Ok, I'm going to apologize for the threadjack, but I'll use the fact that I really don't see this thread as going anywhere useful as an excuse.

...I've never had so many brides ask what camera I use as I've had in the past few weeks. Its crazy!

And, personally, I find it kind of offensive to judge me by my equipment rather than my ability.


This was posted here a while back, seems relevant to your concerns:

Site Information / Re: Shallow depth of feild.......... HOW ??
« on: March 29, 2012, 08:16:01 PM »
What's with the "small aperture" business, people?  The OP needs a large aperture (small f-number) for thin DoF, but can't get it with flash because the shutter speed is limited to 1/200 s.

The solutions are correct, though - set the flash to high speed sync (HSS), or use an ND filter.  The problem with both is flash power.  HSS dramatically reduced flash output, and while ND filters block ambient light, enabling the wider aperture, they also block the flash output just as efficiently (obviously).  So, the bottom line is that with HSS or an ND filter you can get a shallow DoF in bright ambient light, but you'll be limited to just a little bit of fill light from the 580EX II.  If you want to actually overpower the sunlight, you need more flash power, especially if you want to soften that fill lighting with modifiers. So, many outdoor portrait shooters turn either to arrays of strobes (3-4 flashes in a softbox, usually Yongnuo/Nissin flashes and 'dumb' radio triggers to keep things affordable, and/or monolights with lithium battery packs for portability - that's the sort of power needed to overcome direct sun.

Ever wondered that it might actually be fun watching your high res pics on a high def television ?

Lol - sure, it would.  Break out that fancy Core i7 computer of yours and Google "1080p resolution".  Then open the calculator widget and multiply 1920 x 1080.  Do you honestly think there's a difference downsampling from 36 MP vs. 22 MP to view images on a 2 MP display.   ::)

The phrase, "Quit while you're behind," keeps popping into my head, for some reason.

Let me put it in another way.  If you're in for a new computer and you buy the latest core i7, nobody finds that strange. Everybody finds it normal that you buy the latest technology.  When you're in for a new camera and you want to buy a 36 Mp one, because that is the latest technology too, everybody on the Canon forums finds that strange.  Why is that ?  It is in the human nature to want the newest products at the latest technology.

So, you're suggesting the 5DIII is outdated technology?  Ouch.  On what do you base that assertion?  The D800 has a slower frame rate, and the 5DIII offers a 50% higher specification there.  What's outdated now?

Let's look further at your analogy.  Which is better - a Core i7 with a slower clock speed and an HDD, or a Core i5 with a faster clock speed, more RAM, and an SSD?  Different systems perform better in different applications, but for many needs the i5 in that configuration will perform better, 'outdated' or not.  Now...with a card full of 36 MP images to process, you're going to need that Core i7 and tons of RAM and the SSD...and you'll probably still need a pot to brew some tea while you wait...

Sticking to 22 Mp will cost them a lot of money.

It may cost them your money.  They're not getting my money for the 5DIII either, but that's only because 18 MP is plenty for me, so they're getting double the amount of my money for the 1D X.  But you and I are in the minority.  There are lots of people with a 5DII who really only need a better AF and they'll have the perfect camera - the 5DIII fits the bill.  There are even more people with a Canon APS-C body who didn't get a 5DII because of the AF, and the 5DIII fits that bill, too. Canon will be raking in money hand over fist from the 5DIII.  Oh, and just as a little bonus, they're going to keep selling the 5DII at its new lower price point for a while, and making significant profit from that, too.

It varies by manufacturer and by lens, just like for Canon.  But in general, quality is slightly lower, and quality control issues are slightly more common.

Yes, it's possible to use an adapter to mount a Nikon lens on a Canon body.  You lose AF and automatic aperture control, but AF confirmation is retained with a chipped adapter.  Note that the reverse isn't possible - you can't use a Canon lens on a Nikon body (and retain infinity focus, at any rate).

whether or not you can afford it is irrelevant.  people can still understand business models without tons of cash in their pockets.

True...but it can bias their viewpoint.  Consider an extreme example - the cost of Vertex Pharmaceuticals' Kalydeco, a treatment for cystic fibrosis.  I understand the business model which results in pricing of $300,000 for a year of drug, but if I had a child with CF I'd certainly be damn angry about it...

Fair enough but a child with cystic fibrosis NEEDS the medicine and are being gouged...

I agree with your point, but that's exactly the bias I was referring to...'gouged'.  A business model is a business model, and many factors go into setting a price point.  In this case, CF is a very small market, and the drug is only effective in 5% of patients in that already small market.  R&D costs are high, and spent, and must be recovered for ROI. 

Similarly, the cost to produce a 1D X is not double that to produce a 5DIII, but the cost to the consumer is double.  Or for an even more direct example, compare the D800 with the D800E - basically the same camera (in fact, they took something away rather than adding something to the -E version), but fewer expected sales means a $300 higher cost for the product.  Selling price has nothing to do with production costs, but rather is a combination of market forces and, to some extent, R&D recovery - that's why pills that cost literally pennies to produce can cost hundreds of dollars for the patient.

EOS Bodies / Re: 5D3 Mirror Lock up use and reccomendations
« on: March 29, 2012, 02:42:08 PM »
The major point - when you use live view, it's the same as mirror lockup.

Not exactly - it's better.  Live View uses an electronic first curtain, so not only do you get the reduction in vibration from MLU, you also get a small additional reduction in vibration from the first shutter curtain.

If you want to get the most detail from your images, then the major area of your image's histogram should be towards the right.


Thanks for pointing that out, I only discovered this fact after some try and error - maybe they should have put a  sentence like this in the manual :-p


The concept is termed ETTR.

EOS Bodies / 5D3 Mirror Lock up use and why it's easier on a D800
« on: March 29, 2012, 02:27:08 PM »
It's a shame MLU is buried within so many menus, forcing those that use it frequently to assign a C# setting to it

Nikon has a button for everything, and every button in its place...

See what I did?  I made this a 5DIII vs. D800 thread.     :P



Seriously, I don't mind it being 'buried'.  First off, one tip for that is to add it to My Menu then set My Menu to display first, that provides easy access.

But personally, I think a C# dedicated to tripod shots makes a lot of sense.  If you're going to enable MLU, you are probably shooting landscape, macro, still life, etc., as YellowJersey suggests.  Thus, you probably also want to use the self timer, ISO 100, etc.  So, I just assign all of those to C1.

Pardon me the silly question, but if Canon is so smart, why the first three best seller DSLR cameras on Amazon are Nikon's?

Last month, Canon held 4 of the 5 top spots, including #1.  It's unclear how Amazon ranks their sales (updated hourly doesn't mean the rankings reflect only the last hour's worth of sales), but it is clear that Canon has far more of the global dSLR market share than Nikon.

Lenses / Re: Canon 200-400/1.4x vs. 600/4 II
« on: March 29, 2012, 01:40:35 PM »
Tough choice.  I'd be inclined to the 600/4 II, I think, given that you already have the excellent 70-200 II for the closer part of the range.

...I added a security. I put an optech utility-loop : the rope side of the utility loop around the BlackRapid buckle and the BR carabiner through the loop of the utility loop. In that case, if the rivet wears off to a point that it can go through, the utility loop will prevent the carabiner and attached camera to hit the floor.

Great suggestion for an inexpensive bit of extra insurance - I think I'll duplicate that setup!
