I got this lens for dirt cheap on ebay without seeing that it was an FD mount. Now i need to figure out what to do with it. as some of you may know, it is near impossible to convert FD to EF, Icould convert to a tilt shift, or something else

here it is:

fuuuu just made the same mistake on dvxuser. I think I'm gonna go ahead and get a lens adapter just to have fun with an old lens.

Using an adapter doesn't effect how it looks really, unless you have a really shitty adapter with a bunch of glass in it. Some of the old FD lenses trump the new EF versions so i day pick up the fotodiox adapter(40 bucks i think) and go for it.

yeah they all seem to shoot decently. the series 1 is plastic and it seems to have something rattling around in it, but it shoots fine. its a plastic body though. whats so great about the 19-35? i picked them all up along with a couple cameras for 65 bucks on craigslist, so i don't know a ton about the lenses. learn me plz.

I just have read alot of good things about vivitar series 1 lenses, they are the best lenses they made back in the day and stomp out any of their old zooms they made, if youre gonna have an old vivitar zoom, series 1's are the best.

Always check ebay.. this one should work fine. You have to be careful when buying FD to EOS convertors because the physical mount on FD lenses is larger so than the EOS mount so you need a special convertor to maintain infinity focus, like this one.

Infinite focus is pointless unless you're taking pictures of the nebulas.

how far can i expect to focus if i dont have the infinity focus? just to the last marking on the lens be for infinity? cause that seems kinda weak, i take a lot of far away shots

You don't understand, infinite focus is made for shooting things MILE away, like the nebulas. There is something call "____" focal length, i cant remember what its call right now and how it exactly works, but basically its a certain point in your focus range that the majority of your image will be in focus and there is a small equations to help you find it based on your focal length. For example, on a 50mm usually you can focus to like 10ft and everything will appear in focus.

Also, you can stop down to 8 or 11 and this will help you achieve a very deep focus, infinity focus isn't needed.

Sorry, i didn't mean for my estimate to be perfectly correct. I was trying to recall an experiment i did last fall with my 50mm and i thought it was around 10ft. Landis knows what im talking about, he told me so i hope he chimes in or repsonds to my pm. But there is a point with every lens that it will be near infinity.

alright thanks so much for the help, i never knew that. let me know when he responds to the pm. it'd be great to put my fd lenses to use. when i bought them i didn't have my t2i, i just shot film for a while (good for my technique and all anyway) and i assumed i'd be able to convert them. and im assuming were talking video, because of your background in it. i'll still have good image quality for my much larger stills right?

It's called hyperfocal distance.

sweet thanks, so thats how things like gopros that are all fixed focus work? they're just a really close hyperfocal distence?

No, those are different, very small sensors have a very deep DOF, thats why dslrs can acheive such a shallow DOF. The smaller the sensor, the deeper the focus. Im guessing gopros are set at a certain focus (infinity or near) and stopped down 8+ so its all in focus. My hvx even at f4 can have a very deep focus.

alright well thank you so very much, itl be great to get a bit more usage out of these lenses, films so expensive :( and 40 dollars or whatever for the adapter is much cheaper then lenses to fill out those ranges, even if i do lose infinity focus because of it.

Thats kinda what I thought too but my friend had and FD lens with just a normal mount and the focal point was super screwed up and the people at my local camera shop said to try and avoid FD mount lenses..

Some FD adapters make it impossible to focus closer than just infinity though, try to find one with good reviews and all.

i dont really want to buy an adapter because i paid 15 for the lens, and 40 for an adapter would make it a 55 dollar lens, but it's shitty
