Personally I think even the relatively poorly reviewed Sigma 150-500 will match the resolution and resistance to chromatic aberration of the FD 500 with autofocus and the convenience of zoom. That said, I've never shot an FD 500 4.5 and only tried the Sigma at the store so take that with a big grain of salt. Where you won't find a reasonably priced modern equivalent though is in the 600 and 800 FD lenses.

According to the seller of the EOS converted FL 55 1.2 listed on ebay ( http://cgi.ebay.com …1e62beae86#ht_8​008wt_1141 (external link) ), there is an interference issue between the rear lens element and a full frame mirror which is strange to me as the lens I had a prototype conversion of did not interfere with the mirror on my 1D4. A great amount of testing still needs to be done apparently before I release a conversion kit.

True... but the mirror on a 1.3 crop body is the same size as that on a full frame body as far as I can tell with me comparing it's size and design in the past to an eos 650 and a 5D1.

My question would be is if an old FD 500mm f/4.5 is still better than say, a Sigma 150-500...

Don´t know - don´t have used the Sigma.
I have converted a FD 500mm f/4.5L to EF mount, some full resolution pictures made with this lens and a EOS 5D could be found on my lens conversion HowTo.

As of 1 hour ago I officially confirmed the 3rd FD lens that will focus to infinity using just an EdMika EF-FD 0.75mm adapter and a simple 20 second reversible lens modification.

I am so happy that this particular lens works fully on EOS/EF cameras since it is one I am using on my Sony NEX very often lately and I love the sharpness and lack of chromatic aberration.

I'm holding off announcing what lens this is yet because there is an extra copy on eBay I hope to snap up first. Give me a week or so lol.

The lens is the FD 85-300 f/4.5 a beautiful beast that has next to no CA and is as sharp wide open as the 400 4.5 prime. I have infinity focus between 250-300mm on an EF mount using the EdMika EF-FD 0.75mm adapter and with the removal of a single external screw.

I got one of ontarian fd/eos adaptors, it works well with telephoto fd lenses like the 500mm f/5.6 mirror. It nearly focuses to infinity but requires +20 micro adjustment. The AF confirm comes in very useful with slow lenses like the mirror lens when they are not as bright in the viewfinder.

Forgive my confusion, but how does microadjustment help?
I was under the impression that MA applies an offset to AF lenses, so I'm not sure how this would help with an MF lens?

Apologies if I'm missing something obvious :)

Ever since I saw this thread I started thinking about buying an FD 600mm f/4.5 lens. An excellent condition one just sold today for $900 which seems like a bargain when you consider that the EF 600mm f/4 lens is selling for as much as $10K.

I got feedback from another buyer of the EdMika EF-FD 0.75mm adapter that they got their 500 mirror to infinity by removing a focus stop screw under the rubber focus ring.

so the new ones don't smack the mirror on the 5D2 (one of your links still mentions that it does if you focus past a certain distance without using liveview, so is this some new version that avoids that?)
