EOS Bodies / Re: Patent: Dual Motor For Autofocus on STM Lenses
« on: September 14, 2014, 07:28:37 PM »
Olympus will introduce tomorrow the first lens with dual VCM for autofocus.

TWO IS BETTER THAN ONE
Smooth, rapid autofocus is a crucial factor in image quality. The 40-150mm f2.8 PRO’s innovative, industry-first Dual VCM (voice coil motor) AF delivers. Separating the focusing mechanism into two lens groups controlled by individual linear drive motors makes AF performance extremely fast and, with no gears involved, nearly friction-free and incredibly quiet.

Third Party Manufacturers / Sigma 150-600mm f5-6.3 DG OS HSM

Sigma went more higher end than Tamron with this focal length.  It has 4 additional lens elements (including 2 fluorite) and has larger diameter lens elements for the same aperture.  Build quality/features also seem to be a step up from the Tamron, although there is the penalty for weight (2.8kg vs 1.8kg for the Tamron).

PowerShot / Re: New Large Sensor PowerShot Rumor [CR2]

I wonder where they will source the sensor.  Panasonic is using Sony's sensor so Canon does have access to it.  They could also source it from Aptina or Sharp.

PowerShot / Re: Canon Announces the PowerShot SX520 HS & SX400 HS
« on: July 29, 2014, 11:01:42 AM »
The pricing for the SX520 seems over priced compared to the competition.  The Panasonic FZ70 has a 20-1200mm f2.8-f5.9 lens vs the SX520 with 24-1000mm f3.4-6.0.  The FZ70 also comes with an EVF and 1080p60 video, both of which are missing on the SX520.  The FZ70 came out at the same list price as the SX520 although you can get it for less than $300 now. 

Both of these models seem like they are too little and too late to market.  This doesn't bode well for the SX60.

The new 100-400 will get announced around the same time as the 7Dii.  And the 7Dii will get announced within a few months of the D9300.  Nothing to do but wait until the first shoe drops.

500mm would also give you slightly faster AF for BIF.

EOS Bodies / Re: Is Dual Pixel Tech Coming to the EOS 5D Mark III?
« on: February 28, 2014, 03:35:45 PM »
The "upgrade" for the C100/c300 included sending in the camera for calibration of the on-sensor PDAF.  This is more than just a firmware upgrade.  Canon is also charging $500 for this service.

Just remember that the Dual PDAF is not accurate and is only used for rough estimation of focus.  CDAF is still used to determine final focus.

PowerShot / Re: Updated PowerShot G1 X II Specs

I wonder why the 'Dual Pixel' AF sensor technology from the 70d is not getting shared with this and other Canon compact models?
