Lighting / Re: Phottix Odin: Inaccuate high-ISO metering problem
« on: October 26, 2012, 10:25:48 AM »
Remember that when using flash in Av mode, the camera sets teh shutter speed to properly expose the BACKGROUND.  I believe it assumes there is little to no impact of the flash on the background.  That means in addition to changing the flash power, it is also adjusting the shutter speed to compensate for your ISO changes.  I don't have software on this computer that can read the exif, but check your shutter speeds.  It may be a case that the scene has fooled the metering calculation, and some of the extra light is due to too much ambient being added to the flash exposure by a slower than appropriate shutter. 

I, personally, have never had as much luck with ETTL in Av or Tv mode as I have in manual.  In manual, the camera can only control one vairable, and it seems to have a much easier time doing that.  I set the aperture for DOF, shutter to either kill ambient or balance the flash with ambient, and the camera takes care of the flash power to expose the target.

Lenses / Re: Guesses on lenses for Photoplus

Maybe price and availability of the Samyang 24mm TSE?  That would be cool.

I bought the 135L in May when it was on rebate, figuring the new one would be 2x the cost....may be years before I find out if I was right!  Honestly love it the way it is.  One of my favorite lenses.

An alternate view could also be that, given what Canon has pulled out of a 0.5µm process, it bodes well for what Canon can do with a 0.18µm process. 

No.  Sorry.  The only allowable alternative view on the internet is 'sell all your gear and switch to Nikon'.  Actual sensor performance in the real world need not apply.  :)

Seriously though, this is a good point.  You see it with computer processors all the time.  The new, smaller achitecture comes out, but for a time there is the older, larger achritecture in the market place with it.  And the real world performance is very small, if noticeable (in processors, its ususally power efficiency that is the major difference, not speed). 

Canon's latest sensors have been of very high quality, and have upped the bar on high ISO performance compared to previous generations.  Has the cow been milked for the last time?  I dont know, and neither does anyone but the Canon engineers.  The technology will reach a limit, and they will have to go to the next genearation, eventually.  We've been conditioned to think that something that was 'state of the art' in technology a few years ago MUST be obsoloete by now (whenever 'now' is).  But that is not always the case.  There are many layers that go in to performance of systems like this, and just because one layer has not changed in its base architecture doesn't mean advancements havent been made in the execution of that architecture, or that advancements in other areas of the system have unlocked more performance from system as a whole.

Lenses / Re: Lens combos under $1000

How about a used 24-105, and one of the Samyang 14mm lenses for the missing wide side?  I think you could do that for $1k used.

I'm a bit shocked about the missing red AF points in AI servo...would have thought the AF part of the upgrade would be identical to that of the 1Dx.  OR that we'd have gotten the red points, but not F/8 AF since that's been a 1D series feature exclusively to this point. 

Also wonder why they'd announce this 6 months before it was availabile....not like its killing me not to have it.  Just seems really strange to announce something so far in advance.  The 1Dx and 7D firmwares were available almost the same day, right?

Lenses / Re: IQ of 24-105 and 700-300 lenses
« on: October 23, 2012, 08:29:39 AM »
The 24-105, IMO, is one of those lenses that gets a bad rep just because so much stuff is repeated second hand on the internet.  The 'distortion' everyone talks about is there, but in most cases hardly noticeable and even then easily correctable with the excellent lens profiles availble in DPP and the Adobe products.  'Sharpness' is subjective, as what is sharp enough for one may not be for another.  Pixel peepers are often disappointed with gear that others are making excellent large quality prints with, so I tend to consider that fact when discussing sharpness.

I 'upgraded' to the 24-105 recenty from a 28-70 F2.8.  My old lens is in need of repair and I'm looking for a shop that still has parts.  In the mean time, i did not want to pay the current prices for a 24-70 F2.8 because they were in high demand and expensive even used.  The V II is way out of my range. 

I thought at the time i would be 'settling' for the slower lens, but it only took about 5 minutes after I put it on the camera to ask myself how I lived without the 24-105 for so long!  It is lighter and more versatile than the 2.8 lenses in the standard zoom range, and i find the IQ to be very similar.  With the newer bodies having higher ISO performance, I hardly if ever miss the extra stop of light.  Though, of course you can't recreate the F2.8 depth of field with an F4 lens at any ISO :)

In summary, the 24-105 is an excellent lens, particularly considering is versatility and weight.

