Thanks for your input guys. Just to clarify, the 1 hour 15 minutes of continuous recording produced three files with movie restart switched on i.e. ( two 30 min and one 15 min file ).

However, if the quality of CBR 0.4 footage lies between unusable and stock, it is hard to notice without any proper testing. Is it possible that just like increasing the CBR to above 1.0 is supposed to increase video quality, in reality, (according to most of the forum topics on the subject), it is not noticed by most people?

Sometimes in our quest for the best, much time can be spent in doing so when in reality, it cannot be perceived by the eye, or in the case of audio sampling rates, by the human ear.

What I was really hoping for was someone who has done some testing with side by side comparisons of footage shot at CBR 0.4 versus Default 1.0 and higher.

Hi everyone,
   I recently tried recording 30 minute segments by lowering the bit rate to 0.4 and using movie restart while monitoring the CMOS temperature on my Canon T2i. I did not notice any apparent difference in video quality, and during the 1 hour 15 minute of continuous recording, the CMOS temperature remained at 12C - 53.6 degrees Fahrenheit.

Note: While recording at the default bit rate of 1.0 at the same location, same time, and same approximate ambient temperature, the CMOS increased from 12C to 17C - 53.6F to 62.6F

  Can someone who has done a little more testing of image quality and CMOS temperature while recording at 0.4 give me some input as to what you have found.

Thanks

Malcolm,
  Focus is not my greatest concern because  I use a Z Finder 3x, it just takes a little longer to achieve. But my greatest challenge is getting correct exposure. The cameras exposure meter is not very accurate when using a fully manual lens. I find that I have to over expose to get my shots looking decent. Of course, that could be my lack of experience as I jumped right in to the world of manual mode and manual lenses before I had really mastered anything else, but I'm loving it. My next purchase will also be the 85mm Cine.
   Let me know how things go after you've had time to try out your new lenses, I'd appreciate any tips.

Peter

Thanks for the tip Alex. However, I still need a little more clarification in order to better understand how to proceed.

I've just taken a few shots in Manual still mode at f/3.5, 1/48th and ISO 1600 and had the following results.

Exposure Override   (Off)    Display is dark
                                        Actual shot taken is brighter (more exposed than what the LCD screen shows)
                                        But meter shows -2 underexposure
                             (Auto)  Same result as being in the (Off) mode
                             (On)     What you see is what you get
                                         But meter shows -1. 2/3rd underexposed
                                         Histogram also reflects meter reading of underexposure

The Histogram shows underexposure in all three modes. Is their a fix that will enable the meter and the Histogram to show correct exposure as well as what you see is what you get?

Thanks

Hi Everyone,
  I have the Canon T2i 550D with ML loaded on it and have just purchased my first fully manual cine lens, but I am experiencing some issues with exposure.
  In Movie mode all seems well. However, in still mode (I always shoot manual mode ) the LCD screen is very dark. I located some discussion concerning this which advised leaving the camera powered up when you change lenses, but this did not work. I was at one point (while fooling around), able to get it to work only to see the same problem return when I powered down, then up again. 
   Can anyone enlighten me as to a possible fix for this problem. Thanks

Hi Everyone,
I've just purchased my first fully manual lens and am experiencing some issues which I may elaborate on if I continue to have a problem. However my question is, when in movie mode, ISO 200 shows up as 200ov. What does the letters "ov" mean?
Thanks

Thanks for adding the link Alex. I initially intended to do the same but felt it might be considered inappropriate to direct supporters of this forum to another website. I have just re-checked photonotes.org and though permission is given to print or copy for personal use, I unintentionally overlooked the part where it says it is not permissible to include this work on other Web sites.
 
My apologies'.

Thanks for your input, this is some of the information I have been looking for. I don't know if I am allowed to do this but I also found the following information from a very reputable site (see below) which may help others considering manual lenses.

I'm a little confused. If there is no chip in the lens which allows the lens and the camera to speak with each other, how can you set the aperture in manual mode in the camera when you have to physically set the aperture on the lens yourself. This would be a case of you doing one thing, and the camera having to do another. That is unless you are talking about physically setting the aperture to a certain value and again going into the camera and setting the aperture in the camera itself to that same value so they are one and the same.
   What am I missing here?

Hi everyone,
   At present I have the Canon T2i with the 18-55mm kit lens and will shortly be ready to upgrade to a better lens. One of my choices will be the Canon EF 70-200mm f/2.8L USM Telephoto Zoom Lens which will leave the gap below 70mm to be filled in.

