I have 3 very nice old Telephoto lenses for an old Pentax K1000 that doesn't work good anymore, color is shot. So my wife has a new Panasonic Lumix FZ18 camera and we thought we would try to get the lenses to work on it. Considering they are 3 very nice lenses and the Lumix really doesn't have many options for professional lenses that I have found :(

So we bought a Fotodiox Lens Mount Adapter, Pentax K (PK) to Micro 4/3 Olympus PEN and Panasonic Lumix Cameras.

Of course that doesn't work out of the box :). So I have a friend that has a machine shop, we took the far end of it and made threads on the outside of it and flushed out the inside so that the lens of the Lumix internal lens would fit through when we turned it on. Worked like a charm, we use a plastic adapter that came with the camera to take it from a larger size down to the outside ring size of the Lumix.

That works great. Problem now is that when we turn the camera on it shows a tunnel! :( I figure because the old Pentax used a mirror and didn't have its own lens, while as this camera has it's own built in lens so doesn't know what to do.

Is there anything we can do, maybe another adapter or filter, to make this work now? I hate to see 3 very very nice lenses go to waste since I can only get $15 for 'em on ebay.

Not related to your question, but I'm curious what "color is shot" means relative to a K1000, which is a film body. –  Blrfl Oct 12 '12 at 21:06
    
As an aside, good K-mount lenses still carry a bit of value with them — they'll work on Pentax DSLRs as well as the still-popular K-1000. (There are still a few people choosing to learn on film, and some old farts like me still happily using garage-sale finds. Sure, you can pick up a K with an SMC 50/2 for the price of a cup of coffee, but the cheap longer/wider stuff tends to be department-store branded 3rd-party "off-off" brand stuff.) If you've got Pentax or good Vivitar glass (Series 1), it should still be worth something. –  user2719 Oct 12 '12 at 22:06

So, you're right: you're foiled because the Lumix FZ18 isn't an interchangeable lens camera. The adapter you link for is for Panasonic's Micro-Four thirds cameras, like the Lumix GF1, which do use interchangeable lenses. It kind of confusing for Panasonic to use the same branding for both those cameras and their attached-lens models, but there it is.

The adapter is designed to go where a "native format" lens would, and in this case simply to adjust for the physical connection difference and the different distance in the distance from the back of the lens to the film/sensor plane — it's bigger in SLR designs than for mirrorless cameras, which is why you can get an adapter like this in the first place.

But with your camera, there's already a lens, and while it's possible to get "secondary lenses" (like this) meant to attach in front of another lens, you can't just take another lens and do that. It might be possible to design an adapter with adjustment lenses of its own so that you could attach DSLR lenses, but the results would just be a novelty.

So, there's not much you can do except hold on to those lenses until you do have an interchangeable lens camera. Pentax makes some nice modern ones with which they'll work like a charm, and you wouldn't need an adapter. Or, you could get a Micro-Four Thirds camera from Panasonic or Olympus (or similar-but different NEX and NX cameras from Sony or Samsung) and use an adapter. There are very many great old Pentax lenses out there, so K-mount adapters are common.

Hmmm, he said new FZ18 and that camera dates from 2007! Something is odd here... And good catch! I didn't recognize the model and skipped on by the question. –  Paul Cezanne Oct 12 '12 at 23:40

@PaulCezanne Yes, it's NEW! We live part of the year in Guatemala, C.A. and here it can be purchased BRAND NEW from Panasonic, my friend works there as the head of the IT department. Maybe in the U.S. you cannot but here it can be purchased brand new. @ –  jfreak53 Oct 14 '12 at 23:43
    
@mattdm Thanks, I was worried about that. Oh well. Another new Cam is not in the budget now ha ha, so we will stick with this for the time being ha ha. Thanks for the info. –  jfreak53 Oct 14 '12 at 23:46
    
@jfreak53 I hope you got a very good price because even new in the box it is somewhat dated technology. Not a bad camera for its time (and class of camera) but technology does move fast. In any case, hold on to those Pentax lenses. –  mattdm Oct 15 '12 at 1:14
    
(If you paid more than about $100 US, you were ripped off.) –  mattdm Oct 15 '12 at 3:23
