iPhone 4S / Canon 5d MKII Side by Side Comparison

***You can download the full 1080p version of this video for a more accurate presentation.

Here's a "fair" test between the iPhone 4S and the Canon 5D MK II. I made a little rig that allowed me to shoot both cameras at the same time side by side. All scenes are perfectly synced together so you can pause and scrutinize the frames! See photo of the makeshift rig in the photo area.

Exposure, shutter speed, frame rate and picture style were matched as close as possible between the two cameras. (I used the Zacuto Z-finder to help me adjust exposure for both iPhone and 5D)

This test shows that the tiny F2.4 lens and sensor on the iPhone are pretty nice. It even got a little depth of field!

I did not overlay the exact ISO and Stops 5D settings per shot. It was too much to keep track for this simple test. To be fair I matched 5D exposure to the iPhone so no "Cinestyle" / 24p here.

Here are the settings:

iPhone 4S

- AE.AF locked. That's all you have!

Canon 5D MKII

- Canon 50mm 1.4
- ISO 160 ~ 640 (varied per shot to match the iPhone)
- F 7~22 (varied per shot to match the iPhone)
- Shutter 1/60th
- Auto WB
- Standard Picture Style
- 1080p 30

Canon announces new flagship DSLR: 1Dx with improved Video capabilities

Canon announced the company’s newest flagship professional DSLR today, the 18 megapixel full-frame Canon 1Dx. The 1Dx will sit atop Canon’s model line as an update to both the Canon 1Ds and the 1D Mark IV, and is expected to debut for $6800 body-only in March 2012.

The 1Dx will feature dual DIGIC 5 processors, which Canon claims offer approximately 17 times more processing power than the previous generation DIGIC 4s.

Those looking for an upgrade to the 5D Mark II for video capture may find a friend in the 1Dx, as it is capable of 1080/30p/25p/24p HD video capture, with options for 720/60p/50p as well. The image sensor has been designed with video in mind, meaning that downsampling errors and the resultant moire effect should be significantly reduced. The file system’s 4GB limit has also been worked around, with an automatic file splitting functionality enabling up to 29 minute and 59 seconds of continuous video capture.

The camera also supports two methods of SMPTE-compliant timecode embedding, Rec Run and Free Run, to ease syncing up multiple cameras in post. The 1Dx will also support both intraframe (ALL-i) and interframe (IPB) compression, to aid post-production and editing workflows, depending on need. The camera also offers manual audio level control both before and during video capture with the internal monaural mic or an external stereo microphone.

Canon's all new full-frame CMOS sensor ensures that video footage captured on the EOS-1D X will exhibit less moiré than any previous Canon model, resulting in a significant improvement in HD video quality. A desired feature for many documentary filmmakers using Canon DSLRs was to enable recording beyond the four gigabyte (GB) file capacity and the EOS-1D X is the answer. The new camera features automatic splitting of movie files when a single file exceeds 4GB. The new file splitting function allows for continuous video recording up to 29 minutes and 59 seconds across multiple 4GB files; no frames are dropped and the multiple files can be seamlessly connected in post production, providing filmmakers the recording time they want in the same convenient DSLR form factor. The camera records Full HD at 1920 x 1080 in selectable frame rates of 24p (23.976), 25p, or 30p (29.97); and 720p HD or SD video recording at either 50p or 60p (59.94). SD video can be recorded in either NTSC or PAL standards.

The Canon EOS-1D X also includes manual audio level control, adjustable both before and during movie recording, an automatic setting, or it can be turned off entirely. A wind filter is also included. Sound can be recorded either through the internal monaural microphone or via an optional external microphone through the stereo mic input.

The Canon 1Dx offers USB transfer, but will also sport a wired gigabit Ethernet port for stable wired transmission of video and still images at up to 1000BASE-T transmission speeds. That should allow not only faster transmission of files, but longer, more practical connection solutions for professionals. For on-camera storage, the 1Dx will eschew SD storage in favor of dual Compact Flash cards.

The low-light capability of the EOS-1D X is evident in its incredible ISO range and ability to photograph in extremely low-light conditions. Adjustable from ISO 100 to 51,200 within its standard range, the new model offers a low ISO 50 setting for studio and landscape photography and two high settings of 102,400 at H1 and 204,800 at H2, ideal for law enforcement, government or forensic field applications.

Apple Wild West UI Design (HaHa)


hahaha: gizmodo is totally right when stating "Yeee-haw, Apple buckaroos! Whooz ready for some good timin', multitaskin'? Who wants their iPhone served up with a hot bucket'a grits? HOOOOOOOOOOO BOY. Jonny Ive's deep in the hooch pan again? Saddle up, grab yer partner, and let's make some truck-ugly apps!"

What happened to the GUI design guidelines of Apple? Why do we have to use western-style user interfaces - and why can't we change the looks to something uhm less contemporary?

Nikon D800 36MP Camera Announced. Canon 6D of 5D MKIII to follow as a response?


Nikon Rumors is reporting a 36mp D800 coming in the next 30-60 days at a 99% probability. As Canonrumors pointed out, this can be a great thing for Canon users: New full frame sensor cameras, as well as a 5D MKIII or a 6D could be possible. Well, we are desperately waiting, currently equipped with two Panasonic GH2 Cameras that are hacked to the extreme. See an example Video on Vimeo (66Mbps Hack). If there is no alternative coming out soon, lots of people will stick to their GH2s, as they are currently the best there is, especially when using the Atomos Ninja (see a great Example on the Atomos Ninja with the Panasonic GH2).

[UPDATE] Nikonrumors posted More Nikon D800 bits and pieces: 100% Viewfinder coverage, improved AF with face recognition, SD+CF dual memory card slots as well as a USB 3.0 possibility. The question remains, why not CFAST? On another post, the ISO range is said to be 100 – 6400, ISO LO @ 50 and ISO HI-2 @ 25600. We can only wait and see...

New Apple iPhone 4S – mainly lens improvements, but: great optics indeed! (plus: Siri A.I.)

Everyone's talking about the new iPhone 4S that was announced by Apple recently. But is there more to it than improved optics? Even if not, the camera is a huge improvement over the previous model: 1080p video recording, 8 Megapixel photo sensor, f/2.4 aperture.

Behind all the updates, the most interesting is HSDPA support. In countries such as Austria or Japan, where HSDPA is widespread, this is a very welcome hardware upgrade. Still, why is there no HSPA+ support? In cities with a weak broadband coverage (everything above a few MB upstream) - such as Vienna, this is really akward. We still have to fall back to the Samsung Galaxy S2 i9100, which offers HSPA+ among other great features. So the "only" killer feature of the Apple iPhone 4S remains the greatly improved Camera - which is to question, concerning the price of such a gadget. An Amazon Search for the iPhone 4S yields no results, obviously, since the device is said to be available from mid October.

Our recommendations: wait for the iPhone 5 and get some real gear instead.

1) Get a Canon PowerShot S100 for Photo and Video
2) Get a SONIM XP5300 3G FORCE if you need a phone that actually works.
