A practical answer to your question: go to Amazon for a PK-EOS adapter. Tamron made some great glass back then, but 80-210 was not in top tier.

But, seriously, don't do it. You have too good a camera to use a "not in top tier" lens. Plus, you have to manually stop down the aperture. Can your lens even do that?

LOL.

We’re talking here about an investment of $10 or less (there are even cheaper adapters on eBay) which will let the OP play around with a lens he already has. IMO it doesn’t seem like a very big deal to me :)

It appears you may not have spent too much time on this site. While perhaps Swamp Gator could have been more "gentle" in his response, if you hang around here long enough to see the sarcasm, disdain, and sometimes outright nastiness that can unfortunately result from innocent questions you'll realize that his comment was actually very mild and not a cheap shot.

While I don't shoot Canon, I do utilize any number of older lenses on my DSLR's... I'm attachng an image of the Nikon Lens cabinet taken about 5 years ago that has quite a few older & newer Nikkor & 3rd party Nikon mount lenses. While many don't measure up to current models, they all have a "signature" look that newer lenses don't have. It's a cheap way to get different focal lengths that you may not be able to afford in current stock. That said, my cameras can utilize the older lenses (AF where applicable & metering even with the older manual focus models), not all cameras can. Maybe someone who shoots Canon will point out the limitations. Many of my older Nikkors were "Pro" lenses when they were released & still are capable performers to this day.... I shoot a lot of macro images & my main "goto" macro lens is an older manual focus 3rd party offering...The lenses in the back left side are 300mm Nikkors, just so you can get a size comparison... Your Tamron zoom wasn't the best quality ( Tamron's "SP" line (Superior Performance was ))

Hi NY joe, I use a lot of old lens with my Pentax. That's what drew me to Pentax when I got my first DSLR in January, 2010. I found that a lot of Canon shooters use Pentax Super Taks with adapters. (I don't know anything about your Tammy). Some are on this forum. I believe the no glass adapters work best. Hopefully others will jump in. These adapters are fairly inexpensive so not much to loose if you are not happy with results. Do a search on this forum on Canon with adapters. I say try it. Good luck. From an ex NYer.

amehta, I like the utility of a short zoom with IS. I have noted the Canon offerings in the form of the 24-70 and 24-105 IS versions. I read many good things about these lenses but note that dxomark ratings seem to rate them as high average lenses, with a comparable Sigma 24-105 OS(lS) performing somewhat better. Dxomark's rating of the 5D mkiii as surprisingly comparable to the Nikon d800 providing it uses high end lenses is prompting me to look very carefully at the lenses I choose. I eventually will also be looking for a high end prime..perhaps the Canon 50mm. I look forward to your take on this and thanks for your interest

Thanks, Royden. I'll do some research on that, although Imagemeister's suggestions of likely poor image quality is foreboding.

Screaming Scott, So many lenses in the box and a mind that thinks out of the box...I like that combination! I wasn't making too much money back in the '80s so my old Tamron was the best I could do. Thanks for your input.

NYjoe Loc: US/UK

mwsilvers,

Got it...thanks.

NYjoe Loc: US/UK

Yes melismus, I learned that the hard way back in the '80s...just satisfying my curiousity. Thanks for chiming in.

Here's a short bee-themed quiz.... which of the following images was made with:

1. an old "crappy" $60 (used) Tamron SP 90mm macro lens adapted for use on one of my Canon DSLRs
2. a $500 Canon EF 100/2.8
3. a $1500 Canon EF 180/3.5L

???

If that old Tamron is an "Adaptall" interchangeable mount lens, all you need is a $40 EOS-Tamron mount from China. (There are cheaper, but the $40 version has a "chip" installed, so that Focus Confirmation will still work on your camera.)

If it's got a permanently installed Pentax bayonet mount(i.e., isn't an Adaptall lens), get the PK-EOS adapter someone else mentioned. This would also work with a PK Adaptall on the lens, if you prefer. These are also available "chipped" (recommended).

Neither of these incorporate any optical elements, there's nothing to negatively effect the image quality of the lens. They simply adapt the bayonet mount.

The adapted lens will be fully manual... both focus and aperture control.

Alternatively, the Canon EF 70-200/4L IS costing $1300 (plus another $160 if you want the optional tripod mounting ring) and the Canon EF 70-200/2.8L IS Mark II costing about $2400 (t'pod ring included), are both really excellent lenses. There are cheaper non-stabilized versions of both of them, too.... though personally I think the IS is valuable and worth the extra cost on longer focal lengths like these.

Now I know I need glasses. I thought it read, "old tampon on new camera". Don't tell anyone.

If that's you in a recent picture in front of the Hulk, you handsome devil, you're a long ways from old but I'll give you the other part of your equation, hands down. Me thinks however, that you're a bit masochistic and just like to invite people to infer mental anguish upon you.

When all else fails, a Google or ebay search can make a young man look healthy, wealthy, and wise. For a mere $12.97 you can find your desired adapter at the url below. It's a small price to pay for a lifetime of dignity and will keep you fairly safe from the risk of people overly complimenting you about how wonderful your photos are. I don't know this for sure but I would suspect that you can probably even special order a new 254.04 mph Bugatti Veyron without tires and pick you up a set at Goodwill with a little tread left on 'em. They may not be a matched set but they can get you on the road. Happy shootin'! :thumbup: :roll:

The link to the adapter that even beeps to tell you when you have found critical focus, a somewhat necessary thing in this case: http://www.ebay.com/itm/AF-Confirm-Pentax-PK-Lens-To-Canon-EOS-EF-Mount-Adapter-/120568000119?pt=US_Filter_Rings_Holders&hash=item1c1269ae77
