Large pixels generally have high read-noise which means they tend to have a tough time in such environments.  Read the text.  They claim to have developed technologies that counteract that affect (that read noise increases with pixel size).
Hmm, ok. But in the general discussion, noise increases when pixels get smaller (at Hi-ISO). It would be kind of obvious to think that noise decreases when pixels get larger (at Hi-ISO).

(maybe those are two different sources of noise I am talking about?)

7.5, not 7.2^2.
Yeah, my bad. :) But I think the principle is the same...2.4MP on FF would have lower HI-ISO noise than 18MP...I guess... :D

So if I get this right, Canon is taking a full frame sensor, and ENLARGING the pixels on it 7.5 times, and then market it as the best ISO performer on the market? DUH!

So the pixel count will be 18MP / 7.5^2 = 0,3 MP on a FF?

Ehm, I might have completely misunderstood, but how is this technical progress?

Lenses / Re: Keep or sell??

Hehe, lot's of advice in both directions. As expected. My thinking is: can you find another use for it, if it is not used on your main camera? Like someone said, macro could be one use, use on a backup/travel/throwaway body could be another, and testing out with adapters for MFT/Nikon/Sony etc. could be a third.

If you can NOT think of another use for it, and you KNOW it will not be used, give it as a present to someone you like with a Canon body. It will help their photography a lot. Saves you the hassle of selling it too... :)

Lenses / Re: Cheap Canon 300mm or 400mm
« on: March 01, 2013, 04:59:59 AM »
I hope Sigma or Canon will make a new lens category at some point.  Such as an f/3.5 300, an f/5 400, or a zoom with limited range but fast aperture, such as a 250-450 f/5, or 200-350 f/4.5...all of which with stabilization.  It's kind of annoying that telephoto lenses go from the $1500 range, to the $3500-$13,000 range...with nothing in between.

I am thinking Tamron might step up here. They now have VC and USD capable enough for this area. A good way to differentiate themselves from Sigma/Canon would be to provide some new combinations of fast primes, like 250mm f/2.5, 350mm f/3.5, and 450mm f/4.5... They would probably end up in the space 2-5k$ (keeping my fingers crossed) :)

I think the March announcement indeed is the 70D. I also think it will be the first camera with Canons new 180 nm process at around 24 mp and single Digic 5 for modest FPS. Wifi and GPS is a given, especially if it is 60D build. I think it will get a variant of 6D AF also for good low light photos and video.

I think 7D2 will also have a new sensor with same 180 nm process, but stay at 18 mp to be the FPS/Hi-ISO monster we all want. Basically a crop 1DX.

The reason for this is for Canon to put out the new sensor in a lower prestige body to get feedback for final spec of 7D2 before they announce it. It also gives the 7D2 a longer time as "latest and greatest crop body", as if the higher mp XXD is release after, it would pull down 7D2 prices. But if released before, the 7D2 lower mp can be marketed as "better", and as a consequence, will not be as sensitive for the next XXD upgrade, as that will certainly have even higher mp count. :)

PowerShot / Re: For DH, need recommendations

Check this one out:
http://www.getolympus.com/us/en/digitalcameras/tough/tg-2-ihs.html

Not easy to destroy. Small and perfect for biking. Fast 2.0 lens. Macro mode for flowers. Taking photos and filming in rain, snow, under water, you name it!

And yes, it films in 1080p. Under water.

PowerShot / Re: P&S - Faster lens or bigger sensor?
« on: February 28, 2013, 12:53:27 PM »
Well, compared to your average P&S, they ARE more complex. I do not mind it, but there are people who do. And among these people are notably my wife and all my friends's wives (told you I was biased). :)
My wife actually prefer automode on our DSLR, as she hates lag and poor AF.

PowerShot / Re: P&S - Faster lens or bigger sensor?
« on: February 28, 2013, 12:05:06 PM »
The answer is: fast and accurate Autofocus, that is sensitive and do not hunt in bad light.
For a P&S, this will be the thing making or breaking the pictures.

Back to topic, a bigger sensor (by 2x), equals a stop faster lens. All things equal (noise processing etc.) it should always be able to have a stop higher ISO with same noise, thus enabling same short shutter speeds as the brighter lens. But it will always have more flexibility at base ISO.

In reality, this scenario is very rare, so go with whatever feels right. There are more things to a camera. Color output, flash, handling/ergonomics and so on...

But my (admittedly biased) view of wives in general, they value responsiveness, simplicity and end IQ. So, G1X with large sensor, but complicated controls and slow AF would maybe not be a good buy, even if it has a large sensor and good IQ. :)

EOS Bodies / Re: New DSLR at the End of March [CR2]
« on: February 28, 2013, 10:12:24 AM »
Oh, if this is back to 50D with AFMA and metal body, I might choose this one over a 7D (depends on AF really). Hope it is available shortly after announced, so we don't have to wait until summer to get it.

Not sure if you have seen it or used it, but sigma has a 28mm/1.8 for FF too. One could try THAT one with NEX and Metabones to get a 28mm/1.3 lens equivalent? Metabones claims they are compatible with Sigmas for EF.

Lens is 449$ and Speed Boster is 600$, so still cheaper than Zeiss.

Unfortunatly, no long glass is available yet for micro 4/3 :(

Actually, this is not true. Both Olympus and Panasonic have telephoto zooms for MFT. 75-300 and 100-300 respectively. Granted, they are not very bright, nor L class optics, but they DO exist.

No need to be sorry for loving 28mm. (unless you mean sorry that the 1.4 does not exist) :)
It is all up to your shooting style.

If you are shooting crop, then Sigma is there for , as already mentioned.
But for FF, I guess you have to put your hopes to Tamron, that have said they will go for fast primes next.
If you have a NEX, you could try the EF50/1.8 or EF28/2.8 with Metabones adapter?
