Here is a tighter crop of the waterfall picture.

Tighter Crop of Waterfall

Bob,

I was also surprised at how good the waterfall picture looked.

I got the adapter from Amazon for $15.00

The only thing I do not like about it is the lens is not 'tight' on my camera as it will rotate ever so slightly in the adapter ring, perhaps less than 1/32 of an inch. When you are used to new lenses not rotating at all that is a bunch.

Thank you Dan

I forgot to mention I found the Exif data is incorrect in showing the focal length at 50MM when it is really 135MM, and I believe the aperture shown is also incorrect.

Recently a friend gave me 2 lenses he found at Goodwill

http://www.uglyhedgehog.com/t-235718-1.html

Many of you participated in the discussion as to how good these lenses were. I ended up getting an adapter ring for the Pentax Takumar lens to fit my Canon 60D.

I finally got a chance to go out yesterday to try this new (but old) lens. Even though this lens is old, completely manual focus, manual f/stops I got a few decent pictures.

One thing I found by accident, since I am used to holding down the shutter button half way to focus the lens, I found if I do that with this lens, and IF the shutter is not entirely closed down my camera will beep at me as I am focusing when the camera finds focus! Also if I watch the internal light meter I can get an idea when the aperture is set close to the correct spot. I found it is not perfect I will need to take more than one picture at varying f/stops to get it right.

This first one is not perfect on focus or aperture but it is not bad.

The 2nd shot is of a water fall, that I felt the focus was very close to spot on. The 3rd is a crop of the water fall.

I have ordered an adapter for the Pentax 135MM Takumar lens and should be here the end of this week.

Looking forward to trying out this lens :)

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?

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.

A lot more info on adapting vintage lenses for use on modern Canon cameras can be found here...

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!

Thank you everyone for your help so far :-D

Are you sure it's not a "Toyo Five Star?"

You can see now that I posted the correct pictures it is TOU/Five Star

This is the 4th picture for the Tou/Five Star showing the lens hood stating it is for Canon

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 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 135 pentax is a very decent lens - the other, not so much ! - Go to the Penax forums to read about the 135 .....

Thank you. I did not know it was a Pentax lens
