I will gladly trade you some Pentax lenses with an adapter that you can use on your Canon for your FD lenses, I have a variety of lenses that are suitable for use on the Canon EOS systems without the need for a corrective lens.

Architect1776 Loc: In my mind

You stayed with an incredible and all encompassing system with Canon and one you can grow with and now ALL your EF lenses will work 100% perfectly no matter how old they are and they will also all work perfectly with the M5 and even better than they now do with the R system. So as I said get one of the Canon mirrorless for you FD lenses and your EF lenses will work perfectly fine as well. The R being Full Frame will better utilize the FD lenses as they were originally intended but I use them on my 7D which is crop sensor as well.
Number of digits does not determine if a camera is Full Frame or Crop with Canon. 7D and M5 are crop sensors.

I do not think you’re going to

I do not think you’re going to be happy with a cheap FD to EOS adapter (with an internal lens) for your 60D, but you can always try one - just make sure it’s returnable.

Do you still have the camera that you used to use the FD lenses on? If so I would keep using it even if only once in a while. Otherwise unless you want to get a mirrorless it's best to sell those FD lenses.

RE Adaptors allowing use of canon FD lens on APSC bodies
I used Canon FD mount film cameras back in the mid 60's. I was out of photography for many years and when I picked it up again, I opted for Sony Alpha mount. Having kept the old FD lenses I thought about using them so I bought a cheap adaptor that allowed me to use the FD lenses on my Sony. Once mounted on the Sony, My Vivitar 28 f 2.3, Vivitar Series 1 135 f2.5 and my Vivitar 400 f5.6 all took beautifully crisp photos but with 1960's levels of chromatic aberration. The Canon 50 mm f1.4 however yielded terrible results through the adaptor. But , due to their inconvenience of use (no AF, no auto exposure) on a body with no focussing aid screen and no way to view (Focus) through the viewfinder with the lens wide open for brightness, I decided that technology had made these lenses a mismatch to the new cameras. The were no buyers on eBay I ended up donating the lenses along with two Canon FD mount bodies, automatic bellows and all the canon specific accessories that I had accumulated to our high school photo club which still used film.

I shoot a Fuji X-T2 and there are focusing aids, another advancement is that the image you see in your viewfinder represents the exposure settings, ie, if you have a fast lens set at too slow of a shutter speed the image in the view finder will be blown out. As far as focusing aids they use highlighted fringing to show what is in focus as well as the ability to zoom in real tight while focusing in the viewfinder.

Actually the 7D is a crop sensor

First, there's no such thing as a Canon FD 28mm f/1.2

There are 28mm f/2 and 28mm f/2.8... And there are 50mm f/1.2 and 85mm f/1.2. But there has never been a 28mm f/1.2.

There were also several 135mm FD lenses.

None of them are easily adapted and used on modern Canon EOS/EF DSLRs (or EOS/EF film cameras for that matter).

The problem is that the FD/FL system used a 42mm lens flange to film distance. That's the distance the lenses are designed to focus. The modern EOS/EF mount uses a 44mm flange to film distance. So there is no room to install an adapter. There ARE FD to EF adapters with "corrective" optics to change the focal point of the lens... however the affordable ones are pretty poor quality. Canon themselves made a high quality adapter, but it was extremely expensive and few were sold. Today it's very rare and few that I've seen sell have brought over $1000. The last was some years ago, so I have no idea what they bring now.

There is a guy named Ed Mika who makes FD to EF replacement bayonet mounts for SOME Canon FD lenses. If you Google him you will find info, I'm sure. This requires mofifying the lens... removing the original mount and installing the new one. And it's not possible to do with all the old lenses.... so you have to check with Ed to see if there's one made for your specific lens. Last I looked, those Ed Mika's FD to EF mount replacement bayonet mounts cost about $100 per lens.

In any case, the lenses will be manual focus AND manual aperture only on your modern EOS camera. As you stop the lens down, you viewfinder will actually dim down too. At around f/8 or f/11 it can be hard to see to focus unless you have really good light. Larger apertures will be problematic in lower light conditions. Live View might help, with Exposure Simulation enabled to brighten up the image. Some adapters have a "chip" that allows focus confirmation to work, too... though AFAIK, none of Ed Mika's do.

A 28mm is a 28mm, regardless of the format it's used on film, full frame or APS-C.

28mm "behaves" differently on different formats. On a film/full frame camera it's a moderately wide angle lens. On an APS-C camera like yours, it will act more like a very slightly wide "normal" lens. If you have a zoom with 28mm as part of it's range, you can set it to that and it will be the same as using that 28mm lens (except the prime lens might have a larger maximum aperture and be better in low light conditions).

The 135mm is a moderate telephoto on film/full... or somewhat longer moderate telephoto on an APS-C camera. Once again, if you have a zoom with 135mm in it's range, setting it to that will give the same results as the 135mm lens.

That's correct. The 7D-series are APS-C format (1.6X "lens factor").

Also the 1D-series cameras are APS-H format (1.3X lens factor).

1Ds-series and 1Dx-series... as well as the 5D and 6D series... are full frame (1.0X lens factor).

I have some experience in this with the Ed Mika adapters using a T3i and an 80D. The link below gives you some idea of what is involved. I'm happy with the results that I have achieved on four or five lenses, but I would not do it again, I'd buy a mirrorless body and an adapter. https://www.uglyhedgehog.com/t-246186-1.html

As mentioned earlier, I use FD lenses mounted to a Sony A7II via a Metabones adapter. It's nothing but a metal donut: no glass, no electronics. The aperture is manually set on the lens. The shutter and ISO are set on the camera. Focus remains manual, but can be 'peeked' to 100% via the Electronic View Finder (EVF). Image Stabilization is provided by the camera body. Here's one example of the results with the FD 135 f/2.

Nice, the FDn 135 f/2.0 is a nice lens. I've been very happy with my Ed Mika adapted one, but mirrorless cameras have come so far that I now feel that is the way to go, although I would likely stick with Canon.

Once the FD-R adapters are in place and the pro-level R body is available, I'm looking forward to consolidating to just an EOS mirrorless body for both EF and FD shooting.

That sounds like a good plan to me. The nice thing about the Ed Mika conversions is that in most cases the conversion can be reversed, so long as you have kept all the parts. I may do that one day.
