July 29,2013 update: I've switched my worldwide shipping service from all Canada Post to all FedEx Priority because too many international shipments were taking 4 weeks or more to get delivered.  I sent a package on Friday to Germany by FedEx Priority, the usual slowest international destination besides Russia and it arrived on Monday so only 1 business day instead of the normal 4-5 weeks so it is worth the switch.

June 23,2013 update: I will no longer be including a rear lens cap or any screwdrivers with my kits anymore.  The reasons for not including caps are the standard EOS caps are too tall to send in letter mail and I am told the reason there is often a delay in international customers getting the kits is that the extra thickness is causing jams in automatic letter sorting equipment and extra customs attention.  For a while now I have been sending wooden rear lens caps that are less tall but they take as long for me to machine as the adapter and this is really slowing down my limited production time on my personal garage vertical CNC mill.  Plus the wood makes a real mess of my garage and quickly causes a fire hazard with all the dust.  The reason I am dropping the screwdrivers is that the small inexpensive ones I have been sending with some kits are not very good, this causes a greater risk of screw heads stripping than using a high quality larger grip phillips 0 or 00 drivers that can be found at any worldwide local hardware store.  A larger grip allows more downwards force to be applied which is very important in minimizing screw head damage.  Another reason I am dropping the small sharp screwdrivers is that I think it will again help minimize customs inspection slow downs and reduce risks of package damage.  I am sorry for any inconvenience this causes anyone but I am just trying to put my limited time and focus on developing and producing the highest quality EOS conversion kits I can and help make sure they can arrive to my worldwide customers as safely and quickly as possible.

April 2013 update.  I have removed the youtube videos showing how to calibrate the large white super telephoto lenses and no longer recommend you performing the calibration yourselves after one customer managed to damage their lens causing me to have to replace it with my own personal 400mm 2.8.  The adapter is still very useful on the 300/2.8, 400/2.8 and 500/4.5 lenses without calibration, you will not reach infinity but for many normal uses like bird photos and portraits the ranges are still better than any other adapter solution. For those of you wanting infinity you can get in touch with Eddie Houston (The Lens Doctor) in the UK or Jim Buchanan in the USA who carry my adapters and perform lens calibration and service work directly.

The long awaited replacement to the EdMika 0.75mm EF-FD glassless brass adapter is finally here!  I personally am proud to announce the heavily re-engineered 0.5mm FD-EOS (nFD, FD, FL)-(EF,EF-S) dual-orientation glassless brass adapter.  This is exactly what you need to take your white FD super telephoto lens and achieve original lens performance on your Canon DSLR camera.  It will also bring the greatest focus distance from any other FD lens by minimizing the lens to sensor distance, effectively placing it at 44.5mm.  In fact, I could make the claim that the adapter places the lens at 44.3mm since I found a way to squeeze an extra 0.2mm out of the original FD mount design by tightening tolerances and reducing a critical undercut dimension.

Why dual orientation / bi-rotational?  The extreme closeness this adapter gives you puts all aperture trigger levers into a contact position with areas of full frame and 1.3 crop bodies (but not 1.6 crop bodies such as the 7D/60D/rebel.    The old 0.75mm adapter also created a contact condition and people using full frame/1.3crop bodies were grinding down the aperture levers or living with getting marks on the plastic area near the electrical pin contacts.  By allowing the adapter to be mounted 90 degrees counter-clockwise from normal position, the aperture lever can be moved into an area where this contact condition does not happen.  So why did I make the adapter also work in the normal orientation as well?  All the white super telephoto FD lenses (The FD 200mm 2.0L, FD 300mm 2.8L, FD 400mm 2.8L, FD 500mm 4.5L, FD 600mm 4.5 and FD 800mm 5.6L) have a rectangular area near the back to make room for the complex larger aperture lever mechanism that causes vignetting (darkened corners) on full frame sensors. This darkened corner condition can be fixed easily in Lightroom/Aperture/Photoshop but some people may still not want to be bothered with post process fixes.  For these people we added a secondary notch at the end of the aperture holder mechanism in the normal orientation so that they can bend the lens aperture lever inward enough to prevent the contact condition.  I am not a fan of permanent modification, and bending a lever is more reversible when compared to grinding it down.  Those lucky 1D series 1.3 crop owners need not worry and just enjoy the rotated adapter position without any darkening issues in the corners because of the slight crop and the 1.6 crop body shooters can do whatever they want since either orientation works perfect and does no damage.  The only compromise in this dual FD side orientation adapter solution is that for the older silver twist ring mounts you will have to use your thumbnail or FD lens cap to trigger the twist release mechanism since this new hybrid EdMika FD-mount no longer triggers the release itself.

