Read up that the new Mac Pro is running open GL AMD graphics cards... Wouldn't this warrant a need for AMD support?

Myself, I just lost support for having Mac OSX 10.7... Can't upgrade to 10.8 because of the Mac Pro's build date. Still though it's a 2.66 8 core with 16 GB ram and a 1GB HD5770...

Received a prototype VAF filter from Mosaic Engineering yesterday afternoon. Went through a couple tests thus far... Feel free to download DNGs of the 50D with the prototype VAF...

https://copy.com/IOqlwsmWUi8i

Thanks. The company producing/inventing/manufacturing the filter is called Mosaic Engineering. They are headquartered in Pennsylvania, USA. The footage is shot in Phoenix, AZ. I am not affiliated with Mosaic Engineering or Magic Lantern other than I'm trying to put the two and two together... In my opinion, this combination is an incredible opportunity to create an appropriate production camera with high-quality imagery and feel-good results.

Enjoy!

...(Rending raw video results in background...) Video samples available soon.

The VAF is user installable.

The user pinches the AIF filter with a set of custom made tweezers that come with the VAF filter. Basically, the user places / pinches the VAF filter into the body of the camera.... Takes about 10 seconds to install.

Update: Canon 50D Mosaic Engineering VAF prototype...

https://copy.com/weRtPp0O9A0w

Uploaded DNGs in groups of 10. Each sequence is named according to the shot... Was at work all day and had to take a break to make this possible... As a result there is only one comparison shot with the VAF and without. Additionally, there are a number of shots displaying the filter using a Tokina 12 - 24mm lens. I only used 12mm and 24mm. Nothing in between. Looks like I may need to test additional focal lengths as there may or may not be edge-to-edge sharpness depending upon F-Stop and focal length...

Will know more during tomorrow's testing at my studios in Tempe, AZ. Will post more photos and quick video displaying the filter at work. This will be broadcasted on Vimeo & YouTube Friday morning.

Lots of Light! :D

Got the prototype 50D VAF in the mail today. Unfortunately, had to go straight to work... Still there. Anyway, brought the camera to work and was able to take quite a few shots here and there... Will be home in about 3 hours to process footage and upload images to ML Forum. Again though, they are not the original shots that I had planned to shoot with the VAF and 50D.

Will record video tomorrow morning. Plan on a better demonstration of the 50D VAF and proper posts on early Friday morning.

... Thus far...

Appears to be little to no light lose.

No moire and alliasing on Canon LCD screen. The Live View 10x mode image is softer.

The VAF may be adding additional flares from lights - Need to double check - - Noticed this with a Nikon 50mm F 1.4 Non-AI that had a 52mm UV filter. However, the Nikkor 50mm 1.4 has a rear element larger than the VAF filter. Didn't notice this issue with the Tokina 12 - 24!

The VAF looks nearly identicle to the T2i filter. Zuzukasuma may be right. However, I highly doubt it is the same product. Mosaic said that they built this unit specifically for the 50D sensor.

The Tokina 12 - 24 is no longer parfocal. Focus setting are different. It's almost as though the focus setting are reversed. Infinity is now macro and macro is now infinity. Will have to look this over again to confirm, though. I assume that every VAF filter has the same issue.

Finally, the electronic components work with the lens. There are no issues using EF electronic lenses with the 50D VAF.

... Anyway, can't wait to get home and process footage... Will conduct proper tests tomorrow morning with a Test Chart and more appropriate video shots such as a brick wall...

Plan on a video post and ML post on Friday morning... I will be reading posts and comments on ML. Leave some feedback and suggestions... We should share what we think. Mosaic says they want to hear how these tests are working out.

Just so you know, I have watched Mosaic Engineering's video posts on their website and basically plan to do the same tests. This includes post sharpening and non-post sharpening.

Expect images from video posted this morning... Remember, this is the prototype and not the final product...

Working with latest Tragic Lantern... Had an instance today where Live View on Canon was flickering with random colors (not during record) (lasted about 2 - 3 seconds)... Exposure Override turned on... 23.976 fps... Global Draw On... 1/48 shutter... Non-Canon 2200 mAh battery... Komputerbay 64 GB 1000X... Raw_Rec Module... ISO 800... That's about it other than the fact that the camera had been turned on for about 10 minutes before the flickering occurred.

Decided to press record even though the screen was flickering... Fortunately, when I pressed Record and Raw_Record was activated the flickering went away. Not even a single frame was corrupted during a 2 minute take... Nice.

Won't be recording again till Thursday... Just looking to help, if possible. FYI: Love how the black side-bars are gone! Headroom is now accurate to the Canon LCD screen. Maybe it's just me but the past couple Tragic firmware updates were a bit off from the Canon LCD (shooting 1584x892 and was cutting off the tops of heads even though the framing left plenty of headroom - like title-safe distances for headroom... Hmm?)... Anyway, thanks for the Sunday compile Andy600 and for the latest updates 1%. Can't say enough how powerful the color-depth and image appears!

Canon 50D Prototype VAF Filter Update...

Now have a tracking number, though the item has not yet shipped. Here is an except from Mosaic Engineering... "Return shipping of Levi Davis' 50D (...) including rev. 1 prototype VAF-50D. (...) please let us know how it goes! --MAV"

... Will post photos and videos for ML users and Mosaic Engineering review purposes.

I'm concerned with the 50D VAF filter interfering with the communication between the body and Canon AF / IS lensing as well as the ability of the camera to resolve detail. Do you have any additional suggestions that should be considered during this prototype testing phase?

