Adaptors

Is there such a thing as an adaptor for Pentax lenses on a Ricoh GR camera??. I'm looking to lose some weight (K3ii K1) sometime in the future and I have lots of lenses so it would be great if they could be used on a Ricoh griii. Instead of having to buy all new lenses.
This is just a thought for the future and not immediate.
CHEERS Vic.

I don't think it's possible as the lens on a GR can't be removed. It would be very awkward to say the least, especially as the adapter would require a significant amount of glass to adapt the image from the K lenses.

For this situation it might be worth moving to a lightweight mirrorless system with cheap PK adaptors.

Vic, the GR's only have a fixed lens! Your only solution to your losing weight would appear to be to cut down on those chocolate bars!
There are lighter Pentax DSLRs with the the K-S1 being the lightest AFAIK or find a K-01 which is all of 3 grams heavier.

Thanks. I thought the GR had lots of lenses. I think I got it mixed up with the smaller Pentax cameras. Thanks anyway.

PPS. I now think I got it mixed up with the Pentax Q.

Now the question is. Is there an adaptor for the Pentax to Q cameras?

Yes there are third party ones available with aperture control and there is the Pentax Adapter Q to K which includes a mechanical shutter in addition to the usual aperture control.

From these the third party ones do a great job and don't cost too much. The genuine adapter costs a whole lot more and is more difficult to find. It also has a tripod foot which makes it more stable when mounted, and probably also protects the Q body a bit more.

Using any of the adapters with the Q is fiddly and there's no auto focus available with them either. The standard lens for the Q is 8.5mm. Any K mount lenses around that focal length are pretty bulky and try and go wider! TBH it's best to stick with Q lenses on the Q, they're light and designed for the camera unless you're into experimentation and can easily manually focus lenses on the rear screen (they're not TTL.)
I'll re-suggests the K-S1 as the lightest of the K mount cameras that does most of what a K3 can do. Nothing wrong with the Q either only K mount lenses with it are not wholly suitable.
Have you considered the MX-1 ? It's got the same size sensor as the Q, similar in use to the GR only with a reasonable quality moderate range zoom lens (as opposed to it being a compromised super zoom.)

Despite my comments regarding the adapters, I completely agree with John's comment above and also recommend a smaller K body. The K-S1 is near unbeatable if you just want a small cheap body with great IQ. Unfortunately, quite a lot of people think the same so they can be a little tough to find.

The MX-1 is a good option too, again a bit tougher to find.

Have you tried the K-30 or K-50?

There's a mint K-S1 on eBay for 205, 1800 shutter activations.
Lots of gear - but not a lot of idea!

One decent looking one on Facebook for 135 in Shrewsbury.

There a several mirrorless cameras with adaptors available to take Pentax Lenses, which raises an interesting question, would you be able to share picures on this forum if they were taken on another camera but with a Pentax lens

As for the Q, having just aquired one myself I have to say lovely little camera, you don't even know you have it round your neck, pain in the ass seeing the LCD in bright light though. Can't wait for my cheapo third party adaptor to arrive so I can try my 50-135 DA* on it.

As for Q lenses, the 5-15mm seems readilly available but the 15-45 is like rocking horse dung, unless your prepared to order from Japan and stump up the import duty.

I have owned the K-S1 and K-30. K-S1 is very fragile/made of light thin plastic, but IQ wise is epic for the price. K-30 is much better constrution/weather sealed, but I wouldn't go near that again (with it's aperture failure issues) if you paid me, or accept the idea that one day it will be for manual aperture control lenses only.

Light 35mm lens on the K-S1 is an awesome bundle. Uncomfortable grip and tiny burst buffer, but fun for group shots with the flashing lights countdown counter.

Vic, from your interest in the GR and the Q, it appears that your aim is to lose a lot of weight. Perhaps consider a body such as a Sony A6000. It has nearly half the weight of the K-3, adapters for Pentax K to Sony E are easy to find, you retain the image advantages of a 24 MP APS-C sensor like the K-3ii, it is also a well-featured camera in other aspects, and can still be bought new for under 500.
