Remember which improvements the majority of 5DII users wanted? More megapixels and better low ISO performance weren’t high on that list. Better autofocus and higher fps were and that’s what we got. And even at + $500 compared to the high mp high dynamic range Nikon D800 they sell and probably outsell them.
Sales numbers, market share and profit, that’s what drives a company like Canon and there are no real indications that their current product range is hurting them in those areas so to them this is confirmation they made the right choices.
A new 5D next year? Don’t think so.
5D => 5DII 3 years;
5DII => 5DIII 3.5 years;
5DIII => 5DIV… 3 to 4 years probably.
So it will be well into 2015 and probably 2016 before we get a new 5D.
Agreed. I suspect we'll have a 5D IV announced late 2014, and delivered summer timeframe in 2015. Seems way too early to be getting the 5D III replacement.
I like Canon to take their time. As it has a positive effect on their next product tech wise. I won't be in the game for a 5DIV. The 5D3 still remains more camera than I ever can handle properly 8) So as improved high ISOs beyond 25k are my main interest, I will be glad to see the 5DIV's specs which will kinda forecast what the 5DV will be based on. 1/2 a stop to a full stop better high ISO by 2018 would be a tremendous leap for the 5DV. Till then I am well equipped. Still working on my first 10k frames with the 5D3.
Just out of curiosity, when you say half a stop to a stop better high ISO...what do you mean by that? I'm sure Canon could simply add a native ISO 51200 or even native ISO 102400, without really changing anything.
That said, physically, I think it is impossible for any camera to have a true two stops better performance than the current 5D III...not without significantly increasing pixel size, or increasing pixel size to some degree and maximizing Q.E. to nearly 100%. To achieve a literal reduction in noise by an actual full stop, one would need to either double the Q.E. (which would put it at 98%...so far, achieving Q.E. above 90% requires some significant and powerful cooling to keep the sensors at -80°C), or double the pixel area (which would require sensors with twice the pixel pitch, or four times the area...so pixels would jump from 6.25µm to 12.5µm...a megapixel count of about 5.5mp). Neither of these seem likely...the cooling isn't possible in a battery powered mobile package for Q.E. of over 90%, and the reduction in megapixel count to a mere 5.5mp would deter the majority of potential buyers (although I'm sure there are some low light fanatics who would absolutely LOVE to have a legitimate, low noise ISO 25600 and usable ISO 51200.)
Anyway...just curious what people mean, or think, when they ask for "two stops better high ISO performance". Are they just asking for two more stops of high ISO settings...or are they asking for two stops better noise performance at those higher ISO settings. The former is possible, the latter...probably not so much...not for a while for one stop better performance (we'll need either a radical breakthrough in circuit design and/or wafer materials...or incredibly efficient supercooling that fits into the area of a couple inches square), and two stops is probably impossible due to the physical nature of light and how it's handled by a sensor.
