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...
