Looking for full frame alternative to K1 for use with vintage glass

Thank you everyone for clicking on my thread!

I currently only own aps-c bodies, but I would love to use some of my older primes (K mount + M42) on a full frame digital body.

However, while the K1 is almost exactly the camera I want, I simply cannot afford it right now. Used market prices have spiked for higher end gear and Pentax alternatives do not exit. So the only thing I can do at the moment is to look at other manufactures older offerings and get a K1 later. Or wait it out, but that is no fun at all.


Are there any cheap options that I should consider?

My goal is to enjoy the process of taking pictures with manual lenses, being creative and feeling involved, and maybe do some portraits. Not so much photographing moving objects. The best image quality or highest megapixel number is not needed. Video capabilities are also not needed. Instead, what I care more about is usability with said old lenses, for example being able to easily adjust exposure when stopping down without having to fiddle around in menus, having a big and bright viewfinder that ideally offers some sort of focussing help, maybe ibis and preferably a bigger body with a deep grip over a small one. To give you a better idea, my K-50 almost feels too small for my hands.


Nikon is propably out of the question due to adaptability reasons. Sony has tiny bodies and is still a bit too expensive for what I am looking for.

So far I came across the Canon 1Ds mk i/ii (Big pro body, lots of af points that could hopefully help with manual focussing?) as well as the 5D mk i/ii (Even cheaper and / or better iq / dust removal).

Would these bodies be good options for me or should I be looking at something else?
What have other people or maybe you been using before the K1 was available?

I am glad for any helpful advice.

Do you have Pentax aps-c bodies now?

Using Pentax K-mount lenses on Canon full-frame bodies usually means removing or cutting off the aperture control lever on the lens which could otherwise strike the mirror on Canon bodies. This severely affects the lens functionality/usability on K-mount bodies. It also lowers the resale value of the lens. This is not a problem with M42 lenses.

My advice would be to save up for a used K-1 or full-frame mirrorless body. That way you won't have to modify the K-mount lenses and continue to use them with full functionality on Pentax K-mount bodies - DSLR and film.

Whatever you do, don't buy a Canon and cut off the aperture lever on your lens like other people have done.
(The mirror hits the lever and can break the camera, that is why they do it. )

The Sony A7 may be more economical- but it's hard to beat the shooting experience with the K-1 IMO.

Don't assume access to all those AF points or even focus confirm when using an adapted manual focus lens. Consider too that those Canon models are pretty ancient and that the prices reflect their age and capabilities. As for Sony, I have been been tempted by Sony at times, but even then would not spring for lower than the A7II. If a lightly-used A7II or even an A7 are too much of a stretch, then a good solution might be squirreling money away for awhile to save for that K-1.

FWIW, I do my FF work on 35mm film...

Save up for a K-1. There were some listings a few days back in this forum (the Pentax Marketplace). Not sure if these are still there. Maybe in your price range??

Good place to keep an eye on.

Oh, that is a good thing to know! I am already so happy I asked.
Most of the lenses are for K mount and I will certainly not do modify them.
I currently don't have M42 lenses, but have some in mind for the near future.

So I guess I will have to either find a very good deal for an A7 or save up my money.


Thanks so far!

Film may be another option if you'll keep your apsc kit and plan to use sparingly. That's what i did before getting the k1ii, amd still shoot film.

Any full frame body is going to have a significant buy in cost

Consider renting if possible, I rented A K-1 several times before I could afford to purchase a used K-1 from a PF member.

I actually use two Nikon D-700 and a few Nikon lenses, and the cost is low, and this camera and the Nikon AI lenses are very good. (The two Nikon D-700ís and two Pentax K-5ís are my theatre photography equipment.) Probably $400 for D-700 body. I would think a couple of older AI lens, such as the 35mm f/2.8 and 105mm f/2.5 would be about $200-$250. The choices w/ Nikon AI lenses is quite deep and broad. Even a PC 35mm f/2.8 lens is not very costly (I believe mine was about $200).

I wouldn't go for the Canon's you mentioned. Even the 5DmkIV is no match for the K1 except in video. So, Sony I think is the only good option---but yes the bodies tend to be a bit small and cramped (I had a Sony A7R---great camera). Also, while the ability to adapt lenses to the Sony's is great and sort of revolutionary, it's clunky in the end.

Maybe sell a body part? You could get a mint K1 or new K1mkII and have a good bit left over for another lens or 2 or a great tripod and head. Seriously, though, just wait for the prices to come back down. Supply chain problems have made the used markets for all sorts of things soar.

The Sony A7Riii I have and the A7Rii before it work well with k Mount adapter lenses, but that isnít a big deep grip camera as you said and those models arenít cheap. The Pentax Film cameras and a good scanner might be more aligned to your needs but film processing isnít free. Having used a k-1 for a month I did get the impression that the grip was fantastic. Maybe sell some other gear?
