Coke Bottle Bottom. Sounds quite rude this way, doesn't it?(Anybody seen a bottom-of-a-Coke-bottle for Micro Four Thirds yet?)
I got my Tevidon when prices were still less than $100. When it arrives, and the adapter, I'll send them to you.Bill, the Cosmicar line was apparently bought by Pentax, I don't think that name is used anymore. The 8.5mm and 12.5mm do not cover the sensor. The 8.5mm actually extends a bit too far into the G1, it will conflict with the black baffle inside the sensor chamber. If you look at the 8.5 on the left, you can see there is a retaining ring that extends beyond the c-mount threads. Any lens that extends that far is a no-go, I think I can get the 8.5 to work by shaving a tiny bit off the retaining ring.
If you send me your Tevidon and adapter I can machine them for you and align things so the focus scale is up.
The Tevidons have apparently been snapped up and are no longer available for $40. Someone else has them for $100 now.

Ah, so Bella and Cooper on the little Pentax. What's your overall opinion of this lens, then - worth a bite? (pun intended)
I realise I must seem thick as I'd seen the picture of the 4 lenses already of course. The thing is, there seem to be more than one lens by the same name out there that are radically different to each other - namely, your Cosmicar 8.5mm f/1.5 isn't my Cosmicar 8.5mm f/1.5! So I was just making doubly sure.
I went ahead and ordered the Pentax 25/1.4 from B&H the other day. As you say, the prize and size are both a tenth of the monstrous Panasonic 25/1.4. I expect it to be of lesser quality but not down to a tenth...1. It's extremely tiny,
3. It doesn't cover the sensor in 4:3, but it does in 16:9. I don't find this a problem as I like 16:9. Doesn't appear to have corner smearing except on 4:3 which is really a coverage issue, not the typical rangefinder lens smearing.
Monza, have you recieved the adapter? How do you like it?It just became available a couple of days ago. I have one en route...will be happy to report when it arrives.
