Lenses / Re: Canon FD to EOS Adaptation
« on: April 14, 2014, 04:05:29 PM »
You can use the same adapter that you use to mount the lens to the camera.  don't expect too much, unless its a high end lens, it will not be as good as a cheap EF lens, and the TC will bring it down a big notch.
As to infinity focus using a TC, I don't know if its a issue or not.

You can't use the same adapter that he has now. He has an adapter for mounting an FD lens on a EF body. What he needs now is an adapter to mount an EF lens to a FD body. That is the exact opposite.

No one has ever made one, and no one ever will, because it would be impossible to change the aperture.

Lenses / New EdMika Polymer FD to EF conversion kit

Mini-Review for the new EdMika Polymer  FD to EF conversion kits.

Canon's Manual Focus FD lenses are legendary for sharpness, color, and contrast. Many people have discovered how well they work on various Mirror-less and 4/3 camera systems using simple ad-on adapters that go between the lens and the camera.   

Unfortunately there is no way to use a simple adapter with EOS camera without adding corrective optics which destroy the image quality.  EDMika recognized this a long time ago and has been developing individual conversion kits for EOS cameras. 

I was scanning through the various ebay listings and came across EdMika's new Polymer  mount conversion/converter/adapter kits.


He has recently added many more conversion kits for the FDn (New FD mount) series lenses and they are no longer made of Brass. The text of his ebay listing describes his reasoning for the change in material, and I think it is a good move. The Brass kits were extremely well made but they were heavy. I bet that in some cases the new brass mounts were heavier than the lens they were going on. The brass color also didn't really match the chrome plating of the camera mount and could also cause light reflections near the sensor.

These new Polymer mounts are also extremely well made, weigh almost nothing, and are completely black in color.  I really appreciate the weight savings when I use the lens with my SL1.  I am sure users with larger cameras will feel the same way.

I ordered the kit for the FDn 50mm 1.4  and it arrived in just 3 days.  The package includes a new mount, "Ed Bushing" (to engage the aperture), and a EdMika EOS lens cap.

The kit does not come with any instructions so you have to watch all the videos on the ebay listing page to get a good idea of how the various FDn lenses are taken apart and them assembled with the new mount. The kit is very easy to install and fits really well.

Here is the video that applies to to FDn 50mm 1.4 because it uses the  "Ed Bushing" that replaces part of the original aperture linkage. 


In my photos I show the partially assembled lens with the old silver colored ring beside the lens and the new  "Ed Bushing" installed in position. The "Ed Bushing" is also black in color and made of the same Polymer material.

The new Polymer rear lens cap is interesting, and lower in profile, but I think I prefer the standard Canon cap.


So here's my question and point of the post... I've heard that old FD lenses can still provide remarkable results and can be had for a song and used with an adapter. 

This is only true if you use a "Glass-less" adapter. In order to go glass-less you need to physically change the FD mount in order to move the lens closer to EOS camera body.  With other DSLR brands and all "mirror-less" cameras, this is not a problem and you don't need optics in the adapter.

Here is a good read explaining why it is difficult to use Canon FD lenses on EOS bodies:  (scroll down to "Canon EOS Lens Adapters") http://www.bobatkins.com/photography/eosfaq/manual_focus_EOS.html

Here is a direct comparison of an FD lens (with optical adapter) and an EF lens.  http://photography-on-the.net/forum/showthread.php?t=1028174

NOTE: there is a shiny silver "A" on the side of the lens in the picture, meaning this is their "Art" line of lenses - the same breed as the 35/1.4 that has blown away many many people.

Yea, there's a silver A on the side, but this lens doesn't really fit into Sigma's own definition of what an 'Art' lens is going to be. At least not at the time they announced this:


Art – These lenses are developed with an emphasis on artistic touch and are designed to meet the expectations of users who value a creative, dramatic outcome. Along with landscapes, portraits, still-life, close-up and casual snaps, these lenses are perfect for the kind of photography that unleashes the inner artist. Ideal for studio photography, they offer just as much of an expressive scope when capturing architecture, starry skies, underwater shots and many other scenes. This category will be comprised of many focal lengths and designs, such as large-aperture prime lenses, wide-angle lenses, ultra wide-angle lenses, and macro and fisheye lenses.

