There are Nikon to m43 adapters out there, and pretty much any of them ought to allow you to attach. At 8mm, the Sigma fisheye should fill the frame, so the effect would be similar to that of a (so-called) full-frame fisheye, i.e. a 16mm fish on a 35mm camera.

@~tc~ I know it's tempting to use LMGTFY, but in this case the question is complicated because not all Nikon mounts are alike and aperture setting may be a problem with this lens ... so just googling for a Nikon adapter will probably not give the exact answer the OP needs, or could easily "lead them up the garden path" to buying something that won't be any good

Even if that were not the case, not all adapters are of equal quality, and our new member was asking for our recommendations.

This is right. I don't know much about Nikon mounts, but I have the Siggy for Canon EF mount. To use this on m43, you'd have to set the desired aperture on an EOS camera, push the DOF preview, and then turn the camera off. Since the EF spec. is all electronic, this leaves the aperture at whatever setting you chose. For me on my Canon cameras, f5.6 has been fine, but it is noticeably softer by f11, likely due to diffraction.

Hope this helps, Sean

No, he asked

Normally, I use the Sigma on a Nikon D200 but was wondering
if there was an adapter to allow use on my Lumix GF1
I have been a mod on forums before, and if you don't set the expectations that people do some level of basic research before posting, it's not long before the "search noob" Nazis are out in force.

If he had said, "I see novoflex, rainbow Imaging, and some no name ones on eBay are available and the price varies wildly, does it make any sense to buy the more expensive one" it would be a different story, but, alas, that's not what he asked. He asked if one existed. Yes, several exist - next?

Sometimes it's worth making allowances that not everyone asks questions in the same way we might ourselves ... you've spelled out reasons for responding as you did, but the OP might have found it helpful to have them spelled out as a first response ...

You left out an important part (bolded):

if there was an adapter to allow use on my Lumix GF1 and if anyone had any recommendations?

Many thanks :smile:
Looking forward to your input.

The primary expectation in this forum is that members are nice to one another. "'Search noob' Nazis" will be shown the door.

Thanks everyone for taking time to respond and offer advice and welcome me to the forums.

I do realise that there are adapters by Panasonic, Olympus and 3rd parties which allow connection of non MFT lenses into the MFT cameras. It would be reassuring to find someone with that exact Sigma/Nikon Mount who had used it successfully on a M43 with an adapter.

My caution also stems from the fact that I brought my Lumix GF1 and Sigma Fisheye into a camera store twice and was told by two different assistants on two seperate occasions that the Sigma lens and Lumix GF1 were incompatible.

What I hope to do is pop into a different camera store with my gear and actually ask them if I could try to attach the two in-store with one of their adapters.

Will post back and let you know how I get on. Hopefully if it works, I can add the details to the adapter database / wiki too :smile:

Hmm, camera store assistants! If only there was a rule that working in a camera shop required knowledge and experience. Probably too much to hope for.

X2 - I have yet to see any adapters (for anything, let alone m43) in any camera store. No surprise the salesperson didn't know what you were talking about.

Quick update. I emailed a number of vendors and they have pointed me to suitable products. However, I've decided to invest in a Panasonic 8mm Fieheye instead of adapting my Sigma. Granted it's going to be more expensive but weight is an issue with the Sigma when I combine this in my backpack with a tripod, pano head, leveller, rotator etc. Hope to upload some images soon.

I should have known from the "360" in your name that you were into panoramics - that's one of my hobbies too (there's a few examples at the link in my sig.). I'd be interested to know how the 8mm Panasonic fares, especially if there's enough coverage on a 4/3 sensor for four around + zenith ?

Hi Sparkin
Nice panoramics there.
Hoping to pickup the lens next week so I'll have examples as soon as get the nodal point down etc :smile:
I reckon the best approach will be 4 around at a sligh 5 or 10 degree angle upwards and then a seperate nadir.

Hi Sparkin

I've put together a 360 degree image using the Panasonic Fisheye lens.
The 360 Company - St James' Church - Great Ormside
Will probably take another pass at this image but it gives you an idea.
The lens is so tiny and light, its very easy to stick this, a tripod, camera and pano head in a bag and hit the road.

By the way, the website linked above has just been relaunched and some of the other Panos are not fully ported across so you might encounter some bugs on the other photos. Feel free to leave a comment on our blog. I'm testing the commenting function at the mo.
