Modules Development / Re: A new idea on a module
« on: April 27, 2021, 12:18:15 PM »
And if you ask me, I got rid of these "problematic" lenses, as I didn't like them anyway (EF-S 24mm f/2.8 STM & EF 50mm f/1.4 USM).

well...some of them are great actually, 85 f1.2 is a great example

First: There is a department for this -> Feature requests.
But don't mind that. Visit Scripting corner first and explore Garry's script repository, esp. DOFIS.
I think there may be a problem with executing scripts at shutdown/sleep but IANAP.

Yes, ArcziPL mentioned that, thank you for the reminder.

Modules Development / A new idea on a module
« on: April 25, 2021, 07:12:46 AM »
Hello, I am thinking if there is a module that automatically set focus distance to infinity so that the external focusing lens (50 1.8 stm, 40 2.8 stm, 85 f1.2 for example) will be safe for the older model cameras. (Just like what 6D2 or newer model does, there is a opinion in the canon menu that set the focus distance to infinity while sleep and power off)

Anybody think this is a good idea or there is one of these module exist already?

I don't see why not crop afterward XD
Cropping afterward will also give a larger tolerance on composition for me.

However maybe useful on video recording with prime lens like IDA said.

More likely to build a new camera LOL

Nice try

No. CF card memory and device modes (except IDE mode) are just based and backward compatible to PCMCIA standard.

In the same way as IDE / UDMA modes are exposing IDE interface directly on CF connector and require direct passive adapter, in first two modes CF card is basically a smaller PCMCIA card.

CF host does not need to support PCMCIA. PCMCIA support CF as it acts like PCMCIA.

And "card readers" others than CF are either emulating PCMCIA memory mode, or are just straight PCI (PCMCIA) devices interacting with OS, thus requiring device mode support and drivers. You won't find this on camera.

Got you, thanks ;)

The official ML source code has moved to Heptapod:

You can clone from there using Mercurial

Good to see this :)

General Chat / Re: Brand New 5D3 with kit Lens 24-105mmL F4 IS
« on: September 11, 2020, 06:15:03 AM »

In your situation and given this excellent price, I would definitely go for the 5D3.  I have some experience with that camera with ML on it and it really provides stunning quality results, especially in the high-resolution anamorphic modes whose quality is barely distinguishable from the 1:1  ones.  Furthermore, ML on it is very stable and reliable and camera never overheats with it.  The 24-105mmL F4 IS is a very good universal lens but it is a bit heavy and bulky and not very convenient for hanheld and gimbal work.  I would sell it and buy the 24/2,8 IS and the 35/2 IS lenses instead - pretty light and small and perfect for low-light hand held work.   My favorite lens for such situations is the 85/1,4 L IS.  It provides the most beautiful portrait video images that I have ever seen and is not so expensive like the R lenses for example.  For extreme wide angle shots, the 17-40/4L does an excellent job and is pretty light and inexpelsive too.

Get yourself the 5D3, put ML on it and you will never be disappointed!  And if one day the miracle happens and we have ML working on the 5D4 you can still replace the 5D3 with it.

The truth, I picked 5D3 instead of 5D4 is only because 5D3 have ML on board :D
A Canon DSLR without ML is not complete for me to say.

Do you know that 99% all the cameras have a max limit of card storage that they accept.
Don't be worry about this, the SSD I used is a MLC one from cisco @ 64GB

PS: There are something in the end of the previous page.

Sorry, but you are wrong. Those SSDs depicted on photo have completely different pinout than CF, it's called 1.8 IDE. I had one of those on OQO 01+, and still own adapter that converts CF pinout so you can plug it to replace this kind of "CF connector" drive. Their connector is also slightly different so you can't just force CF card into 1.8 IDE (and 1.8 IDE drive is wider so you can't force it into CF)

Also, let me remind you all that CF standard has three types of operation, one of them is IDE emulation. There are cards that don't support IDE mode, CF readers/controllers also need to support this mode / talk ATA to card.

I see, thank you for the knowledge.

That explains why the previous one made by deanziyangyu didn't works. However the socket in the front is the same as Compact Flash
I tear down exactly the same board deanziyangyu posted, the black part in the front fits into the case of CF card perfectly in the picture I posted (the fly-wired one). That is the reason why I was thinking they are the same. And yes, you are right. CF and IDE 50 are two different stuffs.

