EOS Bodies / 46mp sensor useless for landscape?

« on: October 07, 2012, 01:22:28 AM »

In most landscape situations, aperture needs to be set less than f/8 for large DOF. But according to the article below, 19mp is the max a 35mm full frame sensor can capture for red light (wav length of 0.0007mm) at f/8, doesn't matter if your camera has 36 or 46mp sensor...

So, what happens when a landscape picture is captured by 46 mp 35mm sensor at f/11? Do we see more blue than green and red? turquoise color shifted?

EOS Bodies / Price : Canon 5D Mark III + 24-70 II == Nikon D600 + 24-70 + 14-24

« on: September 13, 2012, 01:25:39 AM »

Price is based from Amazon:
Canon 5D Mark III + 24-70 II --> $3500+$2300 = $5800
Nikon D600 + 24-70 + 14-24 --> $2100 + $1900 + $2000 = $6000

Maybe it's time to switch to Nikon or Sony, unless canon can react fast. They are lossing the price war to Nikon and Sony(A99), plus their sensor is not as good as Sony's which are used by some of the Nikon models...

I guess Canon is focusing more on the video camera than still camera...

BTW, I just cancel my pre-order for EOS-M and ordered Sony Nex 6, the CMOS sensor (image quality) used in EOS M is not as good as Sony's previous generation Nex 5N.

Video

The Nikon D600 can capture Full HD (1080p; 1,920 x 1,080 pixel) video at either 24, 25 or 30 frames per. For 720p (1,280 x 720 pixel) video, a rate of 60 frames per second is possible. Video can either be shot using data from pixels across the entire width of the image sensor in FX mode, or with a 1.5x (DX-format) focal length crop, taking data from the center of the imager, without affecting the video resolution.

Videos are recorded using H.264 / MPEG-4 AVC format compression, maximum clip length is 29 minutes, 59. Even more unusually, it's possible to have the live feed piped to the D600's HDMI port as an uncompressed full HD signal, allowing it to be recorded using an external device and/or routed to an external monitor. If desired, this signal can be mirrored on the camera's own LCD display at the same time; the off-camera feed doesn't have any overlays added, so as not to impact external recording devices.

And the time-lapse photography function can be used to automatically photograph relatively slow moving action

PowerShot Cameras / Alert: Don't buy early production S100

« on: December 09, 2011, 12:03:19 AM »

Dpreview can't complete S100 review: "we've used three S100s, and the delay has been caused by concerns over optical issues displayed by the cameras that we've seen.", "...third sample that I have looked at, and the third with what appears to be a slightly decentered lens. Quality control issues can affect cameras from early production batches"

Rumors about the Nikon D900 · D800 web
The board of dpreview, and has so far appeared in the Nikon D900 and D800 rumors of another source.
· New Rumor: D900 + D800 Coming Soon

This rumor is a French magazine "chasseur d'images" comes from. This is a very serious and well-known magazine, every article about the new product was the fact.
D900
- 36 million pixels to ensure
- Low-pass filter less
- Video is 1080p 60fps, 720p 120fps
- Built-in flash is not
- Price is $ 4,000 or more
D800
- 18 million pixels
- 1080p 30fps, 720p 60fps
- Price is around 2500 U.S. dollars to 2800 U.S. dollars
Credibility because the rumor posted on the bulletin board is unknown, and the fact that the contents of this rumor Suppose unit full-size Nikon is likely to line up an ideal that can satisfy a broad audience.

Rumor aside, to a successor to D700, so very often quite user wants the sensor pixels moderate, I just want to have some machines full size of about 24MP or 18MP well as 36MP.
