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.

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


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.

Jes, I saw your shots in the past weeks, and while they look really good I don't find the "Foveon look" in them: that special combination of sharpness and micro contrast/color variations which I love. Plus, the Nex has no viewfinder and for my type of shooting (mostly people, not posed) it would be useless.

Sell my your SD14 then. Smile

I was thinking so. With the DP1s I'm Foveon covered....
I'm open to offers, I have several SIGMA lenses for it. Wink

Let me take some shots of the cam and the gear, I'll be posting them onto the Marketplace, but you have the first option...

Regards.
Jes.

Hope someone out there might have a thought on this:

I have the Sigma SD14 running with (among others) Tamron Adaptall 2 MF glass. At present time I am using two adapters:

Adaptall 2 to M42

M42 to PK

This works.



Perhaps, but it does'nt work properly! You should get a proper M42-SA adapter instead for perfect fit and accurate register.

No but an Adaptall to PK adapter exists and thats fits the SA mount too, albiet, with a little play in the fit.

A better alternative does exist, simply get yourself a cheap Polish made M42-SA adapter and you will have a perfect fit with your existing adaptall-M42 adapter. Wink

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


I use the Canon FL 55mm f1.2...Converted it to SA mount. Wink

I appreciate your reply albeit I'm only just seeing it for the first time now, many months later.

And, yes, I did discover in the interim you are correct and I can confirm your wisdom regarding m42 to PK vs. m42 to SA for the SD14. The latter is, indeed, better and one encounters less "slop" using the correct SA adapter. The PK does work, though, and will allow photos to be taken in a pinch. However, I now use only the m42 to SA adapter as per your thinking. Incidentally, I bought the brass adapter from China. It is silver in color. I have since seen negative comments written about this adapter, though I've not myself had any trouble with it whatsoever. I like it.

This trick, provided it works consistently, is a very attractive alternative to use of a dandelion. Has anyone else had good fortune with this "take one shot with any Sigma AF lens then change to MF lens and go from there" approach to focus confirmation?

I think if this works consistently it's a pretty big deal, and a really wonderful help.

I have never used this approach. I have a black M42 adapter (I think it's the Polish made one). I just stick it on and I get focusing confirmation. I always use M.

They pretty much the same when it comes to mounting glass right? sure why not. Wink

Just a question - does exist adapter for Praktica Bayonet lenses and Nikon-S lenses for use with sigma SD camera?

I found M42 only...

I have sought over a number of years to locate adapters for Sigma SA, other than for m42. So far:

NO LUCK!

The quest goes on, but I'm afraid I might actually be able to locate the Golden Fleece itself before I ever find desperately-wanted Sigma SA adapters!

Of course it is possible, at great cost, to replace entirely your camera body's Sigma SA mount with another mount. That is not an alternative that beckons to me, however.