The adapter can also be used with shorter focal lengths but focusable distances drop below arguably useful levels under 200mm focal lengths except for macro lens shooting. For people wanting to make use of some of the wonderful vintage Canon glass of shorter focal lengths I highly recommend the Sony NEX system with a 1.5 crop factor (vs. micro 4/3rds 2x crop) until a full frame mirror-less body comes out.  The NEX also does quite well with the longest super telephoto lenses apart from looking like a glorified lens cap on them but the 1D4, 7D put it to shame image quality and resolution wise in most shooting conditions.

We now make these adapters 100% ourselves using a very high precision vertical cnc mill, lathe and cut-off-bandsaw at my father-in-law's garage in a small town an hour north of Toronto Canada.  This gives us the time we need to tweak our development process instead of the few hours we were given before by machine shops we had used in the past. This awesome FD-EOS 0.5mm dual-position adapter solution is really is pushing the limits in just about any way you care to imagine because of this flexibility we have.  

As always my brass adapters are machined from a single solid puck of 360 grade brass. Why solid, uncoated Brass?  Because Brass is softer than your camera flange and your vintage FD/FL lens promising not to damage your precious gear in any way but still strong enough to hold on through even heavy abuse.   Because with Brass we can maintain higher tolerances by not having to add the thickness variability of a coating process and because glue holding reporting chips holds well to bare metal but bonds poorly to coatings.  Brass is really beautiful to work with and worth the material expense.

My adapters continue to come standard with a Gen4 programmable Dandelion chip to give accurate EXIF data reporting, proper metering and some AF confirmation assistance although in practice the eye (especially using a proper focusing screen) or live view is the most accurate method.  Please note that know issues with these chips is an occasional loss of signal which can affect proper metering for a moment that can cause a lightness spike in a video but this is only limited to the 7D body as far as I can tell.  To overcome you can shoot video in manual or tape over the chip contacts.  If you wish to buy any of my adapters without a chip to use them bare or to glue on your own favourite chip brand, just make the note "no chip" on your paypal purchase and I will refund you 10 dollars and send the adapter without a chip.

FD 85mm 1.2, 5 feet / 1.5 meters (I recommend the FDn mount swap kit for this lens instead to get infinity)

FD 150-600mm 4.5L  6meters at 150mm and close to or meeting infinity at 600mm

FD 200mm 2.8, 25 feet / 7.5 meters ( I recommend the FDn mount swap kit for this lens instead to get infinity)

