M42 to micro four thirds adapters and legacy lens focus problems

Hi there,
after reading a bunch about folks using legacy lenses, thought i'd give it a try cause the price was right...

i have a couple of takumars i picked up at garage sales.
a 50 1.4 super tak and a 55 2.0.
lenses are in great shape with clear glass but i just cannot seem to get sharp pictures out of them. i use the magnified focusing aid in the viewfinder with my Panasonic G3 and nail the focus but when i view them in lightroom they appear poorly focused and no where near (not even close to) as sharp as my native panasonic lenses.

anyone out there have similar experiences with the legacy glass?
should they be at least as sharp as native lenses?
i've read the 50, 1.4 is a superb legacy lens but not for me so far.
has anyone ever had an adapter issue causing such problems?

just thought i'd throw it out there and see how others have faired before i go and sell the taks!

I have no idea but my first thought is to bracket the focus to see if a little more or a little less makes a sharper image.

I can't say I've been happy with results using 'legacy' glass. I have a Canon 50mm f/1.8 FD lens that is terrible unless stopped down quite a bit, which kind of defeats the purpose -manual focus AND poor IQ :)

I have adapted modern EF lenses onto a GH2 and couldn't tell it apart from the Canon dSLR image when stopped down (see here, click on photos to view larger). I have a hard time focusing manually with long glass using the magnified view, and with a 2x crop factor everything is long, or already duplicated with mft native lenses.

In short, I don't know what all the legacy glass fuss is about :) I'm sure there are some gems out there, but to start buying 'old' lenses when perfectly good native glass with AF is available doesn't make sense - if you have specialty needs it can be useful...

Hi Brad and Red,
luckily for me i only have about $50 invested in four legacy lenses.

since i now have the 50 1.4 panny i've found none of the legacy lenses give me anything even close to what the panny leica provides. it's way, way better than the legacy lenses and the 14-42 kit lens i was using!

i got caught up in the legacy lens craze reading the internet forums and thought i'd try it out for fun. has been disapointing so far. i really like having autofocus also. the only one i like is my canon fd macro...pretty nice lens.

fortunately, i can sell my legacy lenses and more than make up for what i spent.
i'm starting to think that's what i might do.
i just thought i might have an adapter than was causing me problems and someone might have had similar issues.

Brad,looks like your only a few away from 3000 photos on line!
you're a photo creating machine!
i'll never catch up to you (unless you slow down to a snail crawl).
advanced congrats on your very,very soon milestone!

Thanks for the encouragement :) I was actually at 3000, then disabled a few files - so here I come for the 2nd time!