"This category will be comprised of many focal lengths and designs", might also include Super Sharp Constant Aperture 4.375 Zoom lenses with little or no distortion.

I was hoping Canon might come up with an improved 24-105 II, but this Sigma just might fill the bill.

I have noticed the same thing with my 24-105, but it also did it on my 5D Mk II before I got the Mk III.  You can actually see it in the exposure meter.

The IR wireless remotes like the RC-6 will AF and then take a photo, but it is done all at once. There is no "half-press" .

Wired remotes, (or radio wireless remotes that plug into the remote shutter socket), will do a half-press just like the shutter button.

Here is an informal Poll on the subject of EF 70-200mm 2.8 tripod rings:  http://photography-on-the.net/forum/showthread.php?p=7727815#post7727815

About 1/3 leave the ring off the lens.

You take a big IQ hit with the doubler.  I rarely use it (2XIII) anymore except on my 70-200 2.8L IS II.  I find I can crop without it and get better IQ.  I believe the added "feature" is not worth all of the hype.  Might prove useful with the video folks where the loss if IQ is also lost in the downscale to HD.  For stills, cropping is still better than using the 2XIII.

That was also my experience with the 70-200mm 2.8IS II. Cropping a 200mm image to match the 2x III 400mm image showed almost no difference. For me it made no sense in having $500 worth of glass sitting in my bag when I could just crop the image instead.

On the other hand the 1.4x II or 1.4x III both show a noticeable improvement over just cropping.

Anyone know where I can get one for the 300 2.8 canon?

I don't think you will find a 3rd party option.  How did you get if off the lens? I assumed they were not removable.

Here is the Parts List: http://www.micro-tools.net/pdf/Canon/EF%20300%202.8%20L%20USM.pdf

There is "no stock" on the entire ring, but it looks like parts are available.

Brand Loyalty ..... In the late 1966 I was 10 years old and started taking photos with my Dad's Kodak Bownie.   

He eventually bought me a used Canon Canonet QL19 (35mm film rangefinder)  in 1971 and I have been shooting with only Canon ever since.

My issue is this,

my original 7d and 7d accessory battery which I got from blacks a used to be large Canadian photo place anyhow those batteries when I checked them with the canon counterfeit document on there support site they were or would seem to be counterfeit.

the two which I bought from kijiji guy for 60bucks which I figured to be counterfeits according to there document are real....go figure.

but there is no way in hell you can yell me that 2 or 3 cells with protection etc..should cost mo more than what 20-25 bucks....sell them for 50. Buy no rob your customers....they are like 120 each here.....robbery..

Can you post photos?  The Canon  "counterfeit document" is very poorly written and does little to show the actual differences between real and fake LP-E6 batteries.

Take a look at this thread:


All of these are authentic Canon LP-E6 batterries. Do yours look like any of these?

More at f/1.4

I think this FDn 50mm 1.4 is one of the sharpest lenses ever produced and it even wide open at f/1.4 it produces excellent images...........

All wide open at f/1.4

I just finished converting my old FD 50mm 1.4 to an EF mount using the new EdMika Canon FDn-EOS adapter kit.  http://www.ebay.ca/itm/170911278282?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649#ht_2239wt_1344

The conversion process is quite easy to do for the average person but you really should watch the how-to video first.   
EdMika FDn-EOS kit instructions Small | Large
  The video is 12:21 and that is about how long it took me to do the entire conversion.

The kit consists of a really nice precision machined brass mount (fitted with a black sleeve to prevent light scattering) and a small machined peice of brass that is used to engage the aperture control after the old mount is removed.  The mount comes equipped with a "Dandelion" fully programable Auto-Focus confirmation chip. Also included is a EF lens cap.

Here are some photos of the lens after conversion to the EF mount. There is a small indentation for a "lens Mount Index". (mounting alignment mark). I dabbed a bit of red paint on it so it is easier to spot.
