Lenstip reviewed the Sigma 18-35mm f/1.8 DC HSM lens, the UFO: Unbelievable F-stop Object. As you most probably know if you live on this planet, the Sigma 18-35mm f/1.8 is the first zoom lens for APS-C DSLR to deliver constant f/1.8 over the whole zoom range. As if that wasn’t amazing enough, Sigma managed to give a more than fair price to this lens: $799, while most people was expecting a price tag at least over $1000. So, the suspect was Sigma could have had to make some compromises on some aspects of the lens. Nope. The featured review shows once more how outstanding the Sigma 18-35mm f/1.8 is. Read more after the break.

Magic Lantern Raw on the Canon EOS 50D Review (EOSHD)

Andrew Reid from EOSHD posted a comprehensive review with lots of tech talk and details about how the Magic Lantern RAW hack performs on the since long discontinued Canon EOS 50D (here on eBay). The EOS 50D was never thought to shot video, although someone discovered it has a microphone socket.

If you are into this things, if you want to recycle your old 50D and start shot some video, then this review is for you. The hack is still under development, but it already works fine. Quoting EOSHD:

Pros

  • Best of the APS-C Canons for raw video
  • 14bit uncompressed raw video at up to 30fps
  • Good flexibility in terms of resolutions and aspect ratios
  • Useful crop mode with extremely high image quality
  • Good dynamic range and low light performance
  • Superb build quality and extensive manual control
  • Extremely cheap on the used market and relatively common
  • Well suited to anamorphic lenses
  • Bonus H.264 1920x1080p recording mode

Cons

  • 5D Mark III is superior
  • Full sensor mode resolution limited to 1584 x 1058
  • Requires anamorphic lens to get the best of the full sensor mode
  • Moire and aliasing unless using 1:1 crop mode
  • Although a cheap camera body, requires expensive CF cards
  • Poor LCD visibility in strong sunlight
  • No articulated screen as found on newer Canon DSLRs
  • Glitchy exposure in crop mode, currently
  • Currently some disturbing bugs such as incorrect black levels and magenta tints
