Videography Technique / Re: Tascam DR-60D ON TOP of Camera
« on: September 07, 2014, 09:20:52 AM »
You always run the risk of busting the hot shoe.  Its a lot easier to do than most people realize.  The best configuration ive seen is to use a bottom plate and mount the device to the side of the camera.  I also tried mounting it to the bottom of the camera and and found it would introduce noise into the cameras audio when wanting to use that track to sync the PCM audio.  Its also difficult to sync the start and stop of both devices at the same time.

Still waiting for some smart engineer to develope a release that will start both recording at the same time.

Wow!  Really F6.3 being marketed as a sports lens?  Maybe on the planet Venus.  Rarely is F6.3 enough to stop sports action.

My thoughts are that it will have wifi if the rumor is correct that it can sync time between 7dii cameras.  Otherwise how could that be achieved and maintained?  Also many of the gps chips now are combined with wifi..or vice versa...so from a capability standpoint this would not require much additional tech other than firmware.

EOS Bodies / Re: Update on the EOS 7D Mark II Spec List
« on: August 23, 2014, 10:44:51 AM »
I really have a good chuckle at everyone ready to jump ship to Nikon over rumors and lack of innovation.  I for one just want a camera that works until I choose to upgrade and that is why I chose Canon.

I know many other professionals that have gone with Nikon and switched to Canon because their equipment had become unreliable and those failures cost them big $$$...and I'm not talking about the gear.

There is a cost to pushing the envelope constantly.  Canon strives to produce quality gear that wont fail when you need it most.  Sure occasionally there are issues, but I hear far less griping from the Canon pros than I do from the Nikon pros.  This is apparent due to Canon's lead in the market share.

Regardless of the sensor, the 7D2 will be a much improved model and from a reliability standpoint there is no comparison between Canon and Nikon.

I think what is important is when the pre-orders start ???

EOS Bodies / Re: Exmor vs DualISO

Nice work! Essentially, Magic Lantern is able to recover closer to the 'sensor DR' - by mitigating the effects of downstream read noise probably introduced en route to the off-imaging-chip ADC in Canon architectures.

The extra 0.8EV 'highlight headroom' (or sorts) is interesting. Makes me wonder if something similar is going on with the Nikon D810 & the 36MP sensor in there. DxO data suggest they're able to map a higher signal off the imaging chip to the same Raw value at ISO 64 -- essentially like extending the effective full-well capacity of pixels at this ISO.

I guess the concept is that lower ISOs give more detail (bits per stop) in the highlights and higher ISO's more bits per stop in the shadows (sacrificing highlights for more shadow detail).  Therefore it would seem correct that at ISO 64 you could extend the DR in the highlight end a bit more than Canon's ISO 100.  Your quality of signal would determine what you get in the shadows.

Dual ISO just uses the best of both ISO's beneficial range and leaves the overlapped ranges untouched.

That brings up an interesting point though.  Dual-ISO doesn't really yield lower resolution images.  Only the highlights and shadows are half resolution and it's difficult to notice that based on how our eyes work.  The rest of the image where the high and low ISO overlaps is essentially untouched and full resolution of your primary ISO.  The wider the difference in ISO, the less overlap and therefore more potential to have your image de-res'd.

If you are shooting in daylight and want to recover shadows, use a high ISO of say 800 and a recovery ISO of 100.  If you are shooting in low light and want to play around with HDR in that realm, you should increase your recovery ISO.  I haven't tried low light HDR but it seems conceivable you could get better results than without Dual-ISO.  Say using ISO 6400 and a recovery ISO of 800 or 1600.  I'll have to play with that and see if there are any real benefits.

Very nice article, lots of effort to do that, most appreciated

Can these results be extrapolated to a 7D? I don't mean would a 7D be the same as these examples but would it have a similar ratio of improvement?

