Canon EOS 5DS and EOS 5DS R start shipping June 14 in the USA (says B&H Photo)

bhy

Edit: EOS 5DS and EOS 5DS R still not available for pre-order at Amazon EU.

This morning we reported that the EOS 5DS and EOS 5DS R will start shipping worldwide starting mid June. Now we got the confirmation, at least for the US market.

B&H Photo updated their Canon EOS 5DS and EOS 5DS R product pages. It says: “Will begin shipping Sun, Jun 14 (subject to availability)“. Remember that orders will be filled on a first come first serve basis. If you still didn’t order the EOS 5DS or EOS 5DS R, then this may be the right moment.

Canon EOS 5DS and EOS 5DS R shipping mid June

Based on what I have been told, various big European retailers are expecting first EOS 5DS and EOS 5DS R batches more or less by the end of next week/beginning of the week after. Guess this is valid also for other retailers around the globe, especially in the USA.

Keep in mind that shipping dates may also be delayed because of unexpected issues. However, I am pretty confident both the EOS 5DS and EOS 5DS R will start shipping all over the globe from  mid June, with some delays to the last June week for smaller countries or markets Canon considers not a priority.

Canon patent to increase dynamic range with use of Neutral Density filter (using Dual Pixel AF)

p

Canon filed  patent to increase dynamic range by using a Neutral Density (ND) filter on half of the measured field. This is a pretty complex one and I am not 100% sure I got it right (any help welcome).

The described system works by getting different degrees of light intensity from the Dual Pixel auto-focus (DPAF) points (i.e. split pixels) on the sensor. The patent says the ND filter is placed on 50% of the measured field: different amounts of light hit the split AF pixels needed for DPAF (this means both of the split pixels are used to measure the DR). The result is an output that’s able to render an increased dynamic range to the sensor, and a easier to measure differential signal from the DPAF points. It is not as easy as I am trying to put it :-) To learn more about Canon’s Dual Pixel Auto-Focus technology have a look here.