FD 200mm 1.8, unknown

Question & AnswerAnswered On
Q: i bought some time ago a 0,75 mm Adapter and its fine !!! No i got a Canon FD 500 l. Can you sent me a instruction how to calibrate this lens ? kind regards14-Feb-13
A: The exact same method I show here http://www.youtube.com/watch?v=Ytgt1d1Ts8I
Q: So what you're saying is, I can use this kit on my 200 2.8 S.S.C.?12-Feb-13
A: You could but its not going to get you more than about 20 feet of focusing distance. I'm working on a mount swap kit for most older FD silver ring mount lenses over the next 4 months.
Q: Dear , thank you for your great job. I have a canon 5D mk III and a canon 500L FDnew. I'd like to convert it on EOS. I understood that, for sure, by an internal focus adjustment, I can get infinity focus. I'd like to know if there is chance to get infinity just by your adaptor without to open the lens (as the 600L). I have even a 50-300L FD and a 300 FD 2,8 Fluorite. Did you produce the right adaptor? Once mount the EdMika adaptor the Canon EF 1,4X mk III is working ? I think on 500L FDnew for sure, no idea on the others. thank you,.10-Feb-13
A: Thanks, the 500L can only be made to focus to infinity with the focus element calibration combined with my 0.5mm FD-EOS adapter. I so far have not been able to develop a mount swap kit to make it do it without calibration since the auto-aperture control lever stays fixed in the lens with the old mount removal and to take it out is very hard. With the 0.5mm adapter you still can use FD extenders, just mount them to the lens first then put the 0.5 adapter on them. The flourite 300 I have not tested with the 0.5 so I don't know how to calibrate it (or how hard it would be). I am about to launch a mount swap kit (all mount swap kits give infinity without having the open the lens up to do focus calibration) for your 50-300 L including the following FDn 100mm f/4 Macro FDn 200mm f/4 Macro FDn 300mm f/4L FDn 400mm f/4.5 FDn 50-300L FDn 200/2.8 (EdShield/EdLink redesign) FDn 135/2 (EdShield/EdLink redesign) FDn 20mm and 15 fish (EdLink redesign) FDn 17/4,24/2,28/2,35/2,50/4,85/1.8 (EdLink redesign) FDn 85L (EdLink redesign FDn 35-105/3.5 FDn 20-35L FDn 14L (EdLink redesign) FDn 50/1.2 (EdLink redesign) FDn 50/1.2L (EdLink redesign) FDn 100/2 (EdLink/EdShield redesign) FDn 85-300 FDn 85/2.8 SF FDn 35-70/4 AF FDn 80-200L FD 85mm 1.2 Aspherical
Q: Ed, I purchased one of your adapters (Ebay #170764195949) a little over a year ago. It is the 0.5mm thick model, very similar to what you are currently selling. The only difference I see in your current offering are some additional notches in the EOS side face. I have been using it successfully with a 300mm f/2.8 FDn. The question is I would potentially like to buy an older FD lens 500mm f/4.5 that has the chrome lock ring, which I believe preceeded the "new" all black FD mount. I see conflicting answers in your Q&A, one explicitly says no old FD, others say yes. Would the adapter I purchased from you a year ago work on this older lens? Please advise. And thanks for a great product!04-Feb-13
A: There was a series of adapters I sold for a short while that were not compatible with the older style FD mount lenses (and they where advertised as such and discounted to 99 dollars). I only sold about 20 of them before deciding to scrap the series. So most of the 0.5 and 0.75mm adapters out there should work.
Q: Can you replace the metabones speed booster (EF-E mount) front EF mount? Change the EF mount to FD mount ?I want to order one!28-Jan-13
A: I have no idea what you are talking about, but it sounds very interesting so I will investigate it further.
Q: Hi Ed, I know this has probably been answered in the past, however I cannot find a definitive answer so I am going to ask you personally. I have a chance to buy a Canon FD 400mm 1:2.8 L and I own a 5D MkIII. Is it possible to achieve infinity focus on with the Canon FD 400mm 1:2.8 L on the MK III (without any damage to the camera) Your answer not only will determine if I buy the lens, but it will also sell one of your fine adapters. Thanks for your time, I look forward to your answer and hope to hear back very soon. L17-Jan-13
A: Yes. No bending of lever or mounting sideways is necessary with the 5D3 to use the 0.5mm FD-EOS design with the 400 2.8 L and infinity is achievable with the lens calibration shown on YouTube.
Q: Hi, I have an reflex 500mm which Has no rubber focus ring. The ring is made of a tough hard plastic which I cannot remove to take a screw out. Can I reach infinity with your adapter? Camera is EOS 5 D. Renards, Paul08-Jan-13
A: The ring is a hard rubbery plastic and you definitely can remove it. The key is to just pry it up a tiny bit with a small flat screwdriver and push it up on the ledge so it can slip out of the way. It reinstall it just push it back on and I generally don't add any contact cement since the ring reshrinks to a tight fit within a few hours. A few spots of double sided tape like carpet tape is also good to prevent it from slipping after. If you don't remove the flathead screw closest to the infinity marking you will not be able to focus to infinity.
