If any hesitation, i suggested Ricoh Imaging using kickstarter to test the market + to help financially....
Let's see what eventually happens.

I don't think that Ricoh would like to be associated with kickstarter true their small camera business Ricoh-Imaging. It is also about perception off the health of the bigger company Ricoh. Ricoh is a traded company and investers are more important then a few hundred people wanting this lens.

May be somebody from this forum who writes Japanese fluently might point out to Tanaka-san that the Pentax Q lenses are manufactured by Nidec Copal (see their website and the page 13 of this brochure) so that he can include this information in his action aiming at bringing the lens to market?

At minimum focussing distance, which is around 14 to 15cm, Tanaka says the coverage is around 25 x 36mm. Hence the actual maximum magnification is around 1/4.6 or 0.22x.
Well, that kind of kills the deal for me. Unless the DoF advantage is really major, I'm not seeing much point. If it was a true 1:1, then that would be whole other proposition - getting 12MP (or 20mp with a new body) on a an object that's 7.6mm wide with such a tiny setup, now that would be interesting. But in any case, it seems this is just a prototype lens and the leak's purpose is actually trying to push Ricoh to release the lens? I doubt that it will work...

Do you figure / realise the impact of "on-sensor real to reproduction ratio" with 1:1 value on lens optic formula and physical position of the subject with such a system ?
I guess not.

(...)
With a 1:1 reproduction ratio, the distance between the subject and its image on the sensor is equal to 4f where f is the focal length.

With f=20mm (hoping that, in spite of the internal focusing, the focal length does not diminish too much when close focusing), 4f = 80mm from which you subtract the flange to sensor distance (9.2mm) and the length of the lens (50mm according to Tanaka-san).

The working distance (distance between the subject and the front lens) would therefore be equal to approx. 2cm instead of the 8cm of this lens.

So it is more like a close focus lens and not a real macro lens.

Looks like this lens by definition is a real macro lens. If I read it correctly and understood it.

This... is my point.
1:1 ratio would imply no internal focussing, therefore no fast AF... and no such compactness + probably no lens-hood occurence/room.

To make it simple, get a 35mm Limited + Q/K converter if you really wanna get 1:1 ratio, otherwise there is no point in making another tele-photo "macro" for Q.

He almost certainly knows anyway.
Indeed, from the start of this story,
I've harbored a suspicion that Copal could actually be the source of his copy.

If Ricoh abandon the Q system,
I would hope that they would sell the rights for other players to use.
That would be the time for something like a Kickstarter project.

Yes that would be great if someone would be interested to purchase the Q system. The longer it takes the less important it is since with time people put use of their q stuff into retirement. I don't see it happening, but maybe a Chinese player would love to have the Q system, if cheap to purchase.

It would really take young, hungry, and nimble management
to help the system realize its inherent "21-st century Leica" potential.
Unfortunately, in many ways, Ricoh seem to have feet of clay.

You need a fast moving low cost creative team. That is not so with Ricoh-Imaging and never was with Pentax.

Q would need a model with the new sensor of 20mp. Run on basic Android. Some new lenses. Get a sim-card. It could even run on a bigger sensor, with old lenses using just the smaller part of it.

As a happy Q7 user ( only recently bought the 04 and 05 'toy' lenses) I would aplaud Ricoh if they did launch the 09 lens, even if it would only be a limited 'special edition' batch, say a 1000 units ( just making that number up; no idea if thats viable). as a kind of kiss and farewell for the Q. Remember that Ricoh did limited editions with the Q before.

Of course I hope Ricoh doesnot pull the plug on the Q and acknowledges that for a certain kind of photographer, the Q is quite simply a brilliant thing.
Let us hope not. A 1k run would make the lens unaffordable for many. For the benefit of Q users, recouping a profit over a long run of the macro lens would benefit more of us.
