Live Again: Zeiss Otus 85mm f/1.4 for $3,600 (instead of $4,500)

Zeiss Otus 85mm f/1.4

This deal was live 2 days ago with 2 units to ship. Now it has been put on eBay again, with 2 units to ship. To my knowledge Cameraland is a reputable dealer, I don’t know why the have the same exclusive deal live again.

The Zeiss Otus 85mm f/1.4 normally sells for $4,499 (Amazon), authorized Zeiss dealer and eBay seller Cameraland (99.8% positive ratings) has the Zeiss on sale for $3,599.99 (Canon mount). Not bad! Cameraland says:

We had an in store demo and these were shown and put back in the box. Because of this we won’t sell them as new never opened

Just 2 units available :-) The deal is very tempting but be sure to know all the details.

The Science and Technology behind Canon’s “L” Lenses

The Canon Professional Network posted an article about all the technology and science that’s behind a Canon “L” lens.

In several L-series lenses, both UD glass and fluorite lens elements have been combined to produce optimum results. With the continued increase in resolution of digital cameras, demands on lenses are increasing. It is likely, therefore, that UD and fluorite elements will be incorporated into a greater number of lenses, from wide-angle to super-telephoto.

Humor: What Canon really thinks about the DSLR Video Revolution

EOSHD‘s Andrew Reid made this short and hilarious video trying to figure out what Canon’s big shots think about the so-called “DSLR video revolution” Canon is actively promoting since years (well, at least since the EOS 5D Mark II). Andrew added his own subtitles to a viral video of a Spanish speaking man at a TV show. I am sure you will have a good and spontaneous laugh.

The video came out after Andrew Reid compared the EOS C300 ($12,000) to the Samsung NX1 ($1,500). As he says, after having made the comparison he “couldn’t help imagining this“.
