Hardware and Accessories / Re: Jammed focusing on old lens (any advice)
« on: August 14, 2018, 05:20:15 AM »
    What's the status of your lens? Any luck? I hope it's possible to fix on your own.

Was just about to put an update here that I am out of ideas for getting that ring out, I can't get a good grip on it.
I even made my own silicon ring to the right size and couldn't get it.

I'm not sure if that outside ring can turn or not or if it's screwed in place.
I'm theorizing that the inside ring got tightened, then the outside one which basically acted like a second nut, locking them both or at least the inside ring in place.
That's if the outside ring can be unscrewed off without undoing screws under that cover ring with the writing on it.

Still not sure how to get either of them off.

Sorry to bother. Please clarify: is 0.7m a number which you read on the scale, or you have measured actual distance with you film camera (or the proper DSLR adapter)? Or just both?
If you are absolutely sure, then yes – rubber gloves and the smallest drop of liquid silicone grease (but be careful with the lens) will make the trick… But I’m not so sure)

0.7m is the number on the scale, I haven't measured specifically with the camera but it is certainly close to that.

“this one twists out” – it locks the front lens. Leave it as it was. Try to avoid sliding and rotating the front lens. Some people use fridge or smartphone vibration to settle the lens down, then tighten collar. Don’t use any force. If you get terrible lack of sharpness – it means the front element is a bit off.
The branded collar and the filter thread should be one piece, I can’t believe you ever rotated them separately (I can be absolutely wrong, naturally). But this part does nothing about focusing.
“bottom of this collides with the top of this” – yes, at this position the lens is focused to the infinity or even behind it.
So now you have 6 (or something alike) variants to screw these parts together. Screw it in to the end, screw a bit back as you need to set the synching thumb to its place (on the photo). Then check the focus with the camera (don’t rotate the ring while mounting, just check whether it’s infinity or not). When you find the lucky position and focusing works from end to the end – it’s time to look at the distance scale.
Does it show the wrong numbers? If so, find some small screws in it, release them. Rotate the scale to the correct position and fix it. If so, you are done.

So the bottom that collides with the top does not happen at infinity is the problem. It happens at 0.7m, I have to screw it off somehow, unsure how, maybe it's locked on with screws behind the trim ring.
I can untwist that middle ring and remove the first element at the front, it is not attached to the trim ring.
I won't need to customize the focus because there's a separate ring that defines the start and end point. However I can't reach the end point (the infinity point) because of that collision.

Getting traction on lens elements and retaining rings can be a pain. I have used rubber sewing thimbles or even rubber coated gloves with moderate downward pressure. This should give you enough grip to unscrew the ring unless it is glued.

I don't think it's glued because i feel like I twisted it on at one point just with my fingers when it was loose.
However I have tried a latex mat and also a rubber oring, but I think the thimbles sound like a better idea.

Have you disassembled it in two parts? Looks like it.
What you have inside of the screw helicoid now is multiple thread i.e. there is more then one way to screw the lens part in. So just draw some marks and check all the possible combinations. But there may be a kind of thumb (like that http://album.foto.ru/photo/2921784/ - possibly skewed) and parts of aperture control, which prevent the lens block from screwing in to the end. It's just a guess, I've never saw your lens.

I should get some pictures up. I did fix the problem I made, it's not  back to its original state of only getting to 0.7m. I have pulled those things picture out which is what syncs the screw focus to the end point ring that just twists back and forth. The thing that just twitst back and forth is fine.
I the the problem is, somehow, the top of the lens is screwed too far on, so that ring stops it from twisting further because it collides with the base below it.
The problem I'm having now is I both cant get it off, or the ring inside it which has all the lens specs on it. When I try to undo that the front lens element unscrews instead.

Does it have a adapter with correction lenses? FD mount, IIRC, needs a correction element between the sensor and the lens, to make it focus in the infinity.

I don't mean the focus in the camera, I mean the actual physical focus on the lens, it won't twist to the infinity state.