If so and this is all software based, makes me wonder when the (20.2MP guess) 7D2 makes an appearance and shows a similar improvement we will all be shouting praise be!!! and all 7D owners clamoring for an official software update  ;D

Well if there is a marked improvement it will be easy enough to test how it was/wasn't done, just find a tree  ;D

Dual-ISO works on every camera that ML supports (nightly builds only) including the 7D.  However just note that you cannot push the ISO on the 7D much more than 800, even with Dual-ISO, or it really starts to fall apart.

I even use Dual ISO on my EOS-M!!!

Really surprised this topic hasn't generated more interest.

Doesn't this show in real world terms just how easy, without changing any sensor tech, it would be for Canon to improve one of the most complained about aspects of their current sensor design?

What makes you think they haven't used this in the 1DX?  ;)

I've been using ML for quite a while now and use Dual ISO more than I really care to admit.  However there is another round of tests you need to do.  That is to use ISO 100 as your secondary or recovery ISO and 800 or 3200 as your primary.

Theoretically the results should be similar but there are reports of differences.  I assume that it has to do with the number of bits recorded in the lighter part of the DR and less so in the shadows.

I started out using Dual-ISO with a high recovery ISO and discovered that I could not get the shutter speeds I needed for sports or even birds in flight.  So I switched to shooting at ISO 800-1600 and recovering to ISO 100.

EOS Bodies / Re: 5D3 No Longer in Production
« on: August 17, 2014, 10:59:45 AM »
Best Buy 'discontinued' the 5DII at least three times before the 5DIII was announced (and Canon didn't discontinue the 5DII until well after the launch of the 5DIII).

So I'd say this means nothing.

Yes i think what it indicates is "chest guy" is discontinuing it because of poor sales.  They will order one if a customer wants it.

I can't imagine Canon doesn't read to some degree forums like this  one especially. If they don't then shame on them. The people here are the 80/20 rule. The 20% of their market that comprises 80% of the base avid user. I would like to believe that Canon is wise enough to know how to produce a camera properly for the given target market. With a 2000-2500 body, they should darn sure know what the criteria are. And I believe folks like me and jrista are a big chuck of that market. Give the pros a reason to keep those white lenses on the sidelines of Saints games and whatnot. If Canon gets too over zealous with pop culture features, the artists out there will continue their outward migration. 

The 5D3 was a killer piece. I expect the 7DX to keep within that pattern and deliver strong fundamentals that will be a harbinger of the next gen FF pro bodies. They need a Sony/Nikon wrecker. If there is any wisdom left at Canon, that's precisely what they plan to deliver through 2015

A sony/nikon killer?  Canon already has the market share.  No, what they need is a 7D replacement in between the 5d3 and 1dx that will fulfill the gap lost when the 1Div was discontinued.  No matter what the 7dx has spec wise you can be certain it will be much better than the old 7d.  How much better we will have to wait and see.

Canon already has enough consumer cameras and marketing this to appeal to consumers would just be bad marketing.

I really don't see the benefits of adding a touch screen. I prefer the tactile feedback from a button or a dial. Would a touch screen still work flawlessly on a cold winter day when it's snowing and the gloves are on? Would it work if I was out shooting in the rain?

if you were out shooting in the rain th touch screen would be the first to die.

No wifi or touch screen? Bummer. All future canon prosumer cameras should have BOTH wifi and touch screens IMHO.

I never liked Canon's wifi implementation.  I have had great success using an Eye-Fi card when I need that capability.  I dont think that built in wifi would be a deal breaker since it can be added later.

Touch screens are very gimmickee on a camera.  I've tried to get used to it on the M and while I can see that it makes sense for some things, I find it cumbersome to change settings and need to take my eye's off the subject and dink around with the camera.  I prefer to change most of the important settings by feel or program the common ones into custom modes.

I would rather see them put the R&D dollars into better IQ and better AF capability than consumer features like touch screens and wifi that runs the battery down even faster.

EOS-1 style top plate

No mode dial?
Darn it! You beat me to it! ;)

You cant get EOS1 style weather sealing with a mode dial.  All buttons underneath a continuous rubber film will seal it from rain and gorilla pee.  More to sway my decision toward this being closer to a 1DX than a 7D and hence a loftier price tag.
