Adaptall

But doesn't that lose all automation? Not only full-aperture metering,
but even automatic stop-down? My M42 adapter certainly does, and it's
on a K-mount Pentax!

There is no automatic stop down on a Tamron lens with an
adaptall for EOS...It will meter at whatever you set your
lens apeture to manually. Those EOS adaptalls are very rare.
I used to have one and a friend has one for his 200-500 Sp
lens. Rarely do they show up on Ebay. Last one I saw
sold for $90.

Wow. I thought the point of the Adaptall (and TS, T4) was to give the
automation that the T mount lacked. As to EOS availability, that's
odd, as this place:
http://porterscamerastore.com/Merchant2/merchant.mv?Screen=CTGY&Category_Code=L1N
claims to stock adapters for such popular mounts as the Fujica AX and
Rollei!

But the Tamron catalog lists no adapter for EOS; just for FD. I was
surprised to learn that the lenses and adapters are still in
production.

But there seems to be an EOS "custom adapter" on eBay today:

The Adaptall lenses have no electronic components, and the EOS bodies have
no mechanical ones, so the lens and body can't talk to each other.

The Nikon Adaptall lenses will mount on autofocus Nikons and many will even
meter with the lenses, because the mechanical connections exist. Ditto
Pentax.

Ah, yes, Hadn't thought of that.

However, many EOS bodies can meter with a non-electronic lens attached -
I've used several M lenses and accessiries with Elans and the EOS 3. I'm
sure they could do the same with the adaptall lenses - I just do'tn know if
a double adaptor system would be worth the work.

It is very easy indeed; Adaptall II for Pentax M42 and Pentax M42 to
EOS. Just leave both adapters on the lens. Couldn't be easier, and
the M42 adapter opens up so many possibilities with so many brands of
screw mount M42 lenses available at very attractive prices.
