16-35L lens back from Canon repair

by AndrewCCM on Mar.12, 2009, under Personal Opinions, Photography Equipment, Sports, Video

Looks like a brand new lens! I did a few tests around the house and it looks to be working very well. Time will tell I suppose.

Just wanted to give a shout out to Canon in Irvine, CA. You guys did a great job yet again. Much appreciated.

Next goes my 1D3 recall for AF calibration again. I requested it go to Irvine, but was told it had to go to the Newport News, VA site. In the past, they have not done such a spectacular job with my 1D3 and I had to end up sending to Irvine to fix their mistakes.

However, I have been reading very positive remarks about the VA fix on this latest round of recalls. So I will keep my fingers crossed.

I have a NHL game to shoot tonight and then off it goes via UPS. I don’t have another sporting event to cover for a week or so. Hoping that CPS membership gets the fix done quickly and back to me.

Anyway….as of right now, I am a happy camper. I’ll give the 16-35 a good workout tonight. HOPEFULLY, I don’t get another puck into it. LOL

Considering the glass wasn’t damaged, it doesn’t look too bad.

Knew this would happen eventually.

by AndrewCCM on Feb.24, 2009, under Photography Equipment, Random Stuff, Sports, Video

Well…after shooting close to 30 NHL games, I finally got my taste of what it feels like to be hit by the puck. Unfortunately, it was my lens that was hit…not me. I think I would have preferred me.

I just happened to be testing the Canon 16-35L (notice how wide the shot is) in video mode on my 5D Mark II. The action was at the other end of the ice and BAM! out of nowhere, they send a puck the length of the ice right into my lens….

Hopefully it can be fixed without an exorbitant amount of cost. Just glad it didn’t hit the lens glass. It’s mainly all structural housing damage (that I can tell)… Can’t zoom in or out and the MF ring is tighter than heck. I’ll post a pic of the damage later…but for now… here is a little video clip of my test (albeit just a minute or 2) and impact. You can click full screen mode if you’d like to see it in 720P HD.

5D2 Video Exposure Lock Revelation

by AndrewCCM on Dec.23, 2008, under Personal Opinions, Photography Equipment, Video

Just a quick note on something that has been driving me crazy. If you happen to use C Fn. IV-1 set to 3 (as I do)…you cannot lock your exposure prior to starting recording. I have spent a few evenings trying to figure out why I couldn’t. That would be why. I switched it over to 2 which gives me sort of a workaround. (I don’t like my shutter button to focus which it does by default – 0).

I also just added that C.Fn to My Menu so I can easily change it when shooting video versus stills.

Still learning and posting.. LOL

5D2 1080p Video – EDITING

by AndrewCCM on Dec.22, 2008, under Personal Opinions, Photography Equipment, Video

Just a quick comment on those considering shooting this new camera for video and subsequently editing.

At this point in time, if you have an Intel based MAC you should be in good shape. PC’s on the other hand, seem to be having significant difficulty processing the h.264 content. I am being told that this is due to Apple’s lack of feature set within it’s Windows Quicktime application. I have been working on trying to find a decent PC-based NLE workflow with the footage and have pretty much failed. Premiere Pro CS4 was my best hope and while it will edit and convert the content, it is VERY CHOPPY on the timeline while scrubbing. My PC NLE is 2.4Ghz Core2Duo, 8GB RAM, Nvidia 8600GTS, and XP-64bit.

The same footage brought into my Macbook Pro (2.4Ghz Core2Duo, 2GB RAM) works flawlessly within both iMovie and Final Cut Pro. I tried it on my wife’s iMAC with very similar specs and it worked well.

I believe that Quicktime on the Apple platform is able to use advanced GPU functionality and most definitely deals with the h.264 CODEC much better.

I’ll be keeping an eye out for a PC solution and report back.

That’s it for now. Have a very Merry Christmas!

Video Exposure Tricks

by AndrewCCM on Dec.15, 2008, under Personal Opinions, Photography Equipment, Video

Something I was playing around with…This may or may not help anyone, but thought I’d post.

As everyone is starting to realize, exposure control (or lack there of) with the video feature on the 5DMkII can be problematic.  In particular, with depth of field.   For instance, outdoors in bright light the camera will automatically stomp down the aperture to very small f-stops.. Well let’s say you want to have a shallow depth of field outside… The only solution that I was able to figure out was to stack ND (Neutral Density) filters to force the camera to open up.

Well..  Here is something interesting (at least to me).  The order in which the camera seems to determine exposure is…  1st set the Aperture, 2nd Shutter, and 3rd ISO.  When it needs to make adjustments after the initial exposure, it reverses the order.

So here’s the trick.  Cover your lens with your hand and lock your exposure… This will more than likely make your exposure the shallowest FStop available, crank up the ISO and lower the shutter speed.   Well as long as you have your exposure locked everything will remain like that even when you point it at your subject outside.  From this point, you can then press the * button and it will start readjusting the exposure for the current scene… BUT IN REVERSE ORDER!

So.. Basically, it will drop your ISO levels dramatically, start raising your shutter speed until it gets the correct exposure.  YOUR APERTURE WILL NOT CHANGE unless it cannot compensate with ISO and shutter for the conditions.  I have found that in most situations this is not a problem.  So to sum up… you have tricked the camera into opening the aperture and make other adjustments for the exposure.  Kludgy…but it works.   I would guess you could come up with various ways to have it set various apertures by toying around with the amount of light in the initial exposure.