PS: JM20330 is a two way chip set not only can do SATA to IDE but also IDE to SATA

Few things need to clarify.
First, Canon 5Dmk3 (also include 5DS,5DSR,7D,5D2) are all using "Compact Flash" which is a type of SSD based on the IDE interface.
However Canon C200 uses "CFast 2.0" which is a type of SSD based on the SATA interface (which we used a lot on our computer nowadays)
In the same time, the socket they developed is also based on the SATA. As in the video send by gzillarocks, there is no chip set in between the socket and the mSATA.
The highest speed IDE socket can go is around 133m/s while SATA2.0 can support around 300m/s. Not to mention SATA3.0. SATA and IDE conversion need a chip set, not simply putting wires together. That is the reason why no one makes the adapter on the market since there is only a little demand on this. (Hey, professional cinema cameras are all have CF2.0 or even USB type-C installed :)

There is no Adapter on the market have the function we need, so we have to make our own :P
I am only an undergraduate freshman majors on EE, no experience on making the PCB.   But lets see how far we can get on this since I think it will work theoretically.

PS:Compact Flash can also being known as IDE 50(since there are 50 pins on it), I saw these kind of SSD before when my father was still using floppy. They have the exactly the same socket as compact flash do, just little bit longer and wider on the body. But people are not manufacture these drives anymore and because of the high selling price at that time, these kind of dives didn't sold a lot. So it is also hard to be finding in the second-hand market.

Hey Aperture Science- I'm really hoping that you can find a way to adapt from CF to SATA, or CF to MSATA, for cameras with Magic Lantern. I will definitely be following this forum to see how you progress! I did find this product online that works with a Canon c200, but I'm not sure if this device can work on a DSLR with Magic Lantern or not. Either way, I wanted to send you the product link so you can check it out and maybe it can be helpful to you:  - The product is called SolidPod

CF cards are so much more expensive than SSD's, and I've found forums on here going back to 2013 with people trying to find a way to adapt from CF to SATA, but without a lot of luck. Hopefully with the newer MSATA, or NVME devices it might be easier to create an adapter that works for Canon cameras with magic lantern.

I would also check out what RED did with their MAG recording devices. It looks like they are using some type of adapter inside the housing- that might be useful to you too.

Let me know if there is anything I can help with, I will be following along for sure.

Sure Sure, I checked this one long time ago. Thanks for reviewing.

CCTV lens
Since you need overcome the crop factor.

Okay, new plan.
I decide to learn how to use altium designer and make a PCB board for this.
No more stupid fly wires.

Unfortunately, I have no idea about CF and no time to go into the topic, but just quickly checked the pins with pull-ups.

Others (/WE, /CS1, /DMACK) should be plain inputs. Try at least to add a second, separate resistor for PDIAG. No idea what and when this pin does, if it's used in both directions in True IDE (sorry, really no time) but as a quick check it might be worth trying...


I think I should just connect every pins to pins instead of doing resister tricks. But I need to get some rest before doing it for the next time.
This one I spend two half days on flying wires. Really stabbing my eyes (each wires only have 0.1mm) lololol. But good to see LED are flashing. The red LED flashing means there are signals trying to read and write.

Those wires are coated with an insulating layer. Nothing to worry about.

The truth  ;)

This is what I get so far.
It seems working but it is not. What I am pretty sure is every wires are connected, but not sure they are connected correctly.
I followed the picture I posted in the last post and connect the rest. The computer is still not reading the card but the LED seems start flashing.
Maybe it is time to make a PCB board for this? I only used one resister instead of four.

Not sure what does that flashing LED means. If you know, please help :'( For this, I didn't use any external power supply.

Still making my own cable. Giving out more pinouts

Giving some more pinouts here.
What I am thinking is disconnect pin 38 and 39 and connect the power in the end so even if the power supply have problems, it wouldn't damage the camera.

Health check-up: have you enabled LiveView in Canon menu? It's disabled by default in 5D2 firmware (also in 50D).

Refer to long installation guide:

Edit: this is a Canon quirk (their default settings are not always the least surprising), but working around it might be very easy - we could enable LiveView after ML installation. Or at each startup - are there any 5D2/50D users who prefer the LiveView permanently disabled?

The truth LOLOLOL, I can still remember I was so confused after I set my 5D2 into factory settings and cannot turn on the LiveView.
Very funny LiveView button is disabled by default in 5D2 and I think that is why they add a button just for turning on the LiveView in the future models.  :P

Camera-specific Development / Re: Canon R5
« on: August 14, 2020, 07:27:58 AM »
In case of R5 it's not even SATA (CFast), but Canon skipped directly to PCI Express / NVME (CFexpress).

Are you sure? CFast to SATA do exists, as CFast uses SATA protocol. But CFexpress is NVME (PCI Express), that's why I wonder if there will be similar trick possible.
But even if possible - probably a little harder due to PCIe signalling requirements.

By the way - there are three types of CFexpress cards - A, B, C. They differ in physical dimensions and number of PCIe lines. I can't find any information which one will be supported here, but I bet for type A, which is physically similar to SD card.

Of course SATA line do not contain the pcie lolololol, I was just saying there are things like that by change pcie into SATA ;)
