OK. I still think the retail price of ff cameras is disproportionally high vs crop cameras but it's not as much as I thought. I am generally against spending a lot of money on camera bodies to begin with but the current prices on the 5diii and the1dx don't seem terribly out of line

i read the article. it is outdated (2006). i don't know if the same percentages apply now? the article concluded that you got 5 ff sensors vs 13 crop sensors from a "silicon wafer". that translated to a cost of $385 vs $38. this conclusion was based on knowledge of semiconductor production and conjecture. not known costs. i don't suppose there is any published information about what the actual manufacturing costs of various sensors are?

TexPhoto and candc: many thanks!  I have been awaiting reviews on this lenses.  Can you recommend any good technical reviews?  Except for The Digital Picture and slrgear reviews (I have read already) and I do not bother with dxo.

John

one of the admins here posted that they were in the process of a review, i don't know if it is still on or not? there is a fun one at petapixel. dxo rates the sigma as the best tele-zoom on the 5diii. many don't agree with the scores there but the measurements are useful to look at.

i am not a socialist and i believe in free enterprise but i don't agree with price gouging. i think the price of ff cameras has been artificially inflated for a long time. they are free to charge whatever they want as long as they are not involved in collusion and price fixing. afaik that would be illegal in the u.s.

Trust me, I'd love to have the FF prices as low as they can be. But do you honestly think that any manufacturer never tried to undercut the price to gain more market share? FF prices are falling over time and one day, they'll be as cheap as current entry bodies (fool's hope of mine), but I guess you are just upset about the pricing (as many others are). If there was a cartel deal between all FF manufacturers then either one of them would try to undercut the others to grab its market share or somebody would certailny whistleblew it a long time ago.

i have heard the argument about a ff camera costing more due to the sensor, mirror and other parts being bigger but that just doesn't seem rational when the 6d is as cheap as it is. i reckon ff sensors and parts cost a bit more but not enough to double the price. i would guess 20% more. take the 7dii 5diii comparison. they are the same size and the build is as good or better on the 7dii, it has gps and the dpaf sensor. it may well cost more to make a 7dii. i know about economy of scale but i can't see how the 5diii should cost twice as much.

Actually costs go up pretty dramatically as sensor size increases.
Every silicone platter is going to have defects on it, usually caused by dust in the air, and it costs the same to process the platter regardless of what you make out of it.
Just as an example, if every platter has an average of ten defects and you make 100 sensors out of it, you're probably going to lose 10% of your product. If you make ten sensors out of it you have the chance of getting nothing at all.
Basically that's the equation you face with sensors larger than Full Frame right now.
I remember reading that back when Canon was starting FF production they had to move their cleanliness standards to a whole new level.

ok, so how much does the sensor on the 6d cost compared to the one in the 7dii?

If you have evidence that such activities are occurring, you should report it to the Federal Trade Commission (www.ftc.gov).  But I'm guessing you just think they cost too much.  That's certainly your prerogative (of course, writing that they are engaged in price fixing is libel), just as it's Canon's to set prices to maximize their profit.

that's it, i am calling the ftc, fda, cdc, and every government agency in the phonebook! canon is spreading a disease called g.a.s to sell you the cure and then they are jacking up the price on top of it!

i really like the 7dii for the af, buffer, and speed but it does make me a bit irritated to think about how canon could put the 6d sensor in the 7dii body, sell it for  $1800...

Yeah, and I bet you're irritated that Chevy didn't put a Big Block V8 into the Camero instead of that piddly little 3.6L V6 and sell it for the price of a Cruze, too.  Because that would be just so feasible...   ::)

it is not like the analogy you are referring to which would be physically difficult and expensive to produce. the sensor in the 6d is not expensive and it would not be difficult to put it in a 7dii body.

 to me its greed. i don't mind paying a fair price for a product but i don't like getting ripped off.

Sorry, but you're being rather naïve.  A FF sensor is bigger...a lot bigger.  That means a bigger mirror assembly.  A bigger sensor means a bigger AF sensor, a bigger pentaprism, a bigger metering sensor, etc.  Oh, you still want 10 fps?  Ok, that's the 1D X's mirror assembly.  Willing to have a somewhat lower frame rate, say...6 fps?  That's the 5DIII.  But you want it for $1800? 

Me dear ol' dad, who hailed from the Emerald Isle (by way of Chicago) used to say, "Wish in one hand, sh!t in the other, and see which fills up fastest." 

Oh, and by the way what you call greed, Canon would call trying to generate the maximum value for shareholders – and that's their legal obligation as a publicly traded corporation.

I'd rather have the 7DII than the 6D sensor in the 7DII - by far.  One of my main reasons for wanting this camera is that I'm often left with 100% crops for my final image on my 20D (even at 400mm) and I want more pixels on the target.  The 6D sensor would leave me with fewer pixels, not more.

i like the 7dii as well. i guess there is the 5diii. the price on it is down around $2400 nowadays. that seems reasonable in comparison to the the 7dii i suppose. i think it was $3600 for a long time. i might get one now.

i am not being naive. i know exactly what canon is doing. not every company practices this way. mesa boogie is  a good example. they put out the best product they can make and sell it at a reasonable price. i don't agree with the business strategy of artificially inflating the price of a product just because they can. i understand it is their choice to do so but i don't have to agree with or defend that choice.

i have the 70d and 7dii, i agree that the iq is the same. i really like the 7dii for the af, buffer, and speed but it does make me a bit irritated to think about how canon could put the 6d sensor in the 7dii body, sell it for  $1800 and still make money. but no, if you want that you have to spend $6000 on the 1dx so they wont.

Is there any advantage to using this vs Lightroom?

its a good first step. it is fast opening and the quickview is good for culling and rating.

And now that Obama is going to warm up relations between the US and Cuba, more Americans can soon go there and enjoy their birds.


Lovely shots!

and more importantly we will be able to enjoy cuban cohibas without having to import them from switzerland.

great shots glenn, its nice to see you posting here and i look forward to more. your website is a great resource for bird photographers.

Looking at the crops compared to the tamron. They both look about the same at 400 f/5.6 the canon looks better in the corners at 560 than the tamron does at 600. If I didn't already have the tamron then I would get the canon.

those are really nice shots, the red squirrels we have here in the u.s. don't have those comical ears. they look more annoyed than suprised but they are still entertaining to shoot.
