Dave Lively commented on the blog post Big rumors from competition: Canon mirrorless with Four Thirds sized sensor? 1 week, 6 days ago · View
“they make enough money with DSLR and compacts” For a publicly held company there is no such thing as making enough money. Given a chance to make more they always will. Would you invest in a company that had decided it was making enough profit and was going to ignore opportunities to make more because [...]

Dave Lively commented on the blog post (FT5) Pictures of the White and Black GF5. Noise performance is on par with 7D. 2 months ago · View
Bigger pixels (compared to the G3/GX1) and an up to date sensor could be a part of any improvement in high ISO performance. But revised noise reduction in the JPEG engine will probably also play a role. Manufacturers seem to be hitting a wall in actual sensor performance with the gains in getting smaller each [...]

I am pretty sure it means 10.3. From a marketing perspective why go with a smaller number when a larger one is available? From an engineer’s perspective a 33% increase implies a linear scale which would be .3 stops. f-stops are logarithmic like the scale used for earthquakes. Going from a magnitude 6 earthquake to [...]

No, f stops are exponential.
A lens that lets in 700% more light (8x) is 3 stops faster, not 7.
But when you are talking about 33% the difference is so small it does not matter.

Stops are an exponential base 2 system.
So:
log(1.33)/log(2) = .41 stop
Not that much no matter what units you use. But I will take all the DR I can get.

+1 In addition to NDA there are also much fewer opportunities for the source of the sensor to get leaked. Most of the rumors seem to be either deliberate leaks or from press releases that are widely distributed before the camera is released. If Olympus wants to keep quiet the first does not apply and [...]

There is a market for quality kit lenses. Nikon makes a $650, 16-85mm, f3.5-5.6 zoom for its SLRs and sells quite a few of them. There is more to a lens than its f stop. Many people including myself will pay more for a lens that delivers better optical quality. The 12-50 has enough features [...]

I am not sure why you think this is the case. My D90 is not that fast and it offers fast and slow frame rates. It is a very easy feature to implement and is just another choice when selecting the shooting mode.

A popup flash might be hard to weather seal.
