for a 500mm telephoto lens, don't you need the infinity focus ?

The longer the focal length the further away near infinity is, on a 28mm lens it might be 20 metres but on a 500mm it might be 100s of metres.

Question about using an adapter with glass. I just picked up a Sigma 600mm FD for Canon and purchased an FD-EOS adapter (the kind with the glass) and have tried some tests shots. Seems to me to be very "soft" or maybe not as sharp as I had hoped. Is this mainly due to the adapter that is causing this? I've attached a link to some moon shots I took a couple of weeks ago. All were using a tripod, live view to focus, and a 2 second timer to avoid shaking the camera.

It would be good to see some daylight examples to gauge the sharpness.

Thanks , everyone - picking up a lot of info .
Looks like a lot of people want this stuff on ebay .
Infinity I don't think I need - I want for flowers - like a blooming stinging nettle, bugs - like a wasp or mud dobber nest . Probably a tripod at 3 to 10 feet .

Hi all.

I have been lurking on this thread out of a mild intrest in mirror lenses.

I was talking with my dad tonight and he mentioned that he had a Canon 500mm mirror lens that is a fd mount. I am not sure if it is a f8 or f5.6 or it's condition. Needless to say my intrest was perked up with what I hav been reading here. He also offered up a whole boat load of fd gear but that is fo an other thread.

I have seen that some of you have successfully converted a fd mount to eos mount. I also have seen a number of links to eBay that might have the parts necessary to make this conversion. My head is spinning a bit and I can't make heads or tails of what is needed to do this as cheap and as reliable as possible.

Will the fd to eos converter I saw be best? Will I loose infinity focus? Would removing the old fd mount and installing some type of eos mount be best? What parts would I need.

I am new to my dslr. ( a newb... Newbe.. Not even sure how to spell this).

Sorry to OP fo jacking the thread. Thanks for starting it though.

Bill

You might get lucky with a glass-less FD to EF adapter due to the lens focussing past infinity as standard. To replace the mount you'll have to drill the new mount (the FD to EF mount might suffice) to match the screw pattern of the old FD mount.

Thanks. I was ably to find your recommended mount in post 96. I will have to get this mount before I pick up that lens. I can drill it out easy.

Thanks The ran and r morales for your suggestions. I will probably get that fd adaptor for other projects.

Thanks for all your help.

I read , make a word doc. My memory sucks

https://photography-on-the.net …7&highlight=mir​ror&page=2

I think the following are quite good for canon cameras.

New Canon 500mm f/8 FD
Sigma 600mm f8
Olympus Zuiko Reflex f/8
Tamron 500mm f/8 SP

The bottom of a coke bottle would be sharper than these. (mainly korean made and rebadged)

Opteka 500mm f/8 and 800mm f/8
Samyang 500mm f/8
Vivitar Series 1 500mm f/8
Phoenix
Cosina
https://photography-on-the.net …p?p=11534824#po​st11534824
Opteka, Samyang, Falcon, Rokinon are all just rubbish !!! not sharp and no contrast ... don't buy any of them !

Really? I must have missed that. I thought I had been following the thread very closely but apparently not. I will go back and re-read.

After a few weeks of being tied up with other things, I've finally gotten some time to go out and have a play.
My 4th generation Adaptall2 to EOS adaptor turned up a few weeks ago. First impressions are very good, it's a good bit of metal with no excess glue on the chip, or anywhere in fact.
I still have not programmed it, but for a first play I think these are alright. Please bear in mind, it's cold and very overcast in the UK at the moment.

Both taken with Tamron SP 500 mirror lens, supported with a monopod and no cropping. I think with better light the lens will be pretty good and sharp.

Those are great shots .
Where / who did you get the chip from ?
Is it used in these shots ?
please post more about installing and programing - hopefully on a 7D or XTI .
Probably the same as the 50D - I hope .
