Fit your lens, mark the interference zone, remove the lens and relieve the lens with a nail file. No big deal.

Is Chrysler responsible for not designing their new Jeep body to accommodate those old wheels and tires?
Meanwhile, GM and Toyota may keep their designs spacious and third party friendly, and parts are cheaper, so the next upgrade is a Toyota.

Or in this case, Canon or Nikon. Just look at how flat and roomy the 6D or D810 mount circle seems compared to the cramped and lumpy area around the K-1 mount ...

And how much bigger are those bodies compared to the K-1?

Or put some black electrical tape over the area that would get scratched?

Always best to relieve contact points that shouldn't be there. It adds a force in abnormal situations such as dropping or bumping the lens to the body to areas that weren't designed for it. In severe situations the load can accelerate wear on the bayonet ring, although this doesn't appear to be the case here.

Lenses I generally keep, cameras I don't, so it's the camera that gets modified for me.

My dremel work tends to end up with an unwanted tail somewhere! I wouldn't trust myself not to pierce the skin.

I can see myself loading it into a press with a nice cutt-off disc and producing a neat little scalloped cutout much like the mystery one above. A good vac and a little touch-up paint and she'd be as good as new, just better.

Hardly bigger at all in the case of some FF's, as already posted in page 2 of this thread:


Body size isn't really the issue.

Looking at the cutaway there's plenty of room to get the Dremel to it.

I don't see the "plenty of room", things are quite tight. Fix the nonconforming lens, not the camera.

And the Nikon D810?

Does Canon/Nikon have a screw drive, Aperture control lever mechanisms and IBIS to cram into the body?

Given the shape and position of the pentaprism there isn't much leeway for a nice flat area.






Don't judge a book by its cover.

The worry that I have is that - what is admittedly a relatively minor issue - could easily get blown out of proportion. For example, buyer goes into a shop.

Buyer: Oh, I am interested in the new K-1. What lenses are available for it?

Shop: Well, Pentax have three new lenses released, a handful of older lenses that are still in production and then a large number of lenses that are no longer made.

Buyer: OK, so not many of these 'designed for digital lenses' I hear so much about?

Shop: No, but you can mount Pentax's DA lenses on it.

Buyer: Hmmm, I see. So what about other makers, like Sigma?

Shop: Well Sigma has just issued an advisory saying that some of its newer lenses may damage the camera.

Buyer: OK, well thanks anyway. Think I'll shop around.

The point being that unsympathetic people can blow this out of proportion and anyone with existing Sigma lenses who don't frequent forums but may see the note from Sigma - either like above, or by reading it on Sigma's site - and may well be spooked.

There are also potential implications for other more exotic lens designs such as tilt and shift lenses.

The main issue is that you don't want a narrative developing which is: "there is a design flaw on the K-1". Which we know there isn't really, just an oversight regarding a number of lenses made by other manufacturers.

It only needs to be a similar size to the mystery cutout above where the Sigma lenses rub, no great drama.

But there was enough leeway in the K-200D, K-x, K-5, K-5II, K-3. K-3 II ...

The K-1 design team should have kept a few mm spare above the K-mount, even made a nice empty circle around the lens mount like they did in the K-3/K-5/K-x etc.

In the good old days, they left plenty of flat, vacant space above the K-1 mount ring.

I see now. It took Pentax 16 years to resolve the Y2K bug.
