Lenses / Re: Canon Double Rebates

Prices usually go up a notch right after the rebates end.  With the world in tough economic times, that might not happen.

I'm a bit suprised at those saying the 5D MK III sensor is the same as the 5D MK II sensor, when anyone who owns one and pushes the ISO up can see a dramatic difference.
Sure, if you shoot in a studio with good lighting at ISO 100, there is no need for capability you do not use, but that does not mean the sensors are the same.  I took dark frames from my 5D MK III when I got it and compared them to my 5D MK II, 1D MK IV, and they were worlds better.  A nice smooth dark frame that was not covered with red dots and banding.  At +3 EV, the MK III was black while the MK II  and 1D MK IV looked horrible.
Its a big advance in sensor technology, with all new on chip electronics, 8 channel readout.  Sure, its the same basic technology as the MK II, the D800, and every CMOS digital sensor ever made, So far, they all use silicon.

I've used both 5DII and 5DIII in the studio and within a studio environment I can find literally NO difference in the cameras, the upgraded AF system is useless since I shoot manual focus 99% of the time and the 5DII AF , however ancient, is still perfectly adequate. This is why I have not upgraded to 5DIII - it's almost a pointless upgrade for studio shooters - definitely pointless given the price AND the fact that the 5DII gives identical results. Currently, if I were to upgrade, the only way to go is medium format but still the 5DII is going to be a workhorse for a few more years I think - It's a bloody fantastic camera.
If you do not use the additional capability of the 5D MK III, you will see little difference, if any.  A Brownie 620 film Box Camera at f/8 will work just as well in a studio as a 35mm SLR.
Its only those who want the extra performance that will find the 5D MK III useful.
As to the sensor, you only need take a dark frame from each and boost it 3 EV in processing to see the difference.

I think that Canon guarantees it to be quiter than a Cannon

1.  Calibrate your monitor, else you are wasting your time to go further.
Here is a start  http://www.luminous-landscape.com/tutorials/understanding-series/und-print-mgmt.shtml
Note, you need to turn off printer management of colors in the printer driver and in photoshop.  Otherwise having photoshop and the printer both trying to manage colors will be bad news.
Alternatively, you can let the printer manage them and turn off photoshop from managing them.  Trying to find the proper settings can be obscure, and the tutorial should help.

Canon cameras do not write to a USB Hard drive thru their USB port, if thats what you were asking about.  The 1D X has a network port, so if you have a self powered drive with a network connection, that would work.

That is what I was thinking. Well they transfer to a external drive or does it have to have a computer?
You cannot push to anything external from the camera (unless you have the wifi accessory).  A computer with the proper drivers can pull images from the camera.  They are available for PC's and Macs.

The sticky topics at the top do not even try to give a illusion of being automatically managed.  they are for articles of general photographic interest, not intended to have a relation to the forum.
The sidebar on the right is automatically managed and shows topics with a approx 15 minute delay.  It is intended to guide users to current forum topics.
The forum has grown by a huge amount this year, so something is being done right.

Software & Accessories / Re: Tripod height?
« on: July 15, 2012, 11:06:23 PM »
I use a Benro C428 Tripod legs - 77.6"  max height and 26 lb rated  4 section tripod to get the height.  It is heavy at 6.2 lbs compared to most tripods that are in use for dslr photography.  I do not think they make a equivalent tripod any longer, I bought two of them when B&H closed them out for $278 each.
They handled my 600mm f/4 with large wimberly head just fine.  I can raise it above eye level just fine with out extending the center column,  The massive legs are almost 1.5 in dia.
The legs telescope to about 26 inches.

If you do not need a lens, its probably not a good idea.  Personally, I always find a excuse for buying a new lens.  I could buy a 16-35mm l, 70-200mm f/2.8L, and several others that might be part of the deal.

The main thrust of the patent is the variable Apodization filter, and it will be expensive. 
A different translation of the patent:
Especially the present invention is using the shape variable element which made variable form of the interface which two different media form about an optical system, and it is related with the imaging optical system which makes it possible to control the light volume of the light flux which passes an optical system.
The technique of making the apodization effect variable is disclosed by the Patent document 2. In the Patent document 2, by transmissivity's differing, and arranging two kinds of mutually unmixed liquids in a closed space via the interface of an approximate sphere surface, and controlling the output of impressed electromotive force, liquid interface shape is changed and the optical element which made the apodization effect variable is proposed.

There is a ton of very technical calculations in the patent, and it gives me a feeling that it is not something that will be cost effective to build and sell for a acceptable price.
I really don't expect to see one on the market.

Lenses / Re: New lens choice 28mm 2.8 is or 40mm STM?
« on: July 15, 2012, 08:19:34 PM »
I certainnly love my 24-105mmL for walk around situations.  For low light indoor use, the 35mm L is a favorite. The 40mm is, however destined to a lot of use if Canon's mirrorless body is small enough to carry in a pocket or purse.

« on: July 15, 2012, 08:15:42 PM »
Cameras can and do vary from copy to copy.  The sensors are difficult to completely test, and can have issues.  Returning a underperforming camera is the best solution.  My 5D MK III had a exceptional sensor with very low noise, but I returned it because of the invisible focus points in low light and bought a slightly used 1D MK IV for the same price.

Depending on your camera model, you can set the aspect ratio in camera and it will show guides in the viewfinder to you can frame it to fit the aspect ratio you want.  You will still need to crop to the aspect ratio in photoshop unless you use jpeg.

EOS Bodies - For Stills / Re: 5D3 macro question (Possible Noobish)
« on: July 14, 2012, 11:48:20 AM »
Wondering if someone can help me here, I have only had my 5d3 for about three weeks. I tried to do a few macro shots today, (Close ups of flowers) using the kit lens.

Autofocus was spot on looking through the view finder but I could not get the camera to take the picture, nothing happened when pushing shutter. If I dropped to manual focus on lens or zoomed further out it worked fine. I haven't done much Macro before, is there something I am missing?

Or was the camera telling me I was too close even though it looked ok?
The 24-105mmL kit lens is not a macro lens, so if you get too close, it will not achieve sharp focus and if your camera is set to single shot, the shutter will not release.
If you change to AI Servo, the shutter will release, and you will get a out of focus image.
It is difficult to tell by looking thru the viewfinder when critical focus is achieved.
If you are mounted on a tripod, use live view with 5 or 10X magnification and manually focus.
A 100mm Macro lens will do a better job.
