Goyo (Click here) made five new C-mount primes lenses that do cover the whole 4/3 sensor! Those are 12-16-25-35-50mm f/2.0 primes! To bad they don’t have a native m43 mount because otherwise this would be an amazing news. You will need to buy the C-mount adapter ([shoplink 21797 ebay]You can get them here on eBay for $8-$20[/shoplink]) to use those lenses.
On their website you can find sketches of the optics (no real pictures). They look pretty big. But finally we have some new lenses we can play with 🙂
There are no info about availability and price. And I didn’t fin any Goyo Lens on [shoplink 21799 ebay]eBay (only…”Toyo”! Is it the same?)[/shoplink]. That’s the list of the new lenses you can find on Goyo’s website:

Well, it’s the old story. Kowa and other manufacturer has the same lens design. But Kowa announce it would sell the lens in April, But it seems delay for the earthquake in Japan.
Nothing new here, these lenses should be exactly the same as the ones manufactured by Kowa. For details, please read:

the barrel lenght is quite long for those lenses: 70-80mm, even for the 50mm lens…what kind of lens formulas do they use, retrofocus type?
Presumably they have to be retrofocus or other design permitting a long backspacing, because otherwise there would not be room for the camera mechanism behind the lens and the “chief ray angle” (angle at which light rays hit the edge of the format) would be excessively steep. If you’ve looked at existing C-mount adapters for Micro 4/3, you’ll have seen that they already sit deeply into the camera body. A lens design that protruded even farther back than the face of the mount flange (as seen on some cine lenses for smaller formats) would risk mechanical interference with the camera body.
Having said that… the 25, 35 and 50 lenses don’t seem too interesting for the Micro 4/3 user (unless they are extremely low-priced) as there already are plenty of alternatives in those focal length ranges. It’s the 12 and 16 that seem to have the most potential to be useful… there already are some good wide-aperture C-mount lenses in those focal length ranges, but usually they don’t cover the full M4/3 format.

Goyo rang a bell…sure enough, my om-m43 adapter is made by them, in Japan. Bought in Malaysia. Quality seems OK to me, but it is a pretty simple piece of gear!
Found a store with some Goyo glass. No 4/3 stuff found

Thanks for posting, I did not know about this
The most famous Goyo lens amongst 43 users is the well-known Noktor 50/F0.95 – whith m43 mount. 😛
I have lost the source from a forum post in Taiwan but I still remember that this “large format” (1.3″ sensor is really large, in the sense of CCTV equipment) lenses is really not cheap and might cost over 1000 USD plus! This is for special purpose such as macro shooting for electronic component with least distortion. I am not sure why GOYO need to make such a lens. It might be cause it has to take care for the high resolution sensor that needs to develop the optic for fully covering. But I am quite sure, it is not going to make a great sales to the consumer side.
I used to have a Schneider 50mm f/2.8 which can cover m4/3. No double the definition of the lens is really great and the color rendition is truly reflexing the actual color of the object. However, it is still lack of AF and you may say it is lack of character too.

about $430 for 1″ f1.4 lenses
ar ha…never refering a cctv lens with “similar” specification.
The aperture is large but it cannot reflect the whole differences
from the lenses image circle. The sensor area is 70% large which means the whole design might be totally different.
You may go to Schneider Optics link below to see the price of 1″ and 1.3″ C-mount lens
1.3″

1″
https://www.schneideroptics.com/Ecommerce/CatalogSubCategoryDisplay.aspx?CID=1378
1.3″ is about double of the 1″ format lens, depends on focal length.
Looks like a 10 year old designed the website. Back in 1995. And they haven’t updated the design since.
they also have more 1″ lenses that should cover 4/3.
Not really interesting. All of these focal lengths have existing alternatives that are better:
12 mm – Olympus 12/2.0 with AF(soon)
16 mm – Olympus 17/2.8. Slightly slower but with AF
25 mm – Panasonic 20/1.7 and soon 25/1.4 mm. Faster and with AF
35 mm – Nokton 35/1.4 – faster
50 mm – Olympus 50/2.0 with AF
then why bother commenting???
Why the fuck does every idiot in this world misuse the word ‘too’ and ‘to’? Are they brain dead or is it just from the awful school system that poops out retards?
It is because nonenglish people give a shit about to or too.
Only the inbreed angloretards. 🙂
Why do these stupid lens makes go to all this trouble yet dont provide any links on HOW to buy them??
