Maybe I misunderstood?,

But if not, I'm going to (planing to list) pass this camera on, it's m42 with a matched Yashica Auto (switched) DX 50mm 1.4...

It's brand new: found in an auctioned off storage unit, in its original box..

Not kidding, it's brand new, zero signs of use??

pm me if this is fills your bill.

If I misunderstood, sorry



Just for information sake, I have a m39 Jupiter 9 2/85mm.

it works perfectly with a m39 to m42 adapter to match my m42 to Minolta AF adapter?

It registers to infinity perfectly...on my APS sized A700

so I don't know about that?
Best regards
fo

There's nothing wrong with "Big-Is" adapters, but the red line on lens (aperture, focusing) isn't "right" place....of course that is only cosmetic.


yeah, saw that one, and it was a just about the same price as Is-big's.

So what do you mean by better? I went with Big's because his English was less strangled, and the whole Chinese Melamine thing...

and it looks to be made of lead?

just kidding, but what's the difference?
Thanks

The black one looks like it might be a little better machined (like the outer ridge and the hole seems to have tiny beveled sides), which, of course, doesn't mean the performance is better. To me a black one just would go better with a black DSLR.

Well well well,

I got it just now and it works (is Big's 19 usd chipped m42 to Sony A mount adapter)

It works, I still focus by eye, but now glance down to ogle a green dot.

So far so good, I'm a confirmed focuser...

So proud...

The gismo is a bit fiddly to get on, you have to jiggle a bit then pop it's in...

Once twisted to lock it's solid and a perfect (not too tight--not too loose) fit...

Nice

I'm happy

but it doesnt seems can be used on av mode..
it does fire the shutter, but cannot change the aperture (for metering, i know lens aperture must be changed manually).. am i suppose to be able to do that in the first place?

You should be able to change the aperture on the lens, but not on the camera. As the camera can't control the aperture of these lenses, it should just believe that you are always shooting “wide open”.

No, I guess not... I get right with A700 and with A100.....

""but i think i always get underexposed pictures with m42 lens on adapter, is that normal?""

I don't know about normal, but it does happen--you have to adjust the EV for some lenses.

My modern Sony 11-18mm normaly underexposes on a regular basis on a700 for example.

that's one reason for having an EV button right handy like.

Totally something you can adjust for...

Enjoy

Well?

Look on the bright side, you bought a camera that an actual photographer might buy, not only can you now buy specialized Sony lenses, but a wide variety of third party lenses as well, even beyond that a simple low price adapter to use vintage glass to boot...

Having the ability to adjust EV is just more icing on your new splendid feature filled cake..

You see, you now can munch on the buttons of your cake---and have it too...

Do not overlook the befits of exposing to the right (of the histogram) on even those lenses that expose by the book...

You're down town now, so enjoy the shopping opportunities...

After all, unlike those point and shoot guys you're no longer stuck at home plate...

do expose to the right, and reap the benefits of a truly versatile platform...

Google expose to the right, and rejoice for the choice.

Do Enjoy

Regards
fo

yeah i think ive been narrow minded, just looking at the cons while not considering the benefits..

i know about the "expose to the right thingy" but seems a lil troublesome for me..

Thanks

Hi all!

Just have been through this thread. It seems it has shifted a little away from the intention of collecting information of different M42 adapters. Maybe we can revive the idea a little...so damian_bradley or whoever has the needed rights can add some more details to the post on page #1.

This is what I would like to contribute:

I have just bought a Pentacon 135mm 2.8 M42 lens and a chipped M42 adapter. It seems it might be the same adapter as described by glad2badad in his thread. It reports always 50mm focal length and aperture 1.7. It fits well on my A200, just like all other lenses I own. The viewfinder shows the green focus confirmation dot, that I too think is not too reliable, but the "trick" of press and hold the shutter, twist the focus ring, and the camera only shoots when focus is confirmed does not seem to work here. My A200 does always actuate, even when the green bullet does not appear. Seems this adapter has no real focus confirmation. The aperture can not be set to the "real" value on my A200 so this EXIF value, besides the focal length too, is not correct.

I have bought the M42 adapter via the bay at a Hong Kong based shop called MuchMall Link. It arrived very quickly. The package shows the name Pixco Adaptor M42 Minolta AF, it is made of metal, the build quality is good.

This is the original text from the store (I really don't know what that "bee sound" is supposed to be ;-)
