Shot with static Optosigma adapter. My Nikon D screen broke, and my Letus wasn't working (not Quyen's fault, it was mine, I didn't test my modifications enough).

All I can say is that I love the sun. I was able to shoot at 1.8, 1/8000 shutter even with this baby on. That much light = zero grain.

Ben,

The images look good, but I think your focal length is off - the focused images are a bit soft
BTW, what is the Optosigma adpater you speak of?

The focal length is indeed off, I changed it mid-shoot since it had been too close and I didn't have enough time to fine-tune it. The adapter I speak of is one suggested very early on by Richard Mellor, found here:

I had originally intended to build only this adapter but my Nikon D Screen arrived first in the mail, and, impatient as I am, I found ways to use that instead of the Optosigma glass and liked the results too much to try other options. Of course, once my Nikon D got scratches...

My adapter is built on the optisgma-glass and it works really good! I have some sample pictures at www.kokokaka.com/35mm. The adapter costs me about $250. It was not that hard to build it!

I get this: "You need Flash 8 to visit this site, download it for free. Best regards Kokokaka.com "

Yet I have Flash 8.

Also your giant and lengthy Flash intro is cute but my GAWD please put a "Skip" on there.

You may want to put a list or back/forward arrows on your list of More News. I had to scroll through the whole collection to get back to the 35mm link!

Ok, fixed the flashcheck now I think. No one likes my my site, I know. But you can skip the intro if you click on "read the koko kaka news" in the footer.

I use Flash 8 becasue it's really good on videocompression and you don't need any codecs, only flash 8.

People asks me if I will sell the adapter but I don't have the time to build it and sell it. It costs about $200 to build so if I want to sell it it would be quite expensive. When I have some time I will create a "build your own adapter tutorial" with links where to buy all stuff and more but first I have to build my next version of the adapter, I'm going to use two condensorlenses, +10 diopter, a better nikon f-mount and a lens holder.

I still can't get the link to work. It is just a blank black page with the koko type on the bottom. Nothing happens.

Jimmy I like your site! It's just that the intro is so long and you can't interrupt it once it starts, hehe

Just want to mention that ebay is a great place to get achromats.

Don't murder me, but I picked up the $200 Century Optics 7+ achromat on ebay yesterday for 73 bucks. Doesn't get much better than that, does it?

someone can post some photos of the condenser lens and of the proper GG.

in some threads I have read that someone use Aspheric Lens.
which is the difference?

I have chosen to use a GG of the Mamyia RZ.
what do you think of it?


thanks Manu
