EOS Bodies / Re: Is Dual Pixel Tech Coming to the EOS 5D Mark III?
« on: February 28, 2014, 01:08:52 PM »
Didn't Chipworks or someone already do an analysis on the 5D Mk III CMOS? I feel like they would have noticed something like this.

Edit: Yeah, they did. Here's a link: http://www.chipworks.com/en/technical-competitive-analysis/resources/blog/full-frame-dslr-cameras-canon-stays-the-course/

Also: https://chipworks.secure.force.com/catalog/ProductDetails?sku=CAN-EOS_5D_MarkIII_Pri-Camera&viewState=DetailView&cartID=&g=&parentCategory=&navigationStr=CatalogSearchInc&searchText=canon%20digic

I really think they would have noticed the different architecture if dual-pixel tech was present.

43 cameras is not a large sample size. Also the 13 unknown cameras don't appear in the % chart and therefore skew all the results.

It's a great lens for portraits. It's less versatile than the 70-200 v2 as a portrait lens, but you gain macro shooting ability and the size/weight savings. It's a tough choice, so I own both. Though also shoots sports with the 70-200 so it has its own justification.

Come on 70D sensor!!!

I saw this ad on craigslist and thought it was amusing enough to share... ;D


If the surface of the sensor was reflective enough to effectively replace the mirror, I don't think it would let enough light through to be an effective sensor. Also, the sensor itself is a delicate bit of electronics. I would be concerned with it's durability when bouncing around as well as the durability of the flexible electrical leads connecting it to the rest of the camera's circuitry.

If it actually focuses on moving subjects it will steal a lot of DSLR sales. I LOVE my X-E1 and the Fuji lenses, but if I am heading into a situation with moving or otherwise difficult subjects, I grab the Canon every time.

EOS Bodies / Re: Patent: Canon Curved Aperture Diaphragm

It wouldn't affect curvature of field, but it sounds like a way to correct for focus shift (the 50 1.2 L has been known to have focus shift at close distances)

You're right. I wasn't thinking it through. As the iris closes from the wide open position, the optical axis of the lens would move forwards or backwards depending on which direction the curved diaphragm was installed.

Wouldn't that result in field curvature? Or maybe this is a way to correct that?

EOS Bodies / Re: Patents: Canon 85mm f/1.8 IS, 100mm f/2 IS, 135 f/2 IS

The patent for the 135mm says f/2.8 not f/2

Canon General / Re: What is the problem with Canon

I usually kick it to 160 because of all this natural iso I really don't understand (I know... I should bother to read up).

I believe this has been shown to be false.  ISO 160 appears to have lower noise because it's really ISO 200 that is then digitally underexposed to get to an effective ISO of 160. This has the effect of suppressing noise, but clipping highlights and limiting DR.

What are you wanting to sell the 50L for?


I'll sell you mine for $1250. It's 3 months old.

Third Party Manufacturers / Nikon makes development announcement for D4S
« on: January 06, 2014, 09:12:30 PM »
"As Nikon's new flagship model, the D4S will offer advances over the Nikon D4 digital SLR camera that include even better image quality enabled with adoption of a new image-processing engine, and more advanced autofocusing performance."

This doesn't sound like a new sensor is in the works, which I find very surprising. Maybe they aren't ready to tip their hand yet.


EOS Bodies / Re: EOS 5D Mark III & Third Party Batteries
« on: December 12, 2013, 09:20:36 AM »
"My contact at Canon explained this was an effort to cut out counterfeit batteries claiming to be Canon batteries."

If that is the case, then they have failed and should remove this test from the firmware. 3rd party manufacturers have already defeated the check making it only a hassle for owners who have older off-brand batteries. Of course they won't because that was their intent...trying to annoy people to only buy Canon batteries.
