[Review] EOS 60D vs T4i/650D (and Canon DSLR deals, Amazon GoldBox)

Share

Another >12 min video review by DigitalRev: EOS 60D vs Rebel T4i/650D. Which one is better suited for your needs?

In this video we take a little trip to the Ani Com fair, which showcases a load of people dressing up in maids and schoolgirl uniforms, to compare two of Canon’s most popular DSLRs: the EOS 60D and recently released 650D. Just which one is right for you?

Next, I found a sort of Goldbox deal going on on Amazon, for six different Canon DSLRs kits (click here to see them all). The DSLRs kits are:

[Review] Rebel T4i/650D/X6i Full Review By DPreview

DPreview published the awaited review of the Rebel T4i/650D. I didn’t expect it to be that positive, final score is 77/100. However, the “biggest disappointment [...] lies in the camera’s ‘hybrid’ AF performance in live view and video modes“. No surprise here. The positive aspects:

  • Comprehensive touchscreen interface that is intuitive and efficient
  • High image quality with good balance between detail and noise reduction in JPEG output
  • Good subject tracking AF in viewfinder shooting mode (compared to mirrorless competition)
  • 5 fps with ample buffering in JPEG-only mode
  • Very responsive operation, with menu access available even when buffer is full
  • Good-looking video output with manual exposure and audio controls
  • New ‘hybrid AF’ is a step forward (compared to its predecessor)
  • Built-in lens correction for vignetting and CA
  • Effective HDR, lowlight and noise reduction multi-exposure modes
  • Wireless strobe triggering via built-in flash
  • Eye sensor to toggle LCD on and off
  • Built-in stereo mics
  • External microphone socket
  • Updated LCD screen minimizes fingerprint smudges from touchscreen use
  • High quality raw converter in software bundle

[Video] Video Modes Compared: T4i/650D vs 5D3 vs 1D-X

Gizmodo compared the video modes of three Canon DSRLs in a price range from $1000 – $7000. It’s Rebel T4i/650D vs EOS 5D Mark III vs EOS-1D X. From entry level to top end.

[...] all three cameras [...] shot the same scene with the same lens (Canon 24-105 f/4) and settings (f/9, 1/50, ISO 100). We use a picture style with sharpness at 0, contrast at 0, and saturation at -2. We adjusted the focal length on the crop-sensor t4i to match that of the other two cameras. Obviously this isn’t completely scientific, but we did our best.

The outcome may surprise you. While the EOS 1D-X is obviously the best performing gear here, and the 5D Mark III is second placed, the performance of the Rebel T4i/650D is by far not so much worse as the others cost more (we’re talking about video modes here). See for yourself, and do it by enlarging the video to full screen (otherwise moire artifacts are hard to spot).

[Review] Rebel T4i/650D (and EOS M) Hybrid AF System – A Video Review (and updated EOS M pre-order list)

DPreview wanted to have a closer look at Canon’s recently introduced Hybrid Auto-Focus system. This AF-system is featured on the Rebel T4i/650D and the EOS M. Does the AF-system improve AF in live view? How well is this technology suited for mirrorless cameras? The videos show how Hybrid AF works (video above), and compares this AF-system both to the conventional phase-detection AF and to the Panasonic DMC-G5 (video below). If you live in Europe you can pre-order the DMC-G5 at Jessops, or find it on ebay. If you live in the US you can pre-order pre-order at B&H and Adorama). Whereveer you are located, you may pre-order at DigitalRev. An EF-S 18-135mm STM was used for the test, this lens has been designed specifically for Canon’s hybrid AF-system.

[Patent] Another Canon Patent For Improved Phase-Detection Autofocus (next mirrorless sensor?)

Conventional approach (left) and patented approach (right)

Egami (machine translated) spotted another patent filed by Canon and related to methods that aim to improve the performance and accuracy of the phase-detection AF. This is the second patent in a few days – the first one can be seen here. Such an AF method is featured on the Rebel T4i/650D and on Canon’s recently announced mirrorless camera, the EOS M. Note that such an AF method is particularly useful on a mirrorless camera, given that such cameras, since they are missing the mirror, can not focus in the “traditional way”.

As far as I can tell, the patent details methods to increase AF performance by eliminating problems caused by the angle of incidence of the light: “[...] reduce the diffraction limit by a high refractive index layer“. Another discussed issue is the reduction of the pixel size (higher resolution??). I am more and more confident that both patents are related to an upcoming sensor which, I guess, will be at the heart of the more pro-oriented mirrorless camera most of us are expecting to be announced in September at Photokina.

  • Patent Publication No. 2012-151367
    • 2012.8.9 Release Date
    • 2011.1.20 filing date
  • The diameter of the spot light focusing of the micro lens
    • Determined by the numerical aperture and λ the wavelength of the incident light
    • By the wave nature of light, not smaller than the diffraction limit
    • When the pixel size below the diffraction limit, pupil division is impossible
    • ⊿ = 1.22 * (λ / n * sinθ) diffraction limit
    • ※ This angle θ is half the chance of lens optical system was synthesized in the micro-lenses and layers
  • Related art
    • There is a light flux can not reach into the openings of the light-shielding layer of the phase difference AF pixel for the image plane, the light-receiving efficiency is reduced
    • Although the distance can be shortened and the photoelectric conversion unit if microlens back-illuminated (BSI), if the pixel consists of a low refractive index layer in the layer lens +, for total internal reflection occurs, can not be expected to increase the angle
  • Canon’s patented
    • To reduce the diffraction limit by a high refractive index layer
    • Structure of the pixel
      • Within a layer lens, and light shielding layer formed between the microlens
      • The high refractive index layer, filled between the lens and the light-shielding layer in the layer
      • The low refractive index layer, a light shielding layer filled between the microlens and
      • Optical system consisting of micro-lens and lens in the layer, connecting the focal point in the PD
      • A case
        • Λ = 540nm wavelength of the incident light
        • 1.6 refractive index of the microlens
        • 1.45 refractive index of the low refractive index layer
        • Layer of high refractive index lens and in the layer refractive index n = 2.3 (silica Sio 2 of the prior art is n = 1.46)

Canon Recalls 68,200 T4i/650D Due To Possible Allergic Reactions

Image Credits: engadget.com

These are news I do not like, Holy Whatever! The Rebel T4i/650D is a cute little DSLR, I played around with it and didn’t get any skin rash. Engadget reported it first, let me quote the core of the message:

Hazard: A chemical used in the camera’s rubber grips can result in a reaction that changes the grips from black to white and poses a risk of skin irritation to the consumer.

Ok, no reason to panic. Check if you are involved (click here for the whole story):

Description: This recall involves EOS Rebel T4i digital SLR cameras with a 12-digit serial number that contain a second digit that is a “3” or “4” and a sixth digit that is a “1.” Serial numbers are printed on the bottom of the camera. The Canon logo and the model name are printed on the front of the camera.

Sold at: B&H Photo, Best Buy and camera and mass merchandise stores nationwide and Amazon.com and other online retailers between June 2012 and July 2012 for between $850 and $1,200.

Canon will replace the rubber grips free of charge. In the USA you can ring 855-902-3277.

For the time being, according to reports, there is only one customer affected by a «minor rash» after having touched a Rebel T4i.
