I'm using the general purpose Fotodiox ones and they been fine for my 60D, but the 6D -being full frame- concerns me. The clearance was an issue on the mkII, and I panicked for this new 6D, but all is well I think. Thx.

I've updated my original list with my own findings. Will add others' findings to it when I have a bit more time Smile

Hi, my Super-Multi-Coated Takumar 50/1.4 hit the mirror on my 6D focusing to infinity (tested with 2 adapters with and without af confirm chip).
Now I'm looking for a good adapter for my BIOTAR 2/58 with exakta mount.

When you say "mirror hits", are you destroying a 6D mirror each time? The reason I am asking is because I am not sure what to expect. I just bought a K Pk mount for EOS from China, and the stock Pentax K-1000 lens did not work with this adapter on my 6D. The frame was half-way closed in the resulting image. The mirror didn't appear to be broken, though. The adapter didn't really work, however, unless I am doing something wrong.

Well my mirror is still in one piece Laughing

Very Happy So, the mirror doesn't shatter if it has something in the way? I just bought a nice, cheap Vivitar 75-205mm 1:3.8 lens on eBay. It's somewhat heavy, but very slim at the same time. The glass seems to be nice and it definitely works on the 6D. It has a manual aperture setting, so you different kinds of M42 adapters will work on it. I didn't read the full thread, but you guys probably discussed the fact that there are two types of M42 adapters. One is with a very wide rear opening that doesn't cover the aperture pin:

There is also one with a much smaller rear opening diameter, and it does cover the aperture pin and locks it in manual setting:

Mir-1 Grand Prix Brussel 1958 37/2.8 - hits mirror at infinity


I modified my copy of this lens in order to avoid it hitting the mirror at infinity. On my copy, and I don't know if this applies to all versions of this lens, there's a small semi-circle of metal in the rear end of the lens. It is this metal piece which cause the problem. I simply removed it because it seems to have no function now - perhaps it's for protection or was needed to fit older film cameras? Well, I took a small size screwdriver and used it to carve a thin line digging just about half way through the metal. This procedure made it possible to peel of the metal piece using a pair of tongs by carefully spinning the metal around the tongs.

This used to be one of my favourite manual lenses but I was rather disappointed by the results from the 6D. The far edges seemed noticeabe softer than on my APS-C camera.

ManualFocus-G, can you please reply with your experience. Are you really saying that the mirror won't break when it strikes protruding lens parts?

My camera has hit several lenses with no damage. However, I've never tried using a lens which is obviously sticking out much past the adapter.

Got my 6D today and here are my first reports on this topic:

C/Y Planar 50/1.4 MMJ with a cheap adapter( this one - Click here to see on Ebay) is OK.
Helios 44-2 - MMZ zebra version - prod. 1971-1972 AFAIK is OK.
Zenitar-M 1,7/50 is OK

And here goes my big disappointment:

MC ГЕЛИОС 44-3 (HELIOS 44-3) - prod. 1990(90**** serial) hits the mirror

Well yes, but I wanted it so badly and finally got it a day before the camera, at a decent price, in great condition - looks like new, feels like new and didn't have a chance to give it a proper shoot.
Anyway maybe I'll give it a shave - I guess about 0.1-0.15mm will be enough.

Another two:

PANCOLAR auto 1,8/50 MC - serial 108***** hits the mirror.

Helios 44-2 - Valdai - serial 89**** serial is OK.

Hi gentlemen!
I have a 6D and I have a Zeiss Ultron 50 1.8 BM.

Does the lens hit the mirror? Do yo have an idea regarding on a good adapter?

Thanks a lot!

Hello!

I just got a C/Y Yashica 55mm f1.2 lens and it works great on Canon 6D!
I used this C/Y-eos adapter https://kameratori.fi/-cy---canon-eos (in Finnish). The C/Y-adapter is a bit loose and have to put few small tape pieces between lens and adapter. A quick and dirty solution, but it seems to work.

hi,

For what is worth, some extra data point for 6D combination:

Works for me
Leitz-R 90/2
OM 21/2
OM 55/1.2
CV 125/2.5
CZ 35-70/3.4

Does not work for me Crying or Very sad
SMC A 50/1.2 - it stills has the pin, so 100% does not work; only works on the 350XT
Rokkor 58/1.2(metal focus ring version), 58/1.4 - both can be used for upto about 15 -20 ft, works full range on the 7D

Cheers,

LEITZ WETZLAR ELMARIT-R 1:2.8/90 - Serial 1965*** is OK.
