EOS Bodies / Re: Patent: Canon EF 180mm f/3.5L IS
« on: March 12, 2014, 09:41:24 AM »
These look like zooms based on the focal lengths and the zoom ratios listed.   I don't know much about how these patents work but I thought that primes usually only have one focal length listed.   Am I reading these wrong?

Here is a good article from RED that explains it a bit better with some visuals.

I tend to agree that everyone needs to calm down about this lens not having AF.  I don't think this lens was designed for the type of application where fast and accurate AF would be a big help.  In the video by Zeiss it seems like they are aiming for Medium Format type image quality.  If you take into account the 4k for this lens and the cost of a FF body such as a D800 or upcoming large MP body from Canon, it would end up costing a lot less than a MF kit (which typically aren't used in circumstances where fast and accurate AF is needed.)  Just my thoughts.

The new CPS page went up today. The evaluation loan period is going to be 10 days, not 7 days like previously mentioned. http://www.cps.usa.canon.com/loans/loans.shtml

Canon General / Travel Advice to National Parks in Utah
« on: September 02, 2013, 08:56:03 PM »
I have two questions I searched for answers to and couldn't find adequate enough answers.  I a m going to be going on a 2 week trip to Arches, Canyonlands, Capitol Reef and Zion National parks soon.  I will have all my camera gear in a backpack (cary on) and will be flying into Salt Lake City with a direct flight from a big city, so I wont have to worry about puddle jumpers and small overhead storage.
1. In the past I have put my tripod in checked baggage, but am wary of doing so now as I have a good tripod I wouldn't want damaged or lost.  It will not fit inside of my back pack. How do you travel with your tripods when you can't fit them in your travel bag?  I was thinking of taking it as my second "small item" but am not sure if it is going to be deemed as a dangerous object.
2. Any recommendations for little known places from people who have been to these parks recommend?

This was posted on Canon Rumors Twitter last night.  Possibility of the 70D before Easter.

This was posted on Canon Rumors Twitter about 3 hours ago. Maybe we might see the 70D soon. Easter isn't too far away.

EOS Bodies / Re: Canon EOS 7D Mark II Information [CR1]
« on: March 08, 2013, 08:20:04 AM »
Regarding the integrated versus non-integrated grip, could Canon produce some with and some without?  If they produce enough and sell enough this might offset the additional production costs of making two separate units as well as charging a little more for the integrated grip.  It would be nice to offer a choice of configuration similar to what you have for cars, but not to the full extent.  I think Canon has done something similar to this in the past with a film camera by having a better add-on grip but can't remember which one.

With this seemingly being marketed as a wildlife/sports camera, can Canon include f/8 center autofocus points to this like they do with the 1DX and soon to be 5D III?  I think the DX format Nikons can autofocus at f/8.  Would there be anything stopping Canon from implementing this on the 7D II other than policy or firmware?

The whole FF, APS-H, APS-C formats seems to be quite a polarizing topic.  As someone who has only shot with APS-C cameras (450D &7D) and only been able to compare IQ from each format, it seems like there are advantages to each.  FF for studio and landscapes, APS-C for the extra "reach" and APS-H is a compromise between the two that gives some additional reach for sports and wildlife while still delivering very good high ISO IQ (almost as good as the 5D Mark III).  I understand that it was a solution for Canon when FF sensors were too expensive to produce and NOT so that they could deliver faster frame rates, as some people seem to think on here.  I'd like to put in my thought sometimes but it seems like everyone gets their panties in a wad and can't keep even the most basic level of objectivity when it comes to discussing a possible return of APS-H sensors.  Instantly people flame anyone who even mentions that APS-H might actually be good. Gasp!
With that said, unless Canon can improve exponentially on the sensor technology of APS-C, APS-H delivers a lot of advantages with minimal investment in R&D.  I would definitely welcome a new 7D replacement with an APS-H sensor, whatever it's called.  There is definitely a market for Canon to have a "prosumer" body with all the bells and whistles it currently has.  The most common complaint I've heard about the 7D is IQ at both low and high ISO.  What could solve this problem is a move to APS-H! It would deliver better IQ while still providing some of the reach that APS-C delivers.  Yes it is a compromise but I'd see it as a very good one.  A move to FF for the 7D, as some people have wanted, would require the purchase of additional glass that is way out of the budget of most serious amateurs (myself included).  I have to 400 5.6.  A jump up to 500 would cost an additional ~5k for a used Mk I or ~9 for a MkII.  Unless someone wants to give me that money or I win the lottery, I don't see a 500 in my future any time soon.
Wow, that got long quickly.  I just think people need to tone down the rhetoric a little and try to come in with a little more of an open mind. Have a good weekend.

EOS Bodies / Re: How are dynamic range and sensor size related?

Roger from lensrentals wrote an article explaining some of this stuff.

An interesting article. I think the possibilities are pretty remarkable. Wasn't sure if this was the place to post but I figured it was the most relevant.
