I use both the jtat and Alex's m42 adapters, i have both versions with and without flange. The flanged version will not allow my Auto Tak 50/1.4 to mount correctly. The version without the flange is great for this lens.

I haven't got much experience with MF lenses yet, but it appears the pins don't fully retract into the body of the lens, is this a correct observation?

I simply swith my auto lenses to manual and away i go.

Sounds like you might of made the mistake of using an M42-PK adapter instead of a proper M42-SA adapter?
The former is a couple of mm shallower than the latter and therefore it can allow the rear elements of M42 lenses to hit the dust protector. I only know of a couple of M42 lenses that have been reported to hit the dust protector when using a proper M42-SA adapter (The Yashica 28mm f2.8 and the Tomioka 50mm f1.4) but that was reported by only one person...Someone else reported that they did'nt hit the dust protector, so its seems there is some variabilty in fit between supposedly near identical lenses.
If you can show me a picture of your adapter I should be able to confirm what type you have.

Just finished a nice tinkering project. Converted a Sigma SD9 to Exakta mount. Removed the SA bayonet mount and the protecting filter and made a new mount, using a self-made adapter ring that screws to the body which holds the Exakta mount. Decided to have the scale at approx. quarter to twelve, because otherwise my auto-diaphragm lenses from Zeiss, Steinheil, Schacht, etc... would not mount because of that prism "nose". For better focussing, I slaughtered an already broken Porst camera and installed that rangefinder screen at the SD9.
Overall a nice work and everything is working very smooth. Now I can mount my Exakta lenses and it will be fun to choose one for a walk with the SD9 from time to time.





Now that really bad weather has to improve to try it outside.

Nicely Done Klaus Very Happy
That is a great way to make use of the Foveon.

Looking forward to some samples from that 2/85 Sonnar.
It's one of my favorite lenses. Mine is the RF version for Contax.
I've never found a Reflex version for sale Sad

No wonder, only a few were made for Exakta.

[DSG wroteThere are a lot of dodgy M42-SA adapters in circulation on ebay.
Avoid any M42-SA adapter that do not have an AA pin compresser flange built in...Here is an example of one that should be avoided:

unfortunately i had not read this thread and i bought this one. it seems to work fine, though i just received a sigma 21-35mm m42 whose AA pin is not properly pushed in with this adapter--but this is the first problem i have encountered. can i be doing some kind of damage using this adapter?

Nice work Klaus,

Is the SD9 the same as the 10's and 14's with the IR filter, i assume that this modified 9 will be used for IR shots only?

Hi, in contrary to the SD10 and SD14, the SD9 has the IR filter combined with the sensor. So it works fine without the dust protector, but I will have to clean the sensor more often.

Hello Sigmafellas!
I have recently decided to give M42 lenses a try and also bought one lens. Next question is, which adapter to choose? There are lots of adapters on Ebay and cheapest are under 10e but are they any good?


PostPosted: Sun Nov 15, 2009 10:03 pm    Post subject: Reply with quote
hi and welcome

dont try the cheapest. look in this thread for a post by member DSG who has a link to what is probably the best adapter for sigma>m42. i myself use the second adapter listed in that particular post, which is listed as a dont use, and i have not had any problem. however were i just starting i would take DSGs advice as he seems very knowledgeable.

cant wait to see some pictures.

SD14 + Pancolar 50/1.8 via the cheapest adapter

It focused past infinity - not very handy and I'm afraid it will scratch the filter, but it is not.

Some samples




Corner darkens because of using unsuitable DIY hood from rubber hose.




Monochrome option in SPP




Monochrome with higher contrast

So long time, no see!
I'm looking for a f/1.2 lens for adapting, which one do you prefer. I would like it to have pretty good bokeh and somewhat sharp (of course at f/1.2 the sharpness isn't the most important but still.. Very Happy )
I have Rokkor 58mm f/1.2 or Pentax 50mm f/1.2 in my mind, they both supposed to be pretty good. Do you have any other lens suggestions or which one would you like to take?

Atleast with Pentax I think the conversion would not take more than 10 minutes (most of the time looking for tools Very Happy ) but Rokkor supposed not to be so hard to convert.

But please, if you have something to say please feel free! Very Happy

If I were you, I'd consider the Revuenon 1,2 with PK mount. Easy to convert, but needs a 1,5mm shim.

I have an old CSM42 adapter, an high quality adapter once made in Japan that comes with a separated flange ring. I've actually glued the ring that came with it, but later took it off (with diluent), so that I can use the M/A control that exists in all my M42 lenses to activate/deactivate the diaphragm. All M42 lenses I have work just fine with this adapter both in a SD14 and a SA-9 film body.

