A coworker came across some lens and a flash at a yard sale and was generous enough to bring them in for me.

He brought me a

1. Acheiver 260T flash
2. Spectrum 7 28mm f2.8 wide angle
3. A CPC Auto 28mm Macro lens

From the research i have done i believe both these lens are ED mount?

As in Minolta? I believe i have found an adapter for like 35$? Does that sound right?

From what i read you will lose infinity focus and have to use a stop down technique but other then that they will work fine?

Not sure if this is correct as it was only really possible to find info for the spectrum 7.

Also since the flash is a hot shoe mount it will slip right onto my 550 right?

Here are some pictures- all help is appreciated!!

The sparking voltage (not sure if thats the correct phrase in english) of the flash is 260 V - way too much for your 550D. So please don't try except you like the smell of smoking plastic. No - no jokes about that, don't put the flash on your cam!
No clue regarding the lenses - do they have an ring for adjusting the aperture manually?

Cheers

ED mount?

This one a bit better though.

I'm guessing that these are K-mount lenses with aperture levers. There are some adapters for K mount to EOS, but Bob Atkins claims the aperture lever on the lens will need to be cut off.

I'm not sure why they got you two 28mm lenses - return at least one if you can.

Thanks that is what I wanted to know.

The lens that you posted are exactly what I have.

So they are k mount eh.

Is there a diy available for getting this to work? Id like to keep at least one of them.

The guy who bought them for me doesn't have a clue about photography so that's why he got two 28mm.

At the very least you will need an adapter and then it might still not work without altering the lenses, as Bob Atkins said. The adapters have relatively complex machined designs, even though at their most basic they are a simple brass ring they must accommodate both the EF mount and the mount of the lens.

Btw i found a adapter on Amazon that claims infinity focus will work and that has solid feedback.

Also found a blog post about it-

And from what i've read, it is usually easier to just pickup ES-F lens, but since i got these two lens for free, im going to just try and use them until i have money to get a good zoom lens(which is all i want really).