Thanks for the 50D development! Looking to test out MLV... Wonder how the 50D will handle the extra info??? Thanks for the extra effort.

Decided to make up a quick tutorial for lensing on the Canon 50D. It features three lenses; the 24, 50, & 85mm.

... Definitely the kind of information every cinema photographer should have on the tip of their tongue. Enjoy.

I wouldn't count on the 128GB 1000X achieving full HD. I've got a Canon 50D and I was barely able to record 1582x894 continuously (purchased 2 and both had same issue). However, the 64GB 1000X will continuously record 1920 x 1023 on the Canon 50D. That happens to be the fastest the camera can write. Rest assure the 64 GB 1000X can record Full HD. Remember though that you will be recording Full HD on a 3x crop mode. That and you're only going to record about 12 - 14 minutes at most. Realistically there aren't that many card options in terms of cost, availability, and speed. That's exactly why the 64GB 1000x is future proof. Just plan on purchasing multiple cards to suffice for the limited recording time.

Have same issue in 5X. The CANON image (in 5x mode) is always at the bottom right hand side of the 3x composition.

_7D_

Shooting 1280x720 results in cropping into sensor. It will have a crop factor of somewhere near 2x. Basically a white box that serves as your framing lines will shrink inside of LV that shows you how much you're cropping into the image at 1280 x 720. It's certainly not the same as pressing the 5x zoom and recording a 1280x720 image, that would be a crop factor somewhere between 3x and 5x.

The reason we don't record 1280x720 in full-frame is because they skip more than two lines in the sensor readout. There would be so much moire and aliasing the image wouldn't really be appealing. However, from the perspective of cropping your image in camera and simply using the 2x crop sensor space, you'll be able to record a lot more footage than you would at full resolution.

abpcl:

You've got a great card to start out with. You'll be able to record at any resolution the camera can record. The card will last about 9 minutes in a 16x9 aspect ratio when using the full sensor. When in 3X mode the recording times and recording lengths are far less. However, if you're into optimizing you can nearly squeeze out a 1920x1080. However, I presume to say your 32GB card will last about 5 minutes in this setting.

The users have been reporting the do's and don'ts with this camera now since about the beginning of the Raw Module development. Seems the highest priority is ETTR (Exposure to the Right). It's possible to record at ISO 200 (the lowest sensor noise setting) and have a lot of noise in the image if the image isn't exposed properly. It's possible to shoot at an ISO 800 and have less noise than ISO 200 if the image is truly exposed to the right. Basically, you'll probably not want to shoot higher than ISO 800 if you're concerned with lots of noise. Again though, every time you shoot you'll want to expose to the right. What happens is the noise embedded in the video is nearly eliminated when you adjust the contrast, exposure, and highlight recovery options in post.

The camera goes through batteries pretty quick, about an hour at best using a 2200mAh.

The camera will overheat and negate your ability to shoot about 22 fps when shooting in high-heat situations (above 90 - 95 degrees).

If you're using Image Stabilization the only way to activate is by half pressing the shutter release button while recording.

For proper testing of the camera - - make sure not to adjust the color profile. I typically stick to Standard or Neutral. Then I will adjust the contrast up to about 1 or 2 out of 4 and also boost the color saturation to 1 of 4.
It's typically a bad idea to use a profile that acts like a color-correction filter because the sensor only records raw information. Exposing your image to the processed color-picture profile usually results in under exposing the image.  Remember, in post you want to have an image that is exposed to the right. If you're pushing your image to the right in post you're introducing a great deal of artifacts that could have been avoided in production.

The Canon 50D produces a great image. However, take special care when shooting video of sharp lines and finite detail (especially in the distance). The sensor is only capable of resolving so much detail out of a shot. If there is a great deal of detail in your shot I'd shoot off two shots. One of them the way you prefer and the other with a slightly soft image (some people say using a poor quality UV filter works and other's say to simply adjust your focus so that the image is soft.)

That's about it... It's going to take some time to get used to the rhythm... But hang tight and suddenly this ML page will start coming to life. There's tons of great direction and great wisdom on ML.

Seem to be having trouble with TL... Screen overlays such as Histogram and White Frame Boundary are always flickering; sometimes it stops when I activate the ML menu.

HDMI output problem with Unified and TL... HDMI output overlays are offset.

Here are two test examples...

1).TL - - Powered on Camera with the HDMI output connected to monitor and there are offset recording frame boundaries and also flashing overlays.
Results here

2). Unified - - Powered on the camera, activated LV and then plugged in HDMI. Here are the second results...
Results here

Got a call this morning from Mosaic Engineering. Mosaic Engineering is now creating the first beta 50D VAF. Should be ready within a couple of weeks or so... 

...Will test the VAF and post some video/images here on ML.

Mosaic Engineering stated that a number of shooters have contacted them to purchase the 50D VAF. Again, I'll have a beta version, but they have mentioned that their goal is to produce an alpha 50D VAF... Will know more later.

Thanks for the ISO test... Definitely keeps things in perspective when exposing to the right. I'm astonished to see how well ISO 500 is holding up. Thanks again.

I have a couple Canon 50D cameras. I originally purchased (2) 128 1000X cards to record. Both cards worked in camera with no troubles during the June 18th to June 28th builds. Unfortunately they weren't fast enough for the camera and I had to return them both. I've been running (2) 64 1000x cards since and these cards have been perfect.

By the way, I just received an email from Komputerbay stating that a 1200X card will be coming soon.

It doesn't say what size or anything... Guess that means it's a 128 or maybe a 64???