I've managed to do something because before it was only getting to 0.7, now it's only getting to 0.3, so I've made it worse...

The focusing is basically a giant screw, disconnecting the lens the twisty part can still click from end to end, macro to infinity, but the lens part won't physically screw all the way to infinity.

    You could try visiting a local camera shop, and see if there is someone knowledgeable in vintage lenses. You can see if they know of a repair shop for vintage lenses. You might be able to send your lens for repair at Duclos. Here is a link: https://www.ducloslenses.com/pages/services

The price of fixing a lens is usually more than a new lens :P
There's not much for option in terms of camera shops where I am in Australia.
I'll check out the youtuber.

I have a 24mm Soligor 2.8 FD mount. Everything works on it but I can't turn the focus to infinity, it jams at 0.7m, but can be turned the other way all the way to 1:4 macro.
I can't seem to figure out what is stopping it from turning any further, does anybody have any ideas or advice?

I need a couple of startup logs to diagnose a malfunctioning 550D, using this build:

https://builds.magiclantern.fm/jenkins/view/Experiments/job/startup-log-mpu/

Test conditions:
1) regular startup in M mode, without LiveView
2) same as above, but with the USB cable connected

Did anybody send these through? If not what is the process? Do I need to compile that build myself?

General Chat / Re: What's with electronic focus rings?
« on: May 28, 2018, 12:13:03 PM »
Yeah I think I'm going to have to buy the next 10mm up in price to get a USM instead of an STM.
I think my kit lenses are USM and my 50mm is canons noisey motor, but I don't have autofocus in video on the 550d anyway.

General Chat / What's with electronic focus rings?
« on: May 27, 2018, 12:47:54 PM »
I was super keen to get the 10 to 18mm EF-s lens until I just found out that the focus ring on it isn't mechanical.
It's one of those ones that spin forever which I assume has to communicate with the camera to communicate back to the lens.
Are they doing this with kit lenses for ef-s cameras as well nowadays?

General Help Q&A / Re: EOS Utility monitor with Magic Lantern
« on: May 12, 2018, 03:01:01 AM »
I never had a problem when I ran eos utility with magic lantern on my 550D.
And I did all kinds of combos including changing ML settings in the camera while it was hooked up.
Personally I can't understand how it would break the camera.

I do check up on this topic every time there is a new comment.
I will hopefully test the update soon and I will test before and after updating how 10bit video goes.

Maybe it would be better to try it before forcing an update?

Fair call :P

But yeah basically what I meant, that I would test it first.

Do I have to disable the bootflag first in camera to do the canon firmware update?

I'm thinking of just changing the first post to make it look as if 1.1.0 is the official version (not that I've tried it yet) but just as a force upgrade for everybody.
I don't see a point in there being two branches, and I don't see a point in using old firmware.
Thoughts?

i own a 550D also, it's actually 3:2, in all 3 resolutions (or 6 if you count the different qualities for each resolution)
you can add an overlay in the camera to view the screen in 1:1 but the photos will still be 3:2

Was anything happening with lossless compressed raw on 550D?
And I can't find the main threads on compressed raw anymore, was it ever applicable to anything less than 14bit?

Raw Video / Re: Rolling Shutter 1080p vs 720p modes
« on: December 31, 2017, 12:40:52 AM »
I wonder if the A and B timings are different for 1080p and 720p.

Also note that 1080p is 25fps/30fps where as 720p is 50fps/60fps.

Raw Video / Re: Shooting raw monochrome?
« on: November 08, 2017, 10:29:27 AM »
It's not exactly in colour, every pixel is in a value form which could be considered greyscale, but it knows which ones are which colours, red green and blue, but the bayer filter filters out the colours for each greyscaled pixel.

I was about to say The Red cameras released a version of their camera with no bayer overlay, but then I looked at the link first posted and I think that's what it is talking about.

I did hear something, it may just be hearsay, somebody carefully scraped the bayer colours off their sensor.
