Perhaps you have real sources, and perhaps English isn’t their strong suit. However you represent them as engineers, and one trait engineers typically share is attention to detail. One trait Europeans typically share is fluency in multiple languages. A European engineer misspelling “format” is highly unlikely. Format in German is format. Format in Dutch is formaat. Format in French is format. Format in Italian is formato. Format in Croatian is format. Format in Spanish is formato. Format in Czech is formát. Format in Swedish is formatera. It’s never fromat. You’ll find that aspect is similarly never apsect.HarryFilm said:---3kramd5 said:Here’s the thing:kaihp said:Excuse me, but that's not how chips are (normally) placed on a wafer. They are placed in a strict Manhattan corner-to-corner pattern, so you can run a (diamond) saw through on both the horizontal and vertical.HarryFilm said:Well now that you said it, I CAN MOST DEFINITELY SUGGEST TO YOU that indeed Canon is looking how they would layout multiple Medium format sensors of DCI 8k (8192 x 4380 pixels) of 56mm x 42mm size. Here is the below graphic used for suggested layout of the chips on 300mm silicon wafers. The aspect ratio difference of 1.89 imaging photosite vs the actual 4:3 sensor aspect ratio is PROBABLY due to the in-between-lines-of-photosites being using for DPAF or specialty edge detection or OTHER colour-filters photosites (i.e. extra Yellow channel?)
If there is enough economic incentive (and at this size of dies, there probably is), you could make a setup as shown in the graphic. It would 'just' require a very different handling of the wafer at the dicing (sawing) and picking stage.
I've just never seen a setup like this in the real world.
Harry Film either has people trolling him, or, more likely he invents his sources and the reference material. His claims are typically outlandish and rife with technical errors, but it’s all in good fun.
I should note everyone that the chip layout is from my Euro-sources which THEY MADE -- their English is only decent-enough or simply outright terrible. I would expect that and even I didn't notice the mistakes pointed out by an earlier forum poster.
Anyways.... NO! I DO NOT make up my sources ....BUT.... they are -S-O-U-R-C-E-S- which means PLURAL! That also means the information is disparate and unconfirmed so I personally cannot vouch for their accuracy....BUT....very much like detective work, when you start seeing multiple "witnesses" tell the same story, it means you need to take a closer look at what is being discussed to find some commonalities.
(i.e. what "sources" are MY SOURCES using?) Reporting is all about fact-finding and correlation....AND...while correlation does not necessarily specify causation, you ALSO cannot ignore many correlations either!
Sooooo.........All I can say with reasonable confidence, is that Canon IS TESTING a medium format around 50 megapixel, high frame rate (20 fps to 25 fps burst rate) stills camera with DCI 4K full-sensor sampled 4:2:2 video! I expect an official announcement sometime in February to April 2019.
I can ALSO STATE with reasonable confidence that an update or replacement for the Canon XC-15 camera is PROBABLY headed for a Photokina 2018 announcement. It is probable that it will be a one-inch sensor and will have 10-bit 4:2:2 interframe 60 fps encoded video AND will have an interchangeable lens system.
And finally, a short-flange APS-C sensor mirrorless that looks like an Canon M5 may also be announced either at Photokina or soon after.
THOSE are what MANY of MY SOURCES are saying!
Again, WE SHALL SEE WHAT HAPPENS !!!
If you really have someone sending you this stuff, take it with a mountain of salt; you’re probably being trolled.
