EOS Bodies / Re: 5D3...why only usb 2.0?
« on: March 13, 2012, 07:07:11 AM »
i only need usb for tethered shooting.

i had great hopes that the 5D MK3 has gigabit ethernet.
in the end a gigabit ethernet chip costs next to nothing today.

usb 2 is a dissapointment.. i agree.

seems like on internet forums gather the whiners.
i mean.... 5D MK3 is on amazons top list for days... so the price seems to be no such big problem as some make it.


r u sure??

well you can see it yourself or not?
it is in the top 10 list or not.. so why do you ask?

Ok folks, when will the next 5D/1Dx come out? Maybe in 3 years, many more, are you all saying that the technology is that slow? the cameras that just got release are here to stay for a while.

imo sensor design is slowing down.
today they are doing finetuning.

microlenses, faster read speed all fine, but how much does quantum efficiency increase?
as r.n clark wrote not much

Complications regarding the perceived performance of pixels, pixel size and sensor size in digital cameras over the last decade (about 2000 to 2009) is a significant refinement in technology. While the quantum efficiency of sensors in digital cameras has not really changed much, other factors that have improved include: fill factor (the fraction of a pixel that is sensitive to light), higher transmission of the filters over the sensor, better micro lenses, lower read noise, and lower fixed pattern noise.

you can´t expect huge jumps in sensor design today... well you can but that would be unrealistic.
making the sensitiv area of the sensor bigger (backlight, exmor) was a nice step but we will hit a wall sooner or later.

I respectfully disagree with the OP.   Contrast-detect AF is not yet good enough to replace phase-detect AF and on that basis, and until there is a significant advancement, we are not approaching the end of the DSLR. 

well sensor based phase AF could replace the current phase AF in a few years.

right sony is making nikon sensors... and sony is making dslr cameras too... so how can that be good for nikon?

in the end they are competitors and nikon is dependent.

and canon is creating a huge amount of patents year after year... so you worrys are needless.

Why has the green more detail as the red ??

i think that´s no wonder.
it is because of the bayern pattern. it has 2x more green sensitiv photosites then blue and red.

In SOME parts of the scene, the 5D3 image looks as though more NR has been applied than in the D4 image, but ultimately, the 5D3 image does show more fine detail IMHO.

yep it´s the red parts that made me wonder.

otherwise it is ok ...i say...  :)

Different lighting, etc. , etc. can cause this.

don´t they keep lighting constant?
i mean... what sense would the test make if not?

yeah i wouldn't expect the Mark III to get anywhere close to the D4.  The D4 will be impossible to beat.  I doubt we'll even see the Mark III competing with the D3S.  Those camera's are low light beasts. 

well i have to admit the D4 examples look good.

you don´t have to go high as ISO 6400 even ISO 800 shows more details in the D4 pictures then in the 5D MK3 pictures.... at least in the reds... they are smeared into oblivion.

im really curious to see what the 1D X and D800 can achive.

having a phottix odin i rather buy 4x 580 EX II then two of the new flashes.

It's drama for me. There is nothing to compare with D800. I waited for 5D3, having a 5 lens from Canon, but now I decided to sell it and switch, unfortunately.


goodbye!

I am using the photozone data, BUT I am using the crop frame boarder (not extreme corner) resolution data and extrapolating it to the full frame data. This essentially mimics a 40 megapixel sensor at the half way point of the frame which is an extremely accurate way of measuring considering we're dealing with a 36 MP sensor. Most of Nikon's lenses are barley resolving two thirds the resolution at this point so it's safe to say that they wouldn't take advantage of 36 megapixels over the majority of the frame.

i would say post an example.
take the sweetspot of the lens and post your calculation.

i mean as engineer you know that people like to see hard numbers not just talk.   ;)

A long time ago I thought I remembered, reading or hearing, that 8MP was the goal or benchmark. That at 8MP this was the number that would be most analogous to film.

What IS the MP count- or is the question more complicated then this?

well i don´t know what is the truth.... but i read everything from 8 - 45 million pixel.

edit:  well there is one guy (but i don´t give him more credit then my dog on photographic things) that wrote the following:

Quote
Since the lie factor factor from digital cameras is about two, you'd need a digital camera of about 87 x 2 = 175 MP to see every last detail that makes onto film.

i don´t want to support the guy so i don´t give the source.. i think some here can guess.  ;)

EOS Bodies / Re: Canon 5D Mark III: Some perspectives/concerns
« on: March 04, 2012, 05:17:05 PM »

Being a big fan of Ken Rockwell and his website of "many things", I do agree with his perspective that camera bodies in general become obsolete the day they are released, much akin to driving a new car off the lot. Therefore, it is critical that enough people buy this new camera such that the support is maintained and resale value and demand stays high.

I also agree with his recommendation of pre-ordering ASAP, as there tends to be huge waiting lists, and potential fluctuations in prices down the road (boy.. I feel almost like I'm playing the stock market now!). I should note that the Amazon pre-orders for D800 dried up in pretty much a day.. not sure on the Mark III but most of the brick-and-mortar stores in Toronto have pre-orders available as of today and on their websites


there is one reason ken "beggar" rockwell is saying that... so that he makes money from the noobs who visit his website and go to amazon etc. from his links.

i would never preorder a 3000$ camera without reading some proper reviews about it or look at it first hand in a store.

i don´t need to be the first to have it.. i need to make a informed decision.

and i really would not mention ken rockwell when people shall take you serious!!
i don´t know a photographer with a worse reputation on the net.....
