  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Modular Dragon OLPF sneak peak

Don't know if it would work, but…

perhaps a magnet mount, kind of like on the power connection on the MacBooks… Seems like a fast, secure and flat/even option.

Just an idea…

my original idea was magnets but the engineers were VERY quick to rattle off a dozen reasons why that was a horrible idea... most of them already listed by you guys here :)
 
Will there be a OLPF thats a mix between the old and new OLPF in the works?
 
Is it possible to make the screws captured screws? So that they don't slip out and bounce around on top of the sensor? I can't count how many times I've lost a tiny screw into a box.
 
As impressive as it seems, I just wonder if this is supposed to be a permanent fix, or a more temporary solution. I confess that was expecting some color science/future build improvement allowing nice skin tones, no flare, low-light capacity and noise-free images, all in one...
 
Pinky orange odd looking image, like wearing cheap sunglasses. Strange colour shift and aliasing... also more internal reflection of the back of the lens and after not long at all nasty DSLR style dust specks right on the sensor.

Oh and you probably can't wind the backfocus screw far enough to hit infinity on most lenses.
 
Also Raises hand....

Out of curiosity.... What if you shot with no OLPF? What would happen?



Seriously though. Any of the blocked light, like IR, would come through and effect the image. Also "Clear" would likely mean it's the most unblocked light, meaning it can see further into the dark potentially. Also, if it's a true optical clear and no AA effect you will get real sharp images at the cost of perhaps seeing aliasing and color moire. However, for super detailed work it would be cool.


#edit. What John said. Heh.

Sounds awesome. Lets do that.
 
Hey Jarred, any plans to make a LOWLIGHT version of the NEW OLPF?

Ie an ALT of the NEW OLPF (with improved skintones, better tungsten, better flares, ΙR etc)...but optimized for 2000 iso, etc?

That could be fantastic also!

May end up looking like a nice combo of the OLD and NEW OLPF.

best.

+1000 on that.

went through that option as well.. unfortunately that means that the whole thing would need to grow outwards to accomodate the captured part into the lens cavity and would interfere with lenses that have a long final element.
 
Is there such a thing a screw whose shape under the head matches the pitch of the thread? (so there is a notch with height to the thread pitch)

The hole that the screw would be placed in could have a inverse 'step'.

This could used to create an exact Stop for the screw (no torx screwdriver required) / as a obvious hard stop would be encountered.

Make sense?

Whatever it is it has to handle the wear and tear of a rental house times 10. Screws with a long wearing coating.

It it would be cool if it could be done with a top and bottom lever that when recessed pulls it tight and then is sealed an flush mounted.

four levers that hold it tight. No screwdriver would be great. Screw it in once and the levers always do the work.

Battistella

a high tech version of this which acts as a mounting guide when open. Then, four snaps and it's sealed shut. Probably needs to be invented though...

If I understand you correctly this won't work because to get the right torque/tightness every screw hole receiving these screws would have to start their thread at exactly the right angle. Not a practical/economical solution.
 
I can see correct torque, avoiding over tightening and a great tough case to protect the spare OLPF frames from being bent being rather important for maintaining the OLPF parallel to the sensor!

Maybe a tiny expanding washer that breaks before anything else as a warning of over-tightening.
 
I think the term maybe something like Nord-lock or Wedge-locking.

I don't have any experience of these.

They may however provide a positive 'stop' / avoid over tightening.

Not surprised to hear the magnet mount brought too many issues with it, just hoping…

On a related note could we use screwdrivers with magnetic tips? Would the material/coatings the screws are made of stick to a magnet? Would having the magnetic screwdriver in the area during swaps be a problem? I like the idea of putting the little screws on the screwdriver tip first, then going for the screw hole without trying to get another finger in the space to hold the screw in place.
