EOS Bodies - For Stills / Re: Combining Sensors...is it possible?
« on: May 01, 2012, 12:57:12 AM »
Developmental costs would be pretty high.  Digic processors are only setup to handle one sensor.  Balancing color and brightness between sensors, combining images, synchronizing them, and getting rid of 4X the heat would probably push the cost out of sight, and even then, a large sensor would likely outperform the combination.
 
I'd never buy one over a single sensor, too many compromises that are not necessary.  For a multimillion dollar aerospace uses where a multi million dollar supercomputer reassembles the images over a period of days with a staff of scientists to manage it is one thing, a consumer camera is another.

Your reasoning makes a lot of sense. It seems like it would be pretty impractical to use an arrayed sensor setup like the ones they're using for telescopes. I just thought it would be pretty cool if it actually was cheaper than the equivalent sized sensor and could offer the same image quality. Thanks for the response!

The Gaia spacecraft will use 106 CCD sensors to survey the stars and will have a combined resolution of about 938MP.

That was an interesting read. Same principle here I guess, just trying to figure out if it'd be worthwhile to do something like that in a consumer DSLR.

How do you know this? I work in the semiconductor test industry, and while I don't know for sure I believe that cost of producing larger IC's goes up way faster than producing more smaller.
Sure they do, they have lower yields, but unlike a PC motherboard for example you have the additional cost of trying to precisely match and align things. Not to mention anyone can buy say an ARM processor for under $10, but you won't see an ARM core systems on the top 500 supercomputer list.

At some point / volume it makes sense to put everything on one piece of silicon, unless you're at the cutting edge when you need a 1000 image sensors or CPUs for your cutting edge design.

I figured that there's probably some obvious costs or difficulties involved with this sort of technology which is why I've never heard of anything like this before.  I think it's impossible that nobody has ever looked into this as a possible way to lower large-format digital sensor costs.

Link seems to be broken, but do you think 4 smaller sensors would be significantly cheaper than a 35mm sensor?

Technically it may be a little cheaper for the sensors themselves, production costs and yields tend to go up a fair degree with increasing die size, however that would be offset by increased costs of the sensor read electronics and assembly costs. I'd also assume they'd be a gap between sensors which might not matter for that sort of application because maybe they always interpolate multiple frames. I suspect in that particular case it makes sense because they are dealing with a size well beyond any practical manufacturing techniques for making it on a single die.


Sorry the link didn't work for you, here's a different one about the same story:
http://www.photographybay.com/2012/04/30/3-2-gigapixel-camera-has-189-image-sensors/

And ya I was specifically referring to the cost of the overall sensor.  I'm not sure, but I figure since the cost of sensors relative to their size is exponential that combining smaller sensors would be more cost effective.  Oh and I was also just curious  ::)

I just read an article over at PopSci about a new camera being constructed that uses dozens of large format sensors in a large array to create images.  It got me to thinking about using a similar technique in DSLRs.  Why can't a camera have say four m4/3 sensors in a 2x2 pattern to make a similar sensor to 35mm?  Anybody have any ideas?

Here's the article:

You can learn a ton from SLRlounge's excellent Lightroom series (117 videos and counting).  Awesome video's and extremely informative.

Thanks for that one!  I just checked it out and watched the first 10 little videos.  Very comprehensive.


No problem! ;D

How about the Bigma?  The Sigma 50-500 seems to be held in decent regard, and it has an awesome range.  It sure is huge though...

Lenses / Re: What is the most EXOTIC Canon lens?
« on: April 13, 2012, 10:21:50 PM »
I would say, in order:

1200mm f/5.6L 1.4x FD (extinct)
1200mm f/5.6L
65mm MP-E
17mm f/4L TS-E
8-15mm f/4L fisheye
50mm f/1L
150-600mm f/5.6L nFD
38-76mm f/4.5-5.6 (rare, but not desirable)
35-80mm f/4-5.6 PZ (rare, power zoom)

Third party EF mount:

200-500mm f/2.8 Sigma

The Canon 8-15 F4L is pretty unique.  If I'm not mistaken, I don't think there has ever been another fisheye zoom lens on the market.


Tokina has the 10-17mm fisheye for crop cameras.
http://www.tokinalens.com/products/tokina/atx107afdx-a.html
Which is the same as the Pentax 10-17mm
http://www.photozone.de/pentax/132-pentax-smc-da-10-17mm-f35-45-edif-fisheye-review--test-report

Whoops never saw those before. I stand corrected!  ;D

I just want to be able to use Instagram. I think a good filter will make my photos look way better.

Lenses / Re: Tamron 24-70 f/2.8 VC Available for Preorder
« on: April 05, 2012, 10:16:49 PM »
Comparing the MTF charts from the Tamron to the 24-70L I it looks like the Canon is going to have better sharpness.  And for nearly the same price, I'd take the robustness of the Canon over the IS and future compatibility issues of the Tamron.

EOS Bodies - For Stills / Re: Customer wants to buy Nikon D800 (funny)
« on: March 31, 2012, 10:06:07 PM »
The video is really funny, and that ending was great.  I'm wonder how many people are willing to plop down $3K+ for a new camera and are swayed purely by MP.  I mean that's a lot of money to not fundamentally understand the equipment you're buying.

Canon non-EF Lenses (TS-E, FD, etc.) / Re: 600mm FD f4.5
« on: March 31, 2012, 04:09:20 AM »
Hand held a 600mm lens without IS?  Ridiculous, and that's not even taking into account that it must have weighed a ton holding that thing. Must have some pretty big guns lol (not talking about lenses)  ;)

Canon EF Prime Lenses / Re: canon 300f4L IS with keno 1.4x TC
« on: March 31, 2012, 04:05:23 AM »
That's some spot on focus right there!  I could've tried that shot 20 times with my T1i and unless I got incredibly lucky, would never have walked away with a photo so sharp and clean.  Time for some new glass I guess (Ignoring my serious 5d mark iii lust)

Anyways just out of curiosity, was body was this on?  And were you using AI Servo? Great shot btw  ;D