Q: Ed, thanks for continuing to create innovative, quality products. A question regarding FD (breech lock, silver ring) and newFD (nFD). You have been quite clear that your adapters only work with nFD--I get it. However, is it possible or have you thought about adapters for "old/original" FD perhaps that would not be easily reversed (converting back to FD mount)? Basically I got into Canon quite early and all my FD lenses are oFD. Thanks and have a Happy New Year. ...Ric27-Dec-12
A: I'm working on it. My goal before 2013 is up is to have EOS kits for every Canon lens ever made.
Q: Canon 300 mm L F4 FD Please I need to know if you make an adapter to use this lens in a Canon Mark IV26-Dec-12
A: I replied earlier, not yet - see below Dear victor1720, Sorry, not yet but it will with the development of long EdLinks which I am currently working on. - ed_mika
Q: Hi, Will this adapter work with the Canon FD 300mm 2.8 S.S.C. Fluorite, the black one? Thanks20-Dec-12
A: It will fit but I am unaware how far it will focus and if its possible to calibrated the lens focal element to get it to reach infinity.
Q: Hi can this be use with the Canon FD 300 2.8L lens with the EOS1dsMK3 to Infinty Focus? thank you07-Dec-12
A: Yes it can if you follow my YouTube focus element calibration instructions.
Q: works the apapter with my Canon FD 800mm f5.6 S.S.C. (not FD 800mm L)? best regards28-Nov-12
A: It will work but no guarantee of infinity focus, I have heard that some reach it and some don't but if not infinity then very close. The reason is that there is no easy to remove stop screw like in the L version. I don't have a copy of this lens myself so I have not had a chance to evaluate if there are other methods of calibrating focus lens position to allow infinity in all cases.
Q: Hi, Do you charge GST for Alberta buyer? Also do you do combine shipment? Thanks.18-Nov-12
A: eBay only gives me the option to charge the 13% HST to Ontario buyers so no. I combine shipments by giving partial refunds of the shipment portion of any additional adapters purchased.
Q: Ed - I have a new FD model 200mm f2.8, and an EOS Rebel XS also known as the 1000D; will this work with this configuration? Thanks, Rich13-Nov-12
A: There are two FDn versions of the 200mm 2.8 lens, the newer one works with this kit, http://www.ebay.ca/itm/EdMika-Canon-FDn-EOS-adapter-kit-14mm-15mm-17mm-24mm-28mm-35mm-50mm-100mm-135mm-/170911278282?pt=US_Lens_Adapters_Mounts_Tubes&hash=item27cb1b24ca&_uhb=1#ht_2184wt_1413 and the other does not. You can tell the versions apart by closest focus distance. If your lens says 1.5 you are ok, if it is 1.8 you cannot use this kit yet as it will require a longer EdLink. The 0.5mm FD-EOS adapter will only get about 15-20 feet out of the 200mm 2.8 series of lenses, ok for portraits but fairly limiting.
Q: Can you please tell me if this adapter will work with an FD 400mm F4.5 (older silver ring adapter) and allow me to use it on my T3i?12-Nov-12
A: Yes it will and can reach infinity if you follow these instructions: 1.Slide the built-in hood forward to make room to work on the rubber grip. 2.Use an awl or an icepick-type tool to gently break the glue that holds the rubber grip to the barrel. Work the tool underneath the entire grip, and stretch the rubber until you have enough slack to gently slide the grip forward over the retaining ridge on the barrel. 3.Slide the grip forward until you uncover the round screwhead directly forward of the infinity mark on the barrel. This screw is the infinity stop that must be unscrewed. 4.Use a flat-blade screwdriver to back the screw out of its hole until the barrel is able to turn past the infinity stop position. You don't need to remove the screw; just back it out and leave it there so it won't get lost! It will also keep crud from entering thru the screwhole. 5.Slide the grip back into place so it covers up the screw. It will shrink back to its original size; so you probably won't need to glue it back in position with contact cement. 6.Attach your Ed Mika converter, and enjoy infinity focus with the Mirror Lens on your EOS! 7.Be careful not to turn the barrel too far past the infinity position; the stop is no longer there to protect the innards of the lens from damage!
Q: Hi , I have one more question. How the adapter is connected/fixed to the lens ? By means of screws ? I case these screws are supplied with the adapter ? Many thanks in advance fro any info. Regards, Paolo07-Nov-12
A: The 0.5mm adapter is the only one that I have that attaches to the lens the same way an old FD mount camera does (apart from having to trigger the ring release on the older breech lock due to the modified FD body mount design on my adapter that allows 90 degree offset).