One thing I haven’t tested is just the opposite.  For instance, in a dark indoor scene where you need more DOF, you might point it at a lamp or shine a flashlight into the lens to make it stomp down.  Then use the same trick to make other adjustments.

Anyway..  Just thought this was interesting enough to pass along.

Have a good afternoon.

5D Mark II – Video clip with Hands On demonstration

by AndrewCCM on Dec.04, 2008, under Personal Opinions, Photography Equipment, Video

Here is a video clip that I made basically demonstrating what I wrote about in the blog below.  It by no means is a demo for video quality sake…More so to show how the exposure works with it’s shortcomings.

I don’t currently have a PLUS account over at VIMEO, so you’ll have to visit this link rather than me embedding it.  Sorry about that.

5D Mark II Video – Initial Observations (1st draft)

by AndrewCCM on Dec.04, 2008, under Personal Opinions, Photography Equipment, Video

I just tested the video mode for about 2 hrs tonight and It seems to work very well (albeit, with some significant drawbacks).
THE GOOD:
First and foremost:  IQ – IMAGE QUALITY.  The resulting IQ of the 1080P HD video is stunning and very noise free.  The ability to use an extremely clean full 35mm sensor and high quality lenses will undoubtedly give the short film maker the ability to create media that has a distinct motion picture feel and will appear much different than the typical “video” look of normal HD camcorders.
IS – IMAGE STABILIZATION:
When using an IS lens (and enabled on the lens) it does work and VERY WELL. You do get motor noise in the mic (which is right below the [5D] label, but the resulting shake is dramatically improved.
File Format:
Canon chose to go with a very high bitrate and efficient CODEC H.264 with its video files.   It’s bit rates are higher than most commercially available Blu-Ray titles that are currently available (from what I understand).  And the files, while large, are easily edited in your favorite NLE (Final Cut Pro, iMovie, etc…)
THE NOT SO GOOD:
AUDIO:
The audio recorded via onboard mic is mono, but the line in is stereo and IMHO any serious audio should be recorded separately by an audio engineer or in worst case via a shotgun mic or wireless fed through the line-in.   Another drawback is the fact that you cannot monitor the audio as there is no headphone jack and no manual audio gain controls.  Canon includes an AGC circuit which prevents overload, but can also give undesirable pumping of gain.  Audio is recorded at 44.1kHz 16bit.
EXPOSURE:
Ok, here is the skinny concerning manually setting exposure (at least from everything I can figure out).  My hands-on observation is contradictory to the widely publicized Vincent Lafort Blog.

Specifically, you can NOT manually set your aperture/Shutter/ISO for video.. You can set it for still capture during video mode, but it doesn’t translate to the video recording.

You can, however, use the * exposure lock to set exposure so that it does not ride up and down when something bright enters the frame, etc… This is very useful.

Something that concerns me a bit (at least until I learn differently)…When shooting in normal indoor light (well.. tungsten lamp light indoors – What I would consider medium low light), the camera will automatically drop to the widest aperture and drop shutter speeds to 1/30th – 1/60th and crank up the ISO. While this is fine for video viewing and still looks very nice, it does wreak havoc with DOF.

In other words, if you are shooting in lower light, it is going to use the shallowest F stop and you cannot override that. You can manually change the EV, but that doesn’t necessarily change your aperture (just forces the camera to readjust it’s AUTO combination of settings)
Another example:
Now.. let’s say your shooting outside in bright light… (I haven’t tested, but I did point it directly at my lamp)… Your F stop will increase (lets say F8).. Well suppose you want to shoot a scene with shallow DOF like F2.8 and rack focus between subjects? As far as I can tell, you can’t…because you cannot override the AUTO Aperture.   You can use Neutral Density filters in bright light to compensate which may be a viable workaround for that environment…But that does not help low light shooting situations where you want to increase DOF.
INITIAL OVERALL SUMMARY:
So to sum up.. The video looks top notch and while it automatically controls exposure very well, the manual control over such settings is very lacking.  I am guessing when shooting short film or setting up for particular scenes, you will have to light it carefully and use a lens which max aperture is the max you desire (ie, if you want a deeper DOF, you might put a F4 lens on…and light it accordingly. Otherwise, if you have a fast prime..let’s say 35 F1.4…and shooting indoors…My guess is that it will bump itself to F1.4 (need to verify that) until you pump up enough light. The camera itself will decide when the light is bright enough to raise F Stop and/or shutter. I figure the same scene with a F4 lens at 1/60th.. would likely register F2.8 1/125 with a F2.8 lens…The results will be a shallow DOF that you may not desire (then again you might). It just seems to me that slower lenses might actually be helpful in some situations where you want to “trick” the camera OR.. in bright situations where you want the opposite, use ND Filters to force wider F-Stops in stronger light.

I realize this is the first generation of such a feature and it will only get better.   The 5D Mark II produces a beautiful video image, but the lack of control could be a killer for certain types of shooting. Perhaps they will give us a firmware update that will allow AV/TV control…But I am not holding my breath.

Anyway.. these are just a few comments after a couple of hours testing with my new body. I haven’t tried to edit anything and need to update my software a bit in order to process for the web… (these MOV files are HUGE) so I don’t have anything to post yet.

And for anyone that is thinking…”Show me a still image, it is afterall an SLR”.. I will in time. I just wanted to specifically address some questions that have been fuzzy about the video capabilities.

Take care,
Andrew
