I agree on the 135 f/2.5 - it would also be a good lens on micro four thirds with an adapter.

The zoom - meh. And Nikonian72 will tell you that 1:4 is not macro. I have this same exact lens headed to my Ebay box.

The only lenses I see at Goodwill any more are f/1.8 50mm, f/2.8-3.5 135mm, f/3.8-4.5 70-200 plus or minus a few mm, and an occasional 28-85 type plastic kit lens. Also the occasional f/2.8 28mm, but they're usually junk.

The Sigma Hood I used from a lens I own just to hold the lenses better.

I see now I totally screwed up posting pictures of the second lens - I actually posted the same lens twice - how embarrassing is that!!

The second lens is the Canon FD mount that was around for years. I still say adapting it to a modern Canon DSLR is a waste of time and money. No autofocus or aperture control. Nothing but frustration. The lens was marketed under several brand names and is cheap in physical construction. :thumbup:

Ok. But to me I wouldn't bother. Make sure it will focus to infinity if you go for it. Usually an adapter will increase the distance of the lens from the body and the focus will come up short of infinity. :thumbup:

The Pentax bayonet "K" or "P/K" 135/2.5 will adapt to Canon EOS/EF just fine, focus to infinity and is definitely worth adapting and trying out. I would recommend getting a good fitting lens hood for it... similar 135/2.5 from other manufacturers that I've used were wonderful lenses, but a bit prone to flare due to the large, vulnerable front element... a good fitting lens hood solved that.

There are unchipped ($25) and chipped ($40) Pentax P/K to EOS EF adapters widely available on eBay and elsewhere. I use the chipped because those allow Focus Confirmation to work, which can be very helpful trying to use old manual focus lenses on modern cameras designed for auto focus and without any support for manual focus.

With the adapted lens you can use the camera's metering system with a "stop down" method... And will need to set the aperture on the lens itself. Your viewfinder will dim down as you stop the lens down. You can use the camera in M (manual) mode, or in Av (aperture priority auto exposure). Other modes will not work.

The Tou Five Star zoom is Canon FD mount and that's not easily adapted for use on modern Canon EOS cameras. The lens will not focus to infinity, unless an adapter with optics is used. Those generally are utter crap and make for very poor image quality. At one time Canon made a high quality FD/FL to EF adapter... But it acts as a 1.26X teleconverter and is a rare collectible now... always was rather pricey, now if you can find one you should expect it to cost upwards of $1000.

That Tou Five Star zoom is not broken... All FD/FL mount lenses "lock" the aperture at f5.6 when removed from the camera... changing the setting or flipping the lever will have no effect. There's a small pin under the flange of the mount, that when pressed (i.e., when the lens is mounted on the camera) allows the aperture to operate normally.

But, as already stated, it's likely not worth adapting. It's nothing special... just a very common, cheap third party zoom. Sell or give it to someone who uses old Canon FD/FL cameras.

The Pentax bayonet "K" or "P/K"... (show quote)

Good info and advice. Especially about the infinity focus. The lens focus could be adjusted somewhat but with a zoom the focus has to be adjusted at the full wide angle setting and the full zoom setting. Very time consuming to get it dialed in and most repair shops would not want to fool with it. I know I wouldn't. It's not worth the trouble IMHO. :thumbup:

The Pentax bayonet "K" or "P/K"... (show quote)

Thank you so much for this valuable information! I was beginning to wonder if it was worth looking into buying an adapter ring to fit my 60D but now I want to for the Pentax lens. The Canon FD lens I will keep for a while anyway.

I found an adapter on eBay I am hoping will be the right one

Can you help me also find a lens hood?

Thank you!

I want to thank everyone who has participated in this thread. I am learning this is a great and very friendly forum for getting photographic advice :D

Thank you!

Takumar and Asahi appears on the lenses from what I can tell. That would indicate Pentax. They appear to be Pentax K Mount from the 70's and 80's. The shade is obviously from a Sigma lens but maybe you were just using it to hold the lenses. I'm not sure where you came up with Canon. Some other brands adopted the K mount. Ricoh for one. A waste of time to try to use them on the 60D. No AF or aperture control. Just my opinion.

The aperture control is in the lens.

The second lens has a mount that really looks like the old Canon mount for AE-1, A-1 and other film cameras before the FD bayonet mount and before the EOS series. That mount actually engaged the mounting flanges on the camera, with the threaded black ring shown on the lens to draw in the lens tightly, using a bayonet motion. The FD mount was a true bayonet mount. Both styles work with the same Canon cameras.

I just again went to eBay looking to buy an adapter for the Pentax lens and found several that have the chip which sounds like a great idea (if they all work) but what surprises me most is the variance of the price. I have seen them as low as $8.99 on up.

How do I know which one is reliable?

I have a genuine Pentax 135mm lens hood that I would sell you for $10 delivered. I would prefer payment by Paypal if you are interested. I can take a picture of it for you if you want. PM me if interested.

I was thinking the same thing. The knurled ring close to the mount looks like the chrome ring on my old Fd breech lock Canon lenses. There are adapters but they are only worth it on the best of the Canon Fd lenses. They add length and you loose a stop and all auto functions. But all the Fd lenses were manual anyway. I am thinking of getting one for my 50MM 1.4 Fd lens. I figure I will have a 2.8 125mm portrait lens.