   Well, Samyang/Rokinon has recently come out with three new cine lenses, and I am tempted to buy the Rokinon 35mm T1.5 Cine VDSLR Wide-Angle Lens for Canon EF - CV35-C (see here http://rokinon.com/product.php?id=202 ). Optically, it is supposed to be comparable to the f/1.4 version and therefore seems to be a good choice as I have (for some time) been thinking about buying the Canon 50mm f/1.4. However, I have little experience with "f/?" stop lenses let alone cine lenses which brings me to my question, which I'm not even sure how to explain, but I will try.
   
   How does a cine lens react with the camera, and consequently, what functions in ML will be altered or changed in the way they work or respond if a cine lens is used?

   I'm assuming that if the lens is "de-clicked" that full control of the aperture in now in the hands of the operator and that the camera can no longer be set in (any way) to have control of aperture. However, the shutter and ISO are still recognized and can be controlled  by the camera if need be. In light of this does the camera still sense aperture values when you are attempting to set exposure. In other words, will the display still reflect any changes that is made to the aperture, and how will it respond if you are trying to shoot in any of the "Auto' modes (though I prefer to shoot in manual mode only). And are there any other consideration that should be noted when buying a lens such as this?

  Note:  Phil Bloom gave a review of the photo version of this lens which can be seen here

Hi,
I went through all of this eighteen months ago but was unable to find a good solution and gave up. It never occurred to me that I could use ML for this purpose. Can anyone give me a few links to some affordable wireless RF remotes that would work with ML to remotely control movie mode?

Just felt the need to say, "have hope" I have a 550D which has the upgrade from 2.2 to 2.3 and everything I have tried is working perfectly, including the Magic Zoom. The solution to your problem may be much simpler than you think.

   Just prior to reading your post, I began to think about a couple of the points you mention. The first was that capturing the same audio on both the camera and the recorder would allow more efficient synching up later. And the second was that you could use the DR100 much in the same way you would use a Juicelink or Beachtech for better preamps to feed good audio into the camera.

   This, along with the other points you mention have given me a few more ideas on how I can use the DR100.
  Thanks a lot Led.

Hi Everyone,
    I've just purchased a Tascam DR100 MK11 and Tascam gives the following information on how to hook the DR100 up to a DSLR camera:

    (The separate line out and headphone out on the DR100 allows you to listen in headphones  while you send a copy of the signal to your camera to sync up later).

    When recording audio with an external recorder using and external microphone, why would  I also need to send a copy of it to the camera when the camera itself is recording the audio which can be used to sync up later? Unless the "signal" they mention is different to the "audio" which I mention, but I've assumed they are one and the same thing. Am I missing something here?

Alex,
After sending you my last post, I powered up my camera and tried again but it did not work. Just out of curiosity I accessed the ML user guide on the camera and went through several screen shots to make sure the used guide was working. Not expecting anything I double clicked the AV button and the Arrow/Set shortcuts appeared again and are working.
  I am unable to play around with it right now to see if the problem reappears as I have an appointment, but I shall do so later.

Alex,
I'm not quite sure what you mean, but if you mean (Duplicate the same problem), I'm not sure. I've tried another new SDHC card with ML on it in case something was corrupted on the first card, but it did not work.
  Also, the "AV" button is working normally in every other way, so it is not the button. I've also tried disabling the Arrow/Set shortcuts and turning them on again as well as removing the battery but still no luck. My next step would have been to remove ML and perform a re-install and see what that produces.

Peter

Hi Alex,
Yes, it was.

Having selected a Cropmark, and enabled the Histogram, Zebra, Focus Peak and the first three options under the Arrow/Set menu, I noticed that I was having to click more than once to change the (on screen) Arrow/Set functions. Five or ten minutes later I was unable to get them back after turning them off using the "AV" button. I rebooted and got them back but the same thing happened again. I then tried disabling all other functions and removing the battery but I cannot get them back on screen even though they are enabled.
   Perhaps my last post "Arrow/Set shortcuts" I made earlier on today are a part of the same problem. Any ideas anyone?

Hi everyone,
I really like the Arrow/Set shortcuts, but what does the "Use Set button: On/Off" do in this feature?

Their was a shortcut option in the Christmas edition to use the "Set" button or "1/2 a shutter button press" to begin recording. In v2.3 the "Set" button is not made available as a shortcut to begin to record in movie mode. Do I have a glitch, or has this been eliminated?
