Third Party Manufacturers / Re: FUJIFILM'S latest, X-T1 ?
« on: January 28, 2014, 03:09:31 PM »
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

"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.

Canon, if you are reading...Stick the 70D sensor in a body like this and make some EF-M mount lenses with aperture rings!

I wasn't trying to bash Canon. I was genuinely curious why they would release a press release before acting. I answered my own question by finding Nikon's press release and realizing they didn't want to be seen as reacting to Nikon.

Kudos to both companies for acting.

While it's certainly good that Canon is going to donate aid, is it just me or does a PR release announcing that you are planning on giving aid as soon as you can make up your mind who do give it to seem very odd? Especially, when the stories covering the tragedy often mention their immediate need.

EDIT: Ah, I just went to Nikon Global and found this:

EOS-M / Re: The Next EOS M in 2014 [CR2]

For the love of god, Canon. Stick the 70D sensor in a G1X style body with a good EVF and create some EF-M lenses with an aperture ring. There is no shame in copying Fuji when sales are falling. It...would...sell!

People are studying what appears to be a CG marketing image way too closely.

Who here thinks they really placed a cloth across the new body and photographed it to make this image? Raise  your hands...

"... Canon will start from the white world ..."
So rife with politically incorrect double entendre it almost seems like an Onion headline.

That sounds like a very literal translation. I wonder if it means something like "Canon starts from a blank slate".

I'll ask my Korean colleague when he comes back from lunch.

Software & Accessories / Re: Will the new MAC Pro support 10 bit colour?
« on: November 06, 2013, 11:04:38 AM »
This article says yes:
"The guys at BasicColor have also informed us that Mavericks now supports full 10 bit video output via Thunderbolt, with a compatible video card."