Concerning incompatible lenses: I have the first version of the Super Takumar 50mm f/1.4, the one with 8 elements, that slightly touches the dust protector when set just a bit above infinity (my lens infinity was calibrated so that it focus well in some broken soviet cameras... infinity in a Spotmatic or well adapted camera is between the oo and 10m mark), but this is not really a problem since I've used it a lot and never scratched either the dust protector or the lens. I can actually feel the lens touching the protector at the end of the focus scale, so probably any lens having the same problem would not brake anything unless you focused it carelessly the first time you tried it.

BTW, the dust protector assembly is plastic, and flexible: the lens touches it and can keep moving past that point. Probably not much, but in my case enough that the lens stops at the infinity mark well before doing any damage.

Does the SD-14's focus confirmation work with "normal" SA/M42 adapter, or it does need a dandelion?

Bought a Konica Hexanon AR 40mm f1.8 lens today. Anybody know the best way to adapt this to a Sigma SD14?

I already have a nice SA to M42 adapter. But I can't seem to locate an AR to M42 adapter.

No external adapter possible, register distance for Konica Hexanon AR is 40.5mm whilst Sigma's are 44mm, so the lens should be "cut" by 3.5mm to focus properly. You can only use adapters when register distance of the lens is shorter than register distance of the camera, the difference in the thickness of the adapter. In this case negative, then not possible without cutting a slice from the lens...

Hexanon lenses can be mounted on 4/3 and micro 4/3 cameras, that have a shorter register distance.

Jes I appreciate the reply. Thank you!!

Furthermore, I agree with your assertion. The Konica register distance is, indeed, very short . . . . unusually short. The Konica lens, if mounted onto a Sigma SD14, will not allow focus to infinity.

Still, the Konica is a pretty good lens. I'd like to mount it anyway just to play with it. Looks as if this might take a little machine shop work.

Thanks again and best.

Yes, it does focus confirmation. The only quirk is that you must mount a sigma lens each time the battery is changed and take a shot. After that the camera will confirm focus with any lens until you need to change the battery again.

Any cheap sigma lens will do.

I got a nice Carl Zeiss Planar 50mm 1.7 converted to Sigma mount. It works very well and the Foveon sensor helps in getting the most of the planar colours.

These days I've been doing the last trimmings to the trees in the garden, I needed to use a pole with the trimming scissors at the end. It was not used since past year, so it was a little rusty and full of spiderwebs and some dead spider. Taken wide open. Colours are realistic. I love the smooth bokeh.





Some issues with the Planar: Wide open needs to compensate the exposition by -0.3. Also the focus confirmation becomes critical, a short pulse on the green led when passing over the focus.

Keep trying this nice lens.

Regards.
Jes.

Nice pictures Jes. I'm waiting for the price of the SD15 to drop before following your route. Smile

To me the SD15 gives only marginal benefits compared to the SD14, at a much higher price. I look forward to see wich price tag do the Sigma fellows set the DP1, but until then and by now I'll stick to the SD14 and the DP1s, and probably will be selling the SD9 (that I barely use).

These days I also look (with much excitemenent) to the Sony NEX line... Wink

Next days I'll be trying the Berogon on the SD14. Keep posting.

Regards,

Jes.

Jes, the SD15 has improved wb, high iso and color handling compared to the SD14: with my DP2 (which has the same processor as the SD14), I often get green corners or weird color casts, and ISO 400 is barely usable for colour shots. The SD15 is also much faster, but you are right as for its price: until the SD1 comes out and the SD15 price drops considerably, it's just too expensive. German prices have come down already, so it's just a matter of months.

I don't: I much prefer having an optical vf, but more importantly all the Nex shots I've seen so far, and there are lots even here, look dull and flat. I absolutely dislike its IQ.

Ludoo, I wentto the NEX-5 way. Wink
Please, look at my threads on it: I see no dull colours at all, and even 12800 ISO is useable by turning the pics onto B&W:

http://forum.mflenses.com/first-impressions-with-my-nex-5-t37592.html

And some shots with the Jupiter-9 in this thread:


http://forum.mflenses.com/1965-alu-jupiter-9-strange-finish-question-t37720.html

I agree that shooting without a viewfinder is more difficult, but the outstanding results, having an APS-C sensor and the price of the camera (IMHO) justifiy the investment. Since I own the NEX, I've not used any other cam Smile

Regards.
Jes.

Doesn't seem like a big issue though, being only3/10ths of a stop difference.
I remember the very nice green led that confirmed focus - really handy.