EOS Bodies / Re: Trading 7D for 1D4 with high shutter count
« on: October 19, 2012, 11:50:15 AM »
If the money is not an issue...I'd do it.  Both camreas are roughly 1/3 of the way through their average expected shutter life.  (125k on the 7D, and 300k on the 1D series, IIRC).

EOS Bodies / Re: Red AF in AI-Servo fixed in 1D-X before 5D Mk III
« on: October 18, 2012, 08:52:14 AM »
I know it shouldn't by now, but it always surprises me when people take this stuff personally....

Its been pretty good to see some features being added via firmware to the 7D and now 1DX.  I'm sure we'll get something for the 5DIII eventually.  In the mean time I'll just have to resign myself to thoroughly enjoying the most versatile camera I have ever owned.  Darn those Canon b@stards. :)

EOS Bodies - For Stills / Re: Thoughts on the New EOS-1D X Firmware 1.1.1
« on: October 18, 2012, 08:36:16 AM »
In one of the original articles, its said there were three modes to chosese from: Brighter, Normal, Non-Illuminated.  I don't have a 1DX :( so I don't know for sure, but it appears the answer to your question is YES.

Lenses / Re: "Zoom Creep" on the 24-105L : My Solution
« on: October 17, 2012, 12:45:12 PM »
I bought a used one that creeps.  Kind of annoying but really not that big a deal.  I figure it could be refurbed if necessary.

I'll add my vote that we need the same for the 5DIII.  Though F8 AF has always been a point of differentiation on the pro bodies, I would at least like the red AF points. 

I wonder how many folks jumped to Nikon over the F8 AF issue, and now wish they hadn't?

I also prefer the twilight feel of the first (original) picture. 

The digital conundrum...because it can be changed, does that mean it SHOULD be changed?

<Dons disgruntled spec sheet fanboy costume>

What?  Canon can't get the 200-400 F4 L 1.4tc lens to market after more than a year of talking about it and now Sigma has a 200-500 AND its F2.8 ?!?!?!?!?   Canon is so out of touch.  How can they do this to us?  They must think we are dogs and will just eat anything they feed us.  No worse, they think we're dog FOOD!

I'm burning all my gear and switching brands.

<Doffs disgruntled spec sheet fanboy costume>

On a serious note...that thing is a beast.  I wonder how it would work as a telescope.  That would work out to a 7" F2.8 refractor....

5D MK III Sample Images / Re: Ultra long daytime exposures - 5D mkiii
« on: October 12, 2012, 06:54:07 PM »
I'm such a ND noob. With a 9 stop ND400x in daylight shooting landscape at infinity (something I might be shooting at f/16 with no filter) do I just factor the shutter speed by 9 stops and leave the aperture alone?
y


Yep.  You have to get9 stops somewhere to get the equivalent exposure.  You can do long exposures like those here, or use it to get shallow dof (wide apertures) in bright sun.

Third Party Manufacturers / Re: Considering switching to Nikon
« on: October 12, 2012, 02:46:42 PM »
If DR is your primary concern, go Nikon.  If you are going to stay with Canon and get a 5DIII, I doubt you'll find a more versatile body in existance.  I can't really say my composition, creativity, etc are better with the MKIII (just like they wouldn't be better if I got a D800), but I can say that there are a whole bunch of shots I couldn't get on my older bodies that I can get on the new one because of its low light ability, and that between the focus system and higher frame rate than older FF bodies, this one camera easily does the job of my two older ones (5d and 40D). 

Spec sheets are deceiving.  Its easy to make the grass look greener on paper.  My guess is a lot of people who switch systems either way will find, after all their horse trading, that the end result isn't that much different.  There are a few people who do so with good reason and really take advantage of the true differences in the system (like maybe tilt-shift availability, supertelephoto availablity for canon, or the few people who really NEED the extra DR of Nikon).  And there are a few people who will do so and pull up every shadow 4 stops just because they can, and be happy.  The rest...will be just where they were when they started.
