This sounds a bit overkill. This thread is about avoiding tiny scratches and not about creating huge ones. I don't think that anybody is serious about taking a Dremel to their camera.

So right! I once got a 30 day ban at DPR because I advised a guy to clean his sensor with a magic wand at the car wash...and he did. The only bigger fool than the guy that ruined his camera was the fool that banned me for being a bad influence on the mentally impaired.

Looking at those in a full blown panic here over a little scratch, I have to believe that guy from the car wash might be in there somewhere, so it is our duty to protect him from himself and his Dremel tool or metal grinder.

Regards!

Okay, now this thread is getting scary.
When Rupert's posts are the [comparatively] sensible ones the thread has gone over the top.
You know...that is pretty scary, even to me!

Sadly, yes they are. They simply don't understand that once the hard steel of the Sigma mount has scratched the K1 - it now has the clearance it needs and will do no further damage to the camera. The fact that this thread continues to lengthen ought to be enough to tell you that people don't understand what is going on.

It's a crock anyway, they have screwed up in the past. The first Pentax body to implement that hideous prism overhang was the K10D from recollection.

That lovely bit of jutting plastic wouldn't allow the A*200/4 macro to rotate to portrait mode whilst the pair was mounted on the supplied tripod mount as the set screws on the mount collar collided with the prism overhang, they didn't offer to fix that. It also made using the aperture ring less than comfortable.
And hey... you have the same issue with the K-1!
That´s the only thing with the K-1 which makes me feel bad about it. But that´s really annoying for me!

I just did a little walk with Google images and see what you mean.


Steve
I did some quick and dirty shots, hand held, kit lens, available light (window) so they are not very sharp:

The K-mount adapter appears to me to be thinner than then on the non-auto bellow. And you can see the foot on the standard. You could use a battery grip but only if the rear standard is at the end. You have to position the standard at the back to turn a DSLR to portrait mode regardless.


Here I loosened the set screw and turned the body as far as I could until the corner of the mount base hit the foot. MF cameras have a rounded base without the corner. Work around - remove the camera and adapter from the bellow and reposition. Or add a short extension tube to the body. This is recommended BTW with the screw mount Auto Bellows.


There may be enough clearance up top on the K-1. One could always use a short extension tube between the adapter and the body.

A dremel tool will cause a thousand times as much damage to the camera as mounting an interfering Sigma lens.
The Dremel tool has a long history here in the Forum. A little searching and you will find all kinds of Dremel tool hacks that can enable other Mfg. lenses to fit on a K mount body. Rather than taking a grinder to your new Pentax K1, why not grind down the offending part of the lens? Those of us who got burned with the Nikon IX lenses, made for their APS film cameras, figured out the Dremel tool fix fairly quickly and removed the offending piece of plastic that hit the mirror on DSLR's.

I believe the original comment was made in jest. If you look at the K-1 cutaway photo I posted the shell at this point looks only to be 1-2mm thick. Not much material to work with. Beyond this looks like another shell, bracket or PCB. I wouldn't take a bit and cut away any material in that area.

If I had a K-1 (which I currently don't), I wouldn't worry much about leaving a tiny mark on the camera body. However, I'd worry a bit about what that slight torque or tension does to the mount of the camera and the lens and also whether it affects the electric contact between the camera and the lens. But perhaps this is not a major issue, or is it?

I don't know if this has been posted but Sigma offers part replacement to prevent lenses scratching Pentax K-1. I hope you guys will be happy.

This forum has seen worse. Lots of people have been modifying or destroying their lenses and cameras in many creative ways here.

People have even covered their cameras with dust and dirt!! Or shown themselves using their cameras near sea-spray!! Without using UV filters either !! All those people need to be banned.

People taking a tool they own and using it on another tool they own, oh the humanity!

Seriously though, I also want to add that Adaptall-2 mounts, and their matching mirror lenses (eg. 55B) are no problem.

So the fun part of this, before D-FAs, I was eyeing the Sigma Art lenses as the next LBA target. Now I can safely wait until they produce the new batches that are K-1 safe. There will be a whole new market, and every Sigma transaction will be accompanied with a clarification: this lens is made after K-1 Sigmacalypse, it's safe on K-1!

A+

I'm quite serious, no doubt after the first lot of modified lenses come back from Sigma there will be a chorus of cries about how repaired lenses don't focus properly any longer plus I simply can't afford to have half my lenses away being modified as a working photographer.

The body mod would be quite easy and safe for anyone who knows what they are doing (much less chance of damage than putting WR bodies under running water for instance), I certainly wouldn't recommend doing it that way but it suits me.

I promise to post pictures.
